Whoops - the "upward shifts" I was referring to are noise floor shifts

But this is not a fix, it is a bandaid. I need an IQ recording of
the problem happening. I am unhappy that Frank is having to set the
AGC threshold to a pretty ridiculous level. What this says to me is
that there is something wrong with attack and it needs to be
investigated.
I am very proud of SAM/AM so I don't want it to have problems like
this.

Look like you found the fix. The AGC was improved in the 1.18.x
releases so this making this parameter change is very reasonable.

Subject: Re: [Flexradio] 1.18.1 Audio Limiting
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 and earlier.
