[RFI] What's the QRM on 7.260MHZ?

[Paul K.]

I have been hearing a "frying" sounding interference around 7.260 MHz+/- 
every day in the morning about 1500UTC.  I can see it on the 
panadapter.  The signal is about 25KHz wide, and is being heard by a 
fellow ham 5 miles away.  I'm convinced I'm not listening to the local 
power company noisy poles.

Is any one else hearing this?  I'm west of Knoxville, TN
Any ideas about the source?
