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,
you'll find that the RF gain control will have a much greater effect.
Just a reminder, R1 on the control board is what controls this
threshold, and in the K2 manual, the information relating to this
adjustment is located right next to the info about the S-meter
alignment. (page 46 in my Rev D manual for S/N 3039, so it's probably
the same version as yours).
Hope this helps.

Love this little rig. One slight (mini) probem. Based on over 50 years of
radio operating, amateur, commercial and military I always leave the RF gain
on max for best SNR.
With my K2, turning the control to any position, (max to min and back agin)
makes no difference in gain (Noise) except to shift the position of the S
meter reading, ie, iaw the HI and LO Cal procedure.
Any ideas?
