SelectiveCommunication
Many repeaters require a CTCSS tone or a DCS encode setting as a “key” to access a repeater system, or a
receiver using CTCSS or DCS squelch, so called “selective-calling”. Sometimes, CTCSS or DCS decode
features are used on the output of a repeater so they can be used to open a squelch. In this mode,
regardless of the main squelch status, the audio can be heard ONLY when the matching tone/code signal is
received. The combination of CTCSS squelch and DCS function is not available; only one or the other may
be used for given frequency.
CTCSSencoding,Tone-squelchandDCSoperations
1. In the VFO mode, set the operating band
to MAIN. Press the FUNC key then press
 key while [FUNC] appears on the
display.
The current tone frequency will be
displayed. Repeat pressing  key to
select the setting mode as below:
[T] CTCSS encoding: Transmits CTCSS
encoding tone for repeater accesses.
[T][SQL] CTCSS encoding and decoding
tones. Tone squelch operation is
possible.
[DCS] DCS operation is possible. In DCS,
both encoding and decoding tones are
the same.
Press any key except  key to complete
and return to operating mode. T/TSQL/
DCS icons remains displayed.
The same operation is possible in the memory mode
but temporary. Channel and power operation will delete
setting.
2. In above [T] , use Dial or UP/DOWN keys
to select tone-encoding frequency. This
value will apply automatically to the next
decoding tone. In [TSQL], operating dial
or UP/DOWN keys select the decoding
frequency only. This is for a special
application and conventional repeaters
don’t require to separate encoding and
decoding tones.
