Easy answer —
Your sample Lankford-Misek-Ratzlaff phaser
Does not have actual matched 50 ohm potentiometers in the “fine” controls —
They are “faked” 50’s using fixed resistors across the POT - which results in
squirrelly, unpredictable or unstable nulls.
All M-L-R PHASERS “sold” since that bet
Neil, I suspect that that was the case with my experiment. With the
shorter wire, and unamplified, no wonder the signal was too different in
strengths to get it to work properly. This will be a good spring/summer
experiment when I won't need to erect the N Beverage at all, freeing up
another ampl
I'd expect that to work. However, the issue is that you probably had
considerably more signal period on the amped BOG, so you need to attenuate
it to get a back null.
Ideally with these Phased BOG Systems you're looking to null back end QRM
while not reducing forward DX and hopefully the forward D
Bill the main amplified BoG was about 750’ long, while the parallel shorter
non-amplified BoG was about 600’ long with the feed about 50’ from the
primary, and the unterminated end about 100’ from the end of the primary
BoG. 73, Walt

Just noted 1380 Mexico at 0559:13z with the the Mexican National Anthem, on
November 13 in Newfoundland. No idea which station, but I'd say the Mexico
City station with the highest power is the likely culprit. This was on our
SouthWest wire, which I'm concluding is more west than south in effect.
Bill since aiming SW I'd suggest waiting for some AUish cx. 73 KAZ

Walt, approx, how long were your two wires? Here in IL a mini-PBS is giving

Bill, my phased array was similarly about 1.3 to 1, but more like about 5'
apart. Results were occasionally very interesting, but in the end, I
didn't use it very much (too much happening during TP openings). One down
side was that the shorter BoG was not amplified compared to the longer one,
so
