Desktop VHF Radio
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. 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 is also used for daily communication on board.
