2-4. Audio Amplifier

The recovered audio signal obtained from IC201 is ampli-

fied and anti-aliasing filtered by IC712 (A/2), inputted to the
AINR terminal of CODEC IC (IC713), and audio processed by
DSP (IC710). The processed audio signal from AOUTR termi-
nal of IC713 is amplified and filtered by IC716 (A/2) to a suffi-
cient level. The audio signal goes to an electronic volume
(IC718) and then it passes through the amplifier (IC722), to
the input of multiplexer IC (IC717), and is amplified to drive a
loudspeaker by an audio power amplifier (IC720). The audio
output can be provided to external 4

Ω

speaker through the 6-

pin ACC connector “ES1, ES2” on the rear panel. Q711 is a
mute switch.

2-5. Squelch Circuit

The output signal from IC201 enters FM IC again, then

passed through a band-pass filter.

The noise component output from IC201 is amplified by

Q204 and rectified by D202 to produce a DC Voltage corre-
sponding to the noise level. The DC voltage is sent to the
analog port of the CPU (IC701).

IC201 outputs a DC voltage (RSSI) corresponding to the

input of the IF amplifier.

3. Transmitter Circuit

The transmitter circuit consists of the following circuits : 3-

1 microphone circuit, 3-2 modulation level adjustment circuit,
3-3 driver and final power amplifier circuit, and 3-4 automatic
power control circuit.

3-1. Microphone Circuit

The signal from the microphone passes through the mute

switch (Q901) and is then routed to the Display unit (X54-340)
and TX-RX unit (X57-658). The signal then passes through
the AGC circuit to avoid signal distortion.

This circuit consists of IC714, D711, D712, Q707, and

Q708. The AGC is operated by controlling the + and – side
levels of amplitude using the current obtained by positive and
negative detection of the amplified audio signal.

The audio signal is amplified by IC712 (B/2), input to the

AINL terminal of CODEC IC (IC713), and audio processed by
DSP (IC710). The processed audio signal from the AOUTL
terminal of IC713 is amplified and filtered by IC716 (B/2), and
amplified by the summing amplifier IC719 (B/2).

3-2. Modulation Level Adjustment Circuit

The output of the summing amplifier IC719 (B/2) is passed

to an electronic volume (IC718) for maximum deviation ad-
justment before being applied to a varactor diode in the volt-
age controlled oscillator VCO.

3-3. Driver and Final Power Amplifier Circuit

The transmit signal is generated by the TX VCO (Q507),

amplified by Q513 and Q 515. This amplified signal is ampli-
fied by Q1, Q2, Q3, Q4, and Q5. And this signal is passed to
the FINAL stage. The RF power amplifier consists of MOS
FET transistor.
