Dave, I don't contest (last and only one was Novice Roundup, 1973) , so I am not familiar with the "mushiness" that's being discussed here. However, I do like to disengage AGC and I also find the extreme distortion to be as objectionable as the harmful high audio level it's designed to prevent. It may be beyond the ability of the K3's DSP, but commercial digital audio limiters, like those found on DSP-based mastering processors, function like a very fast analog peak limiter. As level increases, it simply drives the analog circuit into further limiting. What I would like to see when the K3's AGC is OFF, is to briefly re-establish AGC-F when the AF LIM threshold is reached and remains active just long enough to overcome the objectionable level burst -- then it goes back to AGC OFF. If the K3's limiter is already trying to do this now with brief AGC activation, it's not doing a very good job. It would also be helpful to have the display indicate when the AGC-F is coming active in this mode with something like a "*" or some other special display character that functions as a one-shot in duration. IOW, the special character displays for a minimum of say 0.25 sec so that the action can be seen on very brief peaks.
