1.DSC SYSTEM OVERVIEW

1.1What is DSC?

DSC is an acronym meaning Digital Selective Calling. It is a digital distress and general calling system in the MF, HF and VHF bands used by ships for transmitting distress alerts and general calls and by coast stations for transmitting the associated acknowledgements.

For DSC distress and safety calling in the MF and HF bands the frequencies are (kHz) 2187.5, 4207.5, 6312.0, 8414.5, 12577.0, and 16804.5.

The DSC-60 is a combination MF/HF DSC Terminal and Watch Receiver. Connected to an SSB radiotelephone, the DSC-60 sends and receives calls via the SSB radiotelephone. The built-in remote control permits control of a FURUNO radiotelephone from the DSC-60.
