Speaking of w6hlh, I saw his name in silent keys in qst a few months back.  

Yes, k6kps in Los Angeles supposedly got across the high voltage in his amp.  

There was another guy, wb6gtc I think who was at his rig one night and tried to prop his foot up on his amp.  Well, he missed and became an instant silent key.  

And then there was w5tbn who's own phonetics I won't repeat here who used to call cq Ardmore Oaklahoma in the middle of the afternoon on westcars and a 
few other places.  He was in Garden Grove California at the time.  

But at least you could move off a few KHz from any of those guys and still have an intelligent qso.  It's a different story with repeater jammers.
