🔍 Key Concepts

• Digital Selective Calling (DSC) Distress procedure on VHF/MF/HF radios • The purpose of automatic repetition of an unacknowledged DSC distress alert • Recommended time delay before re-transmission in GMDSS procedures

💭 Think About

• Think about how quickly a distress alert should repeat if no coast station or ship acknowledges—should it be very short, moderate, or fairly long? • Consider that too-frequent repeats would cause congestion, but too-long delays could endanger lives: which time window best balances these? • Recall standard GMDSS training: what is the commonly taught automatic repeat interval range for DSC distress alerts?

✅ Before You Answer

• Verify the standard DSC distress repeat interval taught in GMDSS/ROC-GOC courses (usually given as a specific minute range). • Check that the chosen time is not so short that it would flood the channel with constant alerts. • Check that the chosen time is not so long that it would significantly delay further attempts to raise help in a real emergency.
