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