[Kenwood] Relays in Rigs

Wed Jan 28 17:14:56 EST 2015

I would make the cleaning jig shown in ASB-0902. When I got tired of using
it every year or so I would do the mod shown in the same service bulletin
to continuously apply a wetting current and get rid of the problem. I would
not even attempt to manually clean 14 relays which wouldn't last as long
as the electrical cleaning.
Just as a note the relays are 3/8"x5/8" in size and the later 430's used
sealed relays. The contacts are the size of a pin head. Have fun cleaning.
