Digital Selective Calling

GMDSS-SRC-M1 · Radio fundamentals · GMDSS-SRC-M1-A How VHF works, what each channel is for, DSC and the identities behind it.

DSC turns a VHF set into a **digital alerting system**. One button sends your identity, position and the nature of distress to every station in range. Used properly it saves lives; used carelessly it sends lifeboats to a yacht whose guest pressed the red button.
