I've made multiple recordings and I had Eric make recordings of a 60
over S9 AM station. I am unable to duplicate what you are seeing.
What I need for diagnosis of the issue is an IQ recording so I can see
the problem in action. This will be a large file that probably won't
fit through

Look like you found the fix. The AGC was improved in the 1.18.x

A point of interest. I am able to stop this audio limiting effect
on AM by reducing the AGC-T control from the nominal setting of 90
to 60 and below, depending on the strength of the RX signal. This
was unnecessary previously in 1.16.2
I responded some time ago to this subject, saying that I didn't see any
problem with my S-1000; since the topic continues open I though it
twice and made some test before giving more opinions.
Listening carefully to strong (and not so strong) AM voice
transmissions, I must agree that the
Ignacio, all:
Your observations are consistent with mine. My point of reference is a
new Pwr SDR 1.18.0 with a F5Ka, compared to Hammarlund and
Hallicrafters non-coherent AM detection (Hammarund wins, by the way).
The F5Ka coherent AM detection is quite impressive in terms of its

Audio limiting on AM and SAM receive very evident in the new release, just like
it was in the previous release 1.18.0 with the SDR-1000. This issue started
with the SVN test branch, SVN 2797 when the changes were made to the AGC.
