[Elecraft] K3 TX delay

[Bill VanAlstyne W5WVO]

... Which (QRQ mode) unfortunately isn't available, in practical terms, in 
the absence of the KRX3 second receiver, since working split or XIT is 
impossible. What a wonderful experience using this mode is, though! If only 
I could use it for chasing DX running offset pile-ups. Really justifies 
having the KRX3. It's on my must-have list, but a few other things have to 
come first. :-(

I've also advocated to Elecraft in the past to make available RF delay 
settings below 8 ms for those of us who have fast QSK amplifier switching 
using vacuum relays or switching diodes. (My homebrew 6m amplifier T-R speed 
is well under 4 ms, for example. The new Elecraft amp, I assume, will be 
even faster.)

I'd also like to see the CW WGHT parameter (optionally) configure itself to 
conform to the amount of RF delay selected in concert with the speed 
selected for the internal keyer. Right now, the default CW WGHT value of 
1.10 is optimized for a QSK RF delay of 8 ms (default) and a keyer speed of 
20 WPM. (Do the math.) However, an ideal CW WGHT value could easily be 
computed automatically from these two parameters, giving you the best-shaped 
CW elements at different sending speeds, on the fly. (Of course, such a 
feature would only work when using the internal keyer, not an external 
one -- unless autodetection of CW sending speed was also incorporated.)

No, you can't change this, but the best QSK performance comes from 
activating QRQ CW mode.
