The legendary weak-signal communication software WSJT-X has reached version 3.0 Stable.

✅ Enhanced FT8 & FT4 decoding algorithms — pulls signals out of the noise floor like never before, achieving decodes at -24 dB SNR and beyond.

✅ Improved multi-decoder engine — simultaneously processes more signals in a crowded, noisy band, reducing missed QSOs.

✅ Better RFI rejection — smarter signal processing helps filter out man-made electrical noise and QRM from nearby stations.

✅ Optimized AP (A Priori) decoding — uses known callsign data to decode signals that would otherwise be lost in the noise.

✅ Refined frequency calibration — tighter frequency accuracy means cleaner decodes even when propagation is marginal.

✅ Low-power DXing made easier — work the world with just 5W even when the bands sound completely dead!

Whether you're dealing with urban QRM, solar flux challenges, or just a noisy shack, WSJT-X 3.0 gives you the edge to make those contacts happen! ????
