I have some awful noise that is particularly high on 6 meters right now. It
shows up strongest in ssb modes rather than AM. The noise resembles 'wind'
or a 'rushing sound', as if listening to someone talking in a car with a
mobile radio and their window is down. The noise varies, has peaks and
valleys..what a pain in the but. Any ideas? - Mike

My first guess is that it is the clock in some sort of microprocessor.
If the humps drift, they're probably a switching power supply.
