Circuit Configuration LPF The receiver is a single receiver with built-in DSP fully integrated. Incoming signals from the antenna, after passing through LPF filter, are fed direct to the DSP down converter to get the baseband voice from 0Hz to 3500Hz. Demodulated signals are filtered and conditioned onto a second DSP based filter, which also includes a high efficiency 4FSK modem. For digital demodulation, the recovered data is fed into a vocoder, which converts the data to voice. Analog voice from the analog path or the analog voice recovered from the vocoder, are fed into an audio power amplifier. Transmit signal frequency is generated by integrated VCO and PLL. RF frequency generated by the integrated RF chip is amplified into a 3-step amplifier then filtered by a low pass filter to be applied to the antenna. 4.2. Receiver System 4.2.1. Front-end RF Receiver Incoming RF signals from the antenna are delivered to the Receiver Unit and pass through a Low-pass filter, antenna switching ST-2112D SM R 1.2 SWITCH RECEIVER [U1] PROTECTION FILTER diode, and then fed to the receiver (U1) passing through a limiter BPF. 4.2.2. ANALOG Audio Processing RECEIVER [U1] AUDIO PROCESSOR [U5] AMPLIFIER [U10] The RF signal is tuned by U1, which includes a base band DSP audio processing, recovering flat audio from DC up to 3500 hz. The detected audio is amplified, filtered and conditioned inside of U5 which also includes a deemphasize filtering shape for received audio signals The output of the filtered and conditioned audio is delivered to an audio power amplifier (U10) then to the speaker passing through the external audio connector switch. 4.2.3. Virtual Squelch Circuit S/N ratio is measured by the receiver (U1) as the result of the analysis of the signal and the noise of the carrier. The output is sent to the main processor as a digital frame, which is analyzed by radio firmware, removing noise then qualifying the signal level. If the signal level is higher than the SMARTRUNK SYSTEMS, INC. 9 expected for the current programmed squelch threshold, then the processor analyzes the expected signaling programmed on the current channel table. In case of not any signaling is required, or the signal has been detected, the processor ask to the audio processor (U5) to open the audio path, unmuting the audio amplifier (U10). audio processor (U5) to open the audio patch. 4.2.6. ANALOG AUDIBLE SIGNALING DTMF signals, MDC1200 and tone signals are processed and decoded by the audio processor (U5). Decoded information or received tone is reported to the main processor (U8). 4.2.4. Virtual VOLUME CONTROL The potentiometer position (RV1) is measured by one analog to digital converter on the audio processor (U5), and then the information is reported to the main processor. The firmware immediately adjusts the audio processor path gain to get the appropriate overall circuitry volume control. Minimum volume, emergency and private audio level are controlled only by software overriding the information received from the DAC on U5. 4.2.5. Sub audio signaling Received sub audio signaling like CTCSS and DCS are received and processed by the receiver (U1) then detected on the audio processor (U5). Once decoded, the sub audio signaling is reported to the processor where the firmware compares it with the value programmed into the current channel programming. If the received signaling matches the channel programming, then the main processor (U8) requests the ST-2112D SM R 1.2 4.2.7. DIGITAL AUDIO PROCESSING Digital received information is processed by the receiver DSP (U1) RECEIVER [U1] AUDIO PROCESSOR [U5] MAIN PROCESSOR [U8] VOCODER U6] AMPLIFIER [U10] then delivered to the audio processor (U5), which includes a high speed (4FSK) modem. Data decoded by the modem is transferred to the main processor (U8) which de-encrypts the information, checks the integrity, corrects the wrong bits and extract the audio information form the received frame. The portion of the data received, error free, is moved to the vocoder (U6). The vocoder re-builds the audio from the compressed data then applies filter it, adjust the volume SMARTRUNK SYSTEMS, INC. 10 and fed it to the audio power amplifier (U10). 4.3.2. DIGITAL TX AUDIO: The AF signal from the internal 4.3. Transmitter System 4.3.1. ANALOG TX SIGNAL AMPLIFIER [U12] AUDIO PROCESSOR [U5] VOCODER [U6] TRANSMITTER [U1] VC TXCO [Y1] The AF signal from the internal microphone (MK1) or external microphone (J5) are processed as differential signal, then it is conditioned and transformed into common mode by the microphone pre-amplifier (U12). The result of the conditioned inband filtered signal is fed to the Audio Processor (U5), which provides audio compander, emphasize, limitation, encryption, etc. The high audio band of the signal from 300 to 3500 Hz are directly fed to the transmitter (U1), which performs a direct modulation of a generated carrier. Low frequency signaling audio are fed directly to Y1 VC TXCO main clock generator and U1 with a corresponding balance controlled by software. ST-2112D SM R 1.2 AUDIO PROCESSOR [U5] VC TXCO [Y1] MAIN PROCESSOR [U8] TRANSMITTER [U1] microphone (MK1) or external microphone (J5) are fed directly to the vocoder chip (U6) which perform the data codification, delivering the digitized and encoded audio as digital frames which are processed by the Main Processor U8, which add a FEC (Frame Error Correction), encrypt the information and add the user related information as user ID, etc. The final data frame is fed to the Audio Processor (U5) which has a built in modem, which operates for FDMA or TDMA signals, controlling the modulation of the Transmitter (U1) through the VC TXCO for DC to low frequencies and the direct modulation for higher frequencies. 4.3.3. Drive and Final Amplifier Stages Final RF is amplified on Q2 (2SC3356) then filtered to be fed to Q3 (2SK3475) then finally amplified by Q1 (2SK3476) up to 5 watts output power. The transmit signal then passes through the antenna switch D1 (BAR63) and is low-pass filtered to suppress harmonic spurious radiation before delivery to the antenna SMARTRUNK SYSTEMS, INC. 11 4.3.4. Automatic Transmit Power Control The RF power detector (RB705D) detects transmitted feedback then sends the readout to audio processor U5 (CMX-7141). Audio amplifier compares the transmitted power against the referred level stored on current channel memory adjusting the power control level generated as reference by one DAC output on the same Audio processor (U5) then amplified by U2 (MCP6241U) controlling the gate current on Q1 and Q17. Evenly when power level is adjusted by software on three levels (Hi, Med, Lo) the power value can be adjusted to any desired value between zero and 5Watts by the alignment software. Notes: ST-2112D SM R 1.2 SMARTRUNK SYSTEMS, INC. 12 5. RC-2112 ALIGNMENT 5.1. Introduction The ST-2112 series is carefully aligned in factory for the specified performance, across the frequency range depending for each version. Realignment should therefore not be necessary except in the event of a component failure, or altering version type. All component replacement and service should be performed only by an authorized SmarTrunk representative, or the warranty policy may be void. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently are placed, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized SmarTrunk service technicians who are experienced with the circuitry and fully equipped for repair and align. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Smartrunk service technicians realign all circuits and make complete performance checks to ST-2112D SM R 1.2 ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, SmarTrunk reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely necessary. 5.2. ALIGNMENT: The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from SMARTRUNK SYSTEMS, INC. 13 all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented. Required Test Equipment RF Signal Generator with calibrated output level at 1 GHz Deviation Meter (linear detector) In-line Wattmeter with 5 % accuracy at 1 GHz 50 Ohm RF Dummy Load with power rating 10W at 1 GHz 8 Ohm AF Dummy Load (Attention: Audio output is BTL output) Regulated DC Power Supply (standard 7.5 V DC, 3 A) Frequency Counter with 0.2 ppm accuracy at 1GHz Audio Generator AC Voltmeter DC Voltmeter UHF Sampling Coupler IBM PC / compatible Computer with Microsoft® Windows® XP or later operating system SmarTrunk SDR Programming software (version 1.0.2 or later) USB A/B Programming Cable 5.3. transmission, except where specified otherwise. Correct alignment is not possible with an antenna. After completing one-step, read the following steps to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 68°F and 86 °F (20°C ~ 30 °C). When the transceiver is brought into the shop from hot or cold air, it should be required to wait few minutes to come to room temperature before alignment. Whenever possible, alignments should be made with oscillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment procedure are based on 0 dBm EMF = 1 mV. 5.3.1. GENERAL ALIGNMENT CONSIDERATIONS: Alignment Procedure Alignment Precautions Preparation & A 50-Ohm RF Dummy Load and inline wattmeter must be connected to the main antenna jack in all procedures that request for ST-2112D SM R 1.2 Evenly if the radio is powered off, the alignment software will detect it, but some of the test cannot be performed correctly. Please be sure you turn the radio on before continue with this alignment procedure. SMARTRUNK SYSTEMS, INC. 14 In case the battery has not enough charge, the test will be aborted by the software. Please ensure the battery has more than 50% of remaining charge to complete the test. 5.4. MAIN RADIO ALIGNMENT Before setup any parameter, run SDR programming software then select Radio Alignment from top bar menu. If the radio isn’t connected, then the program will be timed out after 20 seconds. As soon as the radio is detected, actual radio parameters are loaded. Once the radio is connected, a new screen pops up showing all alignment parameters. The software downloads actual alignment parameters stored into radio memory, so the information displayed on each alignment step is the real value form the previous alignment. The radio also stores in a special memory area, original values assigned in factory. You can go back to those values anytime for any particular alignment step. In case the radio is password protected, dealer password is required to access to this alignment menu. At any time, press to end the alignment procedure then the radio will returns to alignment menu. A complementary message will be displayed on the time the software detects the radio connected to USB port on the computer. For any transmit related alignment parameter, low power will be used. 5.5.

The RF parameters are typed on the alignment software to facilitate the alignment within all radio band avoiding special programming of the radio before start alignment procedure. All parameters can be aligned without relationship to any other, so there is no an order to align. On this way, you can adjust only the desired parameter, avoiding to waste time realigning other parameters than required. Before proceed to align any parameter, a desired frequency must be loaded into both TX and RX. Evenly when the radio has stable characteristics for all bandwidth, it is recommendable to align on middle of the radio working band. 5.5.1.
