Digital Selective Calling (DSC) is a standard that allows you to call other stations using their

What is DsC?

unique identification code (the Maritime Mobile Service Identity or MMSI number), just
like you would call a phone number. To call another station, just enter that station's MMSI
number and choose the voice channel you want to talk on. The radio uses channel 70 to
transmit your MMSI number to the other station along with the voice channel you requested.
If the other station accepts your call, both radios automatically switch to the requested voice
channel so you can talk to the other station.
DSC provides a system for automated distress calls. At the touch of a button, the radio can
transmit your MMSI number, the nature of your distress, and your current position based
on data from your GPS receiver. The radio repeats the distress call every few minutes until it
receives an acknowledgement.
The DSC standard dedicates a VHF channel—channel 70—to digital transmissions only. Since
digital transmissions require less bandwidth voice transmissions, channel 70 avoids the
problems of busy voice channels.
