Dont rule out a new mattress pad heater power supply.  I had a neighbor who 
got one, it was really nasty...had to go to the manufactuer and get new 
power supplys for it...then it was fine, took a long time however.  It had a 
tick up and down all the HF bands and up to 2M +.  I DFed it there and asked 
if they had added anything...nothing but a mattress warming pad.  I asked 
here to turn it off and bam it was gone.  Hope your neighbor is as nice as 

The mattress pad was from "Perfect Fit" Industries.
