[Elecraft] QSK Master T/R switch and K3S
I have pulled my old QSK Master off the shelf for use with a K3S, KAT500, and AL-811H. This is the solid-state version, not the vacuum relay version of the QSK Master. My question is this: should I strap the QSK M for 2ms hold time after ptt release, or 8ms--and should I change the delay setting from 8ms in the K3S menu? QSK 811as!! The mind reels. Thanks for the help. 73 Eric WD6DBM __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] QSK question on KX3
Since getting my hands on the used KX3 and ancilliaries that came with it, I've been spending my spare time going thru the manuals and finding the various menu items hands on the rig. I've updated the firmware in the KX3 and PX3 but haven't done anything yet with the amp. One thing I notice is when I set the delay to zero and key the rig with VOX ptt set so there is no RF everything seems smooth. When I actually run RF into a 50 ohm load I notice the RX doesn't recover very gracefully between DIT's (running 20wpm or more) and I hear a really distracting audio disturbance on the speaker. I thought it might be from pushing the little speaker too hard and had audio gain way up because no antenna was connected so I tried again with phones and audio gain down around 20 and it is still there. AGC is off. Preamp on/off doesn't really make any difference. Filter settings make no difference. If I set delay to 005 ms it is gone but then I can only hear between letters and words wh ich is not full QSK. I can live with this, but before I bought this rig people I talked to told me the Elecraft rigs have really great QSK and I was expecting to run with zero delay. Is what I am hearing a sign something isn't right with this rig or do others get a similar experience? Have I missed something in setting up for full breakin?

Re: [Elecraft] Elecraft QSK
No, the real question is why doesn't Elecraft make a KPA1500! I agree about the Alpha PIN diodes. I had an Alpha 86 for a few years, and never had any trouble with the PIN diodes -- and I made plenty of 'antenna mistakes'. I sold it because I was tired of waiting the 90 seconds for it to warm up, and I believed that Elecraft was about to release the KPA800 and 1500. I suspect some of the PIN diode failures were due to static discharges. I had ICE antenna protectors that provided a good DC path to ground and a good lightning ground system. Or else I was lucky. 73, Vic, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 1 Mar 2017 01:14, wb6r...@mac.com wrote: The Elecraft KPA500 silent QSK is achieved without expensive PIN diodes but rather with relatively inexpensive switching diodes.

Re: [Elecraft] QSK the K3
I have the old synthesizers (K3 S/N 1428 running version 5.29) and, although I don't often use QSK, I did check after seeing Bill's comments. I believe Bill is right and the QSK response does appear to be slower. I normally run cw between 24 and 32 wpm. I did set CW QRQ to on and it does seem to switch faster but it's hard to quantify. Are there any other parameters to change for those of us who may not upgrade synthesizers? Tnx 73, Gerry, W1GD Bill, There were some firmware changes made when the new synthesizers were introduced, and as I recall some of those changes involved QSK operation. Initial reports on the new synthesizers from users indicated that QSK was better. I have not seen any reports of QSK changes with the old synthesizers, but you may have hit on something - continue with the tests and tell us your results. 73, Don W3FPR On 7/16/2015 10:00 AM, Bill Stravinsky via Elecraft wrote: When I first got my K3 in 2009 I thought the QSK was fabulous and used it every so often.

Re: [Elecraft] QSK and the K3
Bill - I have used QSK for thousands of QSOs since I got my K3 4 years ago. I have seen no changes at all.. but I am not a real QRQ op. I usually run about 28 wpm... sometimes about 32, and very rarely a bit higher than that. I did put in the new Synth boards, and have verified that QSK is now silky smooth up to speeds much higher than I dare try to operate. Best of luck getting everything to play the way you want it to.

Re: [Elecraft] QSK and the K3
I’m wondering what tests Electaft is suggesting? Remember the QSK (right side of band-switch) has two settings Full and Simi. Also in the Config menu CW QRQ = ON, seems to help, gives you the + sign on the right bottom of the display.

Re: [Elecraft] QSK and the K3
If one is going to upgrade one's K3 to the new synthesizer, then table any QSK concerns until you have that in place. Just one of the benefits is that the new synthesizer does state changes way faster than the old syn. RX/TX state changes are what QSK is all about. Besides the new syn, there have been a lot of changes to QSK, some number of varieties of QSK now, since the olden days of firmware version 3.xx. Way lotsa stuff under the bridge since then. Includes some very significant improvements to AGC and K3 performance listening to a pile-up.

[Elecraft] QSK clicking on Tx...
Apologies if this has been covered before. I have looked but found no definitive answer. This morning, after getting up early to catch the greyline for HK0NA on 80M, (which was successful, 80M CW 40M SSB bagged with my 100W and bit of wire.) I noticed a clicking from the rear left (I think) of my K3 whenever I TX'd. QSK semi instead of fully reduced it and it was not evident on on Test mode. I am assuming this is connected with the PIN diodes. It was only evident on 80M. SWR was 1:1 I removed all leads suspecting RFI but no change. The clicking gradually reduced over time... wierd I did not notice this 2 weeks ago when I last used 80M CW. Any suggestions ? I only ask because I leave for Bhutan in 4 days and I'm taking it with me for a few days operating and hope its not a pre-courser of something horrible.

Re: [Elecraft] QSK clicking on Tx...
It sounds as if you were using the antenna coupler. Perhaps it was one of the relays there that was clicking. It may be that the edge of a band in the auto tuner was bridged by the transmit and receive frequencies in split mode and the antenna coupler was changing settings with the keying. I don't know for sure so some comment from one of the gurus at Elecraft would be useful.

Re: [Elecraft] QSK OFF
Let's answer Paul's actual question, Can I turn QSK off? I think you mean require some form of manual PTT before you can send and the answer is Yes. Turn off VOX by holding BAND DOWN. Without manual PTT, when you send, it won't make RF and it will tell you in VFO B. You can assert PTT through the rear panel jack, or with the XMIT function on the front panel and then transmit. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org On 11/29/2011 9:26 AM, Guy Olinger K2AV wrote: It's on the front panel.

QSK provides the ability to hear between CW characters (or elements if it's fast enough) while sending. Semi QSK is the ability to go from xmit to rx without touching any controls (i.e. VOX for CW).

Re: [Elecraft] QSK THUMPS?
One of the issues found in QSK operation is that TX-RX state changes MUST modulated the received envelope. It is a fact that the RX stream must be turned off, and then turned on, to support transmitting and that is a modulation. The RX is ON after the latter state change and will hear the modulation. The only way to modify that modulation is by changing the shape and rise/fall times. This is the point at which the desire to hear between bauds, and to not hear artifacts of the state changes, are at odds with one another. A slower transition does less modulation, but slower can cause the transition to exceed the baud space, defeating the reason for QSK in the first place. To have clean hearing between bauds at 25 WPM does not allow time for soft and no-thump transitions. If there is anything being received, then the modulation of the RF envelope creates sidebands. The wider the energy being modulated, the greater likelihood of modulation sidebands. Set TX TEST, CW mode, QSK, then turn MON all the way down. Now hold down dits with your paddle and tune across a loud signal of any kind. Loud carrier between 7.2 and 7.3 is a good test. Most of my friends call that thumps, particularly if there is a really loud signal in the passband. This change is being imposed as far forward as the PRE/ATT. If you study the schematics, a lot of RF and 1st IF circuitry is either being switched out or reversed, thus imposing the modulation at points of mandatory artifact sideband generation. Having said that Now turn the RX EQ to -16 in bands 1 and 2 and note the large drop in the amplitude of the thump. Also note (if you have the roofing filters for this) that the thumping is quite more pronounced with wide roofing filters than narrow. This is one instance where having headsets with hi fi response down to 15 Hz is no advantage. 73, Guy.

The default (and fastest) QSK transmit delay setting (TX DLY) is 8 ms. At 20 WPM, this shortens the length of a nominal 60 ms dit element to 52 ms long. To regain this lost dit time when using QSK, the default setting for the CW WGHT element-to-space ratio is 1.15. (52 ms X 1.15 = 60 ms approximately.) So the 1.15 default weight factor was seemingly arrived at by using 20 WPM as a nominal QSK code speed. Assuming this reasoning is correct (Wayne/Eric, please enlighten me if it isn't), two things come to mind: First, since amplifier T-R speeds below 4 ms are readily achievable using vacuum RF relays, and faster than that using PIN diodes, it might make sense to make TX DLY settings of less than 8 ms available -- say, down to 2 ms, while still leaving the default at 8 ms. Second, as QSK code speed is increased, the TX DLY factor (whatever it is, currently 8 ms by default) becomes a larger and larger proportion of the element time, requiring a larger weight ratio to correct for the TX DLY shortening. For example, at 25 WPM (48 ms element) and TX DLY = 8 ms, a CW WGHT setting of 1.20 would be correct; at 30 WPM (40 ms element), again with TX DLY = 8 ms, a CW WGHT setting of 1.25 would be correct; and so on. Might it make sense to optionally have CW WGHT track with the user's code speed setting during QSK operation? (You wouldn't want to do this in non-QSK CW mode, of course.) The tracking formula would be based on the user's TX DLY setting, whether 8 ms or something faster/slower. Of course, this would only apply if the internal CW keyer were being used; if using an external key or keyer, you'd be stuck with a fixed CW WGHT setting... Comments?

[Elecraft] QSK CW: TX DLY vs CW WGHT with internal keyer
Just thinking out loud here, having recently upgraded my 3-500Z amplifier with fast vacuum T-R relays... The default (and fastest) QSK transmit delay setting (TX DLY) is 8 ms. At 20 WPM, this shortens the length of a nominal 60 ms dit element to 52 ms long. To regain this lost dit time when using QSK, the default setting for the CW WGHT element-to-space ratio is 1.15. (52 ms X 1.15 = 60 ms approximately.) So the 1.15 default weight factor was seemingly arrived at by using 20 WPM as a nominal QSK code speed. Assuming this reasoning is correct (Wayne/Eric, please enlighten me if it isn't), two things come to mind: First, since amplifier T-R speeds below 4 ms are readily achievable using vacuum RF relays, and faster than that using PIN diodes, it might make sense to make TX DLY settings of less than 8 ms available -- say, down to 2 ms, while still leaving the default at 8 ms.

[Elecraft] QSK Mod For Ameritron ALS-600 or ALS-500
Hi All, I recently added an Ameritron ALS-600 amp to my shack. Initially I wasn't that keen on the ALS-600 because it wasn't QSK. However, I read about a mod that Phil Salas, AD5X, came up with, and it is cheap and easy. You can find all the details on Phil's website, www.ad5x.com. Anyway, I bought the amp, and today I added the mod. It went very quickly--no fuss. Works very well, and costs only a small fraction of what a QSK accessory would normally run. Phil has a complete kit, with PC board, for $31 shipped, or you can root around and find the parts yourself, and make your own board. I strongly recommend Phil's kit. The factory relay is removed, and two small molded relays are substituted in the mod. You also add a diode on the PC board, and connect a few new wires. That's it! The old relay is very noisey, but the replacements are much, much quieter. You still hear some chatter, but the improvement is very significant. Everything works very well with my K3, so I'm pretty happy at this point. I don't use the amp all the time, but I really needed the help, particularly on 40 meters, when condx aren't all that great. Anyway, I thought some other K2/K3 owners might be interested in the process.

[Elecraft] QSK
...input from the Elecraft community about a new amplifier... ...Acom 1010 but I can not determine... that amplifier really has QSK. ...I love QSK... Jim: My $.02 worth - I have an Acom 1000 - absolutely full true QSK. It takes advantage of the Ft-1000mp QSK feature - the 'ready to xmit' signal is fed from the radio to the amp. The amp closes it's relays and returns an 'OK' signal to the radio. The radio then produces the neccessary RF. At the conclusion of the character, the proceedure is reversed. The amp is NEVER hot-switched. All this from the closure of the key in less than the blink of an eye, and in complete silence - a marvel to behold. It produces +/- 1000 watts out, 160 to 6m. The Acom 1010 is a lower powered version - lighter for DXpeditions, 600w out but no 6m coverage. Same GU74b tetrode. Not to say that there aren't other good amps out there.

Re: [Elecraft] QSK options inquiry
I recall sometime ago enquiring of Ron Stone GW3YDX at Vine (UK Acom sales) and being told that the 1010 doesn't have vacuum relays and to go with the 1000 if I was serious about QSK.

Re: [Elecraft] QSK options inquiry
Doug, Here's what I've gleaned on the 1010 The 1010 is a different beastie from the 1000. It isn't just a 1000 without 6M. 1) takes more drive for full output. 2) full output at least a few hundred watts less. (I also believe the transformer is not has hefty) 3) an electronicly controlled bias circuit 4) The RF deck is different, it doesn't have the extra shielding the 1000 has. This is both a plus (if you change tubes) and a potential negative. It is a good amp for countries with an enforced 400 W power limit. Unfortunately I can't comment on the amp key circuit or QSK. 73 de Brian/K3KO Jim Danehy wrote: Doug Same problem here finding out anything about sales in North America.

Re: [Elecraft] qsk options inquiry
I have the Acom 1000 and use it with the K3/100 (#250)...full QSK, no problems at all with keying,(up to 44wpm) etc. I got it in 2004. I have made over 15000 Qs with many of these Qs during contest operations, phone, cw and rtty. I do crank it back to 500w out when running rtty so as to run a little cooler. If you like computer controlled amps, this is a remarkable little amp, very quiet and puts out about 600w or so. It is NOT a 1000w amp...the specs on the tube the 4CX800 say plate dissipation is 800w...plug in typical efficiency and that will put it down around 600wto 680wMy LP-100 shows 800w peak and my Bird shows around 600-650w (key dwn) output into Steppir 3 ele yagi. Not sure that anyone could tell the difference over the air if power was 1000w or 600w. Not sure about the marketing of the amp now...did Array Solutions or DX Eng pick up the line in the US? A recent email to K6ND (US rep) garnered a response from a technician in LZ land. All in all, I like the amp and would recommend one to someone in the US or EU. 73 Tom CX7TT __ 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

I have had this amp since late 2001 so it's an early model. The ACOM 1k runs hot but well within it's rated temp ratings @1Kw high duty cycle. Keep the dust filter at the back well cleaned and ensure that the exhaust vent is free. I measured a little over 1100 watts into a Dummy load on most bands. My measurement is based on a Dummy load and an LP-100 calibrated against a Rohde Schwarz power sensor borrowed from work the power meter on the acom 1k can be a little optimistic, reading around 1300W for 1050W into the dummy load ;-) if you are only getting ~ 600W out of your Acom 1k you may want to check that the transformer taps are set correctly for your line voltage and that your shack supply is not 'sagging' too much on keydown 73 Brendan EI6IZ -- 73 Brendan EI6IZ __ 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

The QSK box from Array Solutions (they call it QSK Master) would be a way to integrate my Elecraft rigs with my Henry amplifier as well as the smaller Hercules II. I have thought about the Acom 1010 but I can not determine from the Internet whether that amplifier really has QSK. I have also considered the smaller 600 to 700 watt Tokyo Hy-power amps. I have not followed the saga of the Elecraft amps so maybe somebody can apprise me of where that has gone. Your advice and suggestions would be greatly appreciated. I love QSK. I realize some do not. 73, Jim W9VNE Cincinnati, Ohio __ 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 __ 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

I worked with Doc Sheller on the DEO QSK1500 many years ago ... With the current behavior of the K3's Key Out jack, you should be able to use the FT-757 instructions in the DEO QSK1500 manual (K3, Key Out to QSK 1500 Amp Rly In, and QSK1500 AMP RLY Out to the SB-200 PTT line). The QSK 1500 will follow keying from the K3 ... If you want to add an extra level of safety, connect a pull-up resistor between +5V and the K3 INH input and connect the QSK 1500 Pos Key Out to the INH input of the K3 (close to ground to allow RF). 73, ...

Now I have the K3 key out going to 425 PTT in and the amp if following the keying. In the Ten Tec method, you connect the key to to amp and have it send a keyed signal to the key input on the K3.

[Elecraft] QSK - Why don't you like it?
I've always wondered why some don't like QSK. Today, I may have had an epiphany. I wonder if the dislike is really just a mix issue? Maybe those who dislike QSK just have their sidetone too low and it gets lost in the band noise? In both my TenTec rigs and my Elecraft rigs, side tone is controlled by a separate control, apart from the AF gain. I set the sidetone, then adjust the AF gain to mix in as much or little of the band as I want. I can have it be 80% sidetone with a hint of the band turn the AF gain up to match or exceed the volume of the sidetone. Sometimes, I turn the AF gain down to make the band just a bit of background noise. - Keith N1AS - - SKCC 344c - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] QSK and Monitor on the K3
I ran QSK all weekend in the CQP with the K3 driving an Alpha 87A and a Pro3 driving another 87A. I like to reduce the monitor level as low as possible and on the K3/87A combo, it was extremely quiet and smooth. But the Pro3 could not subdued by comparison. First of all, even with the sidetone reduced to zero, there was still leakage that was much louder than what the K3 could be adjusted to. In addition, the Pro3 had popping and slapping on the TX/RX transitions between code elements that was very tiring. The Pro3 in one ear made it impossible to copy weak signals on the K3 in the other ear. I was constantly having to manually switch the headphones to the K3 only when working a station on that radio. The other way was fine ... K3 transmitting in one ear while copying a weak signal on the Pro3 in the other ear. At least six K3's were on in the CQP: AB7R, N0SS, W6GV (K2VCO), N6XI, K7RAT (N6TR) and K6YT (W0YK). 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] QSK and the 2nd receiver

Re: [Elecraft] QSK and the 2nd receiver
No Stewart, that is SO2R. I use SO2V a lot here with the FT1kMP and that is what you will get with the K3, but a lot better. With the MP you can only listen on the same band because of the way the sub rx path is routed, although it is possible on the higher bands The K3 has an independant sub rx so I assuming you can listen on different bands. Obviously when the radio goes into transmit the rx antennas are disconnected. For SO2R here I have a WX0B Sixpak antenna switch at the base of the tower, a pair of Topten band decoders and two Dunestar 600 bandpass filters in the shack, together with two separate 90m runs of H100 coax and two 6 way screened cable runs. That's SO2R. It's ggod fun Do a Google search on WX0B, Topten and SO2R for more info. I can't actually do SO2R at present as I sold my K2, so egerly awaiting my K3 which I am sure will be Radio 1 in the system. BTW, in the recent IARU SSB FD, we were using SR2O, otherwise known as Big Knob Man and Little Knob Man. We used my GU8D-special (designed for IOTA contest) SR2O unit for switching the mic, ie first one to hit the footswitch grabs the tx. Good fun.

At these speeds and during a contest, I NEED to hear everything immediately (that is what top-end contesting is about). So not hearing between dits at slow contest speeds of 32 wpm is an issue for me. NOTE that I still used the K2 despite that deficit because OVERALL, it is a great radio. But for someone used to real QSK, this is not real QSK. Ask other serious contesters and they will say the same. For most K2 users, who are clearly not serious contesters, this is not an issue at all. Since the K3 says very much better QSK than the K2, I would easily assume that the deficit is real and acknowledged. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] QSK revisited
After my last email on comparing QSK implementations in the K2 and the Yaesu FT-1000MP and the comments from knowledgeable people on this forum, I decided to measure carefully and to make more careful notes on what I heard. I setup a K2 and an MP to transmit at the same frequency into dummy loads. To test the K2, I transmitted continuously on the MP at a level where the K2 showed a steady S9 signal. While this was being received by the K2, I set up my keyer to transmit the letter v at different speeds on the K2. I listened to the K2 and analyzed the sound using Spectrogram. I then did the whole thing with the MP as the device under test. The details of the test, the results, and images of the Spectrogram screenshots can be found at http://rajiv.dewan.info/qsk/ My subjective opinion is that the K2 is great if all one is interested in is inter-character or inter-word reception. In fact, the hang time is so well calibrated that it is very silent and easy on the ears. This is especially important for long contests. Inter-element reception is very demanding. For this purpose, I prefer the Elecraft K2 while transmitting up to 20wpm. At 25wpm or greater, the K2 essentially does not receive between elements. At 30 wpm Yaesu still has a usable QSK implementation but the extra noise is tiring. I do not think I could stand the noise from 30wpm or faster for long during a long contest. Hang time can be increased (Menu item 7-4 increased from 5 to 7 or 10ms) to where the QSK would be essentially be useless between elements but would serve some purpose to detect signals between words. With the increased hang time, where inter-element QSK is essentially disabled, I prefer the K2 as the Yaesu remains noisier. I will have to try even larger hang times and compare the sound.

RE: [Elecraft] QSK revisited
Hi Raj, Tnx for the info from your tests. I find I really like QSK when I'm trying to work DX, like with the current 4O3T operation. But when I am running stations in a contest I do not use QSK. Too rough on the ears using QSK all the time. But with good QSK you can pick out your call right away when 4O3T came back without guessing or asking for repeats. Even at the speeds 4O3T was using on the high bands it sounded good and you can hear between the elements without pops with the TS950SDX and Acom 2000A. I made the R17 mod plus I set T-R to I believe .01 or .02 which got rid of the pops. It sounds quiet. Just can't hear between the elements. But that is okay since I use the K2 for Dxpeditions.

RE: [Elecraft] QSK
Raj, You were able to copy between the elements with the K2 at 35WPM? If so, I wonder what is different about your K2? Serial number? I have felt that the QSK was the one weak point of the K2. I can't hear between elements above about 16wpm. Yet when I played with Yaesu's 1K series I was able to hear between elements.

My suspicion is that he didn't really mean 'elements', but rather letters. No K2 of any serial number can hear between elements (dits/dahs) at 35 wpm. The K2's QSK is much smoother and quieter than most other radios. It is, however, not particularly fast. I've made a mod to speed it up (see http://www.qslnet.de/member/la3za/K2/modAny.html, look for Faster QSK Performance ) but the best it can do is around 22 wpm.

Good question. While the signaling rate of a CW signal does have an affect on bandwidth, the majority of the wideband products come from the rapid rise and fall times of the signal envelope. (that's why key clicks are heard so far away from the operating frequency) Don't expect a 99 wpm signal to be much wider than 35 wpm. That said, no one can copy a 99 wpm CW signal. The top QRQ guys are around 60 wpm. With the regulation by bandwidth, does this now put a speed limit on cw? Potentially, but that limit is so high as to be practically no limit.

Most QRQ ops copy in their heads. They wouldn't lower themselves to use a reader. Back in the late 70's, when I was a Novice, and later a General, I was involved in the WV Novice Net. A couple of the net control guys were blind hams. They would call the net at 5 wpm, go through the traffic, close it, and then call each other on the 'net frequency -- at 40+ wpm! They both had CW keyboards (which were pretty new back then), and would converse quite a bit back and forth at these speeds. A few hams out there can skip along at 30-40 WPM but they are in the minority by far. Contesters don't count as they are locked into a set format and not much information is actually exchanged except for the required data. Most of the really, really good contesters I know can also copy conversationally QRQ CW. Me? I can do almost 30 wpm in a contest, but I'm back down below 24 for conversational CW. Really good high speed telegraphers are rather scarce. (I'm speaking of those using straight keys or bugs, or sideswiper keys). That's pretty much a dead art.

[Elecraft] QSK Redux
I asked a question about the audio pop that occurs in cw when T-R is set to 0 (QSK), I discovered a 1993 thread that discussed lowering a resistance value. Two questions for those who have done it. First how effective was it? Meaning at what speed could you still hear between character elements ( dots and dashes - the subatomic particles of cw). And did it have a deleterious effect on your transmit key form? Also after you did the mod did it eliminate the pop, or just reduce it. The reason I ask is today I was chasing an A71 and the EU wall was up in full force. At a T-R setting of .01 I couldn't tell when he started to transmit. I'd say I was running about 30wpm. I ended up transfering the flag to the 756Pro where I was able to achieve full break in. And no, with the EU wall up I knew I had a snowballs chance of working him. Fun trying just the same.

Re: [Elecraft] QSK Redux
Ouch, 25 wpm is cw with training wheels. In the real world people don't send that slow. Bummer. I'll check out the site you referenced. I don't have a KDSP2, being a code kind of guy I am good to go with the KAF2. I love the receive qualities of my K2, and really, really wanted to make it my main HF rig. But if it isn't capable of QSK it can't take over Op Pos #1 for serious DXing. But I love the radio and it will get lots of non-DX use. QSK is the holy grail of cw ops. I am kicking myself as the best QSK I ever owned was a freak of nature. In the 1980's I had a Yaesu FT-757 GX II that held QSK beyond 40 wpm. Just the fluke of the components.
