DANGER
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than 5 V. Such a connection
could cause a fire hazard and/or electric.
DO NOT expose the transceiver to rain, snow or any liquids.
DO NOT reverse the polarities of the power supply when
connecting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100mW)
to the antenna connector. This could damage the transceiver's front end.

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 30 dB to 40 dB attenuator between the transceiver and a deviation meter or spectrum analyzer when
using such test equipment.

CIRCUIT DESCRIPTION
4-1-1 ANTENNA SWITCHING CIRCUIT (RF UNIT)
4-1-4 2nd MIXER AND DEMODULATOR CIRCUITS
(RF UNIT)
Received signals from the antenna connector are passed
through the low-pass filter (L5, L6, C8–C12). The filtered signals are applied to the λ⁄4 type antenna switching circuit (D7,
D101, D102, L4, L206, C209, C210).
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal. A double conversion superheterodyne system (which
converts receive signals twice) improves the image rejection
ratio and obtains stable receiver gain.
The antenna switching circuit functions as a low-pass filter
while receiving. However, its impedance becomes very high
while D101 and D102 are turned ON (while transmitting).
Thus transmit signals are blocked from entering the receiver
circuits. The passed signals are then applied to the RF amplifier circuit.
The 1st IF signal from the IF amplifier (Q1) is applied to the
2nd mixer section in the FM IF IC (IC2, pin 16), and is mixed
with the 2nd LO signal to be converted into a 450 kHz 2nd IF
signal.
4-1 RECEIVER CIRCUITS
The FM IF IC contains a 2nd mixer, quadrature detector,
noise amplifier and a limiter amplifier, etc. The PLL reference
oscillator (X1) is used for the 2nd LO signal via the PLL IC
(IC1, pins 11, 9), and is applied to pin 1 of the FM IF IC (IC2).
4-1-2 RF CIRCUIT (RF UNIT)
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals.
The signals from the antenna switching circuit are amplified
at the RF amplifier (Q3) and passed through the bandpass filter (FI1) to suppress out-of-band signals. The filtered signals
are applied to the 1st mixer circuit (Q2).
The mixed 2nd IF signal is output from pin 3 and passed
through the ceramic bandpass filter (FI3) to remove unwanted heterodyne frequencies. It is then amplified at the limiter
amplifier section (IC2, pin 5) and applied to the quadrature
detector section (IC2, pins 10, 11) to demodulate the 2nd IF
signal into AF signals.
4-1-3 1st MIXER AND 1st IF CIRCUITS (RF UNIT)
4-1-5 AF CIRCUIT (RF AND MAIN UNITS)
AF signals from the FM IF IC (RF unit; IC2, pin 9) are passed
through the high-pass filter (RF unit; Q15, Q16) to remove
CTCSS signals then applied to the MAIN unit via J2 pin 10 as
the “VOL” signal.
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 desired signals will be
passed through a crystal filter at the next stage of the 1st
mixer.
The “VOL” signal (AF signals) from the RF unit is applied to
the [VOL] control (MAIN unit; R58) to control the audio level
via the volume mute switch (Q23). The level controlled AF
signals are applied to the AF power amplifier (IC9, pin 2) to
drive an internal speaker (SP1) via the [SP] jack (J1).
The signals from the bandpass filter are mixed at the 1st
mixer circuit (Q2) with a 1st LO signal coming from the VCO
circuit to produce a 21.7 MHz 1st IF signal.The 1st IF signal
is applied to a crystal filter (FI2) to suppress out-of-band signals. The filtered 1st IF signal is applied to the IF amplifier
(Q1), then applied to the 2nd mixer circuit (IC2, pin 16).

4-1-6 SQUELCH CIRCUIT (RF AND MAIN UNITS)
4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS
(RF UNIT)
(1) NOISE SQUELCH
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 amplifier circuit amplifies the VCO oscillating signal to
the output power level.
The amplified transmit signal is passed through the antenna
switching circuit (D6) and low-pass filter, and is then applied
to the antenna.
A portion of the AF signals from the FM IF IC (RF unit; IC2,
pin 9) are applied to the active filter section (RF unit; IC2, pin
8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector
section and output from pin 14 as the “SQL” signal.
The modulated transmit signal is amplified at the pre-drive
and drive amplifiers (Q8, Q201) after being amplified at the
buffer amplifier (Q7). The amplified signal is power amplified
at the power amplifier (Q202) to obtain 500 mW or
(IC–4008A) 10 mW (IC–4008MK2) of RF power.
The “SQL” signal from IC2 (pin 14) passes through J2 pin 9,
and is then applied to the CPU (MAIN unit; IC1, pin 59). The
CPU analyzes the noise condition and outputs the “RMUT”
and “AFON” signals to toggle the volume mute (MAIN unit;
Q23) and AF mute (MAIN unit; Q5, Q10, Q11) switches.
The power amplified signal is then applied to the antenna via
the low-pass filter circuits.
(2) TONE SQUELCH
The tone squelch circuit detects AF signals and opens the
squelch only when receiving a signal containing a matching
subaudible tone (CTCSS). When tone squelch is in use, and
a signal with a mismatched or no subaudible tone is
received, the tone squelch circuit mutes the AF signals even
when noise squelch is open.
4-3 PLL CIRCUITS (RF UNIT)
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.
A portion of the AF signals from the FM IF IC (RF unit; IC2,
pin 9) passes through the tone low-pass filter (MAIN unit; Q7,
Q12) to remove AF (voice) signals and is applied to the
CTCSS decoder inside the CPU (MAIN unit; IC1, pin 58) via
the “CTCIN” line to control the volume mute and AF mute
switches.
The PLL circuit consists of the VCO circuit (Q6, D4, D5). An
oscillated signal from the VCO passes through the buffer
amplifier (Q7) is applied to the PLL IC (IC1, pin16) and is
prescaled in the PLL IC based on the divided ratio (N-data).
The reference signal is generated at the reference oscillator
(X1) and is also applied to the PLL IC. The PLL IC detects the
out-of-step phase using the reference frequency and outputs
it from pin 14. The output signal is passed through the loop
filter (R45, C68) and is then applied to the VCO circuit as the
lock voltage.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
(MAIN UNIT)
If the oscillated signal drifts, its phase changes from that of
the reference frequency, causing a lock voltage change to
compensate for the drift in the oscillated frequency.
AF signals from the internal/external microphone are applied
to the microphone amplifier circuit (IC2b) via the microphone
switch (Q6). The amplified signals are passed through the
low-pass filter (IC2a) and applied to the modulation circuit in
the RF unit via J4 pin 5 as the MOD signal.
4-2-2 MODULATION CIRCUIT (RF UNIT)
The filtered audio signals from J4, pin 5 (On the MAIN unit)
are passed through the deviation adjustment pot (R50) then
applied to the modulation circuit (D4, D5) to modulate transmit signals at the VCO circuit (Q6).
The modulated signal is applied to the drive amplifier circuit.
