[Elecraft] Audible thump sound when sending cw on K2

[Don Baucom]

I noticed when I send CW in addition to the sidetone there a thump sound that
I hear on each character or almost each character. It is not noticed on 40
meters. I can hear it some on 20. I hear it more on 12m and then it is the
strongest on 10 meters were it is very noticeable.

I don't hear it in the test Mode

Any Ideas?
