face Cable : Option)
The KPG-46 is required to interface the TKR-750 to the
computer. It has a circuit in its D-sub connector (25-pin) case
that converts the RS-232C logic level to the TTL level.
The KPG-46 connects the microphone connector of the
TKR-750 to the computer’s RS-232C serial port.
3-4. Programming Software Description
The KPG-91D(C) is the programming software for TKR-
750 supplied on a CD-ROM. This software runs under Win-
dows 98, ME, Windows 2000 or XP on an IBM-PC or compat-
ible machine.
The data can be input to or read from TKR-750 and edited
on the screen. The programmed or edited data can be
printed out. It is also possible to tune the transceiver.
3-5. Programming With IBM PC

4-3. Programming
1. Start up the programming software (Fpro. exe).
2. Set the communications speed (normally, 115200 bps)
and communications port in the configuration item.
3. Set the firmware to be updated by file name item.
4. Turn the TKR-750 power on with the [PF1] key held down.
Hold the key down for one second until the 7-segment
display changes to “P.G.”. When “P.G.” appears, release
your finger from the key.
5. Check the connection between the TKR-750 and the per-
sonal computer, and make sure that the TKR-750 is in the
program mode.
6. Press write button in the window. A window opens on
the display to indicate progress of writing.
7. If writing ends successfully, the TX LED on the TKR-750
lights.
8. If you want to continue programming other TKR-750s, re-
peat steps 3 to 6.
Notes :
This mode cannot entered if the firmware program mode
is set to disable in the programming software (KPG-91D(C)).
4-4. Function
If you press the [PF1] key (front panel), both decimal point
on the 7-segment display will disappear. The writing speed is
38400 bps (low-speed mode). If you press the [PF1] key
again, the right hand decimal points will light. The writing
speed is 57600 bps (middle-speed mode).

1. External Power Supply Connection
(Rear Connectors)
This unit has two external power supply connectors : Main
DC and Backup.
If an external DC power supply is connected to the main
DC connector and a backup battery is connected to the
Backup connector at the same time, the DC power supply
switches to the battery automatically if power failure occurs.
Therefore, the operation of the repeater can be continued.
If the battery is used, but both the battery and power sup-
ply need not be connected (if an external switch is used or if
only a solar battery is used), connect it to the Backup connec-
tor, not the Main DC connector. Current consumption can be
reduced by approx. 120mA because the relay is not used.
If it is installed when the temperature at the repeater site
is below freezing, check whether the switch (relay) works
properly after installation.
2. Voice Scrambler
It operates only during base operation. The voice is not
scrambled when it is repeated.
2-1. Modification
1) Remove R742 and R653 on the TX-RX unit (B/2) : control
section.
2-2. Connection
1) The functions of pins of CN601 on the TX-RX unit (B/2) :
control section are shown in the figure.
2) Join the CN601 connector to the voice scrambler board via
the E37-0808-05 connector cable.
When the operation is checked in PC test mode after the
modification, and the maximum deviation is adjusted, the
voice from the local microphone is not modulated. In this
case, remove the CN601 12-pin (PTO) cable and connect it to
the land of the display unit (X54-333) from the voice scram-
bler. The voice from the local microphone can be modulated
in PC test mode.

Notes :
1. Make this modification after removing the DC power sup-
ply and battery for safety.
2. When the DC power supply is connected after the modifi-
cation, DC voltage is output to the Backup connector. Be
careful during setup.
3. When the backup battery is used for a long time, remove
the battery from the repeater and recharge it because the
trickle charge is not sufficient for recharging a completely
discharged battery.

CIRCUIT DESCRIPTION / !
2-2. First Mixer
The signal from the BPF is heterodyned with the first local
oscillator signal from the PLL frequency synthesizer circuit at
the first mixer DBM (A1) to become a 44.85MHz first inter-
mediate frequency (IF) signal. The first IF signal is fed
through two monolithic crystal filters (XF2; Wide, XF1; Nar-
row) to further remove spurious signals.
2-3. IF Amplifier
The first IF signal is amplified by Q2 and Q3, and then en-
ters IC9 (FM system IC). The signal is heterodyned again
with a second local oscillator signal (44.395MHz) with in IC9
to become a 455kHz second IF signal. The second IF signal is
fed through a 455kHz ceramic filter, CF1 (Wide), CF2 (Nar-
row) to further eliminate unwanted signal, and the quadrature
detection circuit FM-detects the signal to produce a base-
band signal and output it from pin 11.
2-4. Audio Amplifier
The audio amplifier circuit is located in control section of
TX-RX unit (X57-695 B/2). The recovered audio signal ob-
tained from IC9 is amplified by IC608, input to the AINR ter-
minal of CODEC IC (IC614), and audio processed by DSP
(IC618).
The processed audio signal from AOUTR terminal of
IC614 is amplified by IC619 (B/2) to a sufficient level, anti-
aliasing filtered by IC619 (A/2). The audio signal goes to an
electronic volume (IC615) V3/V4, to the input of multiplexer
IC (IC622), and is amplified to drive a loudspeaker by an audio
power amplifier (IC629). The 4W audio output can be pro-
vided to external 4 ohms speaker through the 15-pin test con-
nector “SPO, SPG” on the rear panel.
2-5. Squelch Circuit
The output signal from IC9 enters FM IC again, then
passed through a band-pass filter.
The noise component output from IC9 is amplified by Q7
and rectified by D5 to produce a DC Voltage corresponding to
the noise level. The DC voltage is sent to the analog port of
the CPU (IC604).
IC9 outputs a DC voltage (RSSI) corresponding to the in-
put of the IF amplifier.
3. Transmitter Circuit
The transmitter circuit consists of the following circuits : 3-
1 microphone circuit, 3-2 modulation level adjustment circuit,
3-3 driver and final power amplifier circuit, 3-4 automatic
power control circuit, 3-5 RF power down detect, and 3-6 fan
action control circuit.
3-1. Microphone Circuit
The signal from the microphone is passed through AGC
circuit located in display unit (X54-333), so that it does not
saturate. This circuit consists of IC501, D501, D502, Q501,
and Q502. The AGC is operated by controlling the + and –
side levels of amplitude using the current obtained by posi-
tive and negative detection of the amplified audio signal. The
audio signal goes to control section of TX-RX unit (X57-695 B/
2) from display unit (X54-333).

The transmit audio signal goes to the input of the multi-
plexer IC (IC605) for microphone muting. The audio signal is
amplified by IC610, input to the AINL terminal of CODEC IC
(IC614), and audio processed by DSP (IC618). The processed
audio signal from the AOUTL terminal of IC614 is amplified
by IC616 (A/2) to a sufficient level, anti-aliasing filtered by
IC616 (B/2), and amplified by the summing amplifier IC611
(A/2).

Automatic Power Control Circuit and Transmitter
The automatic power control (APC) circuit stabilizes the
transmitter output power at a pre-determined level, and con-
sists of forward/reverse power detector circuits, and switch-
ing transistor Q8. The forward/reverse power detector cir-
cuits detects forward RF power and reverse RF power to DC
voltage, and consists of a CM coupling type detection circuit
formed by a strip line, RF detector D4/D5, and DC amplifier
IC1 (A/2).
The voltage comparator (IC1 B/2) compares the above de-
tected voltage with a reference voltage, set using the micro-
processor and IC6 located in the TX-RX unit. An APC voltage
proportional to the difference between the sensed voltage
and the reference voltage appears at the output of IC1. This
output voltage controls the gate voltage for the drive ampli-
fier Q4 and final amplifier Q5, which keeps the transmitter
output power constant.
3-5. RF Power Down Detect
When the transmitter output power has dropped to or be-
low the preset values (High Power : about 20W, Low Power :
about 10W) in “RF Power Down Detect” adjustment, IC604
(CPU : X57-695) detects the drop in power and outputs a
Low-level (default) signal to the AUX out port.
3-6. Fan Action Control Circuit
If fan action is set to “Temperature”, the cooling fan is
turned ON or OFF according to temperature.
If the ambient temperature of the final unit exceeds
approx. 35°C, the output from the temperature detection IC2
changes from H to L. This signal is sent to the CPU (IC604)
by Q602 in the TX-RX unit B/2 (control section), and the out-
put from pin 13 (FAS) of IC7 in the TX-RX unit A/2 controlled
by the CPU goes H.
This signal turns Q9 in the final unit ON to run the cooling
fan. It has a hysteresis of approx. 2°C by IC1. If fan action is
set to “Continuous”, the fan operates continuously, but Q9
stays ON.

4. PLL Frequency Synthesizer
The PLL frequency synthesizer circuit consists of the fol-
lowing circuits : 4-1 receiver PLL circuit, 4-2 transmitter PLL
circuit, and 4-3 unlocked detector circuit.
4-1. Receiver PLL
The receiver PLL circuit is located in VCO unit A3 (X58-
478) on TX-RX unit (X57-695 A/2), and consists of VCXO X2,
VCO’s (Q350 and Q351), a single-chip PLL IC IC300, buffer
amplifier Q355, and high-frequency amplifier Q302.
The VCXO generates 16.8MHz. The frequency stability is
within ±1.5ppm (Temperature range of –30 to +60°C). The
frequency tuning of the VCXO is 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 through the pin 7 of the VCO.
The first local oscillator is a lower heterodyne local oscilla-
tor, and the VCO oscillator frequency is 190.85 to 218.85MHz
(C), 180.85 to 194.85MHz (C2). Two VCOs cover the two
bands : Q350 covers the lower band and Q351 VCO covers
the upper band.
The oscillator frequency is controlled by applying the VCO
control voltage, obtained from the phase comparator to the
varactor diodes.

CIRCUIT DESCRIPTION / !
4-2. Transmitter PLL
The transmitter PLL circuit is located in VCO unit A2 (X58-
479) on TX-RX unit (X57-695 A/2), and consists of VCXO X3,
VCO’s (Q350 and Q351), a single-chip PLL IC IC300, buffer
amplifier Q355, and high-frequency amplifier Q302.
The VCXO generates 16.8MHz. The frequency stability is
within ±2.0ppm (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 through the pin 7 of the VCO.
The VCO oscillator frequency is 146.00 to 174.00MHz (C),
136.00 to 150.00MHz (C2). Two VCOs cover the two bands :
Q350 covers the lower band and Q351 VCO covers the upper
band.
The oscillator frequency is controlled by applying the VCO
control voltage, obtained from the phase comparator to the
varactor diodes.
4-3. Unlock Detector Circuit
If a pulse signal appears at the LD pin of IC300, an unlock
condition occurs, causing the voltage applied to the pin of the
microprocessor to go low. The names of this pin are LDT for
TX PLL and LDR for RX PLL. When the microprocessor de-
tects this condition, the transmitter is disabled.

5. Control Circuit
The control circuit mainly located in the control section of
TX-RX unit (X57-695 B/2) consists of the following : 5-1 CPU,
5-2 memory circuit, 5-3 CPU clock shift, 5-4 shift register cir-
cuit, 5-5 display circuit, 5-6 DSP circuit, 5-7 base-band circuit,
5-8 RS-232C circuit, and 5-9 power supply circuit.
5-1. CPU
The CPU (IC604) is a 16bit single-chip microcomputer con-
taining a 32k ROM and 3k RAM. This CPU controls the flash
ROM, the DSP, the receiver circuit, the transmitter circuit,
the control circuit, and the display circuit and transfers data to
or from an external device.
5-2. Memory Circuit
IC609 has a flash ROM with a capacity of 2M bits that
contains the control program for the CPU, the signal process-
ing program for DSP and data such as channels and operating
features.
This program can be easily written from an external de-
vice. Data such as the operating status are programmed into
the EEPROM (IC600).
5-3. CPU Clock Shift
There are the 14.754MHz clock for the CPU (IC604) and
the 16.515MHz clock for the DSP (IC618) at the control sec-
tion of TX-RX unit (X57-695). When these clocks are multi-
plexed with the reception frequency, they become an inter-
nal beat signal. To prevent this, by tuning Q600 and Q604 on
the clock frequency is shifted. (Shift on/off can be set
through programming.)

5-4. Shift Register Circuit
Serial data is sent to the shift register (IC502 to IC505 lo-
cated in display unit, IC602, IC623, IC7 located in TX-RX unit)
from the CPU (IC604) to control various functions in the unit.
5-5. Display Circuit
The display circuit (X54-333) contains two 7-segment
LEDs D506, D507 (orange), D503 (red : transmission), two-
color D504 (green : busy, orange : selective called), two-color
LED D505 (red : backup, green : main DC), LEDs in switches
S501 to S506, IC502, IC503, IC504, and IC505 to display this
model channels and states.
IC502 to IC505 are shift registers which convert serial data
from the CPU to parallel data and light LEDs.
Q507, Q510, and Q511 are switching transistors which
control two-color LED D505.
IC506, and IC507 are three-pin power supply ICs which
produce power used for the display circuit.

5-6. DSP
The DSP circuit filters transmit/receive audio signal and
encode/decodes signaling (QT, DQT). This circuit consists of
IC618, IC612, IC613, IC614, IC603, IC606, IC608, IC610,
IC616, and IC619.
The receive signal DET is converted from analog to digital
by IC614 with a sampling frequency of 16.128kHz. The digi-
tized audio signal is sent to DSP IC618 to process the signal-
ing signal and audio signal. The processed digital audio signal
is fed to CODEC IC613, converted from digital to analog, and
the analog signal is output from pin 16 (AOUTR). Then, the
audio signal is amplified by IC619 (B/2), passes through the
IC619 (A/2) low-pass filter, and goes to an electronic volume
IC615.
The transmit audio signal coming from IC605 is amplified
by IC610, fed to pin 3 (AINL) of CODEC IC614, and converted
from analog to digital at a sampling frequency of 16.128kHz.
The digitized transmit audio signal is AGC-processed, pre-
emphasized and filtered at 300Hz to 3kHz by DSP IC618, and

the resulting signal is fed back to CODEC IC614, and con-
verted from digital to analog, and the analog signal is output
from pin 15 (AOUTL). The transmit signal from AOUTL is
amplified by IC616 (B/2), passes through the IC616 (A/2) low-
pass filter, and goes to the IC611 (A/2) summing amplifier.
IC613 is a counter IC and the clock required for the
CODEC and DSP is generated by dividing the 16.515MHz
clock signal produced by DSP IC618.
IC603 and IC606 are interface IC between the CPU oper-
ated at 5.0V and the DSP operated at 3.3V.
5-7. Base-Band Circuit
The base-band circuit switches between the modulation
signal to the transmitter circuit, and remote audio and adjusts
their levels. This circuit consists of IC605, IC607, IC611,
IC615, and IC617.
Modulation inputs include local microphone input, low-
speed data (LSD), high-speed data (HSD), external audio in-
put (TA), and external data input (TD), and demodulation out-
puts include receive audio output (RA), and receive data out-
put (RD).
The multiplexer (IC605) changes signals, the electronic
volume (IC615) adjusts the level, and the operational ampli-
fier (IC607, IC611, IC617) amplifiers and sums signals.
5-8. RS-232C Circuit
The RS-232C circuit connects the RS-232C serial port of a
personal computer directly to this model to perform FPU op-
eration. The FPU operation can also be performed by con-
necting a programming cable (KPG-46) to the local micro-
phone on the front panel. But, if the D-sub connector on the
rear panel is used, the programming cable is not required.
The 232C driver IC (IC620) changes the TTL-232C level. The
firmware can only be rewritten with the local microphone on
the front panel.

5-9. Power Supply Circuit
The power supply circuit generates power to operate the
CPU, DSP, flash ROM, bi-directional buffer, and base-band
circuit. This circuit consists of IC624, IC625, IC626, IC627,
IC628, and IC630.
6. DC Power Supply Circuit
6-1. DC Source Switching Relay Circuit
1. The final unit contains a relay (K1) for switching between
the Main DC and Backup Battery.
If an external power source is connected to the Main DC
terminal, the Backup terminal is isolated by the relay. If
the Main DC turns OFF due to power failure, it is switched
to the Backup terminal by the relay.
The CPU monitors which is used, Main DC or Backup Bat-
tery.
2. Trickle charge circuit
If both Main DC and Backup Battery are connected, trickle
charging of 0.5A max. can be performed from the Main
DC power supply to the Battery.
(The default is OFF. See the Modification section for infor-
mation on the modification method.)
The battery is charged from the Main DC with D8, D9 and
R61. If it exceeds 0.5A, the charging circuit is turned OFF
by D9.
6-2. SB Switching Relay Circuit
1. SB (Switched +B) is supplied through the relay (K1) in the
TX-RX unit A/2.
When S507 (DC source switch) in the display unit is
turned ON, the relay (K1) is turned ON to output SB.
2. If +B exceeds 18V, the relay is forcibly turned OFF by D12
and Q25 to interrupt the power and protect the main unit.

Fine-Tuning the TKR-750
“ADJUSTMENT” items described in the Service Manual
for the TKR-750 give the factory-default adjustment proce-
dure covering all adjustment items.
However, it is not necessary to adjust all the items when
adjusting the power, deviation, receiver sensitivity, etc at the
frequency of the channel to be used by the TKR-750.
Adjustment procedure at the frequency of the
channel to be used
1. Program a channel frequency using the FPU (KPG-
91D(C)).
2. From the FPU menu, select in the order of “EDIT”, “Test
Frequency” and “CH paste” to rewrite the test frequency
from the factory-default to the one to be used for the
channel.
Erase all channel frequencies rewritten through this op-
eration and press the ENTER key to retrieve the factory-
default test frequency.
Refer to the explanation given under HELP for the FPU
(KPG-91D(C)) for details.
3. Check whether the frequency rewritten under the “Test
mode” of the FPU (KPG-91D(C)) is correct, then select the
item to be adjusted from the FPU (KPG-91D(C)) menu and
adjust the set value for the item to an optimum value with
the “TEST” tag.
Note :
After adjustment of the “Max. Deviation”, be sure to
check the “DQT balance”.
1. Setting 1) Connect the unit to a suitable DC power supply.
2. Write test 1) Turn the DC source switch on after connecting a PC and FPU cable to the radio. → “E1” appears on LED display
frequency 2) Write the test and shipping frequency to the radio. → Green (BUSY) LED lights up
3) End of test frequency writing.
3. Setting 1) Connect the unit to a suitable DC power supply.
2) Turn the power switch on after connecting a PC and FPU cable to the radio.
3) Start up the program for the adjustment.

Confirmation and Alignment of Set-up to
Prevent Receiver Desensitization
1. Confirmation of Duplexer alignment
The duplexer allows the Repeater to simultaneously trans-
mit and receive. To accomplish this, in the programmed re-
ceive frequency, the transmit frequency must be notched or
suppressed by 75dB or more. Additionally, on the pro-
grammed transmit frequency, the receive frequency must be
notched or suppressed by 75dB or more. The following fig-
ures are examples of Duplexer alignment using a spectrum
analyzer.
2. Confirmation of Repeater Desensitization
The following figure is a Test set-up for Repeater Desensi-
tization.
After this Test set-up is completed, confirm the Repeater
Desensitization as mentioned below.
1) Disable the repeater mode.
2) Adjust the level of the RF generator until 12dB SINAD is
reached.
3) Increase the output of the RF generator by 1dB. (This in-
creases the SINAD.)
4) Enable the repeater mode.
5) Read the SINAD level. It should not drop below 12dB
SINAD. If the SINAD is less then 12dB, check the tight-
ness of the connectors and the tuning of duplexer.
