70-0671 Theory of operation The 70-0671 unit is made up of four major sections: the RF Section, the PA Section, and the Logic Section and the Display section. RF SECTION The RF Section consists of a frequency synthesizer, a transmit modulator, a receiver, and receive audio amplifier circuits. SYNTHESIZER Radio frequency signals for transmission and receiver injection are produced by voltage-controlled oscillators (VCO’s) in a Phase-Lock Loop (PLL) configuration. •Voltage Controlled Oscillator In this radio, VCO’s are used -Q706 operates in transmit mode to generate transmit frequencies and receive mode to receive injection frequencies. In each mode, the output of the buffer is amplified by IC703. RF signal at receiver injection frequency ( Fc + 10.7MHz ) is applied from the LO amplifier IC704 and Q717 in the receiver circuit. RF signal from Q708 is amplified further by the PA portion. When the frequency of the VCO output drifts away from the desired value, the loop adjusts the steering voltage to compensate. A single VCO tank can tune across the entire channel spread (6MHz for A Band, B-Band, and 8MHz for C Band). Resonance of each VCO tank is voltage-tuned by varactor diodes D701 and D705 respectively. Loop steering voltage applies reverse bias to all these varactor diodes simultaneously. As steering Voltage increases, varactor diode capacitance decreases : thus, net capacitance in each tank decreases, which increases resonant frequency of the tanks. •Loop Dividers The amplitude of the VCO signal from IC705 for TX and RX are sufficient to feed prescaling frequency divider, IC701, which applies an output pulse to once every 64 or 65 input cycles. Additional frequency division is also performed within IC701 to produce 2.5/5.0/6.25KHz. X701 is a temperature-compensated crystal oscillator that produces a reference frequency of exactly 12.8MHz. The reference frequency is divided by IC701 to produce 2.5/5.0/6.25KHz that is 13.compared to the down-counted 2.5/5.0/6.25KHz sample of VCO output. Normally the loop response is slowed enough by the active filter to block 2.5/5.0/6.25KHz reference noise and prevent loop correction of voice modulation during transmit. Higher active filter rolloff frequency is selected by the microcomputer system on the Logic Board when the radio changes channels or it is keyed and unkeyed, by a logic low applied to the base of Q705. This increase in loop response speeds locking time. A connection from an intermediate point in the phase/frequency comparator in IC701 is made at pin 7. When the loop is out of lock, the down-counted VCO sample is not in phase with the 2.5/5.0/6.25KHz reference and low going pulses appear here, which produce a logic low at pin 7. This logic low is applied to Q710 through Q709 to switch to Q505. Q505 then clamps off bias to transmit PA preamplifier Q501 to prevent emission of erratic signals generated by the uncontrolled VCO. RECEIVER •Preselector Through K501 relay in the PA, RF signals are routed to the receiver input. Signals at Image frequencies and frequencies far removed from the desired channel are rejected by a Preselector comprised of eight top-coupled, parallel tanks: L201, L202, L203, L204, L205, L206,L207 and L208. No tuning of these tanks is required for the entire channel frequency spread. Q201 provides adequate gain to overcome preselector signal losses and maximize receiver sensitivity. •Injection First Local Oscillator signal ( Fc + 10.7MHz ) is synthesized by the phase-lock loop and applied to Q717. No alignment for the first local oscillator signal is required. •First Mixer To maximize intermodulation immunity, a balanced configuration is utilized for the first mixer stage. High injection is applied to L210-primary and preselector output is applied to its secondary center tap. A diode double balanced mixer using quad-diode D202 is employed. High injection is applied to the push-pull input of the mixer. Some of this signal appears at mixer output, but most is lost because L209 is designed to operate at the 10.7 MHz first IF frequency. •First IF Mixer output is applied to Q203. L215 tunes to match the input impedance of the 10.7MHz crystal filter XF201 which reject signals outside the channel bandwidth. L215 and L217 match the input or output of XF201. Q204 amplifies the first IF signal at least 20dB, and it is coupled to second IF IC201. • Second IF IC201 contains all second IF circuitry, a quadrature demodulator, and a threshold gate. X201 and circuitry in IC201 generate second LO injection of 10.245MHz. A double-balanced mixer, that cancels both input signals internally is utilized so that additional tuned circuits at its output are not needed. Mixer output signal of 455KHz ( IC201 pin3 ) is bandpass filtered further by CF201 and CF202 then superamplified ( 100 + dB ) by the second IF amplifier/limiter within IC201 ( pin 5 ). •Demodulation The quadrature detector in IC201 is another double-balanced mixer to which limiter output is applied. Its second input is taken from 455KHz tank CD201, which is also fed with limiter output ( IC201 pin10 ). Frequency deviation from carrier center will cause phase difference between the two demodulator inputs, which produces output. Preamplified recovered audio appears at demodulator output pin 9. •Audio Recovered audio from IC201 is routed to audio processor IC401. IC401 controls the amplification level. The control voltage is fed via the external volume on the control unit. Output of the gain control IC401 is applied to the Audio amplifier IC202. Audio amplifier IC202 amplifies the audio signal and drives the speaker. •Squelch Audio signals at low pass filter are routed through Squelch Range RV201, which calibrates squelch-break level when squelch level is maximum (80). Signals is amplified and rectified by IC201 to produce a DC voltage that varies inversely with received RF carrier level. The DC voltage is input of a level detector IC408 and detector output is Q405 an open collector …

70-0671 Alignment Procedure SETUP 1 Remove the six securing screws from the bottom cover , and the cover itself. 2 Connect a resistive 50 Ω RF load and wattmeter to Antenna Connector J502. 3 Connect 13.4V DC power to transceiver J505. 4 Connect a 3.2 Ω, 20W resistor to pins 4 and 6 of the Accessory Plug. The jumper between pins 5 and 6 must be temporarily removed to make this connection. The resistor serves as a constant load to replace the speaker’s inconsistencies. CAUTION:Both speaker terminals are LIVE. Never ground either one. Connect grounded receive-audio measuring-equipment to only one side of the speaker, and chassis ground. Normally, voltage measurement will be half of true values. 5 Turn the radio on (Push on and Push off switch), set the VOLUME control to a mid-position. Connect the Programmer to Programming Port Mic Jack J302. Upload the radio programming Data-Packet into the Programmer and initiate its Remote Control Mode. Refer to the appropriate manual for details. SYNTHESIZER ALIGNMENT •VCO Resonance 1 Select the Remote Control Mode of the Programmer and enter the following test frequencies: A-Band B-Band C-Band RX Frequency 30.00 36.00 42.00 MHz TX Frequency 30.00 36.00 42.00 MHz 2 Adjust Channel RX Tank L713 for 1.5V DC at VC (VCO Steering) . 3 Active transmit mode (using the programmer ) and adjust TX Tank L702 for 1.5V DC at VC (VCO Steering) . •Reference Oscillator 4 Initiate transmit on any channel. Measure transmitted RF carrier frequency without modulation and, if necessary, adjust REFERENCE OSCILLATOR X701 for carrier frequency to within ±30Hz of channel frequency. PA MODULE ALIGNMENT The 70-0671 should be adjusted to have a 6 MHz channel spread (8 MHz C-Band) at 110W. To do so : 1 Change the TX test frequency to the desired frequency. 2 Activate transmit mode and measure RF power at Antenna connector J502. Set RF output power to 110W at J502 using the programmer. MODULATOR ALIGNMENT •Modulation Limiting 1 Disconnect the hand microphone from its front panel Mic Jack J302. Apply 3Vrms of 1000Hz signal to pin 1 of Mic Jack J302, then initiate transmit. 2 Measure total carrier deviation and, if needed adjust modulation limiting to obtain ±5KHz (wide) or ±2.5KHz (narrow) using the programmer. •Microphone Gain 3 No alignment for Microphone gain is required. •CTCSS/DCS 4 Remove the 1KHz audio signal from Mic Jack J302. 5 Add 250.3Hz CTCSS tone to the transmit test by testing frequency using the programmer. 6 Adjust CTCSS deviation to ±750 Hz ± 10 Hz (wide) or ± 375 Hz ± 10 Hz (narrow) deviation using the programmer. 7 Change 67.0 Hz CTCSS tone to the transmit test by testing frequency using in the programmer. 8 Adjust RV401 for ±750 Hz ± 100 Hz (wide) or ± 375 Hz ± 100 Hz (narrow) deviation. 9 Change the transmit DCS code +023 to the transmit test by testing frequency using the programmer. 10 Adjust RV401 so that modulation waveform from modulation analyzer matches the correct waveform shown in Figure 2-1. 11 Change 250.3 Hz CTCSS tone to the transmit test by testing frequency using the programmer. Carefully adjust RV401 for ± 750 Hz ± 10 Hz (wide) or ± 375 Hz ± 10 Hz (narrow) deviation. • DTMF 12 Clear the CTCSS tone, then initiate transmit test by testing frequency using the programmer. 13 Adjust DTMF deviation to ± 2.0KHz ± 10 Hz (wide) or ± 1KHz ± 10 Hz (narrow) deviation using the programmer. CORRECT INCORRECT INCORRECT Figure 2-1 Modulation Waveforms RECEIVER ALIGNMENT 1 Change the RX test frequency to 33.0 MHz for A-Band radios, 39.0 MHz for B-Band , 46.0 MHz for C-Band. •First Injection 2 No adjustment for first injection is required. •Preselector Alignment 3 No adjustment for the preselector (L201, L202, L203, L204, L205, L206, L207,and L208 ) is required. •Quadrature Detector 4 No adjustment for the quadrature is required. •First IF 5 Apply enough modulated ( by 1KHz tone at ± 3KHz (wide) or ± 1.5KHz (narrow) deviation ) on-channel RF signal to maintain 12 to 15 dB SINAD. Adjust L215, and L217, L803 and L804 for maximum SINAD, reducing the RF signal generator output as necessary to stay between 12 and 15 dB SINAD. NOTE: Do not adjust L801 or L802 unless appropriate test equipment is available for performing the “Noise Blanker Tuning’’ steps below. Normally, these coils are tuned for optimum sensitivity as are L803 and L804, then are retuned slightly for optimum noise blanker effectiveness. If the required test equipment is not avai- lable, skip steps 6 through 14. If coils L801 or L802 were replaced, they may be tuned for best sensitivity after adjustment of L215, L217, L803 and L804. Noise blanker performance specifications, however, may not be met. •Noise Blanker Tuning This procedures requires the additional test equipment shown in Table 2-2. 6 Adjust the pulse generator to obtain a 10 nsec wide pulse, as shown in Figure 2-2. Set the pulse period controls to obtain 200 u secbetween pulses(the pulse period is easier to observe on an oscilloscope if the pulse width is temporarily increased by about 10 times.) 7 Temporarily disable the pulse generator. 8 Using coax cable of minimum convenient length, connect the pulse generator, the RF signal generator, and the radio to the two-way power divider. 9 Disable the noise blanker by placing SW801 to the OFF position. 10 Apply an on-channel signal to obtain12dB SINAD, then increase the RF generator output by 40dB. 11 Enable the pulse generator to produce the 10nsec pulses. Adjust pulse amplitude to return SINAD reading to 12 dB. 12 Switch SW801 to the ON position. The SINAD reading should improve. 13 Reduce the RF generator output until a 12 dB SINAD reading is obtained. 14 Using a non-metallic tool, slowly tune L801(clockwise or counter-clockwise, as required) for best SINAD. The amount of L801 adjustment required should be slight. Tune L802 in the same manner. Repeat this step. Noise blanker tuning is complete.
