Since 1st February 1999, marine radio communication has undergone fundamental change. Ships and an increasing number of coastguards and coast stations are ceasing to monitor traditional distress frequencies including channel 16. Under the Global Maritime Distress and Safety System (GMDSS), a fully automatic system has become operational. At the touch of a button a distress message with an accurate GPS position can be sent using Digital Selective Calling (DSC).

Everyday radio operation has also been improved. Watchkeeping on channel 16 will be consigned to history. If the shore or another vessel needs to communicate with you for any reason, an alarm will sound. You will no longer need to listen for voice calls.

The DSC3 is designed to be used with the VHF3 transceiver.
