🔍 Key Concepts

• Digital Selective Calling (DSC) purpose and which VHF channel is reserved for it • Difference between DSC distress alerting and voice (radiotelephony) distress calls • Which VHF channels are internationally designated for distress, safety, and calling

💭 Think About

• First, recall which single VHF channel is internationally designated ONLY for DSC distress, safety, and calling – not for voice traffic. • Think about the standard sequence: What do you send first in an emergency – the DSC alert or the MAYDAY voice call – and on what channel is that initial alert sent? • Look at each option and ask: Is this channel actually used for routine bridge‑to‑bridge or intership communications, or is it reserved for distress alerting?

✅ Before You Answer

• Verify which channel number is specifically reserved for VHF DSC distress, safety, and calling under GMDSS. • Confirm whether Channel 6 is used for distress alerting or mainly for intership safety communications by voice. • Check that the mode in your choice matches the intended use: DSC for digital alerts vs radiotelephony for MAYDAY voice calls.
