SELECTING THE CTCSS OR DCS TONE
Choosing which tone to use will probably be dependent on the
other radios you talk to. If you talk to others outside your group
who already use CTCSS or DCS tones you will need to select the
tone set that matches theirs. The TX3100 includes most of the
commonly used tone sets.
If the users you talk to don’t currently use CTCSS or DCS you can
make your own choice. There is no difference in performance
between the two tone sets.
NOTE: When selecting tones please refer to the CTCSS and
DCS Tone Charts on pages 22 – 23.
The CTCSS and DCS tones are stored in your radio in a sequential
table. The first table location is OFF. The next 50 locations are
CTCSS tones followed by 104 DCS tones.
OFF CTCSS 01 to CTCSS 50 DCS 01 to DCS 104
