[Elecraft] K3 goes deaf when set to 12W or more

[Bob McGraw]

Secondarily, this sounds like all of the station equipment was not 
properly bonded to a common point.  And, likely any outside ground was 
not bonded back to the AC Mains ground as specified by NEC.   Refer to 
the ARRL publication Station Grounding and Bonding by ARRL, Ward Silver.
