The legend [urban or otherwise] is that the code began, he calmly sat down at the mill, lit a cigarette, took a couple of puffs, and then started pounding the keys. The legend further states that after the run finished, he was still pounding the keys for some time [3-15 minutes ... 74.34 percent of people make up their own statistics so who knows]. That he did make record copy at that speed is without question, without the embellishment. That the record hasn't been broken since suggests to me that it may be getting close to some physical limit. Ted went on to found a company manufacturing keys and bugs of some fame.
I'm kind of with you Tom. I can make solid record copy at 25 WPM or so if I don't have a glass of wine with dinner just before sitting down at the rig. I can converse pretty well at 30-35 in my head, writing down only notes. I can contest at D4B/C speeds so long as he doesn't send me very much and I have a pretty good idea what it's going to be :-) Real conversation ... one which involves questions and meaningful answers ... at 100 WPM or above is something I'd like to see. I'm not from MO but show me. I watched the QSK keying waveform from my K3 [#642] on my Tek scope sending just a string of dots. It stays "good" based on what QST publishes in product reviews of "good" keying up to about 50 WPM. Above that, it began to look "squished" in time, and at 60 or so was pretty square, somewhat uneven in time, and was sounding fairly rough in the monitor rx. I think Elecraft says 45 WPM max which, since they seem to be a crafty bunch, would assure meeting their specification. 73, Fred K6DGW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
