Larry,

I had a similar problem here last year. The culprit turned out to be an 
electronic "air purifier" aka ozone generator attached to the air handler on 
my neighbor's furnace/ac unit. S9 + 20 db QRM , broadbanded and drifint up 
and down the bands. Turned out that the unit, manufactured by RainSoft, was 
defective and they eventually replaced it. Have had no problems since.  The 
symptoms were that you could hear this crud on a portable receiver all 
around the block because it was being transmitted back out of their house 
over the power lines !!!!!!!!!

Drop me a note if you want more specific details.

Hope this helps.

73,
Dave, K2DP, St. Louis
