Steve, have you looked at the ARRL "Sounds of RFI" page to see if you can find a match?

On 40M I heard a lot of noise, most likely QRM, .. shut my overhead dimmer to the shack (no help). It was a tick-tick-tick and about 100+hz. Very annoying. Not on other bands. Pressed the NB button and all went away. I'm new to this and thought that would be more for vehicle type noise (alternator/vehicle computer/etc.) but it worked for me. To the seasoned folks you probably already knew this, but I'm a "youngster" at this.
