REALIGNMENT
5.PC Mode
5-1. Preface
The TK-2140 transceiver is programmed by using a personal
computer, programming interface (KPG-36) and programming
software (KPG-74D).
The programming software can be used with an IBM PC or
compatible. Figure 1 shows the setup of an IBM PC for
programming.
5-2. Connection procedure
1. Connect the TK-2140 to the personal computer with the
interface cable.
2. When the POWER switch on, user mode can be entered
immediately. When PC sends command the radio enter PC
mode, and “PROGRAM” is displayed on the LCD.
When data transmitting from transceiver, the red LED is
blinking.
When data receiving to transceiver, the green LED is blinking.
Notes:
• The data stored in the personal computer must match model
type, when it is written into the flash memory.
• Change the TK-2140 to PC mode, then attach the interface
cable.
5-3. KPG-36 description
(PC programming interface cable: Option)
The KPG-36 is required to interface the TK-2140 to the
computer. It has a circuit in its D-subconnector (25-pin) case
that converts the RS-232C logic level to the TTL level.
The KPG-36 connects the universal connector of the TK-
2140 to the computers RS-232C serial port.
5-4. Programming software description
The KPG-74D programming disk is supplied in 3-1/2” disk
format. The software on this disk allows a user to program TK-
2140 radios via programming interface cable (KPG-36).
5-5. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC with
the KPG-74D, the destination data (basic radio information)
for each set can be modified. Normally, it is not necessary to
modify the destination data because their values are
determined automatically when the frequency range (frequency
type) is set.
The values should be modified only if necessary. Data can
be programmed into the flash memory in RS-232C format via
the universal connector.

1. Overview
This transceiver is VHF/FM portable transceiver designed
to operate in the frequency range of 136 to 174MHz (K) and a
VHF/FM band EFJ LTRTM trunked system compatible FM
protable transceiver that can be programmed to operate on
both LTR and conventional systems.
2. Circuit Configuration by Frequency
The receiver is a double-conversion superheterodyne with
a first intermediate frequency (IF) of 44.85MHz and a second
IF of 455kHz. Incoming signals from the antenna are mixed
with the local signal from the PLL to produce the first IF of
44.85MHz.
This is then mixed with the 44.395MHz second local
oscillator output to produce the 455kHz second IF. This is
detected to give the demodulated signal.
The transmit signal frequency is generated by the PLL VCO,
and modulated by the signal from the microphone. It is then
amplified and sent to the antenna.

3. Receiver System
3-1. RF unit
An incoming RF signal from the antenna terminal is passed
through the antenna switch (D102,103,104 and D105 are off)
and then the bandpass filter (L215,217). The bandpass filter is
adjusted by a variable capacitor. The input voltage to the
variable capacitor is regulated by the voltage output from the
D/A converter (IC307). The signal is amplified by RF amplifier
(Q207), and passed through the bandpass filter (L210,213).
The resulting signal is applied to the first mixer (Q206), where
it is mixed with the first local oscillator signal output from the
frequency synthesizer to produce the first IF (44.85MHz).
3-2. IF unit
The first IF signal is passed through a four-pole monolithic
crystal filter (XF202) to remove a adjacent channel signal. The
filtered first IF signal is amplified by the first IF amplifier (Q205)
and then applied to the lF system IC (IC200). The IF system
IC provides a second mixer, second local oscillator, limiting
amplifier, quadrature detector and RSSI (Received Signal
Strength Indicator). The second mixer mixes the first IF signal
with the 44.395MHz of second local oscillator output (crystal
unit X200) and produces the second IF signal of 455kHz.
The second IF signal is passed through the ceramic filter
(CF200; Wide, CF201 ; Narrow) to more remove the adjacent
channel signal. The filtered second IF signal is amplified by
the limiting amplifier and demodulated by the quadrature
detector with ceramic discriminator (CD200). The demodulated

3-3. Wide/Narrow changeover circuit
Narrow and Wide settings can be made for each channel
by switching the ceramic filters CF200 (Wide), CF201 (Narrow).
The WIDE (high level) and NARROW (low level) data is
output from IC311.
Regardless of NARROW or WIDE band selection, signals
always pass through the filter, CF200.
When the WIDE band is selected, Q201 is turned ON, then
D202 and D203 are turned OFF.
So, the signal does not pass through the filter CF201. When
the NARROW band is selected, Q201 is turned OFF, then D202
and D203 are turned ON. So, the signal passes through the
filters, CF200 and CF201.
Q503 turns on/off with the Wide/Narrow data and the IC200
detector output level is changed to maintain a constant output
level during wide or narrow signals.

3-4. Audio amplifier circuit
The demodulated signal from IC200 goes through the mute
switch(Q204)andisamplifiedbyIC300(2/2),high-pass filtered,
low-pass filtered, high-pass filtered, band-eliminate filtered, and
de-emphasized by IC500.
The signal then goes through an AF amplifier IC305 (2/2),
an electronic volume control (IC307), and an AF switch (Q308
is on), and is routed to audio power amplifier (IC313), where it
is amplified and output to the internal speaker.
The audio mute signal (AM1) from the shift register becomes
Low in the standby and Q302, Q303 which are power supply
circuit for IC313 turn off. Also, IC500 is set to the power down
mode according to data from microprocessor, and the AF signal
is muted. When the audio is output, AM1 becomes High to
turn Q302, Q303 ON, and voltage is supplied to power terminal
VP of IC313. Also, IC500 is canceled out of the power down
mode.
The speaker is switched by the logic of speaker switching
terminal SSW on the universal connector. When SP-MIC is
not attached, the logic of SSW becomes High and SW (Q308)
is turned ON, and the AF signal is input to both amplifiers of
IC313.
When SP-MIC is attached, SSW is connected to GND at
inside of SP-MIC. For this reason, Q308 is turned OFF, and
the AF signal is input only to amplifier for EXT SP of IC313.

4. Transmitter System
4-1. Microphone amplifier
The signal from the internal microphone goes through the
mute switch (Q301).
When the SP-MIC is not attached, the microphone switching
terminal (MSW) on the universal connector becomes High, and
mute switch (Q301) is turned ON. When the SP-MIC is
attached, MSW is connected to GND at inside of SP-MIC. For
this reason, Q301 is turned OFF, the internal microphone is
muted, and only the input of the external microphone is supplied
to the microphone amplifier.
The signal from microphone passes through the limitter
circuit in D501 and amplified by IC501 (1/2), and Mic mute
switch (Q502 is off in TX) and through the high-pass filter, the
ALC circuit, the low-pass filter, the high-pass filter, and pre-
emphasis/IDC circuit in IC500 on the small board. When
encoding DTMF, mute switch (Q501) is turned OFF for muting
the microphone input signal.
The signal passes through the D/A converter (IC307) for
the maximum deviation adjustment, and enters the summing
amplifier consisting of IC305 (1/2), and is mixed with the low
speed data from the CPU (IC309).
3-5. Squelch circuit
The output from IC200 enters FM IC again, then passed
through a band-pass filter. And passed through a band-pass
filter IC202 (2/2). The noise component output from IC202 (2/
2) is amplified by Q208 and rectified by D201 to produce a DC
voltage corresponding to the noise level. The DC voltage is
sent to the analog port of the CPU (IC309). And IC200 outputs
a DC voltage (RSSI) corresponding to the input of the IF
amplifier. The CPU reads the RSSI signal via pin 93.
IC309 determines whether to output sounds from the
speaker by comparing the input voltage of pin 91 and pin 93
with the preset value.
The output signal from the summing amplifier passes
through the D/A converter (IC307) again and goes to the VCO
modulation input.
The other output signal from the summing amplifier passes
through the D/A converter (IC307) again for the BAL
adjustment, and the buffer amplifier (IC302 : 2/2), and goes to
the VCXO modulation input.

4-2. Drive and Final amplifier
The signal from the T/R switch (D101 is on) is amplified by
drive amplifier (Q100 and Q101) to +15~17dBm.
The output of the drive amplifier is amplified by the RF power
amplifier (Q106) to 5.0W (1W when the power is low). The RF
power amplifier is MOS FET transistor. The output of the RF
power amplifier is then passed through the harmonic filter (LPF)
and antenna switch (D102,103 are on) and applied to the
antenna terminal.

4-3. APC circuit
The APC circuit always monitors the current flowing through
the drive amplifier (Q103) and the RF power amplifier (Q106)
and keeps a constant current. The voltage drop at R119, R120
and R125 is caused by the current flowing through the RF
power amplifier and this voltage is applied to the differential
amplifier (IC100 1/2).
IC100(2/2) compares the output voltage of IC100(1/2) with
the reference voltage from IC307, and the output of IC100(2/2)
controls the VGG of the RF power amplifier to make the both
voltages to same voltage.
The change of power high/low is carried out by the change
of the reference voltage. Q105,107 and 108 are turned on in
transmit and the APC circuit is active.

5. Frequency Synthesizer Unit
5-1. Frequency synthesizer
The frequency synthesizer consists of the VCXO (X1), VCO,
PLL IC(IC1) and buffer amplifiers.
The VCXO generates 16.8MHz. The frequency stability is
2.5ppm within the temperature range of -30 to +60˚C. The
frequency tuning and modulation of the VCXO are done to
apply a voltage to pin 1 of the VCXO. The output of the VCXO
is applied to pin 8 of the PLL IC.
The TK-2140’s VCO consists of 2VCO and covers a dual
range of the 180.85~218.85MHz and the 136~174MHz. The
VCO generates 180.85~218.85MHz for providing to the first
local signal in receive. The operating frequency is generated
by Q3 in transmit mode and Q2 in receive mode. The oscillator
frequency is controlled by applying the VCO control voltage,
obtained from the phase comparator (IC1) to the variable
capacitor diodes (D1, D3, D7, and D8 in transmit mode and
D2, D4, D9 and D10 in receive mode).
The T/R pin of IC312 goes “high” in receive mode causing
Q4, Q6 and Q3 to turn off, and Q2 turn on. The T/R pin goes
“low” in transmit mode.
The outputs from Q2 and Q3 are amplified by buffer amplifier
(Q5) come to the amplifiers.
The PLL IC consists of a prescaler, fractional divider,
reference divider, phase comparator, charge pump. This PLL
IC is fractional-N type synthesizer and performs in the 40, 50
or 60kHz reference signal which is eighth of the channel step
(5, 6.25 or 7.5kHz). The input signal from the pins 5 and 8 of
the PLL IC is divided down to the 40, 50 or 60kHz and compared
at phase comparator. The pulsed output signal of the phase
comparator is applied to the charge pump and transformed
into DC signal in the loop filter (LPF). The DC signal is applied
to the pin 1 of the VCO and locked to keep the VCO frequency
constant.
PLL data is output from DP (pin 73). CP (pin 74) and EP
(pin 72) of the microprocessor (IC309). The data are input to
the PLL IC when the channel is changed or when transmission
is changed to reception and vice versa. A PLL lock condition is
always monitored by the pin 30 (UL) of the microprocessor.
When the PLL is unlocked, the UL goes low.

6. Control Circuit
The control circuit consists of microprocessor (IC309) and
its peripheral circuits. It controls the TX-RX unit and transfers
data to and from the display unit. IC309 mainly performs the
following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading system, group, frequency, and program data
from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off by the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit by decode data input.
6) Transmitting tone and encode data.
6-1. Memory circuit
Memory circuit consists of the CPU (IC309) and a flash
memory (IC308), a flash memory has a capacity of 2M bits
that contains the transceiver control program for the CPU and
data such as transceiver channels and operating features.
This program can be easily written from an external devices.
Data. such as operating status, are programmed into the
EEPROM (IC310).
●Flash Memory
Note : The flash memory holds data such as written with the
FPU (KPG-74D), firmware program (User mode, Test mode,
Tuning mode, etc.) This data must be rewritten when replacing
the flash memory.
●EEPROM
Note : The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.

●Low-speed data (QT,DQT,LTR)
The demodulated signal from the IF IC (IC200) is amplified
by IC300 (2/2) and passes through a low-pass filter (IC306) to
remove audio components. The signal is input to pin 95 of the
CPU.
The CPU digitizes this signal, performs processing such as
DC restoration, and decodes the signal.
●High-speed data (DTMF)
The DTMF input signal from the IF IC (IC200) is amplified
by IC300 (2/2) and goes to IC301, the DTMF decoder. The
decoded information is then processed by the CPU. During
transmission and standby, the DTMF IC is set to the power
down mode when the PD terminal is High. When the line is
busy, the PD terminal becomes Low, the power down mode is
canceled and decoding is carried out.
●High-speed data (2 tone)
The demodulated signal from the IF IC (IC200) is amplified
by IC300 (2/2) and passes through an audio processor (IC500)
and band-pass filter IC303 (1/2) and IC 201 (1/2) to remove a
low-speed data. The CPU digitizes this signal, performs
processing such as DC restoration, and decodes the signal.
●MSK (ESN)
The MSK input signal from the IF IC is amplified by IC300
(1/ 2) and goes to pin 5 of IC500. The signal is demodulated
by MSK demodulator in IC500. The demodulated data goes to
the CPU for processing.
7. Signalling Circuit
7-1. Encode
●Low-speed data (QT,DQT,LTR)
Low-speed data is output from pin 1 of the CPU. The signal
passes through a low-pass CR filter, and goes to the summing
amplifier (IC305 1/2). The signal is mixed with the audio signal
and goes to the VCO and VCXO (X1) modulation input after
passing through the D/A converter (IC307) for BAL adjustment.
●High-speed data (DTMF)
High-speed data is output from pin 2 of the CPU. The signal
passes through a low-pass filter consisting of IC304, and
provides a TX DTMF tone and a RX DTMF tone. TX DTMF
deviation making an adjustment by microprocessor is passed
through the D/A convertor (IC307) and then applied to the audio
processor (IC500).
The signal is mixed with the audio signal and goes to the
VCO and VCXO. The RX DTMF tone is passed a summing
amplifier (IC305 2/2). The D/A converter (IC307) for audio
control, audio power amplifier and then to the speaker.
●MSK (ESN)
ESN utilizes 1200bps MSK signal. MSK signal is output from
pin 6 of IC500. The signal passes through the D/A converter
(IC307) for the MSK deviation adjustment. and is routed to the
VCO. When encoding MSK, the microphone input signal is
muted.

CIRCUIT DESCRIPTION
8. Power Supply Circuit
Battery +B is supplied via a 3A fuse from the battery terminal
connected to the TX-RX unit. After passing through the power
switch, power supply (SB) is applied to the three AVRs. IC401
supplies 5V (5M) to the control circuit, and IC403 supplies 5V
(5C) to common circuits. IC402 supplies to the TX circuit, the
RX circuit and common circuits of needless save mode. During
transmission, 5TC becomes Low and Q405 is turned ON to
supply 5V (5T) to the TX circuit. During reception, 5RC
becomes Low and Q404 is turned ON to supply 5V (5R) to the
RX Circuit.
ThepowersupplyvoltagemonitorIC(IC404)monitorspower
supply voltage (SB). If the voltage falls (less than 5V), the VOUT
port goes “LOW” level, the CPU INT port also goes “LOW”
level, and the CPU stops.
