I can get within a 400'-500' circle, but can't see the source.  I can hear
it from 15 miles away, that's what got my attention, so it must be a fairly
large antenna at the source, I am guessing a 1/4 wave and most likely
mounted outside.  I am using a 24" whip and up to 131dB attenuation and can
get very close by spiraling in on the signal, but can only get so close,
within a few pieces of property and at times I can hear the signal on one
side of a street or only in front of one building, and cannot see any
antennas at any of the three sites.  I have talked to many people that own
property and buildings from where the signal appears to originate, without
luck.  I almost need some sort of sniffer, something small and hand-held
like a Geiger-counter, but that would also require being able to sniff
around the land and buildings, something I don't think people would go for.
