The drive level meter has a long bar with a separate rectangle to the right of it. I can increase my drive (digital modes using DAX) so that the rectangle goes into the red of the scale but remains yellow. Is that a Bad Thing © or does the distortion start when the rectangle itself turns red?

OT: Ping FRS. It is very difficult to fine tune settings in DAX using the mouse, and for some reason, keyboard control is not enabled. Need finer control as a unit or two change up or down on the TX gain has a significant effect on the output.

Keep the peak square on the audio input meter from going into the red area at all, not just the bar.   Also, use DIGIU or DIGIL so it bypasses the processing and shallows the filters to reduce latency.
