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.
