Your ship received a Distress relay from a coast station on DSC VHF channel 70. What action should the watch officer take?

🔍 Key Concepts

• DSC (Digital Selective Calling) distress relay procedures on VHF • Which VHF channel is used for distress, safety, and calling voice traffic after a DSC alert • The difference between DSC alerts on Ch-70 and follow-up voice traffic

💭 Think About

• After a coast station sends a DSC distress relay on Ch-70, what is the standard follow‑up step for ships that receive it? • Which channel is internationally designated for voice MAYDAY traffic and distress communication monitoring? • Is it normally correct for an individual ship to immediately rebroadcast a DSC distress alert received from a coast station?

✅ Before You Answer

• Identify which channel (by number) is reserved only for DSC and not for routine voice traffic • Verify which channel is the international distress, safety, and calling channel for voice on VHF • Consider whether a ship should originate a Mayday Relay call by voice when a coast station has already issued a DSC distress relay
