[Elecraft] RE SDR - May break in the future (was K3 vs. 7600)
-Original Message- From: Steve, NN4X That is something which I keep very much in mind with radios like the Flex, and the idea of PC-dominated radios in general - really, you're always potentially one Windows update away from breaking the rig. If the company goes out of business, or does not feel like supporting an X-year old, non-current version of their product, you are done. Over and out. -- I'd not thought about that but I think Steve is right on. A hardware or self contained rig will continue to work even if the company goes out of business or the rest of the world around the rig changes. Once it works, it always works. If the company goes away, the rig still works. The true SW radios (Flex, others?) depend on having the right version of Windows. When Windows changes and the flex SW doesn't work, your radio doesn't work. So to keep your old Flex running, you have to keep your old PC running as well. No upgrades. And good luck if your 8 or 10 yr old PC needs to have a part replaced. Now, think about the value of a 20 year old Flex radio. Compare that to the value of a 20 Yr old Drake or Heathkit rig. One is a rig you can put on the air, the other is probably a doorstop. - Keith N1AS - - K3 711 - __ 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

So, how easy is it to build the K2? So easy, you can do it when you're too sick to go to work :-) I'm not a kit builder. I built my K2 because I couldn't afford to pay to have it done. I bought the pre-wound toroids and recommend them highly. I also bought the unPCB kit which actually made the build time longer due to initial prep work, but created a K2 that was more to my liking. Anyway, about the time the K2 arrived I got sick. I was tired, and my head was full of snot. One of those nasty colds where all you can do is watch soap operas. Guess what, I found that the K2 took about the same effort as watching TV. Read 1 paragraph. Blow nose. Find a part. Locate the target location on the board. Blow nose. Mount part, double check orientation, solder part. Blow nose. Check off step in the manual. I move slowly and deliberately. It took me about 40 hours of build time with my basic K2.

Re: [Elecraft] Amp choices for QRP K3?
Why go with an external amp? Well, I had a K2/10. Upgraded to K2/100 then went to K3. I could not use the K2 100 watt PA on the K3. Had I bought a generic external linear for the K2, I'd still be using it with the K3. The other driver would be cost. If the external amp solution is cheaper than the 100 watt internal PA, it would be worth considering. But, your point is well taken.

Re: [Elecraft] K3 Complexity

It's like a modern HW-101 for me, just as simple as can be. Now, as to promised features vs. fixes, this is a tough call. If the features had not been promised then it would be clear to me - give me a rig with limited features that is flawless rather than a Microsoft rig (lots of features, many bugs). I too want sync AM detection but if getting it means my AGC behaves badly in a pile-up, I'll take the AGC fix and wait on sync. But, wait, it was promised that we'd have sync detection.

Re: [Elecraft] K3 audio
I've stayed out of this thread and have only skimmed it but I'll weigh in a bit now. I have very good hearing. I listen to my K3 using high fidelity headphones only - I never use the speaker. I operate CW only. My rig sounds very good. I do have the Radio Shack level control in-line with my Sony headphones (which are very sensitive) and if I run the volume all the way up on the in-line level control, I get hiss from the rig, but it has nothing to do with the K3. Every device I listen to with my Sony phones the level control wide open (mixing boards, MP3 players, computers, stereo systems) produces hiss, and they all require AF gain be kept very low. Basically, since the phones are so sensitive, I'm listening to the inherent noise floor. The solution is simple. Throttle back the in-line volume control and the hiss goes away. Turn up the AF gain (to a normal level) and you get plenty of signal. Great sound, no hiss - That's my K3. - Keith N1AS - - K3 711 - -Original Message- My hearing aids do not have much response above 3.5 kHz.

You could answer your own question by ordering a pair and seeing if they work for you. If not, ship them back for a refund. I use a pair of $100 Sony over the ear headphones with my K3.

Re: [Elecraft] 43' Vertical and the K2 tuner
A few years ago, I was really on the 5/8 vertical bandwagon. I thought it was the cat's meow. The problem was that real world A/B testing did NOT show it to be any better than a 1/4 wave vert. I had a 5/8 wave vert for 15 meters. Ground mounted over 16 radials. An ATU at the base took care of the small impedance mismatch and RG-213 carried the signal to the rig. Hot stuff - or so I thought. I also had a 1/4 wave ground plane (4 radials) on the roof of my single story house. It was fed with RG-58. I spent a lot of time with an A/B switch listening to both antennas. You'd think the 5/8 with it's mondo low-angle radiation pattern would walk all over the 1/4 wave but it DID NOT. DX signals as the band was just opening or closing were sometimes stronger on the 5/8, other times on the 1/4. There was no clear winner. It was years before I found the answer. Apparently, that wonderful low angle radiation that we want out of the 5/8 wave antenna depends HEAVILY on the ground conductivity many, many wavelengths away from the antenna. Far out of the reach of any ground radial system, poor soil conductivity is sucking the low angle radiation down to near zero. Sure, over salt water it is fabulous, but for the vast majority, it just doesn't pan out that way. So, for normal soil, it seems the best height is something less than 1/2 wave. I run a 33' vertical with a Hustler 80M resonator on top. It resonates on 80 and 40 and does pretty well on those two bands. It also delivers the goods on 30 meters due to the remote tuner. On 20 meters and higher it isn't really all that impressive. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net on behalf of James Apple Sent: Sun 3/15/2009 9:26 AM To: Elecraft@mailman.qth.net Subject: [Elecraft] 43' Vertical and the K2 tuner After the ice storm of 2009, I'm looking for an new antenna.

Re: [Elecraft] K2 vs K3 ?
-Original Message- ... the K3 is a All in one rig with top of line features. The K2 was the former one. But I can make a qrp rig for $770 K2 kit instead of $1400 K3 semi-kit and I am an electrical engineer. Is there any good reason to go to the K3? VE3GYV John Absolutely, yes, there are many good reasons to go K3 over K2. I had a K2 and really liked it but wished it did some things better. The K2 s-meter left me rather unimpressed. CW sidetone quality was good but not great. I used an external AF filter to clean it up. The K2 display didn't give all that much information. The fan on the K2/100 is very noisy. I used an external fan to keep the rig cool so the internal fan would not turn on. The K2's SSB performance was good but no better. I run CW only so I didn't care, however. I upgraded to a K3/10 and absolutely love it. CW sidetone is very sweet. AGC performance is better (adjustable). The S-meter is better. Display is better. I have 2 key inputs (one for paddles one for manual key) instead of just one. The rig feels like a real rig rather than a very nice QRP rig. When you do your price comparison, make sure you're comparing equivalent rigs. The K3 comes with built-in DSP and does not need AF filtering. With the K2 you have to add the DSP or AF as an option. K3 covers 160 meters - optional in the K2. - Keith N1AS - - K3 711 - __ 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] So, anyone going to get more CW filtering?
Interesting. I had the opposite experience. I was on 40 meters yesterday afternoon for about 30 minutes. Signals were all pretty strong as Europe is just across the pond from my QTH. I did a lot of listening, comparing 1.1 KHz with 1.0 KHz and 550 Hz with 500 Hz. The difference of course, is that my 1 KHz and 500 Hz filters kick in. What I heard was a noticeable reduction in thumps, pops and AGC desensing as I stepped across the filter engagement boundary. There were a number of situations when I was at 550 Hz and could hear the other guy's signal being pumped up and down as my AGC was affected by someone 400 Hz away. I step down to 500 Hz, and the other guy's signal suddenly becomes smooth and consistent - no more AGC pumping. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Hachadorian Sent: Monday, February 23, 2009 9:52 AM To: Elecraft reflector Subject: Re: [Elecraft] So, anyone going to get more CW filtering?

We now have a US-built choice that gives performance that is ahead of it's cost.

Re: [Elecraft] ECO for SPOT Control
I think it is a good idea. I don't use CWT / auto-spot much and you've just made me realize my reason. Once I call CQ and someone answers, I don't change my TX freq and the auto tune feature does just that. Instead, I make sure CWT is off and use the spot tone to tune the guy in with RIT. The other reason I don't use CWT is that I don't like it taking part of my S-meter away. If CWT used the VFO-B area to show it's tuning display that would be great. But then I'd want to separate CWT and SPOT so I could turn on the CWT display but have the SPOT button still just sound the side tone rather than engaging auto-tune. Ah, too many options and possibilities. - Keith N1AS - - K3 711 - - Original Message - My suggestion would be to allow for the SPOT button to function as a RIT only control when the RIT button is engaged.

Re: [Elecraft] K3 Narrow CW Filter
NR in the K3 is a tool that primarily turns the volume down. Well, in all fairness, it does so selectively, turning down the noise more than the signal, but it does result in a reduction in signal even though the S/N ratio gets better. I'm thinking at 100 hz, there is so little noise for NR to process that it is easier for the signal to get treated as noise and to be attenuated. You may find you get the rig to sound better if you quit using NR and adjust the AGC slope or threshold instead. Set the AGC threshold higher and reduce the ratio a bit. This will help to generate more of a ratio between the signal and background noise.

Re: [Elecraft] K3- pace of development
In addition to risk and complexity, there are other factors that can have a bearing on what one would do next This list is a tremendous source of new ideas. Some of them are new novel and you want to stay open to those. Another factor is experience. The more we use our K3s the more we learn about what really needs to be fixed and what isn't so important. Some features that were envisioned (envisaged?) from the start may have seemed important but time has shown that they aren't so critical after all, but something unforeseen is. Combine that with the complexity and risk issues and you can have a seeming randomness to the changes. Of course, it could be that SW development at Elecraft is pretty much out of control. It could be that features are worked in random order depending on the whim of the implementer. It could be that things are done in an informal, undocumented, under-tested sort of way. It could be that the process relies almost entirely on the heroics of the individuals doing the work. In other words, they could be following the industry standard model for SW development. If so, I predict the rate of changes will slow as the code architecture becomes a limiting factor and as changes upon changes begin to take their toll. - Keith N1AS - - K3 711 - From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Monty Shultes Sent: Friday, January 30, 2009 11:04 AM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3- pace of development Having some experience with amateur repeater control software and other systems, it usually happens that some new features are particularly easy to implement while others are particularly hard.

Re: [Elecraft] Beware! (Learn by doing?) :-)))
Call me dense, but I'm not understanding why one would expect that turning AGC off would NOT result in a huge jump in AF output. AGC turns down RX gain - a lot. The only time there should be no change in AF output is when the RF input is so low that it hasn't reached the AGC threshold. Maybe other manufactures have coupled AGC on/off with AF attenuation, so if the AGC is off, AF output is automatically reduced by 20 dB or something. For this very reason, I always run with AGC on. Even when I want the rig to act like it's off, I leave it on, set to Fast and then just turn the RF gain down to put my signal of interest down near the point where AGC is doing very little. AGC is still on to protect me in case some big signal QRM or QRN shows up. - Keith N1AS - - K3 711 - -Original Message- The TenTec Orion allowed the user to shutoff the AGC @ will and the resulting big difference in audio was NOT THERE! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Why? For Ducking. (RE: Silly question - what is KEY OUT?)
-Original Message- I am puzzled about why you would want to connect your code practice oscillator to this output. If you want code practice, just put the K3 into TX TEST and you will hear sidetone from the K3 as you key it - no need for the external oscillator - but of course, if you 'just want to do it', then by all means go ahead with it. 73, Don W3FPR -- Why? To set up a ducking test of course :-) Here's the plan. Set the K3 MON level set to zero (no sidetone). KEY OUT connects to the code oscillator which feeds the sidechain input on my external compressor. Feed the K3 audio into the compressor main input and set the compressor to trigger when there is something on the sidechain input. So, when I send CW, the compressor hears the Heathkit oscillator and compresses (attenuates) the audio output from the K3. Using an external mixer, I can mix the compressed audio from the K3 with the audio from the code oscillator. The code oscillator will be constant level while the K3 audio will duck under it.

Hi Keith: The Key Out relay is only energized during transmission. This is what you would want for an amplifier. So for example if you turn your VOX off and press your key or paddle, the Key Out relay will not energize. If you turn your VOX on it will energize but you will also be transmitting. If you are in normal VOX control, the Key Out relay will stay energized longer than your key press based on your VOX delay setting. So it won't follow your dits and dahs. I suppose if you turn QSK on, the Key Out will follow the dits and dahs of your key presses or the internal keyer. It was mentioned that Key Out is available on the accessory connector. I use this output for an antenna relay and it is NOT identical to the Key Out jack we have been discussing. First it is a transistor output with limited current handling capability. You would need to construct a driver circuit to interface to it. Second, it IS present when you are not transmitting. It precisely follows the dits and dahs when VOX is turned off. When VOX is turned on it has the normal VOX delay applied. I pointed this out to the factory and Wayne wrote the following: This is how it works at present, but based on customer feedback, I may change it. 73, Mike K2MK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

You know Ron, it is actually ironic. I too have been reducing AF gain on my rigs for years but I find I do it more now than I used to and I think I know why. A few years ago I all but abandoned the keyer in favor of the straight key and bug. I'm back to manually generating CW and this manual generation of CW requires more of my brain. I need to hear my sidetone more than I used to. I need to clearly hear so I know when to end a dot or how long the dashes are supposed to be or when to do the next dot or dash. Some day when I'm no longer a beginner on the bug, I may not be so dependent on the sidetone, but for now I need to hear it clearly above the RX output or I'll mess up my sending.

[Elecraft] K3 feature request - I want Ducking!
Hey troops, I had an idea last night while in CW QSO with my K3. I've noticed that I always turn the AF gain down when I send CW. I have the side tone volume set to just the right level for the Spot function to work, but when I send CW I want to greatly reduce the distraction from the receiver. I still want to hear it, but not be distracted by it. That got me thinking about ducking. Boy, would it be cool if the K3 would duck the receiver under the CW side tone. I'd want it to be engaged only when sending (not for spot) and I'd like the AF gain reduction to be adjustable through a menu setting. I guess another way to implement this might be to have the side tone affect the AGC so when I send, my RX responds as if it were a real signal and the AGC kicks in to quiet the receiver. In this case, I'd want to set the amount of gain reduction and whether to use Fast or Slow recovery. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 feature request - I want Ducking!
Ducking is a commercial radio / sound industry technique of attenuating the music when the DJ talks. In the old days, the DJ at the radio station would just pan down the music volume whenever he spoke into the mic. These days, recording studios will use a compressor with a separate trigger (side chain) input. The compressor is set to attenuate 20 dB or so whenever there is something on the trigger input. You run the music through the compressor and feed the voice to the trigger. Then, when you talk, the compressor is activated, forcing the music to duck under the vocals. Close your mouth and a moment later the music rushes back to full volume. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ken Kopp Sent: Tuesday, January 20, 2009 11:56 AM What is ducking, as you call it here? 73!

No, the manual way to achieve this effect is to turn down the AF gain while you're transmitting. Sidetone is still there nice loud but the RX audio that you hear between elements is reduced. When you're done sending, you reach for the AF gain and turn it back up to the normal listening level. Now, imagine it was automatic. As soon as you send, the K3 turns AF gain down and leaves it down until a second or so after you finish sending, then it turns it back up to where it was. This way, while you're sending, the AF signal that you hear between dots dashes is quieter than when you're just listening. Is that any clearer? If not, ask more questions :-) - Keith N1AS - - K3 711 - -Original Message- I still don't understand this notion. For CW, don't you obtain this effect simply by turning down the sidetone volume?

Re: [Elecraft] K3 feature request - I want Ducking!
I would definitely view it as an option, and I'd want some configurability to it. But, with this feature, you'd still be able to run full QSK and hear between dots. It may be that really weak stations become harder to hear depending on how much attenuation you choose to apply to the RX signal. I'm thinking I may give it a try with my external compressor. I *think* I can get it all hooked up.

Re: [Elecraft] OH! I get it ... I think
Yes, it is to manage the din when operating full break-in mode! I use QSK because my CW timing gets messed up by semi break-in. I find myself waiting for the RX to open back up before I send the next word or trying to rush things to prevent the change over. I also send with bugs or straight keys so I need to truly hear what the side tone is telling me or I'll end up with sloppy CW. With a keyer, CW is much easier to send so I can tolerate more RX noise. - Keith N1AS - - K3 711 - -Original Message- From reading the posts about ducking it sounds like there are those of you who operate CW in a full break-in mode where you hear between code elements. Is this the case? If so, I can't envision how you tolerate the noise (!) and understand why you'd want to lower the level of the din between code elements. Other than the obvious desire to hear a BK between code elements, or to hear if the DX station in a pile-up has answered someone other than you, what's the reason for using this mode?

Re: [Elecraft] K3: ducking this topic
If I manually turn the RF gain down, then I've made it so only the loud stations are loud to me. Quiet stations (and the band noise) are all but gone. When a loud station appears, I hear them well. When loud QRM appears, I hear it well too which is exactly what I want to avoid. A similar issue exits with auto bandwidth changes. If the ducking system narrows the bandwidth to get rid of distractions, that's fine until QRM appears on your freq. and masks your sidetone. Instead, I want my RF gain to be high enough so that the weak and strong signals get some AGC action. Then, I want the AF gain auto-reduced by maybe 6-10 dB so that I can clearly hear my sidetone over the RX audio. With this configuration, I should be able to hear just about anything, weak or strong, that appears on my freq, but it won't be loud enough to mask my sidetone. I'm aware, yet still in control. - Keith N1AS - - K3 711 - -Original Message- This request is something I've never heard of and I am having a hard time imagining an actual use for it. If you turn the AF down (or duck it), then they station that you still want to hear must be relatively loud...or at least above the din. So in addition to Wayne's suggestion (which I agree with and was actually my first reaction), how about just turning down the RF gain for that QSO to the point where the noise (almost?) is out of the picture but the guy you want to hear, should he break you, is still audible? de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 1.0 KHz filter for CW - Needed?
I recently added this filter to my K3 to go with the 2.7 KHz and 500 Hz filters it already has. These are roofing filters so there is a question of whether or not they're needed - or even if they make a difference you can hear. I've spent time tuning the bands (mostly 40) with my filter width set to 1.1 KHz and 1.0 KHz, listening to the difference as the crystal filter is engaged. Is it needed? I'd usually no. Does it make a difference? Most definitely! I greatly prefer to operate with the 1.0 KHz filter engaged. I can keep my DSP bandwidth wider while still rejecting noise from 2 KHz away. The overall level of grunge in the receiver goes down when the crystal filter kicks in. I used to run with the DSP set to about 700 Hz to get the overall sound I wanted. With the crystal filter, I can open the DSP to 1000 Hz and get the same or more rejection of signals several KHz away. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If a button does one thing at one time and another some time later it can represent a moving target for learning and leave people confused. For that reason, I'd prefer to leave it the way it is.

That way, you could bypass the Manual mode if you never use it and the Notch button could be a simple On/Of switch.

RE: [Elecraft] K3 sensitivity + preamp: looking for wisdom
I think the theory is that the atmospheric noise is below the receiver's detection level so the noise you hear is generated inside the rig. Add a preamp and both the antenna noise and signal come up by the same amount bringing the antenna noise up to the detection floor and boosting the signal at the same time. The overall noise floor doesn't change much if any but switched from internal noise to antenna noise. The signal, however has come up and is easier to copy. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of DOUGLAS ZWIEBEL Sent: Monday, December 15, 2008 11:15 AM To: Elecraft Reflector Subject: [Elecraft] K3 sensitivity + preamp: looking for wisdom Hi... The following request for information is not specific to the K3 (or even to Elecraft). Please craft your response to be generic. Despite being an active ham/contester for over 40 continuous years (but not being an ee), I just do not understand how a preamp works. It is not a smart device, so how does it know to amplify the signal and not the noise? I first used a preamp way back when (1960's) when I was a teenager...it was an Ameco job. It was more fun than useful, because I could give out big S meter reports. Later, when listening in the noise became more important to my style of operation, I never could notice a difference between putting the preamp on and just turning up the volume (many rigs with built-in preamps too). Sometimes, turning up the AF gain worked better. So...HOW does a preamp help to bring a signal out of the noise without the use of some fancy computer algorithms backed by lots of computing power? Further, does a preamp really improve sensitivity? I have yet to find a signal that I could not copy (or hear) with any preamp on vs increasing the AF gain. PS...I am talking about HF. I know that lots of guys use a preamp on 160m with their beverages, so the effect must be real...right?

RE: [Elecraft] Request
Uh, actually, I don't think that is the best. Feeding the rigs through a stereo amp to stereo speakers will certainly give you more frequency response and may smooth the midrange some, but it will also give you much more high freq noise and low freq rumble. It may make signals harder to copy (although they'll sound nice when they're strong). Of course, who am I to talk. I use hi-fi headphones all the time. Even with hi-fi speakers / headphones, the quality character of the receive audio varies widely amongst ham rigs.

I asked him to contact authorities to report a fire and he said OK. That was it. I have no idea if the fire got reported or anything. It left me feeling very unsatisfied. I suspect, however the fire was already known about. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 - Numeric SWR Display
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Morrison Since I don't plan on hanging off the side of the tower to operate my station, isn't it more prudent to tune the entire system, flaws, feedline and all if my main concern is what SWR my equipment, in my shack, sees? No it isn't. If you're using 50 ohm coax and an antenna that is not 50 ohms resistive, you'll set up standing waves in the coax which will result in signal loss. Having a tuner at the rig will protect the rig from the effects of the standing waves, but the line loss will still be there. Far better is to have the tuner at the actual antenna feed point (or to adjust the antenna to be 50 ohm resistive). Then you'll have a happy rig AND minimal loss in the coax. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Kent Single Lever Paddles
Ya know, I don't by the movement counting that I sometimes see posted regarding single lever vs. iambic keying. Do we count muscle movement or joint movement? Is it one motion to squeeze or two? Do we count close and open motions or only closing motions? There is a lot of gray and subjectivity. I've even seen the counting applied unevenly (e.g. releasing is counted as a motion for iambic but not for single lever). I think the only sane way to look at is by looking at switch closures. How many motions and how many muscles are involved in closing the switches is a far more complex and subjective subject. Switch closures are very concrete and countable. Looking at it from a switch closure perspective, we have the letter A requiring 2 for iambic and 2 for single lever. I say that is one squeeze or grasp motion on iambic, others say it is 2 or 3 separate finger motions. Doesn't matter, we can both agree that it is 2 distinct switch closers. K requires 2 on Iambic but 3 on single lever. C requires 2 on Iambic and 4 on single lever. Regardless of the amount of joint / muscle movement, the iambic keyer requires less switch closures. The thing that makes Iambic tougher is that those switch closures must be precisely timed. That timing is easy at slow speeds and doable at moderate to fast speeds. At competition speeds, suspect the competitors use to single lever paddles because of the nearly impossible timing requirements of iambic, not because of any savings in motion. Having said all that, I do CW for fun, not efficiency. I know that Iambic requires less switch closures but I hardly every use the paddles. I use a bug or straight key most of the time simply because they're more fun. After all, this is a hobby - Keith N1AS - - K3 711 - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of n4lq In fact when you consider the entire alphabet, less finger movement is required with the single lever paddle. This came as a shock to me. Check the letter C. On a single lever we swing left, right, left, right. That's 4 movements. With duals, we (push left and hold), (push right and hold), (release left), (release right) for letter C. So we have the same number of movements with either paddle. Now let's do A. With single lever we swing left, swing right, release. 3 moves. With duals, we push left and hold, push right, release left, release right. 4 moves! It all happens so fast that you don't realize you are doing it.

RE: [Elecraft] WTB - Kent single lever paddle
A lot of people talk about how difficult squeeze keying is to learn. I sure don't want to lessen their position, but I confess I find it baffling. To me squeeze keying is very natural and intuitive. I went from a straight key to a keyer years ago without learning a bug or cootie key. Maybe that had something to do with it. I learned iambic squeeze keying when I was doing CW at 8 wpm. Maybe that had something to do with it. Many years later I learned to use a bug (lot's of fun BTW). It did take me a while, but that had more to do with learning to form dashes manually. Learning to not squeeze was the easy part. I guess after years (decades) of buggin', many ops find it hard to retrain the muscles and brain to send CW with a slightly different pattern. I'm interested in a single lever paddle so I can use it as a cootie (my next mountain to conquer). 73! - Keith N1AS - - K3 711 - -Original Message- From: David Ferrington, M0XDF I think I'd like to see Ultimatic mode too, I'm thinking I'll have to learn Iambic though, because most rigs don't support Ultimatic.

RE: [Elecraft] K3 competition from Icom?
If the price is in the $2000 range then it is competition for the K3. Will it out perform a K3? Probably not, but for a lot of buyers getting a full featured, well advertised rig from Ikensu just feels a lot safer than getting something from a smaller company. True performance only matters to those who care about it and even then only under tough conditions.

RE: [Elecraft] paddle/key combo question re: k1
I tried to do the same thing with the K2. I wired up a parallel junction box and plugged my paddles, straight key and bug into the box with one line going to the rig. I used diodes in the box as recommended to allow the manual keys to work with the K2's keyer. It worked but wasn't reliable as the keyer sometimes got confused. I going with 2 simple solutions: 1. Put the paddle away, use the bug and straight key only. 2. Buy a K3 (which has separate inputs for each). A third solution exists which also works wonderfully - use an external keyer and wire that in parallel with the manual keys, feeding the K1 in manual mode. - Keith N1AS - - K3 711 - -Original Message- From: Ben Harold - KG4BYN i can get it to work just fine in straight key mode, but the k1 can't handle the config for the paddles. note: the straight is in parallel with the dah side of the paddle. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Which rig is Elecraft's best value?
Pretty subjective, ea? Yes, the K3 is the best performer, but I wonder if it is really the most bang for the buck. Is it the best deal? Does it deliver the most fun per dollar? I'm actually thinking the award goes to the K2/10. You get to build it (really build it) and it's performance is simply great. The K1 is a great 2nd / portable / QRP rig but isn't really fulfilling enough to be a main or only rig.

RE: [Elecraft] u want nice audio?
I did the same as Don, but with CD players and power amps. I figured they were all the same and the high priced stuff was just over priced. Then I did something dangerous. I actually listened to good gear and compared it head to head with the great gear. I found out in a hurry that I was dead wrong. There really is a difference, a difference you can hear. I don't know if Monster Cable is hype or not, but I'm sure not going to write it off or embrace it without an A/B listening test. I've done the same with ham gear. Many say the TS-830s is a great sounding rig. I had one, tried it, compared it to the K2 and promptly sold the 830s. People talk about how great the TenTec stuff sounds. I've had it (Corsair, Omni C, V, Century 22, 21, Argo), used it, loved it. Then I foolishly compared it (Omni V) to the 830s. Boy was that Omni harsh sounding.

I think most times, adjusting offset while listening to the receiver and just having the sidetone pitch follow along would be just fine. But, if some crazy OT has decided to adjust RIT and SHIFT, then the received pitch will thrown off. Other than that, I think the idea is a grand one! I guess if I had the choice between adjusting pitch only while hearing the sidetone or only while hearing the received signal, I'd choose the latter - assuming I still get the pitch readout in Hz during the adjustment. 73 all! - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Sidetone Monitor Preference Opinions
-Original Message from Drew, AF2Z - Why would you want to vary the signal pitch? Because a different pitch can provide better copy under different reception condtions. But it's pretty hard to tell what that optimum pitch might be without listening to the signal as you adjust it, right? Now, you can vary the VFO in order to change the signal's pitch, but then you have detuned it. I want to vary the pitch of a signal without detuning it. The K3 can do this, only it doesn't let us hear the signal while doing it. --- Which brings us to the old fashioned way to adjust the pitch of the RX signal - RIT. It keeps the TX on the same frequency and as long as you don't adjust it too far, the signal will stay in the passband. Better yet, combine it with an IF Shift and you can go farther with RIT while keeping the signal where you want it in the passband. Do I remember correctly? Didn't the TS-930s have a CW Offset control that would adjust sidetone pitch, TX-RX offset and IF Shift at the same time? I used to want one of those rigs something bad. Then I borrowed one for a weekend and decided I liked my TenTec Corsair II better. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
