Which type of voice mode is often used for long-distance (weak signal) contacts on the VHF and UHF bands?
- A.FM
- B.DRM
- C.SSB (correct answer)
- D.PM
WhySSB is the voice mode often used for long-distance, weak-signal contacts on the VHF and UHF bands. SSB concentrates all its power into a narrow bandwidth without a wasted carrier, giving it better range for a given power level than FM, which is why it's the preferred voice mode for weak-signal, long-distance VHF/UHF work, answer C. FM (A) trades range for its noise-quieting capture effect, DRM (B) is a digital broadcast standard rather than a common amateur voice mode, and PM (D) behaves essentially like FM for this purpose, not the mode actually favored for weak-signal contacts.
