REPAIR NOTES 1. 2. 3. 4. 5. 6. 7.

Make sure a problem is internal before disassembling the transceiver. DO NOT open the transceiver until the transceiver is disconnected from its power source. DO NOT force any of the variable components. Turn them slowly and smoothly. DO NOT short any circuits or electronic parts. An insulated turning tool MUST be used for all adjustments. DO NOT keep power ON for a long time when the transceiver is defective. DO NOT transmit power into a signal generator or a sweep generator. ALWAYS connect a 40 dB to 50 dB attenuator between the transceiver and a deviation meter or spectrum analyzer when using such test equipment. 8. READ the instructions of test equipment thoroughly before connecting equipment to the transceiver.

SECTION 4 CIRCUIT DESCRIPTION 4-1-3 2ND IF AND DEMODULATOR CIRCUITS (MAIN UNIT)

4-1 RECEIVER CIRCUITS 4-1-1 ANTENNA SWITCHING CIRCUIT (MAIN UNIT)

The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double convertion superheterodyne system (which converts receive signal twice) improves the image rejection and obtain stable receiver gain.

The antenna switching circuit functions as a low-pass filter while receiving and as resonator circuit while transmitting. The circuit does not allow transmit signals to enter receiver circuits.

The 1st IF signal is applied to a 2nd mixer section of the FM IF IC (IC170, pin 16). The signal is then mixed with a 2nd LO signal for conversion into a 450 kHz 2nd IF signal.

Received signals from the antenna connector pass through the low-pass fileter (L80–L82, C80–C86) and antenna switching circuit (D52, D90, D91). The filtered signals are then applied to the RF amplifier circuit (Q90).

IC170 contains the 2nd mixer, limiter amplifier, quadrature detector and active filter circuits. A 21.25 MHz 2nd LO signal is produced at the PLL circuit using the reference frequency.

4-1-2 RF AND 1ST MIXER CIRCUITS (MAIN UNIT) The 1st mixer circuit converts the received signals to a fixed frequency of the 1st IF signal with a PLL output frequency. By changing the PLL frequency, only the desired frequency will be passed through a pair of crystal filters at the next stage of the 1st mixer.

The 2nd IF signal from the 2nd mixer (IC170, pin 3) passes through ceramic filters (FI170) to remove unwanted heterodyned frequencies. It is then amplified at the limiter amplifier section (IC170, pin 5) and applied to the quadrature detector section (IC170, pins 10 and 11) to demodulate the 2nd IF signal into AF signals.

The signals from the antenna switching circuit are passed through the tunable bandpass filter (D92, D93) and amplified at the RF amplifier (Q90). The amplified signals are passed through another tunable bandpass fileter (D130), and then applied to the 1st mixer circuit (Q150).

4-1-4 AF CIRCUIT (MAIN UNIT) AF signals from the FM IF IC (IC170, pin 9) are fed to the analog switch (IC260). The AF signals (detected signals) are passed through the analog switch (IC260, pins 2 and 1) and are then applied to the active low-pass filter (IC200c, pin 9).

The filtered signals are mixed at the 1st mixer (Q150) with a 1st LO signal coming from the PLL circuit to produce a 21.7 MHz 1st IF signal. The 1st IF signal is passed through two crystal filters (FI150, FI151) and is then amplified at the IF amplifier (Q151).

The filtered AF signals are applied to and adjusted audio level at the [VOL] control (VR unit; R500). The level controlled signals are passed through the AF mute switch (Q280) which is controlled by “IVOLM” signal from the CPU (IC9, pin 31). The passed signals are applied to the AF power amplifier (IC280, pin 4), and then output to the internal speaker or [EXT SP] jack after being passed through the de-emphasis circuit (R286, C285) to obtain the –6 dB/octave frequency characteristics.

4-1-5 SQUELCH CIRCUIT (MAIN UNIT)

4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS (MAIN UNIT)

The noise squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch.

The signal from the VCO circuit passes through the transmit/receive switching circuit (D50, D51) and is applied to the buffer-amplifier (Q50). The amplified signal is amplified by the pre-driver (Q53) and the power amplifier (Q54) to obtain 5 W of RF power (at 7.2 V). The amplified signal passes through the antenna switching circuit (D52), and low-pass filter (L80–L82, C80–C86) and is then applied to the antenna connector.

A portion of the AF signals divided by C175 from the FM IF IC (IC170, pin 9) are applied to the D/A convertor (IC190, pin 16) to adjust amplitude. The signals from the D/A convertor (IC190, pin 15) are applied to the active filter section (IC170, pin 8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from IC170 (pin 14) as the “NOISV” signal.

The bias current of the pre-driver (Q53) and the power amplifier (Q54) is controlled by the APC circuit to stabilize the output power.

The “NOISV” signal from IC170 (pin 14) is applied to the CPU (IC360, pin 90). The CPU compares the set squelch level voltage and “NOISV” signal voltage to control the squelch output.

4-2-4 APC CIRCUIT (MAIN UNIT) The APC (Automatic Power Control) circuit provides stable output power from the power amplifier even when the input voltage or temperature changes, and selects HIGH, MIDDLE or LOW (1W type selects HIGH or LOW) output power. The APC circuit consists of a power detector and APC control circuits.

4-2 TRANSMITTER CIRCUITS 4-2-1 MICROPHONE AMPLIFIER CIRCUIT (MAIN UNIT)

• POWER DETECTOR CIRCUIT (MAIN UNIT) The power detector circuit (D80, C87) detects the transmit output power level and converts it to DC voltage as the “TDETV” signal. The detected signal is applied to the APC control circuit.

The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis characteristics from the microphone to a level needed for the modulation circuit. The AF signals from the microphone are passed through the pre-emphasis circuit (R253, C254) and are then applied to the microphone amplifier (IC200b). The amplified AF signals are applied to analog switch (IC260, pin 5).

• APC CONTROL CIRCUIT (MAIN UNIT) The “TDETV” signal from the power detector circuit is applied to the CPU (IC360, pin 92) to control the input voltage of the pre-driver (Q53) and the power amplifier (Q54). When the output power changes, the CPU (IC360) outputs APC control signal to the D/A converter (IC190). And then “PCON” signal from the D/A converter controls the APC controller (IC50) to provide stable output power.

The AF signals are amplified again at the limiter-amplifier (IC200a) and then passed through the low-pass filter (IC200d, pins 10 and 8). The filtered audio is applied to the modulation circuit as the “MOD” signal.

4-2-2 MODULATION CIRCUIT (MAIN UNIT) The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signals. The audio signals “MOD” change the reactance of D22 and D23 to modulate an oscillated signal at the VCO circuit (Q21, Q22, D22, D23). The oscillated signal is amplified at the buffer-amplifiers (Q23, Q24).

4-3 PLL CIRCUIT (RF UNIT)

4-4 POWER SUPPLY CIRCUITS

A PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL output compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by the divided ratio (N-data) of a programmable divider.

The voltage from the attached battery pack.

VCC

The same voltage as the HV line (battery voltage) which is controlled by the power switch (RF unit; [OFF/VOL] control).

CPU5V

Common 5 V converted from the VCC line by the CPU5V regulator circuit (IC220). The output voltage is applied to the CPU (MAIN unit; IC360), REG5V regulator, etc.

5V

Common 5V converted from the VCC line by the 5V regulator circuit (Q223–Q225). The output voltage is applied to the D/A converter (IC190) and PLL IC (IC1), etc.

R5V

Receive 5V converted from the 5V line by the R5 regulator circuit (Q221). The regulated voltage is applied to the MOD MUTE circuit (Q20, D20, D21) and receiver circuit.

V5V

Common 5V converted from the 5V line by the V5 regulator circuit (Q220). The regulated voltage is applied to the VCO circuit

T5V

Transmit 5V converted from the 5V line by the T5 regulator circuit (Q222). The regulated voltage is applied to the transmitter circuit.

The PLL circuit contains a VCO (Q21, Q22, D22, D23). The oscillated signal is amplified at the buffer-amplifiers (Q23, Q25) and then applied to the PLL IC (IC1, pin 19). The PLL IC contains the prescalers, programmable counter, programmable divider, phase selector and etc. The entered signal is divided at the prescaler and programmable counter sections by the N-data ratio from the CPU. The divided signal is detected on phase at the phase detector using the reference frequency. If the oscillated signal drifts, the phase of its frequency changes from the reference frequency, causing a lock voltage changes to compensate for the drift in the oscillated frequency. A portion of the VCO signal is amplified at buffer-amplifiers (Q23, Q24) and is then applied to the receive 1st mixer (Q150) or transmit buffer amplifier (Q50) via the TX/RX switching diode (D50, D51).
