Sending a group call
A group MMSI is a shared MMSI. When a DSC call is transmitted by
one of the vessels in the group, all the radios that have the same
MMSI entered will receive the message, and can reply on the chosen
channel if necessary.
To enter a group MMSI, see "Creating a group MMSI" on page 96.
¼ Notes:
•
Unlike the DSC or ATIS MMSI, a group MMSI can be changed at any
time.

Group calls are always sent with ROUTINE priority.
