Question 1 of 27070

Q

Which emission mode occupies the most bandwidth?

🔍 Key Concepts

• Emission designators and what each character means (e.g., J3E, F3E) • Typical bandwidths for FM voice vs single sideband (SSB) vs FSK/teletype emissions • How angle modulation (FM) compares in bandwidth usage to amplitude-based modes

💭 Think About

• Look up or recall what each mode (J2B, F3E, J3E, F1B) represents in plain language, then compare their usual occupied bandwidths. • Ask yourself which of these modes is commonly used for wideband voice communications and which are used for more narrow data/teletype signals. • Think about how single sideband with suppressed carrier compares in bandwidth to full‑carrier FM voice on the same band.

✅ Before You Answer

• Identify which options are voice emissions and which are data/telegraphy. • Confirm which of the listed modes is frequency modulation (FM) and which are single sideband (SSB) or keyed/FSK modes. • Verify from a radio reference which emission type is normally assigned the largest kHz bandwidth in marine/HF/VHF practice.
