Re: [Jtdx-improved-community] v3.0.0 of WSJT-X Improved brings a new multithreaded FT8 decoder

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi,
Well done Uwe 👏

Did some short test and compared latest JTDX 2.2.160 rc9 beta version
available only for a small group of testers with Wsjt-x 3.0 and I can say
that now Wsjt-x can decode much better on a crowded frequencies.
The wsjt-x decoder is a bit slower but it is good enough or equal to latest
JTDX.
Did use normal settings in JTDX,  with all settings set to high I would see
few more decodes probably in JTDX. Still using an old I5 but is good enough
for such tests.

Will try to find somewhere 100+ stations wave file and make new tests.
Another thing would be compare decoding FT8 Wide eTEP flutter signals on 6m
band.

73, Patrik 9A5CW
