Expand description

One successfully decoded FT8 message.

Fields§

§message77: [u8; 77]

Decoded message: 77 bits packed as bytes (LSB first within each byte).

§freq_hz: f32

Carrier frequency (Hz)

§dt_sec: f32

Time offset from the nominal 0.5 s start (seconds)

§hard_errors: u32

Number of hard-decision errors in the final codeword

§sync_score: f32

Sync quality score from fine sync

§pass: u8

Which LLR variant decoded successfully (0=llra, 1=llrb, 2=llrc, 3=llrd)

§sync_cv: f32

Coefficient of variation of the three Costas-array powers (score_a/b/c).

Near zero for a stable channel; elevated (> 0.3) when QSB or strong time-varying fading is present. Used by decode_frame_subtract to apply partial subtraction gain when the amplitude estimate is unreliable.

§snr_db: f32

WSJT-X compatible SNR estimate (dB).

Computed from decoded tone power vs. opposite-tone noise power: 10 log10(xsig/xnoi − 1) − 27 dB. Floor is −24 dB (same as WSJT-X).
