The GX2100 Matrix integrates a dual-channel AIS receiver that displays received AIS target vessels directly on your VHF radio. It displays AIS target information (MMSI, call sign, ship's name, BRG, DST, SOG, and COG) and will allow you to contact an AIS ship directly using DSC, show your position in relation to targets, and alert you when an AIS ship is approaching with its CPA (closest point of approach alarm). One antenna input is all that's needed since the GX2100 utilizes the VHF antenna to receive targets from ships with AIS class A or B transponders. Features an 80 db commercial-grade receiver with local/distance attenuator, Class D DSC, and powerful 30-watt loud hailer with preprogrammed fog signals. Radio has durable chassis, user-changeable channel names, optional voice scrambler, noise-canceling speaker microphone, 4.5-watt audio output, NOAA weather alert, and programmable scan. The GX2100 Matrix allows you to enter up to 100 waypoints and navigate to them with a unique navigation compass; display shows your vessel SOG, COG, BRG, and DST to the waypoint. Radio can be connected to a RAM3 Remote Access microphone, allowing control of all VHF, DSC, and hailer functions remotely. Features the ability to poll the GPS location of another vessel and show that vessel's position on the radio's alphanumeric display. Meets JIS7 submersible standards. Three-year warranty.
