CIRCUIT DESCRIPTION
1) Receiver System
The receiver system is a double superheterodyne system with a 21.7MHz first IF and
a 450kHz second IF.
1.Front End
The received signal at frequency in the 136~173.995MHz (E version:
144~145.995MHz) range is passed through the low-pass filter (L101, L102,
L104, L118, C101, 108, C109, C110, C117, C118, C119, C123, C124, C125,
C126, C127, and C188) and tuning circuit (C255, C256, C257, C258, D120,
L138, and L139) and amplified by the RF amplifier (Q119). The signal from
Q119 is then passed through the tuning circuit (C242, C243, C244, C245,
C269, C270, C271, D117, D118, D119, L135, L136, and L137) and converted
into 21.7MHz by the mixer (Q118).
The tuning circuit, which consists of L139, L135, L136, varicaps D117, D118,
D119, and D120 is controlled by the tracking voltage from the CPU so that it is
optimized for the reception frequency. The local signal from the VCO is
passed through the buffer (Q115), and supplied to the source of the mixer
(Q118). The radio uses the lower side of the superheterodyne system.
2. IF Circuit
The mixer mixes the received signal with the local signal to obtain the sum of
and difference between them. The crystal filter (FL101, and FL102) selects
21.7MHz frequency from the results and eliminates the signal of the unwanted
frequencies. The first IF amplifier (Q121) then amplifies the signal of the
selected frequency.
3. Demodulator Circuit
After the signal is amplified by the first IF amplifier (Q121), it is input to pin 16
of the demodulator IC (IC103). The second local signal of 21.25MHz (shared
with PLL IC reference oscillation), which is oscillated by the TCXO (X102).
Then, these two signals are mixed by the internal mixer in IC103 and the result
is converted into the second IF signal with a frequency of 450kHz. The second
IF signal is output from pin 3 of IC103 to the ceramic filter (FL103), where the
unwanted frequency band of that signal is eliminated, and the resulting signal
is sent back to the IC103 through pin 5.
The second IF signal input via pin 5 is demodulated by the internal limiter
amplifier and quadrature detection circuit in IC103, and output as an audio
signal through pin 9.

4. Audio Circuit
The audio signal from pin 9 of IC103 is amplified by the AF amplifier (Q120).
The signal is then input to pin 16 of the electronic volume (IC105) for volume
adjustment, and output from pin 14. The adjusted signal is sent to the audio
power amplifier (IC104) through pin 2 to drive the speaker.
5. Squelch Circuit
The signal except for the noise component in AF signal of IC103 is cut by the
active filter inside IC. The noise component is amplified and rectified, then
converted to the DC voltage to output from pin 14 of IC103. The voltage is led
to pin 2 of CPU and compared with the setting voltage. The squelch will open if
the input voltage is lower than the setting voltage.
2) Transmitter System
1. Modulator Circuit
The audio signal is converted to an electric signal in either the internal or
external microphone, and input to the microphone amplifier (IC110). IC110
consists of two operational amplifiers; one amplifier (pins 12, 13, and 14) is
composed of pre-emphasis and IDC circuits and the other (pins 5, 6, 7, 8, 9,
and 10) is composed of a splatter filter. The maximum frequency deviation is
obtained by IC105 and input to the cathode of the varicap of the VCO, to
change the electric capacity in the oscillation circuit. This produces the
frequency modulation.
2. Power Amplifier Circuit
The transmitted signal is oscillated by the VCO, amplified by the pre-drive
amplifier (Q101) and drive amplifier (Q106), and input to the final amplifier
(Q105). The signal is then amplified by the final amplifier (Q105) and led to the
antenna switch (D101) and low-pass filter (L104, L102, L101, C119, C118,
C117, C127, C126, C125, C124, C108, and C101), where un-wanted high
harmonic waves are reduced as needed, and the resulting signal is supplied to
the antenna.
3. APC Circuit
Part of the transmission power from the low-pass filter is detected by D108,
converted to DC, and then amplified by a amplifier (IC101). The output voltage
controls the bias voltage from the source of Q105 and Q106 to maintain the
transmission power constant.

3) PLL Synthesizer System
1. PLL
The dividing ratio is obtained by sending data from the CPU (IC113) to pin 10
and sending clock pulse to pin 9 of the PLL IC ( IC101 ). The oscillated signal
from the VCO is amplified by the buffer (Q116) and input to pin 8 of IC102.
Each programmable divider in IC102 divides the frequency of the input signal
by N according to the frequency data, to generate a comparison frequency of
5 or 6.25kHz.
2. Reference Frequency Circuit
The reference frequency appropriate for the channel steps is obtained by
dividing the 21.25MHz reference oscillation (X102) by 4250 or 3400,
according to the data from the CPU (IC113). When the resulting frequency is
5kHz, channel steps of 5, 10, 15, 20, and 30kHz are used. When it is 6.25kHz,
channel steps of 12.5, 25 , and 50kHz are used.
3. Phase Comparator Circuit
The PLL (IC102) uses the reference frequency, 5 or 6.25kHz. The phase
comparator in the IC102 compares the phase of the frequency from the VCO
with that of the comparison frequency, 5 or 6.25kHz, which is obtained by the
internal divider in IC102.
4. PLL Loop Filter Circuit
If a phase difference is found in the phase comparison between the reference
frequency and VCO output frequency, the charge pump output (pin 5) of IC102
generates a pulse signal, which is converted to DC voltage by the PLL loop
filter and input to the varicap of the VCO unit for oscillation frequency control.
5. VCO Circuit
A Colpitts oscillation circuit driven by Q108 directly oscillates the desires
frequency. The frequency control voltage determined in the CPU (IC113) and
PLL circuit is input to the varicaps (D105 and D107). This change the
oscillation frequency, which is amplified by the VCO buffer (Q113) and output
from the VCO unit.

4) CPU and Peripheral Circuits
1. LCD Display Circuit
The CPU turns ON the LCD via segment and common terminals with 1/4 the
duty and 1/3 the bias, at the frame frequency is 112.5Hz.
2. Display Lamp Circuit
When the LAMP key is pressed, “L” is output form pin 67 of CPU ( IC113) to
the bases of Q140. Q140 then turn ON and the LEDs (D128 and D129) light.
3. Reset and Backup
When the power form the DC jack or external battery increases from Circuits
0V to 2.5 or more, “ H “ level reset signal is output form the reset IC (IC108) to
pin 6 of the CPU (IC113), causing the CPU to reset. The reset signal, however,
waits at 100, and does not enter the CPU until the CPU clock (X104) has
stabilized.
4. S (Signal) Meter Circuit
The DC potential of pin 12 of IC103 is input to pin 83 of the CPU (IC113),
converted from an analog to a digital signal, and displayed as the S-meter
signal on the LCD.
5. DTMF Encoder
The CPU (IC113) is equipped with an internal DTMF encoder. The DTMF
signal is output from pin 71, through IC112 (Low-pass filter), and then through
the microphone amplifier (IC110), and is sent to the varicap of the VCO for
modulation. At the same time, the monitoring tone passes through the AF
circuit and is output form the speaker.
6. TONE Encoder
The CPU (IC113) is equipped with an internal tone encoder. The tone signal
(67.0 to 250.3Hz ) is output from pin 70 of the CPU to the 21.25MHz reference
oscillation (X102) of the PLL reference oscillator.
7. DCS Encoder
The CPU (IC113) is equipped with an internal DCS code encoder. The code
(023 to 754) is output from pin 70 of the CPU to the 21.25MHz reference
oscillation (X102) of the PLL reference oscillator.

8. CTCSS, DCS Decoder
The voice band of the AF output signal from pin 9 of IC103 is cut by sharp
active filter IC111 and amplified, then led to pin 80 of CPU. The input signal is
compared with the programmed tone frequency code in the CPU. The squelch
will open when they match.
9. Clock Shift
In the unlikely event that CPU clock noise is present on a particular operating
frequency programmed into the radio, you can shift the CPU clock frequency
to avoid the CPU clock-noise. The output signal from pin 8 of the CPU turns
on Q127. Then the oscillation frequency of X104 will be shifted about 200
ppm.
