REALIGNMENT / INSTALLATION

TKR-851

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-851 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-851 and the per­sonal computer, and make sure that the TKR-851 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-851
lights.

8. If you want to continue programming other TKR-851s, re­peat steps 3 to 6.

Notes :

This mode cannot entered if the firmware program mode

is set to disable in the programming software (KPG-91D).

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).

INSTALLATION

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 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.

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.

Note :

Normally, write in the high-speed mode (115200 bps).

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 scram­bler. The voice from the local microphone can be modulated
in PC test mode.

CIRCUIT DESCRIPTION

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 base­band signal and output it from pin 11.

2-4. Audio Amplifier

The audio amplifier circuit is located in control section of
TX-RX unit (X57-696 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 : 3­1 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 posi­tive and negative detection of the amplified audio signal. The
audio signal goes to control section of TX-RX unit (X57-696 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 (A/2) to a sufficient level, anti-aliasing filtered by
IC616 (B/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 (X57­696 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 con­sists of forward/reverse power detector circuits, and switch­ing transistor Q8. The forward/reverse power detector cir­cuits 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
IC3 (A/2).

The voltage comparator (IC3 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 IC3. This
output voltage controls the gate voltage for the drive amplifi­ers Q3 and 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 be­low the preset values (High Power : 10 W, Low Power : 0.4
W) in “RF Power Down Detect” adjustment, IC604 (CPU :
X57-696) detects the drop in power and outputs a Low-level
(default) signal to the AUX out port.

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 IC1
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 out­put from pin 13 (FAS) of IC7 in the TX-RX unit A/2 controlled
by the CPU goes H.

CIRCUIT DESCRIPTION

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-

480) on TX-RX unit (X57-696 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 405.15 to 435.15MHz
(K), 395.15 to 425.15MHz (E).

The oscillator frequency is controlled by applying the VCO

control voltage, obtained from the phase comparator to the
varactor diodes.

4-2. Transmitter PLL

The transmitter PLL circuit is located in VCO unit A2 (X58-

481) on TX-RX unit (X57-696 A/2), and consists of VCXO X3,
VCO’s (Q350), 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 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 450.00 to 480.00MHz (K),

440.00 to 470.00MHz (E).

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.

5. Control Circuit

The control circuit mainly located in the control section of
TX-RX unit (X57-696 B/2) consists of the following : 5-1 CPU,
5-2 memory circuit, 5-3 CPU clock shift, 5-4 shift register cir­cuit, 5-5 display circuit, 5-6 DSP circuit, 5-7 base-band circuit,
5-8 RS-232C circuit, 5-9 power supply circuit, and 5-10 5-tone
decode circuit.

5-1. CPU

The CPU (IC604) is a 16bit single-chip microcomputer con­taining 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 process­ing program for DSP and data such as channels and operating
features.

This program can be easily written from an external de­vice. 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 sec­tion of TX-RX unit (X57-696). When these clocks are multi­plexed with the reception frequency, they become an inter­nal 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 lo­cated 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 : see the operation manual for de­tails of display), 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.

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 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, pre­emphasized 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) low­pass 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.

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

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.

CIRCUIT DESCRIPTION

5-10. 5-tone* Decode

The 300 to 3000Hz frequency characteristics of the signal
that enters the comparator are made flat by the circuit, and
the band is made into that band required to detect 5-tone
signal by the low-pass filter (IC632 2/2), high-pass filter
(IC632 1/2) and BEF filter (IC631 1/2). The signal made into a
square wave by the comparator (IC631), and input to the
CPU, IC604.

R831

TKR-851

IC604 checks the square wave frequency for the pres­ence of the required tone, and if the tone matches, IC604
performs the subsequent required processing.

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.

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.
