What type of modulation is commonly used for VHF packet radio transmissions?
- A.FM or PM (correct answer)
- B.SSB
- C.AM
- D.PSK
WhyFM or PM is the type of modulation commonly used for VHF packet radio transmissions. VHF packet radio transmissions are typically carried on an FM or PM voice channel, with the digital data modulating an audio subcarrier the same way a voice signal would, answer A. SSB (B) and AM (C) aren't the usual choice for VHF packet, and PSK (D) describes a different, HF-oriented digital modulation scheme, not the FM-based packet common on VHF.
