Before diving into the update, a quick refresher: JTDX is a forked version of Joe Taylor’s WSJT-X, focused on providing even deeper decoding sensitivity and faster multi-stream processing. It supports the same core modes (FT8, FT4, JT65, JT9, MSK144), but uses different decoding heuristics. For many, JTDX is the go-to tool when signals are hovering at or below the noise floor.

: Version 2.2.160 builds often include updated Hamlib libraries (e.g., 4.5.x or newer), which improve rig control for modern transceivers like the FLEX-8000 series . jtdx 22160 updated
| Issue | Workaround | |-------|-------------| | Audio dropout after 1 hour | Increase USB buffer in Radio → Advanced → Audio buffer size = 512 | | No decode on 6m FT8 | Lower Rx depth to Normal (some rigs overload) | | CAT PTT stays on | Change PTT method to RTS on same COM port | | Logging to QRZ / HRD fails | Use ADIF export → manual import |
The latest updates in the 2.2.160 branch (builds rc9 and rc10) bring substantial refinements under the hood, specifically targeting decoders, hardware compatibility, and UI fixes. Before diving into the update, a quick refresher:
: Ensure your soundcard is set to 48 kHz sampling rate with 16-bit depth.

✅ Refined decoding sensitivity on weak signals. ✅ UI tweaks and stability improvements. ✅ Essential maintenance for the dedicated DX hunter.
The long-awaited JTDX v2.2.160 update has entered the hands of the community, bringing with it the essential tools required for the current era of digital DXing. By integrating the WSJT-X SuperFox decoder, the development team has ensured that JTDX remains a top-tier choice for operators chasing rare DXpeditions.
