I use De-Oxit. A drop between the contacts is allowed to sit there a few minutes, then the excess is removed by closing the contacts on a bit of paper. It solves the "dirty contact" problem for me. One treatment lasts many months.
My second favorite method is to gently close the contacts on a bit of paper and pull it out to "burnish" the contacts but, for me, that doesn't work nearly as well or last as long as the De-Oxit treatment. Ron AC7AC -----Original Message----- On the topic of keys, paddles, and bugs, I wonder if members of the list would tell me how they keep key contacts clean and reliable. Do you regularly burnish key contacts? Do you use a chemical cleaner (e.g. de-oxit)? Do you maintain a minimum keying current? Or do you simply never have a problem? Please share your wisdom and experience. 73, John, no8v _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
