" I also ran into an article on how to soup up the receiver by
changing the
cathode bias and the screen resistor of the second IF so that it would be
the same as the first and third IF. I haven't tried it yet, but I will one
of these days. The author of the article, Phil Atchley, KO6BB claims that
AGC action, especially on the higher bands is improved."

I also ran into this article, but on my receiver, which is a later
model, I could not see clearly what he meant. Perhaps the design
changed in the later versions, because it seems to have plenty of gain
to me. If you happen to figure this out let us know.
