There are separate assemblies for the logic cards, receiver, exciter, power amplifier and power supply sections. This service manual provides installation, operation, programming, service, and alignment information for the VIKING VX LTR Repeater, Part No. 2422009-232/234. This repeater is programmed with a laptop or personal computer using the repeater software, Part No. 023-9998-297. 1.2 REPEATER IDENTIFICATION When the repeaters are installed in an environment that contains small airborne particles, e.g. grain dust or salt fog, the repeater cabinets need to be sealed. A heat exchanger, i.e. air conditioner, is then required to cool the cabinets. The air conditioners must be suited for the environment. Each low power repeater (75W) requires >1200 BTU/hr dissipation to maintain exterior cabinet temperature. Each high power (160W or 175W) requires >2100 BTU/hr dissipation to maintain exterior cabinet temperature. The repeater identification number is printed on a label that is affixed to the inside of the repeater cabinet. The following information is contained in that number: Repeater ID Revision Letter Manufacture Date Plant Warranty Number 20XXX A 24 A 12345 Week 3 Year A= Waseca 1.4.1 TRUNKED SYSTEM A trunked radio system, as defined by the FCC, is a "method of operation in which a number of radio frequency pairs are assigned to radios and base stations in the system for use as a trunk group". Trunking is the pooling of radio channels where all users have automatic access to all channels reducing waiting time and increasing channel capacity for a given quality of service. 1.3 MODEL NUMBER BREAKDOWN The following breakdown shows the part number scheme used for the Viking VX. 242-200 9 - 2 3 X 2 = 25-75W 9 = 900 MHz Trunking concepts are based on the theory that individual subscribers use the system a small percentage of the time and that a large number of subscribers will not try to use the system at the exact same time. 4 = 75-160W 3 = 12.5 kHz VIKING VX 1.4.2 LTR TRUNKED SYSTEM LTR repeater operation is automatic to where a logic module performs the call functions and communicates over-the-air to subscriber units. There must be one repeater for each RF channel and each repeater contains a logic module responsible for signaling on its own channel. Logic modules then share information with all other repeaters in the system via interrepeater communication. 1.4 REPEATER DESCRIPTION The VIKING VX 900 MHz repeater is designed for operation in a LTR system. It operates on the 900 MHz channels from 935-940 MHz (repeater transmit). The repeater receive frequencies are 39 MHz below these frequencies (896-901 MHz). Channel spacing is 12.5 kHz and RF power output is adjustable from 25 to 75 watts (Part No. 242-2009-632) or 75-160W (Part No. 242-2009-634) with the high power amplifier. System control is accomplished by the exchange of data messages between radio and repeater. The LTR system trunks up to 20 channels by utilizing continuous subaudible digital data applied to the RF car1-1 October 1999 Part No. 001-2009-201 INTRODUCTION AND OPERATION 2000 Series Service Kit - This kit contains an alarm wire harness, extender power cable, programming kit, extender card, extender harness, and a TIC bias cable. These items are used when tuning the repeater and while troubleshooting. rier simultaneously with voice modulation. Therefore, no dedicated control channel is required and all channels are used for voice communications for maximum system efficiency. Each radio is assigned a Home Channel which sends system commands to specified radios. There are normal words and special function words. The special function words are used to initiate special calls; Telephone, Unique ID, and Data by Unique ID. The special function words are also used for command calls: Interrogate, Kill, Reassign, Electronic Serial number Authentication, Registration, DeRegistration, etc. Low Power Supply with Battery Backup - This power supply is for the 25-75W repeater and is equipped with battery backup (see Section 2.5). High Power Supply with Battery Backup - This power supply is for the 75-160W repeater and is equipped with battery backup (see Section 2.5). Since each repeater is responsible for signaling on its own channel, this approach lends itself well to a distributed processing logic controlled approach requiring only a small logic unit within each repeater. These processors share information over a communication path. This architecture permits each repeater to be autonomous. A failure in one repeater leaves the remainder of the system intact and operational. Battery Backup Option - This option can only be installed by the factory. It includes the battery backup module that resides in the power supply and the necessary interconnect cabling to connect the repeater to the batteries (see Section 2.5). Battery Backup Cable Kit - This kit provides the cables required for connecting the terminal strip on the power supply to the 12V DC battery (refer to installation instructions 004-2000-224). The repeaters may be connected to a larger system. This allows the system to perform some of the previously mentioned calls. The RNT may communicate from one LTR Site to another. The system equipment may be centrally located or distributed at each Site. A Site is a set of repeaters that are interconnected to pool the channels in a trunked channel group. 2000 Series OCXO Drawer with 1 OCXO - The OCXO (Oven Controlled Crystal Oscillator) drawer produces a stable 1.25 MHz (±0.1 PPM) reference signal for the Receiver and Exciter synthesizers. 2000 Series OCXO Drawer with 2 OCXOs - This OCXO drawer is the same a described above with the exception of a backup OCXO. 1.5 ACCESSORIES The accessories available for the Viking VX LTR repeater are listed in Table 1-1.

Refer to Figure 1-1. External Speaker Jack Power Indicator J104 provides repeater audio output to an external speaker. The local volume control adjusts the volume level of this speaker. CR501 indicates the +5V supply is at normal level and applied to the IAC. CR524 indicates -5V supply is at normal level and applied to the IAC. CR523 indicates the +15V accessory supply is at normal level. CR525 indicates that the +15V supply is at normal level and applied to the IAC. Speaker/Microphone Jacks J102 provides audio input from a microphone. J101 provides the receive audio to the microphone. CWID Indicator Local On/Off/Volume Control This indicates that the CW Identification is being transmitted on the lowest-frequency repeater. The CWID is a continuous-wave (CW) transmission of the station call letters in Morse Code to satisfy the station identification requirement. The CWID is programmed into the repeater memory. This indicator also is used when an alarm is transmitted with Morse code. R236 provides control of the receive audio output to J101 and J104. Turning this control clockwise past the detent applies voltage to the local audio amplifier. A D Level Test Point J100 provides audio/data level output for test level checks. Hang Indicator This indicates that the hang word is being transmitted by the repeater. This word is transmitted on calls in which the channel is held for the duration of the call and not just for the duration of the transmission. The hang word tells the mobiles to stay on the same channel and not re-access the system when responding to a call. Ground J103 is connected to ground for test equipment when monitoring test point J100. 1.12.3 INTERFACE ALARM CARD (IAC) Refer to Figure 1-1. Switch Call Indicator Voltage Test Output Not used in the LTR repeater. J502 provides a +15V test point on the IAC. Ground Mobile Call Indicator J501 is connected to ground for test equipment when monitoring voltage test point J502. Mobile-to-repeater transmission in progress is indicated by the Mobile Call Indicator. A D Level Test Point Xmit Indicator J500 provides a test point to monitor audio and data levels, AC fail and thermal sensor. This indicates that the repeater transmitter is keyed by the logic. 1-7 October 1999 Part No. 001-2009-201 INTRODUCTION AND OPERATION 1.12.4 POWER SUPPLY the mobiles in the system. Therefore, up to 1250 separate addresses can be assigned in a 5-repeater system and up to 5000 can be assigned in a 20-repeater system. An ID code may be assigned to an individual mobile or a group of mobiles as required. The 2000 Series Repeater Power Supply is a quad output 800W supply with power factor correction. A battery back-up module, PN 023-2000-830, can be added to the power supply to provide automatic battery revert in the event of AC power failure (see Section 2.4) The Battery Back-Up module charges the batteries when AC is present at the power supply (see Section 2.5 and 8.6). 1.13.3 INTER-REPEATER DATA COMMUNICATION Data communication between VIKING VX and LTR repeaters at a site is via a high-speed data bus. This bus cable is installed in a daisy-chain manner between repeaters. If both VIKING VX and LTR repeaters are located at a site, 20 repeaters can be interconnected. Refer to Section 2.9 for information on connecting the data bus. 1.13 REPEATER INFORMATION 1.13.1 INTRODUCTION NOTE: The VIKING VX does not require a separate LTR logic drawer. 1.13.4 MOBILE TRANSCEIVERS The repeater model used in an LTR system is determined by frequency range. 900 MHz systems use VIKING VX (-232/234) or LTR 8900s, UHF use 1010s, and VHF use 1100s. Repeaters operate on a single frequency (requires one repeater for each channel). The MPC in each repeater performs all control and signaling functions on that channel. Information is exchanged between repeaters via a high-speed data bus (modular cable). No system controller is required. The mobile and handheld transceivers used in an LTR system must be compatible with the type of signaling in use and also the frequency range. 1.14 REPEATER DATA BUS SIGNALING 1.14.1 GENERAL Optional accessories, such as the Telephone Interconnect Card (TIC) can be installed in the repeater and the ID Validator drawer can be installed in the repeater rack. Refer to Johnson LTR ID Validator Manual, Part No. 001-4408-501 and Johnson Telephone Interconnect Card Manual, Part No. 004-2000370 for detailed information. A single-line serial data bus interconnects the logic units of all the LTR repeaters at the site. The first repeater powered on generates the synchronization pulse that is used by all other repeaters to determine their time slot on the data bus. If all repeaters are powered on at the same time, the lowest numbered repeater generates the synchronization pulse. There are 21 slots with 1-20 used for repeater reporting and 21 used by the ID Validator (see Section 1.14.3). The time slot used by a repeater is determined by the number assigned to that repeater by the programming in the MPC. Repeater 1 uses time slot 1, repeater 5 uses time slot 5, and so on. The data rate on the repeater data bus is 18,750 bits per second. 1.13.2 HOME REPEATERS All mobiles have one of the site repeaters assigned as its "Home" repeater. This is the repeater from which it receives most of its control information. When a mobile is not placing or receiving a call, it is always monitoring its Home repeater to determine which channel is free and if it is being called by another mobile. In its time slot, each repeater places information on the data bus indicating its status. If a repeater is not busy, only start bits appear in its slot. If a repeater is busy, it places in its slot the Home repeater and ID code of the mobile receiving the call on that repeater. If a repeater number is unassigned, nothing appears in that time slot. The Home repeater is always used to make a call unless it is busy. When the Home repeater is busy, any other repeater in the site may then be used. Up to 250 ID codes are assigned to each repeater. An ID code and Home repeater number are the "address" of October 1999 Part No. 001-2009-201 1-8 INTRODUCTION AND OPERATION 1.14.2 MOBILE DATA MESSAGE ORDER 1.14.3 ID VALIDATOR OPERATION Each repeater monitors all the time slots on the repeater data bus. If it detects its number in another time slot, it begins transmitting an additional data message to its mobiles. This message tells mobiles programmed to detect that ID code to go to that repeater to receive a call. This additional message continues for as long as the mobile is transmitting on the other repeater. If the ID Validator is used, it is programmed with the status of up to all 5000 home repeater/ID code combinations possible with a 20-channel system. Each combination is programmed as either valid or invalid. Information in the twenty time slots on the repeater data bus is monitored. If an invalid home repeater/ID code combination is detected, the ID Validator places in time slot 21 the number of the repeater being used by the invalid mobile and also the ID code. When a repeater detects its number in slot 21, it transmits the turn-off code (31) to the mobile receiving the call. That mobile then squelches and resumes monitoring its home channel. This effectively disables the invalid mobile because it cannot talk to anyone. When the turn-off code is sent, the repeater places "21" in the repeater position of its time slot to indicate to the ID validator that turn-off has occurred. The sequence of data messages transmitted on a home repeater is as follows: Every third message is to the mobile currently receiving a call on that repeater. Then alternating between these messages are messages to its mobiles that have been trunked to other repeaters. For example, assume that five different mobiles on a five-repeater system are making calls. If all have Repeater 1 as their home channel (not very likely in actual practice), the data message order on Repeater 1 is as follows: 1 2 3 1 4 5 1 2 3 and so on. 1-9 October 1999 Part No. 001-2009-201 INTRODUCTION AND OPERATION October 1999 Part No. 001-2009-201 1-10 INTRODUCTION AND OPERATION SPECIFICATIONS GENERAL1 Frequency Range Dimensions AC Voltage/Frequency AC Current (at 117V AC) AC Input Power DC Current at 26.5V DC Number of Channels Channel Spacing Channel Resolution Temperature Range Duty Cycle FCC Type Acceptance FCC Compliance 896-901 MHz Receive, 935-940 MHz Transmit 9.125 H x 17" W x 20.9" D 100-240V AC/50-60 Hz 0.40A (Standby), 1.8A (25W), 3.3A (75W), 5.8A (160W) 47W (Standby), 211W (25W), 390W (75W), 680W (160W) 6A (25W), 11A (75W), 22.5A (160W) 1 (Synthesized, programmable) 12.5 kHz 12.5 kHz -30°C to +60°C (-22°F to +140°F) Continuous ATH2422009, ATH2422009-1 Parts 15, 90 RECEIVER 12 dB SINAD 20 dB Quieting Signal Displacement Bandwidth Adjacent Channel Rejection Intermodulation Rejection Spurious & Image Rejection Audio Squelch Sensitivity Audio Response Audio Distortion Local Audio Power Audio Sensitivity Hum & Noise Ratio Frequency Spread Frequency Stability 0.35 µV 0.50 µV ±3 kHz -75 dB -75 dB -90 dB 12 dB SINAD +1/-3 dB TIA Less than 3% at 0.5W/16 ohms 0.5W/16 ohms ±750 Hz -45 dB 5 MHz ±0.1 PPM -30°C to +60°C (-22°F to +140°F) TRANSMITTER RF Power Output Spurious Emissions Harmonic Emissions Audio Deviation LTR Data Deviation CWID Deviation Repeat Deviation Audio Response Audio Distortion Hum & Noise (TIA) Frequency Spread Frequency Stability Emission Designators Low Power = 75W min (default setting) 25W (variable set point) High Power = 160W min (default setting) 75W (variable set point) -90 dBc -90 dBc ±1.6 kHz ±750 Hz ±1 kHz ±800 Hz +1/-3 dB TIA Less than 2% -45 dB 5 MHz ±0.1 PPM -30°C to +60°C (-22°F to +140°F) 11K0F3E, 11K0F1D 1.

Information in this section tells how to set up the repeater for operation in an LTR system. It is assumed that the repeater has been previously aligned at the factory or as described in the alignment procedure in Section 7. 2.3 VENTILATION The RF modules and the power supply are equipped with fans, controlled by thermostats, that force air through the equipment for cooling. The air flow is from the front to the back of the equipment. This permits the Repeaters to be stacked or rack mounted (see Figure 2-3). There are a few considerations when installing Repeaters to provide adequate air circulation. Even though each repeater is thoroughly aligned and tested at the factory, it is good practice to check performance before it is placed in service. This ensures that no damage occurred during shipment and that the repeater is otherwise operating properly. Performance testing is described in Sections 7.2, 7.3, 7.4 and 7.5. • 2.1.1 SITE PREPARATION AND ANTENNA INSTALLATION Site preparation and antenna installation are not within the scope of this manual. Basic installation requirements are discussed in the "Dealer Guide To Site Preparation", Part No. 004-8000-100. Factory installation is also available. Contact your Johnson representative for more information. The Repeaters should be mounted with a minimum of 6 inches clearance between the front or back of the cabinet for air flow. The power supply requires a minimum of 18 inches at the back of the Repeater for removal. NOTE: Repeaters should not touch. Leave a minimum of one empty screw hole (approximately 1/2") between repeaters vertically, especially for bottom ventilation slots in high power repeaters. 2.2 ENVIRONMENT • Cabinet enclosures must provide air vents for adequate air circulation. • Temperature and humidity must be considered when several Repeaters are installed at a site. This might require air conditioning the site. The following conditions should be considered when selecting a site for the Repeater. Operating Temperature -30°C to +60°C (-22°F to +140°F). 2.4 AC POWER Humidity The AC power source to the Johnson VIKING VX Repeater can be 120V AC or 240V AC. Nothing need be done to the power supply for 240V AC operation. However, a 240V AC outlet requires that the 120V AC power plug be replaced. A locking AC power cord is provided for the supply. Less than 95% relative humidity at 50°C. Air Quality For equipment operating in a controlled environment with the Repeaters rack mounted, the airborne particles must not exceed 30 µg/m3. The 120V AC cord is a standard 3-wire grounded cord used with a standard AC wall outlet. The outlet must be capable of supplying a maximum of 328W (-232) or 680W (-234). With the nominal 120V AC input, the source must supply 3A for each 75W For equipment operating in an uncontrolled environment with the Repeaters rack mounted, the airborne particles must not exceed 100 µg/m3. 2-1 October 1999 Part No. 001-2009-201 INSTALLATION perature sensor connection is also provided. The temperature sensor cable is shown in Figure 2-2. LED indicators are provided to show Reverse Battery connection, Charger On/Off and Battery Fault. repeater or 6A for each 160W repeater and should be protected by a circuit breaker. It is recommended that all of the repeaters in a rack should not be on the same breaker in order to provide one operational repeater in the event a breaker trips. An AC surge protector is recommended for all equipment. TEMP WHT Each Repeater requires an outlet and the Receiver multicoupler and OCXO drawer require one each, so for a 5-channel system a minimum of 7 outlets is required. An additional three should be added for test equipment. The outlets must be within 3 feet of each Repeater cabinet. Future system expansion should be considered when electrical work is being planned for the initial system. NEGATIVE BATTERY TERMINAL Figure 2-2 TEMPERATURE SENSOR CABLE 2.6 800W POWER SUPPLY The VIKING VX Repeater power supply can be equipped with an optional 24V DC back-up in the event of AC power failure. Since the transmitter will remain on full power, if desired, the DC power source must have a current capability of about 15A per 75W repeater (25A per 160W repeater) or 75A for 5-75W repeaters (125A for 5-160W repeaters). The multicoupler requires another 1A for a total system requirement at 24V DC of 76.5A for 75W repeaters (126.5A for 160W repeaters). BREVERSE BATTERY EARTH GROUND B+ TEMP The power supply has four voltage output levels (see Table 2-1). Each voltage is set to ±1% at +25°C (+77°F). The output of this supply is capable or running any 2000 series repeater. Each output is overload protected such that the power supply current limits and automatically resets when the overload is removed (see Table 2-1). Each output is over voltage protected such that the power supply shuts down when an over voltage condition exists, usually when a component in the supply has failed (see Table 2-2). The power supply must be manually reset by toggling the Enable Line or removing AC power for more than 10 seconds.

The Power supply has the following safety agency approvals pending: UL1950, CSA22.2-950, TUV EN60950 (IEC950) 2.7 GROUNDING CAUTION PROPER SITE GROUNDING AND LIGHTNING PROTECTION ARE VERY IMPORTANT TO PREVENT PERMANENT DAMAGE TO THE REPEATER. When the AC input voltage is below 90V AC, the maximum output power is decreased to keep the input current constant. If a battery back-up is installed, the batteries take over when the AC input voltage falls below 80V AC (dependent on power output). As in any fixed radio installation, measures should be taken to reduce the possibility of lightning damage to the Viking VX equipment. Proper grounding eliminates shock hazard, protects against electromagnetic interference (EMI) and lightning. The AC input connector is an IEC connector equipped with a locking mechanism. 2-3 October 1999 Part No. 001-2009-201 INSTALLATION Ground each piece of equipment separately. Do not ground one piece of equipment by connecting it to another grounded piece of equipment. X= 1.05 1.09 1.13 1.17 1.20 1.30 A good DC ground must be found or created at the site. Rooftop site grounds can be researched through the building management or architects. Tower site grounds must be made with grounding rods. The many techniques for providing adequate grounds for towers and poles and for installing building ground bus lines are beyond the scope of this manual. Refer to National Electrical Code article 250 "Grounding Techniques," article 800 "Communications Systems" and follow local codes. for VSWR= 1.10 : 1 1.20 : 1 1.30 : 1 1.40 : 1 1.50 : 1 1.86 : 1 Example: Repeater power output of 60W with a VSWR of 1.3 : 1 (for this VSWR, X = 1.13): VP = 1.414 (1.13) (√60(50)) VP = 1.59782 (√60(50)) VP = 1.59782 (54.772256) VP = 87.52V The ground bus should be routed to the floor area within 5 feet of the system with a runner of 6 AWG or larger solid copper wire or 8 AWG stranded copper wire. Telephone Line There are four types of protection suppressors for telephone lines; Gas Tube, Silicon Avalanche Diode, Metal Oxide Varistor and Hybrid. The outer conductor of each transmission line at the point where it enters the building should be grounded using 6 AWG or larger solid copper wire or 8 AWG stranded wire. The hybrid protector is ideal for E.F. Johnson equipment, and is strongly recommended. A hybrid suppressor combines several forms of protection not available in just one type of device. For example, a high-speed diode reacts first clamping a voltage strike within 10 ns, a heavy duty heat coil reacts next to reduce the remainder of the current surge, and a highpowered three-element gas tube fires, grounding Tip and Ring. Secondary protection (other than grounding) provides the equipment protection against line transients that result from lightning. There are two types of secondary protection, RF and Telephone Line. Use the same wire sizes as specified for coaxial cables for any ground connections required by the secondary protectors. 2.7.1 PROTECTION GUIDELINES RF Follow these guidelines for grounding and lightning protection. Each Repeater installation site is different; all of these may not apply. An RF protector keeps any lightning strike to the antenna feed line or tower from damaging the Repeaters. Install this protection in-line with the combiner and antenna feed line. • Ensure that ground connections make good metalto-metal contact (grounding rod, grounding tray, metal conduit) using #6 gauge solid wire or braided wire straps. • With surge protectors, ensure that ground wires go directly to ground, and not through other equipment. • Run the ground wire for RF coax protectors directly to ground. • With coax protectors, ensure maximum instantaneous voltage does not exceed the rated voltage. RF protectors are selected by calculating the maximum instantaneous voltage at the output of the combiner. Do this by using the following equation. VP = 1.414 (X) (√P(50)) Where: VP = Voltage at the output of the combiner. P = repeater output in watts October 1999 Part No. 001-2009-201 2-4 INSTALLATION • Do not run ground wires parallel to any other wiring (e.g. a ground wire parallel to a telephone line), except other ground wires. • Double check all equipment for good ground and that all connections are clean and secure. 2.8 UNPACKING AND INSPECTION TM OCXO 1 OCXO2 E.F.

The MS-DOS Revision 2.0 or later operating system is needed to run the programs. The computer needs to have RS-232C capability, for example, the Serial Card in slot "COM1" or "COM2". The Johnson 2000 Repeater Program on 3.5 inch disk, Part No. 023-9998-297, uses an IBM personal computer to program the EEPROM Memory in the Main Processor Card (MPC). To lessen the chance of programming errors and simplify operation, the program uses yes/no questions or toggles through the available responses. 3.1.3 COMPUTER DESCRIPTION The programming software is designed to run on an IBM PC or compatible computer that meet the following minimum requirements. The computer is connected directly from the serial card to the MPC. The interconnect cables used are shown in Figure 4-28. The DB-9 to 8-pin modular adapter is connected to the serial port of the computer and an interconnect cable connects the adapter to the MPC. 1. One 3.5" high density disk drive. 2. 640K of memory 3. MS-DOS version 2.0 or higher NOTE: These connections are for the IBM computer and may differ from an IBM compatible. In which case, consult the manuals for your computer for serial card outputs and connections. 4. One serial port 5. Monochrome or color monitor and video card Although the program uses color to highlight certain areas on the screen, a monochrome (black and white) monitor or LCD laptop also provide satisfactory operation. Most video formats such as EGA and VGA are supported. A serial port is required to connect the Repeater to the computer. This port is standard with most computers. 3.1.1 HOW TO USE THIS MANUAL This manual introduces the program and illustrates how to use the features. This manual is organized to easily find programming information with the Table of Contents, Index and Parameter Tables for the responses required for programming. The cables from the Repeater to the computer are not included. With most computers, the adapter-tocomputer cable is a standard DB-25 M-F cable, PN 023-5800-017, (the male connector plugs into the adapter). If your computer requires a male connector, a male-to-male cable is also available, PN 023-5800016. The cable from the adapter to the Repeater has a modular-type 8-pin connector (see Figure 4-28). Graphic reproductions of the screens are shown for reference. Adjacent to the screens are tables to provide the parameters, available responses and a brief description of the parameter. It is not the intent of this manual to teach computer operation, but to allow the user to become familiar with the available screens and the responses without having to be at the computer. 3.1.4 EEPROM DATA STORAGE 3.1.2 GETTING STARTED The data programmed into the MPC is stored by an EEPROM Memory. Since this type of device is nonvolatile, data is stored indefinitely without the need for a constant power supply. A repeater can be removed from the site or even stored indefinitely without affecting programming. Since EEPROM Memory is also reprogrammable, a new device is not needed if programming is changed. NOTE: Before starting you should already know how to start MS-DOS, format and make backup copies of disks, copy and delete files, and run programs. If you are unfamiliar with any of these actions, refer to the MS-DOS manual for your computer for more information (see Section 5). 3-1 October 1999 Part No. 001-2009-201 SOFTWARE 3.1.5 COMMAND LINE OPTIONS 3.1.6 COLOR OR MONOCHROME OPERATION HELP The programming software utilizes color for a color monitor and video card. However, with LCDtype displays, this may make some information hard to read because the contrast is poor. To improve contrast, a monochrome mode can be selected in the display mode from Utilities heading. To show all options available from the command line type: /h or /?. Either ’/’ or ’-’ can be used. For example: 2000pgmr /h The options can be entered in any order. For example: 2000pgmr /d /b /c 3.2 REPEATER PROGRAM SOFTWARE 3.2.1 INSTALLING THE SOFTWARE When you receive the programming software, make a backup copy and store the master in a safe place. Copy the distribution disks using DOS DISKCOPY command. For example, type: COM PORT The Johnson programming software defaults to serial port COM1. However, if this port is already in use, the software can be reconfigured to use serial port COM2. To do this, use one of the following methods: DISKCOPY A: A: (single floppy drive) 1. When running the compiled (.EXE) version, type / c2 on the command line after the program name. For example: 2000pgmr /c2 or -c2 or 2. Select COM port from Utilities heading. If you have a hard disk drive, you may want to create one or more separate directories for transceiver programming and then transfer the program disk files to those directories. To create a new directory, use the MKDIR command. For example, to create directory RADIOPRG, type: DISKCOPY A: B: or C: (multi-drive systems). BAUD RATE The software defaults to 9600 baud, however this rate can be changed. To do this from the command line, type /bxxxx (xxxx = baud rate). For example: 2000pgmr /b or -b MKDIR \RADIOPRG. Then to make the new directory the current directory, use the CHDIR command. For example, to change to the \RADIOPRG directory, type NOTE: When the baud rate is changed on the command line, the baud rate jumpers on J3 in the MPC must also be changed to the same baud rate (see Section 6.11.8). CHDIR \RADIOPRG. To copy all files from a floppy disk in drive A: to this directory, type: DEMO MODE COPY A:*.* To view the screens for Read Setup Parms and Write Setup Parms from the Transfer menu when a repeater is not connected to the computer this option is used. Normally these screens are not available without a repeater connected. To do this from the command line, type: /d or -d. For example: 2000pgmr /d If you have a single floppy drive and no hard disk drive, you need to create programming disks. The reason for this is that there is not adequate space on the backup disk(s) for storing radio files. If your computer has dual floppy disk drives, the backup disk can be placed in one drive and then the radio files stored on a disk in the second drive. October 1999 Part No. 001-2009-201 3-2 SOFTWARE are also being loaded into conventional memory. Contact Customer Service for information on how these programs can be moved or disabled to make more space available. To make a programming disk, format a blank disk using FORMAT B: or FORMAT B: /S (use "/S" if it must be a bootable disk). Then copy the required program file or files to the programming disk. To do this, type COPY A:(filename.ext) B:(filename.ext). For example, to copy the file 2000pgm2.exe from drive A to drive B, type 3.3 REPEATER PROGRAMMER When the program is loaded into the computer and executed, the menu shows the files available from the directory. The program is used to create, edit, transfer and receive the repeater and channel parameters described in Section 5. COPY A:2000pgm2.exe B:2000pgm2.exe This procedure works for either single or dual drive computers. Refer to your computer reference manual for more information on these DOS commands. IMPORTANT The programming software is shipped in a compressed format. The name of the compressed file is 2000pgm2.exe and it extracts the following files so the program can be used on a PC. 2000PGMR.EXE 2000PGMR.HLP TESTM8L.HLP 2000PGMR.LNF TESTM8H.LNF TESTM8L.LNF TESTM9H.LNF TESTM9L.LNF TESTT8L.LNF TESTT9L.LNF The commands and displays referred to in this manual are for the IBM PC and may differ from IBM compatible. Refer to the computer’s operating system manual for command explanations. 441K 40K 1K 150K 10K 160K 10K 161K 52K 51K 3.3.1 PROGRAM FILES The files in the software directory are needed to run the program. 3.4 ALIGNMENT SOFTWARE The 2000PGMR2.EXE file is self extracting which means that the files extract automatically when executed. To extract these files so the program can be used, first make the current directory the destination directory for these files. For example, to make it the \RADIOPRG directory on drive C: (if not the current directory), type C: (Return) and then CD \RADIOPRG as just described. To make it the disk in drive B:, simply type B:. Then inset the program disk in drive A: and type A:2000PGM2 (or B: 2000PRM2 if drive B: is being used). The program files are automatically extracted into the current directory or disk. The software for the VIKING VX repeater programs the MPC to open and close the audio/data gates necessary for the alignment selected from the Test-Full Repeater menu. Under the menu heading Test are the alignment procedures for the PA (see Sections 7.4 and 7.5), Receiver (see Section 7.2), Exciter (see Section 7.3) and overall Full Repeater (see Section 7.6) including the MAC card (see Figure 3-1).

The filename for the repeaters in this file is shown in the lower left corner of the screen. CWID TIME 4.3.1 SETUP PARAMETERS CWID MESSAGE First see Section 4.3.4 to select repeater type to setup LTR Parameters. This menu programs the repeater parameters and options of each repeater at a site. Table 5-1 lists the parameters that are set by this screen (see Figure 5-1) and gives a brief description of each. FCC regulations require that the station call letters be transmitted periodically on the lowest- frequency repeater in the system and disabled on all the others. Morse code is used to encode these letters/ numbers for continuous-wave (CW) transmission (15 characters/numbers UPPER CASE). NOTE: The parameters are shown in the lower left of the pop-up screen for reference. LOCAL MIC ID This is the time interval between transmission of the CWID message (Disable, 1-60 minutes). The local microphone connected to the MAC jack is assigned a Group ID for transmitting when the local microphone PTT is active. This allows the Repeater to operate as a base station. REPEATER NUMBER Each repeater is programmed with a repeater number from 1-20. Make sure that this number agrees with the Home repeater number programmed in the mobiles assigned to this repeater. TEST MODE ID The Group ID that is transmitted when the Repeater is in the Test Mode. Mobiles with the same Group ID can communicate with the Repeater in the Test Mode (default for test mode is 254). CHANNEL NUMBER Each repeater is programmed with a channel number (1-399), see Appendix A. RF POWER LEVEL TELCO NETWORK TYPE This is the default power level. Enter the power level (25-75 or 75-160) that the repeater will use for transmit power. CIM to Repeater data signaling can be either FSK, RS-232, or FSK Blank and Burst. NOTE: This is not the actual power out level. Other factors must be considered for a true power. AREA This is the same as the area bit used when programming the mobiles. This bit is usually "0". POWER SOURCE SYNC REPEATER Indicates the primary type of power source to the Repeater (AC or DC). When AC is selected and Battery Backup is installed, the transmitter goes to half rated power (max.) in the event of AC failure. When DC is selected and AC fails, the power output is unchanged. None is used for LTR system repeaters. STAND ALONE Select if the repeater is not connected to additional repeaters via the high speed data bus. PAGING ID VALIDATOR This indicates if there is an optional paging terminal connected to the repeater. This option is not compatible with the LTR Data Modem, TIC, or VNC options.

A section of microstrip on the collector of Q201 and C205/C207 match the impedance from Q201 to the 3-pole helical filter L204-L206. 6.1.1 INTRODUCTION The receiver provides high sensitivity and selectivity reception on any one of the 399 channels in the 896 to 901 MHz band. 6.1.4 FIRST MIXER (U201), CRYSTAL FILTER (Z201/Z202) The receiver is a double conversion type with intermediate frequencies of 52.95 MHz and 450 kHz. The first injection frequency is stabilized by a temperature compensated crystal oscillator (TCXO) with a frequency stability of ±0.1 PPM from -30°C to +60°C (-22°F to +140° F). Two 3-pole bandpass filters in the front-end reject signals outside the receive band. Two 4-pole crystal filters and one 6-pole ceramic filter establish receiver selectivity (see block diagram Figure 6-1). First mixer U201 mixes the receive frequency with the first injection frequency to produce the 52.95 MHz first IF. Since low-side injection is used, the injection frequency is 52.95 MHz below the receive frequency. Matching between filter L204-L206 and the mixer is provided by L228, C208 and C372. The output of U201 is matched to Z201 at 52.95 MHz by L207, C209 and C267. Z201 and Z202 form a two-section, four-pole filter with a center frequency of 52.95 MHz and a -3 dB bandwidth of 8 kHz. This filter attenuates adjacent channels and other signals close to the receive frequency. The filter sections are a matched pair and the dot on the case indicates which leads connect together. Matching with Q202 is provided by C210, L209 and C270. 6.1.2 REGULATED VOLTAGE SUPPLIES The +15V DC power source is supplied by the repeater power supply. The +15V supply enters the receiver on J201, pin 1. U206 provides the +12V DC receive voltage to the RF and IF amplifiers. U210 supplies +12V DC to the first injection amplifiers. U207 supplies +12V DC to remaining +12V DC circuits. U208 supplies +6V DC to the remaining circuits. 6.1.5 IF AMPLIFIER (Q202), CRYSTAL FILTER (Z203/Z204) 6.1.3 HELICAL FILTER (L201-L203), RF AMPLIFIER (Q201) Q202 amplifies the 52.95 MHz IF signal to recover filter and mixer losses and improve receiver sensitivity. Biasing for Q202 is provided by R208/ R209/R211/R313 and C211/C212/C213 provide RF bypass. The output of Q202 is matched to crystal filter Z203 at 52.95 MHz by C214, C293 and L211. The receive signal enters the receiver on coaxial connector A201. A helical filter consisting of L201, L202 and L203 is a three-pole bandpass filter tuned to pass only a narrow band of frequencies (896-901 MHz) to the receiver. This filter also attenuates the image and other unwanted frequencies. Z203 and Z204 form a two-section, four-pole filter with a center frequency of 52.95 MHz and a -3 dB bandwidth of 8 kHz. This filter establishes the selectivity of the receiver by further filtering the 52.95 MHz IF. The filter sections are a matched pair and the dot on the case indicates which leads connect together. Matching with U202 is provided by C215, C216, C301, L225 and R322. Impedance matching between the helical filter and RF amplifier Q201 is provided by C201, C202 and a section of microstrip. Q201 amplifies the receive signal to recover filter losses and increases receiver sensitivity. Biasing for Q201 is provided by R201/ R202/R203/R204 and C204 provides RF bypass. A 1.8 dB attenuator follows amplifier Q201.

The 52.95 MHz IF signal is mixed with a 52.5 MHz signal produced by TCXO Y201 and tripler Q205. The 17.5 MHz (±0.1 PPM) output of Y201 is fed through C231 to tripler Q205. The tripler passes the third harmonic at 52.5 MHz to the OSC B input of U202.

RF choke L214 blocks the flow of RF through R229. An AC voltage divider formed by C236/C235 matches Q205 to the highpass filter. The third harmonic of the TCXO frequency is then used to drive the OSC B input at 52.5 MHz. L215, C237 and L216 form a high pass filter to attenuate frequencies below 52.95 MHz.

This programming is provided through J201, pins 18, 19 and 20. The frequency stability of the High Stability synthesizer (TCXO output) is established by the ±0.1 PPM stability of the OCXO drawer. The output from the high stability loop is stable from -40°C to +70°C (-40°F to +158°F). The phase detector in U205 compares the phase and frequency of two input signals; fR and fV. The phase detector generates a 0 to 5V signal. The pulse width of this signal varies depending on the phase difference between fR and fV. This signal is filtered (integrated) by C245/C246/C247/R245/R246 to provide a DC tuning voltage for the TCXO. The voltage at Y201, pin 2 is set for 3.5V when the high stability loop is locked. This is done by adjusting the tuning screw in TCXO Y201. The 450 kHz second IF is then fed to ceramic filter Z205, then to the IF amplifier. The center frequency of Z205 is 450 kHz with a -6 dB bandwidth of 9 kHz used to attenuate wideband noise. The limiter amplifies the 450 kHz signal 92 dB which removes any amplitude fluctuations. From the limiter, the signal is fed to the quadrature detector. An external phase-shift network connected to U202, pin 8, shifts the phase of one of the detector inputs 90° at 450 kHz (the other inputs are unshifted in phase). When modulation occurs, the frequency of the IF signal changes at an audio rate as does the phase of the shifted signal. The detector, which has no output with a 90° phase shift, converts the phase shift into an audio signal. Z213 is adjusted to provide maximum undistorted output from the detector. The audio signal is then fed out on U202, pin 9. 6.1.7 WIDEBAND AUDIO AMPLIFIER (U203B) One input signal to the phase detector in U205 is the reference frequency (fR). This frequency is 1.25 MHz divided by the R (reference) counter to 10 kHz. The 1.25 MHz signal comes from the OCXO drawer to J202. The signal is then fed to two buffer/amplifiers. Q203 provides the OCXO signal to the Receiver and Q204 provides the OCXO signal to the Exciter. The inputs to Q203/Q204 are matched to 50 ohms by R239/R321. DC blocking to Q203 is provided by C224. Bias for Q203 is provided by R219, R217, R218, R220 and R221. C313, C225 and C226 provide RF bypass. The output of Q203 is coupled to U205, pin 20 by C305. U203B amplifies the detected audio and data signal. R280/R263 set the gain of the amplifier and R256/R262/R284 provide a DC reference level. C220 bypasses the 450 kHz IF signal and C240 bypasses other frequencies. The output signal is adjusted by R264 and fed to J201, pin 9. 6.1.8 RSSI AMPLIFIER (U203A) U202, pin 13 is an output from an internal RSSI (receive signal strength indicator) circuit which provides a current proportional to the strength of the 450 kHz IF signal. The RSSI output is buffered through U203A and the level is adjusted by R261. The DC output signal is then fed to J201, pin 7. DC blocking to Q204 is provided by C227. Bias for Q204 is provided by R224/R222/R223/R225/ R226. C314, C228 and C229 provide RF bypass. The output of Q204 is coupled to the Exciter high stability synthesizer U401 by C230 (see Section 6.2.5). 6.1.9 HIGH STABILITY SYNTHESIZER (U205) The high stability synthesizer inputs/outputs are shown in Figures 6-1 and 6-3. The synthesizer contains the R (reference), N, and A counters, phase and lock detectors and counter programming circuitry. The phase detector output of Synthesizer U205, pin 6 is a 10 kHz pulse waveform from 0 to 5V. This signal is integrated to provide a DC tuning voltage for the TCXO. The DC tuning voltage provides the TCXO with the ±0.1 PPM stability of the OCXO (Oven Controlled Crystal Oscillator) see Section 6.3. The other input signal to the phase detector in U205 is from the TCXO frequency divided by the "N" counter and prescaler in U205. The "N" counter is programmed through the synthesizer data line on J201, pin 20. U205 is programmed so that the phase detector input (fV) is identical to the reference frequency (fR). The programming for the High Stability synthesizer does not change with channel selection. 6-3 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION DATA OUT REF in REF out CLOCK DATA IN ENABLE 20 PORT fR 13-STAGE R COUNTER OSC OR 4-STAGE DIVIDER OUTPUT A fV SHIFT REGISTER AND CONTROL LOGIC 19 16 LOGIC DOUBLE-BUFFERED R REGISTER 16 BITS 1 18 SELECT fR fV LOCK DETECT AND CONTROL C REGISTER 8 BITS 15 fR fV 17 STANDBY LOGIC 2 POR fR A REGISTER 24 BITS fV PHASE/FREQUENCY DETECTOR A AND CONTROL PHASE/FREQUENCY DETECTOR B AND CONTROL 8 6 3 4 LD OUTPUT B (OPEN-DRAIN OUTPUT) Rx PDout OR (UP) OV (DOWN) INTERNAL CONTROL 6-STAGE A COUNTER 12-STAGE N COUNTER MODULUS CONTROL LOGIC INPUT AMP f in f in 11 10 13 64/65 PRESCALER 9 TEST 2 TEST 1 Figure 6-3 SYNTHESIZER BLOCK DIAGRAM The programming of the counters in U205 is performed by circuitry in the Main Processor Card (MPC), buffered and latched through the Interface Alarm Card (IAC) and fed in to the synthesizer on J201, pin 20 to Data input port U205, pin 19. The fV input is produced by dividing the TCXO frequency using the prescaler and N counter in U205. The prescaler divides by 64 or 65. The divide number of the prescaler is controlled by the N and A counters in U205. Data is loaded into U205 serially on the Data input port U205, pin 19 when U205, pin 17 is low. Data is clocked into the shift registers a bit at a time by a low to high transition on the Clock input port U205, pin 18. The Clock pulses come from the MPC via the IAC to J201, pin 19. Both the N and A counters begin counting down from their programmed number. When the A counter reaches zero, it halts until the N counter reaches zero. Both counters then reset and the cycle repeats. The A counter is always programmed with a smaller number than the N counter. While the A counter is counting down, the prescaler divides by 65. Then when the A counter is halted, the prescaler divides by 64. As an example: To produce the frequency of 10 kHz, the N and A counters are programmed as follows: The counter divide numbers are chosen so the TCXO-derived input to the phase detector (fV) is the same frequency as the OCXO-derived input (fR). The fR input is produced by dividing the 1.25 MHz OCXO frequency by 125. This produces a reference frequency (fR) of 10 kHz. October 1999 Part No. 001-2009-201 N = 27 6-4 A = 22 CIRCUIT DESCRIPTION R806 and R807. AC voltage divider C812 and C813 initiates and maintains oscillation. C803 couples Q802 to resonator L220 that provides the shunt inductance of the tank circuit. The shunt capacitance of the tank circuit is made primarily by C804 in series with CR802. To determine the overall divide number of the prescaler and N counter, the number of TCXO output pulses required to produce one N counter output pulse can be counted. The prescaler divides by 65 for 65 x 22 or 1430 input pulses. It then divides by 64 for 64 x (27 - 22) or 320 input pulses. The overall divide number K is therefore (320 + 1430) or 1750. The TCXO frequency of 17.5000 MHz divided by 1750 equals 10 kHz which is the fR input to the phase detector. The overall divide number K can also be determined by the formula: The VCO frequency is controlled by a DC voltage across varactor diode CR802. As voltage across a reverse-biased varactor diode increases, its capacitance decreases. Therefore, VCO frequency increases as the control voltage increases. The control line is RF isolated from tank circuit by choke L804. The amount of frequency change produced by CR802 is controlled by series capacitor C804. K = 64N + A Where, N = N counter divide number A = A counter divide number. 6.1.10 LOCK DETECT 6.1.13 ACTIVE FILTER When the synthesizer is locked on frequency, the Lock Detect output on U205, pin 2 is a logic high voltage with narrow negative-going pulses. When the synthesizer is unlocked, the negative- going pulses are much wider, the width may vary at a rate determined by the frequency difference of fV and fR. The lock detect pulses are applied to J201, pin 19 and sent to the RF Interface on J102, pin 19 for detection and sampling in the IAC. Q801 functions as a capacitance multiplier to provide filtering of the 12V supply to Q802. R801 and R802 provide transistor bias, and C809 provides the capacitance that is effectively multiplied by the gain of Q801. If a noise pulse or other voltage change appears on the collector, the base voltage does not change because of C809. Therefore, the base current does not change and transistor current remains constant. R803 decouples the VCO output from AC ground. L803 is an RF choke and C807, C808, C810 and C811 provide RF bypass. 6.1.11 BUFFER AMPLIFIER (Q206, Q207) A cascode amplifier formed by Q206 and Q207 provides amplification and also isolation between the TCXO and Synthesizer U205. A cascode amplifier is used because it provides high reverse isolation. The input signal to this amplifier is from TCXO Y201. C250 provides DC blocking. Bias for the amplifier is provided by R241, R242, R243, R244 and R240. L217 is an RF choke. RF bypass is provided by C244, C249 and C248. The output of Q206/Q207 is coupled to U205 by C306 6.1.14 BUFFER (Q208, Q209) A cascode amplifier formed by Q208/Q209 provides amplification and isolation between the VCO and synthesizer. A cascode amplifier is used because it provides high gain, high isolation and consumes only a small amount of power. The input signal to this amplifier is coupled from the VCO RF output on pin 4. DC blocking to the VCO is provided by C268 and to the buffer by C261. Bias for the amplifier is provided by R275, R279, R278 and R277. Q209 is a common-emitter amplifier and Q208 is a commonbase with C260 providing RF bypass. L219 provides some filtering of the cascode output. R273 lowers the Q of L219. The output of the amplifier is coupled by C309 to U209, pin 11. 6.1.12 VCO (A006) The Voltage-Controlled Oscillator (VCO) is formed by Q802 circuitry and a resonator consisting of L220 in the Receiver. The adjusting screw in L220 tunes the tank circuit to the desired frequency range. The VCO oscillates in a frequency range from 843848 MHz. Biasing of Q802 is provided by R805, 6-5 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION 6.1.15 SYNTHESIZER (U209) sor Card (MPC), which is buffered and latched through the Interface Alarm Card (IAC) and fed into the synthesizer on J201, pin 20 to Data input port U209, pin 19. The synthesizer inputs/outputs are shown in Figures 6-1 and 6-3. The synthesizer output signal is the receiver first injection frequency. This signal is produced by a VCO (voltage-controller oscillator). The frequency of this oscillator is controlled by a DC voltage. This DC voltage is generated by integrating the pulses from the phase detector in synthesizer chip U209. This integration is performed by the synthesizer loop filter which is made up of C805, C806 and R804 in the VCO circuitry. Data is loaded into U209 serially on the Data input port U209, pin 19. Data is clocked into the shift registers a bit at a time by a low to high transition on the Clock input port U209, pin 18. The Clock pulses come from the MPC via the IAC to J201, pin 18. As previously stated, the counter divide numbers are chosen so that when the VCO is operating on the correct frequency, the VCO-derived input to the phase detector (fV) is the same frequency as the TCXOderived input (fR) which is 12.5 kHz. Frequencies are selected by programming counters in U209 to divide by a certain number. This programming is provided through J201, pins 12, 18 and 20. The frequency stability of the synthesizer is established by the ±0.1 PPM stability of the high stability synthesizer loop consisting of OCXO, Synthesizer U205, Y201 and Q206/Q207. The output from the high stability loop is stable from -40°C to +70°C (40°F to +158°F). The fR input is produced by dividing the 17.5 MHz TCXO frequency by 1400. This division is done by the "R" counter in U209. The counter always divides by 1400 regardless of the channel number. This produces a reference frequency (fR) of 12.5 kHz. Since the VCO is on frequency (receive frequency minus 52.95 MHz) and no multiplication is used, the channel frequencies change in 12.5 kHz steps and the reference frequency (fR) is 12.5 kHz for all channels selected by this receiver. The VCO frequency of A006 is controlled by a DC voltage produced by integrating the phase detector output pulses of U209. The phase detector senses the phase and frequency of two input signals (fR and fV) and causes the VCO control voltage to increase or decrease if they are not the same. When the frequencies are the same the VCO is "locked" on frequency. The fV input is produced by dividing the VCO frequency using the prescaler and N counter in U209. The prescaler divides by 64 or 65. The divide number of the prescaler is controlled by the N and A counters in U209. One input signal to the phase detector in U209 is the reference frequency (fR). This is the 17.5 MHz TCXO frequency divided by the R (reference) counter to the channel spacing or 12.5 kHz. The N and A counters function as follows: both the N and A counters begin counting down from their programmed number. When the A counter reaches zero, it halts until the N counter reaches zero. Both counters then reset and the cycle repeats. The A counter is always programmed with a smaller number than the N counter. While the A counter is counting down, the prescaler divides by 65. Then when the A counter is halted, the prescaler divides by 64. The other input signal to the phase detector in U209 is from the VCO frequency divided down by the "N" counter and prescaler in synthesizer U209 to 12.5 kHz. The "N" counter is programmed through the synthesizer data line on J201, pin 20. U209 is programmed so that the phase detector input (fV) is identical to the reference frequency (fR) (12.5 kHz) when the VCO is locked on the correct frequency. Example: Assume a receive frequency of 898.5000 MHz (channel 200). Since the VCO is 52.95 MHz below the receive frequency it must be 845.5500 MHz for channel 200. To produce this frequency, the N and A counters are programmed as follows: N = 1056 A = 60 The synthesizer contains the R (reference), N, and A counters, phase and lock detectors and counter programming circuitry. Frequencies are selected by programming the three counters in U209 to divide by assigned numbers. The programming of these counters is performed by circuitry in the Main ProcesOctober 1999 Part No. 001-2009-201 6-6 CIRCUIT DESCRIPTION 6.1.18 BUFFER AMPLIFIER (Q214, Q215) NOTE: Section 8.2.5 describes how the N and A counter numbers are calculated for other channels. A cascode amplifier formed by Q214 and Q215 provides amplification and also isolation between the VCO and Receiver RF stages. A cascode amplifier is used because it provides high reverse isolation. The input signal to this amplifier is coupled from VCO A006 by C268. C268 also provides DC blocking. Bias for the amplifier is provided by R294, R311, R290, R291 and R292. L222 is an RF choke and R293 lowers the Q of the coil. RF bypass is provided by C274, C356, C310, C272, C273 and C335. The output of Q214/Q215 is matched to the Receiver RF stages by C275, C276 and two sections of microstrip. To determine the overall divide number of the prescaler and N counter, the number of VCO output pulses required to produce one N counter output pulse can be counted. In this example, the prescaler divides by 65 for 65 x 60 or 3,900 input pulses. It then divides by 64 for 64 x (1056 - 60) or 63,744 input pulses. The overall divide number K is therefore (3,900 + 63,744) or 67,644. The VCO frequency of 845.5500 MHz divided by 67,644 equals 12.5 kHz which is the fR input to the phase detector. The overall divide number K can also be determined by the following formula: K = 64N + A 6.1.19 RF AMPLIFIERS (Q216, Q217) U210 provides the +12V source for these amplifiers. RF amplifier Q216 is biased by R296 and R295. C278 provides RF bypass from the DC line and R297 provides supply voltage isolation. A section of microstrip on the collector acts as an RF inductor. Q216 is matched to Q217 by C277, C263, C288 and two sections of microstrip. Where, N = N counter divide number and A = A counter divide number. 6.1.16 BUFFER AMPLIFIER (Q210, Q211) A cascode amplifier formed by Q210 and Q211 provides amplification and also isolation between the TCXO and Synthesizer U209. A cascode amplifier is used because it provides high reverse isolation. The input signal to this amplifier is from TCXO Y201. C254 provides DC blocking. Bias for the amplifier is provided by R312, R248, R249, R251 and R250. L218 is an RF choke. RF bypass is provided by C251, C252 and C253. The output of Q210/Q211 is coupled to U209 by C307. RF amplifier/buffer Q217 is similar in design to Q216. The output of Q217 is matched to the 3 dB attenuator made up of R285/R286/R287 by two sections of microstrip and C280 provides DC blocking. L223/L224 are tuned to the receive frequency -52.95 MHz and passed to Mixer U201. This injection frequency is also coupled through C284 to U204A. CR201, R255, R254 provide DC input to U204A, pin 3. The output of U204A, pin 1 is connected to J201, pin 13 for a receive injection test point and connected to the RF Interface Board on J103, pin 13. 6.1.17 LOCK DETECT 6.2 EXCITER When the synthesizer is locked on frequency, the Lock Detect on U209, pin 2 is a high voltage with very narrow negative-going pulses. Then when the synthesizer is unlocked, these pulses become much wider, the width may vary at a rate determined by the frequency difference of fV and fR. 6.2.1 VCO (A007) The Voltage-Controlled Oscillator (VCO) is formed by Q802, associated circuitry and a resonator consisting of L404 in the Exciter. The screw in L404 tunes the tank circuit to the desired frequency range. The VCO oscillates in a frequency range from 935940 MHz. Biasing of Q802 is provided by R805, R806 and R807. An AC voltage divider formed by C812 and C813 initiates and maintains oscillation. C803 couples Q802 to resonator L404 in the Exciter. The lock detect pulses are filtered by R270/C325 and applied to J201, pin 14 and the RF Interface on J103, pin 14 for detection and sampling in the IAC. 6-7 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION amplifier U129B and transmit modulation gate U118D to P100, pin 29 (Tx MOD). P100, pin 29 is connected to backplane connector J2, pin 8 and RFIB connector J101, pin 22 to J102, pin 13. The transmit modulation and 3.5V reference enter the Exciter on J401, pin 13 and is routed to U402B,pin 6. R425 sets the TCXO modulation level. The modulation signal along with the 3.5V DC is applied to U402A, pin 2. Resonator L404 provides the shunt inductance of the tank circuit. The shunt capacitance of the tank circuit is made primarily of C804 in series with CR802. RF choke L805 completes the DC bias path to ground. The VCO frequency is controlled in part by DC voltage across varactor diode CR802. As voltage across a reverse-biased varactor diode increases, its capacitance decreases. Therefore, VCO frequency increases as the control voltage increases. The control line is RF isolated from tank circuit by choke L804. The amount of frequency change produced by CR802 is controlled by series capacitor C804. 6.2.3 ACTIVE FILTER Q801 functions as a capacitance multiplier to provide filtering of the 12V supply to Q802. R801 and R802 provide transistor bias, and C809 provides capacitance that is effectively multiplied by the gain of Q801. If a noise pulse or other quick voltage change appears on the collector, base voltage does not change significantly because of C809. Therefore, the base current does not change and transistor current remains constant. R803 decouples the VCO output from AC ground. L803 is an RF choke and C807/ C808/C810/C811 provide RF bypass. The frequency is modulated in a similar manner. The transmit audio/data signal is applied across varactor diode CR801 to vary the VCO frequency at an audio rate. C802 in series with CR801 determine the amount of modulation produced by the audio signal. 6.2.2 EXCITER VCO AND TCXO FREQUENCY MODULATION 6.2.4 BUFFER (Q406, Q407) Both the VCO and TCXO are modulated in order to achieve the required frequency response. If only the VCO was modulated, the phase detector in U403 would sense the frequency change and increase or decrease the VCO control voltage to counteract the change (at the lower audio frequencies inside the closed loop bandwidth of the synthesizer). If only the TCXO frequency was modulated, the VCO would not track the higher audio frequencies (those beyond the closed loop bandwidth of the synthesizer). However, by modulating both the VCO and TCXO a flat audio response is achieved. Potentiometers R425 and R446 balance the modulating signals. A cascode amplifier formed by Q406/Q407 provides amplification and isolation between the VCO and synthesizer. A cascode amplifier is used because it provides high reverse isolation. The input signal to this amplifier is tapped from the VCO RF output. DC blocking and coupling to the VCO is provided by C441 and to the buffer by C433. Bias for the amplifier is provided by R451, R453, R454 and R455. Q407 is a common-emitter amplifier and Q406 is a common-base with C432 providing RF bypass. L403 decouples the output from AC ground and R452 lowers the Q of L403. The amplifier is coupled by C429 and C499 to U403, pin 11. There are two 3.5V sources on the Exciter board; one is a reference for the modulation amplifier to the VCO, the other is for the modulation amplifier to the TCXO. 6.2.5 HIGH STABILITY SYNTHESIZER (U401) The High Stability synthesizer inputs/outputs are shown in Figures 6-3 and 6-4. The synthesizer contains the R (reference), N, and A counters, phase and lock detectors and counter programming circuitry. The phase detector output signal of Synthesizer U401, pin 6 is a 10 kHz pulse waveform from 0 to 5V. This signal is integrated to provide a DC tuning voltage for the TCXO. The DC tuning voltage provides the TCXO with the ±0.1 PPM stability of the OCXO (see Section 6.3). The reference voltage on U402B, pin 5 is sent to buffer U407B, J401, pin 9 to RFIB connector J102, pin 9 and out on J101, pin 14 to J2, pin 27 on the backplane, to the bottom connectors via pin 7 and finally to the MAC on P100, pin 7. With reference to the ground on the Exciter, the 3.5V reference stability is maintained by U126B/C/D on the MAC. The 3.5V DC passes through summing October 1999 Part No. 001-2009-201 6-8 CIRCUIT DESCRIPTION The fV input is produced by dividing the TCXO frequency using the prescaler and N counter in U401. The prescaler divides by 64 or 65. The prescaler divide number is controlled by the N and A counters in U401. The N and A counters function as follows: The phase detector output signal is generated by counters in U401 programmed to divide by a certain number. This programming is provided through J401, pins 18, 19 and 20. The frequency stability of the High Stability synthesizer is established by the ±0.1 PPM stability of the OCXO, stable from -40°C to +70°C (-40°F to +158°F). Both the N and A counters begin counting down from their programmed number. When the A counter reaches zero, it halts until the N counter reaches zero. Both counters then reset and the cycle repeats. The A counter is always programmed with a smaller number than the N counter. While the A counter is counting down, the prescaler divides by 65. Then when the A counter is halted, the prescaler divides by 64. The phase detector in U401 compares the phase and frequency of two input signals; fR and fV. The phase detector generates a 0 to 5V signal. The pulse width of this signal varies depending on the phase difference between fR and fV. This signal is filtered (integrated) by C406/C407/C408/R411/R412 to provide a DC tuning voltage for the TCXO. The voltage at U402A, pin 1 is set for 3.5V when the high stability loop is locked. This is done by adjusting the tuning screw in TCXO Y401. Example: To produce the 10 kHz frequency, the N and A counters are programmed as follows: N = 27 One input signal is the reference frequency (fR). This frequency is the 1.25 MHz OCXO frequency divided by the reference counter to 10 kHz. A = 22 To determine the overall divide number of the prescaler and N counter, the number of TCXO output pulses required to produce one N counter output pulse can be counted. In this example, the prescaler divides by 65 for 65 x 22 or 1430 input pulses. It then divides by 64 for 64 x (27 - 22) or 320 input pulses. The overall divide number K is therefore (320 + 1430) or 1750. The TCXO frequency of 17.5000 MHz divided by 1750 equals 10 kHz which is the fR input to the phase detector. The overall divide number K can also be determined by the following formula: The other input signal to the phase detector in U401 is from the TCXO frequency divided by the "N" counter and prescaler in U401. The N counter is programmed through the synthesizer data line on J401, pin 20. U401 is programmed so the phase detector input (fV) is identical to the reference frequency (fR). High Stability synthesizer programming does not change with channel selection. K = 64N + A The programming of the counters in U401 is performed by circuitry in the Main Processor Card (MPC), buffered and latched through the Interface Alarm Card (IAC) and fed in to the synthesizer on J401, pin 20 to Data input port U401, pin 19. Where, N = N counter divide number and A = A counter divide number. Data is loaded into U401 serially on the Data input port U401, pin 19 when U401, pin 17 is low. Data is clocked into the shift registers a bit at a time by a low to high transition on the Clock input port U401, pin 18. The Clock pulses come from the MPC via the IAC to J401, pin 19. 6.2.6 LOCK DETECT When the synthesizer is locked on frequency, the Lock Detect output on U401, pin 2 is a logic high voltage with narrow negative-going pulses. When the synthesizer is unlocked, the negative- going pulses are much wider, the width may vary at a rate determined by the frequency difference of fV and fR. The lock detect pulses of U401 are filtered by R407/C401 and applied to J401, pin 17, then sent to the RFIB on J102, pin 17 for detection. As stated, the counter divide numbers are chosen so the TCXO derived input to the phase detector (fV) is the same frequency as the OCXO derived input (fR). The fR input is produced by dividing the 1.25 MHz OCXO frequency by 125 to produce a reference frequency (fR) of 10 kHz. 6-9 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION HIGH STABILITY SYNTHESIZER BUFFER HS CS EX HS LK EX REF IN Q401/Q402 U401 F IN TX OCXO FROM Q204 PD OUT SWITCH LPTT Q405 AMP EX MOD TCXO BUFFER U402B U402A AMP BUFFER U404A U404B MAIN SYNTHESIZER DATA CLK SYN CS EX PD OUT U403 F IN Y401 VCO A007 Q410/Q411 Q412 Q413 BUFFER BUFFER AMP AMP Q406/Q407 U407B TO PA V REF EX BUFFER SYN LK EX REF IN Q403/Q404 Figure 6-4 EXCITER BLOCK DIAGRAM 6.2.7 BUFFER AMPLIFIER (Q401, Q402) (voltage-controller oscillator) that is frequency controlled by a DC voltage produced by synthesizer chip U403. This DC voltage is filtered by a loop filter made up of C805, C806 and R804 in the VCO circuitry. A cascode amplifier formed by Q401 and Q402 provides amplification and also isolation between the TCXO and Synthesizer U401. A cascode amplifier is used because it provides high gain, high isolation and consumes only a small amount of power. The input signal to this amplifier is coupled from TCXO Y401, pin 5 by C415. C415 also provides DC blocking. Bias for the amplifier is provided by R420, R421, R422, R423 and R418. L401 is an RF choke. RF bypass is provided by C411, C413 and C414. The output of Q401/Q402 is coupled to U401, pin 11 by C412. Frequencies are selected by programming counters in U403 to divide by a certain number. This programming is provided through J401, pins 12, 19 and 20. The frequency stability of the synthesizer is established by the ±0.1 PPM stability of the high stability loop that is stable from -40°C to +70°C (-40°F to +158°F). The VCO frequency of A007 is controlled by a DC voltage produced by integrating the phase detector output pulses of U403. The phase detector senses the phase and frequency of two input signals and causes the VCO control voltage to increase or decrease if they are not the same. When the frequencies are the same, the VCO is then "locked" on frequency. 6.2.8 EXCITER SYNTHESIZER (U403) The synthesizer inputs/outputs are shown in Figures 6-3 and 6-4. The synthesizer output signal is the transmit frequency. This signal is produced by a VCO October 1999 Part No. 001-2009-201 6-10 CIRCUIT DESCRIPTION The synthesizer contains the R (reference), N, and A counters, phase and lock detectors and counter programming circuitry. Both the N and A counters begin counting down from their programmed number. When the A counter reaches zero, it halts until the N counter reaches zero. Both counters then reset and the cycle repeats. The A counter is always programmed with a smaller number than the N counter. While the A counter is counting down, the prescaler divides by 65. Then when the A counter is halted, the prescaler divides by 64. One input signal to the phase detector in U403 is the reference frequency (fR). This frequency is the 17.5 MHz TCXO frequency divided by the reference counter to the channel spacing or 12.5 kHz. The other input signal (fV) is the VCO frequency divided by the prescaler and the "N" counter in U403. The counters are programmed through the synthesizer data line on J401, pin 20. Each channel is programmed by a divide number so the phase detector input is identical to the reference frequency (fR) when the VCO is locked on the correct frequency. Example: To illustrate the operation of these counters, assume a transmit frequency of 937.5000 MHz (channel 200). Since the VCO is on the channel transmit frequency, this frequency is used. To produce this frequency, the N and A counters are programmed as follows: N = 1171 Frequencies are selected by programming the three counters in U403 to divide by assigned number. The programming of these counters is performed by circuitry in the Main Processor Card (MPC), buffered and latched through the Interface Alarm Card (IAC) and fed in to the synthesizer on J401, pin 20 to Data input port U403, pin 19. A = 56 To determine the overall divide number of the prescaler and N counter, the number of VCO output pulses required to produce one N counter output pulse can be counted. In this example, the prescaler divides by 65 for 65 x 56 or 3640 input pulses. It then divides by 64 for 64 x (1171 - 56) or 71,360 input pulses. The overall divide number K is therefore (71,360 + 3640) or 75,000. The VCO frequency of 937.5000 MHz divided by 75,000 equals 12.5 kHz which is the fR input to the phase detector. The overall divide number K can also be determined by the following formula: Data is loaded into U403 serially on the Data input port U403, pin 19 when U403, pin 17 is low. Data is clocked into the shift registers a bit at a time by a low to high transition on the Clock input port U403, pin 18. The Clock pulses come from the MPC via the IAC to J401, pin 19. K = 64N + A As previously stated, the counter divide numbers are chosen so that when the VCO is operating on the correct frequency, the VCO-derived input to the phase detector (fV) is the same frequency as the TCXOderived input (fR). The fR input is produced by dividing the 17.5 MHz TCXO frequency by 1187. The R counter divides by 1187 regardless of the channel number. This produces a reference frequency (fR) of 12.5 kHz. Since the VCO is on frequency and no multiplication is used, channel frequencies change in 12.5 kHz steps. The reference frequency is 12.5 kHz for all channels selected by this Exciter. Where, N = N counter divide number and A = A counter divide number. NOTE: Section 8.2.5 describes how the N and A counter numbers can be calculated for other channels. 6.2.9 BUFFER AMPLIFIER (Q403, Q404) A cascode amplifier formed by Q403 and Q404 provides amplification and also isolation between the TCXO and Synthesizer U403. A cascode amplifier is used because it provides high gain, high reverse isolation and consumes only a small amount of power. The input signal to this amplifier is coupled from TCXO Y401, pin 5 by C420. C420 also provides DC blocking. Bias for the amplifier is provided by R430, R431, R432, R433 and R428. L402 is an RF choke. RF The fV input is produced by dividing the VCO frequency using the prescaler and N counter in U403. The prescaler divides by 64 or 65. The divide number of the prescaler is controlled by the N and A counters in U403. The N and A counters function as follows: 6-11 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION 6.2.13 RF AMPLIFIERS (Q412, Q413) bypass is provided by C416, C418 and C419. The output of Q403/Q404 is coupled to U403, pin 20 by C417. RF amplifier Q412 is biased by CR402, R469, R470 and R472. C448 provides RF bypass from the DC line and R471/R472 provide supply voltage isolation. A section of microstrip on the collector acts as an RF choke to the supply line. Q412 is matched to Q413 by C449, C451 and two sections of microstrip. 6.2.10 BUFFER AMPLIFIER (Q406, Q407) A cascode amplifier formed by Q406 and Q407 provides amplification and also isolation between the VCO and Synthesizer U403. A cascode amplifier is used because it provides high gain, high isolation and consumes only a small amount of power. The input signal to this amplifier is coupled from VCO A007, pin 6 by C433. C433 also provides DC blocking. Bias for the amplifier is provided by R450, R451, R453, R454 and R455. L403 is an RF choke. RF bypass is provided by C430, C431 and C479. The output of Q406/Q407 is coupled to U403, pin 11 by a non-polarized capacitor formed by C429/C499. RF amplifier/buffer Q413 is similar in design to Q412. The collector voltage of Q413 is switched by Q405. The Logic Push-To-Talk (LPTT) on J401, pin 11 turns on Q405 and conducts the 15V supply to the collector of Q405 and to Q413. The output of Q413 is matched to 50 ohms by two sections of microstrip and C465 that also provides DC blocking. A 3 dB attenuator follows amplifier Q413. The RF output of the Exciter is on coaxial connector J402 to the Power Amplifier. 6.2.11 LOCK DETECT 6.3 OCXO DRAWER When the synthesizer is locked on frequency, the Lock Detect output on U403, pin 2 is a high voltage with narrow negative-going pulses. When the synthesizer is unlocked, the negative-going pulses are much wider, the width may vary at a rate determined by the frequency difference of fV and fR. 6.3.1 INTRODUCTION The OCXO (Oven Controlled Crystal Oscillator) drawer produces the 1.25 MHz reference signal input for the high stability synthesizer loops of both the Receiver and Exciter. One OCXO drawer alone can drive eight repeaters. More repeaters can be driven with the use of external rack mounted 8-Way splitters. The signal level at each of the eight outputs is high enough to allow splitting the signal through an additional 8-Way splitter to drive additional repeaters. The locked or unlocked condition of the synthesizer is filtered by R440/C423 and applied to J401, pin 16, then sent to the RF Interface on J102, pin 16 for detection. 6.2.12 BUFFER AMPLIFIER (Q410, Q411) The OCXOs generate a 10 MHz signal. The frequency stability of these oscillators is better than 0.1 PPM from -40°C to +70°C (-40°F to +158°F). One half hour after a cold start (at room temperature), the oscillators will be within 1E-8 of their stabilized frequency. Two OCXOs are used for redundancy. The drawer can be configured so that either oscillator is main and the remaining oscillator will be standby. If the main oscillator has an output failure, the drawer will automatically switch to the standby oscillator to drive the outputs. The oscillators can be switched between main and standby remotely. The drawer will not allow remote switching of oscillators if either oscillator has an output failure. A cascode amplifier formed by Q410/Q411 provides amplification and also isolation between the VCO and exciter RF stages. A cascode amplifier is used because it provides high gain, high isolation and consumes only a small amount of power. The input signal to this amplifier is coupled from VCO A007, pin 4 by C441. C441 also provides DC blocking. Bias for the amplifier is provided by R464, R465, R466, R467 and R468. L406 is an RF choke and R463 lowers the Q of the coil. RF bypass is provided by C434, C442, C445, C443, C444 and C480. The output of Q410/Q411 is matched to the Exciter RF stages by C446, R450 and two sections of microstrip.

The internal 15V DC supply is powered from a 120V (±10%) or 240V (±10%) AC line. When both supplies are present, the internal 15V DC supply powers the drawer and the external 15V DC supply is a backup. If the internal supply should fail, the external 15V DC supply powers the drawer. The current requirement of the drawer is less than 1A upon initial turn on, and reduces to approximately 630 mA after the oscillators are stabilized. The OCXO drawer contains several alarms. For all alarms, the following color scheme applies (see Figure 6-6): Flashing Red Yellow Green Failure Standby Active (OK) If the main oscillator fails, its corresponding LED turns from green (active) to flashing red (failure). Consequently the LED for the remaining oscillator changes from yellow (standby) to green (active). 6-13 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION 10 MHz IN OUT ALLOW 30 MINUTES WARM UP FOR PROPER STABILIZATION 1.25 MHz OUTPUTS 115V 1 2 3 4 5 6 7 8 9 10 11 12 1314 15 16 1718 BACK PANEL TM OCXO1 OCXO2 DELTA F OUTPUT AC DC DC BACKUP INTERRUPT OCXO 1 INTERRUPT OCXO 2 INTERRUPT FRONT PANEL Figure 6-6 OCXO DRAWER FRONT/REAR PANELS When there is no output from the drawer, the RF Output LED changes from green to flashing red indicating failure. of the oscillators as described in Section 6.3.1 is accomplished by the logic gates U901-U904. The 10 MHz signal is then applied to the counter chip U905. U905 is used to divide the 10 MHz signal by eight to create 1.25 MHz. When there is a difference of more than 10 Hz between the two 10 MHz oscillators, the Delta F LED changes from green to flashing red (failure). The dual line driver chip U906 is used to drive the 8-Way 1.25 MHz outputs and the 10 MHz output. The signal is filtered to remove harmonics. The 1.25 MHz outputs have approximately 0 dBm of power into 50 ohms. The 10 MHz output delivers about 10 dBm into 50 ohms. The Delta F alarm circuit has built in hysteresis and will not return to green until there is less than 5 Hz difference between the 10 MHz oscillators. When both supplies are present, the AC LED is green (active), and the DC LED is yellow (standby). If the AC supply fails, the AC LED changes to flashing red (failure) and the DC LED changes to green (active) indicating that it is now powering the OCXO drawer. If the external DC supply fails, the DC LED changes from yellow (standby) to flashing red (failure). 6.3.3 OCXO SWITCHING (U901A-D, U902A-D, U903D, U904A/D) Refer to the OCXO switching circuitry in Figure 6-7. The circuit is broken down into three levels where various tasks are performed. The bottom section is for remote control input and selecting which OCXO LED should indicate standby. U902A, pins 12 (OSC 1 - OSC 2) come from the OCXO pulse detector circuits. A logic high on U902A, pin 1 (OSC 1) indicates that OCXO 1 has output. Likewise, a logic high on U902A, pin 2 (OSC 2) indicates that OCXO 2 has output. All of these alarms are tied to relays that can be set to open or close contacts upon alarms. The relay contacts are connected to the 18-pin connector at the rear of the drawer. These relay contacts are capable of handling 1A DC current. 6.3.2 OCXOS, BUFFERS , DIVIDER AND LINE DRIVER NOTE: U902C, pin 8 (S) cannot be high unless both OCXO pulse detectors indicate output. Therefore, no remote switching of OCXOs is allowed unless both OCXOs are running. The OCXOs produce a signal level greater than 1V RMS. Q901 and Q902 serve as buffers and square up the signal from 0 to 5V (see Figure 6-5).

In this section, an Exclusive OR logic decision is made between inputs (S) and (OSC 1). When U902B, pin 6 (X) is high, OCXO 1 is selected, when it is low, OCXO 2 is selected. If (OSC 1) is low, (X) goes low and OCXO 2 is selected. Relay driver Q908 can be driven by either Q2 or Q2 depending on the desired normal state of the OCXO 1 alarm relay. U911, pins 1-2 also serve as a pulse detector for OCXO 2. NOTE: The bottom circuit does not allow (S) to be high and (OSC 1) to be low. If (OSC 1) is high and (S) is low, (X) stays high, and OCXO 1 is selected as the main oscillator. Finally, if (OSC 1) is high and (S) is high, (X) goes low and OCXO 2 is selected as the main oscillator. The Delta F detection circuitry is made up of U910, U911 and U913. The buffered output of OCXO 2 is applied to the D-input of flip-flop U910 and the buffered output of OCXO 1 is applied to the CLKinput. The Q-output is the frequency difference between the two OCXOs. 6.3.4 OCXO PULSE DETECTION The Q-output of U910, pin 5 is applied to the trigger input (B2) of the one-shot multivibrator in U911, pin 10. This device produces a 5 ms negative-going pulse when it is triggered. It is triggered twice by every output cycle from U910, pin 5. The second triggering is caused by the undetermined states produced when the signal goes low at the half-cycle point. Because of this double triggering, the frequency on the Q2 output of U911, pin 12 is twice the frequency difference of the two OCXOs. 6.3.5 DELTA F DETECTION (U910, U911, U913) The buffered OCXO 1 signal is sent to U907, pins 9-10. U907 is a retriggerable one-shot multivibrator that is used for pulse detection. If four or more 10 MHz pulses from OCXO 1 are missing, the output of one-shot multivibrator Q2 goes low. This turns off LED driver Q905 and the green half of LED DS902 turns off. Simultaneously, Q2 goes high. This pulses on/off Q907 and strobes the red fail LED for OCXO 1. 6-15 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION Power control is connected to WO505 from the RF Interface board (RFIB). RF is filtered from the control voltage line by various capacitors and inductors to U501, pin 2. This control voltage regulates the RF output of the amplifier on U501, pin 4 to approximately 5W. The Q2 output of U911, pin 12 is applied to U913, pin 14, which is one input of an internal phase comparator. The other input of this phase comparator is from a voltage controlled oscillator (VCO) internal to U913. The output of this phase comparator at U911, pin 13 is essentially low if the input from the VCO is higher in frequency than the input from U911, pin 12. Conversely, this output is essentially high if the input from the VCO is lower in frequency than the input from U911, pin 12. Clocking pulses are continually present on the PCP output of U913, pin 1. 6.4.2 DRIVER (Q501) The output of U501 passes through several sections of 50 ohm microstrip and matching capacitors to the emitter of Q501. Driver Q501 is a common- base amplifier with a normal output of approximately 22W. Supply voltage is RF bypassed by various capacitors and microstrip. C525/C526/C536/ C537/C538/C589 match the output of the driver to the input impedance of the combiner to the final amplifiers. The VCO oscillates at either the high or low end of its operating range, depending on the logic level present on the control input of U913, pin 9. If the control input is high, it oscillates at the high end of its range. If the control input is low, it oscillates at the low end of its range. The high frequency is approximately 20 Hz and the low frequency is approximately 10 Hz. During normal operation, the Q output of the flip-flop in U910, pin 8 is high and the VCO oscillates at 20 Hz. 6.4.3 FINAL AMPLIFIERS (Q502, Q503) When the frequency difference between OCXOs exceeds about 10 Hz (1 PPM), the frequency of the signal from U911, pin 12 exceeds the VCO frequency. Recall that the frequency difference is doubled by U911. The output from the phase comparator on U913, pin 13 goes high and the Q outputs of flipflop U910B change state. This turns on red LED DS904. The Q output of U910, pin 9 now applies a logic low to the VCO control input of U913, pin 9 and the VCO goes to its low frequency limit (10 Hz). Therefore, the OCXO frequency difference must decrease to less than 5 Hz for the alarm to be canceled. This hysteresis prevents intermittent triggering when the frequency difference is near the triggering point. Q502 and Q503 are combined 60W amplifiers. A 50 ohm microstrip connects the RF to a 70.7 ohm Wilkinson splitter and then to the emitter of each common-base amplifier. The 60W outputs on the collectors of the amplifiers are combined using a Wilkinson combiner. Q502 has a half-wave transmission line on the input and Q503 has a half-wave on the output. These transmission lines are used to drive the 60W amplifiers out of phase. The output of the combiner is fed from WO513 directly to the forward/reverse power detect board. The Wilkinson splitter and combiner provide the capability to split the drive input and combine the final outputs while maintaining isolation between the two final amplifiers. The combiner consists of two quarter-wave transmission lines and a balancing resistor. During normal operation, signals of relatively equal phase and amplitude are present on both ends of the balancing resistor. Therefore, no current flows and no power is dissipated in the balance resistor. If one final fails, the other final of the pair continues to function. 6.4 75W POWER AMPLIFIER 6.4.1 AMPLIFIER/PRE-DRIVER (U501) RF input to the PA from the Exciter is through a coaxial cable and connector to WO511. C501 couples the RF to 50 ohm microstrip that connects the input to U501. U501 is a 6W amplifier/pre- driver operating in the 935-940 MHz band.

R663 and R680 are used to calibrate the forward and reflected power. Electromagnetic coupling is used to sample the output of each final amplifier. The RF is then fed to a rectifier to create a voltage indicative of the power output. The outputs of CR502 (W510) and CR503 (W508) are monitored by the repeater software through the RF Interface Board. If a final amplifier fails, the software reduces the output power to prevent overdriving the remaining final amplifier. 6.5 160W POWER AMPLIFIER 6.5.1 GAIN BLOCK (Q501 AND U501) RF input to the PA from the Exciter is through a coaxial cable and connected to WO509. The signal coming through WO509 is amplified to approximately 0.25W using Q501 and associated matching components. This signal is then fed into U501. U501 is an 18W amplifier/pre-driver operating in the 935940 MHz range. 6.4.5 THERMAL SENSOR (U503) Thermal protection is provided by temperature sensor U503. The operating range of the sensor is from -0° C to +100° C (+32° F to 212° F). Amplifier U502A sends the output of U503 through WO509 to the RF Interface Board. The RF Interface Board uses the temperature sensor signal to turn the fan on (50°C) and off (45°C). If the temperature of the heatsink exceeds 90°C power is reduced 3 dB. When the heatsink exceeds 95°C the RF is shut down. Power control is connected to WO505 from the RF Interface board (RFIB). RF is filtered from the control voltage line by various capacitors and inductors to U501, pin 2. This control voltage regulates the RF output of the amplifier on U501, pin 5 to approximately 15W (see Figure 6-9). 6.4.6 FORWARD/REVERSE POWER DETECT, CIRCULATOR, LOW-PASS FILTER 6.5.2 DRIVER (Q502) The output of U501 passes through several sections of 50 ohm microstrip and matching capacitors to the emitter of Q502. Driver Q502 is a common base amplifier with an output of approximately 60W. Supply voltage is RF bypassed by various capacitors and microstrip. C568 matches the output of the driver to the input impedance of the splitter to the final amplifiers. The power amplifier output is directly coupled to the forward/reverse power detect board via a jumper. The output then enters the circulator and exits to the low-pass filter board and the antenna jack for a minimum power output of 75W at the default setting. If an antenna is not connected, the circulator connects the output power to R685. 6-17 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION POWER SENSE RF 1 SPLITTER 1/2 WAVE DELAY LINE COMBINER Q701 Q702 COMBINER LOW-PASS FILTER POWER SENSE RF 2 SPLITTER RF OUTPUT RF IN GAIN BLOCK DRIVER U501 Q502 Q501 1/4 WAVE TRANSFORMER DIRECTIONAL COUPLER POWER CONTROL RF 3 THERMAL SENSOR RF 4 RF LOAD CIRCULATOR POWER SENSE U651A/B SPLITTER AMP THERMAL SENSOR U502A U503 FORWARD Q703 Q704 U652A/B VSWR 1/2 WAVE DELAY COMBINER POWER SENSE Figure 6-9 160W PA BLOCK DIAGRAM 6.5.3 FINAL AMPLIFIERS (Q701, Q702, Q703, Q704) resistor. Therefore, no current flows and no power is dissipated in the resistor. If one final fails, the other final of the pair would continue to function. The output of the driver is DC blocked by C552 and is connected to the first 70.7 ohm splitter with a 50 ohm microstrip. One output of the first splitter is sent directly to another 70.7 ohm splitter to feed Q703/Q704. The second output is connected to the splitter driving Q701/Q702 through a half-wave 50 ohm microstrip. The 60W output of Q701/Q702 is combined through a 70.7 ohm quarter-wave Wilkinson combiner and fed through a 50 ohm microstrip to the final 50 ohm combiner. 6.5.4 POWER DETECTORS Electromagnetic coupling is used to detect the output of each final amplifier. The detected RF is then fed to a rectifier to create a voltage output indication of the power output. The outputs are monitored by the RFIB and the station software. If any of the finals fails, the software will reduce the output power to prevent overdriving the remaining final amplifier. 6.5.5 FORWARD/REVERSE POWER DETECT, CIRCULATOR, LOW-PASS FILTER Outputs from amplifiers Q703/Q704 are fed to the final combiner through 50 ohm microstrip that is a half-wavelength longer than the other side. The 25 ohm output impedance of the final combiner is transformed to 50 ohms through a quarter-wave, 35.35 ohm microstrip. The output of the quarter-wave transformer is fed directly into the forward power detector via W510. The power amplifier output is directly coupled to the forward/reverse power detect board via a jumper. The output then enters the circulator and exits to the low-pass filter board and the antenna jack for a power output of 160W (±7W). If an antenna is not connected, the circulator connects the output to R685. The Wilkinson combiners provide the capability to split the drive input and combine the final outputs while maintaining isolation between the final amplifiers. Each combiner consists of two quarter- wave transmission lines and a balancing resistor.

R663 and R680 are used to calibrate the forward and reverse sense levels. The sensed levels are connected to the RF Interface Board and software. 6-18 CIRCUIT DESCRIPTION 6.6 RF INTERFACE BOARD Pin 4 The RF Interface Board connects the Receiver, Exciter and Power Amplifier to the backplane and power supply (see Figure 6-10). Pin 4 carries ground current between the RF Interface board and Backplane board. The input and output connectors for the RF Interface Board are defined as follows. 6.6.1 POWER CONNECTOR GROUND Pins 5-6 UNUSED Pin 7 RX WBAND The wide band audio is from the receive audio demodulator U202 and goes to the MAC in the Controller card cage. The typical amplitude is 387 mV RMS (-6 dBm) and 2V DC with Standard TIA Test Modulation into the receiver. Little wave shaping is done on the receiver board other than a 31 kHz RC LPF which strips off the 450 kHz IF. Buffering is done with an op-amp. The power supply is connected to the RF Interface Board when the RF module is inserted into the station cabinet (see Figure 10-7). The jack portion of the connection is on the RF Interface Board, the plug portion is attached to the repeater cabinet.

The resistor network connected to CR104 charges up C106/C107 to +18V off the line. This provides the bias voltage required to start the controller IC U102. Once the IC turns on current is being switched on L107. A small tap winding on L107 provides sustaining current to the U102. When AC is first connected it could take several seconds for C106/C107 to charge to +14V before the unit starts. WARNING This power supply contains voltage potentials greater than 400V. Considering the dangerous voltages and the complexity of the switch-mode power supply, it is strongly recommended the power supply be returned to E.F. Johnson for repair (see Section 1.7). U102 samples the input voltage through R105/ R106/R107; the input current through R113/R114; and the output voltage through the divider at R127. U102 modulates the duty cycle to MOSFET Q101 such that the input current is shaped like and in phase with the input voltage. The controller has two feedback loops; a voltage loop to keep the 400V constant and a current loop to keep input current correct. Compensation for the current error amp is C120/R141/C121 on U102, pin 1. Compensation for the voltage error amp is provided by C127/C142/C126 on U102, pin 16. U102, pin 4 and associated circuitry automatically adjust the Power Factor Correction (PFC) for input voltage (100240V AC), line frequency (50-60 Hz) and load on the power factor. 6.7.1 FILTER BOARD AC power is brought into the power supply through the IEC connector in the front of the power supply (see Figure 2-7). This connector is attached to the EMI filter assembly, Part No. 023-2000-820. The filter contains common mode and differential mode filtering such that the supply complies with FCC Class-A regulations. In addition to the filter components (C1, C2, L1, C3, C4, L2, C5) R1 is used to discharge the filter capacitors when AC is removed. Metal-oxide varistors (RV001/RV002) are placed across the line on the input and output of the EMI filter that clamp transients on the AC line to prevent damage to the power supply. The AC power is fused with F001 after the connector and before the filter. Replace fuse with a 15A/250V (314015) fuse. NOTE: The output voltage of the power factor section is at 400V DC. This voltage is bled off slowly. After turning off, it can take more than 5 minutes to discharge. 6.7.3 MAIN PULSE WIDTH MODULATOR At the output of the filter board is a bridge rectifier. The rectifier is heat sunk to the filter bracket through a Grafoil thermal interface pad. Filtered AC power is connected to the main board via wires W001 and W003. Filter and rectified current is brought to the main board via wires W004 and W005. The safety ground is connected from the filter board to a stud in the chassis through W002. The +26.5V output is created from a two-transistor forward converter Q116/Q118. It uses the 400V output of the power factor correction on C110/C111 for an input voltage. The same controller IC (U102) drives the +26.5V stage. This stage runs at exactly twice the power factor correction frequency and uses trailing edge modulation. The pulse width modulator uses the PFC supplied current for modulation scheme that reduces ripple current in C110/C111. 6.7.2 POWER FACTOR CORRECTION The output of the IC, U102, pin 11 is fed to a level shifting gate drive network comprised of C139, C140, T106, C136, C197, C137 and C228. Each MOSFET (Q116, Q118) of the two-transistor forward converter has a gate protection zener diode CR117, CR120 respectively. In addition, each power MOSFET has a gate turnoff network. The power factor switching frequency is set at 87.5 kHz, ±5 kHz. The average current mode boost converter is comprised of L107, Q101, CR145, C110, C111. Half of U102 is used for power factor correction. RT101/RT102 are negative temperature coefficient thermistors that limit the in-rush current to C110/ October 1999 Part No. 001-2009-201 6-26 6-27 AC SENSE AC IN DC IN T101 RT101, RT102 Q104 VCC CR110, CR111 CR101, CR102 BRIDGE RECTIFIER TEMP +5V REGULATOR SENSOR U106 U101 TO REMOTE EN Q103 Q105, Q106 U107 AMP U110A TEMP OUT U110C T105 CURRENT SENSE U115 FAN CONTROLLER Q120, Q121 U110D OVERVOLTAGE SHUTDOWN FAN SYNC L101 BUFFER/ HYSTERESIS Q114 2-TRANSISTOR HI/LO VOLTAGE FWD CONVERTER ISOLATION Q115, Q116 T106 Q117, Q118 RESISTOR LADDER THERMAL SHUTDOWN T106 U109 LEVEL SHIFTING GATE DRIVE ON/OFF SENSE BATT BACK-UP +6 to +18V U108 PWM OUT Q101 VOLTAGE SENSE Q108 Q107 VDC RAMP I SENSE FB PFC U102 IAC CURRENT MODE BOOST CONVERTER L107 T103 T104 EXT IN +26.5V DC U111 CT RAMP/ISD Q122, Q123 Q124, Q125 +5V TO U104 CT U114 VCC OUT BUCK BOOST CONVERTER Q129, Q130 Q131, Q132 BUCK CONVERTER OUT RAMP/ISD EA OUT/INV U113 CONTROLLER U104A/B Q110, Q111, Q112 -5V DC OUT T109 T108 Q127 Q128 SAWTOOTH BUFFER BUCK CONVERTER OUT +15V DC +5V REG U105 +26.5V +15V U112 VREF CONTROLLER L104 L102 +15V DC OUT UNDER VOLTAGE PROTECTION U118, Q138 U122 U117, Q133 U120 OVER VOLTAGE PROTECTION +5V DC OUT OVER VOLTAGE PROTECTION U116, Q126 U119 L103 CIRCUIT DESCRIPTION Figure 6-11 BLOCK DIAGRAM October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION converters, the cycle terminates and a new one starts. This forces the +15V and +5V converters to run at the same frequency and is slightly delayed from the +26.5V converter. In operation, the power MOSFETs Q116, Q118 are on for approximately one-third of the period providing current to the primary side of T107. During that time CR121 is forward conducting and charging L101. When the MOSFETs are switched off, the magnetizing current of T107 continues to flow through CR118, CR119. These diodes place 400V across the transformer in opposite polarity that resets the transformer core. During the off period CR128 is free wheeling and L101 is discharging. Transformer T107 provides the isolation between the low voltage and high voltage sections. 6.7.5 FAN AND THERMAL SHUTDOWN The voltage supply to the thermal measurement circuit is generated from transformer T101 and the associated bridge rectifier consisting of CR101, CR102, CR110 and CR111 and bulk storage capacitor C101. This voltage is approximately +9V when the AC voltage is at 120V AC. The +26.5V pulse width modulator is peak current mode controlled. This type of converter requires current and voltage sense. T105, CR112, R125, R146 and C125 provide the current sense circuit. The voltage sense circuit is U109 and the associated circuitry on the isolated side of the supply. NOTE: This DC voltage is dependant on the input AC voltage. U106 provides a very accurate +5V required for proper operation of the temperature sense circuit. A precision temperature sensor (U101) is mounted to the +26.5V rectifier heatsink. The output of this sensor is 10 mV/°C with a ±1% accuracy. This voltage is amplified by U110A with precision resistors R183/ R184 setting the gain. An opto-isolator is used to cross the boundary from high to low voltage sections. In the event of an over-voltage condition (>+32V) U115 and associated components turn the power supply off. This shutdown mechanism latches the power supply Off. The enable line must be turned Off for 10 seconds for the power supply to reset. T106 has a tap to provide current to the optional battery back-up (Part No. 023-2000-830). The +26.5V is available at the high current output connector to the power supply and it also powers the +15V, +5V and -5V converters through F102. The output of gain stage U110A is fed to the computer interface via WO116 to monitor power supply temperature with the programmer. The output of U110A, pin 3 is also connected to the thermal shutdown circuit U110C, R135, R136, R137, R138 and R139. If the heatsink temperature reaches 92°C (198°F) the output of U110C, pin 8 goes high and saturates Q103. When Q103 is turned on U107 is turned off and the power supply turns off. The remote voltage is always present so when the heatsink temperature drops to 80°C (176°F) the power supply restarts. The high temperature condition would only exist if the fan was blocked or faulty. 6.7.4 SYNCHRONIZING CIRCUITS The +15V and +5V sections run at the same frequency as the +26.5V pulse width modulator. In order for a beat note not to be produced, a sync circuit is used. If two converters are not synchronized, the difference frequency may show up at an undesired location in the repeater. The output of U110A, pin 1 also connects to the fan controller. U110D with the associated resistors provides a means to turn the fan on/off. Transistors Q120/Q121 provide current gain and a voltage level shift to run the fan. The fan turns on when the heatsink reaches approximately 45°C (113°F) and turns off again when the temperature reaches 35°C (95°C). In normal operation the fan turns on and off. Divider R151/R152 samples the output of the main pulse width modulator. When Q116 and Q118 turn on, the output on U104A, pin 3 goes high. C138, R176, CR122 along with U104B creates a very narrow pulse on U104B, pin 6. Q110, Q111 and Q112 level shift and buffer this pulse. When the narrow pulse is presented to the timing capacitor of the +15V and +5V October 1999 Part No. 001-2009-201 6-28 CIRCUIT DESCRIPTION 6.7.6 +15V CONVERTER Sync pulse is added into the low side of C176 via C172 and R225. The free running frequency of the 15V converter (approximately 145 kHz) is set about 10% lower than the 26.5V converter. This longer duty cycle allows the sync circuit to synchronize the converter. The input voltage to this "Buck" DC/DC converter is the main +26.5V output fused through F102. The bias voltage for the controller IC U112, pin 15 is provided by a +15V regulator U111. The basic buck converter consists of MOSFET Q125, Schottky diode CR126 and storage inductor L102. C165, C166, C167, L103, C169 and C170 filter the output voltage and attenuate the ripple at the switching frequency (160 kHz). The capacitors are an integral part of the feedback loop. The duty cycle is approximately 60%. Over voltage is sensed using U116 as a reference and amplifier, CR129 acts as a crowbar on the output. Once the crowbar is turned on, opto-isolator U119 is activated to shutdown the power supply. The enable line must be toggled or AC voltage removed for 10 seconds to reset the power supply. The +15V buck converter is peak current mode controlled. T108 samples the inductor current while MOSFET Q125 is on. The sampled current is translated to a voltage via CR127, R209 and R210. 6.7.7 +5V CONVERTER Operation of the +5V "Buck" DC/DC converter is the same as the +15V, except slop compensation is not required. Some values are different to get the 5.2V DC and current limit to 6A. The duty cycle is approximately 20%. Because the MOSFET is a high-side switch, a charge pump is required to get the gate voltage above the input voltage. The charge pump operates as follows. When the output from IC U112, pin 14 is low, capacitor C162 is charged through CR124, R198, R199, R200 and Q122/Q123 are off. When U112, pin 14 goes high, the capacitor stays charged and CR124 is reverse biased. Q122/Q123 are turned on forward biasing CR125 and applying a gate-to-source voltage of approximately +12V. During this time Q124 is off. When U112, pin 14 goes low, Q124 turns on and rapidly discharges the gate capacitance. 6.7.8 -5V CONVERTER The -5V "Buck-Boost" converter scales and inverts the voltage. This converter is free running at approximately 75 kHz. The output switch and controller are built into the 5-leg TO-220 IC U114. L105 is the storage inductor. C204, R270 and R271 close the voltage feedback loop and are set for optimum stable transient response. C208/C209 reduce output ripple. Under-voltage protection is required on this stage and works the same as the over-voltage protection of the +15V and +5V buck converters, but has opposite polarity. Resistors R231/R208 coupled with C164 provide snubbing for Schottky diode CR126. Because the +15V converter operates at greater than 50% duty cycle, slope compensation is required. Capacitor C176 is the time capacitor for this converter and R223 is the resistor that sets the charge current. A sawtooth wave is present on the high side of C176 that is buffered by Q127/Q128. The resistor divider network of R315, R227, R229 and R232 provide the correct amount of compensation for stable operation and current limiting. 6.7.9 POWER SUPPLY REPAIR AND ALIGNMENT If a power supply fails it is typically a Power MOSFET or Power Diode. In some cases the MOSFET gate may short and cause some of the driver circuits to be damaged. When replacing heat sunk components it is advisable to replace the sil-pad thermal interface material at the same time. The mounting hardware must be replaced exactly as built in the factory. The mounting screws for the power semiconductors MUST BE torqued to 4-5 in/lbs. Under torque and over torque can shorten the life of the semiconductor. The output voltage is sampled by R215, R216 and R217 and sent to the inverting side of the error amplifier internal to the controller IC on U112, pin 1. Voltage loop compensation is set by C174, C175 and R221. 6-29 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION 6.8.2 CHARGER The majority of the voltage and current limits are set with fixed value components in the power supply. However, the +26.5V, +15V and +5.2V supplies are adjustable. When certain components are replaced, the voltages must be adjusted. The voltages should be set at light load (i.e. repeater in the Receive mode). The charger charges the batteries when the repeater is on and switch S101 is "on". A tap off of the main transformer of the power supply through wire W104 and a +26.5V line via wire W102 are what supply the charger with the necessary voltage to charge the batteries. The tap off of the transformer is biased by the +26.5V and then filtered through L101, C105 and C119. Since the tap from the power supply is not a regulated voltage, bleeder resistors R136/R137 dissipate some power when the batteries are fully charged. No load situation, the peak voltage of the tap is approximately 63V, is not impressed across the 50V capacitors C105/C119. During a battery charging condition the line voltage to the charger on U107, pin 2 should be about 35V. 1. The +26.5V supply can be adjusted with R174 when any of the following components are replaced: R173, R174, R175, U109, U108, U102, R143, R170 or R171. 2. The +15V supply can be adjusted with R216 when any of the following components are replaced: R215, R216, R217 or U112. 3. The +5.2V supply can be adjusted with R254 when any of the following components are replaced: R253, R254, R255 or U113. While charging batteries, if the charge voltage is varied with respect to the temperature of the batteries, the lifetime of the batteries is increased dramatically. Figure 6-12 shows the algorithm used in float charge applications for two 12V lead-acid batteries in series. Figure 6-12 shows that the charge voltage should be 27.3V DC ±0.15V at 25°C (77°F) with -55 mV/°C temperature compensation. 6.8 BATTERY BACK-UP MODULE 6.8.1 OPERATION When a battery back-up module is installed in a power supply it performs the function of running a repeater in the absence of AC voltage. When AC is present it can be used to charge a pair of lead-acid batteries in series. The charger is a temperature compensated constant voltage charger. The maximum output current from the charger is 2.2A. The charger works when AC is present and the repeater is enabled. The charger switch on the battery back-up module must be "On". The temperature compensation thermal sensor is part of 023-2000-223 battery back-up module cable assembly. An LM317M linear voltage regulator (U107) is used to create the temperature compensated charge voltage. This device is capable of delivering 2.2A of continuous current to the batteries. To create a temperature compensated voltage an op amp (U104) is used as a voltage gain device from a temperature probe attached to the batteries (part of 023-2000-223). This op amp with R148/R149 defines the slope for the algorithm of Figure 6-12. The output of the temperature compensation is attached to the adjust pin of U107. R138-R140 allow the output voltage to be set properly at a given ambient temperature. F101 is a 4A resettable fuse used to prevent thermal run away in the event of U107 failure. If the output current to the batteries exceeds 4A this fuse opens. Once the current drops below 100 mA, the fuse closes automatically. When AC is low or not applied to the 023-2000800 power supply the battery input takes over if the voltage is within range. The input voltage to the battery back-up module acts as the 26.5V supply and the other voltages in the power supply also are present, +15, +5.2 and -5V. When AC is restored, the battery back-up module disengages automatically. The change over from battery to AC or AC to battery may cause the repeater to reset, depending on battery condition and load status. NOTE: If any of the charging components are replaced, R140 needs to be adjusted to set the output (battery back-up battery terminals) voltage to 27.3V ±0.15V when temperature sensor is at 22°C (71.6°F). NOTE: When using a generator, the DC voltage must be between 23-28.5V (26.5V DC is recommended) and ripple voltage less than 1% or approximately 0.25V P-P. October 1999 Part No. 001-2009-201 6-30 CIRCUIT DESCRIPTION 6.8.4 ENGAGING THE RELAY Charger Voltage The main purpose of the Battery Back-Up Module (BBM) is that when the power supply loses AC line voltage, a pair of series connected 12V lead acid batteries (approximately 26.4V) or other 23-28.5V DC source will engage to the supply allowing the repeater to operate. To perform this function a voltage comparator (U101) is used to monitor the charge tap coming from the power supply. 30V -55mV/°C 27.3V 25.2V 24V -30° 0° +22° +30° A 2.5V reference voltage is supplied to the comparator from U102. The transformer tap voltage is smoothed and divided by CR114, C118, R116, R121 and R122. The values for these components were calculated so that when the AC line voltage is dropped to 70V AC, the output of the comparator turns Q103/ Q102 on which in turn engages the relay K101. The relay is capable of 30A which delivers the battery energy to the power supply via W102 with the return line being W103. Temp (°C) +60° Figure 6-12 NO LOAD CHARGE VOLTAGE vs. TEMPERATURE 6.8.3 REVERSE BATTERY PROTECTION NOTE: When AC is restored, the relay disengages and the charger automatically begins to charge the batteries. To obtain reverse battery protection a number of techniques were implemented. Q108/Q110 are arranged in a Darlington configuration to isolate the output capacitors C109-C111 from conducting in the event the batteries are connected backwards. This circuit also provides a means to turn the battery charger off in case the user wants to run the repeater off of another DC source. S101 opens the base of Q105 which turns off Q104. CR111 is a green light emitting diode (LED) located on the right hand side of the battery back-up module when looking at the front of the power supply that tells the user the charger is in charge mode and is marked "On". 6.8.5 OVER/UNDERVOLTAGE SHUTDOWN U101 is a quad comparator IC used to create the overvoltage and undervoltage shutdown circuitry. If the batteries are drained sufficiently enough such that the voltage of the batteries drops below 20.3V DC the output of the comparator goes low and turns Q102 off. By turning Q102 off the batteries are switched out of the circuit. The batteries cannot be switched back into the repeater until the voltage rises to 22.6V DC. This operation is in place to protect the repeater and the batteries. In the event the batteries are over charged, or the repeater is driven by the generator that has the voltage set too high, the relay will disengage above 30.5V DC. In order to switch the batteries back to the repeater, the voltage must drop below 29V DC. To notify the user that the batteries are connected improperly R101/CR101 are connected in series across the batteries. CR101 is a red LED that lights when the batteries are connected backwards and is located on the left hand side of the battery back-up module when looking at the front of the power supply. This LED is marked "Reverse Bat.". CR113 eliminates a path for the reverse battery current through the relay and over/under voltage protection circuitry. In an overvoltage or undervoltage situation, whether AC is present or not, the red LED (CR105) lights until the problem is rectified. This light is located on the right-hand side of the battery back-up module when looking at the front of the power supply and is marked BAT-BAD. NOTE: Exceeding -30V across the battery back-up terminals with the power supply on will destroy Q105. 6-31 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION 6.8.6 BBM FAN CONTROL 6.9 CARD RACK The voltage supply to the thermal measurement circuit is taken from the 26.5V DC line into the BBM. A precision temperature sensor U106 is mounted on the PC board near a screw into the BBM bracket which transfers heat to the sensor. The output of this sensor is 10 mV/°C with a ±1% accuracy. This voltage is amplified by U105 with resistors R153/R154 setting the gain. The card rack provides slots for up to eight logic cards; including Main Processor Card (MPC), Main Audio Card (MAC) and the Interface Alarm Card (IAC). The IAC has a notch in the card to accommodate a pin in Slot-8 so that no other card can be plugged into this slot. On the back of the card rack is the Backplane with plug-in connectors to the cards and cables to the RF modules, Power Supply and External Connector Board. The output of this gain stage (pin 1) is fed to another gain stage that performs as a comparator. The output (pin 7) will go high when the heatsink temperature reaches 45°C and will go low when the temperature goes below 35°C. This output is sent to the power supply through Q106 to turn the fan on and off. Refer to the component layout and schematic diagram in Section 10 for more information on the repeater backplane.

The main controller (U27) is a VLSI (Very Large Scale Integration) CMOS 16-bit single chip computer with an 8-bit external data bus. This processor has software compatibility with the V20 (8086/8088), faster memory access, superior interrupt processing ability, and enhanced control of internal peripherals. This ROMless processor has a variety of on-chip components including 256 bytes of RAM, serial and parallel inputs/outputs, comparator port lines and timers. Control functions for each repeater are performed by the Main Processor in the MPC installed in each repeater. The MPC contains the main software and control over the repeater via microprocessor U27 (see Figure 6-20). Information is exchanged between repeaters via a High-Speed Data Bus (HSDB) that interconnects all the MPCs. This control technique is called distributive processing and it eliminates the need for a separate system controller at each site. The HSDB processor (U13) on the MPC provides these control functions. The MPC also contains: • Flash Memory, RAM, non-volatile EEPROM. • I/O chip select to allow the addressing of data latches for Input/Output. • Read/Write selection to be sent and received on the Controller Backplane. • Clock line, data line and chip select line from the IAC to load the Receiver and Exciter synthesizers. • Serial communication circuitry and processes for the High Speed Data Bus (HSDB). • Asynchronous parallel communication to the other cards, i.e. alarm input and output circuitry. • AC Power Failure indication from the IAC. • Provides an output from the IAC to the power amplifier to control the output power. • Exciter Logic Push-To-Talk (PTT). October 1999 Part No. 001-2009-201 Receiver synthesizer lock, Exciter synthesizer lock, thermal level from the power amplifier, VSWR level from the PA, forward power level, RSSI signal level, audio levels from the MAC, Receiver and Exciter from the IAC. Eight banks of registers are mapped into internal RAM below an additional 256-byte special function register (SFR) area that is used to control on-chip peripherals. Internal RAM and the SFR area are together and can be relocated anywhere in the 1M-byte address space. This maintains compatibility with existing system memory maps. The two microprocessors and UART (U22) are reset by integrated circuit U17. Reset occurs when power is turned on, when the 5V supply drops below a threshold level or the reset switch (S1) is active. When a microprocessor is reset, several internal registers are cleared and the program is started over from the beginning. Low-voltage reset prevents improper operation resulting from low-voltage conditions. When power is turned on, the RESET output U17, pin 6 is initially high and the inverted RESET output U17, pin 5 is initially low. Once the 5V supply stabilizes, these outputs remain in these states for approximately 100 ms to ensure that reset occurs. This time delay is set by capacitor C14 connected to U17, pin 3. If the 5V supply drops below a nominal level, the RESET outputs change states and microprocessor operation is interrupted until the 5V supply returns to normal. C3 prevents fast transients on the 5V supply from causing reset. 6-34 CIRCUIT DESCRIPTION P2-0 STAGING STAGING LATCH LATCH ADM P2-1 PROGRAMMABLE LC DMA etc. A19-A0 P2-2 P2-3 CONTROLLER P2-4 ALU P2-5 PSW TxD0 RxD0 SERIAL P1-6 COMMUNICATION CTS0 INTERFACE PC PFP TxD1 RxD1 CTS1 INC BAUD RATE GENERATOR TA RESET TB INT ROM P2-6 16K BYTES P2-7 TC P1-1 PROGRAMMABLE P1-2 INTERRUPT P1-3 CONTROLLER BUS CONTROL LOGIC P1-0 INT RAM 256 BYTES GR MACRO SERVICE CHANNEL P1-4 P1-7 MSTB MREQ R/W IOSTB EA INSTRUCTION DECODER X1 CLOCK MICRO SEQUENCER X2 P1-4 MICRO ROM QUEUE D7-D0 16-BIT TIMER PORT WITH PORT TIME BASE CONTROLLER COMPARATOR P1-5 REFRQ P0-7 V P0 P1 P2 TH PT0-PT7 Figure 6-15 U27 BLOCK DIAGRAM Manual reset can be accomplished by pressing push-button switch S1. When U17, pin 2 goes low, U17 goes into the reset sequence described. Microprocessor U13 is an 8052 that uses external EPROM (Erasable Programmable Read Only Memory) U14, an 8-bit device that stores the program. The microprocessor uses 2k x 8 EPROM and 64k x 8 RAM. The RAM (Random Access Memory) is used for temporary data storage. The HSDB processor is configured by the Main Processor. 6.11.3 HIGH SPEED DATA BUS MICROPROCESSOR (U13) The HSDB processor (U13) on the MPC provides the interface with the HSDB. It monitors data on this bus and also transmits data on to this bus when necessary. Information on this bus indicates which repeaters are in use and also which mobiles are using the system. This information is used by the repeater to encode data messages to the mobiles that are monitoring that channel. These messages also include information on which repeater is free and current system priority. The internal data bus of the microprocessor has four input/output ports. These ports have eight lines each, giving a total of 32 input/output lines. These ports are designated P0, P1, P2, P3. P0 is used as a data bus. Ports P1 and P2 are always used as general purpose inputs/outputs. P3 is used for specialized functions, i.e. a serial port (RxD/TxD) and interrupt (INT). 6-35 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION The operating speed of the microprocessor is set by an 11.059 MHz clock generated by Y2. This clock frequency is divided down by an internal divider to provide a machine cycle time of 1.08 µs. Most program instructions are executed in one machine cycle and none require more than four machine cycles. Pin 15 MREQ The microprocessor U13 communicates with the main processor (U27) through U9 and U10. U9 is a Transmit FIFO (First In First Out) and U10 is a Receive FIFO. This combination makes up an asynchronous parallel-to-parallel interface to the Main Processor. Pin 16 Microprocessor U13 also calculates the current system priority for the channel. This priority is from the programming software responses and the current priority is sent to the main processor. U13 also reads repeater number and channel number information in memory. U13 also determines the current free repeater and includes that information in the data sent to the main processor. Pins 17-20 UNUSED Pin 21 LPTT A memory request line operates in conjunction with the Read/Write lines. These provide the ability to read from or write to the main processor memory on the MPC. MSTB A memory strobe line is used during MPC main processor Read/Write operations to external memory on the MPC and other cards plugged into the backplane. The Logic Push-To-Talk is an open collector from the Controller. It has a sink capability of 20 mA and a maximum voltage rating of 18V. The transmitter should produce power when this pin is a logic low. Transmit indicator is on the IAC and is controlled independently of the LPTT. 6.11.4 CHIP SELECT DECODERS (U15/U4) These select the peripheral chip to read from or write to. Pins 22-23 UNUSED 6.11.5 P1 SIGNAL CONNECTOR Pins 24/56 HSDB+/HSDB- This is the signal interface connector P1 (64 pin) that connects the Address and Data buses and control lines to the backplane connector. This interconnects all repeaters to provide an exchange of information. This control technique is called distributive processing and eliminates a separate system controller at each site. Information on this bus indicates which repeaters are in use and also which mobiles are using the system. This information is used by the repeater to encode data messages to mobiles that are monitoring that channel. These messages also include information on which repeater is free and current system priority. Pins 1-10 Pins 33-42 Address Bus This provides a path between the MPC main processor and the external memory on the MPC and the other cards in the Controller. This bus retrieves information programmed into memory for the operation of the repeater. Pins 11-14 Pins 43-46 This provides a means of transferring data to and from the CPU on the MPC, memory storage on each card and peripheral devices in and out of the MAC and IAC.

The normal setting is pin 1 to pin 2. 6.12.1 INTRODUCTION Pin 1 Pin 2 Pin 3 This control card stores the information required to operate the routing of audio and data from the inputs of the repeater to the outputs. Data is received on the address bus from the MPC for the operations to perform. The Audio/Data microprocessor and the latches open and close gates to route a path for the audio or data. +12V U25, pin 1 Vpp +5V 6-37 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION When it is time to transmit the CW Identification, the main processor on the MPC sends the identification to U111 via the data bus and U160 (Rx FIFO). The CWID is sent to the Tx Data Amplifier and Filter. The output of the filter is summed with the transmit audio and sent to the Exciter. Audio control functions for each repeater are performed by the main processor in the MPC. The MPC contains the software and maintains control over the repeater via microprocessor U27. The audio/data microprocessor passes received data to the main processor, and it is given the programmable parameters for the gates. U111 also uses six octal latches to provide additional input and output lines. Latch U107/U108 provide outputs which allow U111 to control various audio gates. These gates control the CWID, FSK data, and receive/transmit audio signals. Information is exchanged between the cards in the Controller Backplane via a data bus and an address bus. The address bus provides the link between the main processor and the chip and the address latches on the MAC. These latches control the octal latches that select the audio and data gates. The data bus is the link between the main processor and the audio/data processor on the MAC. The main processor controls the data to the octal latches and opens and closes the gates required to route audio/data in and out of the repeater. The MAC also contains: Latch U106 provides outputs which allow U111 to route signals to the Audio/Data Test Point by switching gates on and off. U106 also provides adjustment of the selected EEPOTs. U155-U156 allow U111 to select the EEPOT to adjust with chip select lines. These latches also provide routing of some audio/data signals through gates. 1. The audio interface between the receiver and exciter and to the external connections. In addition U111 controls the receive and transmit audio gates, receiver squelch, several front-panel indicators, and other functions. U111 encodes the data messages transmitted to mobiles monitoring that channel, and controls transmitter keying. 2. The receive audio filtering with de-emphasis. 3. The squelch filter and detector. 4. Slow decay timing circuit that controls a mute gate on the main receive audio. 6.12.3 RECEIVE AUDIO The Receive Wide Band Audio (RX WBAND) signal from the Receiver is fed into the MAC on P100, pin 27. This audio signal includes; audio, LTR data, and noise. The audio processing circuit provides filtering and amplification of the audio signal before it is routed to the outputs on the MAC card. 5. A filter, DC restoration and slicer circuitry for detecting the subaudible data. 6. The fast squelch and data fed to the microprocessor that decodes the data and uses the squelch line as a data qualification signal. A low-pass filter consisting of U121A/B attenuates frequencies above 3 kHz. This removes high-frequency noise from the audio signal. From the filter the signal is fed to amplifier U122A to increase the level before the high-pass filter to preserve adequate hum and noise ratio. 7. Transmit audio filter and limiter with pre-emphasis. 6.12.2 AUDIO/DATA MICROPROCESSOR (U111) From the audio amplifier the signal is fed to a high-pass filter consisting of U122B/C/D. This filter attenuates frequencies below 300 Hz which removes data present in the wide band audio signal. These filters are configured to act like large inductors. The signal is then fed to U163A which provides 6 dB per octave de-emphasis. This Audio/Data microprocessor is on the MAC card and is used to decode LTR data received from the mobiles. The LTR data is applied to U111, pin 8 (P1.7 input). When a word is successfully decoded the data is then sent to U161 (Tx FIFO) and transmitted on the data bus in parallel to the main processor on the MPC. October 1999 Part No. 001-2009-201 6-38 CIRCUIT DESCRIPTION 6.12.5 RECEIVE DATA CIRCUITRY Audio gates U113B/C/D permit noise squelch circuit, control logic, and audio switch to control gating of the audio signal. The control signal from the noise squelch circuit is applied to U113B through U113D. When a carrier is detected, this input is high and U113B passes the signal. Programming determines the gating of audio. When audio is passed by U113B/ C and U114A, the audio can be routed through other gates to various outputs (see Section 6.12.6). The receive wide band audio signal is the unfiltered output of discriminator U202 in the Receiver. Therefore, this signal contains audio, LTR data, and noise. A low-pass filter formed by U124A/B attenuates frequencies above 150 Hz by 24 dB per octave so that only the data frequencies are passed. From the filter the signal is fed to amplifier U125A. The gain of U125A is adjusted by a level control. The output of U125A can be routed through Data To Audio/Date Gate U159C and the Audio/Data Test Point J100. 6.12.4 RECEIVE SQUELCH CIRCUITRY DC restoration circuit converts the data signal from AC floating near ground to a digital signal at levels of 0 and 4.5V. U125B/C provide the reference voltage on the inverting input of comparator U125D. Positive peak detector U125B handles the positivegoing peaks of the data signal. Negative peak detector U125C handles the negative-going peaks of the data signal. The receive wide band audio includes audio, data and noise. The squelch circuit detects this noise to determine receive signal strength. When no carrier or a weak carrier is received, there is a large amount of noise present. Conversely, when a strong carrier is present, there is very little noise present. U135A is a high-pass filter which attenuates frequencies below approximately 30 kHz so that only high-frequency noise is passed. This noise is amplified by U135B and U123A. A level control adjusts the gain of amplifier U135B. The gain of U123A is partially set by a thermistor to compensate for circuit gain and noise level changes caused by temperature variations. The voltage on non-inverting input to U125D is midway between the positive- and negative-going peaks. The data input is on the non-inverting input of U125D. When the data signal rises above the reference voltage, the output goes high. Conversely, when the input voltage drops below the reference voltage, the output goes low. The receive data is then passed to audio/data processor U111. The amplified noise is then applied to a bridge rectifier. The difference between bridge rectifier outputs is applied to the inputs of U123B. The output of U123B is positive-going pulses. These pulses are applied to U123C which is a Schmitt trigger. When the input signal rises above the reference, the output goes low and causes the reference voltage to decrease slightly adding hysteresis to the triggering level. This hysteresis prevents intermittent squelching when the receive signal strength is near the threshold level. 6.12.6 RECEIVE AUDIO PROCESSING The receive audio signal is fed into the MAC on P100, pin 27. When a mobile-to-mobile call is received, Repeat Gate U153C is enabled and the receive audio signal is routed through Transmit Option Gate U158C to the input of the transmit audio buffer U164B to be retransmitted. Repeat Gate U153C is controlled by processor U111 through latch U107. A logic 1 on the control input causes the signal to be passed. The output of U123C is applied to U123D and Logic Squelch to Audio/Data Gate U159B and audio/ data processor U111. Gate U159B routes the squelch output to the Audio/Data Test Point J100. U123D functions as a timing buffer. The output of U123D is applied to Receive Squelch Active Gate U113D. When this gate is closed, the squelch circuit controls Normal Receive Gate U113B to block receive audio if no signal is present. When the received audio must be routed to the backplane (i.e. for other cards), Receive Voice Gate U115B is enabled by processor U111/latch U108 and passes the audio signal to amplifier U120B. Receive To Backplane (RX TO BP) U115C is enabled and passes the amplified audio to the backplane. 6-39 October 1999 Part No. 001-2009-201 CIRCUIT DESCRIPTION bridge. When a high-level signal is applied to the bridge, the bridge opens and the output of the bridge is limited to a specific level. When the audio received must be routed to the external speaker or speaker/microphone, Local Audio Mute Gate U114D is enabled by U111/latch U108. The audio is passed to local audio output amplifier U132. The gain of U132 is adjusted by the local audio volume control and the on/off switch. The output of the limiter passes to a composite 6pole splatter filter formed by U127A, U128D and U128A separated by buffers U128B and U128C. 6.12.7 COMPANDOR OPTION The output from U128A is fed to Normal Modulation Mute Gate U118B that is controlled by A/D processor U111/latch U106. When enabled, the gate passes transmit audio to EEPOT U149. U149 is an electronically adjustable potentiometer that adjusts the gain of transmit audio amplifier U129C. The gain of U129C can only be adjusted through the software, therefore, a computer must be attached to the MAC card when levels are set. The compandor option enhances the receive and transmit audio when used in conjunction with the Telephone Interface Card (TIC) in LTR systems. The filtered Receive Audio passes through the Receive Mute Gate U113C to the expander input on A301, pin 1. The expand output of A301, pin 2 is coupled to the audio outputs by U114C. The output of U129C is fed to summing amplifier U129B where it is combined with LTR transmit data and CWID when present. The gain of audio and data are the same so unity gain is produced. The output signal is fed to the TCXO where it frequency modulates the transmit signal. The TX-VOICE on P100, pin 32, passes through the TX Voice Gate U158A to the expander input on A301, pin 5. The compressed output of A301, pin 4 is passed to the Transmit Audio Buffer. 6.12.8 TRANSMIT AUDIO 6.12.9 TRANSMIT AUDIO PROCESSING PTT switch (Q101/Q102) provides local microphone Push-To-Talk (PTT) indication to U105. U105 then tells U111 via the data bus that the local microphone PTT has been activated. Transmit voice from the backplane comes into the MAC on P100, pin 32. When used this signal passes to the transmit voice amplifier U130A. The output level of the amplifier is adjusted by a level control. The output of U130A is applied to another transmit voice amplifier U130B and Transmit Voice Gate U158A. U158A is controlled by A/D processor U111/ latch U107. When enabled, the gate passes the voice to Transmit Option Gate U158C and on to the transmit audio buffer U164B. Transmit Voice amplifier U130B is adjusted by a level control. The output is fed to Transmit Net Gate U153B. Gate U153B is controlled by A/D processor U111/latch U155. U164A amplifies the microphone audio signal to provide the correct input level to U164B. Local Microphone Mute Gate U117C is controlled by A/D processor U111/latch 106. The function of U117C is to mute the local microphone audio when the local microphone PTT switch is pressed. This prevents interference if the microphone remains live when the PTT switch is pressed. Buffer U164B combines the microphone audio signal from U164A with the audio signal from the Repeat Gate U153C. 6.12.10 TRANSMIT DATA AND CWID PROCESSING U127B/C form a high-pass filter that attenuates frequencies below 300 Hz to prevent interference with the LTR data applied at U129B. Pre-emphasis at 6 dB per octave is provided by an RC combination before the signal is fed to the Limiter U127D. The data signal is produced by A/D processor U111 on Transmit Data and Transmit Shape outputs. The transmit shape output is normally the opposite logic level of the transmit data output when data is transmitted. However, the bit before a logic transition occurs, the transmit shape output is the same logic level as the transmit data output. This results in a Limiter U127D and rectifiers form a precision limiter which prevents over modulation caused by high-level input signals. With normal input levels, the output of a bridge rectifier follows the input of the October 1999 Part No. 001-2009-201 6-40 CIRCUIT DESCRIPTION filter passes the 800 Hz fundamental present in the signal. The output of the filter is jumpered by P106 on J106, pins 2/3 and P107 on J106, pins 4/5 to the summing amplifier and applied to gate U118D, and to the modulation input of the Exciter. logic 1 level that is slightly higher and a logic 0 that is slightly lower. This pulse shaping minimizes interference between data bits when the data is filtered by the low-pass filter. The data from U111 is fed to buffer U126A and Transmit Data Enable Gate U117B. Gate U117B is controlled by A/D processor U111 directly. When enabled this gate passes the data to EEPOT U151. U151 is an electronically adjustable potentiometer that adjusts the gain of transmit audio amplifier U126B. The gain of U126B can only be adjusted through the software. Therefore, a computer must be attached to the MAC card. U126B provides the required signal level at the output of the low-pass filter. A relatively stable DC bias voltage for U126C/D is required because these stages are DC coupled to the transmit TCXO (see Section 6.2.2) and changes in bias voltage can cause fluctuations in the transmit frequency. The input and output connectors for the MAC are defined as follows. 6.12.11 P101 SIGNALING CONNECTOR The signal interface connector P101 (64 pin) connects the Address and Data buses and control lines to the backplane connector. See Figures 6-21 and 6-22. Pins 1-10 Pins 33-42 ADDRESS BUS This provides a path between the MPC main processor and the processor and memory of the MAC. This bus retrieves information programmed into memory for the operation of the MAC. U126C/D form a low-pass filter that attenuates square-wave harmonics in the data signal above 150 Hz to prevent interference with the audio band. From this filter the signal is fed to summing amplifier U129B and combined with the transmit audio signal. The output of U129B is fed to Transmit Modulation Mute Gate U118D. This gate is controlled by A/D processor U111/latch U106. When enabled, transmit audio and data is passed to the Exciter modulation input and the transmit TCXO. Pins 11-14 Pins 43-46 DATA BUS This data bus provides a means of transferring data to and from the processor on the MAC with peripheral devices in the MAC. When needed, the External Modulation input on P100, pin 11 is fed to External Modulation Mute Gate U118C. Gate U118C is controlled by A/D processor U111/latch U106. When enabled, this gate passes the modulation on pin 11 to the summing amplifier U129B and gate U118D to the modulation input of the Exciter. Pin 15 MREQ A memory request line operates in conjunction with the Read/Write lines. These provide the ability to read from or write to the processor memory. Pin 16 The repeater on the lowest frequency channel in each system must periodically transmit the station call letters as a continuous-wave identification encoded by Morse Code. This identification is programmed with the Edit Parameters software. MSTB This is a memory strobe line used during MAC processor Read/Write operations to external memory. The CWID output is controlled by A/D processor U111/latch U107. This output is fed to CWID tone generator U100B/A and turns the tone generator on and off to create the Morse Code. From the tone generator the signal is fed to bandpass filter U129A. This Pins 17-20 UNUSED Pin 21 LPTT The Logic Push-To-Talk is not used on the MAC.

Data to the relay is latched by a write to the base address. 6.12.15 J102 LOCAL MICROPHONE The IAC activates relays when alarm trigger events occur. The IAC monitors for alarm activity in the system and can set the various output relays as defined by the user during programming. When an external alarm is set it can be monitored from a remote location. Refer to Section 4.3.3 for alarm programming.

Then the RF Shutdown alarm (#32) is mapped for alarm 1 in each repeater. This configuration allows Repeater 2 to give an alarm when Repeater 1 has an RF Shutdown alarm output, etc. ALARM 1 IN +/ALARM 1 IN - This is an input received from a connection to an external device as a specific alert condition.

The receiver and transmitter frequencies are locked to the 1.250000 MHz reference frequency from the local oscillator drawer. This frequency is stable to within ±0.1 PPM from -30°C to +60°C as required by the FCC. To properly align the IF sections of the receiver, the signal generator must have similar stability. Since most test equipment is not this stable, a separate reference oscillator that is stable to ±0.05 or ±0.01 PPM may be needed to clock the signal generator and frequency counter. Measure the voltages at the following pins. U206, pin 1 U207, pin 1 U208, pin 1 U210, pin 1 +12V DC ±0.4V +12V DC ±0.4V +6V DC ±0.2V +12V DC ±0.4V 7.2.3 PROGRAM TUNE-UP CHANNEL Adjustment of the 1.250000 MHz reference frequency probably should not be attempted for the same reason. Unless the communications monitor has a stability of ±0.01 PPM or better, the repeater frequency may be more correct than that of the monitor. If it is certain that one or both oscillators in the local oscillator drawer are off frequency, there is an adjusting screw on the oscillators that is used to change the frequency slightly. Adjustment should only be performed when the ambient temperature is near the calibration reference of 25°C (77°F). 1. Using the PC and software, program the Synthesizer for the Receive channel number. 2. Tune the VCO helical L220 for +4.5V DC ±0.05V on U209, pin 6 or TP2. 3. Alternately tune L223 and L224 in 1/2-turn to 1-turn increments until a voltage is measured on J201, pin 13 or TP5. At that time, tune L223 for a peak, then L224 for a peak. 4. Retune L223 and L224 for a peak at J201, pin 13. If power is removed from the local oscillator drawer, the oscillators require a minimum restabilization period of 30 minutes. No fre- quency-critical adjustments should be attempted until the oscillator frequency has stabilized. NOTE: The Channel Number, Channel Frequency and Synthesizer Frequency appear at the bottom of the screen. 7.2 RECEIVER ALIGNMENT 7.2.4 TCXO FREQUENCY ADJUST Refer to Figure 7-1 for component locations. Refer to Figure 7-9 for equipment needed and setup diagram. 1. Set Y201 (TCXO) for 3.5V DC ±0.05V DC at TP1 (response time is very slow). 7.2.1 PRE-TEST 7.2.5 VCO TEST 1. Preset L201, L202, L203, L204, L206, L223 and L224 tuning screws about 1/4 inch above the top of the casting. 2. The Synthesizer is programmed for 199 channels above the Receive Channel. 3. The voltage on U209, pin 6 (TP2) should be < 7.5V DC. 2. Preset L202 and L205 tuning screws so they are just barely above their tightening lock nuts. 4. Record the voltage on J201, pin 13 (TP5) ____. 7-1 October 1999 Part No. 001-2009-201 ALIGNMENT AND TEST PROCEDURES 8. Tune C207, L209, L211 and L225 for peak voltage on J201, pin 7 (TP3). Decrease the generator output level to maintain 2-3V. Distortion should be <5% (typically < 3%). 5. The Synthesizer is programmed for 199 channels below the Receive Channel. 6. The voltage on U209, pin 6 (TP2) should be > 2V DC. 9. Repeat Steps 4, 5 and 6. 7. Record the voltage on J201, pin 13 (TP5) ____. 7.2.7 AUDIO DISTORTION 8. If the voltages recorded in Steps 3 and 6 are not within ±0.2V, tune L224 as required to balance the voltage readings. 1. Plug a 16 ohm resistive load at J101 or J104 on the MAC (Main Audio Card). 2. Connect a distortion analyzer to the 16 ohm load. 9. The Synthesizer is reprogrammed for the Receive Channel. 3. Measure the distortion of the receive audio at J101 or J104 on the MAC with the local volume control set to 2.8V RMS. 7.2.6 FRONT END ADJUSTMENTS 4. The reading should be less than 3% (typically < 1%). 1. Set the signal generator to the Receive Channel at a level sufficient to produce an output voltage on J201, pin 7 (TP3) (RSSI Output). 5. Measure receive sensitivity at J101 or J104 on the MAC. 2. Tune L204, L205, L206, L201, L202, L203 and L204 for a peak voltage on J201, pin 7 (TP3). Decrease the generator output level to maintain a 23V reading at J201, pin 7. 6. The reading should be < 0.35 µV (typically < 0.25 µV). Optional: Adjust L207, L209, L211, and L225 for best distortion and recheck sensitivity. 3. Set the generator to 1000 µV with a 1 kHz tone at ±1.5 kHz deviation (100 µV at the Rx antenna with 20 dB pad on the generator). 7. The Synthesizer is programmed for 199 channels above the Receive Channel. 8. The receive sensitivity should be < 0.35 µV (typically < 0.3 µV). Optional: Adjust L204 to balance sensitivity at ±199 channels if needed. 4. Tune the Quadrature detector coil Z213 for maximum AC voltage on J201, pin 9 (TP4). 5. Adjust R264 for 387 mV RMS, ±5 mV RMS, on J201, pin 9. 6. Adjust R284 for 2V DC ±0.05V DC on J201, pin 9 (TP4). 9. The Synthesizer is programmed for 199 channels below the Receive Channel.

Connect the: power supply ground lead to P105, +15V DC lead to P103, +26.5V DC lead to P101 and the 36-pin cable to J101 on the RFIB. Refer to Figures 7-3 and 7-5 for component locations. Refer to Figure 7-11 for equipment needed and setup diagram. Select "PA" from the "TEST" menu in the Repeater Programming Software. 2. Connect attenuator and power meter to A8. 3. Set R663 fully counterclockwise. IMPORTANT NOTE 4. Set R76 on the RFIB fully counterclockwise. No field alignment is required. Adjustments in Sections 7.4.2 and 7.4.4 are part of a new unit production test procedure. They should only be performed as required on "out-of-warranty" and "field-repaired" units. Broken seals on R76, R663 or R680 will void the warranty! Full power control range of 25-75W is controlled by the repeater configuration parameters under the Edit-Setup Parameters menu selection. 5. Set the signal generator to +16 dBm ±0.1 dB at 937.5 MHz. NOTE: All cable and attenuator losses must be measured and incorporated into this measurement. The adjustments in Section 7.4.2 provide for proper matching for the output of Q501 and set a protective limit on the drive to the final transistors. This limit is approached only under certain unusual operating or repair conditions. However, improper adjustment may impair normal operation of the PA, especially at temperature extremes. CRITICAL ADJUSTMENTS 6. Press the space bar to key the PA. 7. Adjust R663 for 85W ±2W (±0.1 dB). 8. Verify that Output 1 is within 20% of Output 2. If Q501 or U501 are replaced, only Section 7.4.2 adjustments should be performed. No other adjustments are necessary in this case. Replacement of RF components surrounding Q501 and U501 does not justify performance of Section 7.4.2 adjustments. Replacement of active components within the power control circuitry of the RF Interface Board would require Section 7.4.2 adjustments. 9. Press the space bar to unkey the PA. 7.4.3 PRE-DRIVER POWER LIMIT ADJUSTMENT 1. Set a power reference of 0 dB at 85W. Section 7.4.2 adjustments are necessary only if repairs are made and such repairs are likely to affect the sensitivity/calibration of the forward or reverse power detectors (e.g. replacement of detector diodes CR651/CR652 or of the entire forward/reverse power detector assembly). Replacement of components within the power control circuitry of the RF Interface Board are unlikely to affect the calibration of the power control. 2. Monitor the Transmit current and RF output level. Use the Up Arrow key to increase the power level until 0.6 dB above 85W (97W) is reached or peak PA output. NOTE: If the Transmit current begins to increase rapidly and is not constant with time, then unkey the PA immediately and troubleshoot. NOTE: Replacement of Q501, Q502, Q503 or U501 does not require the adjustments in Section 7.4.2. 7-5 October 1999 Part No. 001-2009-201 ALIGNMENT AND TEST PROCEDURES 3. Adjust power limit control R76 clockwise until power is limited to 0.55 dB above 85W (95W). If the maximum PA power is < 95W, adjust R76 until power begins to decrease. 7.4.4 REFLECTED POWER ADJUST 1. Remove the load cable from A8. 2. Press the space bar to key the PA. NOTE: This will not harm the PA. 3. Adjust Reverse Power Calibration Pot R680 for equal voltages on W126 and W121 on the RFIB or for equal Forward and Reverse Power. 4. Press the space bar to unkey the PA. 5. Apply "Glyptol" to R663, R680 and R76. 6. Press F4 to turn on/off fans. Both PA fans should turn ON. 7. Measure temperature detector voltage at W127 on the RFIB. Normal output at 25°C ambient is approximately +1.0V DC.

Important checks are receiver sensitivity and transmitter frequency, modulation, and power output. It is recommended that repeater performance be checked regularly even though periodic checks are not specifically required by the FCC. Synthesizer malfunctions can be caused by no VCO output, or the VCO is unlocked. The VCO can be unlocked due to a bad synthesizer chip, an incomplete synthesizer phase-lock loop, or because the synthesizer chip is programmed incorrectly. To make certain that the synthesizer chip is receiving programming data, pins 17, 18 and 19 of the chip should be monitored during programming. Pin 17 (Enable) will go from a high to a low level. Pin 18 (Clock) will go from low to high in narrow pulses. Pin 19 (Data) goes from high to low with wider data pulses. 8.1.2 SURFACE-MOUNTED COMPONENTS A large number of the components used in this repeater are the surface-mounted type. Since these components are relatively small in size and are soldered directly to the PC board, care must be used when they are replaced to prevent damage to the component or PC board. Surface-mounted components should not be reused since they may be damaged by the unsoldering process. For more information on replacing surface-mounted components, refer to the Surface-Mounted Device Handbook, Part No. 0010576-002. When the VCO is locked, the lock detect line of the synthesizer pin 2 is high with very narrow negative-going pulses. These pulses become wider when the VCO is out of lock. When this unlock condition exists either in the Exciter VCO or the Receiver VCO it is relayed by the RF Interface board and is detected by the MPC via the RF Data lines. The MPC then does not allow the transmitter to key and the receiver cannot unsquelch. 8.1.3 SCHEMATIC DIAGRAMS AND COMPONENT LAYOUTS When the VCO is unlocked, the fR and fV inputs to the phase detector are not in phase (refer to Sections 6.1.15 and 6.2.8). The phase detector in the synthesizer then causes the VCO control voltage to go to the high or low end of its operating range (0 or 9V). This in turn causes the VCO to oscillate at the high or low end of its frequency range. Schematic diagrams and component layouts of the PC boards used in this repeater are located in Section 10. A component locator guide is also provided for both the schematic and board layouts to aid in component location. 8.1.4 REPLACEMENT PARTS LIST As shown in Figures 6-1 and 6-4, a loop is formed by the VCO, buffer, frequency input (FIN) and the phase detector output (PD OUT). Therefore, if any of these components begin to malfunction, improper signals appear throughout the loop. However, correct operation of the counters can still be verified by measuring the input and output frequencies to check the divide number. A replacement parts list containing all the parts used in this repeater is located in Section 9. Parts are listed alpha numerically according to designator. For information on ordering parts, refer to Section 1.9. 8.1.5 TCXO MODULES NOT SERVICEABLE Transmit or Receive TCXOs are not field serviceable because if a part is changed, a factory recalibration must be performed to ensure that it stays within its ±1 PPM tolerance. Proceed as follows to check the input and output signal of the synthesizer modules to determine if they are operating properly. 8-1 October 1999 Part No. 001-2009-201 SERVICING 8.2.2 TCXO MODULE Modulus Control Signal Check the signal at TCXO, pin 5. It should be 17.5 MHz for Y201 and Y401 at a level of approximately 3V P-P. If the TCXO is defective, it is not serviceable and must be replaced with a new unit as described in Section 8.1.5. 1. The frequency of the modulus control signal on TEST 1, pin 9 should be equal to the N counter output frequency (either in or out of lock). When the VCO is in lock, this frequency should be 12.5 kHz. 2. The duty cycle of the modulus control signal determines the divide number of the prescaler. The duty cycle (T1 ÷ T2) should be as follows: Measure the signal at pin 20 (Ref In) of the synthesizer chip. It will be approximately 1V P-P. If the signal is low here, the TCXO buffer circuit may be defective. T1 ÷ T2 = A Cntr Div No ÷ N Cntr Div No T2 = 80 µs when locked. 8.2.3 VOLTAGE CONTROLLED OSCILLATOR (VCO) Check for VCO output signal with a high impedance RF voltmeter. If there is no output signal, or if the frequency is greatly off, the VCO is defective. 0V Next, monitor the signal level at pin 11 (F In) of the synthesizer chip. If the signal is less than 100 mV P-P, the VCO buffer is defective. T1 T2 10us/DIV 2V/DIV Lock Detector Figure 8-2 MODULUS CONTROL WAVEFORM When the VCO is locked on frequency, the waveform at pin 2 (Lock Det) should be as follows. When the VCO is unlocked, the negative-going pulses should be much wider than those shown in Figure 8-1. If the lock detect circuit is operating properly, check prescaler input pin 11 (F In). If the modulus control signal is not correct, the synthesizer may be defective or the logic may not be programming the correct divide number. 8.2.4 INTERNAL PRESCALER The operation of the N and A counters can be observed by monitoring pins 16 and 19. Pin 16 (fV) equals fin ÷ (64N+A) = 12.5 kHz if the synthesizer is locked. Pin 9 is the modulus control signal. Checking Prescaler Divide Number The prescaler divide number can be checked by measuring the input and output frequencies. The prescaler divide number can be calculated as follows. (A and N counter divide numbers are calculated as described in Section 8.2.5.) Prescaler Divide Number = 64 + (A Cntr Div No ÷ N Cntr Div No) 0V 50ns 80us 10us/DIV 2V/DIV Example: Channel 200 (receive) Prescaler Div No = 64 + (60 ÷ 1056) = 64.0568 Figure 8-1 LOCK DETECT WAVEFORM October 1999 Part No. 001-2009-201 8-2 SERVICING "A" Counter Measure the prescaler input frequency at fin, pin 11. Then measure the output frequency at TEST 2, pin 13 and calculate the divide number. If the VCO is not locked on frequency, the divide number should still be correct. The measured frequencies may not be exactly as calculated due to counter accuracy and resolution limitations. A Counter Divide Number = (VCO freq (MHz) ÷ .0125) - (N Cntr Div No x 64) Example: Channel 200 (receive) NOTE: The counter should be connected to a high stability reference oscillator. A Cntr Div No = (845.550 ÷ .0125) - (1056 x 64) = 67,644 - 67,584 = 60 Example: Channel 300, VCO locked on frequency Example: Channel 200 (transmit) 845.550 MHz (pin 11) ÷ 13.200 (pin 13) = 64.0568 A Cntr Div No = (937.500 ÷ .0125) - (1171 x 64) = 75,000 - 74,944 = 56 8.2.5 CALCULATING "N " AND "A " COUNTER DIVIDE NUMBERS 8.3 RECEIVER SERVICING "N" Counter To isolate a receiver problem to a defective section, start by checking the DC voltages shown in Section 6.6.6 and on the schematic diagram (Section 10). If that does not indicate the problem, perform the performance tests in Section 7.2 to isolate the problem. If the synthesizer is out of lock, the receiver is also nonfunctional because the first injection and IF signals will be incorrect. N Counter Divide Number = Integer (VCO Freq. (MHz) ÷ 0.8) Example: Channel 200 (receive) VCO freq = 898.500 - 52.95 = 845.550 MHz N Cntr Div No = 845.550 ÷ 0.8 = 1056.9375 8.4 TRANSMITTER SERVICING Integer (whole no.) of 1056.9375 = 1056 To isolate a transmitter problem to a defective section, start by checking the DC voltages shown in Sections 6.6.4 and 6.6.6 and on the schematic diagram (Section 10). If that does not indicate the problem, perform the Performance Tests in Section 7.3, 7.4 and 7.5 to isolate the problem. If the synthesizer is out of lock, the Exciter is also nonfunctional because the software will not allow the repeater to transmit. Example: Channel 200 (transmit) N Cntr Div No = 937.500 ÷ 0.8 = 1171.8750 Integer (whole no.) of 1171.8750 = 1171 8.5 POWER SUPPLY SERVICING The power supply is a switch mode type with very high voltages. It is highly recommended that the power supply be returned to the factory for servicing (see Section 1.8). A parts list, schematic and component layout are provided for those customers that desire to do their own repairs (see Sections 9 and 10). 8-3 October 1999 Part No. 001-2009-201 SERVICING AC FAIL GND +5V +15V -5V +28V A 2 1 4 7 3 11 5 8 6 12 9 10 B C GND GND +15V THERMAL SENSE ON/OFF Figure 8-3 POWER SUPPLY REAR VIEW B- B+ TEMP REVERSE BATTERY CHARGER ON EARTH GROUND LINE BATTERY FAULT NEUTRAL Figure 8-4 POWER SUPPLY FRONT VIEW October 1999 Part No. 001-2009-201 CHARGER ACTIVE SWITCH 8-4 SERVICING The Japanese EIA Standard may also utilize a bar to indicate the temperature coefficient. Standby Battery Jack This provides a connection point for a +24V DC standby battery. Current is drawn from the battery only when the repeater enable line is on and AC has failed, or no AC is connected. A trickle charger can be jumpered in to charge the battery when AC returns. The charger jumper is removed when a separate battery charger is used (see Figure 8-4). The standby battery connection to the power supply must be ordered installed from the factory. Example: A2 - 100 pF NPO XX = NPO XX = N150 XX = N220 XX = N330 XX = N470 XX = N750 |XX = X7R 8.6.2 TANTALUM CHIP CAPS (510-26XX-XXX) NOTE: A small amount (<30 mA) of current is drawn from the batteries with the repeater off. If the repeater is going to be turned off for more than one week (with good batteries connected) the fuse should be removed from the DC cable harness. Tantalum chip capacitor identification varies with vendor and physical size. The positive (+) end is usually indicated by a colored board or beveled edge. The value and voltage may be indicated by printing on the capacitor or by using a special code. 8.5.1 VOLTAGE CHECKS 8.6.3 CHIP INDUCTORS (542-9000-XXX) Secondary voltages can be checked at the power supply connector with the power supply removed from the Repeater. First the on/off line must be grounded, jumper pin 5 to ground, then check the supply voltages as shown (see Figure 8-2). If voltages are absent the supply must be sent to the E.F. Johnson Company. Three colored dots are used to indicate the value of chip inductors. The two dots on the left side indicate the first and second digits of the value in nanoHenries, and the single dot on the right side indicates the multiplier (see Table 8-1). Example: Dots - Brown-Black-Red 8.6 CHIP COMPONENT IDENTIFICATION 10 nH x 100 = 1000 nH (1.0 µH) 8.6.1 CERAMIC CHIP CAPS (510-36XX-XXX) The last three digits of the part number are also the value and multiplier. The multiplier digits are shown in Table 8-1. Ceramic chip capacitors are identified using either an American or Japanese EIA standard. The values for both standards are shown in Table 8-2. 8.6.4 CHIP RESISTORS American EIA Standard The value of chip resistors is indicated by a number printed on the resistor. A 3-digit number is used to identify ±5% and ±10% resistors, and a 4-digit number is used to identify ±1% resistors. This uses a single letter or number to indicate the value, and the color of this letter or number to indicate the multiplier. The 3-digit number used to identify ±5% and ±10% resistors corresponds to the last 3-digits of the E.F. Johnson part number. This number is derived as shown. Example: Japanese EIA Standard This uses a letter to indicate the value followed by a number to indicate the multiplier. Example: 15 pF capacitor 273 339 American - Single Black "E" Japanese -"E1" 8-5 27k ohm 3.3 ohm October 1999 Part No. 001-2009-201 SERVICING Some resistors with a ±1% tolerance are identified by a 4-digit number and others may not have a marking. When identified with a 4-digit number, the first three digits are the value and the fourth is the multiplier.
