VHF radio installation is an important part of GMDSS system. Voice and DSC are used to make the following
kinds of calls: distress, emergency and safe communication, requirements of ship maneuvering, public
service communication.
VHFCH70 DSC automatic watching.
The distress alarm is activated by special distress button, and DSC alarm information is transmitted in CH70
special channel. Seek rescue by sending alarm information to surrounding ships and shore stations
In the rescue field, as a rescue ship or rescued ship to communicate with each unit, it has the function of one
key to switch CH16.
