: Topband: Polarization on 160m
Speaking of "two ears"
Going back to using two Drake R4B receivers, two antennas, one on each
ear, there would be times when "two ears" heard the signal, while
switching to each other there would be nil. I think that was some DSP
going on in the

BTW Drake R4B is still one of the best
WIll add my two cents to this discussion.
One thing I have experience with is diversity reception both on 160 and 80
meters. Often - I would be using my TX antenna in one ear and a beverage
in another. On 80 meters, the TX antenna was a 4 square. On 160, either a
vertical or two element phased
Not knowing about "gyros", but when operating and having vertical and
horizontal antennas available, I remember times when QSB was happening
on one antenna, switching to the "other" polarization antenna would
bring the signals up.
My conclusion was that at the times the signal's polarization
Polarization on 160m
Interesting discussion and one I suspect we wish could fully comprehend !
When the wave front meets the ionosphere and the wave splits the
critical frequency is different for the two waves, commonly known as foc and
fxc.
This difference (from memory) is half the
Thanks to everyone for your comments on polarization. I certainly agree
with Tom W8JI in that this discussion is a brain exercise (he also said
enjoyable). It forces me to delve deeper to asses whether I have a
screwed-up understanding of all of this. And he has a good point in that
this is a
