Digital Selective Calling (DSC)
•
Digital selective calling is a semi-automated system for establishing a radio call. It
has been designed by the International Maritime Organization (IMO) as an international
standard for VHF, MF, and HF calls and is part of the Global Maritime Distress and
Safety System (GMDSS).
DSC will eventually replace aural (listening) watches on distress frequencies and will
be used to announce routine and urgent maritime safety information broadcasts. Until
DSC is fully implemented, it is still necessary to maintain a listening watch on Channel
16.
The DSC system allows mariners to instantly send a distress call with GPS position
coordinates to the Coast Guard and other vessels within range of the transmission. DSC
also allows mariners to initiate and receive distress, urgent, safety, routine, position
request, position send, and group calls between vessels equipped with DSC capable
radios.

An MMSI is a nine (9) digit number used on a marine radio capable of using digital
selective calling (DSC). It is used to selectively call other vessels or shore stations and
is similar to a telephone number.
For your CobraMarine

radio to operate in the
DSC
mode, you must enter your maritime
mobile service identity (MMSI) number. See page 55 for instructions
on how to enter it.
