[Elecraft] K2 Fast QSK

[Don Rasmussen]

Hi Guys,

The K2 QSK seems to work up until 16 WPM with K2
#3312. That is the highest speed where the receiver
does not mute in between dashes when sending the
number zero. I'd like to improve on this.  

Gary S. suggested:

You can try shortening the t-r delay muting by
reducing R17 in the Q6, Q7 mute circuit from 3.3M to
something smaller. Try tacking another resistor of
3.3M across the existing R17 for example. If the delay
becomes too short, then you'll hear too much of a t-r
transition "pop" and you'll have to use a larger
value. Use a 0.00 t-r setting.

Has anyone else tried this, and come up with an
optimal value that I might use as a starting point?

Thanks,
