CIRCUIT DESCRIPTION
1) Receiver System DR-135
The receiver system is a double super-heterodyne system with a 21.7MHz first IF and a 450kHz
second IF.
1. Front End
2. IF Circuit
3. Demodulation Circuit
The received signal at any frequency in the 136.000MHz to 173.995MHz
range is passed through the low-pass filter (L116, L115, L114, L113, C204,
C203, C202, C216 and C215) and tuning circuit (L105, L104 and D105,
D104), and amplified by the RF amplifier (Q107). The signal from Q107 is
then passed through the tuning circuit (L103, L102, and variable capacitor
D103, D102) and converted into21.7MHz by the mixer (Q106). The tuning
circuit, which consists of L105, L104, variable capacitor D105 and D104,
L103, L102, variable capacitor D103 and D102, is controlled by the
tracking voltage from the VCO. The local signal from the VCO is passed
through the buffer (Q145), and supplied to the source of the mixer (Q106).
The radio uses the lower side of the super-heterodyne system.
The mixer mixes the received signal with the local signal to obtain the sum
of and difference between them. The crystal filter (XF102, XF101) selects
217 MHz frequency from the results and eliminates the signal of the
unwanted frequencies. The first IF amplifier (Q105) then amplifies the
signal of the selected frequency.
After the signal is amplified by the first IF amplifier (Q105), it is input to
pin 16 of the demodulator IC (IC108). The second local signal of21.25MHz
(shared with PLL IC reference oscillation), which is oscillated the external
oscillator X102 (VCTCXO), is input through pin 1 of IC108. Then, these
two signals are mixed by the internal mixer in IC108 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 IC108 to the ceramic filter (FL102
or FL101), where the unwanted frequency band of that signal is
eliminated, and the resulting signal is sent back to the IC108 through pin
5. The second IF signal input via pin 5 is demodulated by the internal
limiter amplifier and quadrature detection circuit in IC 108, and output as
an audio signal through pin 9.
4. Audio Circuit
The audio signal from pin 9 of IC 108 is amplified by the audio amplifier
(IC120:A), and switched by the signal switch IC (IC111) and then input it to
the de-emphasis circuit.
And is compensated to the audio frequency characteristics in the
de-emphasis circuit (R203, R207, R213, R209, C191, C218, C217) and
amplified by the AF amplifier (IC120:B). The signal is then input to volume
(VR1). The adjusted signal is sent to the audio power amplifier (1C117)
through the pin 1 to drive the speaker.
3
5. Squelch Circuit
The detected output which is outputted from pin 9 of IC108 is inputted to
pin 8 of IC108 after it was been amplified IC120:Aand it is outputted from
pin 7 after the noise component was been, eliminated from the composed
band pass filter in the built in amplifier of the IC, then the signal is rectified
by the internal diode in IC108 to convert into DC component. The adjusted
voltage level at VR101 is delivered to the comparator of the CPU.
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.
During open squelch, pin 30 (SQC) of the CPU becomes “L" level, AF
control signal is begin controlled and sounds is outputted from speaker.
6. AIR Band Reception
(T version only)
When the frequency is within 118.000 - 135.995MHz, Q113 automatically
turns on, pin 5 of IC 121 becomes “H” level and the condition becomes in
AM detection mode.
The receiver signal passed through the duplexer is let to the antenna
switch (D107, D101). After passing through the band-pass filter, the signal
is amplified by RF amplifier Q112. Secondly the signal is mixed with the
signal from the first local oscillator in the first-mixer Q106, then converted
into the first IF. Its unwanted signal is let to pin 16 of IC108. Then
converted into the second IF. And is demodulated by AM decoder of Q118,
and is output from Q108 as the AF signal.
7. WIDE/NARROW
Switching circuit
The second IF 450kHz signal which passes through filter FL101 (wide)
and FL102 (narrow) during narrow, changes its width using the width
control switching D116 and D115.
2) Transmitter System DR-135
1. Modulator Circuit
The audio signal is converted to an electrical signal by the microphone,
and input it to the microphone amplifier (Q6). Amplified signal which
passes through mic-mute control IC109 is adjusted to an appropriate
mic-volume by means of mic-gain adjust VR106.
IC114:D and C consists of two operational amplifiers; one amplifier (pin
12,13 and 14) is composed of pre-emphasis and IDC circuit and the other
(pin 8, 9 and 10) is composed of a splatter filter. The maximum frequency
deviation is obtained by VR107. And input to the signal switch (IC113)
(9600 bps packet signal input switch) and input to the cathode of the
variable capacitor of the VCO, to change the electric capacity in the
oscillation circuit. This produces the frequency modulation.
2. Power Amplifier Circuit
3. APC Circuit
4
The transmitted signal is oscillated by the VCO, amplified by the younger
amplifier (Q115), and input to the final power module (IC110). The signal is
then amplified by the final power module (IC110) and led to the antenna
switch (D110) and low-pass filter (L113, L114, L115, L116, C215, C216,
C202, C203 and C204), where unwanted high harmonic waves are
reduced as needed, and the resulting signal is supplied to the antenna.
Part of the transmission power from the low-pass filter is detected by
D111, converted to DC. The detection voltage is passed through the APC
circuit (IC114:A, 1C114:B), then it controls the APC voltage supplied to
final power module IC110 to fix the transmission power.
3) PLL Synthesizer Circuit DR-135
1.PLL
The dividing ratio is obtained by sending data from CPU (IC1) to pin 10
and sending clock pulses to pin 9 of the PLL IC (IC116). The oscillated
signal from the VCO is amplified by the buffer (Q134 and Q135) and input
to pin 8 of IC116. Each programmable divider in IC116 divides the
frequency of the input signal by N according to the frequency data, to
generate a comparison frequency of 5 or 6.25 kHz.
2. Reference Frequency
Circuit
3. Phase Comparator Circuit
4. PLL Loop Filter Circuit
5. VCO Circuit
The reference frequency appropriate for the channel steps is obtained by
dividing the 21.25 MHz reference oscillation (X102) by 4250 or 3400,
according to the data from the CPU (IC1). When the resulting frequency is
5 kHz, channel step of 5, 10, 15, 20, 25, 30 and 50 kHz are used. When it
is 6.25 kHz, the 12.5 kHz channel step is used.
The PLL (IC116) uses the reference frequency, 5 or 6.25 kHz. The phase
comparator in the IC116 compares the phase of the frequency from the
VCO with that of the comparison frequency, 5 or 6.25 kHz, which is
obtained by the internal divider in IC116.
If a phase difference is found in the phase comparison between the
reference frequency and the VCO output frequency, the charge pump
output (pin 5) of IC116 generates a pulse signal, which is converted DC
voltage by the PLL loop filter and input to the input to the variable
capacitor of the VCO unit for oscillation frequency control.
A Colpitts oscillation circuit driven by Q131 directly oscillates the desired
frequency. The frequency control voltage determine in the CPU (IC1) and
PLL circuit is input to the variable capacitor (D122 and D123). This change
the oscillation frequency, which is amplified by the VCO buffer (Q134,
Q145) and output from the VCO area.
6. VCO Shift Circuit
During transmission or the AIR band Reception (118 ~ 136 MHz), the VCO
shift circuit turns ON Q138, change control the capacitance of L123 and
safely oscillates the VCO by means of H signal from pin 42 of IC1.
4) Receiver System DR- 435
The receiver system is a double super-heterodyne system with a 30.85MHz first IF and a 455kHz
second IF.
1. Front End
The received signal at any frequency in the 430.000MHz to 439.995MHz
range is passed through the low-pass filter ( L115, L114, L116, C204,
C203, C202, C216 and C215) and amplified by the RF amplifier (Q107).
The signal from Q107 is then passed through the BPF circuit (L103, L102)
and converted into 30.85MHz by the mixer (Q106). The local signal from
the VCO is passed through the buffer (Q134, Q145), and supplied to the
source of the mixer (Q106). The radio uses the lower side of the
super-heterodyne system.
5
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 (XF101) selects 30.85
MHz frequency from the results and eliminates the signal of the unwanted
frequencies. The first IF amplifier (Q105) then amplifies the signal of the
selected frequency.
3. Demodulation Circuit
4. Audio Circuit
5. Squelch Circuit
After the signal is amplified by the first IF amplifier (Q105), it is input to
pin16 of the demodulator IC (IC108). The second local signal of
30.395MHz (Crystal oscillator) is input through pin 1 of IC108. Then, these
two signals are mixed by the internal mixer in IC108 and the result is
converted into the second IF signal with a frequency of 455kHz. The
second IF signal is output from pin 3 of IC108 to the ceramic filter (FL101
or FL102), where the unwanted frequency band of that signal is
eliminated, and the resulting signal is sent back to the IC108 through pin
5.
The second IF signal input via pin 5 is demodulated by the internal limiter
amplifier and quadrature detection circuit in IC 108, and output as an
audio signal through pin 9.
The audio signal from pin 9 of IC 108 is amplified by the audio amplifier
(IC120:A), and switched by the signal switch IC (IC111) and then input it to
the de-emphasis circuit.
And is compensated to the audio frequency characteristics in the
de-emphasis circuit (R203, R207, R213, R209, C191, C218, C217) and
amplified by the AF amplifier (IC120:B). The signal is then input to volume
(VR1). The adjusted signal is sent to the audio power amplifier (IC117)
through the pin 1 to drive the speaker.
The detected output which is outputted from pin 9 of IC108 is inputted to
pin 8 of IC108 after it was been amplified !C120:A and it is outputted from
pin 7 after the noise component was been eliminated from the composed
band pass filter in the built in amplifier of the IC, then the signal is rectified
by the internal diode in IC108 to convert into DC component. The adjusted
voltage level at VR101 is delivered to the comparator of the CPU.
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.
During open squelch, pin 30 (SQC) of the CPU becomes “L” level, AF
control signal is begin controlled and sounds is outputted from speaker.
6. WIDE/NARROW
Switching circuit

The second IF 455kHz signal which passes through filter FL101 (wide)
and FL102 (narrow) during narrow, changes its width using the width
control switching D116 and D115.

The audio signal is converted to an electrical signal by the microphone,
and input it to the microphone amplifier (Q6). Amplified signal which
passes through mic-mute control IC109 is adjusted to an appropriate
mic-volume by means of mic-gain adjust VR106.
IC114:D and C consists of two operational amplifiers; one amplifier (pin
12,13 and 14) is composed of pre-emphasis and IDC circuit and the other
(pin 8, 9 and 10) is composed of a splatter filter. The maximum frequency
deviation is obtained by VR107. And input to the signal switch (IC113)
(9600 bps packet signal input switch) and input to the cathode of the
variable capacitor of the VCO, to change the electric capacity in the
oscillation circuit. This produces the frequency modulation.
The transmitted signal is oscillated by the VCO, amplified by the drive
amplifier (Q138) and younger amplifier (Q115), and input to the final
power module (IC110). The signal is then amplified by the final power
module (IC110) and led to the antenna switch (D110) and low-pass filter
(L116, L114, L115, C215, C216, C202, C203 and C204), where unwanted
high harmonic waves are reduced as needed, and the resulting signal is
supplied to the antenna.
Part of the transmission power from the low-pass filter is detected by
D111, converted to DC. The detection voltage is passed through the APC
circuit (IC114:A, IC114:B), then it controls the APC voltage supplied to the
final power module IC110 to fix the transmission power.

Circuit
3. Phase Comparator Circuit
4. PLL Loop Filter Circuit
The dividing ratio is obtained by sending data from CPU (IC1) to pin 10
and sending clock pulses to pin 9 of the PLL IC (IC116). The oscillated
signal from the VCO is amplified by the buffer (Q134 and Q135) and input
to pin 8 of IC116. Each programmable divider in IC116 divides the
frequency of the input signal by N according to the frequency data, to
generate a comparison frequency of 5 or 6.25 kHz.
The reference frequency appropriate for the channel steps is obtained by
dividing the 21.25 MHz reference oscillation (X102) by 4250 or 3400,
according to the data from the CPU (IC1). When the resulting frequency is
5 kHz, channel step of 5, 10, 15, 20, 25, 30 and 50 kHz are used. When it
is 6.25 kHz, the 12.5 kHz channel step is used.
The PLL (IC116) uses the reference frequency, 5 or 6.25 kHz. The phase
comparator in the 1C116 compares the phase of the frequency from the
VCO with that of the comparison frequency, 5 or 6.25 kHz, which is
obtained by the internal divider in IC116.
If a phase difference is found in the phase comparison between the
reference frequency and the VCO output frequency, the charge pump
output (pin 5) of IC116 generates a pulse signal, which is converted DC
voltage by the PLL loop filter and input to the input to the variable
capacitor of the VCO unit for oscillation frequency control.

Q145) and output from the VCO unit
7) CPU and Peripheral Circuits
1. LCD Display Circuit
2. Dimmer Circuit
3. Reset and Backup
4. S (Signal) Meter Circuit
5. DTMF Encoder
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 64 Hz.
The dimmer circuit makes the output of pin 13 of CPU (JC1) into “H” level
at set mode, so that Q9 and Q3 will turn ON to make the lamp control
resistor R84 short and make its illumination bright. But on the other hand,
if the dimmer circuit makes pin 13 Into “L” level, Q9 and Q3 will turn OFF,
R84's illumination will become dimmer as its hang on voltage falls down in
the working LED (D11, D2, D5, D3 and D6).
When the power from the DC cable increases from Circuits 0 V to 2.5 V or
more, “H" level reset signal is output from the reset IC (IC4) to pin 33 of
the CPU (IC1), causing the CPU to reset. The reset signal , however,
waits at 100, and dose not enter the CPU until the CPU clock (X1) has
stabilized.
The DC potential of IF IC is input to pin 1 of the CPU (IC1), converted from
an analog to a digital signal, and displayed as the S-meter signal on the
LCD.
The CPU (IC1) is equipped with an internal DTMF encoder. The DTMF
signal is output from pin 10, through R35, R34 and R261 (for level
adjustment), and then through the microphone amplifier (IC114:A), and is
sent to the variable capacitor of the VCO for modulation. At the same time,
the monitoring tone passes through the AF circuit and is output from the
speaker.
6. Tone Encoder
7. DCS Encoder
8. CTCSS, DCS Decoder
8
The CPU (IC1) is equipped with an internal tone encoder. The tone signal
(67.0 to 250.3 Hz) is output from pin 9 of CPU to the variable capacitor
(D122 and D123) of the VCO for modulation.
The CPU (IC1) is equipped with an internal DCS code encoder. The code
(023 to 754) is output from pin 9 of CPU to the volt a ge con trol pin of
VCTCXO (X102) of the PLL reference oscillator. When DCS is ON, DCS
MUTE circuit (Q126-ON, Q133-ON, Q132-OFF) works. The modulation
activates in X102 side only.
The voice band of the AF output signal from pin 1 of IC120:A is cut by
sharp active filter IC104:A, B and C (VCVS) and amplified, then led to pin
4 of CPU. The input signal is compared with the programmed tone
frequency code in the CPU. The squelch will open when they match.
During DCS, Q108 is ON, C419 is working and cut off frequency is
lowered.
8) Power Supply Circuit
When power supply is ON, there is a "L" signal being inputted to pin 39 (PSW) of CPU which enables the CPU to
work. Then, “H” signal is outputted from pin 41 (C5C) of CPU and drives ON the power supply switch control Q8
and Q7 which turns the 5VS ON. 5VS turns ON the PLL IC (1C116), main power supply switch Q127 and Q122,
AF POWER IC117 and the 8V of AVR (IC115). During reception, pin 29 (R5)of CPU outputs “H” level, Q124 is ON,
and the reception circuits supplied by 8 V. While during transmission, pin 28 (T5) of CPU outputs “L” ievei which is
reverse by Q11 so that the output in Q128 will be “H” level, Q123 is ON, and the transmission circuit is supplied by
8 V. Or, in the case when the condition of PLL is UNLOCK, “H” level is outputted from pin 14 of PLL IC, UNLOCK
switch Q129 is ON, transmission switch Q128 is OFF which makes the transmission to stop.
1. ACC External Power Supply Terminal
When optional power supply cord EDC-37 etc. is connected to the
external power supply terminal JK101, with ACC power supply ON, switch
Q101 will turn ON, 5 V of AVR IC101 pin 2 (STB) becomes “L” which
makes CSV to turn ON. With this, it can turn the power supply of the radio
ON.
