12.9 VHF DIGITAL SELECTIVE CALLING
Digital Selective Calling is a semi-automated method of establishing a VHF radio call. DSC
had also been designated as part of the Global Maritime Distress and Safety System
(GMDSS).
This new system allow mariners to instantly send a distress call with GPS position (when
connected to the transceiver) to the US Coast Guard and other vessels within range of the
transmission. DSC will also allow mariners to initiate POSITION Request, POSITION
Report calls to or from another vessel equipped with a DSC transceiver.
Compatible VHF Marine Radios with Digital Selective Calling are able to be interfaced with
the GPS Chart Plotter which feeds GPS data to the VHF and listens for DSC calls from the
VHF. By connecting a few wires between the compatible DSC VHF radios and the GPS
Chart Plotter it will receive:
1. a vessel that has transmitted a DSC Distress call
2. a vessel that has transmitted a DSC Position Send Call
3. The position of a vessel that transmitted a DSC Position Request Call
12.9.0 Interfacing
To take advantage of these functions the GPS chart plotter must be interfaced (wired) to
a STANDARD HORIZON or compatible DSC VHF.
For additional information refer to Par. 2.4 Connections.
12.9.1 Distress Call
STANDARD HORIZON GPS chart plotters are able to display the location of a vessel in
distress when interfaced to a compatible DSC VHF with NMEA 0183 output and the radio
