Hi Tom, On the K4, with full QSK selected, you can hear between dots at 40 WPM. There's no need for a "QRQ" mode, as on the K3, because the K4 doesn't have to update a synth between TX and RX. Wayne N6KR > On Jun 11, 2020, at 11:51 AM, Tom Doligalski via Elecraft > wrote: > > I still do

Not being  a high speed CW op nor a contest CW op, I find that QSK is, well, just very nice.   I don't need to hear between the CW elements, nor even the letters, but more so in between the words.   Some ops have  a clean fist but run all the words together.  No spaces.  Drives me nuts.

I have always felt as K9ZTV does. I don't mean to speak heresy here, and I would never deny anybody's right to use full QSK, such as when chasing DX. However, I have never felt the need to hear between dits. Between characters or words seems more than enough for me, especially at the CW speeds

Really interesting, Vic. Here's a minor point: Instead of measuring to the "first whiff" of RF, I'd probably measure to the point of 90% of max RF value. This is because the rise time of a pulse is usually defined as the time to go from 10% to 90% of the final (peak) value.  Congratulations on
