[Elecraft] (ot) noise reduction resources

[Kurt Pawlikowski]

Robert,

     Hum... About every 3 kc... Do they drift? I'd say that the 
"pull-the-plug" method of troubleshooting might yield interesting 
results. Maybe a washing machine or dryer or some other appliance. At 
least, that'd be my uneducated guess! Hope you find it!
