Re: [Elecraft] Calling the K3 USERS GROUP on SSB
Folks, I think you are being a bit unfair to Windy. The guy wants to establish a K3 user's group. What's wrong with that? Perhaps his announcement was a bit cavalier, but I took it to be an attempt at humor (i.e. saying brasspounders should get a life, etc.). I have no idea who Windy is, or whether he can successfully organize a net that substantively holds my interest. I'm not even sure I'll participate. But I'm not going to assume on the front end that his motives are ulterior or inappropriate. At least he's trying to show a little initiative! Now, I am assuming Windy intended this to be a net where there was actually some substantitive discussion about the K3--it's pluses and minuses, operating issues, etc. Maybe it would be a chance for others to put their K3 on the air and get on-the-air advice about your setup. If that's the case, I can understand why he preferred not to confuse things with other Elecraft rigs. They are different, and have many different issues. But if it's just going to be a check in and say howdy type net, with no dedication to substantive discussion of the rig itself, then I agree that there isn't much justification to exclusions. But I also got the impression that you didn't have to have a K3 to check in, he just wanted the topic to be about the K3. I would further assume it would be an excellent opportunity for non-K3 owners to ask questions about the K3, or even about comparisions with other rigs--there just needs to be some nexus to K3's. There are all sorts of reflectors, etc. that deal with specific rigs. There are also some groups that deal with brand names, not just specific models. I think those all have their individual purposes. If someone just wants to have a generic Elecraft net, go ahead and establish one! Kevin has a fine CW net like this, although there is not much discussion about the various rigs that goes on during that net. So if you want to do this on SSB, I think that's fine. I just don't understand why folks go off half-cocked because someone wants to do something with a specific purpose. Windy apparently wants to talk about K3's. There is a lot to talk about, you will have to admit that. If you have a K3, want a K3, or are just interested in K3's, you would presumably be welcome to participate. I don't see a thing elitist about it, and I think he has clarified that in subsequent follow-up posts. I suppose if you think making the topic that narrow would not fill up the time allowed, it would be appropriate to point that out as your opinion. But since he is the one setting it up, I think it's his privilege to establish the agenda. I can certainly see how making the agenda too broad could be a distraction. He's simply inviting anyone else with a similar interest to participate. If your interest is broader than that, it probably is appropriate to find, or establish, a different venue. But for crying out loud, don't shoot the guy just because it doesn't meet your goals. You can certainly offer your suggestions, but don't throw spears at him! That's just plain negative thinking. Personally, I choose to assume his intentions are innocent and honorable. If his idea is a bust, he will find out soon enough. People won't show up for the party.

Re: [Elecraft] re: ARRL K3 review for Apr QST posted [TX IMD]
Thanks for the explanation Wayne. Dave Wilburn K4DGW K2/100 - S/N 5982 wayne burdick wrote: AB2TC - Knut wrote: Receiver results as expected, great. Disappointed with the transmitter IM, even at reduced power. A couple of comments on this, Knut. The league measured around -30 dBc worst-case when using the K3's highly accurate internal 2-tone generator (as did we). 12-V class radios are rarely better than -30 dBc on their worst-case band, and some are in the -23 dBc range, based on a survey of QST reviews from the past 5 years (more on this below). QST's published -27 dBc figure was measured with an external 2-tone generator via audio injection (this is the ARRL's reference method). This was disappointing for us, since we were expecting -30 dBc. The fact that they did see -30 with our internal 2-tone generator suggests that the SSB setup procedure in the K3 manual, and/or our SSB ALC algorithm, could be improved. We're looking into this already. Any improvement we make in firmware (or hardware, for that matter) will immediately be made available to all K3 owners. Transceivers that are very heavy (including some that probably have their own zip code) can incorporate a large internal or external power supply that provides greater than 12 V (typically 24 to 50 V) for improved PA-stage overhead. Some can even be operated class A, which I applaud. But neither greater weight nor class A operation near 100 W is possible in the K3's form-factor. At just over 8 pounds, it's portable. This *was* a design goal :) QST always publishes the worst-case per-band IMD number, in our case on 12 meters. On most bands, IMD is much better than this by any measurement method, exceeding -40 dBc in some cases. The worst-case IMD is also much better if you're running less than 100 W. So, anyone driving an amplifier that requires less than 100 W to reach full power will see even better numbers. My question to Elecraft is: If this had been a factory assembled unit, would it have passed QC at Elecraft? There is no difference in measurement method or performance between kit and assembled. The 10-W and 100-W modules are all pre-tested before they go into either the radio or the parts kit. The RF boards are also 100% pre-tested, and any problem with IMD would show up immediately. But IMD is generally a non-issue for the RF board, which at the 0-dBm transmit drive point shows worst-case 3rd-order IMD of -45 to -55 dBc. I'm sure this unit passed our QC tests, given that the League found -30 dBc worst-case with the internal 2-tone generator. 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] K3 AM Broadcast Band Reception
John, AM reception in SSB mode will allow you to receive with good quality (up to 2.8 kHz of audio passband). With the 6 kHz filter, you will be able to receive an audio passband up to 3kHz wide in AM mode. The audio should sound the same either way So the answer is - if you want to avoid the hetrodynes while tuning in SSB mode, yes, you will want to tune in AM mode and that will require the 6 kHz filter - if you don't mind the hetrodynes (only while tuning), then the 2.7 or 2..8 kHz filter will be fine. Once the AM station is properly tuned, there should be no hetrodynes heard. The 6 kHz filter is required for AM transmission. 73, Don W3FPR John Silva N3AM wrote: In addition to the KBPF3 General Coverage RX module, is the 6kHz filter required for improved quality AM reception?

RE: [Elecraft] K3 AM Broadcast Band Reception
That's true when speaking of the heterodyne between the BFO and the carrier of the AM signal when receiving an AM signal in SSB mode. In either case, if you have a second signal close enough to the frequency of the desired one so it produces a heterodyne in the audio range, it'll produce a heterodyne in either AM or SSB mode. For an AM Ham rig with a well-shaped audio response that is limited to about 3 KHz, there's little difference between the 2.7 or 2.8 kHz filter in SSB mode and the 6 kHz filter in AM mode. However, for receiving broadcast signals that use a full 5 kHz or more of audio bandpass, superior reception is provided by using the 6 kHz filter in SSB mode, since that allows audio frequencies up to 6 kHz to pass through. That's the way I do most SWL-ing with the K3, since using SSB mode also avoids the problems with selective QSB that shifts the phase and amplitude of the carrier relative to the sidebands, producing a lot of distortion. I find the audio quality in SSB mode with the 6 kHz filter is superb on AM broadcast stations. Since broadcast stations stay within a Hz or so of an even frequency in kHz, and it's simple to calibrate the K3 readout to be within a Hz or so of the indicated frequency, it's easy to tune them in perfectly, even if you don't have the ability to hear audio tones well. Ron AC7AC -Original Message- John, AM reception in SSB mode will allow you to receive with good quality (up to 2.8 kHz of audio passband).

The K3 Owner's manual describes the accessory connector pinout.

I confess that I often am confused by pin layout pictures, because it matters whether you're looking into the connector or looking from behind where the wires are fastened. It's easy to get backwards. http://en.wikipedia.org/wiki/VGA_connector When my TTD Band Decoder arrives, I plan to run multiple cables into the K3 accessory connector, and introduce a molex connector into the band decoder cable to make it easy to disconnect. If I ever change the band decoder cable length, there may eventually be two molex connectors in that path.

[Elecraft] K3 SSB transmit IMD
I'm a little unsure about what the ARRL is saying in their evaluation of the K3's transmit IMD. Here's what I THINK they are saying: ARRL's K3/10 measured -23dB worst case. They contacted Elecraft about this low reading, and Elecraft told them it should be significantly better than that, and Elecraft is working with ARRL to see why their K3/10 had such a low reading. Elecraft also seems to have made a general recommendation for ALL K3's that until the IMD problem is resolved, the low power amp should be run at no more than 8 watts on 17 meters and higher. ARRL then got ahold of a K3/100 and measured IMD at the output of the low power amp, with that amp running 8 watts, and measured IMD at -27dB. Am I reading that correctly? So for best IMD, until the issue is resolved, the K3 needs to be throttled back on 17 meters and above? Is that like 80 watts or so on a K3/100? Thanks.

I bought 50 feet from Radio Shack. I use a small piece of Plexiglas for the center insulator with a small hole drilled in it. I use a twist-tie to secure it to the ring on the top section of the pole. I have also used a small PVC pipe coupling section from the local hardware store. BLT Tuner (or equivalent set up.

Re: [Elecraft] SMD video?
The SMD technique I've had a lot of success with... my secret ingredient... is... masking tape! Be very careful using any kind of tape around electronics. When you remove it, there is a high likelihood of static electricity build up. Not likely to hurt a resistor or capacitor; could be very damaging to a transistor or IC. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] SMD video? (was: Mystery Mods)
I'm still pretty new to surface mount soldering, but I'm discovering that I really enjoy it! Last night, I was building a tiny little oscillator, just for the SMD soldering practice, and I discovered a spot where I needed a 1K resistor, but didn't have room for a big 1206 resistor... so I found an itty-bitty-flyspec sized one on an old hard drive board, desoldered it, and put it into my circuit... and it worked! I could barely *see* that little resistor without a magnifying glass. I think it was either an 0603 or a 0402. The SMD technique I've had a lot of success with... my secret ingredient... is... masking tape! Put the part on the board, tear or cut off an appropriately sized piece of masking tape (from big to tiny), tape down one side of the part, solder one end (or a couple of pins), remove tape, solder the rest. For the tiny parts, it's easier to cut a little piece of masking tape with a small pair of scissors and position it with tweezers, because the rough edges from tearing the tape make it harder to get a good hold on the edge of the component. I don't know if this is unorthodox or not, but it seems to work well for me. The other tool I use a lot is a pair of bent-nose locking tweezers that I got from Micro-Mark. They're actually to big for any of the really tiny parts, but in a lot of cases I can use them to clamp down a SMD resistor or capacitor. I have a small $20 magnifying lamp, and an illuminated magnifying glass, and a pair of cheap reading glasses from the drugstore. I don't have a fancy visor or anything like that. I still want to get a flux pen and some thinner solder! At the moment I'm still using the same iron, tip, and solder I used to build my K2. It works okay, but a slightly smaller tip, and finer solder, would probably give me neater results. So, Wayne, Eric, can we have an all-surface-mount radio kit that we can solder *ourselves*? :-) Sarah AF6FH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 - Indicated Signal Level
G'day, In the a review of SDR receivers in the March 2008 RadCom (RSGB Magazine) is the following: the indicated signal level does not vary with the attenuator/gain/preselector setting. To achieve this the control program keeps track of the gains and losses in the signal chain and always displays the exact signal level in dBm I would certainly like my K3 to display an S-meter reading independent of ATT or PRE selection. This would go some way to making S-meter reports more meaningful. Currently switching on the attenuator, for example, reduces the other guys setup from a beam and kW amp to 100W and a dipole.

[Elecraft] K3 filter presets I/II: present and future functionality
Do you find the DSP/XFIL filter presets, I/II, useful? If you haven't tried them yet, please do. Here's the short version: In each mode, there are two presets (you can also think of them as configurations). Each preset is just a combination of DSP settings and the corresponding automatic crystal filter selection. They're intended to be set to match the present operating situation. First, set up preset I the way you like it, then switch to preset II and do the same. From then on, you can go back and forth between them. For example, you might want narrow and wide settings in CW mode. Or in SSB mode you might want one setting that's normalized to the 2.7 or 2.8 kHz crystal filter, and another that's shifted down and narrowed somewhat. Our firmware field testers have suggested a different way of using these. Rather than have the presets float (change every time you move the DSP controls), they'd like to see them fixed (so that they don't change unless you specifically modify them via a menu entry, etc.). This change is more significant than it sounds. Instead of having two freely-changing presets (configurations) that you go between, you'd now have just one working configuration. When you hold I/II, you would be loading either of the *saved* preset values into it. It would be similar to recalling a saved frequency memory which gets loaded into a VFO. Both the working configuration and the two saved presets would still be independent for each mode. Before we make any changes, I'd like to know: - if you use presets at all - if you like the new proposal better (making them fixed) This is the beauty of firmware: it's malleable. No need to keep functionality if it gets zero positive feedback. 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.

But two of the 7 are remove SMT resistor package and jumper. I'm guessing a little spot of solder on top of the SMT device would achieve the same purpose without needing to disturb the pads.

Greetings: I use the I/II switch especially when coupled with HRD DM718 in PSK-31 mode. With the switch setting to a previous wide (I) setting, I see the whole waterfall spectrum, pick a signal, click the DM718 centering which autosets the K3 freq to the center of the bandpass, click the I/II which selects the previous 50hz bw setting.

[Elecraft] K3: Filter presets: I and II
I use the presets all the time, just about every time I operate (cw). I like them the way they are, but to be honest, I don't see a whole lot of difference between locking them and adjusting them on the fly. Since everything is possible in firmware, can't you do both? Push the right knob to select 1 vs 2, or- depress BOTH the left and right knobs at the same time (Norm and I/II) to toggle into the fixed bandwidths. Best of both worlds? de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Portable Antennae
I have been extremely happy with the Pacific Antennas PAC-12 mini vertical. It's a kit that's easy to build, very light, breaks down to a very small bundle 12 inches long, and it's been very efficient. I worked VP6DX on 3 bands with it! Price is right as well. Easy enough to buy one just to throw into the car trunk and have for casual or emergency comms. BTW, I am using just the stock, simple 8-foot radials that come with the kit. Takes no time at all to set up. Just push it into reasonably soft ground, spread out the radials in an 8- foot radius, connect a 15-foot piece of RG-174 coax with BNC's on both ends, and start calling. I'd much rather set this antenna up in a random campsite than string a wire antenna. Unless you're camping on concrete, you can always have the antenna feedpoint within a few feet of where you want to be sitting. Very happy customer--I bought two of them, no financial interest other than that. BTW, they have two versions that differ only in the loading coil. With one, you wind individual coils for each band that you swap out (60 seconds max). The second version has a single coil with a tap wire and clip that you move. My first purchase was the one with the individual coils, and that's the one I've been using most of the time. All the parts are identical and interchangeable otherwise.

Re: [Elecraft] K3 filter presets I/II: present and future functionality
Yes, I use the presets, and I agree with the field testers as to the change. I would like to be able to return to fixed settings that I program and are stored. That way I always have a familiar starting point that works best in most situations, but that I can adjust further to customize for the particular signal I'm listening to. With the current setup, I feel I get lost and can't return to a familiar place. While we're at it, in Data mode I can't seem to get to a wide filter setting, which is important to find and initially tune in a station. Data seems to default to a very sharp filter (50 hz) that makes it difficult to tune in a station at the outset. Thanks for asking. Les WB6MND wayne burdick wrote: Do you find the DSP/XFIL filter presets, I/II, useful? If you haven't tried them yet, please do. Here's the short version: In each mode, there are two presets (you can also think of them as configurations). Each preset is just a combination of DSP settings and the corresponding automatic crystal filter selection. They're intended to be set to match the present operating situation. First, set up preset I the way you like it, then switch to preset II and do the same. From then on, you can go back and forth between them. For example, you might want narrow and wide settings in CW mode. Or in SSB mode you might want one setting that's normalized to the 2.7 or 2.8 kHz crystal filter, and another that's shifted down and narrowed somewhat. Our firmware field testers have suggested a different way of using these. Rather than have the presets float (change every time you move the DSP controls), they'd like to see them fixed (so that they don't change unless you specifically modify them via a menu entry, etc.). This change is more significant than it sounds. Instead of having two freely-changing presets (configurations) that you go between, you'd now have just one working configuration. When you hold I/II, you would be loading either of the *saved* preset values into it. It would be similar to recalling a saved frequency memory which gets loaded into a VFO. Both the working configuration and the two saved presets would still be independent for each mode. Before we make any changes, I'd like to know: - if you use presets at all - if you like the new proposal better (making them fixed) This is the beauty of firmware: it's malleable. No need to keep functionality if it gets zero positive feedback. 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.

[Elecraft] ARRL Reports Ducie Operator's K3 Comments
I wonder what they could sell a K3 out for if it was made in China? $1,200? I have no knowledge of manufacturing, but, judging from the fact that everything else is made over there, I wouldn't be surprised. Actually, you might be surprised. Automation makes for a great equalizer. I bet there is not much difference in assembly and parts costs of the boards between on-shore and off-shore. Assembly houses throughout the world use similar automatic equipment, and the parts are all very similar in cost as well. Where your savings occur is in actual labour costs. So I think that the savings could possibly be seen in assembled K3s, as the labor would be cheaper. BUT - there isn't that much labor associated with the K3, due to an outstandingly well thought out design (as anyone who built the K3 knows). And we all know what the assembly labor costs are (not that high). So you'd save on labor, but then you would pay import duties. Bottom line - I bet there would not be that much of a savings.

[Elecraft] Portable Antennae
I operated mobile for many years and here is how I handled the antenna's. When in motion I had a 20M Hamstick on one side of the motor home roof and a 40M Hamstick on the other side of the motor home roof. Each of those Hamsticks was on a quick disconnect fitting. So when we reached the destination for the day, it took just an instant to remove one of the HamSticks and replace it with a long wire. I had two long wires in the RV, one 33ft long and one 66ft long. In the 15 years I was running mobile around the 14 states in the West, most camp sites had at least one camping spot with some sort of object to throw the long wire over. If there was only one low tree or shrub to throw the long wire over, I used the 33ft wire with the tuner. But if the terrain allowed, I used the 66ft long wire with the tuner. Having a full sized vertical 66ft long on 80M was a huge improvement on the lower bands. I usually got the wire up 33ft to 45 ft and then the top was bent over horizontally. Using a nylon cord to pull it to another object till it was tight. I used the vertical long wire because it was stealthy and you can have it in operation very fast. With the least amount of disturbance to the others in the camping area.In the desert locations of the West there was generally some sort of scrub or other type of object to throw the wire over.If the site just didn't allow any type of long wire, I made due with the HamSticks.The large motor home provided the ground plane. All anyone ever saw was a thin wire coming off the top of the motor home to a tree. And you had to look very close to even see it. The first antenna's I tried for mobile use were the top loaded Hustler verticals.I found them to be almost as good as a dummy load. But when I switched to using the higher efficency Hamsticks, I was able to easily work DX while in motion on 20M . I see a lot of hams today use amplifiers in their mobile setups and that's probably because it takes 500W to overcome the losses in the in some of the lame mobile antennas I see on the market today. I think I've seen them advertised as screwdriver ant. Frank W7is **Ideas to please picky eaters. Watch video on AOL Living.

[Elecraft] RTTY and K3
I am reading the book here and trying to understand how to set up RTTY or PSK with the K3. What gets in my way is the RTTY reading and generation algorithm. I am not all that excited about that right now, but I am just trying to get my sound card hooked up to the Input and Output with PTT as well. Three simple cables and I am sure where all that goes. What is confusing is how to set up the radio. AFSK-A is selected by the B Vfo when you use Data MD. So supposedly, the line out audio which goes in the sound card will work, but more importantly, the line in of the K3 will accept the audio generated by the soundcard. I don't have to turn on the TEXT DEC unless I want to see the RTTY message on the K3's screen. Once I get FSK set up and I would them change VFO B to FSK D. I think that is right...or have I taken a wrong turn... Lee 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.

RE: [Elecraft] ARRL Reports Ducie Operator's K3 Comments
I work in a company that does a lot of overseas work and if quality is important you end up in places like Singapore and Malaysia. Then you also end up paying a lot more for labor. Average wage for employees in our Singapore CM is 13 dollars an hour! I GUARANTEE you could get someone to tune things up and do a good job in the US for that rate! You could get some high schooler hams to do it for that wage and they'd love their jobs and take great pride in it. Our biggest problem where I work is that we're idiots. Our system only allows for one price to be put into the system and that price is put into the system when the engineers are buying prototype quantities. So then when we print out a BOM cost its heavily inflated because they are onesy twosey costs. Then when they ship this BOM overseas they are amazed at how much less expensive it is overseas. They think that this is because of the buying power that the contract manufacturers have. But it's only because our costs are so inflated. Not to mention the severe speed decrease that you have to take when changes are needed. As well the fact that many contract manufacturers build a lot more than you ask them to and when you make a change your scrap costs can end up MUCH higher than you planned for. They usually make way more than you ask them to as it helps them cut costs but they rarely pass these savings onto you and have no problems passing the obsolescence cost onto you when it's their actions that increased that cost beyond what you specified. Just the other day I found a place where a contract manufacturer was double charging us for a part and we'd ended up overpaying by about 3/4 of a million dollars over the last couple years. They made no offer of repayment but made up a story about how it was not their fault and how we'd agreed to pay the price we were paying. So I'm not so sure it really makes all that much business sense. Things keep getting more and more expensive over there. Heck as the US dollar keeps going further and further down in value then that only makes it all the more expensive. Not to mention the fact that Wayne and Eric would be in planes constantly going over to the CM to try and flesh out problems then firmware updates would be even lower on the priority list of things to manage. But there would be tons of radios out there which makes them worth less money to the end user this only cuts into the bottom line of the manufacturer though. Feel free to flame away but I've done quite a bit of design with overseas manufactures. I LOVE it when we're making boards domestically for prototypes and HATE getting work done once its gone overseas. The unfortunate thing is that we're so stupid now our operations department is looking into selling our SMT equipment and looking at making us do all of our prototyping overseas. No more 5 day turn fabs! Any and all changes will take several weeks to get anything back and will cost a heck of a lot more. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill W5WVO Sent: Friday, February 29, 2008 4:57 PM To: Dave Andrus; elecraft@mailman.qth.net Subject: Re: [Elecraft] ARRL Reports Ducie Operator's K3 Comments I would be very surprised if outsourcing manufacturing has NOT been thought about and discussed behind closed doors.

Re: [Elecraft] K3 filter presets I/II: present and future functionality
I don't like the presets floating every time I make a change. They are not presets, they are resets and I never know what might result from pushing the button because I can't remember what width was used the last time I switched it. I would much rather have a wide preset and a narrow preset that I can quickly and easily get to. Even better if I get to pick what that might be. I would know that if I hit the preset I in CW mode it will be a narrow 500hz and preset II will be a wide 1.5kHz. In SSB mode I might chose a preset I as narrow 1.6kHz with the passband slewed to increase intelligibility and preset II as wide 2.1khz with the passband centered. The NORM function is nice but it is fixed too narrow (400hz) in CW mode and too wide (2.8kHz) in SSB. Maybe NORM should be used just to center the passband and then the user could set the two presets for the desired widths and passband offset. k4ia Buck K3 #101 Fredericksburg, VA **Ideas to please picky eaters.

[Elecraft] K3 - Another one on order
Well, you guys are obviously having way too much fun, so I caved in. I recently committed $3K for a 3K, and I suspect Ill not see it for some time. I dont own any Elecraft products, nor have I ever built an Elecraft product. Ive never seen one, held one, or heard one to the best of my knowledge. I also make it a habit of never, ever buying a new transceiver until it has been out for a few years. So why would a reasonably sane and economically conservative person such as myself, do something so out of character? For me, its not all about the product. Its about the Elecraft team, and how they run their business. It has to do with the passion they exhibit for what they do, the integrity with which they execute their enterprise, and the collaborative quality of their customers experience. I own transceivers from the big three offshore manufacturers Kenwood, Icom and Yaesu. I like what I have, but I might as well have purchased them from a vending machine. Firmware-upgradeable radios (forget about hardware-upgradeable) are fine in theory, as long as the feedback loop from customer experience results in meaningful and measurable product improvements, implemented in a timely manner to the customers satisfaction. I believe that is what Elecraft is accomplishing. As good as the K3 apparently is now, I am pleased that Elecraft is not completely satisfied with the K3 product development yet. That attitude speaks volumes about my future experience with this radio, and was a significant aspect of my buying decision. As an Elecraft customer outsider, I have watched their growth and performance, and have spent quite some time reading reviews of their products, and I especially pay attention to the postings from this reflector, but I must say it is getting quite tiresome of late. It is easy to get caught up in the issues du jour, but is it always wise or beneficial? I suspect there are those who are just not comfortable in the dynamic, collaborative customer experience that Elecraft has generously and openly fitted into their (proprietary) business planning. What a breath of fresh air these guys are! And finally, I apologize for this one-time, non-technical post. I look here only for that which addresses technical or operability aspects of these products, and as such, will refrain from posting anything that strays from that goal in the future. Im looking forward to jumping back in here when my K3 arrives. In the meantime, those K1/K2 kits are looking pretty good. 73 Looking for last minute shopping deals? Find them fast with Yahoo!

[Elecraft] OT: FO5A/mm Clipperton ship strong on 40m SSB tonight
I don't mean to turn this into the Elecraft DX cluster, but for those that are anticipating the next interesting DXpedition--Clipperton Atoll, that team is in the contest on 40 meter SSB on 7.228 with 100 watts from their ship, enroute to Clipperton. They are using the call FO5A. When they get on shore, they will be TX5C. Here's a chance to work them early! They are also periodically answering questions about who they are and when they will hit Clipperton. Right now, the op says they will be there on March 6th. They just said they are about 940 miles north of Clipperton (this was said at 0515Z, March1 (UTC). Check QRZ.com for TX5C, and the info on the /mm operation will be there, as well as info on their QSL manager!

[Elecraft] RTTY and K3
Hello Lee You are about right: Line in/line out are just alternatives to using the front or rear microphone socket and work on SSB as well as data. Data A (short for data audio) is the same as SSB, except that compression is forced to zero. You can reverse the sideband by pressing and holding ALT. The dual passband isn't available in this mode, neither is text decoding on the K3 screen (trying either results in a display of N/A). Generally used with any sound card data mode. AFSK A is used for audio RTTY but otherwise is the same as Data A, sideband reverse is available, dual passband works and so does text decoding. Sending RTTY via the paddles doesn't work on this mode. FSK D is for hard wired RTTY keying. This mode also allows RTTY keying by using the Morse paddle input. Sideband reverse is available via ALT, dual passband works as does text decoding. I've not tried the PSK D mode. For hard wired RTTY, the single transistor shown in the MMTTY help files works fine. Perhaps the easiest way to operate the K3 on sound card data modes is with Ham Radio Deluxe and DM780 (included with HRD). You only need two audio cables to/from the Line in/Line out and a serial cable. HRD keys the radio via the serial cable (no need to specify anything special, except to set the serial data rate and comm port), the program also knows the RF frequency of the displayed tone, so setting your K3 to the centre frequency of one of the Olivia 500 channels doesn't involve any head scratching or maths on your part! 73 Dave, G4AON K3/100 #80 I am reading the book here and trying to understand how to set up RTTY or PSK with the K3.
