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

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.
