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.

The adjustment should be operated in the Adjustment mode. Therefore except for the reference

frequency, deviation and tone-deviation adjustments an operator won’t touch the components on

the board, but most of the adjustments should be done by operating the dial and keys on the unit.

During such operation, memory channels are used temporary therefore it is required to program

memories before the unit is set to the adjustment mod. Please refer the chart below for the
programming channels. The frequencies may be varied within the range of ±0.2Mhz depending

on the RF environment around your work area, and refer the instruction manual for how to

program the memories into the memory-channels.

To enter the adjustment mode, press “F” then “KL” to key-lock the unit. Then press the

numeric keys in order of ”4”, “9”, “0”, “2”, “1” and “7”. Observe that decimal points appear on the

display below 100MHz and 10MHz digits. To exit from the adjustment mode, repeat the whole

sequence (key-lock then enter the code in order). NEVER RESET THE UNIT WHILE

OPERATING IN THE SET MODE. This may reset whole adjustment values resulting the

malfunction of the unit in the operating mode. The chart below shows the adjustment points and

interface between the unit and instruments. Please use an attenuator in case the specifications of

the linear-detector and frequency counter may exceed the requirement herein.

* Simply memory the frequencies only into the relative memory channels.
