Ahh, OK! No most definitely not DCW -- just a nice "modulated CW" sound which comes when I key both HF rigs, which have different side tones. I can't remember if I did this live on the air, or off air... was a while back now. Yes, CW is about timing, I guess those of us who can QRQ since we have split second timing and reflexes, but also there is recognition of rhythm. Pure "perfect" CW does have a special timing to it, and you will hear it on good DCW programs indeed, but we also used to hear it from Coastal Stations doing weather reports and traffic lists, which used not a computer but a punched tape. Once you listen to that a lot you get an exact feel for the timing. In fact if you listen for hours on end, it really starts to send you to sleep. I used to copy down bulletins and have micronaps while writing then wake up split second later. I also could sleep fully, leaving the RX on and awake if I heard my callsign, just as you may wake when someone calls your name. I guess not when in the deep sleep period though. Yes in this repetitive CQ I got into that rhythm of "perfect CW" and it's hardest on the bug, but really easy on the straight key, and of course a cinch on the paddle. But I was trying to show off in jumping between the various keys in mid flight, and this was the hardest thing, and you can see I slipped up several times because each key has a different keying technique of course. I should re attempt this with the side swiper, that will be really difficult as I'm new to that key, and I haven't yet tried "perfect CW" on it, preferring to use smaller internal gaps, as is the norm on side swipers, though one can overcome this by giving the hand a wider swing and not using it close up. 73 OM
