I have a Ray215, I can transmit and receive but I can no longer adjust the squelch. I get no audio when trying to set the squelch. Any ideas?
Welcome to the Raymarine Forum FDNY357,
The symptom described would be indicative of a failure of the Ray215's squelch circuitry. Unfortunately, Raymarine can no longer service Ray215 VHF radios, necessitating its replacement. VHF radios of this class would typically be replaced with a Ray60 or Ray70 VHF radio (the latter combines VHF and loudhailer features within a single device).
