Which channel is used for survival craft portable VHF radiotelephone equipment?

• A. Channel 70
• B. Channel 13
• C. Channel 16
• D. Channel 9

Answer: (A)

Channel 70 is used for DSC on VHF maritime radios, and survival craft portable VHF equipment relies on this dedicated digital calling channel to send distress and safety alerts. Keeping DSC on Channel 70 prevents DSC signals from clashing with voice traffic on the voice channels, ensuring rescue coordination receives the alert reliably. After a DSC distress is sent on Channel 70, you can establish voice communication on the appropriate channel (often Channel 16) if needed. Other channels serve voice hailing or bridge-to-bridge functions, but the survival craft device uses Channel 70 for its distress/safety signaling.
