Q

What action should you take after sending a false or mistaken Distress alert on 12577.0 kHz?

🔍 Key Concepts

• False distress alert procedures in the GMDSS (Global Maritime Distress and Safety System) • Purpose of associated communications frequencies (voice vs. telex/data) • Who must be informed and reassured after a false distress alert

💭 Think About

• Think about what kind of transmission was made at 12577.0 kHz: is this primarily used for voice (J3E) or telex/data, and what is the matching way to cancel it? • Which single, immediate action would best alert all ships and coast stations on that band that the distress was false or made in error? • Ask yourself: which option addresses the mistake on the same service and band where it occurred, using a normal working/associated frequency?

✅ Before You Answer

• Identify whether 12577.0 kHz is linked to a specific 12 MHz voice (J3E) distress/traffic frequency or to HF telex only. • Check which option involves making an "ALL STATIONS" broadcast to ships and coast stations likely to have received the false alert. • Verify that the action directly cancels and explains the false distress (including time, ship name/call sign, and that there is no distress).
