- B) FT8, FT4, and FST4
- C) Winlink, PACTOR II, and PACTOR III
- D) DMR, D-STAR, and SystemFusion
Correct Answer: D
Explanation
Digital Voice (DV) modes use a digital vocoder to compress and digitize the operator’s voice before transmission. These modes are typically used on VHF and UHF amateur bands, often via repeaters.
The primary, widely used digital voice systems in amateur radio are DMR (Digital Mobile Radio), D-STAR (Digital Smart Technology for Amateur Radio), and SystemFusion (Yaesu’s digital mode). The other options are data transmission modes (WSPR, Winlink, PACTOR) or weak-signal modes (FT8/FT4) which are not designed for real-time voice communication.
