Yes. In my discussions with John, he told me that the "ACG Bias" adjustment R1127 (A.K.A. "AGC Pedestal") is basically not used, being left as set in the instructions (fully clockwise). The IF gain pot is actually used to set the AGC pedestal in this scenario. I've tried two or three alternate procedures, both of my own and other's devising, but once I understood what was going on the "book" method seemed to work the best. There are two sections, coarse and final adjustment. If things are "pretty close", coarse probably does not need to be done. 73 -Jim NU0C -- The universe we're in will reach absolute zero in three hours.
