S-Meter readings have exactly NOTHING to do with dynamic range, Scott.
This was a discussion, semi-pertinent to Elecraft radios, and that I
offered to take off list and now will. I asked for education about
SDR's that sampled at the antenna connector vs those, like the K3, that
sampled after some superhet and filter magic, and honestly, I'm
learning. There are a lot of really smart and knowledgeable folks on
this list if you just ask questions.
I made an assumption, for the discussion, that my K3 S-meter was linear
[in terms of dB which of course we all know is actually logarithmic].
It was an assumption for the purpose of the discussion, nothing more, to
set up the real question I had, and for which I have since gotten a
really sensible answer. It might help if folks read the entire thread,
S-meter readings had almost nothing to do with it.
I have no idea if my K3 S-meter is accurate above or below S9 and I
don't care, I set it there for 50uV=S9. The rest was an assumption for
the discussion. And thanks to those who helped me understand a bit more
of this.

Since when does the S-meter have anything to do with dynamic range? My
old Kenwood TS-2000 had a pretty tight S-meter, but that didn't help
its, um, pedestrian (to be kind) dynamic range numbers.
