Ray73 VHF radio with integrated GPS and AIS receiver

The main difference is that the Ray73 integrates an AIS receiver in addition to the GPS. This allows you to receive the positions of other vessels and display them on a compatible multifunction display. The Ray63, on the other hand, only has GPS functionality.

No, the Ray73 VHF is equipped with an AIS receiver (AIS Rx) only. It receives data from other vessels equipped with an AIS transmitter to anticipate collisions, but does not broadcast your own position over the AIS network.

Yes, the Ray73 has a dedicated 25W (at 4 ohms) or 12W (at 8 ohms) audio output to connect a deck speaker (hailing port). This function allows communication with the crew and automatic fog signal generation.

Yes, the Ray73 VHF’s front panel is waterproof certified to IPX6 (powerful water jets) and IPX7 (temporary immersion) standards, making it fully suited to marine environments and spray.

The Ray73 VHF operates on a 12V DC electrical system. Its operating voltage range is from 9V to 16V DC, with built-in overvoltage protection.

The Ray73 has an integrated GNSS (GPS) receiver with its own internal antenna. However, if the VHF is installed inside a metal cabin or under a deck blocking the signal, it is possible to connect an external passive GPS antenna (such as part number A80288).

To overlay AIS targets on your multifunction display, you must connect the Ray73 VHF to your chartplotter via the NMEA2000 (SeaTalk NG) or NMEA0183 network.

Absolutely. The Ray73 is scalable and allows the addition of a second wired station (RayMic combined unit) or a wireless hub to use wireless combined units. It is an ideal solution for having total control from a flybridge or cockpit.

The Ray73 VHF is compatible with NMEA2000 (via SeaTalk NG connectivity) and NMEA0183 communication protocols. This ensures excellent integration with most onboard electronic equipment.

It is recommended to install the VHF at least 1 meter away from any other equipment transmitting radio signals or their cables, and more than 2 meters from a radar beam to avoid electromagnetic interference.

Yes, the product includes a SeaTalk NG 400 mm spur cable to facilitate connection to your boat's NMEA 2000 network.

Yes, the Ray73 VHF allows connection of an external passive speaker for clearer reception of communications. The dedicated output power for this external speaker is 5W at 8 ohms.

Yes, the Ray73 is a VHF radio equipped with Digital Selective Calling (DSC) Class D. It allows you to send automated distress signals containing your exact GPS position to rescue services and nearby vessels.

The software update is typically performed via a compatible Raymarine multifunction display (such as an Axiom) connected to the same SeaTalk NG network. It is critical to maintain stable power supply throughout the entire update process.

Yes, the Ray73 VHF offers great installation flexibility. It can be mounted on its supplied bracket or flush-mounted directly in a console or dashboard. A mounting template is available to simplify cutting.

The Ray73 VHF offers two transmit power modes: a high-power mode at 25 Watts for maximum range, and a low-power mode at 1 Watt for short-range communications or harbour use.

Yes, it is fully compatible with the entire Axiom range (Axiom, Axiom Pro, Axiom XL) as well as with the older eS, gS, aSeries, and cSeries via the SeaTalk NG network.

Use only a clean, damp cloth to wipe the device. Never use abrasive products, acids, ammonia-based cleaners, or chemical solvents that could damage the seal and the screen.

Yes, the Ray73 VHF allows private channel configuration if your local navigation regulations permit it. This requires intervention by an authorized dealer or installer.

No, the built-in AIS receiver uses the same VHF antenna as the radio to receive signals. Therefore, it is not necessary to install a second VHF antenna or an external splitter, which greatly simplifies installation.
