GENERAL
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 this 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 this equipment when near electrical blasting
caps or while 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.

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 installation to prevent wasted time and effort.
2. You must connect the positive power lead directly to
the positive terminal of the vehicle battery. Never
connect the lead to any other positive power source,
such as a cigarette lighter jack or fuse terminals.

CAUTION
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.

2

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. You must also connect the ground lead directly to
the negative terminal of the vehicle battery.
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.

3-1. Trunking Format
■ 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.

6

• 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.

TK-880/H
OPERATING FEATURES
■ System lockout

• Selected + Talkback revert

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;

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

• Fixed lockout

■ Scan massage wait

The system to be locked out is selected by programming.
When a locked system is selected, the Delete ( ) indicator
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 ( ) indicator flashes during fixed scanning.

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.

• 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 ( ) indicator
is displayed on the left of the SYSTEM indicator.
To unlock a system, select the system and press the key.
The Delete ( ) indicator disappears to indicate that the system has returned to the scan sequence. The revert system
is scanned even if it is locked out. If there a locked system,
the Delete ( ) indicator flashes during fixed scanning. If all
systems are locked out, the scan stops and only the revert
system is received.

■ Group scan operation

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.

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.

■ Dwell time

■ In conventional system

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.

If QT or DQT is set for the channel, the channels, 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.

■ Drop-out delay time (Scan resume time)

■ 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.

3-2. Conventional Format
■ Scan types
• Single group scan
You can scan all valid (ADD) channels in the displayed
group that can be selected with the group up/down key.

• Multiple group scan
You can scan all valid (ADD) channels in the all valid
(ADD) group.

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

TK-880/H
OPERATING FEATURES
■ SCAN start condition
One or more non-priority channels must be added to all
channels that can be scanned. The transceiver must be in
normal receive mode (PTT off).
When you activate the key programmed to the scan function, the scan starts. The scan icon “SCN” lights and “–
SCAN–” or revert channel (programmable) is indicated on
alphanumeric display.

■ Scan stop condition
The scan stops temporarily if the following conditions are
satisfied.
1) A carrier is detected, then signalling matches on channels for which receive the signalling is set by the programming software.
2) A carrier is detected on the channels for which receiving
signalling is not set by the programming software or
when the monitor (signalling cancel) function is activated.

■ Scan channel types
1) Priority channel is the most important channel for the
scan, and always detects a signal during scan and when
the scan stops temporarily.
2) Non-priority channels detects a signal during scan. For
the channels that can be selected with the group or channel up/down key when the scan does not occur, adds an
indicator “▼” lights.

■ Scan end
When you reactivate the key programmed to the scan
function during scan mode, the scan ends.
The scan icon “SCN” and “–SCAN–” or revert channel
(programmable) display goes off.

■ Priority channel setting

■ Temporarily delete/add

A priority channel can be set as follows with the programming software (KPG-49D).
1) Specify a priority channel as a fixed priority channel.
2) Make a selected channel, a priority channel.

It is possible to delete or add channel temporarily during
scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete/
add function (for example press the key), then that channel
is deleted temporarily and scan re-start immediately.
When you would like to add the deleted channel temporarily to scan sequence, select the desired (deleted) channel
during scan, activate the delete/add function (for example
press the key) before scan re-start.
That channel is added temporarily to scan sequence. The
temporary deleted or added channels are returns to pre-set
delete/add, when the transceiver exits from scan mode.

■ Scan type according to the priority channel
1) When no priority channel is set : Only the non-priority
channels are scanned.
If a non-priority channel stops temporarily, it stops until
there is no signal on the channel.
2) When priority channel is set : Either priority channel is
scanned.
If a non-priority channel stops temporarily, a priority channel signal is detected at certain intervals.
If a priority channel stops temporarily, it stops until there
is no signal on the priority channel.

■ Revert channel
The revert channel is used to transmit during scanning
and set by the programming software (KPG-49D).
1) Priority
The transceiver reverts to the priority channel.

8

2) Priority + talkback
The transceiver reverts to the priority channel.
If you press PTT during a resume timer (dropout delay
time, TX dwell time) or calling, you can transmit on current channel to answer to the call however revert channel
is set to priority channel.
After resume time, scan re-starts and transmission channel is return to priority channel.
3) Selected channel
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.
4) Last called channel
The transceiver reverts to the last called channel during
the scan.
5) Last used channel
The transceiver reverts to the last used (transmitted)
channel during scan. “Last used” revert channel includes talkback function.
6) Selected + talkback
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.

4. Details of Features
4-1. Common Trunking format and Conventional Format
■ 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.

TK-880/H
OPERATING FEATURES
■ Sub LCD display

■ Horn alert

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

In trunking format, 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 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 with the optional
signalling.
In conventional format, if you are called from the base
station using 2-tone/DTMF while you are away from your
transceiver, you will be alerted by the vehicle horn or some
other type of external alert. To turn horn alert function on,
press the [Horn Alert] key.
Either continuous or non-continuous operation can be set
by the FPU. The horn alert port is enabled or disabled as
follows;

■ 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.

■ 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 a 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 transmission.

■ 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.

■ Continuous
Horn alert can be reset by setting an expiration time from
the FPU, pressing the AUX-A key, or setting off hook.

■ 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.

TK-880/H
OPERATING FEATURES
4-2. Trunking Format
■ 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.

■ 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.

■ Auto TEL
■ 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).

■ 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.

10

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 ( ) to indicate that this
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
It 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 fot the data communication period.

4-3. Conventional Format
■ “TOT” pre-alert
The transceiver has “TOT” pre-alert timer. This parameter selects the time at which the transceiver generates
“TOT” pre-alert tone before “TOT” is expired.
“TOT” will be expired when the selected time passes
from a TOT pre-alert tone.

■ “TOT” re-key time
The transceiver has “TOT” re-key timer. This timer is the
time you can not transmit after “TOT” exceeded. After
“TOT” re-key time expired you can transmit again.

TK-880/H
OPERATING FEATURES
■ “TOT” reset time
The transceiver has “TOT” reset timer. This timer is the
minimum wait time allowed during a transmission that will
reset the “TOT” count.
“TOT” reset time causes the “TOT” to continue even
after PTT is released unless the “TOT” reset timer has expired.

■ OST (Operator Selectable Tone)

With OR set up, alert/transpond will not function with
only DTMF (Trunking format).
With OR set up, AF mute will not release when only
DTMF matches.
With a conventional channel not set up with QT or DQT,
only the carrier is considered when signalling matches.

■ Auto Reset

The transceiver is capable to have “OST” function and 16
tone pair (QT/DQT) with max 10-digit name for each tone
pair.

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.

■ “OST” back up

■ Dead Beat Disable

The transceiver is programmable the selected “OST”
code is memorized or not. If you set to Disable (no memorized), the “OST” function always starts at “off”.

■ Direct “OST”
It is possible to call “OST” number directory using keypad. In this case, keypad is used for “OST”, then auto
“PTT” store and send functions by keypad are not usable.

■ Clear to transpond
The transceiver waits the transpond of 2-tone /DTMF if
channel is busy until channel open. This feature prevents
the interference to other party.

5. Option Signalling
5-1. DTMF/2-Tone
Built-in DTMF decoder is available for option signalling.
Built-in 2-tone 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/channel which is
set up with option signalling, the option signalling indicator
( ) will 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
conditions.
Alert/Transpond
AND

QT/DQT/ID+DTMF (2-tone); Option matches = Action

OR

QT/DQT/ID+DTMF (2-tone); Option matches = Action
AF mute open

AND

QT/DQT/ID+DTMF (2-tone); Option matches = Action

OR

QT/DQT/ID; Signalling only matches = Action

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 channel, 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.

5-2. MSK
Built-in MSK (FleetSync™ : Fleet-ID) decoder is available
for option signalling. When the group ID/Carrier matches,
squelch remains muted while the station waits for reception
of proper MSK signal. When MSK signal matches, squelch
unmutes.

■ AND/OR
AND : QT/DQT/ID + MSK to unmute. MSK matches =
alert tone
OR : QT/DQT/ID to unmute. MSK matches = alert tone

6. 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 the specific Fleet user the same as selective call.

11

TK-880/H
OPERATING FEATURES
■ Selective Call (SELCALL)

• Automatic status response

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

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).)

• Example of call types;
[100][ALL ] : 
All the units whose fleet number is “100” are called.
[100][1000] : 
The unit, whose the fleet number is “100” and ID number is “1000”, is called.
[ALL][ALL ] : 
All the units are called.
[ALL][1000] : 
All ID “1000” are called regardless of their fleet number.

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".

• Unit ID encode block

■ 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.

■ Status Message

■ Emergency Function

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.

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

• 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;

ANMEA-0183 GPS unit must be installed.

Auto : GPS data is sent both automatically and by request. GPS Auto TX Interval and GPS Time Mark must be
adjusted if required.
Poll : GPS data is sent upon request from dispatcher.

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 report interval
Interval time between automatic GPS data transmissions.

• 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

• To start the Firmware Programmer from KPG-49D, the
FPRO path must be set up by KPG-49D setup.
• This mode cannot be entered if the Firmware programming mode is set to Disable in the Programming software (KPG-49D).
• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk before update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.

6-4. Function
1. If you press the [MON] switch while “PROG 57600” is
displayed, the checksum is displayed. If you press the
[MON] switch again while the checksum is displayed,
“PROG 57600” is redisplayed.
2. If you press the [D] switch while “PROG 57600” is displayed, the display changes to “PROG 19200” to indicate
that the write speed is low speed (19200 bps). If you
press the [D] switch again while “PROG 19200” is displayed, the display changes to “PROG 38400”, and the
write speed becomes the middle speed (38400 bps). If
you press the [D] switch again while “PROG 38400” is
displayed, the display returns to “PROG 57600”.

How to enter the password with the [System up/down]
key (Trunking format), the [Group up/down] key (Conventional format);
If the [System up/down] key (Trunking format), the
[Group up/down] key (Conventional format) 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.
Power on the slave TK-880/880H.
Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.
Press the [S] 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.
The other slave can be continuously cloned. When the
[S] 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.

Note :
Only the same models can be cloned together.

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 TK-880/880H power ON with the [C] key
held down. If the password is set to the TK-880/880H,
the TK-880/880H displays “CLONE LOCK”. If the password is not set, the TK-880/880H displays “CLONE
MODE”.
2. When “CLONE LOCK” is displayed, only the [System up/
down] key (Trunking format), the [Group up/down] key
(Conventional format) and [SCN], and [0] to [9] keys can
be accepted. When you enter the correct password, and
“CLONE MODE” is displayed, the TK-880/880H 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 TK-880/
880H. 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.

TK-880/H
CIRCUIT DESCRIPTION
with the first local signal by IC200, then converted to the
first IF signal of 44.85MHz. The first local signal passes
through an LPF and an attenuator to eliminate unwanted
harmonics components and implement the optimum input
level to the mixer, then enters IC200. A DBM is used as a
mixer to achieve a high potential.
The signal output from the mixer is amplified by an intermediate frequency amplifier and input to two MCFs (XF1).
The signal is amplified by another intermediate amplifier and
goes to the FM IF IC (IC11). The first intermediate frequency signal is mixed with the second local signal of
44.395MHz to produce the second IF signal of 455kHz.
The unwanted near-by signal components are then eliminated by a wide ceramic filter (CF1) or a narrow ceramic filter (CF2) and the resulting signal goes back to the FM IF IC.
The signal is quadrature-detected in the IC to produce an
audio signal, which is amplified by a DET amplifier (IC2) and
output to the TX-RX unit (B/2).

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 5, 6.25kHz 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 TX-RX unit (A/2) contains a wide/narrow MCF
and CFs. The transmit signal is produced by the PLL circuit
for direction oscillation and division. The signal output from
the VCO is amplified by a straight amplifier and transmitted.

■ Wide/Narrow Changeover Circuit
The W/N port (pin 11) of the shift register (IC7) is used to
switch between ceramic filters. When the W/N port is high,
Q24 turns on and the ceramic filter SW diode (D22, D23)
CF1 turns on to receive a Wide signal. At the same time,
Q16 turns on and one of the filters is selected so that the
wide and narrow audio output levels are equal.
When the W/N port is low, Q23 turns on and the ceramic
filter SW diode (D22, D23) CF2 turns on to receive a Narrow
signal.

resonators and eight varicap diodes (K3,HK3 : D203~D206,
D212~D215, K,K2,HK,HK2 : D203~D206) to eliminate unwanted out-of-band signal components. The low-noise amplifier (LNA) (Q201) uses a bipolar transistor to achieve wideband and low-distortion amplification.

CIRCUIT DESCRIPTION
■ 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.

Transmitter System
■ Outline
The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the carrier signal
by means of a varicap diode.

■ VCO/PLL Circuit
The TK-880/880H has a VCO for the transmitter and a
VCO for the receiver in a sub-unit (A1). They are housed in a
solid shielded case and connected to the TX-RX unit (A/2)
through CN101. One of the VCOs is selected with an ST
signal. A filtered low-noise power supply is used for the
VCOs and varicap diodes.
The VCO for the transmitter is described below. It is designed so that Q103 turns on with a prescribed frequency
when a reverse bias is applied to D102 and D104 by using
the control voltage (CV) through CN101. The control voltage
is changed by turning the trimmer capacitor (TC109). The
output from Q103 is applied to the buffer amplifier (Q106) 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 Q106 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
D105 and passes through C112 and C113 to modulate the
carrier.
The PLL IC uses a fractional N type synthesizer to improve 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, 2.5ppm
(–30 to +60°C) and guarantees stable performance when
the temperature changes. The output signal from the phase
comparator passes through a charge pump in the PLL IC and
an external active LPF (Q301, Q302) 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.

CIRCUIT DESCRIPTION
■ Unlock Circuit
During reception, the TR signal goes high, the KEY signal
goes low, and Q10 turns on. Q11 turns on and a voltage is
applied to the collector (8R). During transmission, the TR
signal goes low, the KEY signal 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 signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this
signal and makes the KEY signal low. When the KEY signal
goes low, no voltage is applied to 8T, and no signal is transmitted.

The APC circuit is configured to protect overcurrent of
the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage
and temperature variations.

Control Circuit
The CPU carries out the following tasks:
1) Controls the shift register (IC7, IC8, IC508) AF MUTE,
WIDE/NARROW, T/R KEY outputs.
2) Adjusts the AF signal level of the audio processor (IC504)
and turns the filter select compounder on or off.

■ 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
Q513 turns on, and the key illumination LED lights. A voltage is applied to the LEDA line to turn on the LCD backlight.

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.

■ Key Matrix Circuit
The TK-880/880H 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.

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).

■ 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).

■ 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)

CIRCUIT DESCRIPTION
■ 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.

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 20 V 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.

• 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

■ Note
• Flash memory
The firmware program (User mode, Test mode, Tuning
mode, etc.) and the data programmed by the FPU (KPG-49D)
for the flash memory, is stored in memory. When parts are
changed, program the data again.

Repair Jig (Chassis)

• EEPROM

Use jig (Part No. : A10-4010-02) for repairing the TK-880/
880H. The jig facilitates the voltage check when the voltage
on the component side TX-RX unit (A/2) is checked during
repairs.

The tuning data (Deviation, Squelch, etc.) for the
EEPROM, is stored in memory. When parts are changed,
readjust the transceiver.
