The two pins in KX3 that mate with KXPD3 were recessed a few mm. After pulling back, the key works fine. I must have inserted KXPD3 too hard, and the pins gave out. I wonder how to secure the pins from recessing. Crazy glue, epoxy, or something else. Ignacy, NO9E -- Sent from: http://elecraft.365791.n2.nabble.com/
