[Elecraft] K-2 Transmitted signal distorted (Hum)

[Greg Storms]

I have just started experiencing a tremendous distortion on my 
transmitted signal (K-2).  It was first noticed by a SSB
contact.  He said my transmission was strong but nearly unreadable.  I 
duplicated it at low and high power on a separate receiver.
It occurs on both SSB and CW.  This happened rather suddenly as I had 
contacts the previous day with no problems noted.

Occurs when the KAT-100 is grounded or ungrounded and on different 
antennas.  Anyone else had this happen?  Suggestions
as to where to begin looking?

Thanks in advance,
