66 COMMUNICATIONS

Marine Communications: Hear the difference

Dependable communications = peace of mind.

Raymarine's communications systems combine innovative state-of-

the-art technology with robust waterproof construction, designed to

withstand life at sea.

Our radios feature single or multi-station VHFs, Class D DSC (Digital

Selective Calling), SeaTalk and NMEA connectivity. Whether blue

water cruising or fishing inshore, Raymarine have what you need for

communication safety at sea.

What is DSC? Digital Selective Calling (DSC) is a global protocol

that uses channel 70 (156.525 MHz) to transmit and receive

digital messages. It works on DSC equipped VHF radios and is

used for individual, ‘all ships’ and distress calls. DSC VHF radio

users can digitally contact other DSC equipped vessels eliminating

unnecessary VHF radio traffic and improving efficiency of ship-to-ship

communication.

DSC safety digital Mayday. If you are unfortunate enough to find

yourself having to make a Mayday call, the last thing you need is extra

complication. Making a DSC distress call is simple with Raymarine’s

DSC equipped VHFs. Just press the clearly marked button and GPS

position and time information are transmitted in a digital ‘packet’

complete with the vessel’s Maritime Mobile Station Identifier (MMSI)

telling other ships and shore stations exactly where you are and that

you are in a distress situation. This simple procedure can dramatically

increase your chance of a successful rescue compared to a traditional

Mayday voice call.
