Al,
My understanding of the hardware AGC is that it is fixed and is not
dependent on the menu AGC parameters. The AGC THR and SLP are strictly
DSP parameters.
The Hardware AGC is there only to protect the ADC from overload due to
strong signals.
There may some variation in the exact level
This would be easy to test. Normally, 'hardware AGC' kicks in at an input
signal level of -46 dBm or so. This point is essentially independent of the AGC
THR and SLP settings. See if your K3 varies from this data point anomalously.

Personally, I wouldn't go so far as to say the radio performs correctly. Without
writing a long history, let's just say that I discovered this RF gain issue 8 or
9 years ago. I demonstrated it to an Elecraft engineer in my shack who had
brought along his fully up to date K3 which we compared.

My concern would be "does the S meter indicate correctly?"
Thus with 50 uV applied to the antenna input it should read S-9, and
with 0.78 uV applied it should read S-3, and with 5000 uV applied it
should read S-9 +40 dB. I've checked my K3S at these and other values
and I'm confident that t
