Dick, I experienced this same problem exactly on my SN 888, complete with intermittency of the symptom. After some consultation with Elecraft tech support, they sent me a KPAIO3 board -- the board that the KPA3 connects through and that contains the 12VDC sensor circuitry. Unfortunately, I haven't been able to get to installing it as yet. It's on the list for when I return from holiday vacation out of town. My bet is that this will cure the problem. I'll let the list (and Elecraft tech support) know when I swap it out and try it. Should be first week of January, possibly end of December.
