[Elecraft] clifton labs
We bought a short lo-band E-field whip with pre-amp from Clifton Labs a few months ago, and two circular antennas a few weeks ago. All are well-built and the whip has performed well; it feeds the VE7AB RBN node. The circular antennas are still being tested.

[Elecraft] K3 NR needs improvement
I'm a CW op, I'm baffled by the comments critical of the K3 NR, APF and notch filter. The NR generally removes ALL random noise, meaning that the rcvr is silent in the absence of signals. Admittedly, It does get a little upset in the presence of many strong signals, so I usually turn it off in pileups. The notch filter can be tuned manually to silence one interfering CW signal. The APF is a bit tricky, you need to use fine tuning [ 3 digits after the VFO decimal point], tune SLOWWLLY and listen for the weak signal to pop out of the noise. But pop out it does.

[Elecraft] computer - P3 - K3 communications blues
I have a Windows XP box connected to my K3 using a USB port on the box and a Prolific USB-to-Serial adapter. It all works FB, N1MM Logger and SKimmer talk to the K3 via LP Bridge and the USB/serial link perfectly, including N1MM keying the rig. THEN I hooked up my nice new P3 today. It talks to the K3 FB - it gets freq data from the K3 and sends VFO changes to the K3. Everything else I've tested on the P3 also seems to work FB. HOWEVER, the PC cannot talk to the K3 THROUGH the P3 - via either the Prolific USB/serial link - or via a purely RS-232 link using the serial port on the windows box, which I also tried. [Just in case it was a USB incompatibility issue] K3 Utility running in the Windows box polls the K3 via the link and the P3 and gets no response. Everything is set to 38,400 baud, 8 data bits, 1 stop bit, no parity. The P3 is running the firmware which was installed at Elecraft, it was shipped to me a week ago. Any suggestions - please?

[Elecraft] Elecraft Price Increase - My 2 Cents
Interestingly, I have never compared Elecraft prices (K2, K3 and KX3) with competitive radios. Perhaps that is because I didn't see any genuine competitors to the K2 - a kit! plus a great little cw rig, the K3 - also a kit, plus great specs, nice size, great support, and leading DXers and contesters using it, or the KX3 - is there anything remotely close to it out there? So in my case the competition is not acting as a brake on price increases. There isn't any. So, Elecraftcan raise prices until I decide I can't afford the radio and take up stamp collecting.

Re: [Elecraft] K3/KX3 Operating Tip: APF (audio peaking, filter) for weak-signal CW work
Graham said: How about making it possible to switch the APF on and off through a programmable function button Dick said: It should be possible using a command macro.

[Elecraft] more Bass in K3 with PR-40
Rich said: intelligibility is concentrated around 1-2K Hz. Yes? I think so.

That became the basis of the A/D converters which in turn fed the T-series [T-1, T-2 etc] of digital transmission systems for the telephone network.

[Elecraft] Parting shot
Precisely!!! I'm trying to diagnose a K2 fault at the moment. I'm largely acting as a robot directed by Don Wilhelm, thank goodness for Don& Gary. I would be even more at sea, out to lunch, if I were trying to cope with a fault in the far more complex K3. I've read the K3 manual carefully [fb user manual!] and I still don't have a clue as to circuit level function, sufficient to infer fault from malfunction. [I did my PhD thesis on electronic fault diagnosis& co-wrote the first book on the subject . . .] ERIC VA7DZ [PhD in EE, F.IEEE, FEIC, P.Eng., etc etc] I'd like to see a K3 service manual, or at least a comprehensive circuit description. Without some explanation, the downloaded schematics are pretty worthless to somebody trying to understand the radio. In particular, the published K3 block diagram is an exercise in obscurity. In my opinion, it's nearly impossible for someone even to follow the receive or transmit signal path. 73, Jim W8ZR -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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] Need for advice was; noise reduction
Dear Joe With respect, it seems to me that the secret sauce in the K3 is largely in the FIRMWARE, which is why I carefully avoided even mentioning it, let alone asking for descriptive material on it.

Besides, competitors would have to sell K3 or K3 superset hardware to make direct use of it. I also trust that Elecraft has filed patents on the appropriate items, and will defend them vigorously.] If much of the proprietary advantage lay in the HARDWARE, would Elecraft publish a complete set of schematics? They would not. [Fault diagnosis would be done entirely by Don and Scott telling us to measure voltage X at pin Y.] As you noted, a set of schematics, plus a working K3, plus a half-decent lab, is all that a good electronics/rf engineer would need to develop the 'what' and 'how' information which I mentioned. So, the information you are worried about is already out there. Finally, Wayne & Eric would, I'm sure, keep mum about any really subtle, obscure yet critical bits of design. The text would just make it easier or possible for us amateurs to understand the design, and more important, the design choices, why the K3 was designed the way it was. BTW, I think that seminars at Pacificon might be an even better way to give us this insight, as one of the Sams proposed. 73 Eric VA7DZ The On 07/12/10 9:54 PM, Joe Subich, W4TV wrote: > >>> While we're on the topic, I would really like to have a text >>> describing the design of the K3, an aid in understanding what the >>> components do, the design choices and why they were made, WHY >>> modules were designed the way that they were, and HOW they work at >>> the component or group of components level. > > This is absurd!

[Elecraft] Elecraft sales -- commissions!
Eric You've convinced me! When is the stock offering - so I can buy some Elecraft Shares? [I've been selling Elecraft radios for free and I'd like to cash in, to get paid for it. Owning the stock would do the trick. Please? ] Eric Manning VA7DZ Eric Swartz said: We are well past working from our basements.:-) A few data points: 1. Since shipping our first K2 from Aptos in January of 1999, Elecraft has grown into a healthy multi-million dollar high-tech company with a broad product line. We have -zero- debt, own all of our inventory, and have a healthy, and very stable, balance sheet. We build our products here in California, just outside of Silicon Valley. We are structured to be here for a long time, and certainly longer than most hams keep a particular rig. We want Elecraft to outlast both of us. 3. How did we do that? Elecraft designs great, high value, products that are fun to use. And our products, like the K3, continue to improve and get new features even -after- you buy them. We run a stable and tight financial ship - carefully trading off an internally financed growth rate versus risk and cash needs. We work hard. We hire great people who continually amaze us with their intelligence, creativity and work ethic. Our customer support team is one of the best. And we enjoy our work. 4. We also carefully listen to, and interact with, our customers daily. We are focused on being the most responsive, and fun, ham radio company to buy from - period. 5. Wayne and I are both healthy guys - a very long way from retirement. We are having a great time bulding and running Elecraft, and plan to do so for some time. But we are not the only people who continue to make Elecraft successful. 6. Our well staffed engineering design team is diverse and strong. I'd wager that it is as large as, or larger, than many HF rig design teams at our competitors. We are well past two guys doing all of the design in our basement labs. Our engineering, support, manufacturing and management people are top notch, with a lot of depth. We have a great team and plan to keep building it for the long haul. 7. We haven't been a 'QRP Only Company' for some time. Yes, in 1999 we first targeted at the QRP market since it was tightly focused, easily marketed to, and was our fastest path to a first product. Its still a great market, too. But we always planned to also offer 100W high-performance rigs, both kit and factory assembled, to compete against the best HF rigs from other QRO manufacturers. That's the major part of the market. I think you can agree we have more than succeeded in that area with the K2 and now the K3. The majority of our rigs go out the door at 100W. We are continually designing a diverse product line, ranging from QRP to QRO. The KPA500, now going into field test, is definitely -not- QRP;-) But stay tuned for more QRP offerings too! 9. Most important, we have incredibly enthusiastic and supportive customers. You make it fun for us! By telling your friends about Elecraft, the K3, and our other products, you keep us in business every day. You are our best salespeople. The more you enthusiastically tell your friends about our products, in person and on the air, the more new products we can design and sell. In today's economic environment, more than ever, this is incredibly important to us. Please - keep up the great work. We really appreciate it! 73, Eric WA6HHQ www.elecraft.com -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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] My question is, "Do you folks think it is really necessary to , detail-inventory the Elecraft K2 product??
I think it's a good idea. The serious screwup is not being shorted by Elecraft for a 50 cent component, it is installing the wrong component somewhere. Doing a careful identification of all the parts by inventory is a good way to avoid this. You match up each component with its descriptions by doing the inventory and filing the components accordingly [I use muffin tins, with all of the diodes in the same dish, etc. You are less likely to install a diode in a resistor's place , or the wrong value resistor, if you do that. I find that modern, tiny components are harder to identify, and thus easier to confuse, than their huge 1960s ancestors were.

The only serious difficulty I have had in building a fully-optioned K2 and K3, was installing the K3 SUB rcvr , due to the spaghetti junction of TMP cables fouling the connectors, and also from pushing a TMP plug in a little too forcefully. I went thru 2 KRX3 boards and a lot of bad language before I got it right. An LED flashlight [Thanks, Gary!] helped a lot. A harness holding the TMPs in place and out of the way would be a great help, if feasible. A word to the wise: install your SUB AFTER you have installed everything else . Otherwise, installing that new filter or . . . is going to require you to remove and replace the SUB, yecch. eric VA7DZ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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

So, the built-in battery of the K2 allowed me to operate long hours, and recharge from the generator while I was asleep. The entire rig including battery chargers, key and mike fir nicely into a small hardshell case the size of a laptop bag - cabin baggage - and the Sigma 5 centre-fed vertical [which worked fb on the beach near the salt water] went into a sports bag which went as checked baggage.

[Elecraft] QSK THUMPS?
When my K3 switches between T & R in full QSK mode, I hear audio thumps. [The tramsmitted signal is apparently clean with no clicks; I always get good signal quality reports.] Now, My K2 has no such thumps; you can't tell when the radio switches between T & R by listening to the audio. The transmitted cw sidetone sounds just like any other cw signal, with no thumps or other noise. I would like my K3 to be the same. Is there anything I can do to attenuate the K3's audio thumps? eric VA7DZ K3 3620 + 500 W ICOM amp -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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] [Fwd: Re: USB to serial angst]
Gang It's been a great discussion and a real eye-opener for this naive academic, who assumed that USB is properly regulated by an IEEE Standard [it is not] and that a well-engineered, standard-observant and portable USB driver exists. [It doesn't.] Thank you all for helping to set me straight! The takeaways for me: *There is presently no feasible alternative to RS 232 as an Interface. Wayne & Eric made the right choice. USB is a non-starter, being FUBARd due to the lack of an enforced standard. What's more, * RS 232 is plenty good enough for the undemanding radio control or "knob-substitution" task. [Audio & video transmission may be another matter, but that's for another time.] * There's no call to sniff at RS -232 just because it's almost a half-century old. Unix [tm] is about forty years old, and still the reliability and efficiency champ. [No, I don't want to start a controversy on that!] * Desktop PCs are better than laptops for radio control, because you can fit RS232 cards to them. And laptops may have noise problems due to sloppy construction. * There are many - way too many - radio communication protocol "standards" - Kenwood, K3, etc etc. We must just Get Used To It [until YaeWoodCom sees the light and imitates the K3]. eric VA7DZ K3 3620 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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] the K3 is a very technical radio
"the K3 . . . is a very technical radio." It certainly is. My first kit shipment arrived in November, and I've been engaged ever since in building, testing, reading, dis-assembling, asking questions, scratching my head, dicking around with optional options in the apparaently endless parameter menus, and even a little operating. I've been interested, engaged, pleased and occasionally baffled and frustrated. It's been a steep learning curve but I've now [nearly] got it set up exactly the way I want it. It is to this time what homebrew was to the Fifties, but with much less aroma of melted solder. eric VA7DZ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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 Configuration - No mono plugs in the stereo spkr jack!
DO NOT, repeat NOT, plug a mono plug into the stereo speaker jack on the back of your K3. The manual says that the microprocessor firmware will switch the audio to SPKRS 1, which it will. However, if there are other events queued up for the cpu to process, it may take some milliseconds, during which time the shorted output may blow the audio amp, which is chip U1 of the DSP board. {What is the audio output doing on the DSP board instead of the I/O board? - but that's another story} You then get to replace the DSP board - like I did - which is good fun but a fair amount of effort.

[Elecraft] DX Test
Wonderful band condx! 20 and 15 were open to Europe, Asia and S America at the same time for hour after hour and noise was very low [S0 here] I heard no DX stations request UP or DOWN so there were big pileups smack on the DX freq. I had spotty luck in the pileups [only 500w and a yagi here, not exactly a Big Gun] until I turned on the TX incremental tune - down just a few hundred Hz to get me off the pileup freq - and my luck improved. THis also left the SUB rcvr free for diversity, which helped quite a bit with QSB and picking up callers off the side of the beam. eric VA7DZ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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] Super K3
IN 1954 I had the Walter Ashe Radio kit which comprised a 2-triode regenerative receiver [6SN7] , a 6AG7 - 6L6 rockbound transmitter on 40 and 80, and a single power supply with a 2-position switch. [That's called T-R switching!] The whole station cost aboot $50 and I really liked it. But I liked the NC-57 which I got next better, and then the HRO-5 better yet. But I had to use a BC-453 command set tuned to the IF as a back end to get enough overall gain to hear the noise. Ah, the good old days. [But I won't try to tell you it was better than the K3!

Re: [Elecraft] For you Anti-Scopes
Further to Julian's & others' comments about CW Skimmer removing the need to tune the band, a skilled part of the operating experience which is enjoyable to many [but not all!] of us: My friend is hot to write a software layer which will sit on top of CW Skimmer and which will win contests -- entirely on its own. Put another way, it is the next logical step after the PDP-7 program which did QSOs on its own, described in this thread. The amateur will just point my friend's software at a contest , hit start, and leave the shack. I know just enough about artificial intelligence and expert systems to believe that he very possibly can do it. Then what? Will we still enjoy contesting, knowing that computers will win every one? Maybe. Deep Blue - the IBM parallel processor - beat Garry Kasparov, but people still like chess. But do the Chess Masters [ the counterparts of the contest high-scorers] still like it as much as they did before Deep Blue? I haven't a clue, but somehow I doubt it. Will we outlaw it, like ARRL may or may not do with CW SKimmer?
