What is DSC?
Digital Selective Calling (DSC) is a global protocol that uses channel 70 (156.525
MHz) to transmit and receive digital messages. It works on DSC equipped VHF
radios and is used for individual, ‘all ships’ and distress calls. DSC also enables
you to selectively alert single or multiple boaters of incoming VHF calls by using
stored MMSI (Maritime Mobile Service Identification) numbers, similar to making
a phone call.
You can also poll another boat to obtain its GPS position and display it on a
Raymarine multifunction display.
DSC safety digital Mayday.
If you are unfortunate enough to find yourself having to make a mayday call, the
last thing you need is extra complication. Making a DSC distress call is simple
with Raymarine’s DSC equipped VHFs. Just press the button, clearly marked in
the back of the handset, and GPS position and time information are transmitted
in a digital ‘packet’ complete with the vessel’s Maritime Mobile Service
Identification (MMSI) telling other ships and shore stations exactly where you are
and that you are in a distress situation. This simple procedure can dramatically
increase your chance of a successful rescue compared to a traditional Mayday
voice call.
