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 and sends them
your current position.
In an emergency only.
Individual
Calls a single station using the User MMSL.
Any time you want to talk to another station.
Group
Calls all the stations that have the same Group MMSL as
yours.
Any time you want with the whole 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:
• Throughout the race, you use group calling to update the racers on the time, race status, and any course corrections.
• A power boat full of spectators comes a little too close to the race path. You use individual calling to contact the power boat and
advise them to stay clear of the race.
• 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.
