[Elecraft] [K3] Keyer Pause

[Guy Olinger K2AV]

Gold gets goop from the air on it.  Very small particles of cooking grease
over a long period of time.  Soot from cigarette smoke.

Air is not pure just because you can see through it.  There is a small
charge on the contacts, and one side will attract particle out of the air.

This will coat gold the same way, if a lot slower, as stuff on my glasses
that needs to be washed off.

I've sometimes used a soft cloth saturated with alcohol-based eyeglass
cleaner to clean contacts.

73, Guy.
