SimRangeKnobUp/Down absolutely used to do what I said it did in 4.33 and before, that’s why my binds are the way they are (and have been for probably 3 or 4 versions at this point). Perhaps that was a bug in previous versions, but it did work (doing some digging apparently it WAS a bug that SimRangeKnob* ever caused the AA radar to step).
I’ve mapped SimRadarRangeStepUp/Down and will figure out a work around for the TGP at some point.
