Re: [Elecraft] Re： On the advisability of selling kit radios
Hi Johnny Elecraft could become a killer company if it was very aggressive. Products that I think would be a huge success if Elecraft put their name behind them would be these. A SDR receiver like the SDR-IQ/QSR1/Perseus with better interfacing for ham radio use. Besides hams low band AM band DX'ers are huge in numbers. Their numbers alone would justify Elecraft producing a SDR. A SDR transmitter, Phil Covington and HPSDR are just too small to bring these products to the market in a realistic time frame. The curiosity factor is now not in the 3rd quarter of 2013! Who wants to waste money on experimental products that are not supported by people like TAPR? Not me! A fully direct sampling transceiver like the ADAT from Elecraft would be fantastic. While contestors are an important group for high performance radios, their demand is minuscule compared to the general ham population who just likes playing around. Ultimate receiver specifications dont always factor into most hams purchasing decisions. If you want clues for this look at the Softrock Yahoo group, 6000 members! What other ham radio group has this number of members? All the big players are missing the boat, anyone who takes on this SDR market like now will dominate ham radio manufacturer into the future. Its a momentum that cant be stopped. The K3 is bordering on obsolete probably within 2 years with the fast march of SDR transceiver technology. Products like the Flexradio are great, however they just dont get the point that people dont want to boot a PC for ham radio use. If Flexradio had some kind of embedded front panel for the Flex5000 it would be a huge hit. Variations of the K3 product would be a good start. A K3 with a single receiver and 200 watts. Why not build the P3 into this single receiver K3 with a power supply? It certainly would give most of the Icom lovers something to think about. Why bother with kits? Just mass produce the whole product in Mexico or wherever, it will sell. Why not produce a K3 version of the Orion? The Orion languishes with poor firmware development. Elecraft should strike and recruit the dissatisfied Orion owners. The new Yaesu FT5000 despite its crippled second receiver is going to be a huge seller. While many in here whine endlessly on how bad knobs are, if the market wants knobs and a bigger box give it to them. The business world is littered with the carcasses of businesses who thought that they were right by trying to force feed the market with a product that the market did not like. Technical superiority is not always important. While many people scorn MFJ, MFJ has the right attitude because it identifies new ideas and opportunities and gets them to the market place fast. They are successful because of their ability to bring their products to the market place very fast. I have been burnt by MFJ, however some of their new products like the Intellituners are superbly engineered products that are just as good as Palstars Auto tuner in quality. Just examine MFJ's PCB;'s its not junk Why does not Elecraft produce a tuner like MFJ's 1.5kw Intellituner? With so much interest in balanced feeders/tuners, 43ft verticals and remote tuners on every ham radio forum every second day, I am surprised that non of the big players have woken up to this perceived need. I have seen more cries for a legal limit remote tuner than I have seen for 100 Db IMD dynamic range receivers on ham radio forums. The only problem that I see here on the Elecraft list is that many people want to force feed you a bread and water diet for your ham radio enjoyment. This bread and water diet with the overemphasis on receiver specifications wont win you a big slice of the ham radio market by itself. You really need to fire up peoples imaginations with ideas, new concepts and products. Elecraft could easily occupy the technical moral high ground if it set out to do so with decent products. Another product could be a Autotune HF tube amplifier like the Acom. If solid state is way too hard, tubes would be a good alternative. This amplifier would use a single 8877 or 3CPX800's. With Elecrafts name on this product it would be a huge hit. Who can argue with Acoms success? A kit autotune HF amplifier could also be possible. You could have this kit with and without auto-tune I would be willing to put my money where my mouth is and pay deposits for some of the products that I have mentioned. All I can say is that Elecraft should not be shy. It should email its customer base directly and ask them directly what products they would like. One thing that I will finally say is that Elecraft should stick to producing the best possible products. The ham market is flooded with junk products that dont really perform the way they should. Its heartening to see products like Acom, N8LP Wattmeter, Microham and W5BIG all who produce basically technically perfect products. This

As I recall from my 1960's USAF military electronics days, tests were made comparing FSK versus the then new AFSK.

Re: [Elecraft] Softrock panadapter for K3
Guys, I'm in the process of doing this. I'm no expert. There seems to be no single source tutorial anywhere. One has to be willing to do a lot of GOOGLE searches to overcome problems you encounter along the way. Several of the PVRC guys have these up an running. It isn't as simple as it looks at first blush-- especially if you want frequency displayed on the panadapter. I'm interested in a type of display that doesn't move displayed signals when you tune the K3. That's not what you get ordinarily. Many people experience hum problems with the $19 variety SDR. Solving this involves a lot of experimentation. SDR center frequency feed though is also a problem. The Z1 buffer amp helps keeps this out of the display. Like the PVRC guys, I'm interested in having the panadapter export spots to a logging program. Doing so involves a number of layers of both hardware and software. This requires use of SKIMMER software hooked to the SOFTROCK IF radio. SKIMMER simultaneously decodes the whole band of CW signals. The result is a bandmap of data showing calls and frequencies. These spots can be exported to a telnet site. Other gotcha's: 1) SKIMMER is a big CPU hog. Running it and several other programs at the same time really requires a multicore PC or a very fast single CPU machine. 2) SKIMMER needs K3 frequency info. So you need to use some software to create port sharing so that frequency info is available to both your logging program and SKIMMER. 3) The buffer amp isolation of the SR center frequency signal is a requirement. 4) SKIMMER can export spots to TELNET. However, you will most likely need a program which combines TELNET packet cluster spots from several sources into one TELNET port for your logging program. Because of 1) several guys have gone to running SKIMMER on one machine and the rest of their software on another. Getting the shared port info from the second computer to the first is another obstacle to overcome. I'm sure there are more gotcha's in doing this. I'm not far along to have stumbled upon this just yet. 73 de Brian/K3KO Don Wilhelm wrote: Bill, You will find all the documentation you need on the SoftRock40 Yahoo group. I don't like navigating Yahoo Groups much, but the info is in the Files area, and you have to join the group to get access.

Once more time,I thanks Elecraft team for have been designed and built the radio ranked # 1 in this planet on performance,some of my friends says its the highest performer but they consider it an ugly radio,I keep telling them its in the eyes of the beholder after selling the most beautiful radio in the market that I owned,the FT-2000 it was kinda hard to get used to this new look but now I see it everyday and I say,yes its beautiful radio as any other can be.And as Rick said it will be with me till the end of my life.Its definitively a keeper. 73 For a refined ham it is compulsory to own a k3 __ 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

We are not making up for deficiencies in the K3 design, but are talking about how to best use the tools available for extreme operating circumstances. These suggestions may not be for everyone. Those performance enhancement tools will be used differently depending on the circumstances of band conditions, antenna selection, and operator preferences. Not everyone will want or need to use those tools. Comparing it to driving a high performance vehicle. If you just want to cruise the streets, the normal settings will suffice, but if you want maximum performance on the race track, you will want to use all the tools at your disposal, and customize them for the track being used and the driver's preferences (these may be different for every race). Those who want to just use the standard setting for this race will likely not come in as front-runners, but they certainly can participate. Just how much you want to dance the AGC up and down is a decision each owner must decide for him/herself, no one answer fits all. Use the default settings if you do not want to make any decisions or do not want to do any experimenting (trial runs).

If only one PC is kidnapped, the bad boys know the email adresses there, also if it is not in the adress book.

Re: [Elecraft] DATA Jack for K2??
Jon Perelstein wrote: Is there any chance that Elecraft will develop a data jack add-on kit for the K2? I do a lot of PSK and other digital modes with mine, and it's a pain to use the mic plug and headphone jack as my connection points to the radio (if for no other reason than the fact that I would like to be able to hear things as I tune across the band). I would much rather have a data jack that inputs and outputs digital data like the Yaesu FT-897. If you have the AF filter board installed then there is a take-off point on it that can be used to bring fixed level audio to a socket on the rear panel. Transmit is not such an easy solution. Since you need to attenuate the signal from the computer I suspect you could feed it in parallel with the mic input and connect to a 3.5mm jack socket or other connector dangling off the back of the mic plug. Since I rarely use phone I never bothered to do that as it wasn't much trouble to swap the mic plugs over. Some years ago Pauli EA3BLQ (SK) developed a board that did exactly what you are asking for. I have never understood why Elecraft did not adopt it and put it into production as an official K2 option as they did with the DSP board. I am sure there would be a demand for it even now, after all the K2 is still a current product. Although I don't use my K2 much now I would buy one just to fill that gap in its functionality. - Julian, G4ILO.

Re: [Elecraft] KXV3 RXA board vs KXV3A
Jeff, I am not certain what you are referring to as a KXV3 with the KXV3 RXA board. If you are referring to the RX Antenna, I believe that always has been a part of the KXV3. If there was a different KXV3 RXA version, would someone please inform me. Yes, the KXV3A is required to install the K144XV - the A version has the switching for the K144XV, and the non-A version does not. I would say you need to order the KXV3_UPGR so you can be prepared when your K144XV arrives. 73, Don W3FPR Jeff KB2M wrote: Maybe I'm not awake yet, but I'm trying to figure out what the differences are between a KXV3A, and a KXV3 with the KXV3 RXA board.

Re: [Elecraft] DATA Jack for K2??
There *was* a board available to provide higher level fixed audio out of the K2 - look at the K2 Specific Files on Tom Hammond's website www.n0ss.net - you are looking for the W3FPR Fixed Audio Output information. Tom no longer has boards, but will send you the board image to allow you to make your own. Complete documentation is available to download. With the fixed audio board in place, the rest is easy, but is easiest to do with a switch outside the K2 - to disconnect the microphone to the data input and route the PTT from whatever switching arrangement you use for data modes to the mic connector. If you also route the Fixed Audio output to an unused microphone pin, all signals are available at the microphone jack. For one example of this implementation see the Switchbox for K2 data modes on my website www.w3fpr.com (yes, I probably should update that article - will do when I have the time!) - the principles are there in the article and it includes isolated data input/output, so it serves as the complete data mode interface. 73, Don W3FPR Julian, G4ILO wrote: If you have the AF filter board installed then there is a take-off point on it that can be used to bring fixed level audio to a socket on the rear panel.

Re: [Elecraft] K2 SSB, Hi Cur message on PTT
Thanks, Don--I do have the same symptoms when I connect paddles and hit the dot paddle in SSB mode--I'll try the adjustment you recommended and keep working at it. 73 de aa0ms On Mon, Feb 8, 2010 at 6:08 PM, Don Wilhelm w3...@embarqmail.com wrote: Doug, Start with the easy things first - it could be RF Feedback or some type of oscillation in the mic itself - or it could be a lack of carrier balance on the KSB2 board. To check quickly, do not connect a microphone at all - just connect your paddles to the key jack, and in SSB mode, close the dot paddle (the DOT line inside the K2 is the same as PTT). Do you have any power output? You should not because there is no audio. If you do have RF output, the first step is to adjust the carrier balance pot on the KSB2 board for minimum RF - you may have to compromise between LSB and USB, but the carrier level should drop to a very low level at the correct adjustment point. That point should be near mid-range on the pot, if it is not, then look for a problem. Once you have the carrier balanced, it is time to try the microphone again - since you now know the carrier balance is correct, this time suspect RF Feedback (or audio feedback if you have a computer soundcard also connected) if it happens when the mic is added. There are other possibilities such as a problem in the ALC section of the KSB2 board, but try the above before doing anything else. 73, Don W3FPR Doug Heacock wrote: I dusted off my old K2 recently and decided to try to wire up an electret mic and give SSB a try--I've had the SSB module since I built the K2 years ago, but just never used it, because I had no mic at the time. I've discovered that when I ground the PTT line with the K2 in LSB or USB mode, I get the Hi Cur message, and my output power goes to well over 15W, regardless of the setting of the power output control. I've done some of the voltage checks recommended in the SSB module manual, but only those for RX mode--I'm a little nervous about trying to measure voltages in transmit mode, because I don't know how long the PA can take that kind of current, and I don't want to fritz the final or cause other problems. There are some voltage discrepancies associated with U2--pin 5 on that device is supposed to have 0.6v in RX mode, but I'm seeing more like 2.5v. Pin 3 of U4--same story. If anyone out there has any suggestions for where to look for problems, or how to do further testing, I'm all ears. I found an old thread in the list archives that suggested replacing Q3 and/or Q4 on the K2 control board, in case one of those 2N7000s happened to take a static electricity hit, but I haven't had a chance to do that yet (don't have any 7000s lying around), and I'm somewhat hesitant to go down that path because this rig seems to work just fine in CW mode.

Re: [Elecraft] Softrock panadapter for K3
Bill - I have built and am actively using a Softrock Lite II for K3 IF kit. These kits are not currently being sold by Tony, but the kit is a Softrock Lite II for 40 m with a different crystal and several other small changes in caps and toroid windings. I do have the Instructions for the kit. I believe some hams have bought a custom crystal to adapt the Lite II for 40 m to K3 IF. The kit works best with the Clifton Labs Z1 Buffer Amp. This is available as a kit and is inexpensive. A slightly more expensive, but easier solution is to buy the LP Pan. It comes as a kit $175 or built $225. The kit is a very easy build. The instructions for the LP Pan are excellent. They provide all the detail you need to build the kit, select an appropriate sound card, set up the cabling, obtain and set up the software. If you can read and follow instructions, you can make it work. Power SDR IF played with either of these panadapters provides up to 192 KHz of visual display. It provides a second receiver, even if your K3 doesn't have one. It provides point and click tuning on both VFOs. It provides point and click filter adjustment for both VFOs. It allows you to listen to VFO A in 1 ear and VFO B in the other. Sliders allow you to adjust how you hear VFO A and VFO B. And more. All of this is point and click and fully, bidirectionally interactive with the K3. The visual display adds dramatically to the enjoyment and functionality of the K3. If you want to discuss this further, please contact me off list.

Re: [Elecraft] On the advisability of selling kit radios
JMO, There're only a limited number of improvements you can make to a mouse trap before you start getting diminishing returns. For the task of bouncing HF sigs off the ionosphere, at some point more and more technology on that isn't going to lead to any improvement. It's sort of like high technology being applied to, say, archery equipment. In the end all you need is a stick with a string on it to do the job and there's only so many ways to improve a stick and a string. After that you have to resort to gimmicks to sell the new/improved ones and you're not really getting too much better of a stick and string for the purpose of propelling an arrow. One of the reasons I went with a K2 (still under construction) is its lack of frills for doing what I want to do with it (exchange CW sigs on HF) but still has an RX with a performance level exceeding frankly most of the other rigs on the market. Even so, the K2 is still going to end up being, how shall I put it, pretty luxurious of a rig for what I'm going to do. yet it's considered kind of old technology nowadays, especially with rigs like the K3 to compare to. My other rig currently is a 706MKIIG and it's a high-tech beastie compared to what I grew up on when I was a new ham (Heathkit DX-60B and a pair of SB's when I was in college). As for Elecraft going for it and becoming a big company, tell you the truth that's a sure way to ruin a good company. In my career (software) I've worked for one or two companies that were small when I joined and then became big. I think those were the worst things that ever happened to those places and that's in fact the major reason I don't work for those places anymore. I don't know what Elecraft's financial situation is but I sure hope they can resist the urge to go big. It's a privilege to be able to build a rig of the K2's quality myself (tho it's pushing my soldering, building, toroid-winding skills right up to the limit, but hey). And if everything goes right in future, I hope to build a K3 too. I know you have to keep up with the markets, but I hope at the same time we little guys don't get forgotten about hi hi! 73, LS W5QD -- View this message in context: http://n2.nabble.com/On-the-advisability-of-selling-kit-radios-tp4539424p4541979.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] On the advisability of selling kit radios
Terry, Yes, and as I explained to someone else, I too have been involved in this sort of thing for decades. Only our business was not a packaged product like Pepsi, it was software. As everyone knows, giving away software as a means of generating interest in other revenue producing products is not uncommon. Someone earlier mentioned the need for determining the ROI of a new product as a means of justifying its production and sale. However, that ROI does not need to be on that new product but rather it can be on another product. Let us suppose that Elecraft developed an amplifier that they sold at a break-even price. But, this product could easily be used by many people who DO NOT use or buy other Elecraft products. If the amplifier is a success (not in revenue but rather in popularity and respect) then it is very likely to increase, maybe substantially, the sales of products like the K3, K2, P3, or K3+ as new customers are brought into the fold. Yes, loss leaders are a very important tool in doing business. 73, phil, K7PEH On Feb 9, 2010, at 8:11 AM, Terry Schieler wrote: It's known as a loss leader Phil.

Re: [Elecraft] K2 KUSB PROBLEM
I have had the same problem. It is most annoying to see the K2 picture (ain't she pretty!) on the HRD webpage and not get mine to work with my XP machine over the serial-to-USB converter. After a lot of tests, I have concluded that there is something amiss in the converter and the HRD software. Why? The same converter/k2/cpu combo works fine with Logger32. I've tried 2 different chipset converters with the same results. The most recent is one from IOGear that has a polling light on it which provided this interesting tidbit of info: when using HRD, the polling light does not show a consistent polling rate. There are times when the light flickers more than once in between the 500mS polls. Meanwhile, the frequency display (and subsequent data loaded into the log) varies: sometimes it is 7.042.50 like the rig says, sometimes it is 70 while other times it is just 7042. One other test: on another computer using a REAL RS-232 interface, HRD and my K2 act like a happily married couple. I know this test changes two variables but it is an interesting data point. So, I've stopped trying to figure it out and will be content to use Logger32 instead of HRD until such a time that the shack computer can have a REAL RS-232. Since the computer is a laptop and doesn't have an empty slot available, it's either throw out a completely working computer or wait for it crash. Now, the disc drive has been acting funny, so maybe there is a new shack computer in the future...

Re: [Elecraft] Softrock panadapter for K3
I just finished building and installing a Softrock panadapter for my K2 and it works beautifully - all the info that you need to build the softrock is on the softrock files web page. Info on using it as a panadapter is on Jack Smith's Clifton Laboratories web site... probably much more than you'd every want to know. The Softrock wasn't difficult to build, as long as you have a steady hand, a fine tip soldering iron, and a good magnifier. There are a number of surface mount resistors (all of the same value) and 4 ICs that are surface mount. All other components are through hole. The components that are different for using the Softrock as an panadapter are all through hole components. I don't know if the K3 IF version of Softrock is still available, but since the component differences are all through hole, it would be easy to find the replacement parts that are needed. When I ordered the softrock some time ago, I inadvertently specified the K3 version, not the K2 version. Subsequently WB9YIG sent me the different parts and changes needed for the K2, so I have the list of parts and differences for both the K2 and K3 - I can give you that list if you need it. In connecting the Softrock between my K2 and my computer, I followed Jack Smith's approach to reduce noise by using isolation audio transformers, etc. I also built and installed Jack's Z1 IF buffer amp in my K2. For the K2, I'm using the IF version of SDR Radio, which works along with HRD to interface and control my K2. The SDR Radio IF apparently can control the K3 directly without using HRD. 73, Bob W1SRB __ 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

Did you try 1 stop bit in the COM port settings? I think the K2 manual says 2 stop bits but I have had problems using 2 stop bits that went away when I changed to 1.

[Elecraft] High Isolation Headphones

Yes. I work in pro audio, and have owned two sets Etymotic ER4 in-ear headphones for nearly ten years. I first bought them to use in my live recording work, where I'm mixing a jazz band in the same room with the musicians, and they're often playing pretty loud. The isolation can be quite good, in the 30 dB range that Bill talks about, but it depends on how well they fit your ears. The standard fittings are quite soft, and they happen to fit my ears very well. Every person's ears are different, and some need custom ear molds from an audiologist for the ultimate isolation. As I've gradually slowed down my pro audio work, I've ramped up ham radio and when I got back on the air in 2003, the Etymotics almost immediately found their way into my ham shack. They're quite comfortable, and I can wear them for a long time. The real question is, :how much isolation do you need? When I'm working a SSB contest, I'm very happy with the sound, comfort, and isolation of the CM500 headset, but I haven't used it yet in a multi-multi operation.

Re: [Elecraft] AGC DSP Rain Dance
I assembled my K3 less then a week ago, and I don't see where you have to dance around at all. There are certainly a lot of different settings, and I am sure I will spend quite a bit of time finding the right settings for certain conditions. But that is a good thing. Flexibility is good, and once dialed in, you just operate. The AGC on my Mark-V does operate better then the K3 AGC, at least with the default settings. But then default setting is the key word, as I haven't messed with the K3 settings. From what I read, there may be some changes needed for the K3 AGC algorithms, but unlike some rigs, those changes will amount to a firmware download. For weak signal CW, I have found that AGC isn't so good anyway, and turning it off on the K3 works magic. All you need to do is adjust the RF gain, and the results are well worth a small effort. So simple a caveman can do it. Personally, I want all the adjustment I can get. The Mark-V is a good radio, and I still prefer it for SSB over the K3. But, I have found that the K3 Noise Blanker is a bit better then the Mark-V with some QRN, so it will get some use on SSB for sure. On CW and digital, the K3 just blows the Mark-V out of the water, and every other rig I have ever used. Maybe the K3 isn't for those that don't want to learn how to actually operate a receiver properly. For those that do know how to use the controls, the K3 is a masterpiece in functionality. The ergonomics aren't like a full sized rig, so it takes some added effort to learn the controls, but in less then a week, I find it easy to do what I want, and while not as convenient as the Mark-V, when the conditions are tough, the K3 performs. Maybe the FT-5000 will have the best compromise in easy function and great performance, but I don't need another giant brick that I can't take portable, and I sure wont play that much money for a rig. If it's a dance, it's a dance in heaven. :) 73, Bob It would appear that some K-3 owners really enjoy dancing around wasting time and energy dancing the AGC up and down ... and forever fooling with DSP adjustments... -- View this message in context: http://n2.nabble.com/AGC-DSP-Rain-Dance-tp4538336p4542677.html Sent from the [K3] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] DATA Jack for K2??
Jon, Yes, it is audio, so the only problems with breadboarding is the possibilities of inadvertent ground loops and/or RF pickup by the circuit(s). Remember that mic levels are quite low, and that level is what you will be driving the K2 with. So the answer depends on just how rough *your* 'breadboard' circuit is. I would recommend putting the fixed audio output board in the K2 - the raw K2 audio is low level and balanced, and you need a source of single ended audio output. While one of the microHAM cable implementations draws audio from one side of this balanced signal, the level is lower than ideal. All the rest can be done outside the K2 in a small box. How small really depends on the size of the transformers you use in the audio lines - you can salvage small transformers from defunct computer modem boards, they work well. Alternately, you can follow Jim Brown's recommendations to bond the computer and radio together and perhaps eliminate the transformers. 73, Don W3FPR jperelst wrote: Thank you all for your replies.

Re: [Elecraft] On the advisability of selling kit radios
Certainly there is no good reason to start a company selling a 100 Watt kit SSB/CW rigOTOH Elecraft bet it could and it would appear that they are successful. There are some flaws in the logic. The K2 wasn't just another 100W HF and it still isn't today. A base K2 was and is a CW QRP rig with a top-end receiver and very low current draw. There was nothing competing with it then, and there isn't anything competing with it now. If you want a QRP rig with a top-end receiver and the lowest current consumption possible, then even the K3 doesn't complete as it draws 4 times the current on receive. the K1 and KX1 don't have the top-end receiver, but current consumption is a fraction of the K2. I love my K1, and the receiver is plenty good enough for the wire in a tree. With the internal batteries and tuner, I don't need to carry more then a paddle and wire to operate for a long time. Yes, you can add all the options to a K2, and have a excellent 100W rig, but if it had been introduced as an all options only 100w kit, it would have been expensive, and I don't know if Elecraft would be around today. Elecraft started out making a rig that was like nothing else available. There was a big void to fill. Amplifiers are a different story. Where is the void? If you have the money, there are amps that do the job automatically, without any user input needed, other then the ON/OFF switch. As for a loss leader, high power SS amps are great, but those transistors aren't rugged like tubes, and oscillation problems and other issues blowing very expensive transistors could become a big drain on Elecraft's profits. With the design issues and expense, and after the sale expense, I think Elecraft would be wise to stay out of the amp business. It would be a big risk. -- View this message in context: http://n2.nabble.com/On-the-advisability-of-selling-kit-radios-tp4539424p4543194.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Thanks Don. As always, you are a treasure. Jon KB1QBZ _ From: Don Wilhelm-4 [via Elecraft] [mailto:ml-node+4543143-219819...@n2.nabble.com] Sent: Tuesday, February 09, 2010 1:56 PM To: jperelst Subject: Re: DATA Jack for K2?? Jon, Yes, it is audio, so the only problems with breadboarding is the possibilities of inadvertent ground loops and/or RF pickup by the circuit(s). Remember that mic levels are quite low, and that level is what you will be driving the K2 with. So the answer depends on just how rough *your* 'breadboard' circuit is. I would recommend putting the fixed audio output board in the K2 - the raw K2 audio is low level and balanced, and you need a source of single ended audio output. While one of the microHAM cable implementations draws audio from one side of this balanced signal, the level is lower than ideal. All the rest can be done outside the K2 in a small box. How small really depends on the size of the transformers you use in the audio lines - you can salvage small transformers from defunct computer modem boards, they work well. Alternately, you can follow Jim Brown's recommendations to bond the computer and radio together and perhaps eliminate the transformers. 73, Don W3FPR jperelst wrote: Thank you all for your replies.

[Elecraft] Amplifiers, Kits, etc. - 2 cents
I don't have much of an idea of what Elecraft's thinking is on high power other than the available history. From postings here it would seem there is some variance in what users might want or accept in an amplifier. It is hard for me to discern what proportion of the community those who post may represent. Nor can I guess the desires of those who choose not to post. Surely there are many who want and can afford 'it all.' And no doubt many who would be quite pleased with less. Maybe Elecraft knows its base well enough that the following need not be considered. Perhaps Elecraft could survey their customer base by emailing them with a link to a web-based check-off (secure?) form. To get my serious attention an amplifier must have... Watts Output Internal Tuner Auto-Band switching Feature... Feature... Capability... Capability... Specification... Specification... I would consider the following if offered as modular/other options... Internal Tuner Desktop External Tuner Remote Automatic Tuner Antenna Outputs Computer Interface etc... So on and so forth... ... ... The following are not important to me in an amplifier ... ... ?Pricing Information? Mid-power base model @ $ Full-power base model @ $ Everything @ $ A kit should save me $___ over an assembled unit A similar form might apply to other development projects or general planning for Elecraft. Just as well, Elecraft may know the market and their own capability. It could also be that development of an amp or amps could be at a point beyond the need for such information. Myself, I could be interested in a basic mid-power SS amp and definitely with auto-band switching (option?). Small package(s), matching enclosures(s) are appealing. Add-ons could be a consideration...W2-like option added into basic amp, added automatic tuner...for examples. 73, Dick - KA5KKT PS I hope this posting doesn't look like a mess as you receive it. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] Man Hospitalized
MAN HOSPITALIZED WITH ANXIETY OVER HAM RADIO Southland County Morning News Southland -- A ham radio enthusiast was admitted to County Hospital today suffering from anxiety over what he perceived as serious problems with his new radio, authorities reported Tuesday. Irv Stumpo, 55, of East Pharsalia, checked into the emergency room in distress, according to the nurse on watch just before midnight Tuesday. He was perspiring profusely and moaning over and over, 'My K-3 is no good, no good', said Paula Stevens, a nurse at County. He had enormous headphones clamped tightly on his head which we had a ton of difficulty removing, and he was also wearing ear buds, she said. Isn't that strange? He was half incoherent but kept mumbling something about dynamic range and audio artifacts. I have no idea what that means. Randy LaHood, a fifteen year emergency room veteran, said that during an examination Mr. Stumpo went into considerable technical detail about a radio he had recently purchased from Elecraft, a company that makes high-end ham radios. He began by explaining that his radio had 'noisy receiver' and 'mushy signals', explained Dr. LaHood. From what I could gather, he had just spent a lot of money on a radio and hadn't actually noticed any of these problems himself, but others in a internet group kept putting the ideas into his head, he said. Over a course of weeks, Stumpo became distraught over various imperfections in what Dr. LaHood said was a classic case of the power of suggestion. The hospital records also said that Stumpo drew mathematical figures he labeled AGC slope, and filled four pages by writing AGC off, Ear Isolation and K3 repeatedly. Hospital officials could not explain the cryptic scribblings. Dr. LaHood said that Stumpo repeated the phrase mushy AGC for at least four hours while he waited for treatment. Other patients who were in the waiting room at the time moved to the other side of the room for fear he might endanger them. J. B. Archer was one of those in the waiting room at the time who had brought in his twelve-year-old son with a basketball injury. Good ol' boy was pretty upset, I just told him it would be alright, but he wouldn't let up with 'I can't pick out the pileups'. I thought he had been involved in a big accident on the highway. Then he said other things like 'the impedance of my headphones' and 'ride the R. F. gain'. Then he started with 'diversity problem' and I thought maybe he was having trouble with racial relations. He was in terrible shape, I'll tell you that. Rick Culver, president of a local ham radio club, told the Morning News in a telephone interview, A lot of these guys spend five or ten thousand dollars on a radio they think is going to be absolutely perfect in every conceiveable way. When it's not, they go into a panic buying lots of other accessories which promise to fix the issue they think they're having. This is followed by a deep buyer's remorse. He went on to recount a recent case which epitomized this effect. We had one guy who had a radio that put out 95 watts instead of 100. He went berserk and ended up smashing his radio with a baseball bat. Not everyone gets that violent, but he never would have worried about it if it hadn't been for an internet forum that drummed it into his head twenty four seven that his radio was broken.

Re: [Elecraft] On the advisability of selling kit radios
Spoken like a true sales guy. In some businesses (including the one I managed for several years before I retired), that is indeed a viable business strategy. But it's a brainless strategy to use indiscriminately, and lots of companies have sunk their ship by not understanding how and when to use it. How many additional K3's do you think Elecraft would sell (pull-through) because they marketed a high power amplifier? How much additional profit margin do you think Elecraft would make on their other products (overhead dilution and vendor leverage)) because they marketed a power amplifier? How much do you think Elecraft would learn that could be applied toward building even better transceivers because they were building a high power amplifier? Next to nothing in all cases, in my opinion. And, maybe most importantly ... how much sense does it make for your most costly (by far) product to be your loss leader? As I said before, if Elecraft can develop and sell a high power amplifier for a reasonable profit, that's great. Otherwise, I hope they don't try because I'd sure like to see them still be here a few years from now.

Toyota of course has been in the news lately with the massive recalls. It was reported that the Toyota Prius Hybrid is subsidized by about $2500 to $3000 by Toyota. That is, the Prius whole sale price to the dealers is a few thousand dollars less then it costs to build. Every Prius car sold is a money loser for Toyota! Toyota is happy with this though (they said so) because it is their front-line product. It is the product that gives them name recognition, the product that brings them Kudos for high-tech achievements, and the product that brings customers through their doors. Thus, a company does not need to make money on a given product to justify its production and sale -- there are other reasons to build products. A smart company will choose the profit margin for each product individually. It is rare for all products to be treated the same. Some will bring in a margin of 40%, others only 5%, and then maybe others, by plan, minus 10%. The Elecraft K3 may have a 30 % margin and maybe the K2, being in production for so long is now about 50 % margin. But, a new solid-state amp may only be 5% or 7% -- enough to make their customers happy without losing money but not earning money like a K3 or a K2 either. phil, K7PEH __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

After a lot of tests, I have concluded that there is something amiss in the converter and the HRD software. Why? The same converter/k2/cpu combo works fine with Logger32. I've tried 2 different chipset converters with the same results. The most recent is one from IOGear that has a polling light on it which provided this interesting tidbit of info: when using HRD, the polling light does not show a consistent polling rate. There are times when the light flickers more than once in between the 500mS polls. Meanwhile, the frequency display (and subsequent data loaded into the log) varies: sometimes it is 7.042.50 like the rig says, sometimes it is 70 while other times it is just 7042. One other test: on another computer using a REAL RS-232 interface, HRD and my K2 act like a happily married couple. I know this test changes two variables but it is an interesting data point. So, I've stopped trying to figure it out and will be content to use Logger32 instead of HRD until such a time that the shack computer can have a REAL RS-232. Since the computer is a laptop and doesn't have an empty slot available, it's either throw out a completely working computer or wait for it crash.

Re: [Elecraft] On the advisability of selling kit radios
How many additional K3's do you think Elecraft would sell (pull-through) because they marketed a high power amplifier? And how many less would they sell, if there were major problems with some very expensive amps, causing a lot of negative talk? We all know Elecraft has some fine engineers. At the same time, high power solid state amps aren't exactly child's play to design with high reliablilty. Add some users that do stupid things and connect horrific loads to an amp, and it better have some serious design attributes to prevent frying very expensive transistors. Considering the high cost of the components that would fail, and the high cost of shipping a heavy amp to and from Elecraft, it could become a very bad and costly situation, very quickly. Reputation shot to hell, and money down the drain. Icom, Yaesu, and Kenwood all have waded in the amp market, but I bet there are a lot more Alpha amps out there then all of their amps combined. And to be realistic, those of us that have Elecraft gear would look at an Elecraft amp differently then the masses. Everyone else would look at Alpha and some others as tried and true, and Elecraft as that company that make those cool little radios, and question how these new amps will hold up long term. It would take years of great performance to get a great reputation out in the general ham population. But only a few months of problems to get a poor reputation. People love to complain. Very risky stuff, when things are going so well with the current products. :) -- View this message in context: http://n2.nabble.com/On-the-advisability-of-selling-kit-radios-tp4539424p4545694.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Irv Stumpo, 55, of East Pharsalia, checked into the emergency room in distress, according to the nurse on watch just before midnight Tuesday. He was perspiring profusely and moaning over and over, 'My K-3 is no good, no good', said Paula Stevens, a nurse at County. He had enormous headphones clamped tightly on his head which we had a ton of difficulty removing, and he was also wearing ear buds, she said. Isn't that strange? He was half incoherent but kept mumbling something about dynamic range and audio artifacts. I have no idea what that means. Randy LaHood, a fifteen year emergency room veteran, said that during an examination Mr. Stumpo went into considerable technical detail about a radio he had recently purchased from Elecraft, a company that makes high-end ham radios. He began by explaining that his radio had 'noisy receiver' and 'mushy signals', explained Dr. LaHood. From what I could gather, he had just spent a lot of money on a radio and hadn't actually noticed any of these problems himself, but others in a internet group kept putting the ideas into his head, he said. Over a course of weeks, Stumpo became distraught over various imperfections in what Dr. LaHood said was a classic case of the power of suggestion. The hospital records also said that Stumpo drew mathematical figures he labeled AGC slope, and filled four pages by writing AGC off, Ear Isolation and K3 repeatedly. Hospital officials could not explain the cryptic scribblings. Dr. LaHood said that Stumpo repeated the phrase mushy AGC for at least four hours while he waited for treatment. Other patients who were in the waiting room at the time moved to the other side of the room for fear he might endanger them. J. B. Archer was one of those in the waiting room at the time who had brought in his twelve-year-old son with a basketball injury. Good ol' boy was pretty upset, I just told him it would be alright, but he wouldn't let up with 'I can't pick out the pileups'. I thought he had been involved in a big accident on the highway. Then he said other things like 'the impedance of my headphones' and 'ride the R. F. gain'. Then he started with 'diversity problem' and I thought maybe he was having trouble with racial relations. He was in terrible shape, I'll tell you that. Rick Culver, president of a local ham radio club, told the Morning News in a telephone interview, A lot of these guys spend five or ten thousand dollars on a radio they think is going to be absolutely perfect in every conceiveable way. When it's not, they go into a panic buying lots of other accessories which promise to fix the issue they think they're having. This is followed by a deep buyer's remorse. He went on to recount a recent case which epitomized this effect. We had one guy who had a radio that put out 95 watts instead of 100. He went berserk and ended up smashing his radio with a baseball bat. Not everyone gets that violent, but he never would have worried about it if it hadn't been for an internet forum that drummed it into his head twenty four seven that his radio was broken. Hospital officials said that Stumpo was treated with sedatives and is being kept for observation. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 compatible Pan adaptors
Many do it with an SDR like the softrock, but it isn't plug and play. I beleive the method with the lowest effort is the LP-Pan. But the kit is $175 and assembled is $225. For software, there is a special version of PowerSDR, PowerSDR-IF. I do know that the LP-Pan gives you the ability for a second receiver, but that is limited to the same band and within the bandwidth of the soundcard you use. Not like a real K3 sub receiver, but a nice addition even with the limitations. I was lucky enough to find an LP-Pan on EBay for $135 with free shipping. It should arrive on the big brown truck tomorrow, and I am making cables this evening. I already have an external PreSonus Firebox sound interface, that seems to work with LP-Pan, so I may be in business pretty quick. It is only 96kHz/24bit, but that will do for now, until I find a deal on a 196kHz card.

Re: [Elecraft] On the advisability of selling kit radios
Nicely stated Dave. Just because loss leader works in retail does not make it a cure all. Elecraft is not retail by our mainstream standards. It is sort of retail, but more likely a niche vendor. It cannot be compared to Pepsi, Doritos or any other main stream retail products. That was not my intent. My point was simply that the poster's comment that a loss leader could work was worth a comment. But, that's Wayne's and Eric's call. My business is also a niche business, but becoming more retail every day. I have seen evidence of others in my field using loss leaders to promote their business. One guy went nuts and won a huge bid on a loss leader price. Then he had to provide the goods for that price and his business tanked. The BOTTOM LINE lies in THE REAL bottom line. I think Eric and Wayne have done their homework on their product research introductions in the past and we all enjoy the results of their toils. I hope they continue to play off their success. And, I wish them (and US) much success in the future. 73, Terry, W0FM K3 #474 -Original Message- From: Dave - AB7E [mailto:xda...@cis-broadband.com] Sent: Tuesday, February 09, 2010 7:43 PM To: terry.schie...@wirelessusa.com; k7...@comcast.net; y...@bronze.lcs.mit.edu; elecraft@mailman.qth.net Subject: Re: [Elecraft] On the advisability of selling kit radios Spoken like a true sales guy. In some businesses (including the one I managed for several years before I retired), that is indeed a viable business strategy. But it's a brainless strategy to use indiscriminately, and lots of companies have sunk their ship by not understanding how and when to use it. How many additional K3's do you think Elecraft would sell (pull-through) because they marketed a high power amplifier? How much additional profit margin do you think Elecraft would make on their other products (overhead dilution and vendor leverage)) because they marketed a power amplifier? How much do you think Elecraft would learn that could be applied toward building even better transceivers because they were building a high power amplifier? Next to nothing in all cases, in my opinion. And, maybe most importantly ... how much sense does it make for your most costly (by far) product to be your loss leader? As I said before, if Elecraft can develop and sell a high power amplifier for a reasonable profit, that's great. Otherwise, I hope they don't try because I'd sure like to see them still be here a few years from now.

Toyota of course has been in the news lately with the massive recalls. It was reported that the Toyota Prius Hybrid is subsidized by about $2500 to $3000 by Toyota. That is, the Prius whole sale price to the dealers is a few thousand dollars less then it costs to build. Every Prius car sold is a money loser for Toyota! Toyota is happy with this though (they said so) because it is their front-line product. It is the product that gives them name recognition, the product that brings them Kudos for high-tech achievements, and the product that brings customers through their doors. Thus, a company does not need to make money on a given product to justify its production and sale -- there are other reasons to build products. A smart company will choose the profit margin for each product individually. It is rare for all products to be treated the same. Some will bring in a margin of 40%, others only 5%, and then maybe others, by plan, minus 10%. The Elecraft K3 may have a 30 % margin and maybe the K2, being in production for so long is now about 50 % margin. But, a new solid-state amp may only be 5% or 7% -- enough to make their customers happy without losing money but not earning money like a K3 or a K2 either. phil, K7PEH __ 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

Re: [Elecraft] K3 DSP AGC Question
It may be a dance, but hopefully careful intelligent musing over the matter is convincing people that they should get the ambient well down in the analog-to-digital converter (ADC) operating range. If they do, a -99 threshold is a -109 threshold, and further backing off RF gain can make it a -119 or -129 threshold as far as the ADC is concerned, and headroom is being used for what headroom should be used for. Perhaps one should get the ambient well down in the ADC operating range but killing gain (adding loss) before the first mixer and the roofing filter is not the way to do it. If you want to better align the dynamic range of the receiver (or specifically the ADC) to conditions, the attenuation should come in the IF - preferably divided between the first IF and 2nd IF. However, there would still be no apparent reason that the K3 should not be capable of sustaining an AGC threshold at least 10 db higher than currently set with AGC THR = 008 whether that be reached with preamp on, preamp off or attenuator on. 73, ...

Re: [Elecraft] K3 DSP AGC Question
Joe, Can you elaborate your reasons for this suggestion. I had come to believe that the best situation is to place attenuation before the first mixer to give the greatest amount of dynamic range (headroom). Yes, I agree that the AGC Threshold could be raised in the K3 and would be beneficial. I have felt the default of 005 was too low. 73, Don W3FPR Joe Subich, W4TV wrote: Perhaps one should get the ambient well down in the ADC operating range but killing gain (adding loss) before the first mixer and the roofing filter is not the way to do it.

Re: [Elecraft] K3 compatible Pan adaptors
Not being facetious, but you can take the IF output from the K3 and feed it to the antenna of an IC756P3 or IC7600, etc. Just tune the Icom to the IF freq of the K3. An expensive panadapter - yes. Just make sure the Icom never transmits or the K3 will be history. I guess this has been done with K2, etc. I have an IC7600 but have never tried it yet. I also have the LP-Pan. But if I want SDR, I'll just use my Flex3000. As you can see, I am an equal opportunity ham - Yaesu, ICOM, Elecraft, and Flex, not to forget Kenwood. I still favor the K3 above the others.

Re: [Elecraft] K3 DSP AGC Question
I also think that the current max AGC threshold is too low, but I have another question. Why is it necessary for the K3 AGC to have such a sharp elbow at the point where the AGC kicks in? The Clifton Labs plots show such a sharp bend that it seems multi-signal in-band intermod is inevitable, especially with higher SLP settings. Wouldn't it be feasible, and more desirable, to have some more gradual inflection point? I would think that something like a parabolic shape would be better, and the DSP AGC is just the implementation of an algorithm, correct? I suppose that would tend to blur the distinction between different THR settings, but so what? Maybe somebody can educate me ... 73, Dave AB7E --Original Mail-- From: Don Wilhelm w3...@embarqmail.com To: Joe Subich, W4TV li...@subich.com, elecraft@mailman.qth.net Sent: Wed, 10 Feb 2010 01:06:09 -0500 Subject: Re: [Elecraft] K3 DSP AGC Question Joe, Can you elaborate your reasons for this suggestion.

Re: [Elecraft] K3 compatible Pan adaptors
I kept my old 756Pro when I upgraded to a K3, and I've done exactly that. It works, of course, but there is no comparison in performance to what you would get from an LP-Pan or even a Softrock. The 756Pro spectrum display is interesting to look at, but the resolution is really poor for anything useful. 73, Dave AB7E --Original Mail-- From: John Gaynard jgayn...@columbus.rr.com To: elecraft@mailman.qth.net Sent: Wed, 10 Feb 2010 01:34:33 -0500 Subject: Re: [Elecraft] K3 compatible Pan adaptors Not being facetious, but you can take the IF output from the K3 and feed it to the antenna of an IC756P3 or IC7600, etc. Just tune the Icom to the IF freq of the K3.
