4-1 What is DSC?
DSC (Digital Selective Calling) is a semi-automated method of establishing VHF, MF, and HF radio calls. It has
been designated as an international standard by the IMO (International Maritime Organization) and is part
of the GMDSS (Global Maritime Distress and Safety System).
Currently, you are required to monitor Distress Channel 16, but DSC will eventually replace listening watches
on distress frequencies and will be used to broadcast routine and urgent maritime safety information.
DSC enables you to send and receive calls from any vessel or coast station that is equipped with DSC func-
tionality, and within geographic range. Calls can be categorised as distress, urgency, safety, or routine, and
DSC selects a working channel automatically.
