[Elecraft] [KPA500] that's what I was running, definitely causes the problem

Steve,

Some are having the problem it seems, I did and somehow I fiddled long
enough it got tired of playing with me, or maybe it took pity on an old man
and quit...:-)

FW sure is a 'Black Art' at times, or so it seems.

For now, mine is behaving, I know not why, but it's playing in the sand box
nicely and that is a good thing.
