Learn morePremium VHF with a built-in AIS receiver and loudhailer. Remote station capable, with wired and wireless microphone options
Raymarine’s Ray73 VHF radio features an internal AIS receiver and loudhailer capabilities. Built on our marine radio chassis, the Ray73 comes with oversized controls and a big screen for easy operation offshore. The Ray73 also supports optional wired or wireless RayMic controllers for true multi-station control and intercom capability. When connected to an optional hailing horn, the Ray73 can generate automatic fog signals and work as a public address announcement system.
