Poor receive, Ranger/Galaxy radio chassis, acts like no AGC

I have two radios that I have been looking to repair. The first is a Lincoln II that has poor receive that I tricked into performing fair by substituting some resistor values around the op-amp AGC circuit. I thought it was a poor rf amp transistor and replaced that small surface mount device and it performed the same. So onto the next radio, a Connex General Lee. I have been through a few of them looking at the 4 to five diodes up to the modulation circuit and been stiffed in the past. What and where do you think I should start on this one? I am looking at a different approach and would be interested in bettering my skills.
