[Elecraft] Amplifier tuning K3 (was QRQ QSK)
A two-tone generator is OK for testing an amp on a spectrum analyzer for odd-order IM performance, but is one of the last things people should use for daily tuning of an amplifier. The most desirable thing is something that has a very low average power and full or even slightly above full peak power pulse. Single tone is fine, so long as the peaks are at or slightly over the maximum power ever expected, very narrow in width, and fairly wide gaps with no power. We really want low duty cycle pulses to tune with. 73 Tom - Original Message - From: "Greg" To: Sent: Friday, May 14, 2010 10:38 PM Subject: Re: [Elecraft] How is K3 QRQ QSK performance 50-100 WPM? > The K3 has a two tone oscillator built in that you can use > for tuning... 73 > de Greg-N4CC > > __ > 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 __ 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
During a recent contest, one speedy cw op was cruising something over 30 wpm but was hard to copy as there was no tone at all on his signal, nothing but key clicks were being transmitted. No, he was not near me. Unknown radio.

I know that W4BQF routinely copies and sends over 100WPM, and he uses an Icom 7700. Having owned the '7700, its QSK is very fast -- until you add an external amp where keying artifacts begin appearing on anything but the fastest switching amps. The '7800 I owned did not have this problem, nor does the K3.

Re: [Elecraft] K3: QRQ high-speed QSK
This is a *little* OT, but I've just read in a 1914 WT book that they were regularly running at 300wpm on spark transmitters. The very clever trick was to operate the spark continuously and FSK it by switching between taps in the antenna tank. The receivers were direct conversion using rotary generators on nominal freq then recording the difference on a pen recorder - I suppose an undulator by another name. I don't think FSK and DC were phrases in common use at the time. Astonishing. David G3UNA > > There are some really good QRQ ops out there.

Re: [Elecraft] K3: QRQ high-speed QSK
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.

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. He would send a macro at a high speed, and I would try to break him using two letters (ie). Almost always he could hear my first break attempt. We went up to 75 wpm and he could still hear my bk. So, we are wondering about what is going on concerning this thread. Now, it is possible my friend is hearing between words, but the bk could be heard almost 100%.

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.

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.

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

For my two HC4-equipped headsets I use very close to the same K3 settings that John, W1QS posted and I get similar results. But I don't understand "TX Equalizer= flat with 6 dB boast". John, do you mean you boost all ranges by 6 dB? Or???

[Elecraft] OT: virtual serial port setup help needed
I have 8 'real' (not usb) serial ports on my computer. My K3 is using Com 3. Using Ham Radio Deluxe or DXLabs, I can interface with my K3, no problem. I want to connect to my K3 using either HRD or DXLabs, then using my softrock sdr and PowerSDR-IF, I can display the IF of the K3 as a panadapter. All this works just fine, no problems. Now comes my problem.. If I wish to use any other program, such as K3 utility, or EZ-K3, at the same time... I of course get the 'device is already in use' warning. I know I 'should' be able to set up either LP-Bridge, or VSPE, and be able to use both at the same, but I am unable to figure out how to set up either virtual port pgm to do it. To many possible setup options, and to little understanding on the part of this operator, sigh. Everything I read shrugs it off as, just create another port, then connect to the port you created I have tried every way I can figure out to do this, with no joy! I have read and reread all the various instructions I could found, and I'm just not able to accomplish this on my own. I need some hands on help. Would someone please email me off the list and set up a sked with me on echolink, to walk me through how to set up either (or both) pgms so i can do this?

[Elecraft] First impressions of my Elecraft K3.
Hello all, since some time ago I have my K3 assembled, almost a month, and just yesterday I put it on work during a Portuguese Monument activation under call CQ0ODX/P. K3 works everyday, however due to severe antenna restrictions I am not able to test it in a normal antenna situation. Yesterday I did my operation inside my car and there are a lot to improve inside it to give me a confortable operation. Maybe using a portable table will be better, however during rainy time, like yesterday, it would not the perfect tool to use :) :) . Despite big lacks of my side, it was my first operation inside my new car, I was able to do 150 qso's on 30 meters using a 30m dipole. First configuration was using dipole inverted shape, swr was 1:1, so no need to use ATU and longest qso was to ZL2IFB, by the way, we started operation around 8:00 o'clock, maybe a bit later. K3 worked very nicely, was very easy to operate with and signals were very easy to listen up. Time to time I needed to use RIT but that was easy and pleasante too. At same time I used my winkey and again K3 had no problems. K3 is very suitable for activations like I did yesterday, its ergnomics are very friendly and operation is very easy and smoth. Sadly I did not pictures (I was all the time doing qso's or calling, so no time for pictures) however CT1CQK and CT1FMX did pictures and films, later I will give you link for both. Best 73 and till next email.

Re: [Elecraft] K3 - SPE Expert 1K-FA and ALC
Sorry, with all due respect this is HORRIBLE advice. I won't argue with those that say that the ALC should be connected for its protective value. But it should not be depended on to control output level -- the exciter should be adjusted to produce approximately the drive required for full output. The SPE Expert may have an exclusive design, but it is not exclusive enough to include a time machine so that it can know how loud the operator is planning to talk, and it doesn't control the delay inherent in the exciter's ALC circuitry. The result is guaranteed to be increased distortion.

Re: [Elecraft] OT: virtual serial port setup help needed
Hi, I use LP-Bridge and don't remember (it's been a while) that it was terrible hard to set up. Look at screen shot here: http://ab2tc.getmyip.com:8000/pictures/lp_bridge.png In the upper left corner you see that the K3 is connected to COM4 at 38400 baud. COM4 is the real physical port on the PC that the K3 is connected to. In my case COM4 is a USB dongle, but that is irrelevant. Ignore the PowerSDR if you don't use that. Along the bottom you see a row of virtual ports COM10-COM14, only two of which are actually in use. COM10 is the port I have HRD pointed at. HRD is also set to 38400 baud but since the port is virtual I suspect the speed does not matter. COM11 is for a little cute S-meter program that I seldom use. Try it out. It's not that hard.

Re: [Elecraft] K3 - SPE Expert 1K-FA and ALC
Because if you are using something you can measure, like two tone, the gains are already set and steady. To measure leading edge distortions before an AGC loop or loops bite and settle takes some pretty expensive lab equipment, both before and after the transmitter/amp. What you got? It IS terrible advice. 73, Guy. On Sat, May 15, 2010 at 4:25 PM, David M.

Re: [Elecraft] K3 - SPE Expert 1K-FA and ALC
In general, I would agree with You and Guy and Vic. However, Gianfranco of SPE (Expert) suggests running the exciter at full power. He says there is no splatter and the proof of the pudding is in the eating. That seems to be true. I can't see any splatter on the WaveNode and several on the air tests report fine audio with no splatter. I repeat: There is something here we don't understand.

Re: [Elecraft] K3 - SPE Expert 1K-FA and ALC
Hi Vic Yup, ALC is not feedforward correction system. It is a servo like mechanism that corrects after the distortion has left, then it corrects. For SSB splatter this is a disaster which we dont need. The worst example of this is the Yaesu Quadra, it is the worst buckshot generator on the bands. The Quadra when used with ALC is an horrendous splatter generator. Closing the stable door after the horse has bolted, is not good amateur practice. Having the horse bolt several hundred times during a QSO is not pleasant for others. Feedback ALC systems dont belong in modern ham equipment. All Japanese transceivers have ALC overshoot issues. We need to get back to the transmitter gain or drive adjustments that set the drive power precisely with no overshoot. Its a nice dream that does not exist in modern ham transceiver. Most commercial and mil SSB equipment have a drive or TGA(transmitter gain adjustment) knob.

Re: [Elecraft] Son of K3??
I talked to a Kenwood rep at Dayton this morning. He said the TS-590 would have the best receiver specs out there. I asked if it would beat the K3 and he said the TS-590 would have the best receiver specs out there. The radio has an IF of 11MHz and two stock roofing filters - 2.8KHz and 500Hz - no spare slots and no options. It will not have a second receiver or option for one. I remarked on it's superficial similarity to the K3 and he said that the K3 had done some things right and that they were not too proud to use them. Price is expected to be $1800 and expected to be available in the fall. The model on display was an operational hand-built prototype with some features disabled. As a very happy K3 owner, if Kenwood can meet or slightly exceed the K3 receiver numbers with this radio then more power to them. It still won't match the overall capability of the K3 and Kenwood certainly won't match the Elecraft level of support. It might, however, attract users who are looking for a radio with good specs at a mid-level price and without the complications (or availability) of options.

[Elecraft] Son of K3??
I won't buy one, even if it were a better radio. Kenwood service has a very very bad reputation. I did notice though, that they included BAND KEYS aka tunable memories. For those that would use K3/590 outside of the confines PC based software, a must I think. Disappointed there is no Analog S-meter, that one might have me considering risking Kenwood Service... Nehhh, they are the pits. If I might suggest if there was a "rig killer" out there it would be named Kenwood Service. ;-) PS - Or Kenwood parts - ack! [Elecraft] Son of K3?? William Ravenel wmrav at triad.rr.com Sat May 15 20:24:20 EDT 2010 Previous message: [Elecraft] KPA100 & KAT100 For sale or trade! Fully assembled Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I talked to a Kenwood rep at Dayton this morning. He said the TS-590 would have the best receiver specs out there. I asked if it would beat the K3 and he said the TS-590 would have the best receiver specs out there. The radio has an IF of 11MHz and two stock roofing filters - 2.8KHz and 500Hz - no spare slots and no options. It will not have a second receiver or option for one. I remarked on it's superficial similarity to the K3 and he said that the K3 had done some things right and that they were not too proud to use them. Price is expected to be $1800 and expected to be available in the fall. The model on display was an operational hand-built prototype with some features disabled. As a very happy K3 owner, if Kenwood can meet or slightly exceed the K3 receiver numbers with this radio then more power to them. It still won't match the overall capability of the K3 and Kenwood certainly won't match the Elecraft level of support. It might, however, attract users who are looking for a radio with good specs at a mid-level price and without the complications (or availability) of options.

I can't see any splatter on the WaveNode and >>several on the air tests report fine audio with no >>splatter. >>I repeat: There is something here we don't understand. We went through this ALC stuff just one month or so ago. The problem with ALC is the ALC system response delay and the propagation delay through the radio, especially narrow filters. The leading edge of everything takes a hit until the ALC level comes up. The time delay to interact with the system is the problem. With a reasonable ALC hang time the splatter is not too objectionable on a crowded band, but on real quiet bands it can be disruptive to weak signals. It is a very broad bandwidth short duration problem. In my opinion it isn't the major problem we face with SSB bandwidth and we may be over focusing a little on it. The duration is so short the average power is very low, but it is there. It would be very easy to miss on a spectrum analyzer, as a matter of fact I would say it is nearly impossible to catch. A selective level meter would be a far better detector. The real problem is the K3 has a unique ALC system that is in front of the filtering, so leading edge delay isn't an issue. Since the K3 has no leading edge transients, and since anything after the radio (except a clamp or fast attenuator) can not fix the transients, I don't see why anyone would want to run external ALC with the K3. Here is what Wayne said: <<< K3 external ALC setup is covered on page 27 of the owner's manual. Please read this page before attempting to use external ALC with any amplifier. Executive summary: 1. DO NOT turn the K3's power all the way up and use amplifier ALC to maintain peak power at the output of your amplifier. This WILL NOT work. 2. Instead, adjust the power level at the K3 to provide just enough drive to hit the peak power desired at the amp. You may want to set CONFIG:PWR SET to PER BAND so you don't have to adjust power each time you change bands. (This is also covered on page 27.) 3. External ALC is accommodated as a safety backup in the event that peak power suddenly increases, etc., due to a failure or load change. When properly applied, it will rarely be needed. Technical details: The K3 is designed to *not* depend on fast external ALC, because that absolutely, positively causes splatter. We studied lab work from several authors on this topic and decided to take a different approach: our fast ALC is all applied *ahead* of the 1st I.F. crystal filter (it's handled by DSP, at the AF and 2nd I.F. stages). We do apply slow, long-term ALC after the crystal filter, but this can't cause splatter because of the long time constant. External ALC, if used, is factored into this part of the equation. Yes, the K3 is unique in this regard. It may be slightly inconvenient, but it will result in a cleaner signal. 73, Wayne N6KR >> 73 Tom __ 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 - SPE Expert 1K-FA and ALC
Hi Dave, Thank you for the pictures. Worth thousand words, etc. And there IS difference between the two. Can you detail the setup from end to end, particularly your RX setup and K3 TX voice settings? I'm not sure what your audio waveform is from exactly in A and B, you'll need to tell us. But if that's human voice, it's a very base-dominated voice spectrum, unlikely to generate obvious splatter. The 0-400 or 0-500 band, whatever it is, is 18 db above the next strongest band in your "modulation quickview", and so the lowest band is completely controlling the power, not the attack of the silibants. This would not be the measured waveform for a contest optimized voice, with the treble accentuated for "punch", where splatter-producing TX/amp setups show their true colors. Set up for contest "punch". Do the comparison with the lower frequencies severely reduced in the K3 TX equalization, and the compression up around 20-30. Or get your wife to do the voice and have her holler at the mike like it was the kids (only a few assumptions there...). Turn OFF the averaging in the program and leave the peak hold on. The duration and hence the average power of silibants are quite less than the lower frequencies, and the distortion products off silibants even less. It is the distortion's instantaneous peak power that causes the most problem, not its peak power times duration (average power). The speech used for the test should be on a recording. Run the K3 barefoot off the recording, bypassing the amp, measure and make your pictures, and then include the amp and repeat from the recording without changing anything on the K3. This is probably a 25 watt A/B and a 100 watt A/B. The receiving device should be run with FIXED gain, NO RX AGC, any overdrive issues worked out in advance. Compare those spectrums. But even this is still approximate, because the RX device (unless it's a very good RX device like another K3 or K2) can create the highest distortion which covers up any true differences. The real test would be to run a very stable square rise and fall CW dit with a pulse width of about 2 or 3 milliseconds with a repetition rate of about one second, and repeating the test for longer pulse widths. This requires a signal generator followed by a high power lab linear amp instead of a K3 to drive the amp, but would isolate added spectrum that occurs on predictable frequencies at predictable times and can be precisely measured. The receiving device and presentation would have to be certified for the general circumstances. I don't own this stuff either, just get to drool on it during isolated opportunities. As to others listening for splatter, one WOULD think others could hear it. However, back in the day of controversy over what rigs had and didn't have key clicks, it was amazing how many people could NOT hear or otherwise detect the bad clicks on a MEASURED dirty rig, for whatever reason I really don't know. So I'm skeptical since I don't see much difference in hearing splatter and hearing key clicks. The problem I have, even if the SBE does manage to do amplification relatively cleanly, is if someone else reads this thread later on without any blowback on the claim, the readers extrapolate to other amps and there it goes... So the SBE method is not going without blowback. SBE may think they have created a marketing differentiation, but for the time being they've crossed themselves off my list on account of recommending smashmouth drive and ALC. What else that I don't know about, yet? 73, Guy. On Sat, May 15, 2010 at 6:32 PM, David M. Elliott wrote: > > > These two screen shots were taken using a WaveNode WN2.

Re: [Elecraft] Son of K3??
Kenwood once made great HF radios. I have an old TS-930s that is quite a performer for its age. I found in side by side comparisons I was able to copy more weak signals with the 930s than with my K2. If I could copy on both, I would prefer the K2 because with dsp I was able to filter out all the noise. My new K3 is clearly the superior radio in all respects. I have also used a TS-2000. I thought it was a very poor quality radio and I sold it shortly after I bought it. I am very happy with the K3 and have zero desire for a change. I like Kenwood radios for VHF/UHF repeater and mobile use. They understand and implement APRS better than others and they are my choice for mobile public service work. -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Edward Dickinson, III Sent: Saturday, May 15, 2010 6:12 PM To: Elecraft@mailman.qth.net Cc: wm...@triad.rr.com Subject: [Elecraft] Son of K3??

[Elecraft] Elecraft CW Net Announcement
Good Evening, The weather has been quite pleasant this week. In the last couple days I have experienced 70 degree temperatures for the first time since last year. Even though I still have daffodils blooming I think spring is finally here and summer may arrive in only a couple months. I burned brush for most of the day since I only have a few weeks left before the dry season burn ban begins. The detritus from the wind storm is almost all gone. Conditions on twenty and forty meters have been good throughout the week. One night I set up for the 'coon hunt and forgot to change back to 100 watts for the next day. Only when I tried to turn down the power for the Thursday hunt did I find I had worked a sked at QRP levels. Neither of us noticed! Conditions were indeed good on twenty ;) Please join us tomorrow afternoon and evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP help) Sunday 2200z (Sunday 3 PM PDT) 14050 kHz Monday z (Sunday 5 PM PDT) 7045 kHz Stay well, Kevin.

Re: [Elecraft] Son of K3??
Hi If the new Kenwood does deliver K3 like performance at the reported price of 1800 dollars, its going to be a huge seller. This price is not much more than a TS480. What this competitive price means is that radios like the Yaesu FT5000 will struggle to find wide acceptance since its almost 3 times the price of this new Kenwood. This competitive pricing versus performance from Kenwood truly might be a new turning point in the ham radio market. What it also means is that big, expensive white elephant radios like the FTDX9000 and IC7800 might well be a thing of the past. Assuming that the Kenwood does deliver on its receiver performance claims, 2 of these radios at 3600 dollars will be a bargain. Elecraft could take the lead and produce a single receiver version of the K3 with a 200 watt PA, inbuilt power supply, and possibly a bigger front panel. However I dont see this happening. The high performance end of the ham radio market is certainly going to be crowded, the winners will certainly be the ham fraternity. The only losers are people like Icom who have expensive radios like the IC7700 and IC7800 which have marginal IMD dynamic range. From this perspective the Kenwood radio is a welcome!

Re: [Elecraft] K3 - SPE Expert 1K-FA and ALC
Thanks Guy for the well thought out response. Now we are getting somewhere. The setup is a K3 using an Elecraft hand microphone feeding an Expert 1K FA solid state linear to a Windom antenna. The detector is a WaveNode WM2. The RF sensor module is between the Expert and the Antenna. The WaveNode is described on their web site (You can Google it,) and the manual is there too. The K3 is set up using ESSB with a width of 3.2. The tx equalizer is flat except for bands 7 and 8 which are set for -6db. The audio was my spoken voice so would be different from A to B. I have been told that I have a "radio voice" and should have been in broadcasting. I made a few radio and tv commercials for a company I worked for in the mid 1970s and to this day I have people come up to me and ask if I was on the radio in Cleveland. Somehow they remember the voice after decades. As you say, it is very base dominated. The WaveNode is a really fun toy which I am just now figuring out how to use. What I look for to see splatter is the presence of colors other than green in the Modulation Quickview window. If I see that, I know there is splatter. If I don't, then I assume I am OK. As you suggest, I will try this with the tx equalizer set up for narrow contest operation. I'll let you know what happens. In any case, I am convinced that the K3 should be operated with the Expert with each band of the K3 set for only the power necessary to drive the Expert to its rated power. In my case, this is 15 watts plus or minus a few. It is interesting to note that I can drive the Expert to nearly full power with my QRP K2. I'll report back on further tests. Thanks for all your good words. 73 de W6BK On May 15, 2010, at 6:06 PM, Guy Olinger K2AV wrote: > Hi Dave, > > Thank you for the pictures.

Re: [Elecraft] First impressions of my Elecraft K3.
David, Glad you are enjoying that K3 - sounds like it worked very well for you in that less-than-great operating environment!! I am about three weeks away from placing my order for a K3 and can hardly wait to get my hands on one. 73, Jim / W6JHB -- View this message in context: http://elecraft.365791.n2.nabble.com/First-impressions-of-my-Elecraft-K3-tp5059591p5060741.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
[Elecraft] K3 the mountain Kenwood must climb.
The 570 cometh. Someone stated they asked a Kenwood rep for the spec's. His answere was, it will have the best out there, if ever there was a canned answere. It may well be a great radio. But you do get want you pay for. Yaesu and Icom have great high end radios and the cost. The K3 is better, but it is not a radio that cost only $1,800. Even without a sub reciever. With all the AM and FM. And the general covarage, the K3 is over 3 grand. With all the roofing options, the P3 to boot it can surpass the Kenwood with ease. The real point is, hopefully it will be a good radio for the money, A K3, no way. Not at that price. N6XVT 73 PS Good luck Kenwood ! If they do top the K3, we will all wait for the K4. All I know is, I have found my company!

[Elecraft] K3 S/N 4251 under construction
Hello All, Looking forward to having it on the air and really enjoying this part too. This K3 will be my home rig for now and my cruising rig on RED, our sailboat, in a couple of years. 73s, Richard KL0DR __ 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
