Receiver
The receiver is double conversion super heterodyne, designed to operate in the frequency range of 400
to 490MHz.
The frequency configuration is shown in Fig. 1.
Front - end RF amplifier
An incoming signal from the antenna is applied to an RF amplifier (Q206) after passing through a
transmit/receive switch circuit (D213 are off) and a band pass filter (L207, L208, L211 and varactor diodes:
D207, D208). After the signal is amplified (Q206), the signal is filtered through a band pass filter (L205,
L206 and varactor diodes: D205, D206) to eliminate unwanted signals before it is passed to the first mixer.
The voltage of these diodes are controlled by tracking the D/A (U505) center frequency of the band
pass filter. (See Fig. 2.)

CIRCUIT DESCRIPTION
First Mixer
The signal from the RF amplifier is heterodyned with the first local oscillator signal from the PLL
frequency synthesizer circuit at the first mixer (Q205) to create a 38.850MHz first intermediate frequency
(1st IF) signal. The first IF signal is then fed through one pair of monolithic crystal filter (MCF : XF200 and
XF201) to further remove spurious signals.
IF amplifier
The first IF signal is amplified by Q204, and then goes to U200 (FM processing IC). The signal is
heterodyned again with a second local oscillator signal within U200 to create a 450kHz second IF signal.
The second IF signal is then fed through a 450kHz ceramic filter (Wide : CF201, Narrow : CF200) to
further eliminate unwanted signals before it is amplified and FM detected in U200.
Wide/Narrow Switching Circuit
The Wide port and Narrow port (pin 35) of the CPU is used to switch between ceramic filters. When the
Wide port is high, the ceramic filter SW diodes (D200, D201) cause CF201 to turn on to receive a Wide
signal.
When the Narrow port is low, the ceramic filter SW diodes (D200, D201) cause CF200 to turn on to
receive a Narrow signal. (See Fig. 3.)

AF Signal System
The detection signal from IF IC (U200) goes to D/A converter (U505) for adjusting the gain and is output
to AF filter (U502) for characterizing the signal. It is also amplified by entering compander amplifier (U500).
The AF signal output from U500 and the TONE signal are summed up and the resulting signal goes to the
D/A converter (U505). The AFO output level is adjusted by the D/A converter. The signal output from the
D/A converter is input to the audio power amplifier (U506). The AF signal from U505 was inputted into
(U506).The AF signal from (U506) switches between the internal speaker and speaker jack (J502) output.

CIRCUIT DESCRIPTION
Squelch Circuit
The detection output from the FM IF IC (U200) passes through a noise amplifier (U201 2/2) to detect
noise. A voltage is applied to the CPU (U2). The CPU controls squelch according to the voltage (SQIN)
level. The signal from the RSSI pin of U200 is used for S-meter. The electric field strength of the receive
signal can be known before the SQIN voltage is input to the CPU, and the scan stop speed is improved.

PLL frequency synthesizer
The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission.
PLL
The frequency step of the PLL circuit is 5 or 6.25kHz. A 19.200MHz reference oscillator signal is divided
at U205 by a fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled
oscillator (VCO) output signal is buffer amplified by Q211, then divided in U205 by a dualmodule
programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal in
the phase comparator in U205. The output signal from the phase comparator is filtered through a low-pass
filter and passed to the VCO to control the oscillator frequency. (See Fig. 6.)
VCO
The operating frequency is generated by Q217 in transmit mode and Q216 in receive mode. The
oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase
comparator, to the varactor diodes (D219 and D221 in transmit mode and D218 and D220 in receive
mode). The TX/RX pin is set high in receive mode causing Q201 and Q218 to turn Q217 off, and turn
Q216 on. The TX/RX pin is set low in transmit mode. The outputs from Q216 and Q217 are amplified by
Q210 and sent to the RF amplifiers. (See Fig. 6.)

The CPU in the control unit monitors the PLL (U205) LD signal directly. When the PLL is unlocked
during transmission, the PLL LD signal goes low. The CPU detects this signal and makes the TXC signal
low. When the TXC signal goes low, no voltage is applied to 8T, and no signal is transmitted. (See Fig. 7.)

Outline
The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the
carrier signal by means of a varicap diode.
Power Amplifier Circuit
The transmit output signal from the VCO passes through the transmission/reception selection diode
(D202) and amplified by Q208, Q219, Q212 and Q214. The amplified signal goes to the final amplifier
(Q215) through a low-pass filter. The low-pass filter removes unwanted high-frequency harmonic
components, and the resulting signal is transmitted through the antenna terminal. (See Fig. 8.)

APC Circuit
The automatic transmission power control (APC) circuit detects part of a final amplifier output with a
diode (D228, D229) and applies a voltage to U202. U202 compares the APC control voltage (PC)
generated by the D/A converter (U505) with the detection output voltage. U202 generates the voltage to
control Q214 and Q215 and stabilizes transmission output.
The APC circuit is configured to protect over current of Q214 and Q215 due to fluctuations of the load

Encode
DCS and CTCSS data is output through 42 PIN of CPU. The signal passes through low-pass CR filter,
and the signal attained goes into the D/A converter (U505). The high speed data of DTMF/2T/5T Tone is
output through 58 PIN of CPU, The signal passes through low-pass CR filter, providing TX and SP output
audio frequency, and has processed IDC after amplified by a U504(B/4). The signal then passes through a
low-pass filter (separation filter) U504 (C/4 and D/4), and filter the parts which are higher than 3kHz, and
the signal attained goes into the D/A converter (U505).
The D/A converter (U505) adjusts the balance between the MOD and DCS/CTCSS levels. Signal of
DCS/CTCSS port is summed with MOD and the resulting signal goes to the VCO. This signal is applied to
a varicap diode in the VCO for direct FM modulation. (See Fig. 13.)
