[Elecraft] K2 working on 40M
Hi all, In case anyone's interested, I got through with test and alignment II on my K2 last night. Everything seemed to proceed normally. Again, I didn't seem to run into any trouble. My first kit and all I'm expecting to have busted something but so far all OK (even the install of L33 hi hi). Maybe I'll mess something up putting in the transmitter and the rest of the RX in the next build phase, who knows hi. I do need to redo the filter calibration tho, as I didn't get them setup the way I want or record any values. And I'm definitely going to have to add the noise blanker if I have any hope of using the rig at home. The line noise is unbelievable here hi! So that'll be my first project after finishing the rig itself I guess On to build phase III LS -- View this message in context: http://n2.nabble.com/K2-working-on-40M-tp4554916p4554916.html Sent from the [K2] 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] K3 DSP AGC Question
In terms of what an operator can really do with the controls on a stock K3 (as opposed to a theoretical modified K3), would you be recommending leaving PRE set all the time, and only using the RF (IF) gain to keep ambient noise appropriately to the low end of the SA612/ADC ranges? I have not considered keeping PRE on all the time though I seem to need it above 14 MHz due to my poor antennas. I do not know the range of the ADC but find it extremely odd that the (relatively sharp) ACG threshold would be less than 50 dB above the noise floor (-138 dBm MDS). 73, ...

There's currently nothing variable after the SA612. Doesn't reducing the RF (really IF) gain first do fairly much the same thing? Reducing level at Q1 output by reducing at RF gain knob is just barely in front of the SA 612 second mixer and lowers input to ADC at the same time.

Adding attenuation before the first active stage (amplifier) always reduces noise figure because that's where the S/N ratio is determined provided the first stage has enough gain to override the noise of the next stage. 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). That assumes any IMD is produced only in the first mixer. In the K3, the limiting factor is almost certainly later in the chain because of the very good IMD performance of the KR (first) mixer. Without specific analysis, the weakest link is probably the ADC followed by the second mixer. If it was the first mixer, narrowing the roofing filter would not improve the dynamic range. That's why I would do two stages of gain reduction - 10 dB in the 30 kHz IF followed by 6 dB in the 8.125 MHz IF, if needed. A designer always wants to make sure any amplifier gain is sufficient for the noise figure of the succeeding stage but low enough to avoid overload down the line. 73, ...

Re: [Elecraft] Elecraft Amps
I would give up my Icom PW-1 for an Elecraft solid-state amp. Oh, wait a minute. No, I won't give it up as long as I still have my Icom 756 Pro III but I would very much buy the Elecraft amp given that it is a 1 KW solution at least and the price is not too bad. Well, I might even consider a less then 1 KW amp. A watt may be a watt on the receiving end but they are not always the same on the sending end. And, with regard to amp ownership and usefulness, I am always on the sending end, never on the receiving end. So, what features would an Elecraft amp add that you can't get elsewhere: 1.

Re: [Elecraft] Elecraft Amps
I wonder what true compatibility is. An amplifier either works well with the K3 or it does not. I know that both Acom 1000 and Acom 2000A work perfectly with the K3. Interfacing an amplifier is not such a big deal with the K3. Of course some of our fellows have questions from time to time but I believe that most people get their amplifier to work just fine with the K3. I should love to see Elecraft with successful amplifiers which were making good money for them. I would be very sorry to see them bring out such a major product which did not return its investment. Maybe Elecraft will show us all again that they can beat all the competition but amplifiers are a bit more basic. An old Heathkit SB200/220 can still do wonders to raise the output a few dB. 73 Doug EI2CN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of lawrence libsch Sent: 11 February 2010 15:49 To: elecraft@mailman.qth.net Subject: [Elecraft] Elecraft Amps Group - For those who believe Elecraft can't compete in the amp market, I ask you to consider the market into which Elecraft introduced the K3.

Bambershoot initially came to headquarters reporting he had been victimized buying a radio from a mysterious Californian named Ellie Craft. Ms Craft allegedly took advantage of Bambershoot by claiming to have down-conversion which he mistook for a syndrome of the same name. Bambershoot was happy with his purchase until his friends told him how foolish he had been. According to Police spokesman, Ken Wood, The poor man was distraught and raving about roofing filters. What the heck are they? The arrest report filed by fellow-ham and officer, Ike Com, listed Bambershoot's original complaint as radio mushiness but notes, I told him all my radios sound mushy but he was upset he couldn't hear it on his. When we tried to calm him down he became unruly. Su Yae, an EMT called to the scene, defended Bambershoot saying, When I got there he was on the floor repeating 'A, G, C, Slope, Pre and A T T' over and over. He was babbling. They claimed he was clicking his heels but I didn't hear anything. The poor man was just frustrated because his purchase had so many faults he couldn't find. I feel sorry for him.

Eastern Standard Time, alor...@sbcglobal.net writes: 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,

Re: [Elecraft] Elecraft Amps
I would also vote for a soldering style kit but I also recognize that there could be some SMT components already in place. Indeed, there are kits like this already where many of the components are SMT on the PCB but there is still work to be done with other components and a soldering iron. I like the idea of a full soldering solution for the PA board though as that would provide the kit interest and motivation with enough challenge adding new skills to deal with high-current RF transistors, cooling issues, and possibly winding your own splitters and combiners (if they are needed). I disagree somewhat with the If I were CEO... comment. That logic may be true for a big company but small aggressive companies win more often by taking the less conservative road and springing out with new ideas. Isn't that where Elecraft came from in the first place. Adding to that idea, back in 1978, several of us engineers mathematicians and programmers had an idea for a new somewhat aggressive business venture so we proposed this to the CEO and other executives of our company. They turned us down. So, we split and formed our own company and within 5 years we had totally surpassed our former company beating them out on more and more competitive bids (large custom projects) in the north american market. Our former company chose to get out of the market that they could no longer effectively compete and they sold that division to someone else. 73, phil, K7PEH On Feb 11, 2010, at 10:15 AM, WW2PT wrote: I'll weigh in, just in case the Aptos crew is taking notes and counting votes. ;-) An off-the-shelf, high-end appliance to compete with THP or SPE would be a high-cost, low-volume, low-profit venture, something I would not want to undertake in the current economic conditions if I were CEO of a small company like Elecraft.

Re: [Elecraft] Elecraft Amps
I wouldn't give up my old SB-200, but I would MOST CERTAINLY buy an Elecraft amplifier should they choose to continue down the path to production. I think they only need to build one amp at this time though, say in the 800 to 1000 watt range. And I don't think it needs to be 100% duty cycle, but certainly something that would support digital modes for several minutes (8 to 10)at half power, or maybe full power. An 8 minute transmit time on digital is a long transmission. I'm no amp expert for sure, but this would seem like an adequate duty cycle. I don't think they need to design another Alpha amp that some of us can't afford. I was going to be quite happy with the KPA-800 for around 3500 bucks (I believe), and it was all automatic with a tuner. As someone stated, making it a modular kit like the K3 is a very good idea. That way you can buy the basic amp and then add accessories as you can afford them (automatic rig following, tuner, built in wattmeter, etc.).

Re: [Elecraft] Elecraft Amps
Since we're dreaming, how about a base model kit (500W) with the option to add up to two additional 500W PA modules via a power combiner circuit. This would allow people to configure it to their needs and/or budget and it would meet Phil's something new requirement. Optional: auto-tuner, optional interface (remote band switching, antenna management, SO2R operation, RS232 control, etc.). Offer a fully assembled version for those with Instant Gratification Syndrome, and everyone's happy! An added benefit would be fault tolerance; the amp could continue to operate at reduced power in the event of failure of an individual PA module -- just pop out the damaged module and repair/replace it. de WW2PT __ 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] Elecraft Amps
Doesn't have to be legal limit. Seems everyone is expressing something in the less than 1000 watt category.

Re: [Elecraft] Elecraft Amps
As someone pointed out, there is less differentiation potential among amplifiers than there is among transceivers. MFJ recently had an ad for a solid-state, all-band, amplifier that was not yet type approved. I haven't seen much since that first ad. It looked pretty compact and was described as capable of reading band-data input and switching bands automatically. It was also described as having discrete power modules instead of a block so that you could replace the bad one and not have to replace 'em all. Now, that said, MFJ doesn't exactly have a sterling reputation for quality and reliability. But, I think they have the right idea, here. My new K3 seems to be working just fine with both the 87A and Centurion, so I have no beef. If there was an auto-bandswitching, all-solid-state amp that took up less space, I'd be interested.

Some of us don't have the time, tools, and/or smarts to homebrew such a creature on our own and would jump all over a kit like this.

Re: [Elecraft] Elecraft Amps
How about 2 K3-sized enclosures...one amplifier, one power supply...both modular. 3 x 500 sounds nice or perhaps 2 x 800...similar with the PS. For the more technically savvy, can 1500 watts be made to work, sans power supply, in a K3-sized enclosure? How about add-ons...particularly a tuner? Maybe a 1500 watt auto-matching tuner would require another K3-sized enclosure. Gee...for that matter, can an auto-tuner be modular and expanded? If 500 watts and PS could fit in one K3 enclosure, could the PS later be moved to a separate enclosure and both boxes doubled or tripled in capacity? 73, Dick - KA5KKT - A Camel pack would look better if it featured a horse. Since we're dreaming, how about a base model kit (500W) with the option to add up to two additional 500W PA modules via a power combiner circuit. This would allow people to configure it to their needs and/or budget and it would meet Phil's something new requirement. Optional: auto-tuner, optional interface (remote band switching, antenna management, SO2R operation, RS232 control, etc.). Offer a fully assembled version for those with Instant Gratification Syndrome, and everyone's happy! An added benefit would be fault tolerance; the amp could continue to operate at reduced power in the event of failure of an individual PA module -- just pop out the damaged module and repair/replace it. de WW2PT __ 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] Elecraft Amps
As I recall Eric stating when they first were developing the KPA800/1500 kits that some portions (high voltage boards) would be pre-assembled for product liability/safety considerations. There probably are a few KPA800/1500 beta amps existing somewhere since I believe they were doing some early field testing back in 2006 or so. In 2005, Eric had a working prototype of the KPA800 in his room at the Holiday Inn (QRP hotel - kind of ironic). I believe they had a KPA800 and KPA1500 at the Hamvention in 2006. And in 2007, the K3 took centerstage. Time flies I guess. Doesn't seem like it was almost 4 years ago that the amps were shown at Dayton.

Re: [Elecraft] Elecraft Amps
It will be interesting to see what Elecraft decides to do. It is a strategic market question. There are a number of amp solutions currently. I'm sure that the K2 K3 owners using them have applied the necessary ingenuity to obtain satisfactory compatibility. Also a certain popular amp manufacture over-seas is discontinuing their 100 watt external amp probably due to lack of sales. As devices increasingly incorporate surface-mount technology and PIC processors, amps are becoming smarter. I have to say, Elecraft has made ham radio much more enjoyable for me. And I am keeping my eye out for what ever new items they decide to market.

Re: [Elecraft] Elecraft Amps
IMHO, the real reason for delay on an amp is that they have huge backlogs on things like the 144 transverter, and a possible market for several thousand P3's, if not more. One of the things that has killed many companies is trying to get big too fast, outrunning their momentum and neglecting their core markets. And you have to remember that they are still selling new K2's. What's that, a ten+ year product in a market known for obsolescence and throwing models overboard? And that in spite of four thousand sales of K3's from the same company at the same time? Only thing I can think of that sold for longer than that (not counting the change for the FCC's silly 10 meter ban) was the Heathkit SB220/221 KW amp. One can attribute that to an all-time classic engineering balance between cost, function and durability. If I wanted to bet on who knows to really float an amp or not, and how to do it, and what to put in it, I'll bet on Wayne and Eric :) 73, Guy.

Re: [Elecraft] Elecraft Amps
I have the Ameritron AL-1500 and it's a powerhouse. Used to have an Alpha 77SX and that was double this amp. I like to use power in contests but playing by the rules is a mandate so over the max legal power is of no value. I use a factory aligned LP-100A to keep me legit. This is not A QSK amp and the Ameritron QSK is PIN diode which will not handle a moderate SWR mismatch at higher power. I would love a SS amp by Elecraft for the QSK would be stellar and the amplifier would be quieter than this AL-1500. I would want it capable of 1500W and gravy would be to have it capable of running this power in a RTTY contest. Auto tune is not necessary if the QSK can operate under 3:1 SWR at full output. I would want it offered as a kit and would expect $2,400 as such, add 400 for AT. Gary KA1J Check please OK, I might as well document my personal wish list: 500W is more than enough.

Re: [Elecraft] Elecraft Amps
High power is helpful to hold onto a frequency. When another high power amp comes on and your power is lower, the amp helps, big time. I was a die hard QRP'er, but on lower bands when the conditions are not great, the amp makes a huge difference. I run a THP HL-2.5Kfx whenever needed and no second thoughts. When the bands get better, my electric bill will much lower. I agree about the comments of Elecraft designing a do it all amp including the remote tuning option. The day that happens, The THP might, not likely, but might hit the used market. Hard to part with a perfect output design like this particular THP. I have tried the rest. Perhaps the Elecraft amps will use similar design, then who could resist a build it yourself amp, I couldn't.

Re: [Elecraft] Elecraft Amps
Let me add another data point why a KPA800 makes sense: I only have 120V in the shack, so I would like to see a solid state amp that can do 800W with a built in power supply. That's probably the max you can get out of that circuit 15A * 80% *120V = 1440W max continuos. At 50% efficiency you can do about 800W with that. Adding 220V (208V) is not an option for me and maybe a lot of others. I already have a TT Hercules II 500W solid state amp, but it runs of 12V with 90A off a battery that is trickle charged.

Re: [Elecraft] Elecraft Amps
Considering the fact that the Ameritron ALS-600 lists out at $1500 ($1250 street price however), and is NOT QSK (but easily converted to such with the mod by Phis Salas), I think you are dreaming! $1K would be pretty cheap, and Elecraft doesn't make cheap stuff. Personally, I think you would be looking at somewhere close to twice that amount! But hey folks, let's all take a Valium! Elecraft has been consistently super-cautious about what they produce, and when they produce it. I know they are tinkering with amps, but that's all we really know at this point--they are tinkering. It could be a year or two before anything really starts to look like a possible production piece. Remember, this is a company with two (count 'em, two) principals. It's not Yaesu, or Icom. I think they prefer to not spend 23 hours a day in the lab! Someone mentioned earlier the concept of return on investment (ROI), and I would add allocation of resources. Although they have added a lot of great talent to the mix, it's still two guys primarily calling the shots, and doing the decision making. I think it's a bit unreasonable to expect them to start cranking out all the goodies everyone wants them to offer. In time maybe, but not on anything close to the schedule some folks are wanting. I'm not even sure amps are a really viable product for them to get all that fired up about. There are some very sophisiticated amps out there already, and I don't really know if Elecraft can truly distinguish themselves in that part of the market the way they have in the transceiver market. Seems like any innovation they might come up with would be much more easily copied/added by someone else, and there goes your market advantage. I think the Elecraft name on an amplifier would be significant, but it's high dollar and high risk. Personally, I think half or more of you, who are chomping at the bit to have an Elecraft amplifier, would fall by the wayside when you see what kind of price you would have to pay for one that has all these bells and whistles on it.

Re: [Elecraft] Elecraft Amps
Gang: Let's keep this conversation away from being a QRP vs. QRO, VK vs. W/K, etc. and admit up front that all power levels have their place. It would seem out of place to run U.S. legal limit on 40 cw ragchewing up and down the coast, etc. But then a small amp at 300-500W can be useful to keep the idiots from encroaching on your frequency. I have had a Tentec Hercules II amp for about 10 years now. In that time I ended up ignoring the Titan completely. (It finally was sold to N7TR as a fixer!) The Herc II is remote bandswitched with the OmniVI series and could easily be done so from a K3 with the Elecraft KRC2, etc. Having said that (one would think I am pushing for the 500W Elecraft amp...), I found the Herc II just a little underpowered in contest situations. So, from my view, a KPA800 or KPA1000 would be perfect. I have other amps and other transceivers but tend to pair amps/xcvrs by manufacturer (FT1000MP with Quadra, OmniVI with Herc II, etc.). My K3 would love to have an 800 to 1000W afterburner in Elecraft colors! Let's keep the autotuners out of the amp. I suspect the technology isn't stable yet.

[Elecraft] Elecraft K2 Bifilar Windings
I used this trick to evenly twist wires together for bifilar winding; 1, Trim the wire so both are the same length. 2, Clamp one end of the wires in a vice or have someone hold them with a pair of pliers. 3, Clamp the other end of the wires into a chuck of an electric drill (variable speed). 4, While holding the wire tight start the drill at slow speed and the wires will twist evenly. 73 Dave KD1NA Hi all, Quick question about the bifilar windings on the bifilar transformers like T6. How critical is the twist in the two wires? When I did T6, I was unable to get a terribly consistent winding of the two wires together. Build manual says they should cross over about every 1/2, but some parts of the wires ended up a little tighter than that, others less. On some of the windings when I wound the core, they more or less didn't pass over each other at all for one or two windings (tho they were adjacent). I'm assuming this is probably not super critical, but just curious. __ 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] Elecraft Amps
If you want this, its already out there. :) I purchased a 600w solid state kit amp, actually, it was a kit amp by happenstance. A brand new Ameritron ALS-600 that I had to do final QC on and replaced the original Slow-as-Moses TR relay with the AD5X full QSK micro switch board. It's a wonderful little amplifier (now), in all honesty, but I would have happily paid the same amount of money (circa $1,300) for something I could have built from a box of parts and directly interfaced with the K3. Building stuff. That is a lot of the fun in Ham Radio for me, because I don't have the time or tools to design and build from scratch. When I started in Ham Radio, I was a Heathkit junkie. I had a basement full of two tone green back in the late '70's, and the K3 has reawakened that addiction, now that the kids are grown and I have time again. -lu- Message: 7 Date: Thu, 11 Feb 2010 12:15:50 -0600 From: WW2PT ww...@arrl.net Subject: Re: [Elecraft] Elecraft Amps To: lawrence libsch llib...@bellsouth.net Cc: elecraft@mailman.qth.net Message-ID: 0b770874-a215-4116-8bb9-75002bdf9...@arrl.net Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes I'll weigh in, just in case the Aptos crew is taking notes and counting votes. ;-) An off-the-shelf, high-end appliance to compete with THP or SPE would be a high-cost, low-volume, low-profit venture, something I would not want to undertake in the current economic conditions if I were CEO of a small company like Elecraft.

Re: [Elecraft] K2 working on 40M
Garry and all - at least those who are building new K2s. Yes, the filter setup is a bit tricky, especially when using filter widths wider than 1.00 kHz. The reason is in the varactors that have shipped with the more recent K2 kits. What that means is that a filter width that is indicates as 2.00 kHz wide on the K2 may actually be 2.5 kHz wide (this is not exact, it all depends on the varactors). The result of this is that the LSB filter settings listed in the manual will be about right, but the USB settings will be way off. In other words, the manual settings will give you a workable filter for the lower sideband response, but will not work for the upper sideband (USB, RTTYr, and CWr) settings. (NOTE: the OP1 filter width is not affected by the varactors - there are no varactors on the KSB2 board). The only cure I know is to use Spectrogram or another audio spectrum analyzer to measure the actual width of the filter (in LSB or CW - not CWr - or RTTY - not RTTYr). When you use LSB, CW or RTTY, you should be on the lower sideband, and you can change the width without much movement of the lower end of the passband frequency. After getting the filer width as you like it, then refine the low frequency end of the lower sideband filter (by changing the BFO setting) and then set the USB BFOs to properly place the sideband. If you want specifics on how to set the filters, look at part 3 of the article on K2 Dial Calibration at my website www.w3fpr.com (while you are there, you may just want to go through the entire K2 Dial Calibration procedure which includes adusting the filters. I have not yet updated the webpage information to include how to handle this varactor problem, but since you can see the passband width on the Spectrogram display, it should be obvious. Just adjust the width of the filter until the actual width is what you want, and use the K2 display only as a relative indicator. 73, Don W3FPR 2rGarry wrote: Congrats on the K2 receiving on 40.

[Elecraft] New Products
I think Elecraft would be making a big mistake by going into the amp business anytime soon. I have a better idea. How about continuing to refine the K3 and work on getting the P3 Panadapter out. I have been waiting for months to order a P3. First it was going to be out by the end of 09 and then just after the first of the year. We are now halfway through Feb and I still don't know how much it is going to be or when I will be able to get my hands on one. I hope getting a P3 won't be like getting a K3 when they were first announced. I'm talking about placing an order and getting it 6-12 months down the road. That deal made me put off buying a K3 for more than a year, almost two years. I instead bought a IC756P3 which I still have and love. As it turned out, I'm glad that I put off ordering my K3 #3494 because of hardware mods etc. I do love my K3 but I wish everyone would let the Elecraft team finish what they started before they bombard them with all of these brilliant ideas. My restored and updated Drake L-4b my Ameritron Al-80B both work great with my K3. There are many great amps on the market to choose from and how much demand could there be for an amp that cost 10k or more??? Very little IMO. By the way, this economy is going to be in the toliet for a long time...food for thought. I'm not a doom and gloomer, just realistic. 73, Tom kd0bcf. __ 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
