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

[Juanma M. <jua...@gm...>]

Thanks Uwe.

This is decoding slightly more stations than JTDX Improved. First time that
WSJT-X outperforms JTDX.
Apparently completing decoding cycles faster than JTDX. So I will keep
using it for a few days. Looking good so far.
