I too am about 1000 feet from one of the high tension lines...large 
metal towers. I've been here 27 years and never heard it. OTOH I've been 
off all except 75 and 40 for the past  couple of years.  I do still 
operate 144 and 440 FM but those are usually  not a problem.

My first real problem may have popped up since the big antennas came 
down for repair.  I mentioned it on another thread.  On 20 I hear a 
carrier every 60 KHz with sporadic digital modulation.  The higher 
bands, 15 in particular has the noise floor at S3 today.  It also shows 
up on 50.117 and 50. 148. It doesn't move the S-meter, but sure would 
play havoc with working Au signals down in the noise floor.  I killed 
the whole system, cable modem, router, and 8 port switch with 5 runs of 
CAT6, 3 of which are 130 feet long to the shop.  That made no difference.

I'm guessing it's a neighbor's router although it could be cable leakage 
as well.
