I made a mistake during assembly of the KX1. I thought during inventory that I was missing a spare screw and a spare washer. That was the mistake. When it came time to assemble the Knob, there they were hiding inside the back of the knob. All else went perfectly. S/N 0186 is up and running. Now on to the tuner and 30 meter kits. Aloha, John KH7T
