INTRODUCTION

SCOPE OF THIS MANUAL

This manual is intended for use by experienced techni­cians familiar with similar types of commercial grade com­munications equipment. It contains all required service in­formation for the equipment and is current as of the publica­tion date. Changes which may occur after publication are
covered by either Service Bulletins or Manual Revisions,
which are issued as required.

ORDERING REPLACEMENT PARTS

When ordering replacement parts or equipment informa­tion, the full part identification number should be included.
This applies to all parts : components, kits, and chassis. If
the part number is not known, include the chassis or kit
number of which it is a part, and a sufficient description of
the required component for proper identification.

PERSONNEL SAFETY

The following precautions are recommended for person­nel safety :

• DO NOT transmit if someone is within two feet (0.6

meter) of the antenna.

• DO NOT transmit until all RF connectors are secure and

any open connectors are properly terminated.

• SHUT OFF and DO NOT operate this equipment near

electrical blasting caps or in an explosive atmosphere.

• All equipment should be properly grounded before

power-up for safe operation.

• This equipment should be serviced by only qualified

technicians.

PRE-INSTALLATION CONSIDERNATIONS

1. UNPACKING

Unpack the radio from its shipping container and check
for accessory items. If any item is missing, please contact
KENWOOD immediately.

2. LICENSING REQUIREMENTS

Federal regulations require a station license for each ra­dio installation (mobile or base) be obtained by the equip­ment owner. The licensee is responsible for ensuring trans­mitter power, frequency, and deviation are within the limits
permitted by the station license.

Transmitter adjustments may be performed only by a li­censed technician holding an FCC first, second or general
class commercial radiotelephone operator’s license. There
is no license required to install or operate the radio.

3. PRE-INSTALLATION CHECKOUT
3-1. Introduction

Each radio is adjusted and tested before shipment. How­ever, it is recommended that receiver and transmitter op­eration be checked for proper operation before installation.

3-2. Testing

The radio should be tested complete with all cabling and
accessories as they will be connected in the final installa­tion. Transmitter frequency, deviation, and power output
should be checked, as should receiver sensitivity, squelch
operation, and audio output. QT equipment operation
should be verified.

4. PLANNING THE INSTALLATION
4-1. General

Inspect the vehicle and determine how and where the
radio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crush­ing wiring, and radio installation to prevent overheating.

4-2. Antenna

The favored location for an antenna is in the center of a
large, flat conductive area, usually at the roof center. The
trunk lid is preferred, bond the trunk lid and vehicle chassis
using ground straps to ensure the lid is at chassis ground.

4-3. Radio

The universal mount bracket allows the radio to be
mounted in a variety of ways. Be sure the mounting surface
is adequate to support the radio’s weight. Allow sufficient
space around the radio for air cooling. Position the radio
close enough to the vehicle operator to permit easy access
to the controls when driving.

4-4. DC Power and wiring

1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse

to blow. Check the vehicle ground polarity before installa-

tion to prevent wasted time and effort.

2. Connect the positive power lead directly to the vehicle

battery positive terminal. Connecting the Positive lead to

any other positive voltage source in the vehicle is not rec-

ommended.

CAUTION

If DC power is to be controlled by the vehicle ignition
switch, a switching relay should be used to switch the posi­tive power lead. The vehicle ignition switch then controls
DC to the relay coil.

3. Connect the ground lead directly to the battery negative

terminal.

4. The cable provided with the radio is sufficient to handle

the maximum radio current demand. If the cable must be

extended, be sure the additional wire is sufficient for the

current to be carried and length of the added lead.

5. INSTALLATION PLANNING – CONTROL STATIONS
5-1. Antenna system

Control station. The antenna system selection depends
on many factors and is beyond the scope of this manual.
Your KENWOOD dealer can help you select an antenna sys­tem that will best serve your particular needs.

5-2. Radio location

Select a convenient location for your control station radio
which is as close as practical to the antenna cable entry
point. Secondly, use your system’s power supply (which
supplies the voltage and current required for your system).
Make sure sufficient air can flow around the radio and power
supply to allow adequate cooling.

SERVICE

This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and align­ment procedures contained in this manual.

Note

When you modify your radio as described in system set­up, take the following precaution.

The rating of pin 7 (SB) of the accessory connector cable
(KCT-19) on the rear of the radio is 13.6V (1A). Insert a 1A
fuse if you use the SB pin for external equipment.

OPERATING FEATURES

3. Scan Operating

■ System Scan

System scan can be selected with the “Scan” key by pro­gramming the scan feature. When the “Scan” key is
pressed and the “SCN” mark appears, scan mode in en­tered. Scanning starts from the system following the cur­rently displayed system. When a call is received, scanning
stops, and the system and group are displayed.

When programming key is touched during scanning, the
scan stops and the revert system or group can be changed.
Scanning resumes one second after the key is released.

There are two types of system scan.

• Fix System Scan

All the set systems except locked-out ones are scanned.
If the Del/Add feature is assigned to the programmable key,
it can be controlled from the front panel.

• List Type System Scan

A scan list can be set for each system.

The list to be scanned can be changed by changing the
display system.

If many systems have been set, the scan speed can be
increased by narrowing the systems to be scanned with
scan lists.

■ System Lockout

The system lockout feature is used to lock systems out
of the scan sequence, and can be selected by programming
in the following two ways;

• Fixed Lockout

The system to be locked out is selected by programming.
When a locked system is selected, the Delete (
appears on the left of the SYSTEM indicator. The revert sys­tem is scanned even if it is locked out. If there is a locked
system, the Delete (
ning.

) indicator flashes during fixed scan-

• User Selectable Lockout

If the scan lockout feature is programmed to a key, the
user can lock systems out of the scan sequence with the
key. To lock a system out of the scan sequence, press the
key when the system is displayed. The Delete (
is displayed on the left of the SYSTEM indicator.

To unlock a system, select the system and press the key.
The Delete (
tem has returned to the scan sequence. The revert system
is scanned even if it is locked out. If there a locked system,
the Delete (
systems are locked out, the scan stops and only the revert
system is received.

■ Drop-out Delay Time (Scan Resume Time)

If a call is received during scan, the scan stops. The scan
resume time can be programmed as 0 to 300 seconds in
one-second increments. The default value is 3 seconds.

) indicator

) indicator

■ Dwell Time

The dwell time is the time after transmission ends until
the scan resumes in scan mode. It can be set 0 to 300 sec­onds by programming. The default value is 3 seconds.

■ System/Group Revert

System/group revert can be programmed for one of the
following;

• Last Called Revert

The system or group changes to the revert system or
group when a call is received with the system or group be­ing scanned.

• Last Used Revert

If a system/group call is received during scanning and the
PTT button is pressed for transmission and response within
the drop out delay time, the system or group is assigned as
the new revert system or group.

• Selected Revert

If the system/group was changed while scanning, the
newly selected system/group.

• Selected + Talkback Revert

If the system/group was changed while scanning, the
newly selected system/group. The transceiver “talks back”
on the current receive group.

■ Scan Massage Wait

The time for staying with the home repeater that re­ceives a signal during system scan and monitoring data
messages can be programmed. If there is no signal from
the home repeater, the system is scanned for about 50ms.
If there is a signal, three data messages are monitored.
Normally, three data messages are monitored for each sys­tem, and it can be increased in multiples of three data mes­sages per line to up to eight lines.

If the repeater data message indicates that there is no
call, data monitoring is terminated and the home repeater of
the next system is scanned.

■ Group Scan Operation

Group scan can be programmed for each group. In addi­tion to the ID codes of the selected group, the ID codes of
the other groups that are permitted for group scan are de­coded. (The two fixed ID and block decode codes are al­ways decoded.)

If, during group scanning, a call is received with one of
the selectable group ID codes for which group scan is en­abled, the group display indicates the group number that the
call came in with. That group then becomes the new se­lected group. Group scan resumes after the specified drop­out delay time or dwell time shared by the system scan
elapses.

■ In Conventional System

If QT or DQT is set for the group, the groups, including

signalling, are scanned.

In case of the priority group is set in conventional system,
if a group scan (including group scan during a system scan)
temporarily stops (receiving) in a group that does not have
priority, a look back is performed to the priority group. Look
back is performed according to the look back time A and B
settings. If a call is received on the priority group, reception
immediately switches to the priority group.

4. Details of Features

■ Time-out Timer

The time-out timer can be programmed in 15 seconds
increments from 15 seconds to 10 minutes. If the transmit­ter is keyed continuously for longer than the programmed
time, the transmitter is disabled and a warning tone sounds
while the PTT button is held down. The alert tone stops
when the PTT button is released.

■ Sub LCD Display

You can use 3-digit the display to display the system
number or group number. It is useful when the main (12­digit) display indicates system, group name or other func­tions.

■ Selective Call Alert LED

You can select whether or not the LED on the transceiver
flashes in an orange color when selective call was occurred.

■ Off Hook Decode

If the Off hook decode function has been enabled, re­moving and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.

■ Timed Power Off

This function works as “Automatic Power Switch Off”.

Timed power off timer starts from the ignition-off. After
the timer expires, the radio will automatically turn off. The
timer will be reset if the ignition is turned on and off.

This function requires ignition-sense. Connect the igni­tion-line to the 9-pin connector which is located at the rear of
the radio.

After the timer expires, press the power switch to turn
on the radio.

■ Horn Alert

Horn alert can be set to on or off for each group. If horn
alert has been set to YES for a group and DEC ID/QT/DQT/
MSK matches, the horn alert, HOR. is turned on and off.
The group for which the optional signalling is set works by
ANDing the decode ID/QT/DQT/MSK with the optional sig­nalling.

Either continuous or non-continuous operation can be set
by the FPU. The horn alert port is enabled or disabled as
follows;

Off hook horn alert

Enable Yes Yes

Disable No Yes

Hook off Hook on

■ PTT ID

PTT ID provides a DTMF or MSK (FleetSync™ : Fleet-ID)
ANI to be sent with every time PTT (beginning of transmis­sion, end of transmission, or both).

You can program PTT ID for each group. You can pro­gram PTT ID as “on” or “off” when “DTMF” is selected for
the PTT ID type. You can program a PTT ID as “own”, “sel”
or “off” when “MSK” is selected for the PTT ID type. The
contents of ID are programmed for each transceiver.

The timing that the transceiver sends ID is program­mable.

BOT : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission.

EOT : DTMF ID (EOT)/MSK ID is sent on end of transmis-

sion.

Both : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission and DTMF ID (EOT)/MSK ID is sent on end

of transmission.

■ Radio Password

When the password is set in the transceiver, user can not
use the transceiver unless enter the correct password.

This code can be up to 6 digits from 0 to 9 and input with
the key, and “SCN” key.

■ Non-continuous

The horn alert port, HOR, is turned on and off as follows;

HOR

■ Free System Ringback

This feature is available only when a telephone intercon­nected ID code is selected. If a busy tone sounds when the
PTT button is pressed, the transceiver enters this mode au­tomatically.

When the PTT button is released, a beep sounds for
400ms to indicate that the mode has been entered. If the
scan is on, it is resumed (the “SCN” mark goes on). When
any repeater becomes available, a ringing tone sounds and
this mode ends.

The mode is terminated when the system, group, scan,
PTT, key is changed.

■ System Search

This feature can be programmed to automatically access
other programmed systems when the selected system can­not be accessed. If an intercept tone sounds when the PTT
button is pressed after setting the mode, the transceiver
has entered the mode.

If the group ID is a telephone interconnect ID, the trans­ceiver then attempts to access, in succession, other sys­tems that have a telephone interconnect ID in the revert
group location. If the group ID is a dispatch ID, the trans­ceiver attempts to access other systems that have a dis­patch ID programmed in the revert group location.

If there is no system to be accessed, an intercept tone
sounds, the mode is terminated, and the transceiver returns
to the first system. If the access is successful, the mode is
terminated, and the searched system becomes the new se­lected system (If during scanning, the scan stops).

Q27

■ Call Indicator

The call indicator can be programmed for each group. In
trunked system, it can be set to respond to a selectable de­code ID or one of two fixed IDs, except block IDs. When a
call is received with a selectable decode ID, the call indicator
flashes. When a call is received with a fixed ID, the call
indicator lights continuously.

On a conventional system, the call indicator can be pro­grammed to light for each QT or DQT code. It keeps flash­ing while a call is being received. It is turned off by pressing
any front panel key.

■ Transpond

This feature can be programmed to turn on and off for
each group. If the ID of the group for which transpond is
enabled is received, two data messages (transmit ID and
turn-off code) are automatically transmitted if the PTT but­ton is not pressed as a response within the time set (0 to
300 seconds in 1-second increments). If the PTT button is
pressed within the time, the transpond is not preformed.

■ Data TX with QT/DQT

Whether programmed QT/DQT is modulated or not with
a data transmission except for Selcall. A radio unit can re­ceive a data message regardless of QT/DQT if the receiving
unit is not scanning.

■ Transmit Inhibit

The transceiver can be programmed with a transmit in­hibit block of ID codes. If an ID code within this block is
decoded the preset time before the PTT button is pressed,
transmission is inhibited. The BUSY indicator lights and a
busy tone sounds until the PTT button is released to indicate
that transmission is not possible (except clear-to talk mode).

Transmission with the group for which the encode ID is
not set is inhibited, and the busy tone is output while the
PTT button is held down, regardless of the clear-to talk set­ting.

OPERATING FEATURES

TK-980/98 1

■ Auto TEL

A telephone interconnect call can be made by simply
pressing the key by assigning this feature to the key. This
feature accesses the TEL channel of the available system
automatically.

When the key is pressed, a queue tone is output, and the
“AUTO TEL” appears on the alphanumeric display along
with a flashing handset indicator (
mode has been entered. If the TEL ID is set for the revert
system, the TEL channel of that system is accessed. If all
TEL channels are busy, an attempt is made to access the
TEL channels of another system in which the TEL ID code
has been programmed. It is repeated for 60 seconds until
the access succeeds. If the access succeeds, a dial tone
returns from the repeater. If the key is pressed again when
the queue tone is sounding, this mode is canceled.

If the access fails after 60 seconds, a deny tone is output
and this mode is terminated. When the talk ends, the revert
system/group returns. When the scan mode is effective,
the scan resumes. The Auto TEL feature can be pro­grammed to turn on or off for each system.

■ ARQ Mode

If affects Trunking mode only. Automatic Repeat
reQuest (ARQ) mode is a manner to minimize the air traffic
of data communication. Also, it enables to occupy the
trunking repeater channel for the data communication pe­riod.

5. Option Signalling

5-1. DTMF

Built-in DTMF decoder is available for option signalling.

It is possible to use individual call, group call, D.B.D.
(Dead Beat Disable). D.B.D. is used with DTMF only.

If the option signalling matches, a predetermined action
will occur.

If option signalling matches on a group which is set up
with option signalling, the option signalling indicator (
flash and option signalling will be released. The transpond
or alert tone will sound.

If the selective call alert LED is set up, the orange LED
will flash.

While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute ID/QT/DQT/Carrier.

■ AND/OR

You can select AND or OR for option signalling match

If option signalling matches a group set up with option
signalling, option signalling is released. After matching op­tion signalling, option signalling will temporarily reset auto­matically.

■ Dead Beat Disable

If the D.B.D. code matches, a predetermined action will
occur. Whether option signalling is activated or not, when
D.B.D. matches on any group, the transceiver will become
TX inhibited or TX/RX inhibited. While D.B.D. is active, if the
D.B.D. code + “#” code is received, D.B.D. will disactivate.

When D.B.D. matches, transpond will function. Alert will
not be output, and option signalling match icon will not ap­pear.

Alphanumeric Two-way Paging Function

(FleetSync™)

■ General

The Alphanumeric Two-way Paging Function
(FleetSync™) is a Kenwood proprietary protocol. It enables
a variety of paging functions.

■ ID Construction

A radio unit ID is defined by a combination of 3-digit Fleet
and 4-digit ID numbers. Each radio unit must be assigned its
own Fleet and ID numbers.

■ PTT ID

A pre-programmed unique ID (own) can be sent at the
beginning of transmission and/or the end of transmission to
identify which radio unit is on air.

When selecting (sel) for MSK ID, the radio calls he spe­cific Fleet user the same as selective call.

TK-980/98 1

OPERATING FEATURES

■ Selective Call (SELCALL)

This is a voice call to a particular individual or group of

stations.

• Example of Call Types;

[100][ALL ] : <Group Call>
All the units whose fleet number is “100” are called.
[100][1000] : <Individual Call>
The unit, whose the fleet number is “100” and ID num­ber is “1000”, is called.
[ALL][ALL ] : <Broadcast Call>
All the units are called.
[ALL][1000] : <Supervisor Call>
All ID “1000” are called regardless of their fleet number.

• Unit ID Encode Block

Encode ID Block can be set to limit manual dial ID. The
radio unit will not accept an ID other than these IDs which
are entered from the keypad. If Inter-fleet Call is enabled,
block ID setting affects each fleet group.

■ Status Message

Using a 2-digit number, you can send and receive a Sta­tus message which may be decided in your talk group. Each
Status may be displayed with 16 alphanumeric characters if
programmed in the radio. A maximum of 9 received mes­sages can be stored in the stack memory, and it can be re­viewed after reception. If the message memory becomes
full, the oldest one will be erased. The stack memory will be
cleared by turning radio power off.

• Status 80~99 (Special)

Status numbers from 80 to 99 are reserved for special
purposes. Entering these statuses from the DTMF keypad
can be inhibited.

Please notice that the following status numbers are used
for special purposes;

80~87 : Reserved for future use.

88 : Terminates to emergency mode.

89 : Request for horn alert.

90 : Remote stun on. Disable the received radio unit’s

TX.

91 : Remote stun on. Disable the received radio unit’s

TX/RX.

92 : Cancel remote stun. Enable the received radio unit’s

TX/RX.

93 : Acknowledgement status sent when the radio unit is

in stun mode (TX disabled).

94 : Acknowledgement status sent when the radio unit is

in stun mode (TX/RX disabled).

95~97 : Reserved for future use.

98 : Man down emergency status (For portable).

99 : Emergency Status.

Note : Remote stun works with DTMF D.B.D. function also.

• Automatic Status Response

If you pre-select a status number and leave the radio in
the Status Mode, it can automatically respond with the se­lected status number upon request from the base station.
(The request function is initiated by serial control on the
base station (Optional).)

■ Short Messase (Optional)

A maximum of 48 characters can be sent (External equip­ment is required). Received Short Messages will be dis­played in the same manner as a Status Message. A maxi­mum of 4 received messages can be stored in the stack
memory. In the Stack Mode, 3-digit LCD indicates the re­ceived Short Message as “M01”~”M04".

■ Long Message (Optional)

A maximum of 1024 characters can be sent (External
equipment is required). Received Long Message will not be
displayed or stacked in the radio memory but is output
through the COM (Data) port.

■ Emergency Function

Emergency status 99 will be sent at the beginning of
each emergency transmission.

• Emergency Status response

Either “Horn” or “Alert” can be selected for the called
radio unit’s response to reception of status 99 which is used
as an emergency status.

■ Other Functions

• Manual Dial

Fleet, ID and Status numbers can be entered from DTMF
keypad. (DTMF microphopne is required.)

• FleetSync™ Baud Rate

MSK data baud rate setting. The same rate must be set
as a communication partner.

1200bps :

Data communication is made in 1200bps. The communi-

cation area is much wider than 2400bps. Recommended

for repeater operation.

2400bps :

Data communication is made in 2400bps. The communi-

cation area is narrower than 1200bps, but it will decrease

the data traffic. Data rate 2400bps may not work prop-

erly depending on the repeater’s characteristic.

• Message Mode Timer

Message Mode Timer is a delay timer returning from
message/stack mode to Normal mode.

• Status/Short/Long Message on Data Group

Status/Short/Long Message transmission is made
whether on the Data System/Group.

■ Parameters

• GTC Count

Number of Go To data Channel messages to be sent be-

fore transmitting a data message if it is being made on Data
System/ Group. If a radio unit receives a GTC message, it
will move to the Data System/Group of the current system.
Increase this item to make sure the called radio unit moves
to the Data System/Group.

• Random Access (Contention)

When a channel (or all the repeater channels for Trunking

mode) is busy, radio unit will not transmit (depending on its
Busy Channel Lockout setting in conventional mode). As
soon as a channel is cleared, some transmissions may
crash. Random access is used to avoid this by employing a
random transmission sequence.

• GPS Time Mark (Per Mobile)

The amount of time from the 0 (zero) minute of the stan­dardized GPS UTC time to starting the first transmission of
GPS data. It must be set to a different value for each radio
unit to avoid a transmission crash.

• Send GPS

Pressing this key causes the transceiver to send a single
GPS data.

• GPS Report On Data Group

GPS data transmission is made on the Data System/
Group.

• Number of Retries

Number of Retries is the maximum number of retry
transmission when no acknowledgement is received in the
Maximum ACK Wait Time. Increase this item to improve
data communication reliability.

• TX Busy Wait Time

TX Busy Wait Time is the maximum amount of time be­fore giving up the data transmission when the channel (or all
the repeater channels for Trunking mode) is busy. Also, this
timer affects if it expires during Random Access period.

• Maximum ACK Wait Time

Maximum ACK Wait Time is the maximum amount of
time to wait for an acknowledgement from the called radio
unit. It is used as an interval time of retries. It must be set
greater than the ACK Delay Time of the called radio unit.

11

TK-980/98 1

OPERATING FEATURES

• ACK Delay Time

ACK Delay Time is the amount of time from the end of
receiving a data to the beginning of sending an
acknowledgement. It should be adjusted as the repeater’s
hang-up delay time. Also, it must be set less than the Maxi­mum ACK Wait Time of the calling radio unit.

• TX Delay Time (RX Capture)

TX Delay Time is the amount of unmodulated transmis­sion to let the called unit stop scanning or exit its battery
save mode. It is used only when starting a data communica­tion sequence.

• Data TX Modulation Delay Time

Data TX Modulation Delay Time is the amount of time
from the beginning of transmission to the beginning of a
data modulation. It is used every time data is transmitted.
It must be set to more than 300ms if data communication is
made in Trunking Mode.

5. PC Mode

5-1. Preface

The transceiver is programmed by using a personal com-

puter, programming interface (KPG-46) and programming
software (KPG-49D).

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 transceiver 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 transceiver to PC mode, then attach the in­terface cable.

5-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the transceiver 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-46 connects the modular microphone jack of

the Ttransceiver to the computers RS-232C serial port.

5-4. Programming Software Description

The KPG-49D programming disk is supplied in 3-1/2" disk

format. The software on this disk allows a user to program
the transceiver radio via programming interface cable (KPG-

46).

IBM-PC

KPG-46

5-5. Programming With IBM PC

If data is transferred to the transceiver from an IBM PC
with the KPG-49D, 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 RS­232C format via the modular microphone jack.

KPG-49D instruction manual parts No. : B62-1096-XX.

Note :

Normally, write in the high-speed mode.

7. Clone Mode

Programming data can be transferred from one radio to

another by connecting them via their modular microphone
jacks. The operation is as follows (the transmit radio is the
master and the receive radio is a slave).

1. Turn the master radio power ON with the [C] key held
down. If the password is set to the radio, the radio dis­plays “CLONE LOCK”. If the password is not set, the
radio displays “CLONE MODE”.

2. When “CLONE LOCK” is displayed, only the [System up/
down] key and [SCN], and [0] to [9] keys can be accepted.
When you enter the correct password, and “CLONE
MODE” is displayed, the radio can be used as the cloning
master. The following describes how to enter the pass­word.

3. How to enter the password with the microphone keypad.
If you press a key while “CLONE LOCK” is displayed, the
number that was pressed is displayed on the radio. Each
press of the key shifts the display in order to the left.
When you enter the password and press the [SCN] key,
“CLONE MODE” is displayed if the entered password is
correct. If the password is incorrect, “CLONE LOCK” is
redisplayed.
How to enter the password with the [System up/down]
key;
If the [System up/down] key is pressed while “CLONE
LOCK” is displayed, numbers (0 to 9) are displayed flash­ing. When you press the [SCN] key, the currently se­lected number is determined, and the display shifts to
the left. If you press the [SCN] key after entering the
password in this procedure, “CLONE MODE” is dis­played if the entered password is correct. If the pass­word is incorrect, “CLONE LOCK” is redisplayed.

4. Power on the slave radio.

5. Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.

6. Press the [SCN] key on the master while the master dis­plays “CLONE MODE”. The data of the master is sent to
the slave. While the slave is receiving the data, “PRO­GRAM” is displayed. When cloning of data is completed,
the mater displays “END”, and the slave automatically
operates in the User mode. The slave can then be oper­ated by the same program as the master.

7. The other slave can be continuously cloned. When the
[SCN] key on the master is pressed while the master dis­plays “END”, the master displays “CLONE MODE”.
Carry out the operation in step 4 to 6.

Frequency Configuration

The TX-RX unit (A/2) incorporates a VCO, based on a frac­tional N type PLL synthesizer system, that allows a channel
step of 12.5kHz to be selected. The incoming signal from
the antenna is mixed with a first local oscillation frequency
to produce a first intermediate frequency of 44.85MHz.

The signal is then mixed with a second local oscillation
frequency of 44.395MHz to produce a second intermediate
frequency of 455kHz. This is called a double-conversion
system. The transmit signal frequency is generated by the
PLL VCO, and modulated by the signal from the micro­phone. It is then amplified by TX amplifier and PA amplifier,
and sent to the antenna.

■ AF Signal System

The detection signal (DEO) from the TX-RX unit (A/2)
goes to the audio processor (IC504) of the TX-RX unit (B/2).
The signal passes through a filter in the audio processor to
adjust the gain, and is output to IC502. IC502 sums the AF
signal and the DTMF signal and returns the resulting signal
to the TX-RX unit (A/2). The signal (AFO) sent to the TX-RX
unit (A/2) is input to the D/A converter (IC5). The AFO out­put level is adjusted by the D/A converter. The signal output
from the D/A converter is added with the BEEP signal (BPO)
and the resulting signal is input to the audio power amplifier
(IC10). The AF signal from IC10 switches between the inter­nal speaker and speaker jack (J1) output.

■ Squelch Circuit

The detection output from the FM IF IC (IC11) is ampli­fied by IC2 and the signal (DEO) is sent to the TX-RX unit (B/

2). The signal passes through a high-pass filter and a noise
amplifier (Q503) in the TX-RX unit (B/2) to detect noise. A
voltage is applied to the CPU (IC511). The CPU controls
squelch according to the voltage (ASQ) level. The signal
from the RSSI pin of IC11 is monitored. The electric field
strength of the receive signal can be known before the ASQ
voltage is input to the CPU, and the scan stop speed is im­proved.

Receiver System

■ Outline

An incoming RF signal from the antenna terminal passes
through the antenna switch (D208, D209, and D210 are off)
and then the bandpass filter (L203). The signal is amplified
by RF amplifier Q201, and passes through the bandpass fil­ter (L207) again. The resulting signal goes to the first mixer
(Q203), where it is mixed with the first local oscillator signal
output from the frequency synthesizer to produce the first
IF 44.85MHz.

CIRCUIT DESCRIPTION

Transmitter System

■ Outline

The transmitter circuit amplifies the desired frequency. It

FM-modulates the carrier signal by means of a varicap di­ode.

■ Younger-stage circuit

The signal output from the VCO is amplified by a buffer

amplifier (Q7) and goes to the drive block. The younger­stage circuit provides a stable drive output without a need
for adjustment. The APC circuit controls voltage in the
younger final stage (Q204).

■ VCO/PLL Circuit

The TK-980/981 has a common VCO for the transmitter

and the receiver in a sub-unit (A1). It is housed in a solid
shielded case and connected to the TX-RX unit (A/2) through
CN101. A filtered low-noise power supply is used for the
VCO and varicap diodes.

The VCO is described below. It is designed so that Q101

turns on with a prescribed frequency when a reverse bias is
applied to D100 and D101 by using the control voltage (CV)
through CN101. The control voltage is changed by turning
the trimmer capacitor (TC100). The output from Q103 is ap­plied to the buffer amplifier (Q102) the output from Q102 is
applied to the doubler (Q100) to generate a VCO output sig­nal. This signal is used as a drive input signal or a local signal
of the first mixer. Since a signal output from Q100 is input
to the PLL IC, it passes through CN101 and buffer amplifier
(Q300) and goes to the PLL IC (IC300). The modulation sig­nal from CN101 is applied to D102 and passes through C106
and C107 to modulate the carrier.

The PLL IC uses a fractional N type synthesizer to im-

prove the C/N ratio and lock-up speed. The VCO output sig­nal input to the pin 5 of the PLL IC is divided to produce a
comparison frequency according to a channel step. This sig­nal is compared with the reference frequency which is out­put from the VCXO (X1). VCXO provides 16.8MHz, 1.5ppm

(–30 to +60°C) and guarantees stable performance when

the temperature changes. The output signal from the phase
comparator passes through a charge pump and an external
active LPF (Q301, Q302) in the PLL IC to generate a DC VCO
control voltage CV. Serial data (DT, CK, EP) are output from
the CPU (IC511) and shift register (IC8) in the TX-RX unit (B/

2) to control the PLL IC. The PLL lock status is always moni­tored by the CPU.

■ Unlock Circuit

During reception, the TR line goes high, the KEY line

goes low, and Q10 turns on. Q11 turns on and a voltage is
applied to the collector (8R). During transmission, the TR

line goes low, the KEY line goes high and Q13 turns on. Q12
turns on and a voltage is applied to 8T.

The CPU in the TX-RX unit (B/2) monitors the PLL (IC300)
LD line directly. When the PLL is unlocked during transmis­sion, the PLL LD line goes low. The CPU detects this signal
and makes the KEY line low. When the KEY line goes low,
no voltage is applied to 8T, and no signal is transmitted.

Fig. 6 Unlock circuit

■ Power Amplifier Circuit/Final

The transmit output signal from the VCO is amplified to a
specified level of the power module (IC400) by the drive
block (Q202, Q204). The amplified signal goes to a low-pass
filter. The low-pass filter removes unwanted high-frequency
harmonics. The resulting signal passes through the trans­mission/reception selection diode (D208), then goes to the
antenna terminal.

■ APC Circuit

The direct current that flows through the final module
(IC400) produces a voltage across resistors R127. This volt­age is applied to pin 6 of IC13 (2/2), and is input as the refer­ence voltage difference of pin 5 and amplified.

■ Key Matrix Circuit

The TK-980/981 front panel has ten keys. Each of them is
connected to a cross point of a matrix of the KEY1 to KEY7
ports of the microprocessor. The KEY5 to KEY7 ports are
always high, while the KEY1 to KEY4 ports are always low.

The microprocessor monitors the status of the KEY1 to
KEY7 ports. If the state of one of the ports changes, the
microprocessor assumes that the key at the matrix point
corresponding to that port has been pressed. Unused
points (KEY1 to KEY7) are also used for foot switch (FSW)
input.

■ Memory Circuit

The transceiver has a 2M-bit (256k x 8) flash ROM
(IC510) and an 8k-bit EEPROM (IC512). The flash ROM con­tains firmware programs, data and user data which is pro­grammed with the FPU. The EEPROM contains adjustment
data. The CPU (IC511) controls the flash ROM through an
external address bus and an external data bus. The CPU
controls the EEPROM through two serial data lines.

■ Display Circuit

The CPU (IC511) controls the shift register (IC508) and
display LEDs. When the LG line goes high when the trans­ceiver is busy, Q508 turns on and the green LED on D511
lights. In transmit mode, the LR line goes high, Q509 turns
on and the red light lights. Backlighting LEDs for the key
operation unit (D512~D517) and LCD are provided.

When the KBLC line goes high, Q512 turns on, then
Q515 and Q513 turns on, and the key illumination LED
lights. A voltage is applied to the LEDA line to turn on the
LCD backlight.

Fig. 11 Key matrix circuit

■ Encode

The QT, DQT, and LTR signals are output from LSDO of
the CPU (IC511) and go to the D/A converter (IC5) of the TX­RX unit (A/2). The DTMF signal is output from HSDO of the
CPU and goes to the audio processor (IC504). An MSK sig­nal is output from the audio processor according to the data
(AFDAT) from the CPU. The signal is summed with a MIC/
MSK signal by the audio processor (IC504), and the resulting
signal passes through an analog switch (IC506) and goes to
the TX-RX unit (A/2) (MO).

MO is summed with the external pin DI line by the sum­ming amplifier (IC3) and the resulting signal goes to the D/A
converter (IC5). The D/A converter (IC5) adjusts the MO
level and the balance between the MO and TO levels. Part
of a TO signal is summed with an output signal from pin 3
(MO) of IC5 and the resulting signal goes to the MD pin of
the VCO. This signal is applied to a varicap diode in the VCO
for direct FM modulation.

CIRCUIT DESCRIPTION

■ Decode

The signal (DEO) detected by the TX-RX unit (A/2) passes
through two low-pass filters of IC501, goes to LSDI of the
CPU (IC511) to decode QT, DQT, and LTR. The DTMF signal
is decoded by a dedicated IC (IC507) and the resulting signal
is sent to the CPU (IC511) as serial data (STD).

■ D/A Converter

The D/A converter (IC5) is used to adjust TONE and MO
modulation, beep, AF volume, TV voltage, FC reference volt­age, and PC POWER CONTROL voltage level.

Adjustment values are sent from the CPU as serial data.
The D/A converter has a resolution of 256 and the following
relationship is valid:

D/A output = (Vin – VDAref) / 256 x n + VDAref

Vin : Analog input
VDAref : D/A reference voltage
n : Serial data value from the microprocessor (CPU)

■ Horn Control

The horn switch, consisting of Q4, Q5, and Q6, controls
the horn relay. It is supplied by the dealer to provide the
external horn alert function.

Q5 disables horn alert, turning on when its base is high,
to inhibit the function. Normally, the output from IC7 is low,
and Q6 is off; the base of Q4 is about 0V and Q4 is off.
When horn alert is enabled, the output from IC7 goes high
and Q6 turns on. The base current flows through R58 to Q4
to turn Q4 on. Q4 can sink a maximum of 100mA. If the
operational KAP-1 is used, it can drive up to 2A.

■ PA Switch

If the optional KAP-1 is used, the PA (Public Address)
function becomes available. In this case, the signal flow

Power Supply Circuit

When the POWER switch on the TX-RX unit (B/2) is
pressed, the PSW signal goes low. This signal is inverted by
Q26 and sent to a flip-flop IC (IC15). This IC outputs a con­trol signal when the PSW goes low. When the power turns
on, pin 1 of IC15 outputs a low signal and Q30 turns on. The
base of Q28 goes high, Q28 turns on, SB SW (Q27) turns on
and power (SB) is supplied to the set.

This circuit has an over-voltage protection circuit. If a DC
voltage of 20V or higher is applied to the power cable, D34
turns on and a voltage is applied to the base of Q31. This
voltage turns Q31 on and turns Q28 and SBSW off. This
circuit has a TIMED POWER OFF (TOF) function which can
be programmed by software.

It is controlled through pin 6 of IC7. When the TOF line
goes high, Q22 turns on and then Q25 turns on. Pin 6 of
IC15 goes high, then pin 1 goes high to turn Q27 off.

Note : In test mode, if the operation frequency is in NPSPAC
band (e.g. SYS 10), all deviations are automatically changed

as the system deviation becomes ±4kHz.

• Preparations for tuning the transceiver

Before attempting to tune the transceiver, connect the

unit to a suitable power supply.

Whenever the transmitter is turned, the unit must be

connected to a suitable dummy load (i.e. power meter).

The speaker output connector must be terminated with a

4Ω dummy load and connected to an AC voltmeter and an

audio distortion meter or a SINAD measurement meter at all
times during tuning.

• Transceiver tuning
(To place transceiver in tuning mode)

Channel appears on LCD. Set channel according to tun-

ing requirements.
