4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT (RF UNIT)
The RF signals from the antenna connector pass through
the limitter (D68) and an attenuator (D69). The signals are
then applied to the RF circuit the antenna switching circuit
(D13, D73, D75) which suppress out-of-band signals.
4-1-2 RF CIRCUIT (RF UNIT)
The RF circuit amplifies the received signals within the
range of frequency coverage and filters out-of-band signals.
(1) 0.495 MHz–29.999 MHz
RF signals (0.495–29.999MHz) from an antenna switching
circuit (D73) pass through a low-pass filter (C511–C515,
L81, L82). The filtered signals are amplified at an RF ampli-
fier (Q505) passing through each band-pass filter depending
on the receiving frequency. The amplified signals are then
applied to the 1st mixer circuit (IC1) after being amplified at
another RF amplifier (IC11) via the band switching
diode(D71).
The signals below 1.9 MHz pass through a low-pass filter
(C534, C535, C657, C658, L88, L89) via the band switching
diode (D66), and are then applied to the RF amplifier circuit
(Q505) via the band switching diode (D67).
The 1.9 MHz–14.995 MHz signals pass through the band
switching diode (D65) and band-pass filter (C522–C531,
L85–L87, L91), and are then applied to the RF amplifier cir-
cuit (Q505) via the band switching diode (D70).
The 15 MHz–29.995 MHz signals pass through the band
switching diode (D63) and high-pass filter (C516–C520,
L83, L84) and are then applied to the RF amplifier circuit
(Q505) via the band switching diode (D64).
(2) 118 MHz–174.995 MHz, 330 MHz–832.995 MHz
RF signals (118 MHz–174.995 MHz, 330 MHz–832.995
MHz) from an antenna switching diode (D75) are passed
through each bandpass filter and RF amplifier, and are then
applied to the 1st mixer circuit (IC1) via the band switching
diode (D71) and RF amplifier (IC11).
The 118 MHz–174.995 MHz signals pass through the band
switching diode (D74) and low-pass filter (C8–C13, C67,
C416, L14, L57–L59, L70), and are then amplified at RF
amplifier (Q14). The amplified signal passes through the
tunable band-pass filters (D1, D2) and band switching diode
(D25).
The 330 MHz–469.995 MHz signals are amplified at RF
amplifier (Q35) via the band switching diode (D3) and band-
pass filter (C19–C23, C216, L2–L5). The amplified signal
passes through the tunable band-pass filters (D3, D4) and
band switching diode (D29).
The 470 MHz–832.995 MHz signals are amplified at RF
amplifier (Q24) via the band-pass filter (C32, C33,
C35–C37, C39, C144, C145), between the band switching
diode (D11, D32).
(3) 30–117.995 MHz, 175–329.995 MHz
The 30 MHz–117.95 MHz, 175 MHz–329.995 MHz signals
pass through the low-pass filter (C40–C43, C665, C666, L9,
L10, L92), and are then applied to the RF amplifier (Q36).
The amplified signals are amplified at the RF amplifier (IC11)
via band switching diodes (D34, D71). The amplified signals
are applied to the 1st mixer circuit (IC1).
(4) 833 MHz–1309.995 MHz
The 833 MHz–1309.995 MHz signals pass through the
bandpass filter (C5, C45–51, L11–L13, L43), and are then
applied to the RF amplifier (Q26). The amplified signals are
amplified at the RF amplifier (IC11) via band switching
diodes (D36). The amplified signals are applied to 1st mixer
circuit (IC1).
4-1-3 1ST MIXER CIRCUIT (RF UNIT)
The 1st mixer circuit converts the received RF signals to a
fixed frequency of the 1st IF signal with a PLL output fre-
quency. By changing the PLL frequency, only the desired
frequency will pass through the bandpass filters at the next
stage of the 1st mixer.
The filtered RF signals are mixed with 1st LO signals at the
1st mixer circuit (IC1) to produce a 266.7 MHz 1st IF signal.
The 1st IF signal is output from pin 6, and passed through
the bandpass filter (FI1) to suppress unwanted harmonic
components. The filtered 1st IF signal is applied to the 2nd
mixer circuit.
The 1st LO signals are generated at the 1st VCO (Q28, Q30,
D45) and are applied to the 1st mixer (IC1, pin 3) directly or
passing through the doubler circuit (Q31) after being ampli-
fied at the buffer amplifiers (IC4, Q40).
4-1-4 1ST IF AND 2ND MIXER CIRCUITS (RF UNIT)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal.
The filtered 266.7 MHz 1st IF signal from the bandpass filter
is mixed with the 2nd LO signal at the 2nd mixer circuit
(IC10, pin 1) to produce a 19.65 MHz 2nd IF signal. The 2nd
IF signal pass through (except WFM mode) or bypass (WFM
mode) the bandpass filter (FI3), and is then amplified at the
2nd IF amplifier (Q5). The amplified signal is applied to the
demodulator circuit.
4-1-5 DEMODULATOR CIRCUITS (RF UNIT)
The demodulator circuit converts the 2nd IF signal into AF
signals.
The 19.65 MHz 2nd IF signal from the 2nd IF amplifier (Q5)
is applied to the 3rd mixer section of the FM IF IC (IC2, pin
16) and is then mixed with the 3rd LO signal for conversion
into a 450 kHz 3rd IF signal.

4 - 2
IC2 contains the 3rd mixer, limiter amplifier, quadrature
detector and S-meter detector, etc. A frequency from the
PLL reference oscillator is used for the 3rd LO signal (19.20
MHz).
(1) FM mode
The 3rd IF signal is output from FM IF IC (IC2, pin 3) and
passes through the ceramic bandpass filter (FI2). The fil-
tered signal is fed back and amplified at the limiter amplifier
section (pin 5), then demodulated AF signals at the quadra-
ture detector section (pins 10, 11) and detector coil (L21).
The demodulated AF signals are output from pin 9 and are
applied to the AF circuit (LOGIC unit).
(2) WFM mode
The 3rd IF signal from the 3rd mixer bypasses the ceramic
filter (FI2) and fed back to the limiter amplifier section (pin 5).
The amplified signal is demodulated at the quadrature
detector section (pins 10, 11) and detector coil (L21). TheAF
signals are output from pin 9 and are applied to the AF cir-
cuit (LOGIC unit).
By connecting R55 to R54 in parallel, the output character-
istics of pin 12, “RSSI”, change gradually. Therefore, the FM
IF IC can detect WFM components.
(3) AM mode
The filtered 3rd IF signal from the bandpass filter (FI2) is
amplified at the 3rd IF amplifier (Q1). The amplified IF signal
is applied to the AM detector circuit (Q4) to converted into
AF signals, and the signals are applied to the AF circuit
(LOGIC unit).
4-1-6 AF AMPLIFIER CIRCUIT (LOGIC UNIT)
The AF amplifier circuit amplifies the demodulated AF sig-
nals to drive a speaker.
While in FM mode, AF signals from the demodulator circuit
(RF unit) are passed through the de-emphasis circuit (R118,
C66, C68) with frequency characteristics of –6 dB/octave,
and are then applied to the pre-amplifier (Q31) via the band-
pass filter (Q30).
While in AM mode, AF signals are pass through the band-
pass filter and are then applied to the pre-amplifier (Q31).
While in WFM mode, AF signals are applied to the pre-
amplifier (Q31) directly.
The pre-amplified AF signals pass through the AF mute cir-
cuit (Q37) and are then applied to the electronic volume con-
trol circuit (IC14, pin 6). The level controlled AF signals are
output from pin 7 and applied to the AF power amplifier
(IC15, pin 1) via the buffer amplifier (Q36). The power ampli-
fied AF signals are applied to the internal speaker via the
[EXT SP] jack.
The electronic volume control circuit controlsAF gain, there-
fore, the AF output level is according to the [VOL] setting
and also the squelch conditions.
4-1-7 SQUELCH CIRCUIT (LOGIC AND RF UNITS)
• NOISE SQUELCH
The noise squelch circuit cuts out AF signals when no RF
signals are received. By detecting noise components in the
AF signals, the squelch circuit switches the AF mute switch.
A portion of the AF signals from the FM IF IC (RF unit; IC2,
pin 9) are applied to the active filter section (IC2, pin 8). The
active filter section amplifies and filters noise components.
The filtered signals are applied to the noise detector section
and output from IC2 (pin 13) as the “SDET” signal.
The “SDET” signal from IC2 (pin 13) passes through the
noise detector (LOGIC unit; IC1), and is then applied to the
CPU (LOGIC unit; IC11, pin 12) via the “SQL” line. The CPU
analyzes the noise condition and outputs the “AMUTE” sig-
nal to the AF mute switch (Q37).
Even when the squelch id closed, the AF mute switch (Q37)
opens at the moment of emitting beep tones.

• TONE SQUELCH
The tone squelch circuit detects AF signals and opens the
squelch only when receiving a signal containing a matching
subaudible tone (CTCSS). When tone squelch is in use, and
a signal with a mismatched or no subaudible tone is
received, the tone squelch circuit mutes the AF signals even
when noise squelch is open.
A portion of the AF signals from the FM IF IC (IC2, pin 9)
passes through the low-pass filter (LOGIC unit; IC9) via the
“WFMS” line to remove AF (voice) signals and is applied to
the CTCSS decoder inside the CPU (LOGIC unit; IC11, pin
8) via the “RTONE” line to control the AF mute switch.
4-2 PLL CIRCUITS
4-2-1 PLL CIRCUIT (RF UNIT)
A PLL circuit provides stable oscillation of the receive
1st/2nd LO frequencies. The PLL circuit compares the
phase of the divided VCO frequency to the reference fre-
quency. The PLL output frequency is controlled by the divid-
ed ratio (N-data) of a programmable divider.
An oscillated signal from the 1st VCO passes thorough the
buffer amplifiers (IC4, Q43) is applied to the PLLIC (IC3, pin
19) and is prescaled in the PLL IC based on the divided ratio
(N-data). The PLLIC detects the out-of-step phase using the
reference frequency and outputs it from pin 13. The output
signal is passed through the loop filter (Q2, Q45) and is then
applied to the 1ST VCO circuit as the lock voltage.
4-2-2 REFERENCE OSCILLATOR CIRCUIT
(RF UNIT)
The reference oscillator circuit (X1, IC3) generates a 19.2
MHz reference frequency which is stabilized within the tem-
perature range –10˚C (+14˚F) to +60˚C (+140˚F). The refer-
ence frequency is applied to the PLL IC (IC3, pin 16) and the
signal is output from the pin 17, and is then applied to the
FM IF IC (IC2, pin 2) via the low-pass fileter.
4-2-3 1ST VCO CIRCUIT (RF UNIT)
The oscillated signal is applied to the buffer amplifiers (IC4,
Q40). The amplified signal is applied to the 1st mixer circuit
(IC1) via the RX LO swtich circuit (D42–D44) and doubler
circuit (Q31).
The 1st VCO circuit (Q28, Q30, D54) oscillates 267.2
MHz–380 MHz and 380 MHz–550 MHz by switching the
SHIFT switch (Q29) “High” and “Low” respectively.
A portion of the signal from IC4 is amplified at the buffer
amplifier (Q43) and is then fed back to the PLL IC (IC3, pin
2) as the comparison signal.
4-2-4 2nd VCO CIRCUIT (RF UNIT)
The 2nd LO circuit generates the 2nd LO frequencies, and
the signals are applied to the 2nd mixer circuit.
The 2nd VCO circuit (Q6, L45, C80, C207, C208) oscillates
260 MHz. The oscillated signal is applied to the 2nd mixer
(IC10, pin 3), and is then mixed with the 1st IF signal.
An oscillated signal from the 2nd VCO passes through the
low-pass filter (C154, C250–C252, L69), and is applied to
the PLL IC (IC3, pin 2), and is then output from pin 8.

5-1 PREPARATION
The receiver (IC-R2) must be adjusted on the adjustment mode after programmed adjustment frequency data into memory chan-
nel. When you program adjustment frequency data into memory channel, optional CS-R2 PROGRAMMING SOFTWARE, OPC-478
CLONING CABLE are requird.
‘‘REQUIRED TEST EQUIPMENT
‘‘SOFTWARE INSTALLATION
NOTE: Before using the program, make a backup copy of the original disk. After making a backup copy, keep the original disk
in a safe place.
qBoot up DOS.
wInsert the backup disk into the floppy drive A.
eType the following to install the adjustment program:
A:\>INSTALL A C:\CSR2 [Enter]
‘‘ADJUSTMENT FREQUENCY DATA
When program adjustment frequency data (at right) into memory
channel, back up the original memory data using the optional CS-
R2, OPC-478, and re-program it after adjustment.
CAUTION: When clone the adjustment frequency data to the
receiver, the receiver’s memory channel wiil be over-
written the data and deleted original memory data at
same time.
‘‘ENTERING THE ADJUSTMENT MODE
qConnect a JIG (see illustration at CONNECTION) to the [SP]
jack.
wPush and hold [FUNC], then turn power ON.
eDisconnect the JIG and connect a PC with an OPC-478.
rBoot up DOS.
tType the following to start up the adjustment program:

• Main menu appears at the top side of the cloning program,
select the sub-menu “Screen”–“Memory CH”–“Bank 1”, then
input adjustment frequency (at right).
ySelect “Write –> Receiver” of the Clone on the top menu.
• Application writes adjustment frequency data to the connected receiver.
uDisconnect the cloning cable and turn power OFF, then turn power ON to start adjustment.
‘‘OPERATING ON THE ADJUSTMENT MODE
Change the value : [DIAL]
Change the channel [UP] : [BAND]
Change the channel [DOWN] : [BAND]
‘‘EXITING THE ADJUSTMENT MODE
When the adjustment is finished, the receiver must be cancelled adjustment mode to use normal operation, otherwise receiver
does not work properly.
qTurn power OFF.
wPush and hold [FUNC] and [V/M], then turn power ON.
