That has happened to me, too. I think it's because the AF amp has a lot of headroom, especially if config af gain = HI.
There is an AF limiter setting: config tech md = on config af lim = 20 (adjust to personal preference) I operated my old TS-850 with agc off on cw, but can't really do it with the K3 without riding the rf or af gain control. Loud signals either hurt my ears, or hit the limiter, making them sound like mush. I operate the K3 on cw with fast agc, config agc slp = 0, config agc thr = 8. That seems to work well for me.
