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. Systems with receive latency greater than 0.2 s will see smaller improvements, but will still see many decodes earlier than before. Overall decoding yield on crowded bands is improved by 10% or more. ![]() A second processing step starts at 13.5 s, and the final one at 14.7 s. 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. Improved and extended the algorithm for AP decoding.įT8: Decoding is now spread over three intervals. WSJT-X 2.2.0 Download new version WSJT-X: New in Version 2.2.0 Improvements to decodersįT4: Corrected bugs that prevented AP ( a priori) decoding and/or multi-pass decoding in some circumstances.
