Flex Drivers Report please

[WA1GFZ]

You guys running Flex radio systems how about some information.

My question do you ever see the sound card go into saturation blowing out the spectrum display. The Fix of course is to reduce gain or switch in the attenuator.
Do you guys ever suffer from poor mds when you do this. So do you ever get to a point when you can't hear a weak signal in a busy band full of strong signals?

I have measured my SDR which is very close to the Flex design. It has a very wide dynamic range. Much wider than a sound card. These gain and attenuators help the radio by shifting the dynamic range around. I wonder what you guy have seen on various bands.
