| FT8 mode od K1JT |
| Trwają prace nad nad nową wersją WSJT-X 2.2.0 https://physics.princeton.edu/pulsar/K1JT/wsjtx.html Powstała wersja rc1 którą można już testować. Dekoduje w trzech przebiegach, moim zdaniem dekoduje jeszcze więcej stacji. New in Version 2.2.0-rc1 Improvements to decoders FT4: Corrected bugs that prevented AP (a priori) decoding and/or multi-pass decoding in some circumstances. Improved and extended the algorithm for AP decoding. FT8: Decoding is now spread over three intervals. The first starts 11.8 s into an Rx sequence and typically yields around 85% of the possible decodes, so you see most decodes much earlier than before. A second processing step starts at 13.5 s, and the final one at 14.7 s. Overall decoding yield on crowded bands is improved by 10% or more. Systems with receive latency greater than 0.2 s will see smaller improvements, but will still see many decodes earlier than before. SNR estimates no longer saturate at +20 dB, and large signals in the passband no longer cause the SNR of weaker signals to be biased low. Times written to cumulative journal file ALL.TXT are now correct even when the decode occurs after the T/R sequence boundary. In FT8 DXpedition Mode, AP decoding is now implemented for Hounds when the Fox has a compound callsign.
