There are guidelines on my website www.w3fpr.com for how to set the
K3/K3S AGC Threshold and Slope for best results.
See the "Noisy K3" article.

Scott,
If the weakest signals are already activating the AGC, that's the exact
condition that leads to the many 'my K3 is noisy' complaints that we see here.
Plus, that tends to make all signals sound like they're the same strength,
another complaint we've heard in the past.
In fact, you don't want weak signals activating AGC. You want strong signals,
above a certain threshhold (AGC THR on the K3) to activate it.
This gives you a nice, quiet linear region where weak signals sound weak, and
stronger signals sound stronger.
