Hi Dave,

The AM compression provided in earlier versions was actually an audio 
clipper. Recent tests in our lab and by another dedicated K3 AM user 
showed that it was adding distortion but not "punch." The new code uses 
the MIC AGC system to limit the peak level, and allows more AM 
modulation. We'll be revisiting AM compression in the future.

The IF clipper approach used in SSB is not appropriate for AM.

I'll add this to the release notes. Sorry for the omission.
