We’ve recently begun experimenting with a WSJT-X derivative for FT8 and other JT Modes. Its called JTDX. The stated purpose of the JTDX software is (from the JTDX website):

JTDX supports JT9, JT65, T10 and FT8 © digital modes for HF amateur radio communication, focused on DXing and being shaped by the community of DXers.

The latest release candidate of of the JTDX software supports some interesting additional features beyond WSJT-X including:

• Additional FT8 and JT65 decoder options which can provide improved sensitivity
• Advanced automatic sequencing and QSO selection features
• Decoded messaging filtering features

We’ve been testing JTDX V2.0 release candidates here for about a month now. The feature additions definitely provide some useful enhancements. The software is derived from WSJT-X and we’ve been using it here for DX’ing and for weak signal FT8 work on 6 meters. It appears to have most of the features of the current version of WSJT-X with the notable exception of support for specific contest exchanges.

The JTDX software adds a number of FT8 decoding options that are useful on crowded bands and in situations when signals are very weak. These features can be selectively enabled to match band and signal conditions as well as the user’s available CPU horsepower. With all features enabled, JTDX seems to decode more signals on a crowded band than WSJT-X.
