Regarding your last sentence, to my knowledge, Elecraft is the ONLY
manufacturer who does not allow adjustment of CW Rise/Fall time (Ten-Tec,
Yaesu and possibly others do).  Adjusting this time to less than ~5ms can
cause clicks which, as you said above, can be useful in contests to keep
others away from your run frequency.  

Kudos to Wayne for not allowing the user to adjust this parameter and
therefore keeping our K3s cleaner than other rigs.
