[Elecraft] Problem with K2 transmit quality

[Giulio Pico - IW3HVB]

I have a problem with a K2 who behaves strangely on cw. The note is very 
bad, full of distorsions (rf?) but the Tuning continuous carrier is 
crisp and clean.....
I don't know if the two are related (I suspect that.... :-)  ) but tah 
would point to the key !?!.
The other odd thing is that on SSB the modulation is hopping 
continuously from very clean and rich to very compressed.....

Any clue?
