Finally someone who hears what I hear, Im sure this thread will bring out the raving crowd of "mine is just fine". I have the exact same problem in pile ups, and would sure like to see the parameters changed to be able to adjust more to move the threshold higher. There was some attempt to "fix" this some time back but it stopped short of actually working, the agc settings came about but they did not go far enough in the adjustment ranges. Also the audio has been a problem for me for the 3 years I have owned the K3, it is rough or raspy sounding especially in a pile up situation, whether its the audio itself or something generated in the radio that comes out sounding like rough audio I do not know. But compared to my old analog radio it sounds harsh. It is very tiring after a contest. I know all the comments on how nice every ones sounds, mine does not, and apparently I am not alone. And no I am not bashing the K3, its my radio of choice, I have tried every setting and every "trick" suggested in the past 3 years and cannot get a satisfactory outcome on audio or AGC pileup management.
