GPSrChive Group Ride Radio - CTCSS Radio Frequencies

CTCSS Frequencies

CTCSS is an acronym for Continuous Tone Controlled Squelch System.
With CTCSS enabled, a continous sub-audible tone is transmitted at the selected frequency.
Squelch tones allow you to filter calls from other users on the same channel, so you hear only the radios you want to hear.
Squelch tones do not make your conversation private (anyone on the same channel can still hear your conversation).
Calls on the same channel that are not using the same squelch tone will be ignored.
The Group Ride Radio can be configured to use the following CTCSS squelch tones:
