While WSJT-X typically decodes down to -24 dB SNR, JTDX 2.2.160 reliably decodes as low as (and sometimes -33 dB) in real-world conditions. This is achieved through improved soft-decision FEC processing and a custom iterative decoder.
Not officially, but you can copy the installed folder to a USB drive and run it with --config portable flag.
Conclusion JTdx 2.2.160 exemplifies how a mature, specialist amateur-radio client evolves: through incremental stability, usability, and decoding refinements that matter most to active weak-signal operators. Upgrading is usually worthwhile for stability and small sensitivity gains, but operators who depend on rock-solid behavior for contests or DXpeditions should validate the new build in test conditions and ensure surrounding systems (clock sync, audio routing, and rig control) remain correctly configured.
