This feature allows the user to contact a group of specific vessels (example members of a
yacht club) using DSC radios with Group call function to automatically switch to a desired
channel for voice communications.
19.6.0 Setting up a 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 feature. The group MMSI is
a 9 digit (first digit permanently set to “0”) number that will allow other radios to call your
vessel along with others to automatically switch to a working channel for voice
communications. This function is very useful for yacht clubs and vessels traveling together
that want to collectively make announcements on a predetermined channel.
