What action should you take after sending a false or mistaken Distress alert on VHF?

🔍 Key Concepts

• VHF Channel 16 as the international distress, safety, and calling frequency • How to properly cancel a false distress alert under GMDSS procedures • Difference between DSC Channel 70 (digital selective calling) and voice channels

💭 Think About

• Ask yourself: On which channel did other stations likely hear or be alerted to your distress call, and how would you best reach all of them to cancel it? • Consider whether the initial alarm (DSC vs. voice MAYDAY) changes the requirement to make a voice cancellation message. • Think about which channel is continuously monitored by most vessels and coast stations for distress traffic.

✅ Before You Answer

• Verify which channel is designated internationally for voice distress and safety traffic. • Confirm whether standard procedures call for a spoken cancellation after a false alert, even if the alert was sent digitally. • Check that the chosen channel is one that all vessels are required to monitor for distress traffic, not just a working or bridge‑to‑bridge channel.
