This is really great stuff! I am monitoring 160m FT8 2 hours before
sunset so as to observe weak signals from Europe. RX setup is a K3 with
sub-receiver in diversity mode, a pair of 300m broadside co-phased
beverages (100m separation) to main RX and a BSEF 8-circle array to the
sub-receiver.
It is clear there is advantage to the spatial (stereo) diversity
component in this modified jt9 decoder. I am also monitoring the main
receiver audio with a vanilla WSJT-X / jt9 instance as well as with
JTDX. There are a small number of occasions when JTDX will pick up a
decode that is missed with any of the WSJT-X instances (both diversity
capable and not), but the diversity capable install clearly dominates.
I hope something like this may be considered for inclusion in the
mainline code.
Below is a small sample of the captures in a short observation window:

Hello friends!
Diversity patch for WSJTX 2.1.2 is ready for further testing.
On http://lea.hamradio.si/~s52d/ft8div
are three files:
zip file with sources, sample configuration files and description,
pdf file with 10 pages long patch description and
Windows 32 bit EXE file for WSJTX 2.1.2 with diversity patch included.
Changes compared to WSJTX 2.0.0 version are: FT4 works now, summing up
can be done faster on slower PCs,
description/guideline paper is almost usable.
Full RX diversity capabilities demand two coherent receivers like K3
or IC-7610,
but others might get it usable for frame level diversity or simple
time diversity.
Big thanks to WSJT developers team for releasing sources and making it
possible.
Best 73, mni DX
