Frequency Configuration
The receiver utilizes double conversion. The first IF is
49.95MHz and the second IF is 450kHz. The first local oscil-
lator signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary
frequencies. Figure 1 shows the frequencies.
CIRCUIT DESCRIPTION
Receiver System
The receiver is double conversion superheterodyne. The
frequency configuration is shown in Figure 1.
■Front-end RF Amplifier
An incoming signal from the antenna is applied to an RF
amplifier (Q353) after passing through a transmit/receive
switch circuit (D603, D604 and D605 are off) and a BPF
(L359, L358 L360, L361 and varactor diodes : D353, D354,
D355). After the signal is amplified (Q353), the signal is fil-
tered by a BPF (L354, L355 and varactor diodes: D351, D352)
to eliminate unwanted signals before it is passed to the first
mixer.
The voltage of these diodes are controlled by tracking the
CPU (IC101) center frequency of the band pass filter. (See
Fig. 2.)
■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 (Q352) to create a 49.95MHz first
intermediate frequency (1st IF) signal. The first IF signal is
then fed through one pair of monolithic crystal filter (MCF :
XF351) to further remove spurious signals.

■IF Amplifier
The first IF signal is amplified by Q351, and then goes to
IC301 (FM processing IC). The signal is heterodyned again
with a second local oscillator signal within IC301 to create a
450kHz second IF signal. The second IF signal is then fed
through a 450kHz ceramic filter (Wide : CF301, Narrow :
CF302) to further eliminate unwanted signals before it is am-
plified and FM detected in IC301.

■Wide/Narrow Switching Circuit
The Wide port (pin 65) and Narrow port (pin 64) of the CPU
is used to switch between ceramic filters. When the Wide
port is high, the ceramic filter SW diodes (D303, D302) cause
CF301 to turn on to receive a Wide signal.
When the Narrow port is high, the ceramic filter SW diodes
(D303, D302) cause CF302 to turn on to receive a Narrow sig-
nal. (See Fig. 3.)
■AF Signal System
The detection signal from IF IC (IC301) goes to D/A con-
verter (IC161) to adjust the gain and is output to AF filter
(IC251) for characterizing the signal. The AF signal output
from IC251 and the DTMF signal, BEEP signal are summed
and the resulting signal goes to the D/A converter (IC161).
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 (IC252). The AF signal from IC252 switches
between the internal speaker and speaker jack (J1) output.
(See Fig. 4.)
■Squelch Circuit
The detection output from the FM IF IC (IC301) passes
through a noise amplifier (Q301) to detect noise. A voltage is
applied to the CPU (IC101). The CPU controls squelch ac-
cording to the voltage (SQIN) level. The signal from the RSSI
pin of IC301 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
16.8MHz reference oscillator signal is divided at IC401 by a
fixed counter to produce the 5 or 6.25kHz reference fre-
quency. The voltage controlled oscillator (VCO) output signal
is buffer amplified by Q410, then divided in IC401 by a dual-
module programmable counter. The divided signal is com-
pared in phase with the 5 or 6.25kHz reference signal in the
phase comparator in IC401. 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 Q406 in trans-
mit mode and Q405 in receive mode. The oscillator fre-
quency is controlled by applying the VCO control voltage,
obtained from the phase comparator, to the varactor diodes
(D405 and D406 in transmit mode and D403 and D404 in
receive mode). The TX/RX pin is set high in receive mode
causing Q408 and Q407 to turn Q406 off, and turn Q405 on.
The TX/RX pin is set low in transmit mode. The outputs
from Q405 and Q406 are amplified by Q410 and sent to the
RF amplifiers. (See Fig. 6.)

■Unlock Circuit
During reception, the 8RC signal goes high, the 8TC signal
goes low, and Q34 turns on. Q33 turns on and a voltage is
applied to 8R. During transmission, the 8RC signal goes low,
the 8TC signal goes high and Q36 turns on. Q35 turns on and
a voltage is applied to 8T.
The CPU monitors the PLL (IC401) LD signal directly.
When the PLL is unlocked during transmission, the PLL LD
signal goes low. The CPU detects this signal and makes the
8TC signal low. When the 8TC signal goes low, no voltage is
applied to 8T, and no signal is transmitted. (See Fig. 7.)

Transmitter System
■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 (D409) and ampli-
fied by Q500, Q501, Q502 and Q503. The amplified signal
goes to the final amplifier (Q504) through a low-pass filter.
The low-pass filter removes unwanted high-frequency har-
monic 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 (Q504) output with a diode
(D606, D607) and applies a voltage to IC501. IC501 com-
pares the APC control voltage (PC) generated by the D/A con-
verter (IC161) and DC amplifier (IC203) with the detection
output voltage. IC501 generates the voltage to control Q502,
Q503 and Q504 and stabilizes transmission output.
The APC circuit is configured to protect over current of
Q502, Q503 and Q504 due to fluctuations of the load at the
antenna end and to stabilize transmission output at voltage
and temperature variations. (See Fig. 9.)

Control Circuit
The CPU carries out the following tasks (See Fig. 10.):
1) Controls the WIDE, NARROW, TX/RX outputs.
2) Adjusts the AF signal level of the AF filter (IC251) and
turns the filter select compounder on or off.
3) Controls the display unit.
4) Controls the PLL (IC401).
5) Controls the D/A converter (IC161) and adjusts the vol-
ume, modulation and transmission power.
■Memory Circuit
The transceiver has an 64k-bit EEPROM (IC66). The
EEPROM contains adjustment data. The CPU (IC101) con-
trols the EEPROM through three serial data lines. (See Fig.
11.)

■Display Circuit
The CPU (IC101) controls the display LCD and LEDs.
When power is on, the LCD driver will use the BL line to con-
trol the LCD illumination and key backlight LEDs.
The brightness function is controlled by the switch Q12.
The LCD driver (IC3) and CPU (IC101) communicate through
the CE, CL, DI, DO lines. (See Fig. 12.)
■Key Matrix Circuit
The AR-440 front panel has function keys. Each of them
is connected to a cross point of a matrix of the KI1 to KI3 and
KS1 to KS2 ports of the LCD driver.
The LCD driver monitors the status of the KI1 to KI3 and
KS1 to KS2 ports. If the state of one of the ports changes,
the LCD driver assumes that the key at the matrix point corre-
sponding to that port has been pressed.
■Encode
The DCS and CTCSS signals are output from QT/DQT of
the CPU (IC101) and summed with the external pin DI line by
the summing amplifier (IC203) and the resulting signal goes
to the D/A converter (IC161). The DTMF signal is output from
DTMF pin of the CPU and summed with a MIC signal by the
summing amplifier (IC203), and the resulting signal goes to
the D/A converter (IC161).
The D/A converter (IC161) adjusts the MOD level and the
balance between the MOD and CTCSS/DCS levels. Part of a
CTCSS/DCS signal is summed with MOD and the resulting
signal goes to the VCOMOD pin of the VCO. This signal is
applied to a varicap diode in the VCO for direct FM modula-
tion.

■Decode
• CTCSS/DCS
The signal (W/NO (EVOL2)) goes to DTMF IN (pin 95) of
CPU (IC101). The CTCSS/DCS signal will pass through the
low-pass filters in the CPU (IC101) and be decoded within the
CPU (IC101). The DTMF signal will be decoded within the
CPU (IC101).
■D/A Converter
The D/A converter (IC161) is used to adjust MO modula-
tion, AF volume, TV voltage, FC reference voltage, and PC
POWER CONTROL voltage level.
Adjustment values are sent from the CPU as serial data.
The D/A converter has a resolution of 256 and the following
relationship is valid:
D/A output = (Vin – VDAref) / 256 x n + VDAref
Vin: Analog input
VDAref: D/A reference voltage
n: Serial data value from the microprocessor (CPU)
Power Supply Circuit
When the power switch on the display unit is pressed, the
power port on the display unit which is connected port 17
(POWER), goes low, then port 82 (SBC) goes high, Q32 turns
on, SB SW (Q31) turns on and power (SB) is supplied to the
radio.
When the DC power supplied to the radio, the voltage
regulator IC (IC33) supply into the CPU VDD and reset voltage
detect IC (IC34). IC34 will generate signal (RESET) in to the
reset terminal on the CPU (IC101) to carry out a power ON
reset. If DC power is less than about 9.5V, the radio is unable
to power on.
When the DC power voltage deceases from normal volt-
age, the INT voltage detector IC (IC35) will set to high on CPU
port 18 (INT) if B line will became less than about 9.5V. Then
CPU send to EEPROM (IC66) the backup data and go into
STOP mode.
This circuit has an overvoltage protection circuit. If a DC
voltage of 18V or higher is applied to the base of Q61, this
voltage turns Q61 on and will set to high on CPU port 18
(INT). Then CPU send to EEPROM (IC66) the backup data
and go into stop mode. (See Fig. 16.)

CIRCUIT DESCRIPTION
Data Terminal and Peripheral Circuits
CN2 (data terminal) is the data communications terminal
on the TX/RX PCB. It handles transmission control, data in-
put/output, and squelch signals.
There are two data communications modes : 9600bps
mode and 1200bps mode. Unlike with 1200bps AFSK, with
this type of high-speed modulation, frequency modulation is
carried out after the digital base band signals (rectangular
wave) are passed through a band limiting filter. For 9600bps
GMSK for example, compared to 4800Hz signals (nearly sine
wave signals passed through a filter), these signals have a
hissing sound like digital modulation when listened to by ear.
Different types of modulation, such as GMSK is distin-
guished by the type of band limiting filter.

■Transmission Signals
Transmission modulation signals enter from PKD of the
data terminal (CN2). The path to the modulation depends on
whether communications are 1200bps or 9600bps mode.
For 1200bps mode, the transmission modulation signals
from single analog switch (IC204) pass through MIC amplifier
(IC201,202) and summing amplifier (IC203), and go to VCO
(X401) through D/A converter (IC161).
For 9600bps mode, the transmission modulation signals
from single analog switch (IC205) pass through summing
amplifier (IC303), go to TCXO (X401) and VCO through D/A
converter (IC161). (See Fig. 17.)
■Reception Signals
PR9 is the 9600bps data communications reception out-
put. It outputs the FM detection circuit output through an AF
filter (IC251). These signals are always output whether the
squelch is open or closed.
PR1 is the 1200bps data communications reception out-
put. It outputs the FM detection circuit output through an AF
filter (IC251). Output is controlled with the mute switch
(Q252) according to whether squelch is open or closed. (See
Fig. 17.)
■Squelch Signal Output Circuit
The squelch circuits is input to the TNC to prevents con-
flicts from occurring between simultaneous receive mode
and transmit mode traffic during packet communications
(only during 1200bps). The signal is output from pin 29 of
IC101 to the data terminal. The logic is as shown in the table
below.

Resetting the Tansceiver
If your transceiver seems to be malfunctioning, resetting
the microprocessor may solve the problem. The following 2
reset modes are available. When performing the reset, you
may lose memory data and stored information. Back up or
write down important data before performing the reset.
■Initial Settings
The factory defaults for the operating frequencies are as
follows.
Transceiver : 410.000MHz (C), 450.000MHz (C2)
The Memory Channels have no data stored. The Call
Channel and frequency step size default values.
Note : When in Channel Display Mode or while Key Lock is
activated, you cannot perform VFO reset or Full reset.
■Full Reset
This resets all transceiver parameters to the factory de-
fault values. There are two methods available for resetting
the transceiver.
• Full Reset Method 1:
1. With the transceiver power OFF, press [F]+[ ] (Power).
• All indicators light momentarily, followed by the full reset
confirmation message.
■VFO Reset
This resets the transceiver parameters excluding the
DTMF Memory, the Memory channel contents, and the Call
channel contents. There are two methods available for reset-
ting the transceiver.
Note : Menu No. 7 (P.VFO) and Menu No. 10 (OFFSET) re-
turn to the factory default values.
• VFO Reset Method 1:
1. With the transceiver power OFF, press [VFO]+[ ]
(Power).
• The VFO reset confirmation message appears.
2. Press [F].
• “SURE ?” appears.
• Press any key other than [F] to cancel.
3. Press [F] again to reset the transceiver.
• “WAIT” appears momentarily.
• Full Reset Method 2:
1. Press [F], [MENU] and turn the Tuning control to select
Menu No. 99 (RESET).
2. Press [MENU] and turn the Tuning control to select
“FULL”.
3. Press [MENU].
• “SURE ?” appears.
• Press any key other than [MENU] to cancel.
4. Press [MENU] to reset the transceiver.
• “WAIT” appears momentarily.
2. Press [VFO].
• “SURE ?” appears.
• Press any key other than [VFO] to cancel.
3. Press [VFO] again to reset the transceiver.
• “WAIT” appears momentarily.
• VFO Reset Method 2:
1. Press [F], [MENU] and turn the Tuning control to select
Menu No. 99 (RESET).
2. Press [MENU] and turn the Tuning control to select
“VFO”.
3. Press [MENU].

1. Frequency Tune
2. Transmit High Power *2
3. Transmit Low Power *2
4. DCS Balance *3
5. Max Deviation *3
6. CTCSS Fine Deviation *3
qBlinks in Adjustment Mode.
wAdjustment item display
eAdjustment value display. Can be adjusted while it is
“blinking”.
Displayed as a hexadecimal number from 00 to FF.
rAdjustment value stored in memory.
When an adjustment value is determined, it is equal to the
value in “3”.
■
Panel Key Operation Method in Adjustment Mode
qPower switch/Volume control
wWhen the knob is pressed once, the adjustment value dis-
play blinks. (Select an adjustment item with “4” or “5”
key before performing the operation. It cannot be per-
formed while transmitting.)
When the knob is rotated while the adjustment display is
blinking, the adjustment value changes. (Adjust transmis-
sion items while transmitting.)
When the knob is pressed again, the adjustment value
stops blinking and lights, and the adjustment value is
saved in the memory of the transceiver. (For transmission
item adjustment, enter receive mode before performing
the operation.)
eChanging between adjustment value display and fre-
quency display
The display changes as follows : Adjustment value display
→Transmit frequency display →Receive frequency dis-
play →Adjustment value display.
The frequency for adjustment can be confirmed.
rMoves the adjustment item backward. (If it is operated
when a frequency is displayed, the adjustment item dis-
play returns.)
tMoves the adjustment item forward. (If it is operated
when a frequency is displayed, the adjustment item dis-
play returns.)
yIf it is pressed before determining the adjustment value,
the adjustment value of the Adjustment item returns to its
original value.
uNot used in Adjustment Mode.
Note :
If Max Power for transmission is low, check the DC cable.
If the DC cable connector has poor contact due to rust or
stain, voltage may drop occur frequently and correct trans-
mission power may not be supplied.
In this case, polish the DC cable connector. If the problem
still persists, replace the DC cable with a new one.
