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):
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.
JTDX Main Window and Waterfall
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.

We held our latest Technician License Class the weekend of February 23rd and 24th, 2019 at Dartmouth-Hitchcock Nashua. It was a big success! We had a great set of students who were well prepared for the class. All 13 students in the class passed the Technician Exam and 11 of those students became new members of the Nashua Area Radio Society! They are now anxiously awaiting their callsigns.
