Hi Dave, Yes, you would think that auto mode is probably the best to be in, but it's not. Once you have the tuner "trained" for the operating frequencies, put it in manual mode and leave it there.
That's what I did and continue to do, and I've had the KAT500/KPA500 combo for quite a few years. 73 de Jim - KE8G On Sun, Mar 24, 2019 at 3:34 PM <[email protected]> wrote: > I just received a new factory built KAT500 a few days ago. > > I am using it with my K3 and KPA500 cabled with (2) E850463 Aux interface > cables as in Figure 1 on page 5 of the KAT500 manual. > > I have recently updated the firmware on both the K3 and KPA500. > > > > I am running about 250W on FT8.
