Q

Which channel is designated for GMDSS Digital Selective Calling?

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) purpose and how DSC fits into it • Difference between voice distress calling and digital selective calling (DSC) • Typical VHF channels used for distress, safety, and calling versus those used for signaling/DSC only

💭 Think About

• Which VHF channel is traditionally used for voice distress, safety, and calling, and is that the same as the DSC channel? • Is the DSC channel normally used for routine voice conversation, or is it reserved for signaling only between radios? • Among the options, which channel number do you most often see specifically linked to DSC alerts on modern GMDSS-capable VHF sets?

✅ Before You Answer

• Identify which option is commonly labeled on radios as "DSC" or associated with GMDSS functions. • Confirm which channel is not used for ordinary voice traffic but is reserved for digital signaling. • Make sure you distinguish between the traditional distress/calling voice channel and the dedicated DSC channel.
