The problem with KX3 in TX when KXPD3 is fully inserted started just 2 weeks ago. Perhaps one air travel with rough treatment too many. Before everything was fine. If I put a blade of a small pocket knife between KX3 and KXPD3, the key works OK. Ignacy, NO9E -- Sent from: http://elecraft.365791.n2.nabble.com/
