Operation As A Repeater; Ctcss Operation - Kenwood TH-78A Instruction Manual

3) The DTMF code appears on the display.
Note
Transmission continues until the whole code string is recalled, even if the PTT switch is released. You
cannot stop DTMF code transmission once it is initiated.

OPERATION AS A REPEATER

This transceiver is capable of operating as a repeater. The transceiver listens on both bands simultaneously. As
soon as a signal is received on one band, the other shifts from receive to transmit and re-transmits the incoming
signal.
Function setting
1) Select the operating frequencies and adjust the squelch controls to threshold.
2) Press the F key for longer than one second and then press the 0 key. The MHz dot(.) will flash. To return to the
normal function, perform step 2 again.
Notes
1 The Time-out Timer function will automatically set to 3 minutes mode.
2 Combinations of SHIFT and CTCSS can be used in the Repeater mode. DTSS and PAGING will
not work in this mode.
CAUTION
This equipment can be extremely susceptible to lightening strike damage or intermodulation distortion if
it is operated on mountain top locations.

CTCSS OPERATION

The CTCSS unit (TSU-7) is included only with models delivered to the United States and Canada. The CTCSS unit
(TSU-7) installation instruction are shown on page 49.
If the Continuous Tone Code Squelch System (CTCSS) function is activated, the transceiver will not open squelch until
it receives the proper PL tone (tone squelch).
Selecting Tone Frequencies
