[Elecraft] ALC control of W6PQL amp from my K3

[Dr. William J. Schmidt]

The underlying reality is that if you analyze the input-output transfer function for a linear amplifier with ALC, the resulting transfer function is not linear. Thus you would expect all sorts of odd behaviors as the function changes order when ALC engages. Simple math.
