For meteor scatter on 6m and 2m, this version includes optimized timing for "pings," lowering the missed decode rate by approximately 15% compared to WSJT-X v2.2.

JTDX (Joint Transmission Decoder X) is a world-class fork of the popular WSJT-X software. While WSJT-X is the standard, JTDX is widely favored by the "DXing" community because it often decodes more stations in crowded or low-noise environments thanks to its optimized decoding algorithms.

JTDX is designed for amateur radio digital modes. Its primary goal is to improve the decoding of weak signals and provide a user-friendly interface for logging and station management. While it shares core decoding logic with WSJT-X, JTDX is often preferred by operators who want:

JTDX (Joint Terminal DX) is an community-driven fork of the original WSJT-X software developed by Joe Taylor (K1JT). Version 2.2.160 serves as a significant release candidate (RC) that introduces specialized decoding algorithms and user interface enhancements specifically tailored for crowded high-frequency (HF) bands. 2.
