Ray73 VHF Radio with AIS Receiver (E70517)

The Raymarine Ray73 VHF Radio with AIS Receiver – E70517 is a premium fixed‑mount marine VHF communications station built for safety, navigation, and integration on coastal and offshore boats. It combines a 25 W Class D VHF radio with Digital Selective Calling (DSC), a built‑in AIS receiver, and an integrated GPS/GNSS receiver, delivering critical vessel‑to‑vessel and positional data for improved situational awareness. The Ray73 also supports optional wired or wireless RayMic handset stations, loudhailer/fog signalling functionality, and integrates seamlessly with onboard networks via NMEA 2000 and NMEA 0183 to share AIS and GPS data with chartplotters, radar, and other instruments.
