CIRCUIT DESCRIPTION

RECEIVER CIRCUITS
4-1-1
ANTENNA SWITCHING CIRCUIT
The 1st IF signal is applied to two crystal filters (FI1 and FI3) to suppress out-of-band signals. The filtered 1st IF signal is applied to the IF amplifier (Q14), then applied to the 2nd mixer circuit (IC1, pin 16).
Received signals passed through the low-pass filter (L1, L2, C1–C5). The filtered signals are applied to the 1/4 λ type antenna switching circuit (D1, D2, D8, L15, C76).
4-1-4
The antenna swtiching circuit functions as a low-pass filter while transmitting. However, its impedance becomes very high while D2 and D8 are turn ON. Thus transmit signals are blocked from entering the receiver circuits. The antenna switching circuit employs a 1/4 λ type diode swtiching system. The passed signals are then applied to the RF amplifier circuit.
4-1-2
The 1st IF signal from the IF amplifier is applied to the 2nd mixer section of the FM IF IC (IC2, pin 16), and is mixed with the 2nd LO signal to be converted to a 450 kHz 2nd IF signal.
RF CIRCUIT
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals.
The FM IF IC 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.
The signals from the antenna switching circuit are applied to the limitter (D50), and are then passed through the bandpass filter (D9, L16, C80). The filtered signals are amplified at the RF amplifier (Q12), then applied to the 1st mixer circuit after out-of-band signals are suppressed at the bandpass filter (D11, D12, L19, C91–C97).
The 2nd IF signal from the 2nd mixer (IC2, pin 3) passes through a ceramic filter (FI2) to remove unwanted heterodyned frequencies. It is then amplified at the limiter amplifier (IC2, pin 5) and applied to the quadrature detector (IC2, pins 10, 11) to demodulate the 2nd IF signal into AF signals.
D9, D11, D12 employ varactor diodes that track the bandpass filters and are controlled by the T1–T3 signals from the D/A convertor (IC10, pins 2, 3, 10). These diodes tune the center frequency of an RF passband for wide bandwidth receiving and good image response rejection.
4-1-3
2ND IF AND DEMODULATOR CIRCUITS
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double conversion superheterodyne system (which converts receive signal twice) improves the image rejection ratio and obtain stable receiver gain.
4-1-5
AF CIRCUIT
The AF amplifier circuit amplifies the demodulated AF signals to drive a speaker. AF signals from the FM IF IC (IC2, pin 9) are applied to the analog swtich (IC4, pin 1) via the AF filter circuit (IC3b, pins 6, 7). The output signals from pin 2, 3 are passed through the low-pass filter (IC3d, pins 13, 14), and are then applied to the analog swtich (IC4, pin 9, 10) again. The signals from the IC4, pin 11 are applied to the AF power amplifier (IC5, pin 4) after passing through the D/A convertor (IC10, pins 12, 11).
1ST MIXER AND 1ST IF CIRCUITS
The 1st mixer circuit converts the received signal to a fixed frequency of the 1st IF signal with a PLL output frequency. By changing the PLL frequency, only the desired frequency will pass through two crystal filters at the next stage of the 1st mixer. The signals from the RF circuit are mixed at the 1st mixer (Q13) with a 1st LO signal coming from the VCO circuit to produce a 21.70 MHz 1st IF signal.

The AF signals are applied to the AF power amplifier circuit (IC5, pin 4) to obtain the specified audio level. The amplified AF signals, output from pin 10, are applied to the internal speaker (SP1) via the speaker jack (CHASSIS unit; J3) when no plug is connected to the jack.
The audio signals (SHIFT) change the reactance of D37 to modulate an oscillated signal at the VCO (Q50, D38). The oscillated signal is amplified at the LO (Q6) and buffer (Q4) amplifiers, then applied to the TX/RX switch circuit (D3, D4).
4-1-6
4-2-3
SQUELCH CIRCUIT
A squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch switches the analog swtich. A portion of the AF signals from the FM IF IC (IC2, pin 9) are applied to the active filter section (IC2, pin 8) where noise components are amplified and detected with an internal noise detector. The trigger circuit converts the detected signals to a HIGH or LOW signal and applies this (from pin 13) to the CPU (IC8, pin 19) as the NOIS signal. When the CPU receives a HIGH level NOIS signal, the CPU controls the RMUT line to cut the AF signals at the analog swtich IC (IC4). At the same time, the AFON line controls the AF regulator circuit (Q15, Q16) to cut out the VCC power source for the AF power amplifier (IC5).

TRANSMITTER CIRCUITS
4-2-1
MICROPHONE AMPLIFIER CIRCUIT
The bias current of the drive (Q2) and power (Q1) amplifiers is controlled by the APC circuit to stabilize the output power.
4-2-4
APC CIRCUIT
The APC (Automatic Power Control) circuit (IC3a, Q37) protects drive and power amplifiers from excessive currents and selects HIGH or LOW output power. The output voltage from the power detector circuit (D32, D33) is applied to the differential amplifier (IC3a, pin 2), and the “T3” signal from the D/A convertor (IC10, pin 10) is applied to the other input for reference.
The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis from the microphone to a level needed for the modulation circuit.
When the driving current increases, the input voltage of the differential amplifier (IC3a, pin 2) will be increased. In such cases, the differential amplifier output voltage (pin 1) is decreased to reduce the drive current.
The AF signals from the microphone are applied to the microphone amplifier circuit (IC3c, pin 10). The amplified AF signals are passed through the low-pass filter circuit (IC3d, pins 13, 14) via the analog swtich (IC4, pins 4, 3). The filtered AF signals are applied to the modulator circuit after passing through the analog swtich (IC4, pins 8, 9).
4-2-2
DRIVE/POWER AMPLIFIER CIRCUITS
The signal from the VCO circuit passes through the TX/RX swtiching circuit (D3) and is amplified at the pre-drive (Q3), drive (Q2) and power (Q1) amplifiers to obtain 5.5 W of RF power (at 7.2 V DC/typical). The amplified signal passes through the low-pass filter (L4, C278, C287), and then applied to the antenna swtiching circuit (D1). The signal is applied to the antenna connector (J1) after being passed through the low-pass filter (L1, L2, C1–C5).
Q37 is controlled by the TXC signal from the CPU (IC8, pin 55) to select HIGH or LOW output power.
MODULATION CIRCUIT
The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signals.

PLL CIRCUITS
VOLTAGE LINE
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.
VCC
The voltage from the attached battery pack.
CPU5
Common 5 V converted from the VCC line by the CPU5 regulator (IC12). The output voltage is applied to the CPU (IC8), EEPROM (IC7) and reset IC (IC11).
SW5V
Common 5 V converted from the VCC line by the SW5 regulator circuit (Q55, Q57, D39). The output voltage is applied to the T5, R5, PS5 and VCO5 regulator circuits, D/A convertor (IC10, pin 16), etc.
VCO5
Common 5 V converted from the SW5V line by the VCO5 regulator circuit (Q11) using the LO (Q6) and buffer (Q4, Q5) amplifiers. The VCO5 regulator circuit is controlled by the PSVCO line from the CPU (IC8, pin 62).
PS5
Common 5 V converted from the SW5V line by the PS5 regulator circuit (Q54) using the analog switch (IC14, pin 14) and APC controller (Q37). The PS5 regulator circuit is controlled by the PS5C line from the CPU (IC8, pin 63).
R5
5 V for receiver circuits converted from the SW5V line by the R5 regulator circuit (Q21) using the 2nd IF IC (IC2, pin 4), RF (Q12) and IF (Q14) amplifiers, etc. The R5 regulator circuit is controlled by the R5C line from the CPU (IC8, pin 53).
T5
5 V for the transmitter circuit converted from the SW5V line by the T5 regulator circuit (Q22) using the pre-drive amplifier (Q3). The T5 regulator circuit is controlled by the T5C line from the CPU (IC8, pin 54).
The PLL circuit contains the VCO circuit (Q50, D38). The oscillated signal is amplified at the LO (Q6) and buffer (Q5) amplifiers and then applied to the PLL IC (IC1, pin 6). The PLL IC contains a prescaler, programmable counter, programmable divider, phase detector, charge pump, etc. The entered signal is divided at the prescaler and programmable counter section 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, its phase changes from the reference frequency, causing a lock voltage change to compensate for the drift in the oscillated frequency. A portion of the VCO circuit is amplified at the LO (Q6) and buffer (Q4) amplifiers and is then applied to the receive 1st mixer or transmit pre-drive amplifier circuit via the TX/RX swtiching diode (D3, D4).

TONE SQUELCH CIRCUIT
DESCRIPTION
LINE
A portion of the detected audio signals from the “DET” line are passed through the tone filter (Q53). The filtered signal is then applied to the CPU (IC1, pin 94) via the “CTCIN” signal, and is compared with the programmed tone signal. The CPU (IC1) outputs control signals as “CTCC” signal to the AF mute and AF regulator circuits to open the squelch when a matched tone signal is received.

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.
