Hello,
What is the problem? My ssb-transmit has distortion on 10m. The other bands
are ok. I have no mods on ksb2.

If it's on one band, it's usually RF getting into the audio circuits on that
band, most commonly through the microphone connector.
One other thing that could be a factor with the K2 is that on 10 meters the
output is usually the lowest, so it's just possible that you're over-driving
the rig with audio on that band to make full output.
Are you using an external mic preamplifier? That's a common source of both
RF feedback into the audio and for enough audio to over-drive the rig.
Even if you have no audio preamplifier, the possibility of RF getting into
the mic is the first thing to check. The easiest way to do that is to switch
from your antenna to a good dummy load and compare your audio on a monitor
receiver.
