Not so much one cavity more than the other... but on the TX side more than the other.

You're almost at the problem. No garbage with tapping, beating and banging is a good sign. One might guess you have some type of micro pitting and at least one hard point pitted contact on one of the mating surfaces. One or more of the metal plunger contact surfaces has a not easily viewed problem. Just cleaning might not cure it.... sometimes you need to replace finger stock and or have at the surfaces with the proper cleaning brush/function. You didn't say how you'd cleaned the surface in the past. I would only use a Brass or hard Stainless Steel brush to avoid embedding non same metals into the plunger or contact surface. Using a common steel wire brush is not a good idea. s. > "Mike Besemer \(WM4B\)" <[EMAIL PROTECTED]> wrote: > Skipp, > > Doing that produces some interesting noises in the receiver. > It will go from full-quieting to complete garbage without > much movement.
