JTDX 2.2.160, released in 2021, is a refined build of the JT65/JT9/FT8-compatible Windows client aimed at weak‑signal HF/700–50 MHz digital modes. Installation and setup are straightforward for users familiar with WSJT‑X-style software: the installer runs cleanly on modern Windows versions, and the UI keeps the classic waterfall, RX/TX panes, and logging fields in familiar positions.

This version introduced optimized algorithms to pull signals out of the noise floor, even when multiple signals overlapped.

Various "Release Candidate" builds (like rc3, rc7, rc8, and rc9) have been distributed, often within closed beta groups or via unofficial mirrors. Public Release Delay: Official public releases on platforms like SourceForge were reportedly postponed for an extended period. Unofficial Downloads:

Refined decoders for FT8 and FT4, and updated callsign databases (e.g., ALLCALL7.TXT ). Where to Download

Shared Hamlib libraries, allowing users to update libhamlib-4.dll independently to support newer radio hardware without reinstalling the entire JTDX suite.
