After reading Don's (W3FPR) AGC procedure, curiosity got the best of me.  I set up my parameters as he stated and was surprised to find a considerable difference between AGC ON and AGC OFF with AGC OFF being considerably louder.  I am going to remove R1 (71K) from the Control Board and substitute a pot to find the proper resistance value.  I understand this pot should be adjusted to where the AGC ON and OFF should be just about the same with the RF gain set fully clockwise.  If I remember correctly a 100K pot should be used to establish the value of R1.  Is this the correct procedure?   Roy Morris  W4WFB
