Product Description

Fixed Mount Marine VHF Two-Way Radio of GMDSS  System

 

Product Description

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
