[Elecraft] K3 and general coverage
Bob Nielsen wrote: That lead to a question I hadn't considered before. How is general coverage in the vicinity of the first i.f. achieved? Bob, N7XY Hi Bob, As Greg (AB7R) mentioned, it isn't possible for the K3 to provide coverage in the vicinity of our first I.F., 8.215 MHz. We felt that this was a small price to pay, given our primary goal of offering an excellent ham-band transceiver. However, all other bands of interest for general coverage from 0.5 to 30 MHz can be tuned. If you have the KBPF3 option installed (on either or both receivers), its filters will automatically be switched in to cover the gaps between the narrow ham-band filters. But even without the KBPF3 you'll have useful sensitivity in shortwave broadcast segments near ham bands. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Simply connect them between the RX ANT IN and RX ANT OUT jacks. Then, whenever you select RX ANT from the front panel, the in-line band-pass filter would be switched in. Of course we hope that you'll find the K3's dynamic range high enough that such filters are not needed as often :) 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: HF Bandpass filters
Hallo, Of course we hope that you'll find the K3's dynamic range high enough that such filters are not needed as often :) High power bandpass filters also reduce the wide band noise which any PA will produce. To be effective in this role, the filters must be in line while the TX is doing its thing. This does not really have anything to do with the dynamic range of the RX but with the noisiness of the transmitter. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 and general coverage
What will the ATU do in general coverage mode? I guess the best thing would be to switch straight through, but would you have to go into a menu and do that manually whenever you tune to a non-ham band?

[Elecraft] Re: OT - 73 Magazine (was H mode mixer)
Hi Brian, Wayne was interesting to work for. He was aptly noted for being a cheapskate and it turned out that was true. OTOH, one time when I was up there he took me out to lunch and we had a great argument about the future of amateur radio. (Several people in the office dropped in a dead faint when they learned that Wayne actually bought me, an employee, lunch. :-) I was, of course, suggesting that digital communications was the future of amateur radio. He wasn't sure. Seems we were both at least part right because here it is 18 years later and we are only just starting to see changes in the communications landscape. I met him once very briefly. I was just a kid so other than him being the publisher of 73 and being reasonably nice, I can't say I knew him. He stirred strong emotions one way or the other in the older hams. The technical hams often dismissed 73 as a bunch of hoowie. Still a lot of VHF/UHF guys liked the publication. I certainly enjoyed some of the covers ;o) Anyway, he sure annoyed the hell out of everyone but you have to admit, he had an effect on what we do and how we do it. Never Say Die. 220, Use It or Lose It I still have the button for this somewhere... And speaking of digital communications, the loss of The Code as a gating factor is going to prompt a shift away from CW as the minimalist mode for HF. I believe that PSK31 is probably going to slowly take over that position as it can be done with equipment almost as simple as a CW rig and provides the same level of communications at similar power levels. (BTW, I am teaching code to my kids at school as I want them to be able to build the simplest radio possible to get on the air. I just don't think that CW will remain as the mainstay last resort communications mode.) You're probably correct in your assessment on digital modes. I think the K3 will go a long way in opening up digital modes for those of us who haven't tried them yet. Whether is PSK or another protocol, is to be seen. Judging by the numbers of participants in RTTY contests these days, it is a fast growing segment. Change is good, unsettling yes, but the possibilities are worth the uncertainty... 73, Julius n2wn ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] The Lowly Appliance Operator Ponders Filters
Thom, Let me try *my* recommendations for what I believe is your situation. First, you live in or near an urban environment, so I expect you have several hams near you with strong signals which might interfere - so if you want to operate easily on CW in the presence of S-9++ signal on the band, I would recommend a 400 or 500 Hz filter. You may even want an alternate selection of a 200 Hz width if the strong signal situation is really bad. If you want to operate digital modes (now made much easier with the K3 and possible even without a computer), I would want to have the 200 Hz filter for that operating mode (it will also serve as a narrow filter on CW) - there are just too many folks running higher powers on those modes who seem to pop up right next to the signal that you are trying to copy. Of course, with a narrow filter working digital modes, you will not be able to 'click and work' within the full 3 kHz waterfall width - you will need to tune the desired signal with the VFO into the more narrow filter width. I do that already with the K2 using narrow filters for PSK31, so for me it is no change from my normal operation. For the sub-receiver, ask yourself similar questions. 1) What modes will I be using the sub-receiver for? 2) How much de-sensing of the receiver from strong nearby am I willing to tolerate? When you have the answers to those two questions, you will be able to decide what filter widths are needed there. Notice that the reasons for choosing the filters are different than simply how narrow a filter do you want to use - the DSP certainly can reduce the bandwidth to a very narrow slice, but what the hardware filters do is to keep strong undesired signals out of the DSP. You may never notice the lack of a narrow filter if you never try to work a weak signal or if you never encounter a strong interfering signal near your operating frequency (static noise is an 'interfering signal' too, but is broadbanded) - but for operation on a crowded band or in the midst of static, the narrow filters will clean it up easier than any other method and allow you to work those weak ones. 73, Don W3FPR Thom LaCosta wrote: When technical smarts were issued, I had to be hiding behind the door.

[Elecraft] OT: balun rating exceeded
The following happened to me a few years ago as a brand new ham in my pre-Elecraft days and I wonder if anyone can explain to me the details. I apparently had high swr and exceeded the rating on my balun. It suffered accordingly but didn't completely fail. The result was when I transmitted cw on 40m an internal fuse would blow in the stereo which was on in the next room room. It took two go rounds before I caught onto the cause and effect... A new better balun cured the problem. At the time I had a Zepp (135') and 4:1 balun at the house entrance. I assume the ruined balun was emitting all sorts of RF that the stereo amplifier picked up, tried to amplify, and couldn't. But I don't understand exactly what would make it draw that much current. Can someone enlighten me? By the way, since then I put up a dipole, halfwave for 160m, about 200' behind the house. That's what I should have begun with. Thanks!

RE: [Elecraft] The Lowly Appliance Operator Ponders Filters
Why not just order the basic ssb filter (2.7 KHz) and see how it does. If you want to use FM or AM, get those filters as you need them to TX using those modes. I expect the 2.7 filter will do fine for everyone other than the DX and contest guys. I suspect the K3 with the 2.7 filter will work as good or better then most other $2000 to $3000.00 radios out there. When I do my casual CW listening on (mostly) 80 and 40 meters, I have the K2 in 1.4 KHz and don't often have any problems with copy. The K3 2.7 KHz filter is just the first filter, unless you have real strong local signals close, you likely wont have any problems. Now if you often find yourself working a signal and having a real strong signal very close, you might think about something narrower... I live in a very suburban setting, and rarely have anything strong close to what I am listening to. Last night I was surprised to copy a slow signal on 40 meters that was about 40 over, I wrote the call down, but its at home...I must look it up. I don't think the bar graph ever went up so high before! I did NOT notice any problems from it on other signals. Last night was a great slow code night for some reason, slow for me is 10 to 15 wpmI STILL have to count some of the numbers! Filters seem like they would make great birthday or fathers day gifts!

[Elecraft] 73 Mag

He wasn't sure. Seems we were both at least part right because here it is 18 years later and we are only just starting to see changes in the communications landscape. Anyway, he sure annoyed the hell out of everyone but you have to admit, he had an effect on what we do and how we do it. -- You say Wayne Green was a cheapskate. I take your word for that. My impression of him was that he was something of an egomaniac as well--but very smart! I got a dose of this at an early age. I was stationed in Berlin ('60 to '62), and one of my duties there was to run the MARS station. When The Wall went up, we were suddenly inundated with lots of visiting firemen, and Wayne apparently wanted to be one too. I got a message that Wayne and his wife would be making a quick overnight visit to Berlin two days hence, and could I make a hotel reservation for them. The message said he would also like to visit our MARS station. So I made him a reservation at one of the nicer hotels in Berlin, and passed the word to the other 5 or 6 hams in the 592 Signal Co. that Wayne would be visiting. I also invited several of the local DL's, and a half dozen or so showed up. Wayne came, visited with us for only about 20 minutes or so, and then left. I never heard from him again, but later I did hear that he had expected something more formal. I'm not sure what he really expected, particularly on such short notice, but what can I say. I was a little miffed about that for a while, but being only 19, perhaps I was a bit naive as well. But Wayne was a rare fellow to say the least. And he was very entrepeneurial as well. He was quick off the blocks to get into the computer magazine business, and you may recall that when CD's (music) first came out he was Johnny On The Spot with a pretty darn good magazine for that as well. But he loved controversy. Half the stuff he editorialized about in 73 had nothing to do with ham radio. I don't know if he really believed all that stuff he was ranting about, but I wouldn't have wanted to debate him on any of it either. At times I couldn't tell if I was reading 73 Magazine or The New Yorker! It was hard not to admire the guy though. I'll bet he was interesting to work with.

I think even a perfectly functioning, perfectly shielded balun *at the antenna feedpoint* might be somewhat moot unless the dipole is perfectly straight, and the feedline is run exactly perpendicular to the dipole (to equalize coupling to either side of the antenna). By the same token, I've often wondered just how balanced a balanced feedline really is under similar circumstances. Maybe twisting the line might help improve transmission line balance. Maybe using a tuner that can compensate for any voltage/current imbalance might be advantageous, as well. There are many complicating factors when it comes to antenna installation and operation.

[Elecraft] K3 VS. Omni VII
I am a long time Ten Tec user interested in upgrading. I have never used a piece of Elecraft equipment but am very intrigued by the K3. Are there any Elecraft users who can give me some advice about what I may expect from the K3 vs the OMNI VII since they are both near the same price? Thanks, Anthony AA9OC -- Anthony, I doubt a fair comparison can be made without hands on with both radios. But I strongly suspect that the K3 will outperform the Omni VII, at least in most areas. Personally I think Wayne and Eric had the Orion clearly in their crosshairs when they designed the K3. The Omni VII will surely not be equal to the Orion, and the K3 will probably give the Orion a very good run for the money. There have already been inferences that the K3 specs will be better than the Orion. I'm betting they will be. If Ten-Tec gets its act together on software, the Omni VII will probably be a very good radio. I've been a Ten-Tec fan for a long time, and currently have an Orion II. I really like it! But I could not resist the K3, and I doubt I will be disappointed. You may spend as much on a K3 as you would an Omni VII, but you won't have to pay the price of an Orion II to get something that will probably beat both of them. But if there is any doubt in your mind, you might want to wait for the tale of the tape. I suspect that QST (and others) will be all over the K3 as soon as it hits the street. It shouldn't take too long thereafter to get some really meaningful comparative data. One thing for sure though, as good as Ten-Tec support has been over the years (notwithstanding all the software issues), you won't get better support than you get from Elecraft. And if for some reason you buy a K3 and don't like it, I'm reasonably confident you could sell it for little, if any, loss as the demand is apparently quite high. So, if it fits your budget, go for the K3! Dave W7AQK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Why I don't want a K3
Ever since the K3 was announced this reflector has been buzzing with questions and speculation about the K3. It has been dissected, picked apart, put back together, etc. I feel like I know it inside and out and I don't even own one yet! In fact, I'm pretty bored with it. I'm about ready to put my imaginary K3 up for sale. It does all the stuff you guys say it does and even better. So, what's next? :-) Just kidding! We are all like a bunch of little kids about a week before Christmas. I'm still building my K2 and I already want a K3! It will be interesting to see what kind of a ripple the K3 creates in the HF market. Will the other manufacturers respond? When? Will they up the bar a couple of notches? Have they been holding back? Will they re-think their designs? Will they adopt the modular approach? It's going to be interesting. I think Elecraft has really opened up the flood gates and I hope that they are very successful. I know that I will be ordering a K3 for sure. Gary, N7HTS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 resale value?
One of the beautiful things about the K1 / K2 / KX1 series is that they assembled kits sell for at or near new kit price. So a schlep like me can buy a K2, assemble it, use it a bit and get my money back out of it. These are the only rigs that allow that sort of return. Enter the K3. It's not really a kit, at least not to the same level. I'm expecting the resale value of a K3 will be similar to the resale value of any other commercially produced ham rig. Pay $2000 for a new rig, sell it 1 year later for $1500. So, the Elecraft entry path will be to start with a K2 (or K1), see if you like their stuff, then, sell it (getting your $$ back) and buy a K3. I also wonder what will happen to the used value of a K2 as we'll see an increase in available rigs. - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] OT: balun rating exceeded
What usually happens under those conditions may not damage the balun but does cause lots of RFI: the balun turns non-linear! When the magnetic flux saturates the core it heats and its magnetic properties change dramatically. That produces a non-linear transfer function. Non-linearity is the hallmark of a good mixer! So your balun starts making all sorts of unintentional RFI that wasn't at the output of the transmitter. Under such conditions the core is absorbing a lot of power too. Had you touched it, you'd probably have found it noticeably warm, perhaps even hot, possibly hot enough to blister your finger. At the extreme, the core will heat and crack, ruining it and the balun. But that doesn't always happen. Another temporary failure mode is arcing. That may be more obvious since you may hear it if the balun is nearby. Most baluns are not made to handle really large RF voltages. There isn't enough spacing between leads and terminals for that. The insulation on the wires isn't rated for high voltages. So, when you have it at a voltage loop and crank up the power, it's easy for an arc to occur across adjacent leads. If it's through the air between metallic conductors usually no harm is done. Often it's through the insulation of adjacent wires or across a PCB. In those cases a carbon trail is formed that will have to be removed before the balun will work properly again. The bottom line is that modern baluns are NOT designed to be used in systems with a wide range of impedances. You can get away with using a balun in a multiband doublet, Windom fed with parallel lines, G5RV, etc., only when those antennas happen to provide a reasonable impedance at the balun: neither too low (which would produce high RF currents) or too high (which would produce high RF voltages). Many years ago many of us did use baluns in such systems quite successfully. They used air core coils. Air does not saturate magnetically. They had large enough spacing to avoid arcing at high RF voltages. Such baluns commonly measured a foot square, or larger, by nearly a foot deep. They were generally mounted on the wall well away from anything that might draw an unintentional arc from the coils - such as the operator! There are times when size does matter!

A new better balun cured the problem. At the time I had a Zepp (135') and 4:1 balun at the house entrance. I assume the ruined balun was emitting all sorts of RF that the stereo amplifier picked up, tried to amplify, and couldn't. But I don't understand exactly what would make it draw that much current. Can someone enlighten me? By the way, since then I put up a dipole, halfwave for 160m, about 200' behind the house. That's what I should have begun with. Thanks!

Re: [Elecraft] 73 Mag
A common thread running through the life of most authors is their difficulty getting paid by publishers, being stiffed by unscrupulous publishers, etc. The amount is small, typically on the order of $50 or so per published page in the small magazine world, based on my experience, at least, but it's still difficult to get paid, or if the publisher is honest, getting paid on a timely basis. The ARRL is a welcome exception to this. I'm glad I don't have to earn a living writing for amateur radio journals.

Re: [Elecraft] 73 Mag
Doug, Ah, how well I relate. I wrote 4 articles for 73. It took a year to get payment for the first two and then only because Wayne wanted my next two. These last two I never got a dime for because 73 folded. I figure I made about $5 and hour for my articles. Hardly worth it. There was a time when Wayne seem pretty rational. But, somewhere in the 90's his editorials became an intellectual disgrace. Not to mention his constant berating of people who are not rich like me and his unending self-aggrandizement. His agreement with René and the absurd assertion in his book that the moon-landing was a hoax was, I imagine, the last straw for many. Still, Wayne did a lot to move VHF FM into the mainstream. This and many other things were important and significant contributions of his. 73, Doug -- K0DXV [EMAIL PROTECTED] wrote: Back in 1956 when I was a senior in high school I wrote an article for CQ describing a plate modulator I homebrewed for my Heath AT-1 (ah, the memories).

Re: [Elecraft] K3 Panadapter / SoftRock
Is it really as simple as changing the crystal in the SoftRock 40 from 7.038 to 8.215 to provide a band scope for the K3? Seems too easy. I use the Rocky program to manage the display. You do NOT want an 8.215 MHz crystal (or 4 x 8.215 MHz) for the softrock if you attach it to the IF pickup of the K3 for a bandscope. The softock has very little isolation of the L.O. to its antenna input, and you'll inject a lot of energy directly into the IF of the K3. You want the softrock injection on the LOW side of 8.215 MHz. I can't tell you what the best frequency might be because I don't know, but I suspect 8.200 or thereabouts. You may also want/need an isolation amplifier to ensure the reverse coupling back into the K3 is at a very low level. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I figure I made about $5 and hour for my articles. Hardly worth it. There was a time when Wayne seem pretty rational. But, somewhere in the 90's his editorials became an intellectual disgrace. Not to mention his constant berating of people who are not rich like me and his unending self-aggrandizement. His agreement with René and the absurd assertion in his book that the moon-landing was a hoax was, I imagine, the last straw for many. Still, Wayne did a lot to move VHF FM into the mainstream.

[Elecraft] RTTY vs. PSK31 (was: OT - 73 Magazine (was H mode mixer))
Whether is PSK or another protocol, is to be seen. Judging by the numbers of participants in RTTY contests these days, it is a fast growing segment. Change is good, unsettling yes, but the possibilities are worth the uncertainty... CW remains a mainstay because it is an efficient mode. You can communicate with very low power levels which makes QRP reasonable. RTTY is not nearly so efficient and requires much more energy per bit to get good copy. It forces you into more QRO operation. PSK31 is as narrow as CW which lets you use narrow filters to lower the noise energy in the passband. It also incorporates forward error correction which allows it to still give good copy with very marginal signals. Now that is not to say that PSK31 is the be-all and end-all for casual QSOs but I personally think that it is the first of some very interesting modulation schemes that will provide the same level of performance as CW. And since new hams don't have to know the code anymore ... 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 resale value?
Kieth, Let me speculate a bit on why the KX1, K1 and K2 hold close to the new kit prices - Elecraft has done with those rigs something almost unheard of from manufacturers - every one of those rigs is fully upgradeable to the equal of the very latest level. Oh, yes, there are some differences between the pre 3000 SN boards and the post 3000 SN boards, but all the earlier kits can be upgraded none-the-less. My Field Test K2 SN 00020 is stuffed with all the possible options and is currently at the same electrical equivalent of SN 6000, and to tell the truth, one would have to know where to look to see an obvious difference in the parts placements. Other manufacturers would likely release a new model of the base rig (Omni vs. Omni II for example), and not offer any kind of upgrade path (at any cost). In fact, they often drop support of older models after a few years - no parts available. So since an old K2 is as valuable as a new one (OK, you may have to shell out for some upgrade kits if you buy an unupgraded older K2), I believe that is the main reason the prices stay high. I don't think anyone knows how hardware upgrades for the K3 will be handled, but I expect to see a parallel path to the K2 history. 73, Don W3FPR Darwin, Keith wrote: One of the beautiful things about the K1 / K2 / KX1 series is that they assembled kits sell for at or near new kit price. So a schlep like me can buy a K2, assemble it, use it a bit and get my money back out of it. These are the only rigs that allow that sort of return. Enter the K3. It's not really a kit, at least not to the same level. I'm expecting the resale value of a K3 will be similar to the resale value of any other commercially produced ham rig. Pay $2000 for a new rig, sell it 1 year later for $1500. So, the Elecraft entry path will be to start with a K2 (or K1), see if you like their stuff, then, sell it (getting your $$ back) and buy a K3. I also wonder what will happen to the used value of a K2 as we'll see an increase in available rigs. - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Roofing Filter Overkill
N2DTS wrote: The K3 2.7 KHz filter is just the first filter, unless you have real strong local signals close, you likely wont have any problems. This is very good advice. Some may forget that the DSP filters in the 2nd IF are the primary means for achieving selectivity. The 1st IF roofing filter is simply preventing issues caused by very strong signals from reaching the DSP stage. Now if you often find yourself working a signal and having a real strong signal very close, you might think about something narrower... I would suggest not adding filters unless you ACTUALLY experience problems. Since many of us tend to be closet engineers, we tend to overkill potential problems that will most likely never exist. If you actually do experience a problem, ordering a filter is easy and you'll have it in 2-3 days via Priority Mail. I'll repeat why a 200-250 Hz filter is most likely a good example of overkill in our real world of transmitter phase noise, key clicks, etc. Let's assume you have a S9+40 dB signal spaced 200 Hz from your operating frequency that is causing desensing, either BDR or analog AGC activation (i.e. pumping). First let's try Inrad's 400 Hz 8-pole filter below (identical for K3): http://www.qth.com/inrad/graphs/701.gif The graph is not quite centered but the 6 dB bandwidth is 435 Hz (i.e. +/- 218 Hz from center) so the rejection at 200 Hz from the center is just under 6 dB. We now have a S9+34 dB signal at 200 Hz away from us. Possibly some help if it prevents the signal from activating analog AGC (assuming the DSP ADC limit is around S9+35). Next let's try a 250 Hz 4-pole filter like Inrad's for Orion II (we don't yet have a plot of K3's 200 Hz 5-pole but I expect it may not differ significantly in shape factor from Inrad's below). http://www.qth.com/inrad/graphs/353.gif Because the 6 dB bandwidth is actually 562 Hz, it will actually have *less* rejection at 200 Hz than the 8-pole 400 Hz above. OK let's try another. Inrad's 250 Hz 8-pole (again identical to that in the K3). http://www.qth.com/inrad/graphs/708.gif The 6 dB bandwidth is actually 370 Hz, so it has the best rejection at 200 Hz spacings (but only marginally better than the 8-pole 400 Hz above which has a 6 dB bandwidth only 65 Hz wider (435-370). In the real world, will ANY of these filters really allow us to operate 200 Hz from an S9+40 dB signal? The simple answer is NO. Why? Because the transmitted phase noise (for only a steady state carrier) far overrides desense issues. Furthermore, when the carrier is keyed, we must then add the effects of key clicks. We actually are pressing our luck if we try to operate 500 Hz from such a strong signal, and I doubt very few on this list have ever done that unless they are very serious contesters. Bottom line...we can add the world's best filter but it will NOT solve the fundamental problem of transmitter phase noise and key clicks, which become the limiting factors at very close spacings. Today Orion has the best close-in phase noise performance and CW waveform shaping of any commercial rig, but its sidebands are down only about 70 dB at 1 kHz spacings. Move closer and it is more like 30 dB down at 200 Hz spacings. What good does it do if we could achieve IMD of 100 dB and BDR of 140 dB at 200 Hz spacings when the interfering transmitter signal itself overrides the receiver's performance by at least 60-70 dB? That's pure overkill and a waste of money IMHO. 200-250 Hz roofing filters might make us feel good but, in the real world of transmitted phase noise and key clicks, they will not allow us to operate significantly closer than we could with 400-500 Hz filters. And, as we saw above with the 4-pole 250 Hz, we may want to see all filter plots before we decide which is actually better. I ordered my K3 without any optional filters, and I may even swap out the 2.7 kHz 5-pole once I see complete IMD/BDR performance data and the actual filter plots. 73, Bill W4ZV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Instant Gratification
Well, Lee, I see a different side to it. I think we're all quite aware that the K3 isn't here yet and is an unproven item. Still we have indication of how it will likely end up. All the chat / speculation / conjecture has spurred a lot of solid technical discussion which has been great on the list. We've learned about receiver design and about good and bad points of other rigs. Good stuff. And some of us fully consider all the aspects of something before buying. When buying a new car, we'll look at safety, dimensions, cargo capacity, towing capacity, EPA estimates and yes, even resale value, to gain a better overall picture of what we're spending our money on. We'll even consider those things for a model that hasn't quite made it to dealer's showrooms yet. Failure to do means you'll be set up for a surprise when you buy the item and find it won't tow your trailer or you can't fit your guitar into the trunk or you can't get in and out of the back seat. The more you learn, the better informed you are and the more likely you are to have a realistic expectation of what the item will and won't do. As to these discussions being pointless, there are a lot of different people chiming in on a lot of different topics. There is excitement in the air and many people are tuned in. I'd say the discussions are far from pointless. Some of us (not me) were planning to buy a rig but now are going to wait to see what the K3 offers. Were it not for the discussions, they may have gone ahead and ordered. I do agree that we have to be careful when we say what will and won't be but again, I don't think any of are really thinking there are any guarantees at this point.

Again, I said salient But come onthere has to be some point that is good for the discussion, not some pointless blather and speculation. Lee - K0WA Gee - I wonder how the K3 will perform against a SB-101? or Does the K3 have a filling hole for more QSOs? In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense.

Re: [Elecraft] RTTY vs. PSK31 (was: OT - 73 Magazine (was H mode mixer))
In my humble opinion, I would say PSK, generally, has it all over RTTY. Communication can be maintained with very marginal signals, and very nearby signals (unless they are dirty or overpowering the receiver's AGC system). I have used a lot of RTTY systems over the years and they require MORE bandwidth, more power for effective communication (generally), and subject nearby signals more interference (generally). The largest bug I have found in the PSK system is that it is mangled by propagation phase shifts caused by auroral disturbances even though audibly, the signal sounds OK. I consider this acceptable as it (PSK31) seems to get through much more efficiently than RTTY with less power. Speed in this case not a factor in keyboard to keyboard QSO's. I can see no sense in using MORE bandwidth than a PSK31 signal to convey normal QSO information. Other modes capable of data and image communication in addition to normal keyboard QSO's wind up being gross overkill and use spectrum space a lot more inefficiently. Spectrum space for CW, digital modes is shrinking from demands made for voice and wide data modes. Therefore it would behoove us to contrate our efforts on the narrowest digital mode that will give satisfactory communication in these days of decreasing spectrum space. An amazing amount of use is being made of just a 3-5 Khz. sub band for PSK operations on most bands from 80-10 meters. It amazes me why this mode isn't replacing RTTY, and remains a popular FSK mode. It would be like comparing effectiveness of SSB voice mode to the older AM voice mode. I can't see people changing over to AM, even as a fad, over SSB operations. It's starkly obvious which is generally superior! My two pennies worth on this thread. 73, Sandy W5TVW - Original Message - From: Brian Lloyd [EMAIL PROTECTED] To: J F [EMAIL PROTECTED] Cc: Elecraft Discussion List elecraft@mailman.qth.net Sent: Tuesday, May 15, 2007 1:09 PM Subject: [Elecraft] RTTY vs. PSK31 (was: OT - 73 Magazine (was H mode mixer)) Whether is PSK or another protocol, is to be seen. Judging by the numbers of participants in RTTY contests these days, it is a fast growing segment. Change is good, unsettling yes, but the possibilities are worth the uncertainty... CW remains a mainstay because it is an efficient mode. You can communicate with very low power levels which makes QRP reasonable. RTTY is not nearly so efficient and requires much more energy per bit to get good copy. It forces you into more QRO operation. PSK31 is as narrow as CW which lets you use narrow filters to lower the noise energy in the passband. It also incorporates forward error correction which allows it to still give good copy with very marginal signals. Now that is not to say that PSK31 is the be-all and end-all for casual QSOs but I personally think that it is the first of some very interesting modulation schemes that will provide the same level of performance as CW.

Hi Don; I sent my Omni VI in for a + up-grade. They couldn't make the changes as there are more up-grade parts (filter boards) in stock. Pete kn6bi -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm Sent: Tuesday, May 15, 2007 1:40 PM To: Darwin, Keith Cc: Elecraft Subject:Re: [Elecraft] K3 resale value? Kieth, Let me speculate a bit on why the KX1, K1 and K2 hold close to the new kit prices - Elecraft has done with those rigs something almost unheard of from manufacturers - every one of those rigs is fully upgradeable to the equal of the very latest level. Oh, yes, there are some differences between the pre 3000 SN boards and the post 3000 SN boards, but all the earlier kits can be upgraded none-the-less. My Field Test K2 SN 00020 is stuffed with all the possible options and is currently at the same electrical equivalent of SN 6000, and to tell the truth, one would have to know where to look to see an obvious difference in the parts placements. Other manufacturers would likely release a new model of the base rig (Omni vs. Omni II for example), and not offer any kind of upgrade path (at any cost). In fact, they often drop support of older models after a few years - no parts available. So since an old K2 is as valuable as a new one (OK, you may have to shell out for some upgrade kits if you buy an unupgraded older K2), I believe that is the main reason the prices stay high. I don't think anyone knows how hardware upgrades for the K3 will be handled, but I expect to see a parallel path to the K2 history. 73, Don W3FPR Darwin, Keith wrote: One of the beautiful things about the K1 / K2 / KX1 series is that they assembled kits sell for at or near new kit price. So a schlep like me can buy a K2, assemble it, use it a bit and get my money back out of it. These are the only rigs that allow that sort of return. Enter the K3. It's not really a kit, at least not to the same level. I'm expecting the resale value of a K3 will be similar to the resale value of any other commercially produced ham rig. Pay $2000 for a new rig, sell it 1 year later for $1500. So, the Elecraft entry path will be to start with a K2 (or K1), see if you like their stuff, then, sell it (getting your $$ back) and buy a K3. I also wonder what will happen to the used value of a K2 as we'll see an increase in available rigs. - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Good points Sandy, but you know there are a lot of guys with old Type 47 and 33 mechanical printers out there who enjoy firing them up and hearing them rattle the windows of the shack pounding out TTY on paper by the hour.
