[Elecraft] About the K3 cw speed

[Steve Ellington]

I believe you are referring to the addition to the weight menu item in 
config. You can choose between old and new versions. It has no effect on the 
cw character distortion I'm referring to. CW sent at over 40 wpm by an 
external source comes out with varying dit and dah lengths and irregular 
element spacing due to sluggish switching. At 65 wpm you can record and play 
your transmission back at 32 wpm and easily hear what I am talking about. 
Instead of the perfectly formed characters normally produced by a keyboard, 
it comes out sounding like a BUG. You can hear this without actually 
transmitting by using test mode and listening to the sidetone. However,,,,if 
you push the XMIT button, all is well and cw sounds fine.
