Q

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

🔍 Key Concepts

• HF-DSC (High Frequency - Digital Selective Calling) distress procedures • Relationship between DSC distress frequencies and associated radiotelephony (voice) distress frequencies • ITU Radio Regulations table of HF maritime distress and safety frequencies

💭 Think About

• When a HF-DSC Distress alert is sent, what is supposed to happen immediately afterward in terms of voice communications? • How are DSC distress frequencies paired with specific SSB (single-sideband) radiotelephony frequencies for follow‑on traffic? • Look at which of the listed frequencies is designated internationally as an HF radiotelephony distress and safety frequency.

✅ Before You Answer

• Identify which option is an HF radiotelephony distress and safety frequency, not a DSC calling frequency. • Confirm that the chosen frequency is used specifically for distress, urgency, and safety traffic following an HF‑DSC alert. • Verify that the frequency you pick appears in the HF maritime distress and safety section of ITU or GMDSS reference tables, NOT in general working/traffic channels.
