[RFI] Line noise KUB Knoxville

All:

Just starting in the past few days I've got an S9 plus 20db buzz that is 
easily heard on a AM car radio over a half mile or more that 
unfortunately peaks near my home.  It completely wiped out a local 
station on 670kHz as I returned home yesterday.

The local lines and poles were replaced just a few months ago by Pike 
because of the age of the poles and frequent power outages. Not because 
of any complaint from me.  I did think I'd be relatively free of noise 
for a while, so go figure.

I've pulled the main feed to the house and heard no change.

I can do a pretty decent job of nulling the noise with an MFJ-1026 and 
my opinion is that I'm hearing a single source.

I intend to wait until we get some rain to see what may happen. It's 
dusty dry here at present. One more clue.

I used to know some of the radio guys at KUB but they have all retired 
and I dread making the call to them. I expect to be sent to the 
department dealing with wireless meter complaints and other cranks.

Do any of you have any contacts at KUB or perhaps know what the name 
might be of the internal department that handles RFI trouble?
