Q

What VHF Channel is used for Digital Selective Calling and acknowledgement?

🔍 Key Concepts

• Digital Selective Calling (DSC) purpose and how it differs from voice calling • Standard VHF marine channel allocations (distress/safety vs. working vs. DSC-only) • Why one channel is reserved exclusively for DSC and not for voice

💭 Think About

• Which channel is traditionally used for distress, safety, and calling by voice, and is that the same as the one reserved for DSC data signals? • Among the options, which channel do you most often hear regular voice traffic on? Would that likely be dedicated to digital DSC? • Think about GMDSS (Global Maritime Distress and Safety System): which specific VHF channel number is associated with DSC distress alerts?

✅ Before You Answer

• Identify which option is the international distress, safety, and calling voice channel and separate that from DSC-only use • Recall which channel is designated as digital only (no voice) under GMDSS • Eliminate channels that are commonly used as working channels for routine port/ship traffic, since DSC is not done on those.
