What is the calling and distress frequency on a single side band (SSB) marine radiotelephone?

🔍 Key Concepts

• SSB MF distress and calling frequency used internationally before GMDSS VHF Ch 16 took primary role • Difference between MF (kHz) and HF (MHz) marine bands • Common traditional voice distress signals: "Mayday" on VHF Ch 16 (156.8 MHz) vs. MF SSB frequency in kHz

💭 Think About

• Think about which of these numbers looks like a well‑known, internationally recognized distress frequency for voice on MF SSB, similar in status to VHF Channel 16 • Compare the options: which one have you most often seen paired in books, tables, or posters with VHF Channel 16 as the older standard radiotelephone distress frequency? • Recall that international calling and distress frequencies were designed to be easy to remember; which of these kHz figures looks most familiar from standard exam study materials?

✅ Before You Answer

• Verify which specific MF SSB radiotelephone frequency is designated for calling and distress in standard marine radio tables (not CW/Morse or DSC) • Confirm that the frequency you choose is in kilohertz (kHz) and is historically associated with voice distress (radiotelephone), not digital selective calling (DSC) • Cross‑check that the frequency you select is recognized in ITU/USCG radio exam references as the primary MF SSB calling and distress frequency for voice traffic
