🔍 Key Concepts

• Digital Selective Calling (DSC) distress and safety calling frequencies • Difference between voice distress frequencies and DSC frequencies in MF/HF bands • Typical DSC pattern: certain kHz values repeat across MF/HF bands

💭 Think About

• First, which MF distress frequency around 2 MHz is used for DSC, and which similar one is for radiotelephone voice only? • Look at the 4/6/8/12/16 MHz options: do you recognize the standard DSC frequencies often listed together in GMDSS reference tables? • Check which choice keeps a consistent pattern of "DSC-only" frequencies across all bands, rather than mixing in common voice calling or working channels.

✅ Before You Answer

• Identify the correct MF DSC distress frequency near 2 MHz; eliminate any choice that uses the voice distress frequency instead. • For the HF bands (4, 6, 8, 12, 16 MHz), verify which exact kHz values you remember as DSC calling channels, not ordinary voice channels. • Make sure the set you choose matches an official GMDSS DSC frequency list (MF/HF DSC calling frequencies) rather than just looking "close" in value.
