Meanwhile it seemed to be, that i found the cause of the distortions.
When i switch the inhousing DSP (from elecraft) in the modus BYPass,
any distortions at the audio are disappeared and i am very happy to
listen to qsos. 

Similary very hard audiodistortion i get, when the DSP switches is ON
and the denoiser is ON. You can read there in the display a message like
this: S1 .nr nt . 

Also there are audiodistortions in low position (less than 9 o clock position 
till zero position) of the AF GAIN, when you can read there: 
S1 nr nt , the same only without the point before the letter nr.

Get anyone an idea, what i can do?
