So, as Lyle (KK7P) and Brian (K3KO) are saying, this is due to (1) having the KPA500 set to K3 (I do), and after the amp sits and capacitors discharge, there is no voltage coming through the acc connector and the amp goes to 60 meters. Well, if that's the case then I guess there isn't much that can be done about it. Sighhhhh....... Tnx, Jim
