I think a lot of the problems we hear on the air with folks using bugs
is contact maintenance.  In the video, he clearly had taken very good
care of his keys and contact problems were not a problem.

Keying my K2 or K3 with my Lionel J-36 works just fine.  Given that all
mechanical keys bounce, and I know I'm keying a CPU, they must have some
good conditioning there.

Fred, just for the record, if you look at my Youtube video you will see 
a little green box above my K2.  That holds my "bug descratcher" from 
Jackson Harbor Press.  It eliminates 'contact bounce' by chopping off 
the first 10 ms of each character keyed, and then adding 10 ms back on 
the end of each character.  It only cost $9 and it works with bugs, 
straight keys, and 'swipers.  Plus, it's got a solid state relay so I 
can safely key my tube rigs with it also.  Of course, I still treat my 
contacts lcarefully and recently installed brand new ones in my 
Vibroplex.  Not inexpensive but clearly worth the cost.
