[Elecraft] [K2] Rework Eliminators(TM) Revisited
Now that both of our K2 Rework Eliminator(TM) kits are out of production, Ken and I are considering a new circuit board that would include our Option Bypass Headers and Internal Mic Adaptor products. I'm guessing the retail price for the pair of kits would be in the $60 to $80 range. (We would not offer the kits for sale individually.) Please email me at webmaster .. @ .. unpcbs .. dot .. com if you are interested. If the response is promising, I'll add an automated pre-order waiting list page to our website. Note that we would require your advance payment, before committing to production. 73, Gary KI4GGX webmaster http://www.unpcbs.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 Message delivered to arch...@mail-archive.com

[Elecraft] [K3] 700 Hz Filters Are Back in Stock!
To order, please visit http://www.unpcbs.com/backdoor/ This is our first batch since INRAD changed hands last October. Most of them have already been spoken for, so they'll likely sell out fairly quickly. There's typically a 14-week manufacturing lead-time -- so if we choose to commission a subsequent production run -- the earliest a next batch could possibly arrive would be in the August-September timeframe. 73, Gary KI4GGX (webmaster) __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] [K3] 8 or 5 Pole cw filters
K8XF writes ... As a cw opr ... I would like to know ... Hi Mike, 1) If you are considering using the optional sub-RX for diversity reception, then you might prefer INRAD's 8-pole filters simply because they are already matched, i.e. their center frequencies are much tighter than Elecraft's 5-pole filters. (We're talking about tens of Hz for the INRAD filters compare to more like a kHz for the Elecraft filters!) 2) All SSB, CW, and digital TX is done via the normal SSB filter (either 2.8 kHz 8-pole or 2.7 kHz 5-pole). Thus many guys will choose the 8-pole 2.8 kHz filter, that it might produce a slightly cleaner transmitted CW signal. This is more important if you run 500 Watts as opposed to 10 Watts. 3) Due to the K3's architecture, it is sometimes desirable to have a crystal filter whose width is close to your DSP passband setting. Specifically when working a weak signal that's close to a strong one. Otherwise, if the strong signal is inside the passband of your crystal filter, it can cause AGC pumping and render the weak signal unreadable. Your needs in this regard will depend on local band conditions. 4) INRAD's 250 Hz filter is actually closer to 370 Hz wide at 6 dB down, while their 400 Hz filter is about 435 Hz wide. That's a difference of roughly 21%, which IMHO is too similar to justify installing both. 5) In addition to the INRAD CW filters offered by Elecraft (1000 Hz, 400 Hz, and 250 Hz), INRAD also offers 500 Hz via their website. See http://www.inrad.net/home.php?cat=140 6) In addition to the INRAD CW filters offered by Elecraft and INRAD, WB2ART and I also offer 700 Hz. Note that this is a special order item which is currently in stock, but which usually entails a preorder waiting list and a 14-week manufacturing lead-time. See http://www.unpcbs.com 7) I suspect that guys who have the P3 (panadapter) tend to set a tighter passband and in turn prefer narrower crystal filters. 73, Gary KI4GGX webmaster, unpcbs.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 Message delivered to arch...@mail-archive.com

[Elecraft] [KX3] Specmanship ... making claims that have no basis in reality; hype.
After several months of preparation, Adrian Ryan (5B4AIY) recently conducted a head-to-head engineering evaluation of several aftermarket KX3 heatsinks. His findings dispelled the long-running best-performing claim of the PAE heatsink as unfounded, yet this claim is still being made by the PAE website! What's more, now there's a second measureable claim The PAE-Kx31 offers the best performance value in any aftermarket KX3 heatsink, delivering more cooling per $ than all others. which probably isn't true either, although there's no way to know for sure based on the scant evidence presented. And given PAE's (zero of one) track record thus far regarding the validity of its measureable claims, the chances of this latest one actually being true are at best 50-50. (BTW, I know of one KX3 owner -- who prefers to remain anonymous -- who needed to upgrade from the PAE heatsink to a Cooler KX(TM) heatsink. Thus, even if this new best performance value claim happens to be true, that fact won't console KX3 owners who find that the PAE heatsink fails to keep their radio from overheating!) Curiously, the only corroborating evidence for this newest claim is an impressive looking graph -- see http://goo.gl/6Zr4gW -- which appears to have been derived from Adrian's test results using a methodology that can best be described as a concoction of hand-picked data, analytical fallacy, smoke, and mirrors. It certainly is interesting that PAE can make this new claim based on Adrian's findings, while continuing to make their original best-performing claim, which the same findings have since discredited. Additional concerns about the validity of this newest claim include: 1) Cooler KX(TM) heatsinks are offered in three grades of finish (raw, undercoated, and painted) to best serve KX3 owners interested in getting the best performance for their dollar, as well as for anyone who wants to operate in direct sunlight or prefers to paint their heatsink some other color. The raw Lite model costs 23 percent less than the painted Lite model, while the raw Plus model costs 30 percent less than the painted Plus model; yet PAE has conveniently excluded the raw and undercoated finish options! 2) No shipping costs or calculations are cited, only mysterious final results. Furthermore, there are numerous international shipping choices and the cost of international shipping varies by country. 3) Although they are repeatable, Adrian's test results don't come anywhere close to quantifying heatsink performance. To use his findings as a basis for any kind of measureable claim is wrong beyond comprehension! --- - - - --- --- - - - --- With regard to the comment We see now why they changed the testing goals. ... the reality is that Adrian's (purely qualitative) test results do not support the kind of presentation that was envisioned.

On Tue Sep 2 2014 at 13:19:20 EDT, Al Lorona (W6LX) posted ... Here's a dumb question ... does 1° deg C. really matter? --- - - - --- Al, On the contrary, you've asked an excellent although slightly ambiguous question. Are you referring to the one degree C difference between the top three heatsinks, or are you referring to the roughly 1 degree C difference between the factory heatsink and the heatsink that came in last place? FYI, the purpose of this testing was primarily to determine how the various offerings compared to one another. In addition, Adrian didn't want to unnecessarily overstress his PAs in the process. Had he chosen higher power levels, then the separation between each of the candidates would have been greater. In fact, it very well might have been possible to break the tie for second place. Keep in mind that this testing was particularly challenging due to the KX3 firmware's 1 degree C displayed temperature resolution. BTW, I know that the PAs generated 8.5 Watts of waste heat running 5 Watts out on 20 meters, and I used a polynomial approximation to estimate that they generated 9.3 Watts of waste heat while running 0.5 Watts out on 6 meters! (No, that's not a typo!) 73, Gary KI4GGX webmaster http://www.ve7fmn.ca/ P.S.

Re: [Elecraft] [KX3] A Comparative Performance Assessment (of Aftermarket KX3 Heatsinks)
Dennis (KD7CAC) recently posted ... I find it curious that there was no mention ... of what surface coating or surface finishing process the tested heat sinks had been subjected to. ... I'm also curious if Fred's lower cost version is still the original size ... --- - - - --- Hi Dennis, The details regarding finish were omitted from his report for the sake of brevity. In fact, Adrian evaluated four Cooler KX(TM) configurations, one each painted and unpainted Lite and Plus model. The reason this information wasn't included, is that the coating had no discernable impact on performance. Addressing your questions about size ... Fred offers two models: his original (Lite) model is 1.25 inches deep and his newer Plus model (which was introduced back in April as Tropical) was originally 1.5 deep. However, in July he increased its depth by 7% to 1.59 inches. And yes, Fred's Matte Black finish is electrostatically applied / heat cured power coat paint, although the entire bottom (heat transfer) surface is unpainted. Fred also offers two choices of unpainted finish: a premium Clear Chromate Conversion undercoat; and raw aluminum (straight from the mill). 73, Gary KI4GGX webmaster http://www.ve7fmn.ca/ P.S. I encouraged Fred to rebrand his Tropical model as Plus, after one reviewer (on the eHam website) seemed to imply that the heatsink could be operated in direct sunlight without concern. Intuition suggests that an unpainted finish would be preferable for operating under intense tropical sun, although even that should be avoided (IMHO). __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] [KX3] A Comparative Performance Assessment (of Aftermarket KX3 Heatsinks)
Don (W3FPR) recently wrote ... why does still air have to be in quotes? Hi Don, That was done so the wording in still air wouldn't seem like a grammatical error. More importantly, here's an excerpt from a recent email from Adrian, addressing your inquiry regarding ambient temperature: The ambient temperature was constantly monitored on the test bench by the transceiver using a very sensitive aviation anemometer. This instrument can measure airflow down to fractions of a knot, and does so by monitoring temperature changes of a heated thermistor, as well as using a ducted fan whose speed is measured via a pulse-counting technique for higher speeds. I managed to keep the ambient temperature stable throughout the test to within an indicated 0.5 degree C, so I was quite pleased with the actual test results. --- - - - --- I certainly could have included details like this in the final report, but tried to avoid providing too much information, and also tried to limit the document to two pages without resorting to a tiny font. More importantly, IMHO Adrian's test environment and methodology were sufficient for his intended objective, which was to compare the performance of the various aftermarket offerings to one another, for the purpose of ranking them. Yes, higher resolution temperature measurements would have made the results more meaningful; but that evaluation is left as an exercise for the reader. BTW, check out http://www.ve7fmn.ca/faqs/#about_testing for a description and photo of the setup Adrian had used for his original comparison of the factory/stock heatsink and his Cooler KX(TM) Lite, which used an entirely different methodology. 73, Gary KI4GGX webmaster http://www.ve7fmn.ca/ __ 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 Message delivered to arch...@mail-archive.com

An independent head-to-head thermal performance evaluation of several aftermarket KX3 heatsinks was recently concluded by Adrian Ryan (5B4AIY), who holds degrees in Electrical Engineering and Mechanical Engineering. The clear winner of his testing is the Cooler KX PlusT, which is produced by VE7FMN of Simply Better Manufacturing!

[Elecraft] [KX3] What Your Dollar Actually Buys You -- was JT/heatsinks
Yesterday, WA4PSC wrote ... increased key-down time at 12 watts is a nice bonus for digital modes. --- - - - --- Recently I've been helping to facilitate the independent performance evaluation of several of the aftermarket KX3 heatsinks mentioned here over the past few months. The quantitative results of this evaluation (which will be published in a few weeks) will enable KX3 owners to separate fact from hype, and compare the various offerings based on the ratio of their performance versus their cost. Elaborating ... you might want to know what your dollar buys you in terms of heat dissipation. For example, if two competing products differ in price by a factor of 2X, but their performance differs by a factor of 4X, then the more expensive heatsink might be your better choice since it offers 2X greater performance per dollar! Note that the performance versus cost ratio doesn't tell the whole story, since you might not need the additional 2X performance benefit the more expensive heatsink provides. Even so, you still might be able to justify the additional cost based on the extended product life that's anticipated because of the additional cooling capacity!

[Elecraft] Apology
Sorry for my previous post. I thought it was an off Reflector reply directly to VE7FMN.

This is an especially small batch as our aim is to squeeze in yet another production run in time for the December holiday buying season.

As a result, this production run will probably sell out by July. 3) The reason we are requesting so few extra filters, is that we want to squeeze in another production run before the (winter solstice) holiday shopping season. 4) Our long-term plan has that subsequent run arriving the 2nd or 3rd week of November. Most likely it will be the last run of 2014.

Re: [Elecraft] Are filters bought from Inrad the same as filters bought from Elecraft ?
A couple hours ago Larry Lopez (N2CVS) wrote ... Does Elecraft test the incoming INRAD crystals? Elecraft designed and produced a small gadget and provided it to INRAD at no charge. This gadget accepts one filter at a time, and has a cable to connect it to a network analyzer. With this setup, INRAD is able to test their K3 filters in-house, to ensure they meet Elecraft's specifications, (which I suspect includes a maximum center-frequency offset for each bandwidth). Elecraft's post-production processing of 8-pole INRAD filters is likely limited to applying their label and adding the necessary mounting hardware.

[Elecraft] [K3] Perfect for Field Day SP ... Limited Production 700 Hz 8-Pole Filters
Unless you have a panadapter, you'll never work weak stations, if you can't hear them because they're outside your passband! (This is the beauty of 700 Hz!) In fact, many seasoned Elecraft K3 owners feel that using the radio's 400 Hz default (NORM) CW passband setting, is kind of like viewing the world thru a drinking straw while riding a bicycle. That is, it would be fairly easy to skip right past a weak calling station, without ever realizing it was there. But even more importantly, prolonged scanning with a 400 Hz passband can be tedious and fatiguing. This is why, band conditions permitting, savvy operators prefer a 700 Hz passband: o for general CW tuning -- W3FPR o for scanning the band (or a pileup). -- K8GU o for combing through the pileups with VFO [B] -- NI0C o to cruise the CW bands from a wider perspective -- N1LQ --- - - - --- The next batch is due to arrive May 16th. Demand for these custom filters can fluctuate dramatically, so it's impossible to say precisely when this next manufacturing lot might sell out. (Our best guess is: April 1st, give or take a few weeks.) A subsequent production run can be expected about 15 weeks thereafter. If you have a sub-receiver or you are considering getting one, then FYI the center frequency offset of individual manufacturing lots, can vary by up to plus or minus 100 Hz. In contrast, the variation across any given lot is typically only plus or minus 5 Hz; yielding superbly matched pairs for diversity reception! --- - - - --- Visit http://www.unpcbs.com to place an order, and for full details including: o Retail price. o The filter's passband response plot. o User comments. o Special terms of sale. o Bandwidth and availability FAQs. o App notes. o An animated slideshow illustrating all five INRAD CW bandwidths. 73, Gary KI4GGX (webmaster) __ 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] It's Time to Get in on the Next Batch of Custom Order 700 Hz Filters
WB2ART and I are currently accepting formal/paid orders against the next production run of 700 Hz 8-pole INRAD filters for the K3. The cutoff – to guarantee that you get in on this next batch – is 1200 UTC on Tuesday January 28th, at which time we will commission INRAD to initiate production. Assuming a 15 week lead-time, we expect to receive the filters on Friday May 16th, give or take a week. As always, we will order a few extra filters based on our best guess of how many additional requests we might receive by the date the filters are expected to arrive. But please note that demand for these filters can vary significantly, so it's entirely possible the batch will completely sell out, even before the end of February! Further, if you miss out on this upcoming batch, it's most unlikely you'll be able to obtain a 700 Hz filter in time for Field Day. That is, unless you can find someone who is willing to part with theirs. Please visit http://www.unpcbs.com to place your order and for full details including: price; passband plot; user comments; FAQs; app notes; and a nifty visual comparison (slideshow) of all five INRAD CW filters. I especially suggest that you check out the (recently updated) What Others Have Said section, at http://www.unpcbs.com/filter/#comments 73, Gary KI4GGX (webmaster) P.S. Eric, please forgive me for this, my third 700 Hz (commercial) post in the past two weeks. __ 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] Never Say Never ... was The End is Here
It seems there's still a demand for our custom order 700 Hz 8-pole K3 filters. In fact, we've already started a waiting list for the next batch, and hope to commit to production -- possibly within a week, but if not, then preferably no later than the end of January. That would see the filters arriving sometime in May; so certainly in plenty of time for Field Day. The only catch is that Ken prefers we have at least five preorders before we move forward. So, if you want another production run happen, you can help make it a reality by registering via our automated waiting-list webpage at http://www.unpcbs.com/list/ Please visit http://www.unpcbs.com/ for full details, or email me off-list with your questions, suggestions, etc. MNY TNX 73, Gary KI4GGX (webmaster) __ 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] 700 Hz 8-Pole K3 Filters Last Time Buy?
Interest in our customer-order 700 Hz K3 filter (by INRAD) has fall off dramatically since Field Day, leading Ken and I to wonder whether everyone who wanted one has already gotten theirs. Thus, depending on future demand, there might not be a last-time-buy opportunity to get one of these limited-production filters. However, even if there isn't another production run, we were able to procure a few production overrun units from INRAD. These remaining filters are available now while they last. Once they are gone we will start a waiting list to determine whether or not there will even be a next production run.

[Elecraft] Custom 700 Hz 8-Pole K3 Filter Availability
Batch #5 (which arrived about a month ago) is just about sold out. Sales of these limited production filters have been fairly slow since mid-summer, but we expect they'll pick up as the holidays approach. Once this batch sells out there will be at least a 15-week lead-time (12 weeks manufacturing + 3 weeks transit and processing) until batch #6 can be expected to arrive at your QTH. So we are probably looking at the March-April timeframe, although the exact date will depend on how quickly the current batch sells out.

Re: [Elecraft] K-2 observation
Moments ago Don (W3FPR) wrote ... ... you might try re-flowing the solder on the Front Panel board with a hot iron (750 degF) and add just a touch of solder - actually all you need is the flux. -- Vern, Just to emphasize what Don means, you should NEVER REHEAT/REFLOW A SOLDER JOINT WITHOUT ADDING SOME FRESH FLUX as this will result in a very poor and very unreliable solder joint. And a flux pen is a better source than using additional solder, because you don't want too much solder. Yes, solder can be used as a source of fresh flux in a pinch -- in the absence of a flux pen -- but you might first want to remove some of the existing solder. Elaborating a bit further, a blob of solder on the tip of your iron isn't a solution, as the flux would have already burned off by that point. Instead, Don is suggesting that the solder would need to be feed directly into the joint once it's hot. If you have to resort to reheating every joint on the Front Panel, then I suggest a flux pen (or other similar flux dispenser) is a must! 73, Gary KI4GGX __ 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 Roofing filters
On Tuesday August 6, Ivan (G3IZD) wrote ... I am about to purchase a K3 ... what is the general feeling regarding [filter] bandwidth(s) ... -- Hi Ivan, In addition to the choices available from Elecraft and INRAD, WB2ART and I also offer a 700 Hz (wide CW) alternative. IMHO 700 Hz fits really well between the INRAD 1.5 k Hz and 400 Hz filters and it's ideal for scanning. The lead-time for the 700 Hz filter is upwards of 14 weeks, as there's a 12-manufacturing lead-time and we only commission production as demand warrants. The current batch (due to arrive in early October) will probably sell out within a matter of hours. The next batch can be expected sometime between December and February. --- - - - --- Our website http://www.unpcbs.com/ features a unique visual comparison of the five 8-pole filters (1,000, 700, 500, 400, and 250 Hz). This comparison is packaged as both an online slideshow and as a (printable) PDF file. Brief descriptions accompany each slide. As a whole, these descriptions create a concise 8-pole CW filter buyer's guide If you are a serious contester, then 700 and 400 Hz would be an excellent choice. Otherwise (if you're not a serious contester) then the 700 is probably the only CW filter you'll ever need. Oh and it's also ideal for 500 Hz digital formats. --- - - - --- Additional suggestions ... 1) Avoid filters whose widths are too similar. Specifically, IMHO a ratio of less than 1.4 (i.e. the square root of two) is an exercise in diminishing returns. 2) For historic reasons, the filter widths are not always the same as their designations. This is especially true of the INRAD 250 Hz 8-pole filter, which is closer 370 Hz wide. 3) INRAD offers two additional 8-pole filters 1500 Hz and 500 Hz which are not available through Elecraft. 4) If you have the sub-RX, then adding/changing filters is a fairly significant undertaking. (Thus the advice about just getting a bare K3 and adding filters later may not apply to you, if your intention is to get a factory assembled K3 with sub-RX.)

And perhaps more importantly, you won't run the risk of dissimilar metal corrosion on the internal socket contacts, or the risk of installing these parts in the wrong place.

[Elecraft] [K3] Custom 700 Hz 8-Pole Filters
The next batch of 700 Hz filters is due to arrive this week! Ken and I are pleased to announce that -- for the first time -- these filters will be available from stock while supplies last. Depending on demand, they'll probably sell out sometime between Dayton and Field Day. We cannot yet say whether or not there will be a subsequent batch. Although even if there is, it most likely wouldn't arrive until 2014. Due to their limited production volume, these custom filters retail for $145 plus our default SH charge. (The $5 surcharge -- over Elecraft's 8-pole filter price -- covers the cost of shipping the batch from INRAD and the cost to insure your individual order.)

I can offer a few thoughts for you to consider, but before I do ... if you were to build a K2, then I suggest that you purchase a Rework Eliminator(TM) K2 Option Bypass Headers kit, and perhaps also a Rework Eliminator(TM) Internal Mic Adaptor. See http://www.unpcbs.com/ for details. --- - - - --- Now then, some factors to consider in your decision making process might be ... 1) Do you prefer the latest technology which will continue to develop for years to come via firmware upgrades? Or the nostalgia of through-hole construction? 2) A pro for the K2 is the building experience plus the fact that you can repair and upgrade it yourself. (BTW, this is where the Rework Eliminator(TM) Headers are worth their weight in gold!) 3) Pros for the KX3 are no doubt functionality, features, portability, and probably also value, including resale value. (I'm guessing the two radios are probably about even with regard to RX power consumption.) 4) As far the value of the K2 is concerned, the bare kit is still a bargain; whereas a fully loaded K2 is difficult to justify. UNLESS the building experience is one of your most important criteria! 5) One last thing to consider is that the KX3 will certainly be around for many years to come, whereas your opportunity to purchase a K2 is probably measured in months at this point. 73, Gary KI4GGX K2 #4067 unpcbs.com webmaster P.S.

[Elecraft] [K2] Another Rework Eliminator(TM) Option Bypass Header Production Run
Ken and I have been wondering whether there's sufficient interest to warrant another Headers PCB production run. We would like to offer our K2 Headers kit again, but the steep manufacturing setup charge necessitates a minimum order quantity of at least 75 pieces.

We are currently accepting preorders to gauge the level of demand. If you are interested in purchasing one of our K2 Headers kits, please visit our website, http://www.unpcbs.com/ for details on how to submit your preorder online; as opposed to emailing us directly. (The number of preorders we need is more than we're prepared to manage via email.)

[Elecraft] [K3] Interest in Custom 700 Hz 8-pole INRAD Filters?
Given the lack of response to N8CEP's recent WTB Reflector message, we are curious if there's sufficient interest to warrant another production run. FYI, although 700 Hz was originally requested by CW ops who felt that 1000 Hz was too wide and 500 Hz too narrow, digital mode enthusiasts have since discovered that 700 Hz is also ideal for some of the newer 500 Hz modes. Assuming a manufacturing lead-time of 13 weeks, the next batch should arrive in plenty of time for Field Day. Provided that is, that we can spread the word fast enough to reach our minimum order target of 20 pieces by the end of February. (Presently we're at 2, so we need 18 more.) Please email us at support@unpcbs.com to get in on this next batch. (We call that placing a pre-order.) Or, visit http://www.unpcbs.com/ to learn more, including how to follow this topic on Facebook. 73, Gary KI4GGX Webmaster __ 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] What Exactly do You Receive (was When you order)
At 23:08 EST on 6 Mar 2008, RC Conley (KC6WA) wrote ... ... what exactly do you receive when you order a basic K3/10 ...? -- Hi RC, You are actually asking two questions: 1) What hardware do you get? 2) What functionality does the firmware provide? A good place to find a high-level answer to the hardware question is to visit Elecraft's ordering webpage ... http://www.elecraft.com/elecraft_prod_list.htm#k3 ... and simply observe what optional modules are available. Very briefly, the hardware that doesn't come with the base K3 includes: o ATU module o Sub-Receiver (which includes a second identical RX plus a second DSP) o 100 W PA module o Ten optional roofing filters (the base K3 includes a 5-pole 2.7 kHz filter; both the main and sub-RX can each hold five roofing filters) o General Coverage BPF module (both the main RX and the sub RX can accept one) o Transverter Interface With RX Antenna I/O module o An optional five times higher accuracy TXCO o Digital Voice Recorder (will eventually have firmware support for vision impaired operators) Another excellent way to appreciate what hardware you get is to read the K3 assembly manual. See ... http://elecraft.com/manual/K3%20Assembly%20Manual%20Rev%20D%20Web.pdf --- - - - --- The answer to the functionality question is a moving target since Wayne continues to add features to the firmware. As I don't yet have my K3, I'm not in a position to provide details on this subject. BTW, an excellent resource describing the current firmware functionality is the product review that will appear in the April issue of QST. You can see it now on Elecraft's website at ... http://www.elecraft.com/K3/K3%20QST%20prod%20rev%201.pdf A second resource is the K2 operators manual.
