11.7 GROUP CALL
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 auto-
matically switch to a desired channel for voice communications.
11.7.1 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 fea-
ture. The group MMSI is a 9 digit (first digit permanently set to “0”) number that

useful for yacht clubs and vessels traveling together that want to collectively
