JTDX means "JT modes for DXing", it is being developed with main focus on the sensitivity and decoding efficiency, both, in overcrowded and half empty HF band conditions.
It is open source software distributed under the GPL v3 license, and is based on the WSJT-X r6462 source code.
Optimal candidate selection logic, four/five pass decoding and decoders based on the matched filters making JTDX performance quite different from WSJT-X software for operation on the HF bands.
Almost all work goes around JT65 mode, decoding efficienсy of JT9 mode is the same as in WSJT-X and might be addressed in the future JTDX versions.
Initially based on the enthusiasm, now in average it taking close to 12 hours of daily work and your donations would be the only way to let me proceed with the further JTDX software development.
Many thanks for your support,
73, Igor UA3DJY
