Has anyone had an issue where you can't press in the small knob on the right side on the GTR-200B? When I went to make some adjustments I realized that mine won't press in. If I remove the plastic knob and press on the metal post itself it works fine. I messed with it a little while I was at the hangar last week but I was on limited time and trying to accomplish something else, an quick fix didn't come to mind. Anyone else seen this and know a simple solution?
