After a couple of hours in the manual, I give up. How come I have my K3 changing A and B with main A VFO control. I don't remember that happening. Also, I notice that I can change the B VFO display with the B VFO knob - ! Bet I tapped a button by accident but can't determine which one and how to turn it off. Thanks and sorry for the bother.
