There is also software to allow you to use ICW, Internet CW. ICW allows you to participate in QSO's, roundtables and club nets, when the bands are down. By the way, CW at 100 wpm is often mistaken for some sort of digital mode transmission, as you'll see, if you listen to the recordings on the website.

Dana Thanks for showing us this site. I was particularly interested in the article regarding neuroplasticity associated with learning Morse code: I thought you might like a note in a similar vein. My old friend Stuart Kind G4AYP (sk) was Director of Forensic Science here in the UK and he was of the opinion that reading Morse code was good for the brain. He listened to 40m Morse QSOs in French and Spanish while settling down to sleep, he told me. This is an article about him if you care to know more: http://www.telegraph.co.uk/news/obituaries/1428695/Professor-Stuart-Kind.html It doesn't even mention his fondness for amateur radio - he was often heard on local nets and would join ham friends and I for a drink at a local pub.

Re: [Elecraft] K3: QRQ high-speed QSK
Please get this correct! He did not copy at 200 wpm. He copied one call sign at 200 wpm, but copying code and/or having a QSO at that speed is a completely different situation.

Re: [Elecraft] K3: QRQ high-speed QSK
Almost always he could hear my first break attempt. We went up to 75 wpm and he could still hear my bk That's good to know. Of course if it was pre-beta as you mention, changes in firmware by release date could throw this off, but it's still encouraging. So, we are wondering about what is going on concerning this thread. It's not just about hearing the breaks -- it's also how good the K3 sounded at those speeds. W5UXH pointed me to some recordings of tests by N4LQ and I have to say, even if things weren't perfect, I didn't hear anything too objectionable (granted, I was very tired, listened to only a couple samples, and briefly). I've had a couple ops offer to let me hear some on-the-air tests and I'll take them up on it. What may be acceptable performance to a casual CW op or to a contester may not be acceptable to a QRQ QSK guru. At the same time, it's understandable that reworking the K3 to achieve guru-level CW performance at this stage may be in the best interest of a niche group of ops but not the company or the majority of ops. While I still feel that it's a shame to not achieve solid performance at speeds pushing 100 WPM on a modern, high performance rig, for such a basic and fundamental mode, I have no doubt there are tradeoffs involved and that the designers are focusing on putting their money, time and efforts on what most ops will consider most important. Thanks for all the great responses in this thread. --Andrew .. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: QRQ high-speed QSK
A breaking station sounds like a clicking sound instead of a tone on the K3 at speeds over 30-35wpm but at least it can be heard. The main problem is with keying irregularity. Yes, the dits are a bit short but that can be compensated for. The real problem is random variation between characters. For example, at high speed, an H could end up sounding like SE. It really strains the receiving op to interpret what you're trying to say.

Re: [Elecraft] K3: QRQ high-speed QSK
While it's gracious of you to give the K3 the benefit of the doubt in the hands of QRQ QSK gurus, I'm also not convinced this is a true failing of the K3, if it's true (my K3's dits sound ok to me at 50wpm full QSK, tho slightly shortened). In fact, compromise is a hallmark of good design. The hardware limits that Guy talked about earlier are real so you have to be accommodating in those regards if you're going to do the entire radio right. Putting it another way, one would have to wonder what other things have gotten short shrift in those radios that do somehow manage to do full QSK at 100wpm cleanly. If it's the 7700, the rest of the RX performance in more useful areas is easily exceeded significantly by the K3. If it's the 7800, the K3 still exceeds many of its capabilities and at about 1/5 the cost. I will say I'd be slightly more concerned if QRQ performance wasn't good in semi-breakin mode. That would be a more legitimate gripe - has anyone assessed the K3 at those speeds in non-QSK mode? Like I said, I only have the ability to make 50wpm with the built in keyer (cocoaModem can go faster but it's operating mode is J2A) so I don't know how it does above that. I'd personally kind of put this around the level of the QRP threads and maybe a little above the knob threads. Not overly impressed. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-QRQ-high-speed-QSK-tp5057956p5059248.html Sent from the [K3] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: QRQ high-speed QSK
I am not sure if this has been mentioned yet, but another setting that may have an affect on this is switching between New QSK and OLD QSK by tapping 3 under the CW WGHT Menu Item. I think that the default is New. I believe Old is supposed to provide better QSK performance while New reduces keying artifacts. 73, John Toby Pennington wrote: A friend of mine and I experiminted to see if the K3 could hear a bk during a transmission at high speeds He was using the K3 with a pre BETA version, and I was on a Icom 7700.

Tom W8JI wrote: Who the heck is copying that and what are they copying??? The highest speed record for a long time, of copying unexpected text, was only around 70-80 WPM. That record held the whole time I was growing up, and it was from the 30's I think. It is certainly impossible to copy 300 WPM without decoding. I have some nagging questions about these speed claims. Ted McElroy @ something like 74+ WPM back in the early thirties I think, I could Google it I guess. 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: QRQ high-speed QSK
Honestly, that is the first time I have heard that. Obviously did not see the memo. Back to OLD QSK. Hurray. Need to spend time doing more random word searches in the manual. 73, Guy.

[Elecraft] K3: QRQ high-speed QSK
Until Tom said I can't use my CW pulser with the K3, and now I know why., I would have said: Use an external keyer (such as the Super CMos from Idiom Press) for your tests. Real men don't use built-in keyers. And don't mistake the 'sound' of 100 WPM for a slowed-down version. It ain't the same.
