Quick followup… the knobs work fine… I just didn’t realize that the inner knobs need to be first poked, then rotated from way out where the outer knobs are rotated, too. I was always avoiding that area so as not to accidentally disturb the outer knobs. So no real problems left on my list above… some stuff just not implemented, I’m guessing because the radio panel doesn’t match the stuff in the PMDG 737-800… like no TA/RA setting, etc. So I’m just not worrying about it. I’ll go with the mouse to the MSFS panel when I need to turn that on.
