Hi, Somehow my K3 on 20 meters when I turn VFO A, VFO B follows. I have looked up what to do and from what I have read, if I hold the "SUB" button (between the 2 VFO knobs) it is suppost to turn it off but it isn't. In VFO B, the decimal is slowly flashing so I know I have them linked. I have no idea how I did it and how to stop it. -- Thanks, Fred
