I've noticed a similar inconvenience. The problem for me is that Tune will not activate if PTT is asserted at the rear panel. In my station I don't have the amp hooked up to the Key Out of the radio. I have a foot switch that asserts PTT to the K3, puts the amp in transmit, and switches the T/R relays. Hit the foot switch and Tune won't do anything. I work around it by using CW mode and a straight key.
Your problem may be that Tune does not assert Key Out, but I've never checked into that. I'll find out soon because I'm working on a faster T/R switch with electronic amp bias control so that Key Out controls everything. Then I can get rid of the foot switch. 73 & thanks for listening Carl WS7L K3 #486, one year old and still making Dad very happy. > -----Original Message----- > > I'm trying to setup my K3 to tune my tube amp.
