3.7 Group Call
A Group call allows the user to contact a group of specific vessels (example members
of a yacht club) using DSC radios that have a Group call function. When a Group call
is sent, all DSC radios in the group automatically switch to the channel specified in the
call to prepare for voice communications. This function is useful for yacht clubs and
vessels traveling together that want to collectively make announcements on a prede-
termined channel. Up to 32 Group call MMSIs can be programmed.
3.7.1 How to register DSC stations to the Group Directory
For this function to operate, the same Group call MMSI must be registered into all the
DSC VHF radios within the group of vessels that use this feature. To understand
Group call MMSI programming, first a ship MMSI has to be understood.
Ship MMSI: The first three digits are called an MID (Maritime Identification Digits) and
identify the country where the ship’s MMSI is registered. The last six digits are specific
to the ship’s ID. For example, if the MMSI is "366123456", "366" is the MID and
"123456" is the ship’s MMSI.
