CTCss CoDes
CTCSS (Continuous Tone Coded Squelch System) is a Squelch
quieting system that allows several groups of users to share the
same channel without disturbing each other. The system applies a
continuous low‑level tone to your transmission and uses a matching
tone decoder in your receiver to control its Squelch. With CTCSS
enabled, the channel remains quiet to all incoming signals unless
they carry the correct tone. When a transmission with the correct
tone is received, the Squelch opens and remains open for as long
as the signal is present. When the transmission ends, the channel
becomes quiet again. Transmissions that do not use the correct tone
will not be heard.
The TX655 is fitted with 38 different CTCSS codes (see code chart).
You can select or change the current CTCSS code via the MODE
Menu. If the other radios you are communicating with are not using
CTCSS, set your CTCSS code to ‘oF’. The TX655 allows CTCSS to be
enabled or disabled on individual channels.
