Hey Joe, Thanks for the fast reply!
No, I do not have the AGC Off, nor have I changed any of the "settings" within the AGC (Menus). I should have stated that in my original post. Anyway, I am really stumped as what the problem is. If you happen to have a K3 equipped as mine, could try to listen to an AM station with the "Volume" turned up, to see if you are receiving the distortion? I should have been more specific, the radio is totally loaded. It does have the 8 Pole filters in both receivers. From my recollection I have the following filters: 250 Data & CW, 2.1 for SSB, 2.8 for SSB, and 6 for AM, and 13 for FM. I hope this makes it a litter clearer and not more confusing.
