I had this problem with #23, when I initially powered it on you couldn't power it off with the power switch. The cause turned\out to be that I had turned the sub receiver AF and RF gain controls full clockwise and through some quirk in the firmware, since there was no SUB receiver, the power off function was inhibited. The solution was to turn those controls full CCW. Wayne was the one who spent a lot of time with me solving the problem.
So you might want to check that, I haven't tested to see if the problem recurs in mine if I move the controls off CCW. Ah, brings me back to my software/firmware development days. There are NO bugs, only "features" Doug W6JD -------------- Original message -------------- From: "David Yarnes" <[EMAIL PROTECTED]> > Hi All, > > There are at least two of us here in Tucson with K3's.
