Product Description
Fixed Mount Marine VHF Two-Way Radio of GMDSS System
VHF radio installation is an important part of GMDSS system. There devided into Class A & Class D acccording to the DSC mode.
Class A is for use on commercial ships. Class A sets have all the bells and whistles, including a second antenna and receiver to provide continuous DSC monitoring.
Class D is for recreational vessels. Class D sets have the same core functionality as Class A sets, including a dedicated DSC receiver, but with some limitations:
- They usually cannot transmit group, geographic area or "mayday relay" messages over DSC.
- They have only one antenna, so most of them cannot receive DSC messages while transmitting.
- They are simplex only (one person talks at a time, like a walkie-talkie), with no duplex (telephone-like) mode.
VOICE and DSC used to make the following kinds of calls:
1. Distress
2. Emergency and Safe Commnunication
3. Requirements of Ship Maneuvering
4. Public Service Communication
