Jerry,

These days, noise like that could come from any number of sources as lots of 
power supplies and micro-processor controled stuff generates RF noise.  I 
had a terrible noise sourse that wiped out the HF bands, especially 75 with 
a 30 DB noise.  after months of searching, I finally traced it to the power 
supply of my wife's computer.  She has a business building commercial web 
sites and her computer was always on.  I can't tell you why it never occured 
to me to check it sooner but when we shut it down the noise was gone.  Of 
course, she was delighted to have an excuse to replace her computer and that 
solved the problem.  I hope you find it soon.  You sure have my sympathies. 
Lou
