Question 474What is the bandwidth of an FT8 signal?10 Hz50 Hz✓Bonne réponse600 Hz2.4 kHzExplicationFT8 uses eight-tone FSK at a symbol rate of 6.25 baud and 6.25 Hz between adjacent tones. Eight tones spaced that way occupy about 8 × 6.25 = 50 Hz, which is why many FT8 signals fit side by side inside a single SSB passband.
