Making DSC Calls

There are essentially four different types of DSC voice calls:

Call type	What it does	When to use it
Distress	Alerts all stations that you need assistance	In an emergency only.
	and sends them your current position.
Individual	Calls a single station using the User MMSL.	When you want to talk to another
		station.
Group	Calls all the stations that have the same	Any time you want with the whole
	Group MMSL as yours.	group you are traveling with at the
		same time.
All Ships	Calls all stations within range of your radio.	Safety warnings (e.g., debris in the
		water) or any urgent situation.

Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct all the racers to enter your group MMSI number into their radios. During the race:

xx Throughout the race, you use group calling to update the racers on the time, race status, and any course corrections.

xx A power boat full of spectators comes too close to the race path. You use individual calling to contact the power boat and advise them to stay clear of the race.

xx You see a rowboat entering the area, but since it doesn’t have a radio, you can’t communicate with the rowboat. You use all ships calling to alert all the other boats in the area of the possible danger.
