Circuit Description Reception and transmission are switched by “RX-CNTL“ and “TX-CNTL“ lines from the CNTL Unit. The receiver uses double-conversion superheterodyne circuitry, with a 21.4 MHz 1st IF and 450 kHz 2nd IF. The 1st local is produced by a PLL synthesizer, yielding the 21.4 MHz 1st IF. The 2nd local uses a 21.850 MHz crystal oscillator, yielding the 450 kHz 2nd IF. The 2nd mixer and other cir- cuits use a custom IC to convert and amplify the 2nd IF and detect FM to obtain demodulated signals. During transmit, the PLL synthesizer oscillates at the desired fre- quency directly, for amplification to obtain RF power out- put. During transmit, voice modulation is applied to this synthesizer. Transceiver functions, such as TX/RX control, PLL synthesizer settings, and channel programming, are controlled using the MPU. Receiver Incoming RF signals from the antenna connector are de- livered to the MAIN Unit, and pass through a low-pass filter (LPF) consisting of coils and capacitors, and anten- na switching diodes D1003 and D1004 (both XB15A308) for delivery to the receiver front end. Signals within the frequency range of the transceiver are then passed through a bandpass filter consisting of T1001 and T1002 before RF amplification by Q1016 (2SC5006). The amplified RF is then bandpass filtered again by T1003, T1004, and T1005, to ensure pure in-band input to 1st mixer Q1024 (3SK320). Buffered output from the VCO Unit is amplified by Q1022 (2SC5006) and bandpass filtered by L1013, L1015, C1125, C1131, and C1134, to provide a pure 1st local signal be- tween 133.75 and 140.975 MHz for delivery to the 1st mix- er. The 22.3 MHz 1st mixer product then passes through dual monolithic crystal filter XF1001 and XF1002 (±6.5 kHz BW), and is amplified by Q1031 (2SC4400-3) and delivered to the input of the FM IF subsystem IC Q1036 (TA31136FN). This IC contains the 2nd mixer, 2nd local oscillator, limit- er amplifier, FM detector, noise amplifier, and squelch gates. The 2nd local is produced by crystal X1001 (21.850 MHz) then passes through the amplifier Q1017 (2SC4154) ,and delivered to the 2nd mixer in the IF-IC. The 1st IF is con- verted to 450 kHz by the 2nd mixer and stripped of un- wanted components by ceramic filter CF1001. Filtered signal from the ceramic filter CFa001 is applied to the limiter amplifier in the FM IF subsystem IC Q1036 (TA31136FN), and then demodulate by the FM detector in the FM IF subsystem IC Q1036 (TA31136FN). Demod- ulated receive audio from the FM IF subsystem IC Q1036 (TA31136FN) is amplified by Q1038 (2SC4154E), then the signal is through the AF switch Q1040 (BU4053BCFV), the AF amplifier Q1045 (NJM12902V) and the AF Mute switch Q1035 (BU4066BCFV). After volume adjustment by the D/A converter Q1033 (M62364FP) and the AF power amplifier Q1043 (LA4425A), the audio signal is passed to the external Speaker terminal in the accessory cable and 16-Ohm in- ternal loudspeaker. PLL Synthesizer The 1st LO maintains stability from the PLL synthesizer by using a 21.850 MHz reference signal from crystal X1001. PLL synthesizer IC Q1021 (MB15A02PFV) consists of a prescaler, reference counter, swallow counter, program- mable counter, a serial data input port to set these counters based on the external data, a phase comparator, and a charge pump. The PLL-IC divides the 21.850 MHz reference signal by 874 using the reference counter (25 kHz comparison fre- quency). The VCO output is divided by the prescaler, swallow counter and programmable counter. These two signals are compared by the phase comparator and ap- plied to the charge pump. A voltage proportional to their phase difference is deliv- ered to the low-pass filter circuit, then fed back to the VCO as a voltage with phase error, controlling and stabilizing the oscillating frequency. This synthesizer also operates as a modulator during transmit. The RX VCO is comprised of Q1027 (2SK520-K43) and D1009, D1010, D1014, D1015 (all HVC3068); it oscillates at 22.3 MHz below the receiving frequency. The TX VCO is comprised of Q1029 (2SC5006) and D1012 (both HVC3068); it oscillates at the fundamental frequency, with direct frequency-modulation using varactor diode D1016 (HVC3068). The VCO output passes through buffer am- plifier Q1022 (2SC5006) to obtain stable output. The VCO DC supply is regulated by Q1018 (2SC4154E). Synthe- sizer output is fed to the 1st mixer Q1024 (3SK320) by diode switch D1006 (DAN235U) during receive, and to drive amplifier Q1014 (2SC3357), and the RF power am- plifier Q1007 (RA35H1516M) for transmit. The reference oscillator feeds the PLL synthesizer. Transmitter Voice audio from the microphone is delivered via the MIC connector to the MAIN Unit. After passing through am- plifier Q1028 (NJM12902V), a pre-emphasis network, the D/A converter Q1033 (M62364FP) for MIC switch, the MIC mute switch Q1035 (BU4066BCFV), limiter (IDC: in- stantaneous deviation control), and LPF Q1028 (NJM12902V), the audio is adjusted for optimum devia- Circuit Description tion level and delivered to the next stage. Voice or DSC (Digital Selective Calling) encode signal in- puts from the LPF Q1028 (NJM12902V) are FM-modulat- ed in the VCO of the synthesizer. Synthesizer output, af- ter passing through diode switch D1006 (DAN235U), is amplified by driver Q1014 (2SC3357), and the RF power amplifier Q1007 (RA35H1516M) to obtain full RF output. The RF energy then passes through antenna switch D1003 (XB15A308) and a low-pass filter circuit and finally to the antenna connector. RF output power from the final amplifier is sampled by C1013 and C1019 and is rectified by D1002 (1SS321). The resulting DC is fed through Automatic Power Control- lers Q1034 (NJM2904V) to transmitter RF power amplifi- er Q1007 (RA35H1516M), thus providing positive con- trol of the power output. Generation of spurious products by the transmitter is min- imized by the fundamental carrier frequency being equal to the final transmitting frequency, modulated directly in the tra…

With a nominal battery voltage, and the transmitter properly adjusted the RF output measures: OUTPUT POWER: HIGH: 25 W CONDUCTED LOW: 1 W CONDUCTED 80.911 (d)(5) For primary supply voltages, measured in accordance with the procedures in this paragraph, greater than 11.5 volts, but less than 12.6 volts, the required transmitter output power shall be equal or greater than the value calculated below P = 4.375(v) – 35.313 (For 12V this equals 17.2W) METHOD OF MEASURING RF POWER OUTPUT Transmitter 50 ohm under test Resistive Wattmeter Power Supply K6630063X30 REPORT #: V\VERTEX USA_\1248AUT4\1248AUT4TestReport.doc Page 2 of 15 TIMCO ENGINEERING INC. 849 NW State Road 45 Newberry, Florida 32669 http://www.timcoengr.com 888.472.2424 F 352.472.2030 email: [email protected] APPLICANT: VERTEX STANDARD CO., LTD. FCC ID: TECHNICAL DATA: 80.203 (b) External Controls: The transmitter is capable of changing frequency between 156.05 – 157.425 MHz by external control. The available channels are shown in the User Manual description Channel List. These channels are preprogrammed by the manufacturer and change of frequency is inaccessible to the station operator. 80.203 (c) Five minutes continuous transmission test. The antenna was connected to a dummy load and the radio was locked in a transmit PTT mode. An external timer digital clock was used to observe the duration of the un-modulated transmission. The transmitter turned off and the radio went to receive mode at 4 minutes, 58 seconds as displayed by the external digital clock. 80.203 (n) This radio complies with the requirement for DSC capability in the 156.025-157.425 MHz band and in accordance with 80.225. 80.873; 80.956 Transmitter G3E emission capability: The transmitter was connected to 50 ohm resistive wattmeter and the frequency was set to 156.300 and to 156.800 MHz. With normal modulation, the output power displayed was 25 Watts at the high power setting and 1 watt at low power setting, consistent with previous measurements. The transmitter has been demonstrated to be capable, with normal operating voltages applied, of delivering 25 watts of carrier power into a 50 ohm resistive load over the specified frequencies. 80.911 (a) 80.956 G3E Transmissions: This ra…
