What are the assigned frequencies for VOICE and SITOR (NBDP) follow on communications?

🔍 Key Concepts

• Distress vs. follow-on working frequencies in the MF/HF bands • Typical MF voice follow-on channels near 4 MHz and HF voice follow-on channels near 8 MHz and 16 MHz • Standard NBDP (SITOR) follow-on working frequencies that pair with those voice channels

💭 Think About

• Identify which listed VOICE frequencies are commonly used after an initial distress call, not the distress calling frequencies themselves • Look for SITOR (NBDP) frequencies that are recognized MF/HF digital selective working channels that logically pair with follow-on voice bands • Ask yourself: which option keeps distress calling frequencies (like 2182 kHz) separate from the working/follow-on frequencies?

✅ Before You Answer

• Make sure MF distress frequency 2182 kHz is not being used as a follow-on working voice frequency in your choice • Confirm that the NBDP (SITOR) frequencies are in the correct digital working channels (e.g., 2174.5 kHz is digital, not voice) • Verify that the VOICE set you choose includes standard follow-on channels around 4 MHz, 8 MHz, and 16 MHz for MF/HF radiotelephony
