(PC programming interface cable: Option)
The KPG-22A is required to interface the transceiver with
the computer.It has a circuit in its D-sub connector (KPG-22A:
9-pin) case that converts the RS-232C logic level to the TTL
level.
The KPG-22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.
3-4. KPG-22U Description
(USB programming interface cable: Option)
The KPG-22U is a cable which connects to a USB port
on a computer.

4.Wireless Clone Mode
4-1. Outline
“Wireless Clone Mode” copies the transceiver data to an-
other transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.
4-2. Example
The transceiver can copy the programming data to one or
more transceivers via RF communication.
The clone source and clone target/s must be in wireless
clone mode.
4-3. Operation
1. To switch the clone target/s to Wireless Clone mode,
press and hold the [PTT] and [side2] keys while turning
the transceiver power ON.
2. Wait for 2 seconds. The LED will light orange and the
transceiver will announce “Clone”.
3. Select a channel table number using Side1 (increment
channel table) and Side2 (decrement channnel table)
keys.
4. To switch the clone source to wireless clone mode, press
and hold the [PTT] and [side2] keys while turning the
transceiver power ON.
5. Wait for 2 seconds. The LED will light orange and the
transceiver will announce “Clone”.
6. Select the same channel table number as the clone
target/s.
7. Press [PTT] on the clone source to begin data transmis-
sion.
When the clone target starts to receive data, the LED will
light green.
When the clone source finishes sending data, a “confir-
mation” tone will sound.
If data transmission fails while cloning, an “error” tone will
sound from the target unit.
8. If the cloning fails, no data will be available in the target
unit when it is returned to User mode.
9. When the cloning is successful, the target unit’s “Scan”
and “Key lock” functions will return to their default values
(Scan = OFF, Key lock = OFF).
Note:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers wireless clone Mode is configured as
“Disabled”, the transceiver cannot enter Clone mode.
• The table shown below will cover the frequency tables
used for wireless cloning.
• Wireless clone mode cannot be entered in battery low
state.
• A unit cannot be a “Source Unit” if it is unprogrammed. If
[PTT] is pressed, an “error” tone will sound.
• The language used in cloning depends on the “Model
type” setting, not the FPU setting.
• Once a unit is set to be the source, it cannot be a target
after the data has been transmitted. This protects the
data in the source unit.
• Electronic interface may cause a failure in data transfer
during Wireless Clone, such as when waveforms or elec-
tromagnetics are being performed at the workbench.
• Wireless clone mode can be used ONLY by the au-
thorized service personnel.
• The wireless clone mode setting must be configured
as“Disable”before being delivered to the end-user.
• To clone, replace the antenna from both the source
transceiver and the target transceiver with a dummy
load.
• The transmit output power is automatically set to
Low in clone mode.

2-1. Front End (RF Amplifier) Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D201, D202, D203
and D204) and a BPF (L415 and L416), and is then ampli-
fied by the RF amplifier (Q405).
The resulting signal passes through a BPF (L410,L411
and L413) and goes to the mixer.These BPF are adjusted by
variable capacitance diodes (D400, D401, D402, D403 and
D404).The input voltage to the variable capacitance diode is
a regulated voltage output from the DC amplifier (IC704).
2-2. First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q404 to pro-
duce a first IF frequency of 50.85MHz.
The resulting signal passes through the XF400 MCF to
cut the adjacent spurious and provide the optimum charac-
teristics, such as adjacent frequency selectivity.

CIRCUIT DESCRIPTION
2-3. IF Amplifier Circuit
The first IF signal is passed through a four-pole mono-
lithic crystal filter (XF400) to remove the adjacent channel
signal. The filtered first IF signal is amplified by the first IF
amplifier (Q403) and is then applied to the IF system IC
(IC400).
The IF system IC provides a second mixer, limiting
amplifier, quadrature detector and RSSI (Received Signal
Strength Indicator). The second mixer mixes the first IF sig-
nal with the 50.85MHz signal of the second local oscillator
output (Q403) and produces the second IF signal of 450kHz.
The second IF signal is passed through the ceramic filter
(CF401) to remove the adjacent channel signal. The filtered
second IF signal is amplified by the limiting amplifier and
demodulated by the quadrature detector with the ceramic
discriminator (CD400). The demodulated signal is routed to
the audio circuit.
2-4. Audio Amplifier Circuit
The demodulated signal from IC400 is sent to an AF am-
plifier through IC705, and is routed to an audio power ampli-
fier (INT:IC709,EXT:IC707) where it is amplified and output
to the speaker.

2-5. Squelch Circuit
Part of the AF signal from the IC400 enters the FM IC
(IC400) again, and the noise component is amplified and
rectified by a filter and an amplifier to produce a DC voltage
corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of
the MCU (IC702). IC702 determines whether or not to output
sounds from the speaker by checking if the input voltage is
higher or lower than the preset value.
To output sounds from the speaker, IC702 sends a high
signal to the AFSW line and turns IC707 on through Q709,
Q710, Q713 and Q716. This explanation is a case of exter-
nal speaker amplifier. In the case of internal loudspeaker
amplifier, IC702 sends a high signal to the AFSW line and
turns IC709 on through Q711 and Q714.
3.Transmitter System
3-1. Microphone Amplifier Circuit
The signal from the microphone is limited by the AGC
circuit, which is composed of D700, D701, Q705, Q706 and
the mute switch (Q704). IC705 is composed of a high-pass
filter, low-pass filter and pre-emphasis/IDC circuit.
The signal from the microphone and the low speed data
from the MCU (IC702) enter the baseband IC (IC705) and
pass through each path and are mixed inside the IC.
The output signal from the audio processor goes to the
VCO modulation input. The other output signal goes to the
TCXO modulation input.

3-2. Drive and Final Amplifier Circuit
The signal from the T/R switch (D15 is on) is amplified by
the pre-drive amplifier (Q201) to 20mW.
The output of the pre-drive amplifier is amplified by the
drive amplifier (Q206) and the RF final amplifier (Q208) to
5.0W (1W when the power is low).
The drive amplifier and the RF final amplifier consist of
two MOS FET stages.
The output of the RF final amplifier is then passed
through the harmonic filter (LPF) and antenna switch (D203
and D204) and is applied to the antenna terminal.
3-3. APC Circuit
The APC circuit always monitors the current flowing
through the drive amplifier (Q206) and the RF power ampli-
fier (Q208) and keeps a constant current. The voltage drop
at R230, R231 and R233 is caused by the current flowing
through the RF final amplifier. This voltage is applied to the
differential amplifier IC200 (1/2).
IC200 (2/2) compares the output voltage of IC200 (1/2)
with the reference voltage from IC705(32pin:AUXDAC1).The
output of IC200 (2/2) controls the gate bias voltage of the
RF power amplifier and the drive amplifier to make both volt-
ages the same.
The change of power high/low is carried out by the
change of the reference voltage.

CIRCUIT DESCRIPTION
4. Frequency Synthesizer Unit
4-1. Frequency synthesizer
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL-IC (IC2), and buffer amplifiers.
The TCXO generates 16.8MHz.The frequency stability is
1.5ppm within the temperature range of –30°C to +60°C.The
frequency tuning and modulation of the TCXO are done to
apply voltage to pin 1 of the TCXO.The output of the TCXO
is applied to pin 1 of PLL-IC.
The VCO consists of 2 VCOs and covers a dual range
of 399.15~469.15MHz and 450~520MHz. The VCO gener-
ates 399.15~469.15MHz for providing the first local signal
for reception. The operating frequency is generated by Q6 in
transmitting mode and Q5 in receiving mode.The oscillation
frequency is controlled by applying the VCO control voltage,
obtained from the phase comparator (IC2) to the variable
capacitance diodes (D5, D9, D11,and D13 in transmitting
mode and D4,D7 and D12 in receiving mode)
The TX/RX pin of IC702 goes “high” in transmitting mode,
causing Q8 to turn off, and Q7 turn on. The TX/RX pin goes
“low” in receiving mode.
The output from Q5 and Q6 are amplified by a buffer am-
plifier (Q9) and Q2, and then sent to the PLL-IC. The PLL-IC
consists of a prescaler, reference divider, phase comparator,
and charge pump. The input signal from pin 1 and 8 of the
PLL-IC is divided down and compared at the phase compar-
ator.The pulsed output signal of the phase comparator is ap-
plied to the charge pump and transformed into a DC signal
in the loop filter (LPF).The DC signal is applied to the CV of
the VCO and locked to keep the VCO frequency constant.
PLL data is output from PLL_LE (pin 72), PLL_DATA (pin
73) PLL_CLK (pin 74), and PLL_PS (pin 70) of the MCU
(IC702).The data is input to the PLL-IC when the channel is
changed or transmission is changed to reception and vice
versa.The PLL lock condition is always monitored by pin 71
(PLL_LD) of the MCU. When the PLL is unlocked, PLL_LD
goes low.
Fig. 5 Drive and final amplifier and APC circuit
5. Control Circuit
The control consists of the MCU (IC702) and its peripher-
al circuits. It controls the TX-RX unit. IC702 mainly performs
the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading channel information, frequency, and program
data from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off via the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit via the decode data in-
put.
6) Transmitting tone and encode data.

that shifts the frequency via Beat shift switch (Q701, Q702).
A beat sound may be able to be evaded form generation
if “Beat Shift“ is set to ON when it is generated in the internal
spurious transmission modulated sound of the transceiver.

5-2. Memory Circuit
The Memory circuit consists of the MCU (IC702) and EE-
PROM (IC700).The EEPROM has a capacity of 64k bits and
stores the channel information, the last channel data, the
scan on status, and other parameters.
■EEPROM
Note:
The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.
5-3. Low BatteryWarning
The battery voltage is monitored by the MCU (IC702 pin
63: BATT). When the battery voltage falls below the voltage
set by the Low Battery Warning adjustment, the red LED
blinks, notifying the operator that it is time to replace the bat-
tery (when the always option (default setting) under the Bat-
tery Warning function in the FPU is selected). If the battery
voltage falls bellow 5.9V, the transceiver does not transmit
and the warning tone beeps while the PTT switch is pressed.
5-4. Key Input
Keys and channel selector circuit.
The signal from the keys and channel selector are direct-
ly input to the MCU, as shown in Figure 10.

6. Signaling Circuit
6-1. Encode
■Low-speed data (QT, DQT)
Low-speed data is output from pin2 of the MCU.The sig-
nal passes through the low pass CR filter, and goes to the
audio processor (IC705). The signal is mixed with the audio
signal and goes to the VCO and TCXO (X1) modulation in-
put after passing through the D/A converter inside the audio
processor (IC705) for BAL adjustment.
■High-speed data (2-tone,DTMF)
High-speed data (HSD) is output from pin 3 of the MCU.
HSD deviation made by an adjustment in the MCU is passed
through the low pass CR filter and then applied to the base-
band IC (IC705).
The signal is mixed with the audio signal and goes to the
VCO and TCXO. The signal passes through low pass CR fil-
ter and D/A converter, and goes to the audio power amplifier.
The level is controlled by the MCU.
■MSK
The MSK signal is generated in the audio processor
(IC705).The signal passes through the D/A converter (inside
the baseband IC: IC705) and is routed to the VCO. When
encoding the MSK, the microphone input signal is muted.
6-2. Decode
■QT/DQT
The output signal from the IF IC (IC400) enters the MCU
(IC702) through IC705. IC702 determines whether or not
the QT or DQT matches the preset value, and controls the
AFSW and speaker output sounds according to the squelch
results.
■2-tone
Part of the received AF signal output from the IF IC (IC400)
passes through the baseband IC (IC705) is compared, and
then goes to MCU (IC702). IC702 checks whether or not the
2-tone data is necessary. If it matches, IC702 carries out a
specified operation, such as turning the speaker on.
■MSK (Fleet Sync)
The MSK input signal from the IF IC (IC400) goes to
IC705. The decoded information is then processed by the
MCU.
■DTMF
The DTMF input signal from the IF IC (IC400) goes to
IC705. The decoded information is then processed by the
MCU.

CIRCUIT DESCRIPTION
7. Power Supply
There are five 5V power supplies and three 3.3V power
supplies: 50M, 50V, 50C, 50R, 50T, 33M, 33MS and 33B.
50M and 33M are always output while the power is on.
33MS is always output, but turns off when the power is
turned off, to prevent malfunction of the MCU.
50C is a common 5V and is output when SAVE is not set
to ON.
50R is 5V for reception and output during reception.
50T is 5V for transmission and output during transmis-
sion.
50V is 5V for the SP/MIC connector.
33B is 3.3V for the baseband IC (IC705).
