[RFI] Powerline noise question

[Richard Karlquist]

I have a powerline noise coming from about 2 miles away, which is
nevertheless quite strong at my QTH. 

Here are the symptoms: 

1.  A 120 Hz noise burst at regular intervals, about 0.9 seconds apart. 

2.  The noise goes away after a rain; then comes back after things dry
out. 

3.  Can be heard from 500 kHz up to a few MHz. 

4.  The noise is very strong along a road for a few miles.  There is a 

power line that follows the road.  I haven't been able to localize it
better than 

that so far.  From my QTH, though, it is definitely coming in at a
specific azimuth 

which is consistent with the noisy road a few miles away.  (Using a loop
antenna 

for DF'ing). 

Any help appreciated.
