Please explain to me where this non-linearity is generated. If 1 volt of RF
(really I-F) gain reduction causes 10 dB of gain reduction, prey tell what
difference does it make if the 1 volt is generated by an AGC circuit or a manual
control? Either way, *all* signals are reduced 10 dB. What's non-linear about that?

What are your AGC settings? I have a K3 with the new synths and I use almost
the least AGC possible ... THR = 12 and SLP = 000.
AGC creates non-linearity, the non-linearity is most pronounced at the signal
level where it kicks in, and non-linearity creates mixing. Do the math for
the sum and difference frequencies when you have multiple signals very close
to each other within the receive passband.
