Wow. Sounds like as much fun as a cell phone. No thanks.
No DSP is ever going to match my preferences AND your preferences AND
everyone else's preferences. Heck, we can't even agree on what
"proper" AGC is, so Elecraft has given us the controls to set as we
see fit.
Different strokes for different folks. Always has been, always will be.
