Q

If a VHF-DSC Distress alert is transmitted what channel is used for follow-on voice transmission?

🔍 Key Concepts

• VHF-DSC (Digital Selective Calling) uses one channel for digital alerts and a different channel for voice communication • The international calling and distress voice channel for GMDSS sea areas is standard worldwide • Know the difference between the digital distress alert channel and the follow-up voice distress traffic channel

💭 Think About

• Which channel is reserved only for DSC digital signaling and not for normal voice traffic? • After the DSC alarm goes off, on what channel do you actually talk to handle the distress? • Among the options, which channel is internationally recognized as the voice distress, safety, and calling channel?

✅ Before You Answer

• Identify which option is the DSC-only digital channel and eliminate it • Confirm which channel is used worldwide for distress, safety, and calling by voice • Make sure the channel you choose is permitted for voice traffic, not reserved exclusively for DSC signaling
