Have a prob with a 3-way switch on a radio. Seems when I turn-it a produces
a awefull "sratchy" sound. Used a ton contact cleaner already.
When I touch it, seems to fade...grounding prob? Tried a wire to a gounding
point, still not all gone. Can this be fixed or new switch? dave

I really don't know what you are talking about when you say you have a
"3-way switch" on that radio. But regardless, it does sound like either
some kind of grounding issue, or possibly an antenna grounding issue. Sure
need more info on what you have there before making a better guess.
