How does DSC work on a VHF radio?
DSC allows the radio to transfer information digitally, not just by voice, and to instantly send a digital distress alert to the Coast Guard. Part of that alert is a nine-digit Maritime Mobile Service Identity (MMSI) number that identifies the boat.
What VHF channel does DSC use?
Channel 70
Channel 70 has been designated the VHF/DSC digital call channel. DSC technology allows boaters to send a digital call directly to other DSC-equipped vessels and shore stations, somewhat like a telephone call. Once the DSC call has been confirmed, both parties are automatically switched to a working voice channel.
How do I connect NMEA 0183 wires?
When wiring NMEA 0183 devices, follow these guidelines:
- Transmit (Tx) (+) should connect to a receive (Rx) (+)
- Tx (-) should connect to a Rx (-)
- Rx (+) should connect to a Tx (+)
- Rx (-) should connect to a Tx (-)
How do you call VHF radio?

What channel does marine VHF DSC operate on?
VHF channel 16
Background. VHF marine radios with digital selective calling (DSC) capability have a design function that enables automatic channel switching to VHF channel 16 when a DSC distress alert is received.
Does my VHF have DSC?
All new VHF radios are equipped with DSC capabilities. DSC radios have the ability to make ship to ship calls and access a distress channel. They transmit data digitally instead of using voice modulation, This allows DSC to have a far greater range than traditional VHF radio.
What is VHF DSC encoder?
Digital selective calling or DSC is a standard for transmitting pre-defined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS).
How do you wire a VHF?
Route the coaxial cable to the VHF radio’s back, attach the supplied connector to the cable, and plug it in. Any excess cable should be rolled in a coil of at least 8-inch diameter and stowed in an out-of-the-way place, away from other electrical cabling. You can shorten the cables, but no less than 3 feet in length.
What is an NMEA 0183 device?
NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined and is controlled by the National Marine Electronics Association (NMEA).
What VHF channel should I use for a radio check?
VHF Channel 09
Please use VHF Channel 09, which has been designated by the FCC as a boater’s calling channel.
