could cause a fire or electric hazard.
DO NOT reverse the polarities of the power supply when
connecting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100 mW)
to the antenna connector. This could damage the transceiver's front end.

SECTION 4 CIRCUIT DESCRIPTION
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
The antenna switching circuit toggles receive line and
transmit line. This circuit does not allow transmit signals to
enter the receiver circuits.
Received signals from the antenna are passed through the
low-pass filter (LPF: L131, L132, C131–C136) and applied
to the antenna switching circuit (D151, D152).
While receiving, no voltage is applied to D151 and D152.
Thus, the receive line and the ground are disconnected and
L151, L152, C151, C152 and C153 function as an LPF which
leads received signals to the RF circuits.
4-1-2 RF CIRCUITS
The RF circuits amplify signals within the range of frequency coverage and filters off out-of-band signals.
The signals from the antenna switching circuit are passed
through the two-stage tunable bandpass filter (BPF: D154,
D155, L154–L156, C156, C157, C159–C161, C163, C164,
C168), then applied to the RF amplifier (Q165).
The amplified signals are passed through another two-stage
BPF (D181, D182, L166, L181 C181, C182, C184–C186,
C188) to suppress unwanted signals. The filtered signals are
then applied to the 1st mixer circuit.
The 1st IF signal from the 1st mixer is passed through the
crystal filter (FI211) to suppress unwanted signals, and
amplified at the 1st IF amplifier (Q211).
The amplified 1st IF signal is applied to the FM IF IC
(IC231).
4-1-4 2nd IF AND DEMODULATOR CIRCUITS
The 1st IF signal is converted into the 2nd IF signal and
de-modulated by the FM IF IC. The FM IF IC contains
2nd mixer, limiter amplifier, quadrature detector, etc. in its
package.
The 1st IF signal from the 1st IF amplifier is applied to pin
16 of IC231, and mixed with the 30.6 MHz 2nd LO signal
coming from the doubler (Q221), to convert into the 450 kHz
2nd IF signal and output from pin 3. The 2nd IF signal is
filtered by the ceramic filters (FI231, FI232) to suppress the
heterodyne noise, then applied to IC231 (pin 5) again and
amplified at the limiter amplifier section and demodulated by
the quadrature detector.
The quadrature detector is a detection method which uses a
ceramic discriminator (X231). The demodulated AF signals
are output from pin 9.
4-1-5 AF CIRCUITS
Demodulated signals are filtered and amplified at the AF
circuits.
4-1-3 1st MIXER AND 1st IF AMPLIFIER CIRCUITS
The 1st mixer circuit converts received signals into the
1st intermediate frequency (IF) signal by mixing with local
oscillator (LO) signal. The converted 1st IF signal is filtered
at the 1st IF filter, then amplified at the 1st IF amplifier.
The signals from the two-stage BPF are converted into the
31.05 MHz 1st IF signal at the 1st mixer (Q191) by being
mixed with the 1st LO signals generated at RX VCO (Q41,
D31–D34).

1, 7), LPF (IC261 C; pins 8–10) and R801 (VR BOARD) to
control the AF output level.
The level controlled AF signals are passed through the AF
mute switch (Q411) and the de-emphasis circuit (R411,
C413) to obtain the frequency characteristic of –6 dB/oct.
The de-emphasized signals are applied to the AF power
amplifier (IC421, pin 4). The AF power amplifier provides
more than 0.3 W of audio power.

4-1-6 SQUELCH CIRCUIT
Squelch circuit mutes AF output signal when no signals are
received.
4-2-2 MODULATOR CIRCUIT
The modulation circuit modulates the VCO oscillating signal
with the audio signals from the microphone.
A portion of the AF signals from the FM IF IC (IC231, pin 9) are
applied to the IC251 to control the level, and the active filter
(R239–R241, C237, C238). The filtered signals are applied to
the noise amplifier section in the FM IF IC (IC231, pin 8) to
amplify the noise components only.
The amplified noise components are detected at the noise
detector section, and output from pin 14 as the "NOISV"
signal to the CPU (IC661, pin 32). Then the CPU outputs
"AFMS" signal from pin 84 according to the "NOISV" signal
level to control the AF mute switch (Q411).
4-2 TRANSMITTER CIRCUITS
4-2-1 MIC AMPLIFIER, SPLATTER FILTER CIRCUITS
The MIC amplifier circuit amplifies audio signals from the
microphone within +6 dB/oct pre-emphasis characteristics
and amplifies to the level needed for modulation.
The AF signals from the microphone are passed through
the microphone switch (Q461) and the microphone mute
switches (IC682 A, pins 1, 2; IC682 B, pins 5, 6). The AF
signals are then passed through the pre-emphasis circuit
(R463, C463) to obtain frequency characteristics of +6 dB/oct.
The pre-emphasized AF signals are amplified at the
microphone amplifier (IC261 B), and adjusted its level at the
microphone gain control circuit (Q653, Q654, R474, R705,
R707, R708). The level adjusted signals are applied to the
limiter amplifier (IC491 A; pins 1, 2) to limit its level via the
AF mute switch (IC481 A; pins 1, 2).
The AF signals are then passed through the splatter filter
(IC491 B; pins 6, 7) to suppress unwanted 3 kHz and higher
audio signals, then applied to the modulation circuit via the
D/A converter (IC251; pins 3, 4).
AF signals from the D/A converter (IC251, pin 3) are applied
to the modulation circuit (D39) to modulate the oscillated
signal by changing the reactance of D39 at the TX VCO (Q51,
D35–38).
4-2-3 TRANSMIT AMPLIFIERS
Transmit amplifiers amplify the TX VCO output to transmit
power level.
The TX VCO output signal is buffer-amplified by the buffer
amplifiers (Q61, Q62) and passes through the TX/RX switch
(D91). The signals from the TX/RX switch are applied to the
another buffer amplifier (Q91), pre-drive (Q101) and power
amplifier (Q111) and amplified to the transmit level.
The power amplifier output is applied to the antenna
connector (J41: CHASSIS UNIT) via the antenna switching
circuit and the LPFs.
4-2-4 APC CIRCUIT
The APC (Automatic Power Control) circuit stabilizes
transmit output power and controls transmit output power
High, Middle and Low.
The RF output signal from the power amplifier (Q111)
is detected at the power detector (D121). The detector
converts the RF signals into DC voltage, and the detected
voltage is applied to the APC amplifier (IC141, pin 3).
The transmit output power setting voltage is applied to
another input terminal of the APC amplifier (IC141, pin 1) as
the reference voltage. The APC amplifier controls the bias of
the buffer, pre-drive and power amplifiers by comparing the
detected voltage and reference voltage. Thus the APC circuit
maintains a constant output power.

4-3 PLL CIRCUITS
4-3-1 GENERAL
PLL circuits control TX and RX VCO circuits. IC1 is a
PLL IC and contains prescaler, programmable counter,
programmable divider, phase detector, charge pump in its
package.
The VCOs directly generate the transmit frequency and the
1st LO frequency for receiving. The PLL sets the divided
ratio based on the serial data from the CPU (IC661), and
compares the phase of the VCO output with the reference
oscillator's frequency (15.3 MHz) oscillated by X1.
If the oscillated signal drifts, the phase of its frequency
changes from the phase of the reference frequency, causing
a lock voltage change to compensate for the drift in the
oscillated frequency.
4-3-2 TRANSMIT LOOP
A portion of the generated signal at the TX VCO (Q51, D35–
D39) is applied to the PLL IC (IC1, pin 8) via buffer-amplifier
(Q71). The applied signal is divided at the prescaler section
and programmable divider section and is then applied to the
phase detector section.
The phase detector compares the input signal with the
reference frequency, and then outputs the control signal
(pulse-type) from pin 5 via the charge pump section. The
pulse-type signal is converted into DC voltage at the loop
filter (R17–R19, C16, C17), and then applied to the TX VCO
(Q51, D35–D39) as the lock voltage.
The phase detector compares the input signal with a
reference frequency, and then outputs the control signal
(pulse-type) from pin 5. The pulse-type signal is converted
into DC voltage at the loop filter (R17–R19, C16, C17), and
then applied to the RX VCO (Q41, D31–D34) as the lock
voltage.
4-3-3 RECEIVE LOOP
The generated signal at the RX VCO (Q41, D31–D34) is
applied to the PLL IC (IC1, pin 8) via buffer-amplifier (Q71)
and is divided at the prescaler section and programmable
divider section and is then applied to the phase detector
section.
