[Elecraft] [K3] Phase Noise / CW Key Clicks

[Matthew Zilmer]

Yep, I was finding merit in this choice of action.  Allowing the adjustment of rise/fall timings  into key click territory should be discouraged.

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.
