When I got back on topband in 2002 I discovered the band had been 
invaded by what might best be described as unstable growls, each 
about 3 kHz wide, between 1810 and 1820. There used to be several, 
then last year there was just one. This season there is just one, 
but it seems consistently higher in frequency than the one I had 
last year. These things drift around a bit. There is very little 
change in strength when I switch receiving directions. The noise 
seems to come from everywhere, perhaps radiating from many points. I 
discovered I can also hear them at the club station, 2 miles away.

A few years ago I suddenly had a much stronger one show up. It 
turned out to be a bad computer power supply in my own home. That 
one did vary in strength as I switched antennas, strongest when on 
the Beverage pointed toward my house.
