I'm happy to report that I found the source of this terrible noise ! 


Although it was very random and only bothered me during parts of some contests 
I finally got tired of it and spent a week to find it.  Little mag loop antenna 
connected to K3 in my car.  Sniffed it out to two neighbors house.  


It was a Feit instant on LED light bulb screwed into an exterior garage door 
light fixture two doors down from me.  It only made noise when screwed into the 
left side garage light socket.  It was quite in the right side garage light 
socket.  It was a combination of bulb, socket and wiring.  It took about ten 
minutes for the bulb to start making noise. Neighbor has removed the offending 
bulb.  


Just to refresh your memory here is a recent video of this MONSTER.
