Section 5 - Sending and Receiving DSC Calls (US only)

5-1 What is DSC?

Digital Selective Calling (DSC) is a semi-automated method of establishing a radio call. It has been assigned by the International Maritime Organization (IMO) as an international standard for establishing VHF, MF and HF radio calls.

It had also been assigned as part of the Global Maritime Distress and Safety System (GMDSS). It is planned that DSC will eventually replace aural watches on distress frequencies and will be used to broadcast routine and urgent maritime safety information.

This new service will also allow mariners to initiate or receive distress, urgency, safety and routine calls to or from another vessel that is equipped with a DSC transceiver.

Calls can be categorized as distress, urgency, safety, or routine and DSC. It selects a working channel automatically.

Details of the 20 most recent incoming DSC calls are stored in your call log.

Details of the 10 most recent distress calls are stored in your distress log.

CAUTION

Due to EU regulations, DSC is not available in the LHR-80E (EU) model.

5-1-1 Maritime Mobile Service Identity

An MMSI is a nine-digit number used on Marine Transceiver capable of using Digital Selective Calling (DSC). This number is used like a telephone number to selectively call other vessels.
