Juhani, I've encountered this as well. It's particularly noticeable with some of the wide ESSB sig's which tend to use less compression and no doubt have a higher peak to average ratio than most other signals on the band.
I've found that reducing the RF gain control to about -10 to -12, helps quite a bit. For me, the granularity of the AF gain is too coarse. Sometimes, even a setting of "1" is too much when I'm wearing headphones (depending upon the particular phones). For that reason, I reduced the RF gain, and in so doing discovered the side benefit that itsignificantly reduced or eliminated the distortion you mention. 73, Dale WA8SRA > The firmware version in my KX3 is MCU 02.33, DSP 01.33.
