Re: [Elecraft] Buying a K3 in the UK?
A local dealer has to add value to his service. And if a customer does not want that particular service, he should not be forced to buy it. I have always purchased directly from Elecraft and have never had the slightest problem. On the contrary, they have always provided a splendid service. It is good news if WS becomes an Elecraft dealer as it provides a local service to customers who may not want to deal with the perceived hassle of importing from the US. It is very bad news if those who wish to deal directly with Elecraft are prevented from doing so. It's about choice and, dare I say it, a free market. I trust Elecraft to continue to give us the choice! 73 Ian G4FSU -- Geoff, Even if WS did know that someone in the UK was dealing with Elecraft directly, I very much doubt that WS could or would want to do anything to prevent that person from doing so. My understanding of exclusive in this context, is that WS have been chosen/ asked/ appointed by Elecraft to be the sole dealer in the UK selling Elecraft's products. If Elecraft have not done this, then exclusive IMHO should not have appeared in the announcement. 73, Geoff LX2AO On May 29, 2012 at 10:56 AM, Geoffrey Downs G3UCK wrote: It's not necessarily excellent news for the UK.

This is considered bad form in the bicycle world and I assume it is the same in the Ham world as well. It is unfair to the dealer who has invested money in having stock on hand to for you take advantage of his investment and then give him nothing in return. At least buy something else from him even if small. If you want a local shop to be there when you need something at a moment's notice you need to spend money there at other times. If it costs a little more, that is the price of keeping him in business. I will admit that if the price difference is too great you are justified in taking your business elsewhere.

Re: [Elecraft] UK Re-seller
Not exactly local - good 2 hours drive for me (in UK, that considered longish). however, I would expect that most UK hams have bought from this dealing at some time in their radio lives and probably quite a bit. We just don't seem to have 'local' shops like you guys do, although I do have another one only about 30 mins away.

Re: [Elecraft] Buying a K3 in the UK?
A few years back I bought a couple of KB9YIG's little SDR receiver kits (one still in use as a panadapter for my K3..).

[Elecraft] K3 psk D splater
Last evening I was trying another aspect of my K3I often work PSK using AFSK but I thought Id give it a try using PSK-D using Kcomm I set everyting and it was decoding fine on the K3 display and in Kcomm.There was a strong station that was calling CQ so i gave him a call while having a good QSO he mentioned that I was splattering a bit and I should not drive as hard. rather than explaining that I wasnt using AFSK I just quickly said thanks Ill look into it and 73. Question, What can cause splatter when using PSK-D I had the power dialed to 25W so I certainly wasn.t running to much power, and just to be sure that I was actually using PSK -d I had pulled the audio line in/out from the K3. Am I missing something? I will be trying again hooking my other rig up to another computer so that I can monitor my output in Fldigi, just in case he was seeing issues at his end.

Re: [Elecraft] UK Re-seller
If I was to make the journey all the way to WS I'd probably end up picking up something. But I can't see anything wrong with going to look at something in a shop and then buying it off the Internet, I do it all the time, if they charge a lot more than online. If there's a small premium, it's worth it for getting the item immediately, but if they are making a 30% profit or so, no thanks. I don't think there's anything wrong about doing this at all. What I've done successfully in the past though, is go to a store that has something I want, confront them with the online price, and end up getting a good deal from the shop (a bit more than the online price but getting the item straight away). 73, Thomas M0TRN On 30 May 2012 12:32, David Christ radio...@mchsi.com wrote: This is considered bad form in the bicycle world and I assume it is the same in the Ham world as well.

Re: [Elecraft] FW: HEAVY KNOBS??
As Eric reported, my assumption was wrong; the Elecraft encoders have ball bearings in spite of their small size. IMX quality ball bearings make a big difference in their ability to handle weight without excessive wear in designs with significant side-loading (such as a heavy knob rotating a nominally horizontal encoder shaft). Fred makes an excellent point about removing the heavy knob if the rig is shipped. Inertia is an amazing weight-multiplier. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil LaMarche Sent: Wednesday, May 30, 2012 6:45 AM To: elecraft@mailman.qth.net Subject: [Elecraft] FW: HEAVY KNOBS??

Re: [Elecraft] K3 and KX3 AGC settings and what the really mean.
Hi Ron, I'll be documenting these better in the next KX3 errata. In general we recommend using the defaults. Here's a quick summary: AGC Decay: soft No equivalent in the KX3. In fact probably not needed even in the K3 thanks to recent K3 and KX3 AGC improvements. Hld: 0.2 (AGC HLD, default 0) Hold time in seconds for voice-mode AGC. This prevents AGC decay for a specified time, which some SSB ops like. Pls: nor (AGC PLS, default NOR, just added with the 1.01 MCU release) Noise-pulse rejection. Prevents the AGC (and S-meter) from charging up on one-shot noise events. Try turning a noisy florescent lamp on/off right next to the radio; with AGC PLS set to NOR, the KX3 should suppress the usual long-decay S-meter response to such pulses. Set it to OFF if you want to see what happens to most radios :) Slp: 0 (AGC SLP, default 15 on the KX3) The higher the slope number, the flatter the AGC response is. With a high setting of slope, signals above the AGC threshold will be held very close in audio amplitude even if they vary by many S-units at the RF input. Thr: 20 (AGC THR, default 5 to 7 depending on firmware release) This specifies the threshold at which AGC starts to attack. A higher number moves the threshold up. F: 200 (AGC FST, default 120; or AGC SLO, default 20) Specifies the decay rate for AGC slow or fast as selected by the AGC switch on the K3 or the AGC SPD menu entry on the KX3. A larger number means a faster decay rate. AF lim: nor 030 (AF LIM, default 30) Sets the audio limiter threshold used when AGC is turned OFF. Not yet implemented in the KX3.

Re: [Elecraft] K3 psk D splater
The short answer is that splatter can be caused by just about anything between your keyboard and his audio out. Analyzing just one occurrence is nearly impossible. There is a lot of good verbiage in the archives about keeping your signal clean and maintaining a means for inspecting that yourself. The desired answer to the other station's report is I monitor that constantly, and my signal is clean leaving. What do you get when you monitor your own signal? Do you have something to do that, and do you know how to use it to get correct readings on yourself? Beyond that, even going through one amplifier means that IMD products will be down 35 dB for a well functioning amplifier. When your signal is S3 or S4, the IMD is way down. If the other guy was loud, then your primary signal, even at 25 watts, is likely s9 or maybe even 20 over. In that case even that -35 dB can sound like a local signal. If he's doing what so many people seem to do, run his preamp constantly on, RF gain max all the time, his RX, even a K3, can add 20 dB to the IMD on your signal, ESPECIALLY if using SSB filters for RX. But if you are not perfectly clear and measured about what you are transmitting, that argument won't go anywhere. Again, belaboring intentional, trick is to not have any questions about the signal you are transmitting. Even better you have graphics on it, and can send it to him in an email. 73, Guy.

Re: [Elecraft] FW: HEAVY KNOBS??
Phillip and others, The original K3 knob is adequate in my opinion. As a matter of fact I have an extra. I acquired a K2 where someone had put a K3 knob on it (Which I did replace with the newer K2 weighted knob from Elecraft). I am sitting here with the spare K3 knob in my hands and cannot for the life of me see any advantage to an even heavier knob. Proper adjustment against the felt washer works for me….But to each his own….. 73s Jim, W4ATK On May 30, 2012, at 8:44 AM, Phil LaMarche wrote: I questioned the problems possible caused by heavy knobs.

Re: [Elecraft] P3 SVGA interference -
I can agree with you regarding the IF oscillator oscillating since when I approach the coax it changes the conditions stopping the oscillatoin. BUT - if it was the P3's IF amplifier going into oscillation I would expect the display to freeze as no IF signal would be able to pass. That does not happen. The P3 and SVGA continue to operate as it should but has the extreneous signal displayed. I am convinced the ribbon cable signaling was inducing a signal onto the shield of the internal IF coax. Moving the ribbon cable away from the IF coax cleared the whole problem up. All is as it should be now. 73, Bob - W6OPO -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-interference-tp7556731p7556776.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] FW: HEAVY KNOBS??
What I get out of a weighted knob is related to a car accelerator or throttle body that sticks with first pressure on the accelerator -- you always get a jerky start.

Re: [Elecraft] FW: HEAVY KNOBS??
I tried both kinds of knobs for an extended period. I used the standard knob with very light drag from the felt pad so that I could spin it easily. It was easy to spin and stop precisely. The heavy knob spins for much longer, but at first I found it was harder to stop it where I wanted it. I have kept the heavy knob because I like the feel of it when turning more slowly. Both it and the standard knob are well-balanced so you can use them with very little drag.

[Elecraft] INTERNET PURCHASING
David is absolutely right (frighteningly right) and unless people start understanding the ramifications of what they are creating each time they purchase something over the internet they will find themselves living in communities as blighted as Detroit. Internet sales are almost universally tax-free which means local communities are deprived of revenue crucially needed to maintain quality living for their citizens. Every time you think you save a buck by ordering online, you actually hurt your local schools, hospitals, fire departments, special learning centers, and all manner of charities.

Re: [Elecraft] K3 psk D splater
Just to add to my original question and this may come out when I test it using the other radioHow much power can you safely use with PSK-D.

Re: [Elecraft] INTERNET PURCHASING
And, I'm bound to say that it seems to hurt most when buying from Elecraft! Some overseas purchases get in 'under the radar', including high value items at times. What really hurts though, as Geoff has written, is the fact that the UK government earns 20% of the shipping cost too! Other EU buyers will have the same gripe. Which brings me back to an old topic of shipping costs from Elecraft. I have bought quite a lot of stuff from the USA over the years, and have even posted stuff home to the UK when I have been in the USA, and it has never seemed that expensive to me. I have raised this with Sales in the the past and have been told that it will probably end up being cheaper to ship than the original figure quoted, but that doesn't seem to happen in practice. As an exercise this evening, I priced up buying a KX3 from QRP project in Germany and compared it with the total cost of buying it direct. I have done this sort of comparison before and found that the convenience of buying from a european reseller comes at a premium, but since the exchange rates have moved in recent weeks (and in my opinion only back to where the pound:euro should be), it is now cheaper to buy the KX3 from Germany rather than direct. How long that situation will last is anyone's guess! Equally, whether the same will be said of Waters and Stanton's pricing remains to be seen. Finally, it has always seemed to me rather bizarre that someone buying something in the USA from another state does not pay sales tax. So I have every sympathy with the 'small town' shopkeeper losing sales. Personally, so long as I don't think I'm being really ripped off, I will buy from the local store every time. It's unfortunate that the sales tax system in the US appears to discourage buying anything 'in state'. 73 Stephen G4SJP On 30 May 2012 22:01, Geoffrey Downs geoffre...@madasafish.com wrote: Dear Kent, Internet sales are not tax free in the UK.

Re: [Elecraft] INTERNET PURCHASING
And don't forget from the USA (or anywhere outside the EU) we also have to pay the Import duty first (on anything over a few dollars). The 20% is then charged on the lot, not just the original price but price plus shipping plus duty. The duty will depend upon how the item is categorised - which depends on the exact wording of the customs declaration. Word it badly and we pay loads!! Then there's the rip off 'administration' charge from the postal company. That could easily be around $60 on top of everything else dependant upon which shipping company is used. And there's no choice - whoever the sender chose and whatever fees they paid, the shippers will add their cut. Can add over $100 to a what seems to be a simple $150 order!!

In the state of Ohio internet tax is required. The company may not charge it but it is up to you to pay it. Also if a company has a presence in your state the tax will be taken out at the time of purchase.

The other two are PSK D which is created entirely within the K3 or it's sound card version DATA A. Both of the D or direct modes can be used with paddles on the K3 to send and receive while decoding is done in the K3. They can also be used with the K3 Utility and some other software that sends text over the serial cable, I believe.

Re: [Elecraft] AGC
I think that's an unwarranted generalization. People who use automatic systems don't necessarily do so because they don't understand what is going on ... they may use them because they are faster, less prone to error, or free up hands/attention for other simultaneous tasks. AGC is a good example of that. If I'm operating at a high rate in a contest I want to use my hands for typing or tuning instead of riding the RF gain control. Non-skid breaking systems on vehicles are an example of an automated system that WILL save your life, especially as you get older and slower to react. I'm pretty old myself, and I can pretty much guarantee that the only thing that will change when we oldtimers are gone is that another group of folks will take our place to pontificate on how much better it was the way they used to do it.

As a photographer, pilot and ham with digital systems, sometimes the old trusty proven ways are still the best. Auto, Automatic, Automatic tuning, focusing, autopilot are simply generalized systems to help those without cosmic understanding of the verities. Beware of AUTO, manual operating and understanding of RF Gain, AGC and filters will often do the trick. Auto is for folks who don't understand manual mode.

Manual for those of us who know systems is still the best. Experience counts. Auto will never pull you out of an accident, bad band conditions or a lousy picture.

Re: [Elecraft] INTERNET PURCHASING
*Folks, Eric has stated on this reflector that customers will always have the right to purchase direct should they choose to do so. I think this is clear enough. Whilst businesses provide a valuable service to your local community, there are many of us (myself included) who are on a fixed income with little discretionary income and when we see a price differential of 30% (more or less) on an item costing 3K in our local currency it gives us pause to think again before handing over the credit card. Experience in VK has been less than encouraging over the past decade as the dealerships here appear to not hold stock of spares for obvious reasons (cost) and to my knowledge none of them are authorized to carry out warranty repairs and the 'other' manufacturers do not allow warranty work to be carried out by the owners or dealers without the risk of voiding there factory warranty and this is also understandable. A call to your in-country dealer will only result in your being told to contact the manufacturer for all service/repair requirements. In simple terms, they sell boxes and accessories in baggies or boxes and that is the end of their responsibility, period! Elecraft have for years ( and still do at this point) sell direct only to VK and the number of transceivers and other products do sell well here and they enjoy an enviable reputation for both quality and support. I saw this first hand at a recent Hamfest where I was exhibiting the K-Line and had a full K-Line on air connected to a triband Yagi and the positive comments received were flattering to say the least. Interestingly, the knowledge of Elecraft equipment by non-owners was high given the number of Hams who spoke to myself and Jeff (VK4XA) and I hope that in some way Jeff and I were able to generate further business for Elecraft. We were both asked a couple of times if there was a dealer for Elecraft or if we were a dealer and we explained that they simply had to go on-line direct to purchase and I do not speak for Jeff but I personally did not a single negative comment regarding this arrangement. I did not hear anyone state they would only buy from an authorized dealer. In VK we have been subjected to a war of words between factory authorized dealers and parallel importers. (parallel importer meaning a business importing equipment acquired from overseas new or used or unused/unopened). These folks have staged this war of word on the internet advertising sites, dealer advertisement in magazines and the list goes on. I think a lot of us in VK have grown tired of this type of commentary and feel it is demeaning and poor publicity for our hobby. Currently the dealers in VK sell the JA manufacturers equipment and a lot of the European and US manufactured amplifiers, antennas and accessories including Ten Tec. To the best of my knowledge Alpha do not have a VK dealer ( a quick check failed to find one advertising Alpha amplifiers) and there maybe more but my point is if manufacturers such as Elecraft, Alpha and any other quality manufacturers decide to sell direct only, and dealers in VK continue to sell other products then I see no need to shop locally over ordering direct from Elecraft. If they had a dealer here, that dealer would not survive alone selling Elecraft products, therefore they would be relying on all sales from all manufacturers to keep their doors open and so I don't see how Elecraft would benefit with increased sales. To 'show' Elecraft products is simply a case of gettiing exhibits into as many Hamfests as possible across VK and Elecraft have always shown a willingness to assist owners in providing a display at their local hamfest where those wanting to find out more about Elecraft products can chat with a customer without the inevitable sales pitch driven by profit. Making available a working product sure beats the dealers showing a plastic covered box, not connected to anything. This was a common comment I had at the Wyong hamfest this year and i will be hoping to attend both Wyong and the other big hamfest in VK3 2 weeks prior to Wyong. This is of course subject to approval from Elecraft...:-) The point I am trying to make is that buying Elecraft products locally in VK will most likely generate too few additional sales to warrant considering due to the war of words and one upmanship tactics on display daily here in VK. I know our cousins in ZL would be less than enthused with having to jump through the hoops to deal with an existing ham radio dealer here in VK. Despite the hype, we do love our cousins across the pond, even though they talk funny...:-) The comments in the above email are mine and mine alone and I hope nobody takes offense. 73's to all Gary * On 31 May 2012 06:37, David Gilbert xda...@cis-broadband.com wrote: I don't believe those are the same topic at all.

Re: [Elecraft] AGC and…CW Decode
I admit it. I love my CW but am CW Challenged. I was taught Morse code by the U.S.Navy in Radioman School and had to master 20 WPM to graduate. How I struggled. Finally after being set back two weeks I finally got 20 WPM and was able to go on to CT school for the balance of my training. I went straight down to the FCC office and got my general class ticket. Thankfully, the Navy decided to make me a non-morse operator in CT school and I spent the balance of my naval career as a CT O branch operator. I have been operating mostly CW since getting back on the air in 2004. I can copy call signs well at much higher speeds, but am most comfortable around 18 WPM for rag chews. I find that the CW Decode feature of the K3 to be a great assist to someone of my questionable talents. Most decoders suffer from an susceptibility to noise, so anything you can do to improve the signal to noise ratio is beneficial. The decoder in the K3 is one of the best I have ever used. When a K3 rookie friend asked for help in using CW Decode, I came up with a procedure I use for copy those weak DX signals. One note of caution, turning off the AGC without decreasing the RF gain before doing so, can result in a loud CRASH from your headphones or speakers. I also have the AF LIM set to protect my K3 AF amp. CW Text Decode on the K3 W4ATK style. 1) Set MODE to CW.- makes sense. 2) Set AF Gain and RF Gain fully CCW (counter clockwise, all the way to zero). 3) HOLD AGC (turns the AGC off) 4) If a special VFO B display mode is in effect CANCEL it. 5) HOLD TEXT DEC, the select CW 5-40(or 30 - 90) using VFO B. (You will see a small T below the CW icon on the display). 6) Adjust the threshold (THR) using VFO A, AUTO or 1 to 6. ( Around 3 to 4 works for me most of the time) 7) Tap CWT to exit. 8) Advance the RF GAIN to 50% or so. Advance the AF GAIN to a comfortable listening level 9) TUNE in a CW signal and adjust the RF GAIN for best copy. 10) After the signal is tuned in and copying, try reducing the WIDTH to 100Hz (0.1). Using this procedure I can copy some very weak CW signals, weak enough to not be easily discerned on the P3. As I move about the band looking for contact I widen the selectivity as needed and ride the RF gain.

However if you buy from a VENDOR of their product and that vendor is not in your state, you will pay no sales tax. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member The marvel of all history is the patience with which men and women submit to burdens unnecessarily laid upon them by their governments. -- George Washington -- On Wed, 30 May 2012 22:22:25 +0100, Stephen Prior eastbrantw...@gmail.com wrote: [snip] Finally, it has always seemed to me rather bizarre that someone buying something in the USA from another state does not pay sales tax.

IMD increases with power output from any rig, K3 being no exeption. - Did the station that complained about splatter have his noise blanker and/or preamp turned on? If so, the problem might be on the receive end of the path. Both issues beg to be investigated. And yes, with direct PSK-D modulation, the soundcard output from the K3 is moot, however, the soundcard input to the complaining station is not moot, in fact, it is critical, as pointed out by K9YC.

Re: [Elecraft] K3 psk D splater
I take it your running a typical 13.8v supply. Running a stiff 15v supply cleans up the K3 TX IM3 dramatically. The filter also keeps the key signals clean into the K3. You say the guy was talking bars on the psk signal. I guess he may not know what he is talking about. Next time you get a bad report, ask them to email a screenshot of your signal or report how wide it is. PSK-D is usually exceptionally clean, and the fix items I mentioned will ensure it stays that way. Loud (bars) does not mean wide. Why do you take notice of idiots like that with stupid non-sense reports. If you turn down your power he has less bars and now your signal is clean. Is that how this guy relates? You assumed he was right regarding your signal, because you asked here regarding answers, and it appears you are not interested in improving your TX IM3 dismissing the proven fixes. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-psk-D-splater-tp7556767p7556811.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] UK Re-seller
I don't know how it is in the UK or the rest of Europe, but local electronics stores, much less those where amateur radio equipment is sold, have been gone for many years. They have been replaced by national retailers like HRO and AES. Back in the 50s and 60s, when I was growing up, we had a large, local wholesale electronics store that would do business with hams and CBers on a retail level. That's where I bought my first ham equipment, including receiver and transmitter, antenna, coax, and other accessories. Of course, they are gone now. I was surprised to learn recently that their largest account was with General Motors. So, when the Buick factory and several supporting factories in town closed, I suppose they did, too. In 1975, when we moved to southern California, a friend and I would drive toward Los Angeles and visit as many as four stores where ham gear was sold. Today, pretty much there are two: Ham Radio Outlet and Jun's. This, for the second-largest metropolitan area in the US. Point of this long dissertation is - if you have a local dealer and want to see it stay around, patronize it. Too many times, guys would go in and look over the equipment, then call every toll-free number that they could find, in order to get the lowest price or escape the sales tax. 73 de Jim - AD6CW On 5/30/2012 4:32 AM, David Christ wrote: This is considered bad form in the bicycle world and I assume it is the same in the Ham world as well. It is unfair to the dealer who has invested money in having stock on hand to for you take advantage of his investment and then give him nothing in return. At least buy something else from him even if small. If you want a local shop to be there when you need something at a moment's notice you need to spend money there at other times. If it costs a little more, that is the price of keeping him in business. I will admit that if the price difference is too great you are justified in taking your business elsewhere.

Re: [Elecraft] K3 psk D splater
David, I don't know what the max power would be before the internally generated PSK would produce too much IMD but I never use more than 50W. I thought you mentioned in your original post that you were running 25W and that would be fine. I have to wonder just how reliable is the receiving station. It could be you have a very strong signal at his place or, as someone else mentioned, he might have been running an agressive NB or similar. You may have trouble monitoring your signal locally so what I would do is get back on, make another QSO and see what the new partner has to say. I would be happy to sked with you if you think that would make the test easier. Send me an email off list if you would like to do that.

[Elecraft] K3 Woes: Radio Shuts Off at Power Levels 20 Watts
My beloved K3 is giving me fits. It was recently returned from Elecraft service for some 8v regulator capacitor replacements. This was done in April. I have been operating the K3 on just a few occasions since then. Last night when attempting to tune up, the radio would shut down if the power output was set higher than about 20 watts. At lower power levels the radio would tune. SWR on two different antennas was 1.2:1. The display also showed significant dimming even at low power tune up attempts. I have done a factory reset per the manual and reset the parameters in the Config menu. I have done the reset twice. I have switched out external power supplies (from a Samlex 1223 to a Powerwerx SS-30DV). I have fabricated a new power supply cable from the supply to the radio; still no joy. Before contacting Elecraft service, I would appreciate any suggestions of something (obvious) I may have overlooked.

Re: [Elecraft] UK Re-seller
KENT TRIMBLE wrote purchase something over the internet [and find yourself] living in communities as blighted as Detroit. This thread is way off topic (Ham) and getting into politically areas more suited to Facebook. This is practice is also frowned upon. I am reluctantly jumping into the fray only because I cannot let some statements go unchallenged. Detroit's blighted condition has NOTHING to do with people buying locally, even if by local you mean Americans buying US made products. Detroit is blighted because of government taxation, regulation and the government's strong arm support of the labor monopoly (unions). If government would get out of the way, Detroit could rebound in just a few years. Perhaps they could start producing the products people buy from the Internet. Dallas has a thriving economy in the midst of an economic depression even though Texas oil wells are producing a fraction of what they used to. The reason is the governments of Texas and Dallas are not standing in the way of businesses. Having said all that, I do agree completely with David Christ. If you walk into a store and notice the prices are higher than what you are willing to pay, then you should immediately exit the establishment. To do anything less is theft. If you want to buy online, fine. But don't steal the time or resources of a business you have no intention of patronizing. -- View this message in context: http://elecraft.365791.n2.nabble.com/UK-Re-seller-tp7556761p7556826.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] K3 fsk D splater
I answered Adrian off list. The topic read PSK not FSK at the time. This is what I had sent: -=-=-=-= PSK is not key shifting. That is FSK. PSK involves more than two unique tones, which means audio (phase) shifting; both on sending and receiving. It may be hidden in the -D modes, but audio is still en/decoded. The same is true for FSK (RTTY) decoding; the DSP detects the tones and durations to effect decoding. Ditto CW decoding. Only the K3 and a couple other radios can do this with no other software so most folks use a soundcard. I use a soundcard most of the time so I can watch the entire audio band for the station(s) I want to work. We're fortunate that we have the digital mode ability in the K3. I've only used it a few times, pretty cool feature. If the transmit audio and/or the receive signals are flawed, the transmission won't be properly decoded. If you can get a fine enough resolution on the P3, you can see the flaws, but most people use software which gathers the data from a soundcard. And properly setting those up appears to be more than some folks understand. Many soundcard folks overdrive their audio into their transmitter and others overdrive the soundcard from the receiver so the signals appear faulty (when it might just be the receiving station). If everyone (soundcard users) carefully set their levels, there would be fewer complaints. However, once a soundcard is properly set up, it's easy to see how many 'bad' signals are out there (quite a few). Others complain of folks running too much power, but that isn't a factor; signal cleanliness is the issue. I defy anyone to tell how much power is coming out of a clean station, be it 1/10 watt or legal limit. Signal strength isn't even a valid test because it could be band conditions, transmit and/or receive antennas or many other things. i.e. What's the difference from 100 watts into a dipole versus 10 watts into a 4 element beam? Answer: Not a darned thing except the beam focuses the energy. The inline signal strength is exactly the same. Most also have no clue how to notch out or otherwise remove LOUD signals (tripping an ALC response) so they can copy the weaker ones. The K3 makes this simple too; adjust the hi/lo cut, narrow the bandwidth or use the notch filter manually. Or do all three. Gee I like the K3; they thought of everything except the operator who understands how to USE what they've built. I'm getting there. ;o) -=-= So now all y'all know what he meant.

What size wire (AWG) are you using for DC power? How long is it? Include every part of the wiring between the K3 and the power supply terminals. The DC power lead should be short and fat -- at least #12, #10 is better, no longer than 3 ft total, and shorter is better. Are you SURE there is no problem at a connector? FEEL the connectors after you have transmitted for a while and see if any are warm. What does the K3 voltmeter read when you're receiving but not transmitting?

Most of us have a good one plus a cheapie that we don't mind dropping off the tower. :) Last I looked I had at least six. 73, Jim K9YC __ 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] K3 / P3 Bug?
Hi, A few weeks ago I upgraded my P3 and K3 to firmware P3 MCU: 1.16 and K3 MCU: 4.48. Since then, when I try to observe my Rb oscillator's 5th harmonic at 50 MHz, the P3 flatlines (no baseline noise at all, just a flat line), and when I try to adjust the Span of the P3 display it shows nan next to the span readout and refuses to adjust. Is this a known bug?

[Elecraft] [K3] SO2R Controllers
I want to try out S02R, and need some inputs on SO2R controllers. It will be controlling two K3's. I am considering the microHam micro2R and the Top Ten DX Doubler. Each has its advantages: micro2R: Capable of CW, FSK, SSB. Includes WinKey keyer. Appears to have a lot of active support from Joe Subich. DX Doubler: CW SSB (I can work the FSK interface). I like the manual mode that does not appear to require any computer connection. Device and K3 cables available at a reasonable cost. Any inputs would be greatly appreciated, - 73, John, N0TA __ 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] UK Re-seller [End of Thread]
Folks - we are drifting OT. Let's end this thread for now. 73, Eric List Moderator --- www.elecraft.com On 5/30/2012 5:33 PM, KD0RVF wrote: KENT TRIMBLE wrote purchase something over the internet [and find yourself] living in communities as blighted as Detroit. This thread is way off topic (Ham) and getting into politically areas more suited to Facebook. This is practice is also frowned upon. I am reluctantly jumping into the fray only because I cannot let some statements go unchallenged. Detroit's blighted condition has NOTHING to do with people buying locally, even if by local you mean Americans buying US made products. Detroit is blighted because of government taxation, regulation and the government's strong arm support of the labor monopoly (unions). If government would get out of the way, Detroit could rebound in just a few years. Perhaps they could start producing the products people buy from the Internet. Dallas has a thriving economy in the midst of an economic depression even though Texas oil wells are producing a fraction of what they used to. The reason is the governments of Texas and Dallas are not standing in the way of businesses. Having said all that, I do agree completely with David Christ. If you walk into a store and notice the prices are higher than what you are willing to pay, then you should immediately exit the establishment. To do anything less is theft. If you want to buy online, fine. But don't steal the time or resources of a business you have no intention of patronizing. -- View this message in context: http://elecraft.365791.n2.nabble.com/UK-Re-seller-tp7556761p7556826.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 __ 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] INTERNET PURCHASING
There are NO = NONE = NADA ham radio equipment dealers in Alaska. So - ordering equipment is either On-Line or by Land-Line (telephone), according to one's preference. Of course our Local Dealer is only 2400 miles away in Seattle! No problem 12-days RT drive (or $500 air-fare) and only $540 worth of gasoline later you are supporting the tax-base of Washington (and communities in Canada) instead of your home town. Oh, better add hotel and meal costs in there. BTW there is no state sales or state income tax in AK. Schools are financed thru property tax, so buy your home locally and not thru the internet! HA! Oh, senior's are forgiven property tax up to $250K valuation. I guess 45-years of taxes raising a family is adequate. Regarding dealers: The whole deal of stocking inventory is to get a wholesale price which gives the retailer a mark up (called gross profit). Some manufacturers subscribe to Fair-Trade which means the price is fixed by the manufacturer so it will not vary from dealer or direct. I particularly dislike this practise since it is anti-competitive. (sort of like all gas stations having the same price on their pumps). The buyer votes with his dollars! Why should he pay more than need to? POS outfits offer immediate gratification - at a price. Certainly one should weigh custom's duty and shipping when doing competitive pricing. ALL (successful) businesses do! Is this hard on local businesses? It can be. But this is reality - no getting around it. Support your local businesses but be smart with your money, too! The new merchandising model is direct-sales via internetbetter believe it! 20-years ago it was catalog sales. 100-years ago it was local sales. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
