... 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.)
