Out of curiosity... with so many narrow-pattern receive antenna configs, how do
typical contest stations check different directions after a CQ? Frank, I still
want to come visit your station during a test and see how it all works.
Diversity and stereo headphones gets you to two different directions but I
wonder if there's some more powerful technique.
My station is much more modest, just a K9AY loop, and I rigged up a footswitch
system to let me scan different directions after CQ'ing in the contests. Still,
Bernie at J77A told me that I was ignoring him after my CQ's during the CQ 160
CW, and I'm guessing that's because I was mostly listening to the NE for Europe
and neglecting to scan the other directions.
Also, another one I suspect I may have missed by not rotating receive
religiously, was ZS6EZ, who I heard clear as day doing S&P with others.

In case anyone is interested in constructing a switchable 8-circle based on the
BSEF array, W9RE's PCB is laid out with provisions for Magic-Ts and step-up
auto-transformers where applicable, also the phase inverter. I finally got my
array up using Mike's board a week or so before ARRL160 and it does quite well
against the broadside beverage arrays, especially useful for diversity
