Thanks! I just threw one of these together and it works! I can hear
the noise in question re-radiating from my 160 vertical while
standing 7 or 8 feet away. That's not far, but considering this is
re-radiation from a source at least 700 feet away (probably more)
I'm hoping it will be sensitive enough to hear the source when I get
close enough to it. I have no idea what it is I'm chasing. The loop
has a nice figure 8 pattern "as advertised".
After a quick lunch I am headed off to see if I have any luck
finding this noise...

I use a simple loop. A half dozen turns of leftover insulated copperweld
about 18" in diameter taped to a fiberglass electric fence rod. Directly
attach rg-58 or 8x coax and wind as many turns as possible through a big
ferrite to make a choke for the feedline. Gives a nice figure 8 pattern but
pretty low sensitivity. maybe add a preamp for weaker signals? maybe more
turns would be more efficient?
