9.6 GROUP
CALL
This feature allows the user to contact a group of specific vessels (e.g.
members of a yacht club) using DSC radios with group call function to auto-
matically switch to a desired channel for voice communications. This func-
tion is very useful for yacht clubs and vessels traveling together that want
to collectively make announcements on a predetermined channel. Up to 32
group MMSI (Maritime Mobile Service Identity Number) may be programmed.
9.6.1 Setting up the Group Call
For this function to operate, the same group MMSI must be programmed
into all the DSC VHF radios within the group of vessels that will be using this

The USCG recommends programming the MID of a ships MMSI into the
second, third and fourth digits of the group MMSI as it denotes the area
the ship is located in.
The last 5 digits are decided upon by persons in the group. This is an
important step as all radios in the group must contain the same group
MMSI so they can be contacted by each other. There is a chance that
another group of vessels may program in the same group MMSI. If this
happens, simply change one or more of the last 5 digits of the group
MMSI.
