TX6200
38/50 TONE SET
Most GME radios use the GME-50 CTCSS
tone set comprising 50 CTCSS tones.
However some radios such as the GME
TX610, TX630 and TX650 use a CCIR-38
Tone Set comprising 38 tones.
The TX6200 allows switching between
the GME-50 and CCIR-38 Tone Sets to
provide compatibility when these models
are used together.
NOTE: This setting is only available when
CTCSS is enabled on the radio.
To toggle between the CCIR-38 and
GME-50 tone sets:
1. Turn the TX6200 OFF.
2. Press and hold the SQL key while
turning the TX6200 ON.
The display will show the selected
Tone Set for 5 seconds
i.e. CCIR -38 displays ‘CTC38’
GME-50 displays ‘CTC50’
Once selected, the setting remains
stored in the radio until toggled again.
CTC38/CTC50
Tone set compatibility
The CTC50 tone set comprises all 38
tones from the CTC38 tone set plus an
additional 12 tones. This means that
when switching from CTC50 to CTC38,
some of the tones will not be available.
If your selected CTC50 tone has an
equivalent CTC38 tone, the selected
frequency will be retained where possible
but the displayed tone number may
change. Where the selected CTCSS tone
doesn’t exist, the CTCSS tone will be set
to Off. See CTCSS TONE FREQUENCY
chart below for comparison.
