I agree that Ed misused the term "polarity" at the end of his post, but
I'm pretty sure it was a slip of the pen (keyboard) because he has been
doing this stuff for a long time. I'm pretty certain he meant
"polarization". I know he has done some work (and written about it)
using cross
Some words are being misunderstood and mis-used.
Polarization describes the geometric orientation of the antenna and the
resulting EM field. Polarity is the positive or negative going sense of
voltage or current in a circuit (what for decades we mistakenly called
"in phase/out of phase).
Dave AB7E,
I have been doing something similar with my K3 with subRx:
I feed signals from two antenna that are orthogonally polarized (one
is horz and other is Vert polarity, both pointed in the same
direction and essentially in-phase).
I use the eme sw MAP-65 to process the output of both Rx

Not sure what you are describing. If you mean two antennas feeding two
receivers at RF for diversity reception, yes ... that works well but is not
the same thing at all. Your brain is doing

Over the past few years I have twice requested Elecraft include
something like that as a software modification, but nobody (either at
Elecraft or here on the list) seems interested in the least. Since phase
is preserved during down conversion in a superhet circuit the software

A late model SDR Receiver (only) is said to have a soon to be released
software update. I've seen a demonstration whereby using 2 antennas and a
computer device, the unit will be able (to some degree?) determine signal
direction.
Does Elecraft have plans to develop K4D software with such
