Description: ICOM M422 VHF has built-in DSC watch function monitors Ch 70 (DSC channel) activity, even while you are on another channel. In an emergency situation, a formatted distress call can be sent at the touch of a button.
DSC uses a unique ID (MMSI code) similar to a telephone number, allowing you to make contact with a specific boater or group of boaters in your area. A total of 100 address IDs can be stored with a 5-character name.
With an external GPS receiver, the position request and position report functions allow you to exchange ships position. The received position information can be plotted on a third party GPS or other navigation equipment which accepts NMEA data format. The polling (request/reply) function checks whether a specific ship is in the communication range.
