5. Simplex/Duplex Operation
The Simplex/Duplex function is used to specify whether
the channel is used as simplex (receiver muted during transmit) or duplex (receiver unmuted during transmit). If the
channel has same TX/RX frequency, it can operate only in
Simplex mode.
6. Repeater/Base Station Operation
The Repeat function is used to specify whether the channel is used as a repeater or as a base station. A repeater
simultaneously and automatically re-transmits its received
audio, a duplex base station has independent simultaneous
transmit and receive paths, a simplex base station are mutually exclusive transmit and receive paths.
7. Signalling Feature
8
Start up
The Multi Table function enables the TKR-750 to decode
any one of the 16 QT/DQTs pre-programmed into the Multi
Table. When receiving a signal (repeater operation), the repeater uses the QT/DQT encode which corresponds to the
decoded QT/DQT as set in the Multi Table. In the Multi
Table, signalling pair of “No.1” (first column) is defined as
“Primary”. A receiving signalling (if it is contained within
No.1 to No.16) is defined “Current”.
From No.2 to No.16, signalling pairs that can be changed
between “Main Table” and “Sub Table” using AUX I/O
Ports 1-4 are assigned as “Multi Table Select” and the Multi
Table Main, the Multi Table Sub or the Multi Table Main/Sub
function is executed. When AUX I/O Ports 1~4 are set for
“Multi Table Select”, these are 4 bit Binary Coded Decimal
(BCD) inputs .AUX I/O 1 is a least significant bit (LSB), and
“1101” input (LSB on the right side) signifies the Table No.2
and “1100” input signifies the Table No.3.
7-1. Multiple QT/DQT
7-2. Encode Tone in Multiple
The TKR-750 can function as a multiple-QT/DQT decode/
encode unit for operation as a community repeater or multiple-QT/DQT base station. Two Multi Tables, called Main
and Sub, can be created, each consisting of 16 decode/encode combinations.
When Local Microphone PTT or External PTT is active
while the repeater is in use or the duplex-base station is receiving, the encode signalling is determined according to
Encode Tone in Multiple function. The simplex-base station
always transmits the “Primary” encode QT/DQT.
TKR-750
OPERATING FEATURES
Current : When any PTT as described above is active
while the repeater is in use or the duplex-base station is receiving, the “paired” encode QT/DQT associated with receiving QT/DQT is transmitted. When any PTT is active
while the repeater or the duplex-base station is in idle period, the “Primary” encode QT/DQT is transmitted.
Primary : When any PTT (provided that the Priority of any
PTT is higher than the Priority of Repeat PTT) is active while
the repeater is in use, the encode QT/DQT changes
“paired” encode QT/DQT to “Primary” while continuing to
transmit. When any PTT is active while the repeater is in
idle period, the “Primary” encode QT/DQT is transmitted.
In the base station, the “Primary” encode QT/DQT is always
transmitted regardless of the receiver status.
7-3. QT Reverse Burst Time
During repeat with QT tones, the repeater re-transmits a
phase-shifted burst of the QT tone (“reverse burst”) when it
detects the radio using the repeater has un-keyed and also
sent a reverse QT burst (squelch-tail elimination). This
mutes a receiving radio’s speaker audio before its receiver
circuit shuts off causing squelch tail noise in the speaker
audio. The TKR-750 can select the time between 140 to 200
ms that the QT reverse burst is sent. Typically this time
should not have to be adjusted from the default value. The
transmission of the QT reverse burst can be also inhibited if
the QT Reverse Burst function is set to “No”.
7-4. DQT Turn Off Code Time
During repeat with DQT tones, the repeater re-transmits
a specific turn-off code when it detects the radio using the
repeater has un-keyed and also sent the turn-off code
(squelch-tail elimination). This mutes a receiving radio’s
speaker audio before its receiver circuit shuts off causing
squelch tail noise in the speaker audio.
The TKR-750 can select the time between 140 to 200ms
that the DQT turn-off code is sent. Typically this time should
not have to be adjusted from the default value.
7-5. Off Hook Decode
The TKR-750 is able to decode QT/DQT regardless
whether the local microphone is in the on- or off-hook condition. When the Off Hook Decode function is enabled, the
TKR-750 is capable of QT/DQT decode even though the microphone is in the off-hook condition (or a local microphone
is not installed).
8. Scan Feature
8-1. Scan Operation
Providing that the TKR-750 contains two or more non-priority ADD channel or one or more non-priority ADD channel
and Priority channel, it starts scanning once the Scan On
function is executed and displays “SC” on the 7-seg LED.
Scanning stops temporarily if any following conditions be
come valid.
1) if a RF carrier and a valid QT/DQT is present. The receiving channel number is displayed and the received audio is
heard from a speaker.
2) if a RF carrier is present, providing that the Monitor On
function is executed.
3) if the Squelch Off function is executed. Scanning stops
on the channel being scanned when Squelch Off is executed, the channel number is displayed and the received audio is heard from a speaker.
4) if a local microphone’s hook is in off hook status, providing that the Off Hook Scan function is set to Disable.
Scanning stops on the Revert channel, but the audio is
not heard until a valid signal is received.
When the received call is ended, scanning automatically
resumes after the period set in Dropout Delay Time function
has expired. When the Scan Off function is executed, the
TKR-750 inhibits scanning and displays the selected channel.
8-2. Scan Sequence
1) Normal Scan : When no Priority channel is set, scanning
of ADD channels is done in ascending order.
2) Single Priority Scan : The Priority channel is set as either
a fixed channel or a selected channel. When Priority
channel is set, Priority channel and non Priority channel
are scanned by turns. When scanning stops on the non
Priority channel, calls from the Priority channel are still
checked at set intervals while scanning is stopped. This
operation is called Look Back and the interval period is
selected by the Look Back Time function.
8-3. Revert Channel
The Revert channel is a channel that is used to transmit
during scanning. The time from the end of transmission on
Revert channel to the time scanning automatically resumes
is set in Dwell Time function. The Revert channel types are
Last Called, Last Used, Selected, Selected + TalkBack, Priority, and Priority + TalkBack.
1) Last Called : The TKR-750 reverts to the channel upon
which a call was last received even if scanning has resumed (power on default = selected channel).
2) Last Used (with TalkBack) : The TKR-750 reverts to the
channel that was last transmitted on (power on default =
selected channel). However, if a call is received on a
channel other than the last transmit channel and PTT is
pressed before scanning resumes, the transceiver “talks
back” on the current receive channel.
3) Selected : The transceiver reverts to the channel set by
the function prior to scan initiation.
4) Selected+TalkBack : The TKR-750 reverts to the channel
set by the Channel ‘X’ functions or Channel Select function prior to scan initiation. However, if a call is received
on a channel other than the selected channel and PTT is
pressed before scanning resumes, the transceiver “talks
back” on the current receive channel.
5) Priority : The TKR-750 always reverts to the Priority channel.
9
TKR-750
OPERATING FEATURES
6) Priority+TalkBack : The TKR-750 always reverts to the
Priority channel. However, if a call is received on a channel other than the Priority channel and PTT is pressed
before scanning resumes, the transceiver “talks back”
on the current receive channel.
9. CW ID and Message
The TKR-750 contains internal automatic station identifiers. The CW ID (Morse code) is set and transmitted on a
per-channel basis. The CW ID is transmitted when the interval period is reached (TX Interval Time function), the
channel is changed (CW ID on Channel Change function) or
CW ID Onfunction is executed. When CW ID is activated by
any functions described above, it is actually sent after the
total time of TX Delay Time (not applied to CW ID On function) and CW Modulation Delay Time has expired. TX Delay
Time is a period from CW ID is activated to the transmitter is
keyed.
CW Modulation Delay is a period from the transmitter is
keyed to the CW ID tone is sent. The CW ID tone is routed
to the Receive Audio (RA) port and a speaker if the Send CW
ID to RA function is set to Yes. The TKR-750 contains 8
message banks for CW Message. CW Message 1 to 8 is
transmitted on the current channel when the CW Message
1 to 8 On function is activated, respectively.
10. PTT Priority
A number of keying sources can be used to cause the
TKR-750 to transmit.
The transmit audio path is switched according to their
keying sources and when PTTs is simultaneously activated,
the transmit audio path related to the PTT with higher priority is given priority. These are Local Microphone PTT, External PTT, and Repeat PTT.
11. Time Out Timer
The Time Out Timer function determines the period of
time users can continuously transmit. When the selected
period expires, the transmission is inhibited.
12. Repeat Hold Time
The Repeat Hold Time (hang timer) function is used to
prevent the repeater from being repeatedly keyed and
unkeyed in response to short message traffic. When a mobile transceiver unkeys, the repeater’s Hold Timer allows
the repeater to continue transmitting for a brief period while
waiting for a responding end user. If no valid QT/DQT is
detected within the Hold Timer period, the transmitter is allowed to unkey. This function determines the period of time
that the transmitter is allowed to remain keyed after the loss
of a valid QT/DQT received signal.
10
13. Take Over
The Take Over function is used to disable the external
wireline control of the repeater. When Take over function is
enabled, the external AUX inputs and Outputs, transmit audio inputs and receive audio outputs, External PTT and External Monitor lines are disabled. All AUX Input functions
assigned to any AUX Input stay in their current state. However External PTT and External Monitor switch to the “Off”
state.
14. Test Tone
The Test Tone is a single-frequency audio sine wave and
is turned On and Off by toggling Test Tone On/Off functions.
The transmitter can be modulated without a local microphone by using the test tone. When Test Tone On function
is executed and any PTT is activated, the TKR-750 transmits
the test tone with mic mute and also routes the test tone to
RA port.
15. RF Power
The TKR-750 is able to switch transmission output on a
per-channel basis. When the TX High Power function is enabled, the transmission output is set to high power.
16. Fan Action
The TKR-750 has a cooling fan. The Fan Action function
determines whether the fan is continuously operated or operates in response to high temperatures only.
17. AUX Input and Output
There are 6 programmable AUX I/O Ports 1~6 (pins
20~25) and 3 programmable AUX Input Ports 1~3 (pins 4~6)
on the rear 25 pin D-Sub connector (CONTROL I/O) and 5
programmable AUX Output Ports 1~5 (pins 10, 11, 13~15)
on the rear 15 pin TEST/SPKR connector.
The 6 programmable AUX I/O pins are primarily intended
for remote control interfaces. Each AUX I/O Port can be set
for AUX Input, AUX Output, remote Channel Select or Multi
Table Select types. The AUX Input Port can be set execute
a single input function or a set of up to three functions when
the port is activated. If the port type for an AUX I/O Ports
1~6 is set for “AUX Input”, it will also appear AUX Input
window for function programming. The input logic is fixed
as active Low.
The AUX Output Port can be set execute a single output
function. If the port type for an AUX I/O Ports 1~6 is set for
“AUX Output”, it will also appear AUX Output window for
function programming. The output logic of AUX Output can
be set as either active High or active Low by the Logic Type
function. Active High outputs a High (5V) when the programmed condition becomes valid, active Low outputs a
Low (0V) when the condition becomes valid.

OPERATING FEATURES / REALIGNMENT
18. Channel Select
AUX I/O Ports 1~4 (1 or all 4) can each be set for “Channel Select” providing up to 16 channel selection capability.
These are 1 to 4 bit Binary Coded Decimal (BCD) inputs.
AUX I/O 1 is a least significant bit (LSB). When all of AUX I/
O Ports 1~4 set to Channel Select, “1110” input (LSB on
the right side) signifies the Channel 1 and “1101” input signifies the Channel 2.When the Channel Select function is
set to any AUX I/O ports, the Channel ‘X’ function (Channel
Up, Channel Down, Channel 1, etc.)can not be set to the
AUX Input ports, but can be set to the PF Keys. Normally
the channel control is controlled by the Channel Select function. If the Take Over function is executed, the channel control is disabled to be controlled by the Channel Select and
enabled to be controlled by the PF Keys.
19. DC Power Save

off, and the audio amplifier and the DSP becomes inactive.
When the Display On function is executed while the repeater is in the DC Power Save Mode, all panel LEDs become active as normal status indicators on the repeater, and
the audio amplifier and the DSP becomes active. However,
when the Save Delay Timer A period expires, all panel LEDs
except the Power LED are turned off and the audio amplifier
becomes inactive again, and when the Save Delay Timer B
period expires, the DSP becomes inactive. When the DC
Power Save Mode is turned on or off, up to 3 functions preprogrammed into the Save On function or Save Off function
are executed in sequence.
20. Power Supply
The TKR-750 is able to use two Power sources that are
called Main and Backup. When the Power source changes

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 supply need not be connected (if an external switch is used or if
only a solar battery is used), connect it to the Backup connector, 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.

CIRCUIT DESCRIPTION
The BPF L5/L6/L7 attenuates the unwanted signals, and
sends only the necessary signal to the first mixer DBM A1.
1. Outline
The TKR-750 is a VHF/FM repeater designed to operate
in the frequency range of 136 to 174MHz.
The unit consists of receiver, transmitter, phase-locked
loop (PLL) frequency synthesizer, and control circuits.
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
intermediate frequency (IF) signal. The first IF signal is fed
through two monolithic crystal filters (XF2; Wide, XF1; Narrow) to further remove spurious signals.
2. Receiver Circuit
The receiver is double conversion super-heterodyne, designed to operate in the frequency range of 146MHz to
174MHz (K,E) or 136MHz to 150MHz (K2).
The receiver circuit located in TX-RX unit (X57-626 A/2)
consists of the following : 2-1 front-end circuit, 2-2 first
mixer, 2-3 IF amplifier circuit, 2-4 audio amplifier circuit, and
2-5 squelch circuit.
2-3. IF Amplifier
The first IF signal is amplified by Q2 and Q3, and then
enters 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 (Narrow) 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.
2-1. Front-end Circuit
The front-end circuit consists of BPF L2/L3, RF amplifier
Q1, and BPF L5/L6/L7. The helical BPF covers frequency
ranges 146 to 174MHz (K,E) and 136 to 150MHz (K2), with a
passband of 3.0MHz.

CIRCUIT DESCRIPTION
2-4. Audio Amplifier
The audio amplifier circuit is located in control section of
TX-RX unit (X57-626 B/2). The recovered audio signal obtained from IC9 is amplified by IC608, input to the AINR terminal 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, antialiasing 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
provided to external 4 ohms speaker through the 15-pin test
connector “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 input 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, and 3-4 automatic power 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 positive and negative detection of the amplified audio signal.
The audio signal goes to control section of TX-RX unit (X57626 B/2) from display unit (X54-333).
The transmit audio signal goes to the input of the multiplexer 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 (B/2) to a sufficient level, anti-aliasing filtered by IC616 (A/2), and amplified by the summing amplifier IC611 (A/2).
3-2. Modulation Level Adjustment Circuit
The output of the summing amplifier IC611 (A/2) is
passed to an electronic volume (IC615) for maximum deviation adjustment before being applied to a varactor diode in
the voltage controlled oscillator (VCO) A2 located in TX-RX
unit (X57-626 A/2).

3-4. Automatic Power Control, Circuit and Transmitter
The automatic power control (APC) circuit stabilizes the
transmitter output power at a pre-determined level, and consists of forward/reflected power detector circuits, and
switching transistor Q8. The forward/reflected power detector circuits detects forward RF power and reflected 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
detected voltage with a reference voltage, set using the microprocessor 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 amplifier Q4 and final amplifier Q5, which keeps the
transmitter output power constant.

CIRCUIT DESCRIPTION
4-2. Transmitter PLL
4. PLL Frequency Synthesizer
The PLL frequency synthesizer circuit consists of the following 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 (X58478) on TX-RX unit (X57-626 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 ± 2.0ppm (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 an upper heterodyne local oscillator, and the VCO oscillator frequency is 180.850 to
218.850MHz. 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

VCO unit (X58-478)
The transmitter PLL circuit is located in VCO unit A2 (X58479) on TX-RX unit (X57-626 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 15 of
the VCO.
The VCO oscillator frequency is 136.00 to 174.00MHz.
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 detects this condition, the transmitter is disabled.

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.
The control circuit mainly located in the control section of

CIRCUIT DESCRIPTION
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 digitized audio signal is sent to DSP IC618 to process the signaling signal and audio signal. The processed digital audio signal is fed to CODEC IC614, 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 converted 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 operated at 5.0V and the DSP operated at 3.3V.
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
Battery.
2. Trickle charge circuit
If both Main DC and Backup Battery are connected,
trickle charging of 0.5 A max. can be performed from the
Main DC power supply to the Battery.
(The default is OFF. See the Modification section for information on the modification method.)
The battery is charged from the Main DC with D8, D9 and
R61. If it exceeds 0.5 A, the charging circuit is turned
OFF by D9.

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, lowspeed data (LSD), high-speed data (HSD), external audio input (TA), and external data input (TD), and demodulation outputs include receive audio output (RA), and receive data output (RD).
The multiplexer (IC605) changes signals, the electronic
volume (IC615) adjusts the level, and the operational amplifier (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
operation. The FPU operation can also be performed by connecting a programming cable (KPG-46) to the local microphone 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
22
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.
