OPERATING FEATURES  
3) Scan Stop Condition  
6 Selected with talkback  
The scan stops temporarily if the following conditions are  
satisfied.  
The transceiver reverts to the channel before scanning or  
the channel that you changed during scan.  
1 The receiving signal matches the signalling code in your  
radio that is set by the programming software (KPG-56D).  
2 When the Monitor key is depressed.  
8) Scan End  
When you reactivate the key programmed to the scan  
function during scan mode, scan ends.  
The scan icon ("SCN") and "SCAN" or revert channel  
(programmable) display goes off.  
4) Scan Channel Types  
1 Priority channel is the most important channel for scan,  
and always detects a signal during scan and when the scan  
stops temporarily.  
9) Temporarily Delete/Add  
2 Non-priority channels detect a signal during scan. For the  
channels that can be selected with the group or channel  
selector when the scan does not occur, the "A" icon lights.  
It is possible to delete or add a channel temporarily during  
scan. When scan stops on an unnecessary channel, for  
example by interference of the other party, press the delete/  
add key, then that channel is deleted temporarily and scan will  
re-start immediately.  
5) Priority Channel Setting  
A priority channel can be set as follows with the programming  
software (KPG-56D).  
1 Specify a priority channel as a fixed priority channel.  
2 Make a selected channel a priority channel.  
Specify the initial channel before the operator changes it.  
When you would like to add a deleted channel temporarily  
to the scan sequence, select the desired (deleted) channel  
during scan, and press the delete/add key before scan re-starts.  
That channel is added temporarily to the scan sequence.  
The temporarily deleted or added channels are returned to  
their pre-set delete/add conditions when the transceiver exits  
from scan mode.  
6) 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.  
5. Details of Features  
1) Time-out timer  
The time-out timer can be programmed in 15 seconds  
increments from 15 seconds to 300. 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.  
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.  
2) Selective Call Alert LED  
7) Revert Channel  
You can select whether or not the LED on the transceiver  
flashes orange when selective call has occurred.  
3) PTT ID  
The revert channel is used to transmit during scanning and  
set by the programming software (KPG-56D).  
1 Priority  
PTT ID provides a DTMF ANI to be sent with the PTT button  
every time it is used (Begin of TX ID at beginning of  
transmission, End of TX ID at end of transmission, or both).  
You can program the PTT ID as one of the followings.  
Off, BOT (Begin of TX ID), EOT (End of PTT ID), BOTH.  
The contents of ID are programmed for each channel.  
The transceiver is capable of having ID. The format is DTMF.  
The timing that the transceiver sends the ID is  
programmable.  
Begin of TX ID (BOT) : Begin of TX ID is sent at the  
beginning of transmission.  
End of TX ID (EOT) : End of TX ID is sent at the end of  
transmission.  
The transceiver reverts to the priority channel.  
2 Priority with 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 the current  
channel to answer to the call however revert channel is set  
to priority channel.  
After resume time, scan re-starts and the transmission  
channel returns to the 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  
scan.  
5 Last used channel  
Both : Begin of TX ID is sent at the beginning of transmission  
and End of TX ID is sent at the end of transmission.  
There is also a "PTT ID" setting for each channel.  
The transceiver reverts to the last used (transmitted)  
channel during scan. "Last used" revert channel includes  
talkback function.

TK-260G/270G  
OPERATING FEATURES  
4) Battery Warning  
6. Option Signalling (DTMF/2 tone)  
This transceiver has a battery warning feature. If low voltage  
is detected during transmission, the transceiver warns you by  
a flashing red "LED".  
Built-in DTMF decoder is available for option signalling.  
Built-in 2-Tone decoder is available for option signalling.  
When the voltage is detected to be even lower during  
transmission, the transceiver stops transmission and warns  
you by a flashing red "LED" and a beep.  
It is possible to use individual call, group call, DBD (Dead  
Beat Disable). Note : DBD is only DTMF  
Please notice "indication" for the battery exchange, charging  
time by flashing red LED and beep.  
Preset operation is triggered when there is a match with  
Option Signaling.  
When Option Signaling matches on a Group Channel  
where it is set to Yes, the Option Signaling display flashes  
and Option Signaling is canceled. Settings after this will cause  
"Transpond" or "Alert" to sound.  
Setting the Selective Call Alert LED will cause the LED to  
start flashing orange.  
Mute or Unmute is triggered by the ID/QT/DQT/Carrier  
when option signaling matches (when Option Signal is  
deactivated by a transmission).  
5) "TOT" Pre-Alert  
The transceiver has a "TOT" pre-alert timer. This parameter  
selects the time at which the transceiver generates a "TOT"  
pre-alert tone before the "TOT" is expired.  
"TOT" will expire when the selected time passes from the  
TOT pre-alert tone.  
6) "TOT" Re-Key Time  
The transceiver has a "TOT" re-key timer. This timer is the  
time you cannot transmit after the "TOT" is exceeded. After  
the "TOT" re-key time expires you can transmit again.  
AND/OR  
Option Signaling match conditions can be selected with  
AND/OR logic.  
7) "TOT" Reset Time  
The transceiver has a "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  
the PTT is released, unless the "TOT" reset timer has expired.

a match just by receiving the carrier.  
only)  
The transceiver is capable of having the "OST" function  
and 16 tone pairs (QT/DQT) with a max 10-digit name for each  
tone pair.  
9) Clear to Transpond  
The transceiver waits for an acknowledment signal until the  
channel free.  
Auto Reset  
When Option Signaling matches on a Group channel where  
it is set to Yes, Option Signaling is canceled when it matches a  
group channel set to Yes.  
This feature ensures the acknowledment signal is receive  
by another party.  
After Option Signaling matches, Option Signaling can  
automatically Reset after a specified time.  
10) Battery Save  
This is the automatic battery saver during standby mode  
operation. The receiver circuit is turned on and off to conserve  
the battery life.  
Dead Beat Disable  
When the D.B.D (Dead Beat Disable) code matches, a  
preset operation is performed.  
When D.B.D matches on all group channels regardless of  
whether Option Signaling = Yes/No, then TX Inhibit or TX RX  
Inhibit is activated by the settings performed afterwards. D.B.D  
is canceled when the D.B.D. code + "#" is received.  
Transpond is always activated when the D.B.D code  
matches. Alert is not output. An Option Signaling match is not  
displayed.

6-1. Preface  
Flash memory is mounted on the TK-260G/270G. This  
allows the TK-260G/270G to be upgraded when new features  
are released in the future. (For details on how to obtain the  
firmware, contact Customer Service.)  
the interface cable.  
2. When the POWER is switched on, user mode can be  
entered immediately. When the PC sends a command,  
the radio enters PC mode.  
When data is transmitted from transceiver, the red LED  
blinks.  
When data is received by the transceiver, the green LED  
blinks.  
6-2. Connection procedure  
Connect the TK-260G/270G to the personal computer (IBM  
PC or compatible) with the interface cable (KPG-22).  
(Connection is the same as in the PC Mode.)  
Notes:  
•
The data stored in the personal computer must match the  
model type when it is written into the flash memory.  
Change the TK-260G/270G to PC mode, then attach the  
interface cable.  
6-3. Programming  
1. Start up the programming software (KPG-56D), select  
"firmware program" in the "Program" item, and press the  
Return key on your personal computer. This starts up the  
firmware programmer.  
•
5-3. KPG-22 description  
2. The top screen is displayed. Press any key to advance to  
the next screen.  
3. Set the communications speed (normally, 57600 bps) and  
communications port in the Setup item.  
4. Set the firmware to be updated by File select (=F1).  
5. Hold down the [LAMP] and [MON] switches on the TK-260G/  
(PC programming interface cable: Option)  
The KPG-22 is required to interface the TK-260G/270G 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-22 connects the SP/MIC connector of the TK-  
260G/270G to the computers RS-232C serial port.  
270G, and press the power switch.  
5-4. Programming software description  
The KPG-56D programming disk is supplied in 3-1/2” disk  
format. The software on this disk allows a user to program  
the TK-260G/270G radios via a programming interface cable  
(KPG-22).  
When the [LAMP] and [MON] switches are held down for  
two seconds, "PROG576" appears on the display and  
the LED lights orange. When "PROG576" is displayed,  
release the switches (TK-270G only).  
6. Check the connection between the TK-260G/270G and  
the personal computer, and make sure the TK-260G/270G  
is in Program mode.  
7. Press F10 on the personal computer. A window opens on  
the display to indicate the writing progress. When the TK-  
260G/270G begins to receive data, the LED lights green.  
8. When data is received successfully, a checksum appears  
5-5. Programming with IBM PC  
If data is transferred to the transceiver from an IBM PC  
with the KPG-56D, 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.  
on the display.  
The values should be modified only if necessary. Data can  
be programmed into the flash memory in RS-232C format via  
the universal connector.  
(Since the TK-260G does not have a display, check the  
checksum with the FPU (KPG-56D).)

CIRCUIT DESCRIPTION  
3) IF Amplifier circuit  
1. Frequency configuration  
The first IF signal is passed through a four-pole monolithic  
crystal filter (XF1) to remove the adjacent channel signal.  
The filtered first IF signal is amplified by the first IF amplifier  
(Q22) and then applied to the lF system IC (IC4). The IF  
system IC provides a second mixer, second local oscillator,  
limiting amplifier, quadrature detector and RSSI (Received  
Signal Strength Indicator). The second mixer mixes the  
first IF signal with the 50.4MHz of the second local oscillator  
output (TCXO X3) and produces the second IF signal of  
450kHz.  
The second IF signal is passed through the ceramic filter  
(CF1; Wide, CF2 ; Narrow) to remove the adjacent channel  
signal. The filtered second IF signal is amplified by the  
limiting amplifier and demodulated by the quadrature  
detector with the ceramic discriminator (CD1). The  
demodulated signal is routed to the audio circuit.  
The receiver utilizes double conversion. The first IF is 49.95  
MHz and the second IF is 450 kHz. The first local oscillator  
signal is supplied form the PLL circuit.  
The PLL circuit in the transmitter generates the necessary  
frequencies. Fig. 1 shows the frequencies.

TK-260G/270G  
CIRCUIT DESCRIPTION  
(3) DTMF (High-speed data)  
5) Audio amplifier circuit  
The demodulated signal from IC4 is amplified by IC16 (2/  
2), high-pass filtered, low-pass filtered, high-pass filtered,  
band-eliminate filtered, and de-emphasized by IC14.  
The signal then goes through an AF amplifier IC15 (2/2),  
an AF volume control (VR2), and is routed to an audio  
power amplifier (IC11) where it is amplified and output to  
the speaker.  
The DTMF input signal from the IF IC(IC4) is amplified by  
IC16(2/2) and goes to IC18, the DTMF decoder. The decoded  
information is then processed by the CPU. During  
transmission and standby, the DTMF IC is set to the power  
down mode when the PD terminal is High. When the line is  
busy, the PD terminal becomes Low, the power down mode  
is canceled and decoding is carried out.  
6) Squelch  
3. PLL frequency synthesizer  
Part of the AF signal from the IC enters the FM IC (IC4)  
again, and the noise component is amplified and rectified  
by a filter and an amplifier to produce a DC voltage  
corresponding to the noise level.  
The PLL circuit generates the first local oscillator signal for  
reception and the RF signal for transmission.  
1) PLL  
The DC signal from the FM IC goes to the analog port of  
the microprocessor (IC13). IC13 determines whether to  
output sounds from the speaker by checking whether the  
input voltage is higher or lower than the preset value.  
To output sounds from the speaker, IC6 sends a high signal  
to the SP MUTE line and turns IC11 on through  
Q32,Q33,Q34 and Q30.(See Fig. 4)  
The frequency step of the PLL circuit is 5 or 6.25kHz.  
A 16.8MHz reference oscillator signal is divided at IC2 by a  
fixed counter to produce an oscillator (VCO) output signal which  
is buffer amplified by Q3 then divided in IC2 by a dual-module  
programmable counter. The divided signal is compared in  
phase with the 5 or 6.25kHz reference signal from the phase  
comparator in IC2. The output signal from the phase  
comparator is filtered through a low-pass filter and passed to  
the VCO to control the oscillator frequency.(See Fig. 5)  
7) Receive signaling  
(1) QT/DQT (Low-speed data)  
300Hz and higher audio frequencies of the output signal  
from IF IC are cut by a low-pass filter (IC19). The resulting  
signal enters the microprocessor (IC13). IC13 determines  
whether the QT or DQT matches the preset value, and  
controls the SP MUTE and the speaker output sounds  
according to the squelch results.  
2) VCO  
The operating frequency is generated by Q2 in transmit  
mode and Q10 in receive mode. The oscillator frequency is  
controlled by applying the VCO control voltage, obtained from  
the phase comparator, to the varactor diodes (D2 and D4 in  
transmit mode and D9 and D11 in receive mode). The T/R pin  
is set high in receive mode causing Q7 and Q8 to turn Q2 off  
and Q10 on.  
The T/R pin is set low in transmit mode. The outputs from  
Q10 and Q2 are amplified by Q3 and sent to the buffer  
amplifiers.  
(2) 2-TONE (High-speed data)  
Part of the received AF signal output from the AF amplifier  
IC16(2/2), and then passes through an audio processor  
(IC14), goes to the other AF amplifier IC15(1/2), is  
compared, and ther goes to IC13. IC13 checks whether 2-  
TONE data is necessary. If it matches, IC13 carries out a  
specified operation, such as turning the speaker on. (See  
Fig. 4)  
The outputs from Q3 to Q4 is divided into 1/2 in passing  
through a Divider IC (IC301), and goes to the RF amplifiers.

If a pulse signal appears at the LD pin of IC2, an unlock  
condition occurs, and the DC voltage obtained form D1,

to go low. When the microprocessor detects this condition,  
the transmitter is disabled, ignoring the push-to-talk switch  
input signal.(See Fig. 6)

3) APC circuit  
The APC circuit always monitors the current flowing through  
the RF power amplifier (IC1) and keeps a constant current.  
The voltage drop at R56, R57 and R58 is caused by the  
current flowing through the RF power amplifier and this  
voltage is applied to the differential amplifier IC3(1/2).  
IC3(2/2) compares the output voltage of IC3(1/2) with the  
reference voltage from IC13, and the output of IC3(2/2)  
controls the VGG of the RF power amplifier to make both  
voltages the same.

4. Transmitter System  
1) Microphone amplifier  
The signal from the microphone passes through the limitter  
circuit in D23, and through the high-pass filter, the ALC  
circuit, the low-pass filter, the high-pass filter, and pre-  
emphasis/IDC circuit IC14. When encoding DTMF, the mute  
switch (Q35) is turned OFF for muting the microphone input  
signal.  
The change of power high/low is carried out by the change  
of the reference voltage.  
The signal passes through the D/A converter (IC17) for the  
maximum deviation adjustment, and goes to the VCXO  
modulation input.

The signal from the T/R switch (D5 is on) is amplified by the  
drive amplifier (Q6) to 50mW.  
5. Power supply  
There are five 5V power supplies for the microprocessor:  
5V,5M,5C,5R, and 5T. 5V is always output while the power  
is on. 5M is always output, but turns off when the power is  
turned off to prevent malfunction of the microprocessor.  
5C is a common 5V and is output when SAVE is not set to  
OFF.  
The output of the drive amplifier is amplified by the RF power  
amplifier (IC1) to 5.0W (1W when the power is low). The  
RF power amplifier consists of two MOS FET stages. The  
output of the RF power amplifier is then passed through the  
harmonic filter (LPF) and antenna switch (D3 is on) and  
applied to the antenna terminal.  
5R is 5V for reception and output during reception.  
5T is 5V for transmission and output during transmission.

CIRCUIT DESCRIPTION  
3) Low battery warning  
6. Control Circuit  
The battery voltage is monitored by the microprocessor  
(IC13). When the battery voltage falls below the voltage set by  
the Low Battery Warning adjustment, the LED flashes red to  
notify the operator that it is time to replace the battery. If the  
battery voltage falls even more (approx. 5.8V), a beep sounds  
and transmission is stopped.  
The control circuit consists of a microprocessor (IC13) and  
its peripheral circuits. It controls the TX-RX unit and transfers  
data to and from the display unit. IC13 mainly performs the  
following:  
(1) Switching between transmission and reception by the  
PTT signal input.  
(2) Reading system, group, frequency, and program data  
from the memory circuit.  
(3) Sending frequency program data to the PLL.  
(4) Controlling squelch on/off by the DC voltage from the  
squelch circuit.  
Low battery warning  
Battery condition  
The red LED flashes during  
transmission.  
The battery voltage is low but  
the transceiver is still usable.  
The red LED flashes and a  
continuous beep sounds  
while PTT is pressed.  
The battery voltage is low and  
the transceiver is not able to  
make calls.  
(5) Controlling the audio mute circuit by the decode data input.  
(6) Transmitting tone and encode data.  
1) Frequency shift circuit  
7. Optional Board Terminal  
The microprocessor (IC13) operates at a clock of  
9.8304MHz. This oscillator has a circuit that shifts the  
frequency by BEAT SHIFT SW (Q31).  
Terminals for mounting the option board are provided at  
the bottom edge of the TX-RX unit. The table below shows the  
correspondence between the board and terminals.  
2) Memory circuit  
Optional Board Terminal Function (CN5)  
Memory circuit consists of the CPU (IC13) and a flash  
memory (IC12). A flash memory has a capacity of 2M bits  
that contains the transceiver control program for the CPU  
and data such as transceiver channels and operating  
features.  
This program can be easily written from an external device.  
Data, such as DTMF memorise and the operating status,  
are programmed into the EEPROM (IC10).
