Gerhardt,
If you still have a difference between AGC on and off at 3.65 volts or
lower, I would hesitate to go further, but you certainly can try it and see
what happens - no real harm will come from a lower threshold voltage.
After setting the threshold, then adjust CAL S LO first and then CAL
OK,
I did it for several modes and there are differences which I will leave for
now. Aimed for 3.65 volts at U2 now. Result seems satisfactory to the ear.
Today in the evening we will use a signal generator and a variable
attenuator to test sensitivities of my K2 and this other one.
