CIRCUIT DESCRIPTION
1. Overview
3. Receiver System
This transceiver is VHF/FM portable transceiver designed
to operate in the frequency range of 136 to 174MHz.
3-1. RF unit
An incoming RF signal from the antenna terminal is
passed through the antenna switch (D106, D107, D211 and
D213 are off) and then the bandpass filter (L215, L216). The
bandpass filter is adjusted by a variable capacitor. The input
voltage to the variable capacitor is regulated by the voltage
output from the D/A converter (IC605). The signal is amplified by RF amplifier (Q207), and passed through the bandpass filter (L211, L214).
The resulting signal is applied to the first mixer (Q206),
where it is mixed with the first local oscillator signal output
from the frequency synthesizer to produce the first IF
(59.85MHz).
2. Circuit Configuration by Frequency
The receiver is a double-conversion superheterodyne with
a first intermediate frequency (IF) of 59.85MHz and a second
IF of 455kHz. Incoming signals from the antenna are mixed
with the local signal from the PLL to produce the first IF of
59.85MHz.
This is then mixed with the 59.395MHz second local oscillator output to produce the 455kHz second IF. This is detected to give the demodulated signal.
The transmit signal frequency is generated by the PLL
VCO, and modulated by the signal from the microphone. It is
then amplified and sent to the antenna.
The first IF signal is passed through a four-pole monolithic
crystal filter (XF200) to remove a adjacent channel signal. The
filtered first IF signal is amplified by the first IF amplifier
(Q205) and then applied to the lF system IC (IC200). The IF
system IC provides a second mixer, second local oscillator,
limiting amplifier, quadrature detector and RSSI (Received
Signal Strength Indicator). The second mixer mixes the first
IF signal with the 59.395MHz of second local oscillator output
(crystal unit X200) and produces the second IF signal of
455kHz.
The second IF signal is passed through the ceramic filter
(CF201 : Wide, CF200 : Narrow) to more remove the adjacent
channel signal. The filtered second IF signal is amplified by
the limiting amplifier and demodulated by the quadrature detector with ceramic discriminator (CD200). The demodulated
signal is routed to the audio circuit.

CIRCUIT DESCRIPTION
3-3. Wide/Narrow switching circuit
Wide and Narrow settings can be made for each channel
by switching the ceramic filters CF201 (Wide), CF200 (Narrow). The Wide (low level) and Narrow (high level) is output
from IC502.
When a Wide (low level) is selected, Q200 (N-ch) turn off
and Q200 (P-ch) turn on. When a Narrow (high level) is selected, Q200 (N-ch) turn on and Q200 (P-ch) turn off. D201
and D203 are switched to ceramic filters when a high/low
level is selected.
Q204 turns on/off with the Wide/Narrow and the IC200
detector output level is changed to maintain a constant output level during wide or narrow signals.
When SP-MIC is attached, SSW is connected to GND at
inside of SP-MIC. For this reason, Q618 is turned off, and the
AF signal is input only to amplifier for EXT SP of IC609.
Change of INT/EXT SP refer to Fig. 4.

3-4. Audio amplifier circuit
The demodulated signal from IC200 goes through the
mute switch (Q203), IC600 (1/2) and IC606, high-pass filtered, low-pass filtered, high-pass filtered and de-emphasized by IC607.
The signal then goes through mute switch (Q605 1/2), and
an electronic volume control (IC605), and an AF switch (Q618
is on), and is routed to audio power amplifier (IC609), where it
is amplified and output to the internal speaker.
The audio mute signal (AM1) from the IC502 becomes
Low in the standby and Q612, Q613 which are power supply
circuit for IC609 turn off. Also, the audio mute signal (AM2)
becomes High to turn Q605 (1/2) off. When the audio is
output, AM1 becomes High to turn Q612, Q613 on, and voltage is supplied to power terminal VP of IC609. Also, AM2
becomes Low to turn Q605 (1/2) on.
The speaker is switched by the logic of speaker switching
terminal SSW on the universal connector. When SP-MIC is
not attached, the logic of SSW becomes High and SW (Q618)
is turned on, and the AF signal is input to both amplifiers of
IC609.
The output from IC200 enters FM IC again, then passed
through a bandpass filter. The noise component output from
IC200 is amplified by Q201 and rectified by D202 to produce
a DC voltage corresponding to the noise level. The DC voltage is sent to the analog port of the CPU (IC502). And IC200
outputs a DC voltage (RSSI) corresponding to the input of the
IF amplifier. The CPU reads the RSSI signal via pin 125.
IC502 determines whether to output sounds from the
speaker by comparing the input voltage of pin 124 and pin
125 with the preset value.

CIRCUIT DESCRIPTION
The output signal from the summing amplifier goes to the
VCO modulation input. The other output signal from the
summing amplifier passes through the D/A converter (IC605)
again for the BAL adjustment, and the buffer amplifier
(IC602), and goes to the TCXO modulation input.
4. Transmitter System
4-1. Microphone amplifier
The signal from the internal microphone goes through the
mute switch (Q614).
When the SP-MIC is not attached, the microphone switching terminal (MSW) on the universal connector becomes
High, and mute switch (Q614) is turned on. When the SPMIC is attached, MSW is connected to GND at inside of SPMIC. For this reason, Q614 is turned off, the internal microphone is muted, and only the input of the external microphone is supplied to the microphone amplifier.
The signal from microphone goes through D/A converter
(IC605), mute switch (Q610), and amplified by IC608 (1/2) and
limited by AGC circuit composed of D601, D602, Q606 and
Q607. IC607 is composed of high-pass filter, low-pass filter
and pre-emphasis/IDC circuit.
The signal passes through the D/A converter (IC605) for
the maximum deviation adjustment, and enters the summing
amplifier consisting of IC600 (2/2), and is mixed with the low
speed data from the CPU (IC502).
4-2. VOX
The IC608 (2/2) amplify the audio signal captured in the
microphone, and then the signal is converted into the DC
voltage D603 rectifies.
The DC voltage activates the CPU (IC502), and the VOX
starts.
4-3. Drive and Final amplifier
The signal from the T/R switch (D100 is on) is amplified by
drive amplifier (Q101 and Q102) to +15~17dBm.
The output of the drive amplifier is amplified by the RF
power amplifier (Q105) to 5.0W (1W when the power is low).
The RF power amplifier is MOS FET. The output of the RF
power amplifier is then passed through the harmonic filter
(LPF) and antenna switch (D106, D107 are on) and applied to
the antenna terminal.

The APC circuit always monitors the current flowing
through the RF power amplifier (Q105) and keeps a constant
current. The voltage drop at R125, R127 and R130 is caused
by the current flowing through the RF power amplifier and
this voltage is applied to the differential amplifier (IC100 1/2).
IC100 (2/2) compares the output voltage of IC100 (1/2)
with the reference voltage from IC502, and the output of
IC100 (2/2) controls the VGG of Q101, Q102 and Q105 to
make the both voltages to same voltage.
The change of power high/low is carried out by the change
of the reference voltage. Q106, Q107 and Q108 are turned
on and Q104 is turned off in transmit and the APC circuit is
active.

CIRCUIT DESCRIPTION
5. Frequency Synthesizer Unit
6. Control Circuit
5-1. Frequency synthesizer
The control circuit consists of microprocessor (IC502) and
its peripheral circuits. It controls the TX-RX unit and transfers
data to the Display unit. IC502 mainly performs the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading system, zone, frequency, and program data from
the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off by the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit by decode data input.
6) Transmitting tone and encode data.
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL IC (IC1) and buffer amplifiers.
The TCXO generates 16.8MHz. The frequency stability is
2.5ppm within the temperature range of –30 to +60°C. The
frequency tuning and modulation of the TCXO are done to
apply a voltage to pin 1 of the TCXO. The output of the TCXO
is applied to pin 8 of the PLL IC.
The VCO consists of 2VCO and covers a dual range of the
195.85~233.85MHz and the 136~174MHz. The VCO generates 195.85~233.85MHz for providing to the first local signal
in receive. The operating frequency is generated by Q7 in
transmit mode and Q6 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator (IC1) to the variable capacitor diodes (D5, D7, D10 and D11 in transmit mode and D9
and D13 in receive mode).
The T/R pin of IC502 goes “high” in receive mode causing
Q8 and Q7 to turn off, and Q6 turn on. The T/R pin goes
“low” in transmit mode.
The outputs from Q6 and Q7 are amplified by buffer amplifier (Q10) and doubled by Q2 and then sent to PLL IC.
The PLL IC consists of a prescaler, reference divider,
phase comparator, charge pump (The frequency step of the
PLL circuit is 10 or 12.5kHz). The input signal from the pins 8
and 5 of the PLL IC is divided down to the 10 or 12.5kHz and
compared at phase comparator. The pulsed output signal of
the phase comparator is applied to the charge pump and
transformed into DC signal in the loop filter (LPF). The DC
signal is applied to the CV of the VCO and locked to keep the
VCO frequency constant.
PLL data is output from DT (pin 112), PCK (pin 82) and PLE
(pin 81) of the microprocessor (IC502). The data are input to
the PLL IC when the channel is changed or when transmission is changed to reception and vice versa. A PLL lock condition is always monitored by the pin 80 (UL) of the microprocessor. When the PLL is unlocked, the UL goes low.

■ Flash memory
Note : The flash memory stores the data that is written by
the FPU (KPG-92D), and firmware program (User mode, Test
mode, Tuning mode, etc.). This data must be rewritten when
replacing the flash memory.
■ EEPROM
Note : The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.
■ Real-time clock
The clock function is based on real-time clock IC (IC503).
When the power supply is off, it is backed up by an internal

Memory circuit consists of the CPU (IC502) and a flash
memory (IC500). A flash memory has a capacity of 4M bits
and contains the transceiver control program for the CPU. It
also stores the data for transceiver channels and operating
parameter that are written by the FPU. This program can be
easily written from an external devices.
The EEPROM (IC504) stores the last channel data, the
scan on status, and other parameters.

CIRCUIT DESCRIPTION
6-2. Low battery warning
■ High-speed data (5-tone, DTMF)
The battery voltage is monitored by the microprocessor
(IC502 pin 126 : BATTLVL). When the battery voltage falls
below the voltage set by the Low Battery Warning adjustment during the transmission, the red LED blinks to notify the
operator that it is time to replace the battery (When the “On
TX” option (default setting) under the Battery Warning / status function in the FPU is selected.). If the battery voltage
falls below 5.8V, the transceiver does not transmit and the
warning tone beeps while the PTT switch is pressed.
High-speed data (HSD) is output from pin 7 of the CPU.
The signal passes through a low-pass CR filter and provides a
TX HSD tone and a RX HSD tone. TX HSD deviation making
an adjustment by microprocessor is passed through the
switch (IC606) and then applied to the audio processor
(IC607).
The signal is mixed with the audio signal and goes to the
VCO and TCXO. The RX HSD tone is passed a summing amplifier (IC607). The D/A converter (IC605) for audio control,
audio power amplifier and then to the speaker.

■ MSK
MSK signal is output from pin 6 of IC607. The signal
passes through the D/A converter (IC605) for the MSK deviation adjustment, and is routed to the VCO. When encoding
MSK, the microphone input signal is muted.

CIRCUIT DESCRIPTION
■ High-speed data (5-tone)
7-2. Decode
■ Low-speed data (QT, DQT)
The demodulated signal from the IF IC (IC200) is amplified
by IC600 (1/2) and passes through an audio processor (IC607)
and amplifier IC604 (1/2) and comparator IC604 (2/2) to remove a low-speed data. The CPU digitizes this signal and
decodes the signal.
The demodulated signal from the IF IC (IC200) is amplified
by IC600 (1/2) and passes through a low-pass filter (IC607) to
remove audio components. The signal is input to pin 128 of
the CPU.
The CPU digitizes this signal, performs processing such as
DC restoration, and decodes the signal.
■ MSK
The MSK input signal from the IF IC is amplified by IC600
(1/ 2) and goes to pin 5 of IC607. The signal is demodulated
by MSK demodulator in IC607. The demodulated data goes
to the CPU for processing.
■ High-speed data (DTMF)
The DTMF input signal from the IF IC (IC200) is amplified
by IC600 (1/2) and goes to IC607, the DTMF decoder. The
decoded information is then processed by the CPU. During
transmission and standby, the DTMF IC is set to the power
down mode.

Battery +B is supplied via a 2.5A fuse from the battery
terminal connected to the TX-RX unit. Power supply (+B) is
applied to the four AVRs. IC402 supplies 5V (5M) to the control circuit. IC401 and IC403 supplies 5V to common circuits.
IC406 supplies to the TX circuit, the RX circuit and common
circuits. During transmission, 5TC becomes Low and Q406
is turned on to supply 5V (5T) to the TX circuit. During reception, 5RC becomes Low and Q405 is turned on to supply 5V
(5R) to the RX circuit.
The power supply voltage monitor IC (IC400) monitors
power supply voltage (+B). If the voltage falls (less than
5.6V), the VOUT port goes “LOW” level, the CPU INT port
also goes “HIGH” level, and the CPU stops.

■ Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.

■ Universal connector
Use the interface cable (KPG-36) for PC tuning or the lead
wire with plug (E30-3287-18) and screw (N08-0535-08) for
panel tuning. Connect the plug to the universal connector of
the radio and tighten the screw.
The lead wire with plug (E30-3287-18) and screw (N080535-08) terminals are as follows. Numbers are universal
connector terminal numbers.
Caution
1. When connecting the plug to the universal connector of
the radio, a short circuit may occur. To prevent this, be
sure to turn the radio POWER switch off.
2. Since the RX AF output is a BTL output, there is a DC component. Isolate this with a capacitor or transformer as
shown in the figure.
3. Do not connect an instrument between red or black and
GND.
