• KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-3107 with the
computer. It has a circuit in its D-subconnector (25-pin) case
that converts the RS-232C Iogic level to the TTL Ievel. The
KPG-22 connects the side panel jacks of the TK-3107 to the
computer's RS-232C serial port.
• Programming software description
The KPG-55D Programming Disk is supplied in 3-1/2" the disk
format. The Software on this disk allows a user to program the
TK-3107 radios via a Programming interface cable (KPG-22).
• Programming with IBM PC
If data is transferred to the transceiver from an IBM PC with
the KPG-55D, 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 EEPROM in RS-232C
format via the SP MIC plug.
In this mode the PTT Iine operates as TXD and RXD data lines
respectively.

2.Receiver
The receiver is double conversion superheterodyne,
designed to operate in the frequency range of 470 to 490MHz.
The frequency configuration is shown in Fig. 1.
1) Front - end RF amplifier
An incoming signal from the antenna is applied to an RF
amplifier (Q203) after passing through a transmit/receive
switch circuit (D102 and D103 are off) and a 3-pole LC filter.
After the signal is amplified (Q203), the signal is filtered by a
band pass filter (a 3-pole LC filter) to eliminate unwanted
signals before it is passed to the first mixer.
The voltage of these diodes are controlled by to track the MPU
(IC403) center frequency of the band pass filter. (See Fig. 2)

XF201:L71-0522-05
CF200:L72-0958-05
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 (Q202) to create a 38.85MHz first
intermediate frequency (1st IF) signal. The first IF signal is
then fed through two monolithic crystal filters (MCFs : XF201)
to further remove spurious signals.
3) IF amplifier
The first IF signal is amplified by Q201, and then enters
IC200 (FM processing IC). The signal is heterodyned again
with a second local oscillator signal within IC200 to create a
450kHz second IF signal. The second IF signal is then fed
through a 450kHz ceramic filter (CF200) to further eliminate
unwanted signals before it is amplified and FM detected in
IC200.
4) AF amplifier
The recovered AF signal obtained from IC200 is amplified
by IC300 (1/4), filtered by the IC300 low-pass filter (2/4) and
IC300 high-pass filter (3/4) and (4/4), and de-emphasized by
R303 and C306. The AF signal is then passed through a
WIDE/NARROW switch (Q303). The processed AF signal
passes through an AF volume control and is amplified to a
sufficient level to drive a loud speaker by an AF power
amplifier (IC302).

2) VCO
The operating frequency is generated by Q4 in transmit
mode and Q3 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained from
the phase comparator, to the varactor diodes (D2 and D4 in
transmit mode and D1 and D3 in receive mode). The T/R pin is
set high in receive mode causing Q5 and Q7 to turn Q4 off,
and turn Q3 on . The T/R pin is set low in transmit mode. The
outputs from Q3 and Q4 are amplified by Q6 and sent to the
buffer amplifiers.
5) Squelch
Part of the AF signal from the IC enters the FM IC 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
microprocessor (IC403). IC403 determines whether to output
sounds from the speaker by checking whether the input
voltage is higher or lower than the preset value.
To output sounds from the speaker, IC403 sends a high signal
to the MUTE and AFCO Iines and turns IC302 on through
Q302, Q304, Q305, Q306 and Q307.(See Fig. 3)
3.PLL frequency synthesizer
The PLL circuit generates the first local oscillator signal for
reception and the RF signal for transmission.
1) PLL
The frequency step of the PLL circuit is 5 or 6.25kHz.
A 12.8MHz reference oscillator signal is divided at IC1 by a fixed
counter to produce the 5 or 6.25kHz reference frequency. The
voltage controlled oscillator (VCO) output signal is buffer
amplified by Q6, then divided in IC1 by a dual-module
programmable counter . The divided signal is compared in phase
with the 5 or 6.25kHz reference signal in the phase comparator in
IC1. The output signal from the phase comparator is filtrered
through a low-pass filter and passed to the VCO to control the
oscillator frequency. (See Fig.4)

6) Receive signaling
QT/DQT
300 Hz and higher audio frequencies of the output signal
from IF IC are cut by a low-pass filter (IC301). The resulting
signal enters the microprocessor (IC403). IC403 determines
whether the QT or DQT matches the preset value, and
controls the MUTE and AFCO and the speaker output sounds
according to the squelch results.

4. Transmitter
1) Transmit audio
The modulation signal from the microphone is amplified by
IC500 (1/2), passes through a preemphasis circuit, and
amplified by the other IC500 (1/2) to perform IDC operation.
The signal then passes through a low-pass filter (splatter fiIter)
(Q501 and Q502) and cuts 3kHz and higher frequencies. The
resulting signal goes to the VCO through the VCO modulation
terminal for direct FM modulation. (See Fig. 6)
2) QT/DQT encoder
A necessary signal for QT/DQT encoding is generated by
IC403 and FM-modulated to the PLL reference signal. Since
the reference OSC does not modulate the loop characteristic
frequency or higher, modulation is performed at the VCO side
by adjusting the balance. (See Fig. 6)

3) VCO and RF amplifier
The transmit signal obtained from the VCO buffer amplifier
Q100, is amplified by Q101 and Q102. This amplified signal is
passed to the power amplifier, Q105 and Q107, which
consists of a 2-stage FET amplifier and is capable of
producing up to 4W of RF power. (See Fig.7)
4) ANTswitchandLPF
The RF amplifier output signal is passed through a low-
pass filter network and a transmit/receive switching circuit
before it is passed to the antenna terminal. The transmit/
receive switching circuit is comprised of D101, D102 and
D103. D102 and D103 are turned on (conductive) in transmit
mode and off (isolated) in receive mode.

5) APC
The automatic power control (APC) circuit stabilizes the
transmitter output power at a predetermined level by sensing
the drain current of the final amplifier Field Effect Transistor
(FET) . The voltage comparator, IC100 (2/2), compares the
voltage obtained from the above drain current with a reference
voltage which is set using the microprocessor. An APC
voltage proportional to the difference between the sensed
voltage and the reference voltage appears at the output of
IC100 (1/2). This output voltage controls the gate of the FET
power amplifier, which keeps the transmitter output power
constant. The transmitter output power can be varied by the
microprocessor which in turn changes the reference voltage
and hence, the output power.
6) Terminal protection circuit
When the thermistor (TH102) reaches about 80˚C, the
protection circuit turns on Q110 to protect transmitting final
amplifier (Q107) from the over heating.
5. Power supply
A 5V reference power supply [5M] for the control circuit is
derived from an internal battery. This reference is used to
provide a 5V supply in transmit mode [5T], a 5V supply in
receive mode [5R], and a 5V supply common in both modes
[5C] based on the control signal sent from the microprocessor.
6. Control system
The IC403 CPU operates at 7.37MHz . This oscillator has a
circuit that shifts the frequency according to the EEPROM
data.
3) UNLOCK DETECTOR
If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from D7, R6,
and C1 causes the voltage applied to the UL pin of the
microprocessor to go low. When the microprocessor detects
this condition, the transmitter is disabled, ignoring the push-to-
talk switch input signal. ( See Fig.5)
