🔍 Key Concepts

• Digital Selective Calling (DSC) on VHF Channel 16 and its associated radiotelephone (voice) distress frequency • Relationship between Channel 16 DSC distress alerts and the follow-up J3E (single sideband) radiotelephony distress traffic • Differences between MHz vs kHz and typical maritime HF distress/urgency/safety working frequencies

💭 Think About

• First, recall what happens after a DSC distress alert is received on Channel 16: to which voice frequency is the radio usually switched for the actual distress traffic? • Look at the answer choices: which ones are realistic HF maritime distress/urgency/safety working frequencies that would be paired with a DSC alert on 16 MHz? • Check which choice has the correct order of magnitude and units (kHz vs MHz) for a standard maritime HF distress working channel.

✅ Before You Answer

• Verify the standard 16 MHz HF DSC distress frequency and its associated radiotelephony distress working frequency in the ITU/USCG tables (e.g., 16 MHz band). • Confirm which of the options is expressed in kHz, not MHz, and matches a known HF distress working channel rather than the DSC alert frequency itself. • Eliminate any option whose frequency band does not correspond to normal HF maritime distress/urgency/safety working channels.
