My Icom 746 suffers the same problem. I had hoped that the Elecraft K3 that I had in mind would solve this issue for me as well but maybe not. The review in QST was the best they ever gave but maybe I hope for too much.

Because of this phenomenon, when I purchased a new rig, I looked for one that could have AGC totally off (when needed) and one that can employ narrow DSP filtering. I must say that I have not really solved this issue . I can see a marginal difference with AGC turned off but strong signals still essentially desensitize other stations in the waterfall. The DSP features do better and I can get rid of the phenomena by turning to a narrow filter. However this does not help if the offending station is with 300 - 500 Hz ( a lot when dealing with narrow digital modes). Does anyone have any advice on how to once and for all solve this issue?
