DSC on VHF is used for what purpose?

• A. Routine Calls
• B. Distress Calls
• C. Position Reporting
• D. Weather Updates

Answer: (B)

Digital Selective Calling on VHF is built to get help fast when things go wrong. It sends a digital distress alert that automatically notifies rescue authorities and other DSC-equipped stations, usually including your identification and your location if a GPS is linked. This makes it the quickest and most reliable way to summon emergency assistance when you can’t or don’t want to speak. While DSC can also be used to call specific vessels or groups, the primary purpose in an emergency is to initiate distress signaling. Routine voice calls and weather updates aren’t the目的 of DSC; those tasks use voice channels or other sources of information.
