[RFI] [Fwd: Noise Follow up]

If it's *exactly* like noise source # 3, then it is not coming from someones
house.  Don't be mislead.  That is classic 100% loose hardware type noise.
I bet it goes away with wet weather, too.  It is easy to pinpoint with an
all band receiver (AM or SSB at least, I use the ICOM R-10)  and a yagi.
Just go up in frequency as you get closer.  RFI at 144 mhz can travel quite
a distance, so 440 mhz yagi will narrow it down to a specific pole 99% of
the time.  ON rare occasions I have had to use a 900 mhz yagi to pin it

Good luck
