Some hams prefer WSJT-X for its simplicity. But JTDX v2.2.160 retains its faster waterfall refresh rate and multi-decoding passes—critical when a brief 160m opening appears and disappears in minutes. FT4 is fine for contests, but for weak-signal DX on 160m, JTDX’s deeper sensitivity wins.
Early testing shows that the new AP (a-posteriori probability) decoder is more aggressive yet accurate on marginal signals. If you’ve watched a weak 160m station flash in the waterfall but never decode—this update might finally pull their call out of the muck. jtdx 2.2 160
[JTDX official site link] 73 & good decodes! Some hams prefer WSJT-X for its simplicity
A few users report that v2.2.160 sometimes double-decode the same transmission on 160m when using very long (30s) Rx periods. A simple fix is lowering the “Decode after” time to 0.5s. Expect a patch soon—but it’s not a showstopper. Early testing shows that the new AP (a-posteriori
If you’ve been frustrated by 160m’s “wall of noise,” give this new JTDX a spin. You might finally log that KH6 or ZL on Top Band.
The release notes mention “improved sync stability for very low SNR.” In plain English: the software now handles the long, deep fades typical of 160m NVIS and gray-line propagation. You’ll notice fewer partial decodes and more clean callouts, even when the band sounds dead to your ears.
