Re: [Elecraft] Elecraft Digest, Vol 73, Issue 15 - message 7 - using /QRP in contests
This triggered the recollection that /QRP as a call sign suffix is illegal (ie contrary to license conditions) in UK - certainly clubs like GQRP FISTS UK pe remind us of that from time to time, Regards George - G4TPV -- Message: 7 Date: Thu, 13 May 2010 11:28:15 -0400 From: Guy Olinger K2AV olin...@bellsouth.net Subject: [Elecraft] Using /QRP in CW contests To: Elecraft Reflector elecraft@mailman.qth.net Message-ID: aanlktinxeyunmknxhsd7bz4zj21lxn4blsl3x6p89...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 Since we have so many QRPers on this reflector... Each to his own in how they want to identify themselves in casual operation. But if you use /QRP on the end of your call in a CW contest you place yourself at an immediate disadvantage beyond your choice of power levels. If you are going to call running stations, please don't put /QRP in your logger's call sign field. Stick it in your CQ string if you put it anywhere. Even though I've made over 2000 40m Q's multiple times in ARRL and CQ DX tests, and you can't do that if you don't copy 90% of calls right the first time, I rarely can copy a call sign in the form prefix/callsign correctly the first time, even if it is loud. My mind is simply NOT EXPECTING it. I do better with the trailing form callsign/xxx *IF* and only if I cleanly copied the callsign before the / . If the signal is in the noise, and I don't have the front of the call, /QRP is just confusion. Further, the longer calls are, the harder to copy. Worse, often a weak station will be copyable ONLY on the VERY TOP of QSB peaks, lasting only for a few letters. Anything you send that isn't your call sign hurts your chances -- adding spurious P,Q,R to the letter soup I am trying to construct a call from does NOT help. And if I hear a / in there you can bet I'm trying to construct a leading extra prefix that doesn't exist. Thank you for your assistance... EVERY contest there are a few stations where the ONLY part of the callsign string I got cleanly was /QRP, and they did NOT go into the log. I can't send them an email to explain how they hurt themselves because I don't know who they were The only thing I know is that /QRP is part of the reason I didn't copy them. BTW, note that I do NOT consider QRPers a nuisance to be put up with in contests, quite the opposite. I really try hard for the weak signals. Those are the ones I work that maybe nobody else can, and that is score differential. So bring 'em all on. Please just don't send /QRP after your call. Tell your QRP friends. 73, Guy.

Andrew, I can't begin to key at 45 WPM so I have not responded. The best I can copy call signs in contests is around 50 WPM and the K3 sounds fine to me at 50 and I don't have any complaints using a WinKeyer USB.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
Just out of curiosity, why would one need full QSK at those speeds? By then the characters are so fast that, seems to me, you could use a short enough delay to keep from T/R switching between individual dits and dahs but still have QSK for all practical purposes between letters? I'm like Cookie in that my sending is still poor enough that this won't be an issue for a long long time. Tho ironically I'm now better with my vibroplex bug than with my bencher. And actually having to decide which one I'd rather put the lions share of practice into at this point, hihi. But that's a seperate story. My copy speed is still only between 25 and 30 wpm, tho I can handle contest style exchanges and very plain/basic language at around 35. So I'm well well away from this with QRQ QSK ever becoming an issue for me, but am still wondering? 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/How-is-K3-QRQ-QSK-performance-50-100-WPM-tp5048269p5051096.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] How is K3 QRQ QSK performance 50-100 WPM?
I tested QRQ CW using SpectraVue to display the dits and did not rely on my opinion of how it sounded. Above 45 wpm, the dits are of random length which makes copy difficult for those people who normally copy above those speeds. I used both Winkey USB, the K3's internal keyer and an external keyer. Using semi-QSK, QSK mode or even Test mode made no difference. The problem has something to do with the rig's CPU capability. What got me started on this was during a QSO with a friend at about 50 WPM. He had a sharp ear and informed me that something wasn't quiet right. Since then, I've kept my speed below 45 wpm and suffered with the slow QSK at 30 wpm and higher. Otherwise the K3 is the ultimate rigFor some things.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
I don't have any inside knowledge about the internal design of the K3 but we all know that it is computer based digital. With any CPU based system there is a limit to the speed it can handle signal processing while continuing other required tasks. I would think that the task of upgrading the processor speed or improving the code efficiency for unlimited code speed would be an essential redesign of the transceiver computer section and would benefit only a very few. If you need SpectraVue or some other special device to find a defect then in my opinion the defect is not worth complaint. With two and a half years of reading this reflector, this is the first time I remember this subject being discussed. The fastest code that I have heard on the ham bands is about 50 WPM and that is really rare. I am convinced that there is some limit to the code speed that the K3 will handle, but I am also convinced that it will never be a problem to me.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
it is not necessary to use special equipment to hear the problem - if it is present. Sorry but I hear if a dot is too short and is missing 1/1000 of a second if the signal is strengh enough. It is always the same discussion - only a few people can judge about CW speed, and only these people know what's going on in the scene - but lots of guys continue writing how unimportant this problem must be.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
I will continue to collect more skilled feedbacks on the bands. QRQ performance may be different between the K3's internal keyer and the use of an external keyer. It's been a long time since I've conducted any tests and those tests were completed many firmware revisions in the past. As I recall, certain timing attributes may be more accurate when using the internal keyer since the K3 can look ahead at the WPM setting -- something that cannot be done when using an external keyer. Wayne and Lyle probably have the best information concerning the differences between the internal and external keyer QRQ speeds. I would give them an opportunity to reply after they get back from the Dayton convention.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
I am just guessing on this, but ... As I understand it, the K3 has quite short rise and fall times (about 2.5 msec) on CW with carefully shaped (i.e., CPU processed) corners of the waveform to prevent key clicks. The faster the CW the more often the CPU is required to process the signal, and it wouldn't surprise me to learn that 50 WPM was a practical limit based upon some ceiling that Elecraft set for CPU usage for that task. At speeds higher than that the wave shaping routine possibly becomes unreliable, and dit length maybe even becomes erratic as a function of their frequency of occurrence (a b versus a c, for example). As I said, that's just a guess on my part but it seems like a reasonable guess to me, at least until someone from Elecraft comments. 73, Dave AB7E On 5/14/2010 8:59 AM, DK4XL wrote: it is not necessary to use special equipment to hear the problem - if it is present.

The cable option for the Kenwood is plug and play for the K2 and K3 radios. The K3 is simple to configure for the microphone. I started with two TX audio equalizer settings, one for the dynamic and the other for the HC-5. I also have an older Kenwood mic with the HC-4 that was used during initial testing on the K-3. After a few months of trying various combinations of equalizer, mic gain and compression settings, I came to a final arrangement which I only use. Over and over, it is reported that my audio sounds super. The settings are: Mic gain=20, Comp=24, TX Equalizer= flat with 6 dB boast. K3 Config= Mic Low Z, Bias off The broadcast mic requires different settings but it wasn't ever close to the HC-5 for best fidelity and “undistorted” punch. The HC-4 is almost the same but lacks fidelity. Each user should experiment a little to match your own voice characteristics. After 18 months of use my K3 still measures up to all my expectations. 73, John, W1QS s/n 2274 __ 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 Link to QRQ CW RECORDING
Well, yes, I can hear that, barely, in the recording, but at 45 WPM? And that doesn't sound irregular to me, it sounds shortened. Add a little weight to it. Hate to say it, but ain't this started off in the direction of the Princess and the Pea? You DID have to run it slow to make it apparent. The real problem is that by pushing that speed you are working against the absolutely pure, artifact-free, soft QSK that everyone seems to want, along with all the features that pull CPU time away from state changes. AND we are talking about resource- and time-constrained HARDWARE code, the most difficult kind of coding on the planet. AND from a company that doesn't have the resources to spend on a couple hundred salaried programmers and testers to work on it. The degree of tricky I don't believe can be appreciated by anybody that hasn't written and debugged hardware code in a production environment. You guys are really lucky that Wayne appears to enjoy such stuff. Hardware code is seriously deranged work. The alternative is guess who, and we all know how that has turned out for innovation and RX performance. I got the K3 for the RX, and if he ever does manage to do artifact-free 50 wpm state changes with RX between the dits and microscopically perfect CW shaping, then bully for him and I owe him a few rounds somewhere. But reality beckons... Get your KPA's and P3's and other stuff out there to keep up the revenue stream so we get to keep this string of innovation some take for granted. That off my chest, I'm in favor of an option for those of us that would rather have HARD QSK instead of the squeaky clean, absolutely no artifact QSK that so many seem to want. I had 60 wpm QSK, clean between the bauds, with a tube electronic TR switch and a separate RX, TX (SB 300/400), and an AGC and audio gain clamp circuit added to the RX, driven off the TX key circuit, and you could hear between all the dits at 60 wpm.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
The other side of this coin is that many K3 owners probably could care less about this and are much more interested in other issues/enhancements. I could care less if this ever got on the radar screen as far as features are concerned. If it's not there yet, I hope it never appears.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
I wonder how many radios in the world would ever be used at 50 WPM or more? Then I wonder what would have to be added to the cost for every radio, or given up in other performance, to get there.

[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.

Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM?
Hi Guy That would be a very useful option. The 2 tone oscillator is not that useful although a welcome feature. The ability to set 2 different duty cycle rates would also be great. If you had the choice of disabling normal carrier tune and using the pulse tuner in place that would be great. Alternatively if you held the tune button for a short couple of seconds it will choose pulser mode, if held longer it gives normal tune at whatever carrier power its set for. Another option would be to use the straight key jack when in the SSB mode to engage the tuning pulser. Who knows whats possible, only Elececraft!
