Hello Ron,
Your AGC threshold has a huge effect on the range of adjustment of the
RF gain control. If the AGC threshold is set too high - meaning that you
are generally operating with very little AGC action - your RF gain
control will have very little effect. If you lower your threshold,
Ron,
The 'RF Gain' in the K2 is actually an IF gain control and it only controls
the gain after the selective elements. All the stages ahead of the IF
amplifier operate at fixed gain levels.
In many receivers where the RF stage is gain controlled, my experience is
that the gain can be made
