🔍 Key Concepts

• Emission designators structure: first symbol = type of modulation (e.g., F vs J), third symbol = type of information (e.g., B vs E) • Difference between telegraphy/data and telephony (voice) emissions • What type of modulation is used for MF-HF marine radiotelephone (SSB vs FM)

💭 Think About

• Which letter in the third position (B or E) corresponds to telephony (voice), and which to telegraphy/data? • For MF-HF long‑range marine radiotelephone, do we normally use FM or single‑sideband (SSB) modulation? Which first-letter code matches that modulation type? • Once you know it is voice telephony using SSB, which one of the options matches that emission combination?

✅ Before You Answer

• Identify which options end in E (telephony) versus B (telegraphy/data) • Recall that F is frequency modulation (FM) and J is single‑sideband suppressed‑carrier (SSB) • Eliminate any emission that is not both SSB and telephony (voice) before choosing from the remaining options
