سؤال 128

Which of these digital modes has the highest data throughput under clear communication conditions?

  1. MFSK16
  2. 170 Hz shift, 45 baud RTTY
  3. FT8
  4. PACTOR IVپاسخ درست

توضیح

PACTOR IV uses wide, high-order modulation across a full SSB channel with adaptive coding, so on a clean path it moves far more data per second than the others. FT8 is optimized for weak signals rather than throughput, MFSK16 and 45-baud RTTY are slow narrowband modes.
