The proper sequence of emissions corresponding to the sequence SSB-Voice without carrier, USB-Voice with carrier, FM-Voice and SITOR (NBDP) TELEX is:

🔍 Key Concepts

• Radio emission designators structure (first symbol = type of modulation of main carrier, second = nature of signal modulating carrier, third = type of information) • Difference between J3E vs H3E (single sideband suppressed carrier vs single sideband with reduced/inserted carrier) • Which emission designator is used for FM voice and which for NBDP/SITOR telex

💭 Think About

• Match each part of the sequence (SSB with/without carrier, FM voice, SITOR telex) to the correct emission designator letters, then line them up with the answer choices • Ask yourself: which of J3E or H3E corresponds to SSB "without carrier" and which to SSB "with carrier"? • Identify which designator ends with "3E" (voice/telephony) and which ends with "1B" (data/telex) and align them with FM voice vs SITOR telex

✅ Before You Answer

• Confirm that all voice emissions in your chosen option end with "3E" and the telex/data emission ends with "1B" • Verify that the first two positions in your chosen sequence reflect SSB without carrier first, then SSB with carrier, not the other way around • Double‑check that FM is always represented by a designator starting with "F" in the options you are comparing
