Hi,
When I built my K2/100 the threshold adjustment didn't go right, I turn
trimmer R1 full CCW to get 3.74v on pin5 of U2 (full CW pin 5 goes to 2.6v).
This adjustment is supposed to swing U2 pin 5 fom from 4 to 8 v. I checked
diode polarity, resistor values, everything but never did find
by turning the
AGC on and off and adjusting for no change in the background noise.
