[Elecraft] K3 Beta Firmware Rev. 4.03: "CW+" mode (Ultra-fastbreak-in; VOX-CW up to 100 WPM)

[WILLIS COOKE]

Drew, you have been watching the lady operator with the long finger nails on the Night-of-Nights Utube video too much.  You don't need all that hand waving and finger motion to send with a bug!

I was not complaining about the K3 QSK+ or requesting that Elecraft do
anything at all about this.  Merely commenting on the curious effect
(because it is the dit contact on bugs that is typically screwed up;
not the dahs). 

I noted that it was a matter of technique, and I've found that I can
reduce the dah 'tick' entirely by keeping my index finger on the
paddle instead of "slamming" it like you do with the dit side.
Actually, I think this may be better bug technique in any case because
it is only the dit side that you need to inject the kinetic energy
into. Eliminating the unnecessary finger travel on the dah side might
allow greater speed (if I can get used to it...)

Yes, you can use a bug in normal QSK mode perfectly well for all
intents and purspses. But the QSK+ mode does sound better, even at
non-QRQ speeds.

73,
