Raymarine Ray73 VHF radio is communications central for your boat with built-in VHF, AIS and public-address capabilities. Built on Raymarine's full-sized marine radio chassis, the radio comes with oversized controls and a big screen for easy operation offshore.

This is a full-function VHF marine radio with Class D Digital Selective Calling (DSC) and a built-in GPS receiver. Simply program your boat's MMSI number into the Ray73 and immediately benefit from the enhanced calling and safety features of DSC. The Ray73 supports both NMEA2000 and legacy NMEA0183 networking, which enables connection to other onboard electronics. Ray73 also supports the connection of an optional remote speaker (A80542) to provide audio at a second location.

Includes a built-in loud-hailer output. Add the optional hailing horn (M95435) and use your Ray73 to communicate with crew members on deck, on the dock, or on another boat. It can also generate manual or automatic fog signals with built-in tone and gong sounds that comply with all international regulations.

Supports dual control stations with the addition of the optional RayMic second station kit. With an oversized LCD and simple controls, the RayMic is a compact all-in-one handset that fits easily on any secondary helm, tower or navigation station. Use RayMic for station-to-station intercom capability too.

Designed to comply with the latest international regulations and includes a connection point for an optional GPS/GNSS antenna system. The optional antenna improves the GPS reception when the radio is mounted below deck, in an enclosed pilothouse, or inside a metal enclosure. An attractive industrial design that complements Raymarine's Axiom family multifunction displays. The radio includes both a standard trunnion mounting kit as well as surface mounting hardware.
