Little used in Australian waters.
Digital Selective Calling is a standard developed to send pre-defined digital distress messages via medium frequency (MF), high frequency (HF) and very high frequency (VHF) maritime radio bands. Tas Maritime does not monitor DSC.
DSC is primarily a system for alerting other stations when there is no one listening on a voice calling frequency (such as channel 16). As TMR has a 24/7 listening watch on channel 16 - and on HF calling frequencies (day only on HF), we do not anticipate the need for DSC in the Tasmanian region.
