I take it you are running two receivers? Seems to me a software solution is
possible.
Do we need to do any more than just average the two? In your example doesn't
look like time delays are needed for steering.

Having used diversity reception techniques as
far back as the 70s and knowing it was used in
the 40s to improve RTTY reception for mil comms,
that improvement is possible.
An early technique used 2 coherent R-390As and
dual fsk demod unit. The antennas were often
of different polarization
All good suggestions. Thank You.
Last night..
Double checked everything on the old dell i3 win10
and it started decoding just fine.
The thing is, that it is so slow, i loose track of what
i did and didn't do when i make changes.
And it takes forever to reboot.
I keep it around because it
Hi Ben,
You mentioned that you have two antennas. What kind antennas you have? Do they
have any radiation patterns different from each other? What’s distance between
the antennas?
In any case you can affect to the noise level by combining two antennas that
are at different locations. That beam

Also make sure that you are not in "Hound" mode with the "Rx All Freqs"
unchecked.

I have been messing around with WSPR decoding on 630m with a pair of
phase-locked receivers and two receive antennas.
I have put together some software to save two sets of coherent samples
for each 2-minute period, and then after the fact I can combine the
two sets of samples w/ a configurable
