🔍 Key Concepts

• Digital Selective Calling (DSC) distress watch frequencies in the MF/HF bands per GMDSS requirements • Difference between radiotelephone distress frequencies and DSC distress alert frequencies • Typical MF DSC distress frequency near 2 MHz and how HF DSC channels are spaced in ITU tables

💭 Think About

• Look carefully at which option lists frequencies specifically designated for DSC distress watch, not for voice distress traffic • Compare the 2 MHz band frequencies in each choice to the known MF DSC frequency and eliminate options that clearly show voice distress instead of DSC • Notice the pattern and spacing of the HF frequencies in each list; which set matches the standardized DSC HF channels used in GMDSS?

✅ Before You Answer

• Identify which 2 MHz frequency in the options is the MF DSC distress frequency (not 2182 kHz) • Check if each HF frequency in the chosen option corresponds to a recognized DSC distress/urgency/safety channel used for automatic watchkeeping • Verify that the correct set contains only DSC channels, with no mixed-in radiotelephone (voice) distress frequencies
