INTRODUCTION AND OPERATION
SECTION 1 INTRODUCTION AND OPERATION
1.1 SCOPE OF MANUAL
This repeater is modular in design for ease of service. 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:

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

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.

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

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.

INSTALLATION
SECTION 2 INSTALLATION
2.1 INTRODUCTION
NOTE: If the Repeater is installed in an area that
exceeds these environmental conditions, the site
should be equipped with air filters to remove dust and
dirt that could cause the equipment to overheat.
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.

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.

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).

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.

Temperature
The operating temperature range is -30°C to
+60°C (-22°F to +140°F), i.e. the same as the repeater.
The fan is thermostatically controlled by the internal
temperature. When the internal heatsink temperature
reaches +45°C (113°F) the fan turns on. When the
heatsink temperature drops below +35°C (95°F) the
fan turns off. If the internal heatsink temperature
reaches +90°C (+194°F) the power supply turns off
until the heatsink temperature drops below +85°C
(+185°F). The over-temperature shutdown and restart
are automatic.

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.

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.

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

•
Do not run ground wires parallel to any other wiring
(e.g. a ground wire parallel to a telephone line),
except other ground wires.
•

NOTE: Do not discard the packing materials. If you
must return an item, use the same packing materials
and methods (including static protective bags for circuit cards) to repack the equipment. You are responsible for proper repacking. E.F. Johnson cannot be
responsible for damage to equipment caused by negligence.
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.
NOTE: Each repeater should be grounded separately
by connecting a ground bus from the ground lug on the
back side of the RF module to the ground bar on the
rack (see Figure 2-7).

The repeaters are interconnected by a balanced
line High-Speed Data Bus (HSDB) consisting of a six
conductor cable. An RJ-11 to BNC Adapter Module
(see Table 1-1 and Figure 2-8) is used to connect existing (8X00) repeaters with VIKING VX repeaters and
is installed on the back of the VIKING VX cabinet
(see Figures 2-11, 2-12 and 2-13). The RJ-11 to BNC
Adapter Module is not necessary for systems that only
contain 200X repeaters of the same frequency band
(see Figure 2-10).

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).

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.

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

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).

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.

CIRCUIT DESCRIPTION
SECTION 6 CIRCUIT DESCRIPTION
6.1 RECEIVER
filtering of the receive signal is provided by 3-pole
helical filter L204-L206. 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. Additional

As shown in Figure 6-2, U202 contains second
oscillator, second mixer, limiter, detector and RSSI
circuitry. 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.

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. C222 and C238 match the output of the

CIRCUIT DESCRIPTION
The phase detector input signals are generated by
counters in U205 that are programmed to divide by a
certain number. 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.

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.

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,

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

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.

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

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.

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.

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:

CIRCUIT DESCRIPTION

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.

Figure 6-5 OCXO DRAWER BLOCK DIAGRAM
The OCXO drawer may be powered by the internal regulated 15V DC supply, or by an external 15V
DC source. 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).

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). Selection

Figure 6-7 OCXO SWITCHING
The top section of Figure 6-7 determines whether or
not a switch is made to OCXO 2. 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.

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.

Forward and reverse power is electromagnetically
coupled from the input and reflected ports of the circulator. 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.

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. During
normal operation, a signal of relatively equal phase
and amplitude is present on both ends of the balancing

CIRCUIT DESCRIPTION
6.7 800W POWER SUPPLY
C111. 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/

+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

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.

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.

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.

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.

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.

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.

6.11 MAIN PROCESSOR CARD
6.11.1 INTRODUCTION
The Main Processor Card (MPC) connects to the
computer with repeater software to program the
repeater parameters, sets and reads the alarms, handles communication between repeaters, maintains the
audio gating for the MAC, handles initialization
requests from cards and contains the repeater RF data
for the Receiver, Exciter and CWID.
6.11.2 MAIN CONTROLLER MICROPROCESSOR (U27)
This contains the main software and control over
the repeater (see Figure 6-15).
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).

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.

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).

CIRCUIT DESCRIPTION
The operating speed of the microprocessor is set
by an 11.059 MHz clock generated by Y2. This clock

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.

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.

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.

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

filter passes the 800 Hz fundamental present in the
signal. The output of the filter is jumpered by P106

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

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

audio and data is passed to the Exciter modulation

U129B and gate U118D to the modulation input of the

CIRCUIT DESCRIPTION
Pins 1-4
Pins 33-36
The third form is the output relay and to transmit
a 15-character description of the alarm over-the-air to
a remote location. The description is sent in Morse
code with a transmit ID assigned during programming.
A transceiver programmed with this ID can monitor
the repeater and alert the system owner when an alarm
occurs.
ADDRESS BUS (A12-A19 Only)
This address bus provides a path between the
MPC main processor and the latches and multiplexers
of the IAC. This bus retrieves information programmed into the MPC memory for the operation of
the IAC.
6.13.4 ALARM FUNCTIONS
Pins 5/37
The alarms can be configured in various modes to
alert the system owner to conditions and hazards with
the equipment and the repeater site facility. A few of
the possibilities are shown in Figure 6-19. In this
example the input alarm 2 of Repeater 1 is connected
to the door of the building, input alarm 3 of Repeater 5
is connected to the fire alarm system, the AC fail
alarm (#16 see Table 1-2) is mapped to alarm 2 output
so it can be transmitted (see Figure 4-10) and the output alarm 1 of Repeater 1 is connected to the input
alarm 1 of Repeater 2 and so on until the output alarm
1 is fed back to the input alarm 1 of Repeater 1. 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.
Pins 6/38
ALARM 2 IN +/ALARM 2 IN -

external device as a specific condition.
Pins 8/40
ALARM 4 IN +/ALARM 4 IN -
This is an input received from a connection to an
external device as a specific alert condition.
The input alarms are given a 15-character
description during programming and a Transmit ID.
These are used when an input alarm is activated to
send a Morse code message consisting of the description over the air to a monitoring transceiver programmed with this ID.
Pin 9
SQUELCH ENABLE
This is an output to rear connector J1. It can be
configured for inverted output, non-inverted output or
logic controlled non-inverted output.
There are 40 internal alarms that can be included
in the output alarm configuration (see Table 1-2).
These alarms can also be programmed to send an output as shown in the cross reference screen of the alarm
configuration menu (see Figure 4-10). Among these
alarms are the thermal sense from the PA and the AC
fail alarm output on the terminal block at the rear of
the repeater to activate the battery backup.
Pin 10
EXTERNAL REQ 2
This is an input received from a connection to an
external device.
Pins 11-14

ALIGNMENT AND TEST PROCEDURES
SECTION 7 ALIGNMENT AND TEST PROCEDURES
7.2.2 VOLTAGE MEASUREMENTS
7.1 OCXO AND TEST EQUIPMENT FREQUENCY STABILITY
Apply power to the Receiver by plugging the 20pin cable from the RF Interface Board into J201 (see
Figure 7-1).
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) ____.

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).

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.

ALIGNMENT AND TEST PROCEDURES
7.4.2 FORWARD POWER OUTPUT CALIBRATION
7.4 75W POWER AMPLIFIER ALIGNMENT
7.4.1 INTRODUCTION
1. 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.

SERVICING
SECTION 8 SERVICING
8.1 INTRODUCTION
8.2 SYNTHESIZER SERVICING
8.1.1 PERIODIC CHECKS
8.2.1 INTRODUCTION
This repeater should be put on a regular maintenance schedule and an accurate performance record
maintained. 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.

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

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

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).

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).

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:
