It was something I suggested and turned out to be very affective. It wasn't really physical a button. It was actually an on screen control that passed a parameter to the Hamblaster telling the LMS algorithm to stop up dating. The LMS algorithm converged on the carrier and then stopped updating it's coefficients . It locked the auto-notch frequency and killed the carrier without affecting the voice. The Idea was to have a semi-automatic filter that you can press a button, quickly notch the carrier and lock the null frequency and depth. A manual adjustable notch was too cumbersome and would required fiddling with the frequency adjustment knob while trying to null the carrier. I would love to see this feature added to the K3.

The output impedance (source impedance) is NOT necessarily the same as the rated Load impedance. Rather, the rated Load Z is the Z that the output stage is happy driving based on its dynamic characteristics (what we old farts, raised on hollow state devices called the "Load Line"), and will often be LESS THAN the rated Load Z. Yes, the matching network should be tuning out the reactance, and it should be providing the resistive load Z that the rig wants to see, but this Z will rarely be the source Z of the output stage, and will often be much lower. But the real question here is, why expect a transceiver, designed nearly 20 years ago, to be suitable for measuring the impedance at the transmitter end of a piece of coax connected to an antenna when so many EXCELLENT devices capable of that measurement are available at remarkably low cost, and with great power and flexibility? There are the AIM products, OK but expensive for what you get, and my favorite, the German designed, UK built, VNWA, a 1.5 GHz Vector Network Analyzer that cost me $750 delivered to my home in W6 three years ago with calibration loads. I export data from this unit in Touchstone format (a plain text format for data exchange) to SimSmith (freeeware, excellent) and let it compute the complex Z at the antenna end of the coax, having measured the length of the coax using the TDR capability of the VNWA. I can also expert data from the VNWA on this sort of measurement to AC6LA's excellent Excel spreadsheets, and also the data on a sample length of any piece of transmission line (coax or other) to compute fundamental properties of the transmission line. I can also use SimSmith to design matching networks using stubs and discrete components. http://k9yc.com/PacificonSmithChart.pdf So with all of this analytic capability with very good accuracy available at very low cost, why would you want to use a K2 and far less elegant methods to do much less? 73, Jim K9YC On 7/31/2014 6:32 PM, Don Wilhelm wrote: > what the conjugate match says is that if you cut a transmission line > at any point, looking one way at that cut point, you will have some > impedance - example is 70 + j20.

That will cancel the tone with no other effect on the signal. That ain't easy, because it must track the drift of both the TX and the RX and the varying strength of the interfering signal, but with DSP, it IS possible. The beauty of this technique is that it has NO effect on the desired signal -- it simply cancels the interfering carrier. The alternative technique is to add a narrow band notch filter, which MUST add phase shift that distorts the audio. The deeper the notch and the narrower the filter, the greater the phase shift, and thus greater distortion of the signal. These are fundamental concepts -- as my friends back home used to say, "you cain't get no better" than this, :) and you must be very good (and have the processor cycles available) to do it well. 73, Jim K9YC From gm3sek at ifwtech.co.uk Fri Aug 1 05:06:28 2014 From: gm3sek at ifwtech.co.uk (Ian White) Date: Fri, 1 Aug 2014 10:06:28 +0100 Subject: [Elecraft] [K3] Manual Notch Reconsidered In-Reply-To: <53DB4BA4.7040008@audiosystemsgroup.com> References: <006301cfad46$f15db540$d4191fc0$@windstream.net> <53DB4BA4.7040008@audiosystemsgroup.com> Message-ID: <004401cfad67$e63ba8e0$b2b2faa0$@co.uk> For both manual and auto notch, the key seems to be to create two identical streams of signal data and apply different DSP to each. Stream 1 is totally focused on extracting accurate information about the interfering tones (frequency, amplitude, phase) regardless of any damage it may do to the audio signal. The damaged audio signal from Stream 1 is then thrown away. Instead, the tone information extracted from Stream 1 is applied very carefully to a 'clean copy' of the same data in Stream 2 to cancel the interference with minimal damage to the recovered audio. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Jim Brown >Sent: 01 August 2014 09:11 >To: elecraft at mailman.qth.net >Subject: Re: [Elecraft] [K3] Manual Notch Reconsidered > >I have no clue what the K3 does, but the slickest way to do this is to >first sense the frequency of the tone you want to notch, then create a >tone of the same frequency, shift its phase so that it is exactly 180 >degrees out of phase with the interfering tone, make it equal to the >interfering tone's amplitude, and add it to the signal.

The power transfer theorem isn't useful in most real world cases. In practice, the optimum load for a PA will be very different from its AC resistance (the reactive part should be corrected for by the fixed part of the output matching circuitry). For an AF PA the AC resistance will generally be much lower than the optimum load line resistance, because of the heavy feedback used. For RF PA's there will be lots of parasitic impedances and relatively little, if any, feedback will be applied, so the situation is more complex. Without feedback, I have a feeling the resistive component will be high, as it would be at AF, without feedback, but I've not looked into the details. (The K2 low power PA does have some negative feedback, so it is possible that it acts as a voltage source, i.e. has an AC resistance much lower than optimum load.) Generally, however, the optimum load is determined much more by the target output power and the available power supply voltage. To a first approximation, for ideal class B push pull, you want Vcc**2/RL to be twice(?) the PEP. You then transform 50 ohms to that optimum value, which is probably reactive, with the fixed part of the matching network. It is the 50 ohm design value for the load that the KATn matches to the antenna, not the actual source impedance of the transmitter. If you look towards the transmitter, you will not see the complex conjugate of the feedline input impedance, however, if you assume 50 ohms and the ATU L and C values, you will get the complex conjugate of the feedline input impedance. -- David Woolley Owner K2 06123 On 01/08/14 00:32, Per-Tore Aasestrand wrote: > > On 1 August 2014 01:16, Don Wilhelm wrote: > > If one uses the voltage divider example, yes the maximum efficiency is 50%, >> But the output of a PA stage is not a resistor, and the collector load >> "resistance" is set by the designer to produce the output power desired. >> > > I fully agree. > > But will not a conjugate match also imply a max efficiency of 50% From forums at david-woolley.me.uk Fri Aug 1 05:48:18 2014 From: forums at david-woolley.me.uk (David Woolley) Date: Fri, 01 Aug 2014 10:48:18 +0100 Subject: [Elecraft] Auto Notch Revisited.

That does, have the disadvantage that if the tone is really external and than goes away, the cancelling tone remains for a while and you actually get an interfering signal as an artifact. That would mean that it would not work well for modulated tones, e.g. morse signals, rather than pure carriers. I don't really understand all the references to least squares. Least squares is basically about the simplest way of matching parameters of an expected signal to an actual signal in noise. What is interesting is the choice of parameters being fitted, and the expected form of the signa, not that there is a least squares fit. If what is really being described here is to do a least squares fit of a sine wave and then add the inverted version of this, that would work better than an automated notch filter for continuous carriers (essentially because it would be extremely narrow bandwidth, much narrower than could be achieved with acceptable group delays with a filter), and would not impact on speech, but would not work at all well for modulated carriers (effectively its bandwidth is much lower than that of a morse signal). Incidentally, the real research funding for noise reduction of speech is in the hearing aid industry - that's essentially what modern digital aids are about. People with moderate to severe through profound loss often complain about the artefacts produced by the noise reduction and speech compression. People with profound loss, who have previously used analogue aids, often have difficulty moving to digital aids because they can't get used to the artefacts. -- David Woolley Owner K2 06123 On 31/07/14 22:01, wa9fvp wrote: > Back in the early 90's I worked with another Engineer on a project we called > "The Hamblaster".

The Dept of Veterans' Affairs gives me hearing aids, replacing them every 5 or so years [Thank you US Taxpayers, you change my life!]. They are quite amazing, mine are Phonak. They will "notch out" the siren on a fire truck. They don't take it all the way out [sort of unsafe not to hear it at all], they do it almost instantly over some threshold amplitude, and the "notch" follows the pitch of the siren. I suspect they are doing what Jim, K9YC, suggested in another email on this thread. They have 5 different automatic "programs" for differing circumstances. One is for music which they somehow recognize after about 3-5 seconds. They will also suppress the wind noise in my truck in about 3-5 seconds. I think that suppression is just a roll-off of the very high frequencies. I rarely use the manual notch on CW. I'm not on SSB very much but when I am and in a non-contest environment, I have used the auto-notch and I don't discern any artifacts from the K3. On some bands, I use the NB all the time on CW, it *does* knock down some repetitive components in the power line hash. I don't notice any artifacts, but I can create them with very aggressive settings. NR makes SSB signals sound a bit strange and I rarely use it. Incidentally, my hearing aids seem to have Bluetooth because they "talk to each other," apparently negotiating when to change programs. They do all of this on 1.4 V from batteries about the size of a 10-32 nut. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 8/1/2014 2:48 AM, David Woolley wrote: > Whilst summing the inverted NR output doesn't sound logically any > different from applying a custom filter, the tactic used by hearing aids > (at least Oticon ones) is actually to determine the frequency and phase > of the presumed interfering signal (howl round in that case) and add in > an inverted version. > > That does, have the disadvantage that if the tone is really external and > than goes away, the cancelling tone remains for a while and you actually > get an interfering signal as an artifact.

Its clear now; there is Y-splitters which are not OK for K3 usage as all 15pins should be wired 1:1, and this not the case with all VGA Y-splitters. Good thing is that there is also available those which are OK, but should be checked first that they are 1:1 whith each of the pins. Also one good product is the "breakout board", which could be esily wired for diffrent purposes. I think I will get one Y-splitter and also breakout-board for test purposes. 73 de jukka - OH2MA 21:12, Joe Subich, W4TV kirjoitti: > > The K3 requires all 15 pins be wired through and none connected > together.

Noise level about an S5 to 7. I was using DM780 and the WinKeyer option for sending as my fist is not good due to arthritis. When I looked up at the decode screen on DM780 it was doing a very good job. So I began to play with the settings for bandwidth and squelch and it was doing a really good job. After reading some of the comments lately on the K3 CW decoder, I decided I would do some playing with it as well. YR10RRO was gone but ZF35LC was there and I am pleased to say, the K3 was doing a good job as well. So again I began to play with the available settings and by adjusting the threshold and bandwith, I found it to do a really good job. All of the above was done with slow AGC. I suspect further improvement would be possible by running with AGC off and reducing the RF gain to improve the S/N ratio. Like virtually all of the decoders I have tried from CWGET on to the present, it takes a character or two for the software to "lock on". After that, the results were very good. I probably would give the edge to HRD with DM780, but the K3 was hanging in there, perfectly acceptable as far as I am concerned were I an CW OP looking for a bit of help. The lineup here is a K-Line with a Navigator interface and I will have to give credit to the Navigator as well for its very low noise CODEC. Just thought some might be interested so thought I would pass it on. 73s Jim, W4ATK From km4ik.ian at gmail.com Sun Aug 3 00:00:59 2014 From: km4ik.ian at gmail.com (Ian - Ham) Date: Sun, 3 Aug 2014 00:00:59 -0400 Subject: [Elecraft] SSB Net Announcement for Sunday, August 3, 2014 Message-ID: <0cc601cfaecf$8995e880$9cc1b980$@gmail.com> The Elecraft SSB net will meet this Sunday, August 3, 2014, at 1800 UTC on 14.3035 +/- QRM.

No doubt the most interesting information is contained in the two plots, which show how TX efficiency varies with frequency and output power. The variations are surprising, and the implications are significant! (As many KX3 owners have already discovered, 0.5 Watts output is a practical limit for high duty cycle TX on 6 meters using the factory heatsink.) 2) The "Remarks" page is now organized by subject matter! --- - - - --- Meanwhile, work continues in other areas: 1) My installation guide PDF file will be available for download in a few weeks.

What mode are you using? If it's CW then there's a problem, if FM, maybe that's too wide a mode to stay within the limits? In Germany I know a couple of Amateurs have licences for 69.950MHz, or a nearby frequency, to transmit and, of course, in the UK we already have 70.000 to 70.500MHz.

Simply put, there's no easy way do connect a P3 to the IC-7600. (If anyone knows of a way, I'd sure like to hear about it.) However, there ARE methods that will provide a much improved panadapter/waterfall display over what shows on the radio's screen. There's an easy mod that uses a Mini-Circuits or other brand, two way splitter to bring out the IF scope signal. You basically pull the coax line from the IF to the scope input on the board inside the radio and insert the Splitter such that one of it's outputs goes to the original scope input connector and the second splitter output goes to the outboard device. Usually a simple "dongle SDR" or LP-Pan is used with a computer program for a much improved panadapeter & waterfall display. Another somewhat more costly way is to use the same splitter between the Rx-IN & RX-OUT connector to drive something like and SDR-IQ or as I am doing, a QS1R SDR receiver running SDRMAX V + Omni-Rig. The SDR basically runs in parallel with the IC-7600 and Omni-Rig allows master/slave functions between them. It's a lot of stuff to turn on, but you'll be rewarded with a spectacular screen of info. 73, Charlie k3ICH ----- Original Message ----- From: To: Sent: Sunday, August 03, 2014 1:22 PM Subject: [Elecraft] P3 > Has anyone hooked the P3 to an Icom IC-7600? > I also have the K3 and would like to share it on the IC-7600 > > 73 > > Arlon Nelson W0TUP > North Dakota > > My designated driver is 12BY7A > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 pincon at erols.com From dave at g0dja.co.uk Sun Aug 3 15:02:03 2014 From: dave at g0dja.co.uk (Dave) Date: Sun, 3 Aug 2014 19:02:03 -0000 Subject: [Elecraft] KX3 4m-Band Bandlimits References: <2121dd416da417c4e064acc88e8f305d@mwinf5d68.me-wanadoo.net> Message-ID: <0D45CF877297432CA641C96382B8AF49@dave633cb49a5b> Many countries have or say that they are allocating frequencies in the 4M band David.

If I understand it, it is the simple algorithm used in (early) modem equalisation filters, because it is cheap to compute. The problem with it in the context of this thread is that it needs a value for d(n). Although d(n) is confusingly defined in the actual article, I believe it represents the "correct" (desired) output of the filter. That is easy in a digital system, where you can determine it by slicing the output of the filter (and possibly running forward error correction), but the context of this thread was the use of the auto-notch on voice signals. In that case, it takes human intelligence to work out the general nature of the correct signal, and even then that doesn't give you the exact waveform. What I guess you must be doing, for voice, is using an expected signal of silence (d(n) = 0) and hoping that the voice signal is sufficiently uncorrelated that the filter fails to converge on to it, but only onto the, simpler, interfering carrier(s). -- David Woolley Owner K2 06123 On 02/08/14 01:39, wa9fvp wrote: > If your interested in some technical stuff, there's a very good tutorial > about the LMS algorithm on the National Instruments web site.

If the purpose is to separate voice from a sinusoid, then one utilizes the fact that a sinusoid has a long correlation function in time compared to voice. If the delay is longer than usual correlation time for voice, one will get a reference for the desired signal - at least in the correlation domain which is what counts here. For a noise reduction filter, the delay is often shorter, as noise has short correlation time compared to a voiced signal.

The application will be 6M JT65 from a rare grid. A key element of that is deciding what battery pack to buy. Because weight is a primary consideration, Li Ion is the clear choice, but the decision is between 3-cell and 4-cell packs. Real data on LiIon battery packs is damn near impossible to find. I've found discharge curves that make sense, but it isn't clear whether the voltages shown are open circuit or under load values. The difference, of course, is the internal resistance, and that's what I'm trying to get a handle on. I'm considering batteries in the 20-25 Ah range, with the Ah rating based on 10A. So my question is, what sort of internal resistance should I expect for a battery rated like this? Yes, I know if I had the battery and a sufficiently accurate voltmeter I could measure it, but these batteries sell in the $250 - $300 range, so I would like to know before I buy. Here's a pack that I'm considering. http://www.batteryspace.com/polymerli-ionboxbattery111v252ah27972wh14arateli-ionwithcarsocketsmartcharger.aspx A 11.1V (3-cell) battery is clearly the right choice to run the KX3, but it's the KXPA100 (100W amp) that I'm concerned about. I suspect that it isn't going to be happy much below about 10.5V. That's OK if the published discharge curves for Li Ion batteries represent the terminal voltage under load -- they show about 90% of capacity with the rated discharge current, but if that voltage is reduced by the internal resistance, I've probably got at least 10% less. The link below shows the discharge curves for a single cell, followed by my own plots of the same data multiplied by 3X and 4X for 3-cell and 4-cell packs. The KX3 and KXPA100 are rated for supply voltage up to 15V, and I've been told that 16V is an absolute maximum. That means the output of a 4-cell pack is too much, so I think it has to be 3 cells. k9yc.com/Lithium Ion Discharge.pdf Can anyone point me to some real data or relate some experience on this? 73, Jim K9YC From elecraft at mailman.qth.net Mon Aug 4 03:05:46 2014 From: elecraft at mailman.qth.net (Harry Yingst via Elecraft) Date: Mon, 4 Aug 2014 00:05:46 -0700 Subject: [Elecraft] K3 won't power up In-Reply-To: <822a9aecfc2c438f8ed4936ab0400dc1@Server.thorntonmostullaw.com> References: <822a9aecfc2c438f8ed4936ab0400dc1@Server.thorntonmostullaw.com> Message-ID: <1407135946.14756.YahooMailNeo@web125906.mail.ne1.yahoo.com> I would look for the missing nut first (possibly stuck to the speaker) Then I'd take the top and bottom covers of and check traces etc ________________________________ From: George Thornton To: Bruce Beford ; "elecraft at mailman.qth.net" Sent: Sunday, August 3, 2014 10:51 PM Subject: Re: [Elecraft] K3 won't power up I have a k3 that was working fine but now will? not power up.

The voltage from the pack is either too low (3-cell) or too high (4-cell), and they are quite dangerous if physically abused. Instead I would go with 4-cell LiFePO4, another form of Lithium battery. The iron stabilizes the lithium, and at no part of the discharge or charge process is there any free metallic Lithium in the cell (that's what makes traditional Li-ion so dangerous - Lithium burns violently when exposed to water, even moisture in the air). The energy density of LiFePO4 is almost as good as a traditional Li-Ion. Check out the LiFePO4 batteries offered by BioennoPower.com I have plenty of information and discharge curves for various LiFePO4 batteries on my website, www.wb4son.com For example, check out a discussion of a 30 AH battery here: http://wb4son.com/wpblog/?p=1250 As for your specific question, you can expect almost any LiFePO4 batter to remain above 13 volts under load for about 80% of its capacity. It will start about 14.3 volts (open circuit), and won't drop below 13.0 volts for a long time. You will need to figure out your desired capacity, and also make sure you select a battery that will support the maximum current you need. I've run IOTA operations for a weekend (30 AH), and ran our GOTA station for Field Day off of LiFePO4 batteries (60 AH).

For lead acid, it's typically at C/20h and then higher rates. A plot showing open-circuit voltage after some amount of usage should be labeled "stage of charge" rather than "discharge". In the case of the plots in your PDF, the first plot shows three lines, with 0.2C, 0.5C and 1.0C. This is sloppy, because C is in Ah, and 1.0C therefore has units of Ah, which makes no sense. But surely that means C/1h and is in amps. 0.2C is C/5h or 0.2 1/h * C. And I see this all the time; the RC people know what it means :-) It's interesting that the curves are so close, for 0.2C and 1.0C. As I read it, there's only a few % (from 100 to 95 at 3.2V cutoff) loss. For lead acid, there would be a far greater difference at these rates. For JT65, what power output are you running, and what input voltage is needed for the KXPA100 to be happy? I would think you'd be down around 50W for linearity and heat, but I don't yet have any JT65 experience. It's unfortunate that equipment designed around lead acid batteries (our nominal 13.8V notion) wants the first half of a 3S pack and the second half of a 4S. I don't think this is useful, but you could consider different batteries for the kx3 and kxpa100. But with the same max, the kx3 should be fine with what the amp needs. I find "25 Ah at 10A" to be unusual, but I think it's the difference between lead acid standby/cycle use, where capacities are ~always given in 20h rate, and LiPoly RC culture, where the 1h rate is a slow discharge. I wonder if 10A is a standard discharge current for multiple batteries - it's a fair metric if the question is "how long can I power a 10A load". Have you thought about DC-DC converters? I am about to order an AnyVolt3, which isn't big enough (3A) to power a KXPA100. But a converter could dodge the max/min issue, and may be worth it in weight/price, presuming it's quiet (which some are said to be). 73 de n1dam From bob at hogbytes.com Mon Aug 4 09:02:42 2014 From: bob at hogbytes.com (Bob N3MNT) Date: Mon, 4 Aug 2014 06:02:42 -0700 (PDT) Subject: [Elecraft] Internal Impedance of Li-Ion Battery Packs In-Reply-To: References: <53DF21BB.3080900@audiosystemsgroup.com> Message-ID: <1407157362754-7591907.post@n2.nabble.com> Another *KEY* consideration, especially since you indicate it is a rare DX location ( I read as air travel required) is what you will be allowed to take on the plane.

There isn't a good "standard" for what the capacity is based on. You need to check with each vendor. LiFePO4 batteries are very Coulomb-efficient -- what goes in is what goes out, and this tends to keep your capacity very close to rated values no matter what the load is. It also means that unlike SLA batteries, a LiFePO4 doesn't get hot charging or discharging (at least not at 20 Amp values) -- this is because the internal resistance is so darned low -- so there is little wasted energy in a charge/discharge cycle. My Bioennno 30 AH rated battery, tested at C/4 rate of 7.5 amps (the limit of my test equipment), provided me with 29.88 AH of usable capacity, and that was stopping the test at 12.00 volts, which is several volts higher than absolute minimum (8.8 volts). Speaking of which, I would highly recommend you stop using your battery when the terminal voltage falls below 12.00 volts -- there will be very little remaining capacity at that point anyway. http://www.bioennopower.com/collections/12v-series-lifepo4-batteries/products/12v-20ah-lifepo4-battery That 7 pound battery is $198 including the charger, and will outperform a 40 AH SLA battery (will last 5 to 10 times longer, will weigh 1/5th as much). 73, Bob, WB4SON On Mon, Aug 4, 2014 at 9:02 AM, Bob N3MNT wrote: > Another *KEY* consideration, especially since you indicate it is a rare DX > location ( I read as air travel required) is what you will be allowed to > take on the plane.

So it will not power up if the power leads are reversed - and normally will recover with no damage when that condition is corrected. The KPA3 is not similarly protected - the diode drop would be too large and a 20 amp diode would be required. The PA depends on the circuit breaker. The one element that is not protected is the RFC in series with the DC input - RFC6. If the power were reversed, it is likely that RFC6 could have opened before the KPA3 circuit breaker tripped - the reaction of the users in the field would be to reset the breaker, so when it returned, the breaker would look OK. A bit of investigation with an ohmmeter following the path from 12V In on the K3 schematic (RF Board sheet 3) will verify whether power can get to the cathode of D6. Speculation on my part, but I would investigate based on that scenario. I doubt the loose nut has anything to do with the problem, but does need to be corrected. 73, Don W3FPR On 8/4/2014 9:49 AM, Mike K2MK wrote: > Hi George, > > A working K3 didn't power up at field day.

The consensus is that the LiFePo4 packs are the best if you can afford them. For lithium-ion, the cheapest reliable packs seem to be from Hobby King. Li-ion packs are touchy. At least one person charges theirs outside with a bucket of sand nearby. There are several sources for fire-retardent bags for storing or charging those batteries. There are a few SOTA activators who carry an FT-897 and bigger batteries. wunder K6WRU CM87wj http://observer.wunderwood.org/ On Aug 4, 2014, at 9:01 AM, Jim Brown wrote: > On 8/4/2014 7:54 AM, Bob N3MNT wrote: >> I suggest using two 4S1P LiFePo packs, each being half of the desired >> capacity. > > Thanks -- but this application is to run both the KX3 and KXPA100. > > 73, Jim > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 wunder at wunderwood.org From n3op at hotmail.com Mon Aug 4 12:34:02 2014 From: n3op at hotmail.com (Reggie) Date: Mon, 4 Aug 2014 12:34:02 -0400 Subject: [Elecraft] KPA500 and KAT500 with 2 Transceivers Message-ID: I have the K3 and and Flex 6500, and I would like to hook both transceivers to the KPA500 and the KAT500.

Very low internal resistance and good enough for a few hours of operating at a 100W power level. But the weight is 7 lb. Li-Ion can be two times lighter than LiFePO3. I use 4S1P Li-Ion for KX3. About 2.4 AH and max voltage 16.8V. Weight 6 oz. I use it in two ways: 1. Charge to 16.8V and use with two diodes in series. 2. Charge via one diode in series to 16.2V and attach to KX3 directly. About 15.3V max shown by KX3 as it has another diode internally. The pack has about 0.8V drop at 2.5 A. It is good for a few outings. There are low and high current Li-Ion packs. See http://www.batteryspace.com/4cellspack148v.aspx. I am considering adding 10A Li-Ion to IC7000 for short outings. The battery should weight < 2 Lb.

Are you using the Keying cable from the K3 to KPA500 in addition to the K3 to KPA500 ACC cable? If so, you must either use one or the other OR insert the keying interrupt device. Make sure any external PA keying cable is connected to KEYOUT and not to the PTT jack next to it. Disconnect the mic, key, paddles, PTT in (and KEYOUT) and the ACC cable to see if the K3 powers up in receive. Then start plugging the cables one at a time, checking with each one (start with the ACC cable). When it starts to go into TX, you have found the errant cable - likely a cable configuration problem, but you will then know where to look further. 73, Don W3FPR On 8/3/2014 12:24 PM, mark crossland via Elecraft wrote: > My k3 (427) goes into the transmit state when I connect the cable from the Kpa 500 .

They would each be able to power both the KX-3 and the amplifier, just for about half the time of the single larger battery. So you would have to switch over to the other battery at some point. But using two does offer redundancy in the event of a battery failure. Also, dividing the weight into two chunks may be advantageous for the folks who are humping them up the mountain. 73 Craig AC0DS On 4, Aug2014, at 10:01 AM, Jim Brown wrote: > On 8/4/2014 7:54 AM, Bob N3MNT wrote: >> I suggest using two 4S1P LiFePo packs, each being half of the desired >> capacity. > > Thanks -- but this application is to run both the KX3 and KXPA100. > > 73, Jim > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 craig at powersmith.net > From k2mk at comcast.net Mon Aug 4 14:17:32 2014 From: k2mk at comcast.net (Mike K2MK) Date: Mon, 4 Aug 2014 11:17:32 -0700 (PDT) Subject: [Elecraft] KPA500 and KAT500 with 2 Transceivers In-Reply-To: References: Message-ID: <1407176252753-7591928.post@n2.nabble.com> Hi Reggie, This device could start you off in the right direction.

I'm using a pair of Top Ten Devices RF relay boxes to switch a K3 between a KPA500 and a Ten Tec Titan amp -- one box on the input, a second on the output. For your application, a single box would work.

I did build a 60AH LiFePO4 battery a couple of years ago. If I had to do it all over again, I'd go with two 30 AH batteries. It isn't that the original battery was that heavy (20 pounds), but two 10 pound batteries would be easier to carry than a single 20 pounds. Also it gives you redundancy -- if you kill one battery you have one left. And the cost of replacing it is lower when you do. There is often a price premium for higher capacity cells anyway. 73, Bob, WB4SON From hhoyt at mebtel.net Mon Aug 4 17:04:16 2014 From: hhoyt at mebtel.net (Howard Hoyt) Date: Mon, 04 Aug 2014 17:04:16 -0400 Subject: [Elecraft] JT/heatsinks Message-ID: <53DFF550.2000309@mebtel.net> Hi all, Since the subject of both JT modes and heatsinks cropped up recently in the same Elecraft digest, I will share that my JT customers are very happy with the increased frequency stability after installing the PAE-Kx31 heatsink. Several say they can now use JT65 in contests at 10-12 watts which they could not without the heatsink. This is due to removing most of the heat from the PA FETs to the air instead of letting it soak into the KX3 case. In a KX3 without a heatsink the case becomes much warmer, and this heat conducts and radiates into the xmtr circuitry, which can induce frequency drift. The extended temperature compensation can help reduce the drift as well, and I recommend it with or without a heatsink. It is important to know the KX3 does not need a heatsink to meet all of its stated specs, but decreased frequency drift and increased key-down time at 12 watts is a nice bonus for digital modes. Thanks go to Elecraft for allowing commercial posts on occasion, and where they may be helpful. I will not abuse the privilege!

Everything worked perfectly when I initially set it up. While at the remote QTH, the only change I made was to add the newest firmware to the K3. I have not updated the firmware at the K3 control station, would this cause a problem? I had a person tell me the rig sounds like it has a "defect." Looking at things from the control end, the KAT500 & KPA500 both appear fine, no changes in SWR or power output.

There are many possibilities and we need more details. The new firmware should not necessarily cause a problem, but may if the difference between the two RRC's is significant. There is no reason not to update the control RRC and see if that solves the problem. I also recommend that you repost this on the RemoteRig forum http://www.remoterig.com/forum/index.php if the firmware update does not solve this to receive a response from the developers if needed. 73, Mitch DJ0QN Mitch Wolfson DJ?QN / K7DX Neubiberger Str. 21, 85640 Putzbrunn Skype: mitchwo - Home:+49 89 32152700 - Mobile:+49 172 8374436 Echolink: 3001 - IRLP: 5378 On 05.08.2014 04:22, Jim - KE8G wrote: > Hi All, > I seem to be having a problem with my RemoteRig operation.

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! What is substantially increasing your KX3's operating life worth to you?

To update everyone commenting, I have updated the K3 firmware at the control end, so both are now at the same level. The firmware on the RemoteRig units are identical, no changes had been made there. The coax for the remote station is all new 400Max series fromDXEngineering, which was thoroughly tested when installed two months ago.

The noise is an even static, like background atmospheric noise, about S3 on the s-meter with occasional stronger bursts. This is with no antennas connected to the rig and nothing plugged into the transverter board. Is this a known problem? It would probably not normally be noticed without disconnecting the antennas and waiting for it to occur. It seems to be an electrical contact problem as I can induce it or quiet it by loosening the board's panel screws and pushing on the jacks in one direction or another. I've tried to wipe the contacts by reinserting the board into the socket several times. Same with the TMP cable. But the noise has returned. I'm wondering if the electrical connection between the board's brass standoff bushing and the aluminum chassis is significant... 73, Drew AF2Z From bw_dw at fastmail.fm Tue Aug 5 09:45:33 2014 From: bw_dw at fastmail.fm (dw) Date: Tue, 05 Aug 2014 06:45:33 -0700 Subject: [Elecraft] K3 and hex-beam antenna Message-ID: <1407246333.3733592.149343861.031175A6@webmail.messagingengine.com> I agree totally.

But I know nothing of the details of either, really -- just a satisfied P3 user. I've not yet ordered a PX3 because the KX3 is my portable station and I like to keep it simple. Plus I use the NUE-PSK modem with the KX3 for digital work (instead of a computer).

Last week I went to operate on 6m (which uses the BNC antenna connector) and encountered 99:1 SWR and no detectable RF output. I put the radio on a power meter with 50-ohm load with same results. I set the internal ATU to BYP - still high SWR. So I became suspicious that somehow I disturbed the antenna connection to the ATU during installation of the 2m module that is installed on top of the ATU board. I opened the radio and removed the 2m module and noted the antenna connector was in-place but slightly pulled back from full seating. I reseated it and "carefully" re-installed the 2m module and restored the radio to operation. Testing on 28-MHz I had 8w - great! But 6m showed 1.8:1 and 6w. I retuned the ATU into 50-ohms and recovered 8w on 6m and 1:1. The ATU memory obviously had an old setting left in it. So...when installing the new 2m module in the KX3 that has the ATU board be careful that you do not disturb the ATU antenna connector. --------- A nice plus is testing 2m after this I am able to drive my RFC 2-23 Linear Amp to 30w with 3w. I had replaced the MRF1946 transistor and was concerned that I only had 25w with 4w drive from my HT and only 20w with the KX3. I'm guessing I had a bad coax cable when testing as it works fine now! That is sufficient to drive my RFC 2-317 Linear Amp to almost 150w when I want to operate 2m-SSB. Normally 30w is adequate for 2m FM use. Now the KX3 is in "Full Operating" status monitoring 6m or 2m while my K3 is free to operate other bands from 500-KHz to 1296-MHz. Next test will be trying the KX3 as a mobile radio on VHF! 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From jim at audiosystemsgroup.com Tue Aug 5 13:40:26 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 05 Aug 2014 10:40:26 -0700 Subject: [Elecraft] Maybe a PX3 shipping soon?

When they operate, digital, and while the K3 is in DIGITAL A mode, I see what looks like random white noise across the audio passband of the K3 audio waterfall, (not on the P3 at all), when viewing with any digital program. I have been attempting to characterize this a bit more prior to asking questions so here is what I see: 1. Any strong digital audio signal, causes this issue. 2. Looking at the P3, I see no ill affects. 3. The K3 is feeding my computer's sound card. 4. The same setup only using an Icom 756 PRO III did not do this. 5. I am feeding the sound card from the rear audio jack. 6. I have watched loud signals drift louder, and had the problem start, while I was looking at it. There is an avalanche effect. 7. Turning down the RF gain control, which reduces audio, reduces the issue. Any suggestions to help this go away, or at least behave as the PRO III did?

My KPA500 shows between 12 and 13 dB gain depending on band. 10W in should give you about 180W out, give or take. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org From elecraft at mailman.qth.net Wed Aug 6 13:26:53 2014 From: elecraft at mailman.qth.net (edward kacura via Elecraft) Date: Wed, 6 Aug 2014 10:26:53 -0700 Subject: [Elecraft] K1 Stand Message-ID: <1407346013.79840.YahooMailNeo@web126002.mail.ne1.yahoo.com> Good Morning, Looking for the stand that Elecraft use to sell for the K1.

Do you have the internal frequency counter probe inside your K2? If so, remove it. It should not be plugged in with the KPA100 installed in any case because there is a possibility of spurious responses. I have never heard of it causing a problem on receive, but yours could be the first report. If you do find it is the internal probe causing the problem, let all on the reflector know about it, please. 73, Don W3FPR On 8/6/2014 3:55 AM, paulb wrote: > Hi folks > > K2 here has what appears to be an odd issue with strongs sigs > around 7175Khz > > Tuning approx 5 Khz higher the same signal can be heard several s-points > down. > > Best guess seems to be centred around the 7175 - 7180 range. > > I have a distant memory reading about this many years ago at build, > it's been a while.. > > thanks > > cheers > > Paul b > zl1aly > > > > > -- > View this message in context: http://elecraft.365791.n2.nabble.com/K2-audio-images-strong-signals-40-meters-tp7591965.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 at 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 w3fpr at embarqmail.com > From elecraft at mailman.qth.net Wed Aug 6 16:44:37 2014 From: elecraft at mailman.qth.net (K4KJC via Elecraft) Date: Wed, 6 Aug 2014 16:44:37 -0400 (EDT) Subject: [Elecraft] K2/100 For Sale or Trade Message-ID: <57e53.2e9437b9.4113edb5@aol.com> K2/100 for sale or trade.

Dummy load on Antenna RX 40 meters. Test signals received on 7170 approx 50uVolt, S9 on the K2. Tune to approx 7175 an image is heard. It is not inverted or reversed tune. Leave the K2 on 7170 and tune the test signal to 7184. It can be heard on 7170. Best approx guess is 5 s-points down so probably not a big deal except when the band is quiet and strong signals are nearby. The calibration cable has been removed, Filter setting and mode have no effect. On CW the image signal tunes exactly the same, again about 5 s-points down. Noticed this oddity a while ago when listening to a couple of strong SSB stations during daylight hours at another QTH with low rf background noise. Suspect this has been the same since build several years ago, won't be loosing any sleep over it, more curious if it is something related to vco mixing products somewhere? I have noted the mods on earlier K2 builds, could well be in the same field. thanks for the replies cheers Paul b zl1ajy -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-audio-images-strong-signals-40-meters-tp7591965p7591984.html Sent from the Elecraft mailing list archive at Nabble.com.

I cannot attribute those offsets to anything related to the BFO, but on 40 meters near 7185 kHz, the PLL and VCO frequencies are quite close together, and interaction between the two can cause some "strange happenings". I believe you may be hearing some subset of the effects from the "Weird At One Frequency" problem that was present in earlier K2s. Your K2 has the 'fixes' that usually clear it up included in the above SN 3000 board layout. However, it is not entirely gone in *some* more recent K2s. Don't ask me why, it varies from one K2 to another, I really don't have an answer - it may have to do with construction practices and lead lengths above the RF board, but that is just a guess. As a first pass attack on the problem, use flush cutters and trim everything in the vicinity of U4 so that nothing can act as a short 'antenna'. Look at the leads for RFC15, C91 and C88 which are soldered to the pins of U4 on the bottom of the board. They should be mounted to the pins of U4 with the minimum lead length possible (the lead length on the side away from U4 is not as critical). If you have components (particularly capacitors and resistors and varactors) with significant lead length above the board in the PLL and VCO areas, reduce that lead length to the minimum possible and flush trim the leads below the board. Normal diagonal cutters will not cut sufficiently close to the board - If you do not have them, buy, beg or borrow true Flush Cutters for this task. I can't promise that it will be a total cure, but it may reduce the intensity of the responses. 73, Don W3FPR On 8/6/2014 7:20 PM, paulb wrote: > Hi again folks > > > Update on K2 40 meter audio images around 7175; > > Serial number of build is 6534 with most options installed. > > Dummy load on Antenna RX 40 meters. > > Test signals received on 7170 approx 50uVolt, S9 on the K2. > > Tune to approx 7175 an image is heard.

My RV has a storage locker door 2 feed from the rear ladder and would be an ideal place for the amp/tuner but the interface cable is causing some problems. The manual specifies Cat 6 cables that are STP (shielded); max. 25 feet. My search for a cable locally has failed. Without a trusted source on line I hesitate to pay something in the neighbourhood of $70 cdn for an unknown quality cable. Has anyone tried unshielded cable?; Cat 5E cable?;or whatever!

All of the unshielded CATx cables have very good immunity to external RF and noise if each signaling circuit is carried by one of the twisted pairs. The CATx cable carries RS232, which requires two pairs. The two remaining pairs connect the key line and logic circuit (ACC2). In general, a high quality twisted pair is far more important than a cable shield ff the CATx cable is properly wired (that is, one pair for each signalling circuit). The primary advantage of is higher CAT spec is reduced crosstalk between pairs, which is a big deal for Ethernet, but much less so for applications like this. 73, Jim K9YC From elecraft at ozy.us Fri Aug 8 06:59:45 2014 From: elecraft at ozy.us (Chris Johnson) Date: Fri, 8 Aug 2014 03:59:45 -0700 Subject: [Elecraft] 2M success!

There was only one scary part where you have to slightly bend a toroid on the PA board. I have two KX3's, and will install the second one tomorrow, but so far I am impressed with the accuracy of the unit. My Flex 6700 has the GSPDO and confirms the accuracy. The Elecraft FAQ said accuracy would be within +/- 10hz and it seems to be even better than that. Congrats to Elecraft for making such a feature-rich radio!

A simple TTL circuit over twisted pair will still be quite vulnerable to RFI. Been there done that for many, many, years in datacomm.

I use Fixed-Tune Mode exclusively as it preserves the waterfall. I don't see much use for Tracking Mode as the waterfall constantly gets blurred. The waterfall is very useful for quickly getting to the next workable station in contests. I also use Center a lot since I like to move the DX to the left of the screen (usually) to use more span for the pileup when working DX. I dislike double pumping the FixTrack key since I sometimes don't hit it well enough the second time and it leaves me in the aforementioned Tracking Mode. Yuck. So having "Center" available as F1 TAP would be very useful for both offsetting DX as well as achieving what a FixTrack double TAP does now without the annoying stumble into Tracking Mode. Does anyone use Tracking Mode? And what purpose does Disable Center in Tracking Mode serve? 73 jim ab3cv On Fri, Aug 8, 2014 at 1:48 PM, Mike K2MK wrote: > Hi Jim, > > I don't think any of the buttons that require you to then turn the knob are > directly assignable to an Fn key.

The one who put plates on top of sticks and balanced them by spinning. Every few moments he would start another plate and spin up a few others. It got to where there were so many going at once he could not service the queue and they began to fall. This is about where I am right now :) I need fewer tasks in my inner loop. Propagation has been decent this week. However, I just looked at SpaceWeather and found the SFU has been dropping while the large sunspots are moving over the limb. The sun has been setting earlier so the forty meter net will be getting better. Twenty meters will also improve as the season changes to late summer and early fall. Right now is about the peak of summer in Oregon. Berries and flowers everywhere but everything is drying out quickly with the wind, sun, and warmth. There is a thunderstorm due Monday night which will hopefully be wetter than it is fire inducing.

My Acom 2000A was configured to be the amp The power to the KAT500 was removed and repurposed Appropriate coaxial cables were rerouted to put the 2000A in line (of course) With the help of a good friend it was determined that the issue was that I had removed power from the KAT500 without unplugging the unit from the K3?s ACC jack. When I unplugged that line, the K3 powered up normally. Why does this happen? Is a powered-off KAT500 an invalid state to the K3?

That means that you have some other connection between the computer and the K3 that is causing problems. To completely respond to your situation, we need to know your complete setup between the K3 and the computer as well as what the computer is doing during the process. For instance, what are the settings for PTT -- KEY in the K3? Does the same thing happen when you disconnect the RS-232 cable from the K3? Is Digipan doing something other than just displaying the waterfall? Is the K3 going into transmit? In other words, does the red transmit LED illuminate? Do you have VOX set on for digital modes? I could think that any of the above could be the reason for your stated behavior. What happens if you remove the Line Out cable from the K3 and attempt to set the LINE OUT level? Do you have the computer bonded to the K3 ground with short copper braid? You may have some sort of interaction between the computer and the K3 due to "ground loops". 73, Don W3FPR On 8/10/2014 12:35 PM, Dave Barr wrote: > If I open Digipan while my K3 is on, and then activate "configuration" > on the K3, the config menu selection and change action freeze.

If this happens you will be presented with a totally blank K3 display or hung up K3 and you must turn off the K3's power supply to recover. To avoid this problem you can either switch on the KAT500 before the K3 or switch them both on at the same time, which seems to work too (that's what I do). Here is a procedure to restore the K3 to normal operation: * Disconnect or turn off all power to the K3. * If you have a KPA500, turn it off using the back panel AC power switch. * Turn on the KAT500. * If you have a KPA500, turn it back on also using the back panel AC power switch - you don't need to turn on the front panel power switch. (Some users have reported problems trying to restart their K3 when the KPA500 is off.) * Restore power to the K3. * Turn the K3 power on with the POWER switch. If this procedure doesn't work, try this: * Disconnect or turn off all power to the K3. * Disconnect the K3-KPA Cable from the K3 ACC connector. * Restore power to the K3. * Turn the K3 power on with the POWER switch. If this procedure doesn't work, you may have other problems and it may be time to call Elecraft Customer Service or to try the K3's EE INIT procedure . If the above does work, continue with the following: * Turn the K3 power off with the POWER switch. * Reconnect the K3-KPA Cable to the K3 ACC connector. * Turn on the KAT500. * If you have a KPA500, turn it on also. * Turn the K3 power on with the POWER switch.

The light on the serial-USB converter blinks, and Logger32 shows that the computer and program are trying to speak to the K3, but there is no response.

If you do not do it correctly and in order, things do not come out well. Just more complexities to deal with - by habit: KAT500 on, KPA500 on, then the K3 (which brings up the P3) on. Reverse order when shutting down. I have full battery backup, hence no sudden problems during a power outage.

The specs say the 590's frequency stability is within +- 5ppm, and I've found the higher in frequency I go, the further up I need to tune to zero-beat a station. On 20m, I've found I have to consistently tune up a bit to center. Doing the math, it looks like your KX3 is at least consistently off by 25 or 26 ppm: 133 / 5.0 = 26.6 ppm 190 / 7.335 = 25.9 ppm 250 / 10.0 = 25 ppm 384 / 15.0 = 25.6 ppm 25-26 ppm definitely adds up, and it seems to me the unit is mis-calibrated, but I don't know what the KX3's tolerance for frequency stability is. I'm a new KX3 owner myself so I haven't had enough experience with it to figure out if my unit is off by a small bit or not. Does the behavior change when the unit has been off for a while, vs when it warms up?

I had seen it. Like the other manuals, it says that, "The K3/0-Mini, full-size K3/0 or a standard K3 in ?terminal mode?...," can be used as a client control box. But it still doesn't define or give any detail about this Terminal Mode of the K3. The reason I'm interested is that KG6YPI (and others I presume) has written the RemoteHams client software so that a K3 (and only a K3, K3/0, or KX3 at the moment) can be used as a control head for a RemoteHams connection to a distant server station. This works very well. BUT, when the remote server station is also a K3, the software automatically puts the client (i.e., my) K3 into Terminal Mode. This replaces my client options with those of the server K3. Sometimes (read, often) I do not want those options. I want my own. So, I'm looking for a way to turn the Terminal Mode OFF. Then maybe my client K3 will act just like it does when connected to a server Icom, etc. That is, it will not be as well integrated but it will also not lose its local configuration choices, memories, etc. 73, Oliver W6ODJ On 12 Jan. 2014, at 17:35 PM, Mike Reublin wrote: > Oliver - > > Have you seen this? http://www.elecraft.com/K3-Remote/k3_remote.htm > > 73, Mike NF4L > > On Aug 12, 2014, at 8:26 PM, Oliver Johns wrote: > >> Can someone point me to a writeup of the K3 Terminal Mode?

Therefore, it is really up to an?individual to decide whether he should spend US$90 or a much lower cost to due with the heat issue. It should not?be any rocket science, all you need is a piece of thick metal plate to suck the heat from the PA transistors and with fins to facilitate air circulation. A fully?equipped KX3 costs well over US$1,000, it is a pity that we still have to worry about heat issue under full power digital mode.? Of course, you can also argue that the light duty operators do not have to pay for what they don't need (i.e. heat sinks). 73 Johnny VR2XMC p.s.

I have heard a lot of things about people getting booted for sharing links. Honestly I didn't care. I care more about people having good information about their KX3s. The test showed that the thermal bonding I did was really unnecessary. That took a little of my time and like thermal paste always does, caused a mess.

I didn't think that was even possible. I understand that your KX3 may not display the correct frequency when tuned in correctly to an ssb signal, but that's just a matter of running the frequency calibration on the KX3. As for crawling up and down the band as a result, if you tune in the SSB signal so that it sounds proper, the other station should be receiving you at the proper 'pitch' as well. No need for anybody to change the VFO dial if you're tuned in. Yes, your frequency display may not agree with the other stations frequency display, but tuned-in is tuned-in (unless the KX3 TX and RX can truly be on different frequencies). Hope I didn't muddy the waters any further with this; just trying to understand what's happening. 73, Dale WA8SRA > I am guessing I have mis-set some menu-settable parameter and I am looking > for advice as to which one I might have mis-set so I can solve the > following > problem: > > I am finding that I must set my KX3 receive a few hundred hertz higher > than > the actual frequency on which a station says he is transmitting so that I > achieve natural sounding voice on receive.

The amp has a keying input, when it goes to ground it keys the amp. I have the ACC2 module/cable plugged into the ACC2 connector of the KX3. The KX3 keys the amp to xmit but it does it on all bands, not just 2 meters. The XV2 ADR write up in manual says to set it to TRN CTRL but that option does not come up in my menu? I am using the RCA connector on the ACC2 cable and not sure what the 1/8 female stereo connector is used for? The menu for ACC2 IO is now set to LO-PTT. I have spent quite a bit of time with this but not sure what to do next?

It is not a per band setting. If it is set to LO-PTT, it will be active anytime the KX3 is keyed. There is no way I know of to restrict this output setting to any particular band, so you will have to come up with an alternate method of keying the external amplifier if keying it when not in use is going to be a problem. If your 222 MHz transverter is an Elecraft XV222, you probably want to set the ACC2 menu to TRN CTRL so the XV222 will be sent the band data from the ACC2 and be selected when you set the KX3 to the 222 MHz band. Note, you cannot use the ACC2 to send band data to the XV222 and also send PTT to the external amplifier. 73, Don W3FPR On 8/13/2014 12:12 PM, ejkkjh at gmail.com wrote: > I am using my KX3 2 meter module with a small amp.

I bought a heatsink from KB8UHN (see his QRZ page) . This heatsink is smaller, both in thickness and fin size. I was happy running winmor/RMS with the stock KX3 from home running 3 watts but I thought a bit bigger heatsink would allow me some higher power and with the diminutive size of John's heatsink I would not be snagging all sorts of items on the picnic table while portable. Once I installed it I did some totally unscientific testing with the following results: Test 1: start temperature of PA: 32 after 5 minutes: 56 Test 2: start temperature of PA 30 after 5 minutes 54 Test 3: start temperature of PA: 28 after 5minutes 53 These results are summarized and I will happily sent you the total Xcel spreadsheet. The above data was taken at 10 watts into a dummy load with the key locked down (on 20 meters) and are expressed in degrees Celsius. Room temperature was about 25 degrees C, no breeze or air movement. These temperatures compare very favorably with any other data that I have seen posted for the much more expensive KX3 Heatsinks. The heatsink also allows you to use the Sidekx handles and cover. I can't think of any mode that I would use my KX3 on which would require a larger heatsink but your operating habit may dictate otherwise.

There are many nuances... conduction, radiation, and convection. Often optimizing for one may diminish another characteristics. There are many trade-offs. Copper is a better conductor of heat flux than aluminum but it adds more weight. Black bodies radiate heat faster than than bare metal but they also absorb heat from sunlight faster so do you optimize for dark or sunlight? I think the good news take away is this an easy area to do your own experiments and homebrew. You don't even need a thermometer. It's already there.

What it tells me is the thermal mass of the heat sink is more significant than the interface between radio and heat sink. Both are aluminum, I assume, so thermal conductivity is probably the same. I would have expected a uncoated smooth surface interface would work better, but in this example apparently no difference is detectable. I have one of the "Coo!er KX" heat sinks installed on my KX3. http://www.ve7fmn.ca/ I was an early buyer so Fred has done quite a bit of development since I bought mine. I opted for the unpainted bare aluminum, thinking it might conduct a bit better. The you-tube demo would suggest it may not have any significant difference from the powder-coated heat sink which looks nicer. I performed the Elecraft Thermal Compensation Procedure on my KX3 and then ran some heat vs frequency tests using 5w RF output on 6m: http://www.kl7uw.com/KX3.htm http://www.kl7uw.com/KX3_FREQ_DRIFT_TABLE.pdf Note the first ten curves were done before performing Temp Compensation. Frequency drift is up to 30-Hz in one minute key-down. After the Compensation drift is most noticeable in the first couple minutes and tames to 5-Hz after 15-minutes running. The frequency "bump" at 20-seconds running is probably due to a bad data point in the Temp. Comp. curve so I plan to repeat the Temp. Comp. Procedure. I do not have curves published after installing the heat sink but drift drops to about 2-Hz, after the first three sequences from a cold-start. I will repeat these tests for the 2M module. Regarding drift at HF I would expect it to be proportionately less as Frequency is lower. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From vr2xmc at yahoo.com.hk Wed Aug 13 20:53:41 2014 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Thu, 14 Aug 2014 08:53:41 +0800 Subject: [Elecraft] Some "Cool" heat sink info.

Clearly, the result was not that successful and I eventually settled down on a heat sink available from the commercial market. I have been adopting that kind of 'experimenting' attitude for ham radio for years,? Sometimes, I succeed but there?were many times when I completely failed.

Generally I used my tube amp but I wanted to see how the KPA500 would perform. Normally I run 600 watts out of the KPA500 but for this operation I cranked it down to 500 watts. We're talking continuous CQs and contacts over 2 hours of straight through operation. The KPA500 worked flawlessly. Having said that it is important to mention something about temperature and fan speed. It didn't take long for the temperature to get up to 65C. I eventually set the idle fan speed at speed 4 which tended to keep it at 65C or below. For me, speed 4 sounds about the same as the fan on my legal limit amp. The surprise occurs when the temperature creeps up to 70C. The fan jumps to speed 5 (or maybe 6) and it is loud. Luckily it only takes 5 to 10 seconds to bring it down from 70C to 65C. It looks like Elecraft did a fine job controlling temperature for heavy RTTY operation. I would not hesitate to recommend the KPA500 for RTTY contesting but I would certainly want to mention that the occassional higher fan speeds might annoy some operators. 73, Mike K2MK -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-heavy-RTTY-observation-tp7592076.html Sent from the Elecraft mailing list archive at Nabble.com.

I can customize them for other bugs such as the Japanese Hi Mound ("Coffin") bug, European made (metric sizes) bugs, etc. as long as you can supply me with the diameter (round) or thickness (flat) of the pendulum and a sharply focused digital photo of the actual bug you want it for. There is no extra charge for this customization as it stands right now. They can be made out of either aluminum or brass. They mount to the arm with a socket head set screw and the proper Allen wrench is included along with a printed set of instructions explaining installation and proper adjustment. Also, they are made entirely by hand so there may be slight differences between each one (won't affect the operation at all). I recommend the aluminum ones as they are lighter and don't affect the top speed of the bug as much as the brass ones do. The prices are $20 post paid for the aluminum and $25 for the brass ones to U.S. customers. I was charging $20 for either aluminum or brass, but I've run out of surplus brass and had to buy some at current new brass prices which are considerably higher than what I had to pay for the surplus stock. Internationally, they are $35 for Aluminum and $40 (U.S. Funds) for the brass ones. They will be sent "International First Class" mail. If you decide to order one or more, I will need the make/model of the bug(s) you want stabilizers for, whether they are "left" or "right" handed (the bug, not you) and be sure to include your mailing address as well.

I am about to install a new dipole that will pass within ten feet of one of the interior units (that would be measured through the wall). I already know that the system has produced no interference to any reception - however, I am concerned about how being close to a transmitting antenna will effect or not effect the unit/system. The antenna's location will meet safe human exposure limits for the bands/power used - 160/75/40. I am assured by the installer that RF is not a problem and not to be concerned - of course that is not in writing. Attempts to email and call Mitsubishi have not been informative. Hence my question: Has anyone had difficulties with the control systems of their HVAC systems caused by RF from a nearby transmitting antenna? I run the KPA500 all the time - so consider this a 600 Watt station.

If you look at the block diagram on the Microham web site, the CAT interface comes from the internal CPU in the Microkeyer. Assuming my memory is at least partially still intact, I believe that was the problem, the firmware in the Microkeyer interferes with the K3 handshaking with the K3 Utility during FW loads. What are your connectors? The K3 is a 2 row female DB9 if I remember right [it's buried back in the non-wireless part of my station and its very dark back there] You can probably get a USB-RS232 adapter locally cheaper than paying shipping costs. The Elecraft adapter I have uses the Prolific chip set and runs fine. Some say the FTDI chip set is more reliable. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 8/14/2014 4:02 PM, Kurt Wiksten wrote: > Thanks to everybody for your advice. > But my problem still not solved, because I am communicating with the K3 > via my Microkeyer2.

Other K3Utility functions work fine through the Microham device. If you have a real serial port on the computer, that is the preferred connection, otherwise a good USB to serial adapter is the best answer. The preferred adapter is one using an FTDI chip. Others may work (and I can also recommend EdgePort). BTW - there are counterfeit FTDI and Prolific USB to serial adapters on the market. Both Prolific and FTDI have created new drivers for Windows 7 and above that detect those counterfeits and render them unusable - so steer clear of bargain priced adapters whose instructions tell you to turn off Windows updates and run their 'special' drivers. The Elecraft KUSB cable uses an authentic FTDI chip. I have also had success with a Keyspan adapter that was supplied for testing by a customer. 73, Don W3FPR On 8/14/2014 7:02 PM, Kurt Wiksten wrote: > Thanks to everybody for your advice. > But my problem still not solved, because I am communicating with the > K3 via my Microkeyer2. > Reading the K3 Utility Helpfiles shows that it might be a problem that > my USB to serial connection is > via my Microkeyer2 and the recommendation is to change the cabling so > that the PC is > connected directly to the K3 and that cable does not fit the K3 RS232 > port. > I suppose I will have to order the KUSB-cable from Elecraft.

So if you encounter "strange happenings" with your HVAC system due to RF, the supplier is bound to take corrective action. Some may not understand, and some may not even know of the requirements, so at worst case, you may have to get the FCC involved for resolution. The most published FCC class B information regards radiation from the device(s), but there is also regulations regarding susceptibility from radiation from licensed services. The fact that you addressed the RF interference situation with the installer should go a long way (document that conversation for yourself with dates and names), and for a reputable company should be as good as a written statement (I am no lawyer, but it makes sense to me). 73, Don W3FPR On 8/14/2014 4:20 PM, W2BLC wrote: > I recently installed a Mitsubishi mini-split system and now have an > antenna concern.

Determination of Priority is democratic to some degree (Squeaky Wheel and other industry standard methodologies). But in practice it involves crystal-ball-gazing, head-counting, arm-wrestling-over-a-beer, and a healthy dose of what-we-have-time-for. It is not practical for us to publish the lists. They change daily and contain a lot of firmware-speak. We'd rather spend time actually making changes than on sanitizing lists for public consumption. This is also the reason that we can't make announcements of the form "We will not ever get to feature X." (Imagine trying to do that with your personal Home Repair task list. Would your spouse let you unilaterally decide to remove some of them?) We'd rather be optimistic about it, since you never know when one of our overworked engineers is going to get some unexpected free time. The most useful guidance I can give you is this. If only one or two users are affected by a particular change, it is less likely to be implemented in the near future. If nearly all users are affected, it darn well better be fixed instantly. Everything else is in a sort of gray zone (see "Determination of Priority," above). I take responsibility for any muttered oaths against Elecraft pertaining to implementation delays. If it's any comfort: I read all the mail and lose sleep over things we can't get to. All I can say is that we try to make the best decisions we can, given engineering time available. 73, Wayne N6KR On 8/14/2014 4:55 PM, Sam Morgan wrote: > I doesn't have anything to do with one of their new products, so there > is no reason to waste electrons asking or commenting. > > They will get around to it when and if they ever decide to, or are > allowed to, work on something P3 or K3 related, and no amount of asking > will change that. > > Sam > > On 8/14/2014 4:35 PM, XE3/K5ENS via Elecraft wrote: >> I must be the only one that has bought a P3 with the SVGA board.

Fortunately the electronics in your HVAC system is fairly simply and easily shielded. However when susceptibly problems occur with Japanese designs it can be very difficult to get them to respond. Let's hope you don't have to go there. What concerns me more is the noise/interference generated by some high SEER HVAC systems. These systems achieve variable speed by using variable frequency inverter driven motors. These can be a pain in two ways. First they radiate noise that can extend well above 160M. Second, they can induce harmonics on the powerlines. Line filters similar that what your kilowatt amps use are needed between the HVAC system and the 240vac power lines. Some of the HVAC systems have the filters built in and others don't. Let's hope they have done their homework and cleaned up their systems. With your system operating in the AC mode you will want to scan 160M for noise or hash. You may want to check 80M too if 160M is dirty. Don't take acceptance of the system until it is proven clean. 73, Fred, AE6QL -----Original Message----- >From: Don Wilhelm >Sent: Aug 14, 2014 4:54 PM, >To: W2BLC , elecraft at mailman.qth.net >Subject: Re: [Elecraft] OT Antenna location concern > >Bill, > >All products are required to withstand RF susceptibility levels.

So far I have been on both FO29 and AO7. FO29 is fairly easy bird to get through, AO7 can be difficult. I have not tried SO50 yet. I use the compute to control the az / el rotors but not the doppler shift. I adjust for doppler manually, using the tried and true rule of only adjusting the higher of the uplink / downlink frequencies. This works well enough for the past 30 years of satellite operation, as the QSOs are short and the satellites are (unfortunately) largely empty. On FO29, if the pass is very high elevation, say above 60degrees, I can get into it barefoot with the 3 watts from the KX3, but don't expect to do that near the horizon. Generally speaking I use 10 watts or less for most of the pass. On AO7, an external preamp is needed, especially with the only 3 elements yagi. Again, on a high elevation I can hear fine without an external preamp, but it is definitely helpful. AO-7 Downlink (145.950 MHz) - Elecraft KX3 with 2 meter module 3 element yagi Mirage B-34G amp (includes Gaasfet preamp) Uplink (432.150 MHz) - Yaesu FT-857 11 element yagi FO-29 Downlink (435.850 MHz) - Yaesu FT-857 11 element yagi Uplink (145.950 MHz) - Elecraft KX3 with 2 meter module 3 element yagi Mirage B-34G amp OBTW - Starting a road trip in a week, taking the KX3 along for both SOTA and satellite field operations. -- Mike Herr WA6ARA DM-15dp Home of The QRP Ranch No trees were killed in the sending of this message, however, a large number of electrons were terribly inconvenienced.

I am the author of Win4K3Suite. With a customer base of a few hundred users (not one or two users) I have numerous times reported bugs and deficiencies in the Elecraft API through the elecraft support channels as well as directly to Wayne and have never had the decency of getting a reply. Support replies and tells me ?It was forwarded to Wayne" Not even ?we are aware and this is in a future release?. This has been very frustrating and my response to my customers has been ?I told them about it and haven?t heard anything?. For a company that provides such a comprehensive API and support, to totally ignore comments from people who use their API as extensively as I do, is very unprofessional and very frustrating. The only time, I have had a resolution to an issue is when a well know person from Microham, reported the issue in a much more, how can I say, forward way that I do, and it was resolved within a month. The fact is that Elecraft has an API and encourages developers to develop products. But somehow, it seems to me if the products do not match their ?vision? on what the radio should be they are ignored. That has been the case for me. Here is something important: I have about 20 users that bought the radio because of my software. It hides the complexities and makes it very easy to use. Is this against the Elecraft wishes for their radio? I have to think so since I have 4 times requested to have my software listed on the Elecraft Website, under third party software and even Eric asked me to send a blurb but I never got a response at all. 4 times over 1 and 1/2 years. So, unless many users ask for something on the forum, the priority is low. If a developer who has a few hundred users asks for something in a nice way, several times, it?s ignored. So is this the future of Elecrafts third party support? Does my name have to be J** to get something done? This is extremely frustrating, and I have a couple of hundred people that want a few things to be done but all I can tell them ?I asked but never heard ANYTHING?. So, maybe it?s time to be a ?squeaky wheel? like now. Tom Blahovici VA2FSQ Win4K3Suite.

Even a low speed (audiably quiet) fan will have a marked effect for the better, for minimal extra 12V current load.

Elecraft is quite responsive (issues a fix) if an issue is serious. However, I have always received an acknowledgement of requests for feature/API change when submitted through the developer channels. That answer has not always been what I wanted to hear and I have a long list of requests that have either been rejected or are on the low priority list (in other words, not likely in my lifetime). Others are correct, the Elecraft development staff is small. That means, of necessity, a large percentage of their time must be devoted to work on new products with the majority of support for existing products reserved for issues that cause equipment failure (e.g., the input queue overflow). On the other hand, when it comes to issues that cause improper operation, Elecraft is orders of magnitude more responsive than some logging software developers who do things that cause crashes (like fast polling during transmit). 73, ...

Historically, proprietary platforms have been eliminated or converted to either completely Open Source or partially, similar to what Apple did: the platform is semi-open in the sense that nothing goes to Production without their validation and approval. I believe this model could work very nicely for Elecraft. Publish the bare-bones design and have the community take a stab at it. You could still maintain the basic approach and have some immutable things in there, that we can't change. But majority of these requests are outside of the basic design. Such model allows a company to maintain a relatively small support staff but still be "out there" as far as usability and community support.

Wine is the Windows emulator for Linux and like all emulators (mostly) it has issues with hardware. Because its an abstraction layer between the OS and the target device. Why don't you just use Linux natively? There are programs that run on Linux, although not as many as there are for windows. After much trouble and frustration i decided to just run Windows 7 in Parallels on my MacBook Pro. I use HRD and a few other things and i have to run Windows, but i refuse to have an actual PC at home. Been a mac user for a decade. If you must have Linux for some reason you're much better off running Windows inside of it (VMWare or VirtualBox). Wine is a fairly poor performer for hardware-based stuff. It works ok for MS Office and such but not for this. __________________ Slava (Sal) B, W2RMS W2RMS at arrl.net On Aug 13, 2014, at 5:50 AM, Joel Black wrote: > Bill, > > Look up creating "sym links" for Linux.

Historically, proprietary platforms have been eliminated or converted to either completely Open Source or partially, similar to what Apple did: the platform is semi-open in the sense that nothing goes to Production without their validation and approval. I believe this model could work very nicely for Elecraft. Publish the bare-bones design and have the community take a stab at it. You could still maintain the basic approach and have some immutable things in there, that we can't change. But majority of these requests are outside of the basic design. Such model allows a company to maintain a relatively small support staff but still be "out there" as far as usability and community support.

We sell hardware (Ethernet controllers) and the driver I support is open sourced Linux and FreeBSD. There are also closed-source versions but I only do backup-support on those. Yes, it would require more support on Elecraft's end but it wouldn't be impossible to manage, just hard. There's a lot of repeating, "If you can't reproduce it on the official X version driver, then you're on your own." But then again there are a lot of bug fixes that other people can do for you. I don't blame them for not doing it, but I'm still on the "It would be nice" side of this.

It isn't clear whether you mean that the P3SVGA doesn't work well displaying weak signals, or that the decoding doesn't work well. First, the decoding is done by the K3, and the P3SVGA simply displays it in a more user-friendly form. Second, the SVGA displays a completely different FFT with more bins (better resolution), with the same frequency and amplitude settings of the P3. The P3SVGA can be set for a very long waterfall time, which is quite useful finding holes in contests and DX pileups. And both the P3 and P3SVGA are VERY good at finding weak signals if set for maximum averaging and fixed tune mode. I regularly use a P3 to find action on VHF, and I've got an LOTW QSL from Iraq because the P3 found him somewhere different from where he was spotted. I work CW, SSB, JT65, FSK441, and ISCAT-B on 6M, so I set the P3 to monitor from 50.080 to 50.280. This lets me see action on CW and SSB when I'm in RX mode of one of the WSJT modes. I've picked up at least a dozen grids this season because I saw them on the P3. 73, Jim K9YC From arlenfletcher at mac.com Fri Aug 15 12:34:10 2014 From: arlenfletcher at mac.com (Arlen Fletcher) Date: Fri, 15 Aug 2014 09:34:10 -0700 Subject: [Elecraft] [KX3] KX3 Supply Voltage reading low In-Reply-To: <07BA8B5D-EE2A-4D13-8A08-BE3EBF439CDC@cox.net> References: <53ECF52D.8060301@gmail.com> <53ED46B2.1040606@embarqmail.com> <53ED52A8.5020709@subich.com> <027001cfb824$451214a0$cf363de0$@net> <07BA8B5D-EE2A-4D13-8A08-BE3EBF439CDC@cox.net> Message-ID: Greetings all!

When I power the KX3 from an external 12V SLA battery - which reads 12.2V on my Fluke DMM - the KX3 reports 10.2V while idling. I might expect the KX3 to report slightly less than 12.2V if there is a diode on the supply input (I haven?t checked the schematics), but 2V seems like a significant difference.

The decoding of the digital signals I could care less how that works. I don't use that function. I am saying that on the P3 screen with the NB on I can see weaker signals than I can see on the P3SVGA screen. The noise blanker does not work on the P3SVGA board. I would like to see the NB function with the P3SVGA screen. I also stated that to read the ad for the P3 it reads that I should expect to see the same screen on the P3SVGA as I see on the P3. Only with higher resolution. But that's not true. Since the NB only works on the P3 the screens are different.

Repeating my advice -- to see very weak signals, we need to do a lot of averaging to get rid of the noise. This is not a "blanking" function, but rather how averaging a spectral display causes random noise to cancel itself out, while discrete signals do not. There are separate display settings for the SVGA and for the P3. The SVGA settings are accessed via the SVGA selection on the Menu. Also -- the K3 NB is really two NBs, and the one that looks at broadband noise DOES work in both the P3 and P3SVGA. 73, Jim K9YC From lisa at elecraft.com Fri Aug 15 13:14:13 2014 From: lisa at elecraft.com (Lisa Jones) Date: Fri, 15 Aug 2014 10:14:13 -0700 Subject: [Elecraft] Huntsville Hamfest this weekend.

It is more of a visual aid and does not need to worry about the audio. My understanding of this NB is that if used on the audio all you would hear is sounds like a typewriter. The NB in the P3 does an excellent job on the type of noise it is designed to be applied. Before you continue I would suggest you try the NB for the P3. It is wonderful here at my location. All I asked was if there was any news about implementing this NB for the P3SVGA add-on. Since I have the P3SVGA board and a nice display I'd like to see the display without all the extra noise. I hate how every time someone makes a comment that they think is negative to Elecraft the person making the comment is flamed. Most of the flamers have little idea what's happening and I wish they'd keep their mouths shut.

I intend to use my KX3-2M and K3 + 432 transverter* for crossband duplex satellite operation. Typically current satellites uplink on 2m and downlink on 435, so I have added a RFC 2-23 linear amp which can provide output up to 30w on 2m to a 7-element yagi which is way more than required for satellite operation. A low-noise preamp is used on 435-MHz with a CP x-yagi. MY az-el satellite rotator requires repair of the control box so not QRV for the satellites at present. The KX3-2M appears to work well on area repeaters and good on a short SSB test. *L432-28 transverter with synthesized PLL by DEMI; has two frequency ranges: 432-434/435-437 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From cak at dimebank.com Fri Aug 15 12:51:58 2014 From: cak at dimebank.com (Chris Kantarjiev) Date: Fri, 15 Aug 2014 09:51:58 -0700 Subject: [Elecraft] FS: KPA100/KAT100 in EC2 In-Reply-To: References: Message-ID: <53EE3AAE.60008@dimebank.com> Hi all ... it's been a few years since I've made any noise here (and a little while since I've been on the air).

In this mode, PTT wouldn?t key the radio, it would simply activate VOX. If PTT was not keyed, the radio would not respond to audio and key the transmitter, even with VOX turned on. Another way to do this of course, would be a switch in the audio path of the mic (the reverse of a broadcaster?s ?cough? switch). Interestingly (to some perhaps), my CE-100V works this way with its D-104. With PTT not pressed, no DC is applied to the FET preamp in the mic. So I leave the radio in VOX mode, but still have to invoke PTT on the mic for the VOX to actually work. It is actually quite handy ? when you?re not going to talk for a bit, you can cough, sneeze, yell at the dog, whatever, and the radio won?t respond.

Put a relay in series with the resistor and operate that relay from the foot switch. The microphone will not respond until the relay closes. The footswitch would *not* connect to the K3 PTT IN. This is not normal operation, and the original poster is asking for a new function from Elecraft. I don't think many hams would take advantage of a function like that (at least I would not), so the most expedient way to implement it is by use of some external device (you can have the function now rather than waiting for Elecraft to develop it). Some microphones already have a section of the internal PTT switch wired in series with the mic element, and those could be easily modified by disconnecting the PTT function connection to mic plug pin 2 and running the K3 in VOX. In other words, the mic PTT switch closes the AF line between the mic element and the plug, so VOX will only work when the PTT switch is closed. 73, Don W3FPR On 8/15/2014 1:33 PM, iain macdonnell - N6ML wrote: > I think it's an interesting idea.

Jim, that information is incorrect. The K3 NB can not possibly have any impact on the P3 or P3SVGA as the IF pick-off is at the output of the first mixer - *before* any noise blanker gate. To confirm this, examine "K3 RF Board 4 of 4" from the June 2010 K3 Schematics package (on-line) and you will find the IF tap from which the P3 is fed is connected to pin 1 - the input - of J77 the NB connector which is *before* any NB action. In order for the hardware IF to be reflected in the P3 the P3 would need to be fed from pin 7 of J77 (NB output). 73, ...

Perhaps you can share your findings of the short fall. I may be in error, but I believe the P3SVGA is operating on the data from the P3 FFT. I expect a panadapter to display what is impinging my antenna, not the result of processing later down the line. I can see signals in respect to noise, and that is what I would want, not signals in spite of noise. But then again, I am old school.

Arlen, My first thoughts are that you need to fully charge the battery. I don?t have a lot of experience with lead acid batteries, though. The input diode (CMS04 if my memory is correct) should only account for about 0.2v at KX3 receive current levels. I haven't looked at the schematic for a long time, so I can?t remember what else is in the path from the connector to where the internal voltage reading is measured, but I seem to recall at least one FET (on/off switch) and a current sensor. The 12.2v is getting pretty close to the no-load fully discharged 1.95v per cell, and the 10.2v is pretty close to the 1.75v per cell of a fully discharged SLA battery. At these voltages, the discharge curves are getting pretty steep, so the addition of the KX3 receive current could cause the extra drop you are seeing. Of course the problem could also lie in the power cable, connectors, or even inside the SLA battery itself. A check with a fresh, fully charged SLA battery will help isolate the problem. You will see voltage drop along the cable, even with a freshly charged battery, but 2 volts total sounds a bit high. I just pulled out an SLA that I haven?t used for a while, but it has been charged recently, and the voltage difference between the battery voltage (no load read by a cheap DMM) and the KX3 display (while in receive) was less than 1 volt. Hope this helps.

When I power the KX3 from an external 12V SLA battery - which reads 12.2V on my Fluke DMM - the KX3 reports 10.2V while idling. I might expect the KX3 to report slightly less than 12.2V if there is a diode on the supply input (I haven?t checked the schematics), but 2V seems like a significant difference.

The decoding of the digital signals I could care less how that works. I don't use that function. I am saying that on the P3 screen with the NB on I can see weaker signals than I can see on the P3SVGA screen. The noise blanker does not work on the P3SVGA board. I would like to see the NB function with the P3SVGA screen. I also stated that to read the ad for the P3 it reads that I should expect to see the same screen on the P3SVGA as I see on the P3. Only with higher resolution. But that's not true. Since the NB only works on the P3 the screens are different.

Those tools include noise blanking, noise reduction, agc, selectable filtering, a panadapter, etc. Each tool applied as appropriate to the conditions. 2) The panadapter is simply one of those tools to show me the activity over a band of frequencies, whatever that activity might be.

Joe, I've never studied the schematic or signal flow in the regard, but I often study the screen of my P3, which DOES show reduction of noise when the wider NB is active. 2-4 dB is typical for the types of noise for which it is effective. I appreciate the alert to the existence of the P3 NB. I last updated firmware about six months ago, and it was not in that version.

I?m guessing that perhaps you?re considering that the voltage of the SLA is sagging when it?s running the KX3. I wondered that too - so I measured across the terminals of the SLA while it was powering the KX3. It still measured 12.2V, so it wasn?t sagging. The battery (and it?s little charger) report it as being fully charged - though I?m dubious about the accuracy of the little wall-wart charger. :-) Arlen AA7F On Aug 15, 2014, at 11:42 AM, rv6amark at yahoo.com wrote: > Re: ?reads 12.2V on my Fluke DMM - the KX3 reports 10.2V while idling. > > Arlen, > > My first thoughts are that you need to fully charge the battery.

A check with a fresh, fully charged SLA battery will help isolate the problem. You will see voltage drop along the cable, even with a freshly charged battery, but 2 volts total sounds a bit high. I just pulled out an SLA that I haven?t used for a while, but it has been charged recently, and the voltage difference between the battery voltage (no load read by a cheap DMM) and the KX3 display (while in receive) was less than 1 volt. > > Hope this helps. > > Mark > KE6BB From wes at triconet.org Fri Aug 15 18:11:25 2014 From: wes at triconet.org (Wes (N7WS)) Date: Fri, 15 Aug 2014 15:11:25 -0700 Subject: [Elecraft] Slow-scan TV (SSTV) display on the P3 and PX3?

VOX terrifies me, it can really mess up a net if left on accidently and the phone rings, we had to move the whole net once when someone's "mom" called. I believe a software fix would make this for reaily available, and VOX a safer feature. I have been working on this for a year, I already have all kinds of "gizmos" connected to the K3. With the help of Elecraft support (Keith) and other suggestions also. The Plan is: Jumper ACC Pin 7 TX INH through a SPDT switch to Pin 4 PTT IN (common with RCA PTT IN) already connected to Pedal. Switching ACC Pin 7 to Ground will "undo" the TX INH.

I don't want VOX on all the time to key the transmitter when I sneeze, someone talks to me, I murmur, phone rings, wife pours hot soup in my lap, etc. WHY? 1>To avoid accidentally transmitting while listening; I want to control transmit (VOX) by pushing my foot pedal turn VOX on. A net control/relay has to do 2+ things already, read the list, flip pages, mark response, record traffic by destination and call sign, etc. Or to type on a keyboard (I'm a 2 handed typist). Pushing the VOX button on/off each time with my little toe is very awkward. 2>While transmitting (as net control) I wish the VOX to be active so that I can take advantage of VOX {to listen between words}. VOX when talking switches to listen during the brief pause between words, and as you breath the amp switches in milliseconds.

The decode on the K3 front panel is cool for computer-less work, but as soon as you have a computer it becomes less useful. This is from a serious contesting perspective. When I'm running I'm using several screens to pull out marginal signals. Those screens buffer the decoded text long enough for me to look at all of them and make a decision about what is correct. By this time the small display on the K3 has scrolled away. If on the other hand you had an overlay of text** on the P3 display I now have it buffered long enough to add it to my decision path as another set of data from a decoder that has different characteristics than my other decoders (MMTTY, 2Tone, hardware modems, etc.) A feature like this would seem to have a broader audience than for SSTV, but perhaps I'm partial...;) ** I would overlay the display with white text over the color waterfall so that I can still see waterfall history behind the text.

I let MixW run on 14230 all one weekend and then went back and looked at some of the images [MixW saves all received images]. A surprising number [like half] were unanswered CQ's with pictures of scantily clad women. I haven't checked it in a number of years. There are some digital SSTV signals starting around 14233 or so ... I don't know anything about them. > > If we did consider adding SSTV, we'd need to decide which SSTV > format(s) to support.

There's a half dozen or more analog modes, most of what I decoded was one of the Scottie's [there are several]. I suspect that, to be attractive, your software would need to decode the digital burst at the beginning and auto-select the mode like MixW does. We all get to use whatever modes we want ... personally, I was bored by SSTV and haven't looked at it in years.

The displayed voltage should be the higher of the internal batteries or the external batteries. There is a diode drop, so expect a reduction of 0.3 volts from the measurement at the battery. I suspect that the battery charger is dragging down the voltage from your SLA battery (inside the KX3). As another guess, the cable from the battery to the KX3 may be suffering from poor connections that are causing a significant voltage drop by the time the voltage reaches the KX3. It would be nice (and informative) to measure the voltage at the K3 end of the power cable with your DMM (with the KX3 turned on). Is this an older KX3 or a relatively new one? The reason I ask is because the early KX3s did not glue the power connector to the PC board and could cause a separation of the connector voltage to the KX3 board. That can also result in a high resistance where the connector is soldered to the board (and produce a significant voltage drop. I would suggest that you remove one or more of the batteries and see what the voltage reading from the external battery may be. That will eliminate any concern that the voltage of the internal batteries is 'dragging down' the voltage from the external supply. I would also recommend that you use an external 13.8 volt supply rated at 5 or 6 amps if you can to see what the voltage reading results might be. A fully charged SLA battery showing 12.2 volts open circuit is not fully charged, and the internal resistance of the partially discharged battery may be giving you confusing measurements. 73, Don W3FPR On 8/15/2014 6:12 PM, Arlen Fletcher wrote: > David, > > I wasn?t aware of the ability to choose which supply (internal Vs. external) was being reported!

After not being charged for over a week, they all measured in excess of 13 volts. So my conclusion is that your wall-wart charger is not fully charging your battery. A normal float charge for an SLA battery should be at 13.8 volts - and even that is not perfect because the best charging voltage varies with temperature. A good 3 stage charger designed for charging SLA batteries is the best to use, and those are a bit more expensive than the "wall-wart" chargers, but worthwhile if you consider the life of your SLA batteries important. 73, Don W3FPR On 8/15/2014 6:03 PM, Arlen Fletcher wrote: > Hi Mark, > > Thanks for the response! > > I?m guessing that perhaps you?re considering that the voltage of the SLA is sagging when it?s running the KX3.

It includes the following changes: * CW-IN-SSB-MODE IMPROVEMENT: The operator?s specified CW QSK delay is now used during CW-in-SSB-mode, even with *external* CW keying. (This was already working with the internal keyer.) * 2-M DIRECT FREQUENCY ENTRY FROM OTHER BANDS: Range is 120-168 MHz. Note: Sensitivity falls off as you move out of the 144-148 MHz range. * INCREASE IN ALLOWED TX CURRENT: Allows full-power output on some bands where previously a drop to 5 watts had been observed (with an external 12-14 V supply). This corrects a problem observed by a customer using rev. 2.12 on 12 meters. We had in fact set the TX current limit too low. If you're interested in giving this release a try, please email me directly. I'll take the first 20 or so, depending on when I get the dinner call.

If you've never tried this feature, now would be an excellent time. Signals are coming in from all over the world, from about 14.080 MHz up. You'll need to go into DATA mode, select FSK-D sub-mode, and turn on text decode. You can use the CWT meter function to help tune in signals. Refer to the owner manuals for details. Of course you can also send RTTY with the K3 or KX3, too -- with the keyer paddle. Once you're in FSK-D mode, just set your code speed and start sending. To truncate the 4-second idle time, send "..--" (the Elecraft "IM" prosign, which means "IMmediately terminate the transmission"). This, too, is further described in the manual. 73, Wayne N6KR From k1nd at comcast.net Fri Aug 15 22:21:57 2014 From: k1nd at comcast.net (Jan) Date: Fri, 15 Aug 2014 22:21:57 -0400 Subject: [Elecraft] RE; Slide Rules Message-ID: <53EEC045.5000203@comcast.net> Check it out ~ this works too ~ and the reverse-side is neat also http://www.antiquark.com/sliderule/sim/n909es/virtual-n909-es.html Cheers, Jan K1ND From JimMiller at STL-OnLine.Net Fri Aug 15 22:35:08 2014 From: JimMiller at STL-OnLine.Net (Jim Miller) Date: Fri, 15 Aug 2014 21:35:08 -0500 Subject: [Elecraft] Mirage B215 amp for sale - 2 in 150 out Message-ID: <003301cfb8fa$b2344ae0$169ce0a0$@STL-OnLine.Net> Who wants one - email me direct - have one I was about to list for sale.

Oo, yes please, Wayne, I like the idea of using a K3/KX3 without having to rely on a computer being used and hence adding to the ever increasing ambient noise level. But I thought SSTV was already on the long term wish list as it was discussed several years ago? I would be pleased to alpha test this when you're ready.

I've just put together a KPA-500 linear amplifier kit and everything seemed to work fine until I switched from standby to operate when I get a 270v ERR message, which needs a hard reset. The 60v line is present (68.5v) and the interlock works as it should do. I've checked and there is no 270v line present for the PA T/R switch reverse biasing - grey wire on PSU. That is until the grey wire carrying the 270v line from the PSU, which connects to P2 on the PA board is unplugged and then I can see the required +270v. Clearly the PSU is working. As soon as I reconnect the grey wire to P2, the volts disappear and R17 on the PSU board starts to get hot. I've found a circuit diagram for the KPA-500 on the WB4KDI web site: http://www.qsl.net/wb4kdi/Elecraft/index.html Here it shows R17 in the 270v bias circuitry as a 10K rated at 1W. However, R17 in my PSU is actually a marked 1K rated at 1W (measures 998 ohms) Is this the problem? Wrong resistor fitted in the factory? I dunno whether this actually is the problem or whether Elecraft have changed the circuitry since that earlier circuit diagram referenced above was made available and the fault is elsewhere. Sadly, there was no circuit diagram in the handbook provided with the KPA-500. Any thoughts please?

The RF sensor was prior to the svga board and as such it is reasonable to expect that it will be that way. Not all P3's are sold with the svga and i imagine sales of the rf sensor could be higher if that option was not required. The cost of the sensor will be a significant amount i imagine but we just have to wait and see. My concern is just how meaningful the display will be so will wait for the big announcement.

Just installed the KX3-2M but had a hair-pulling time getting it enabled. Turns out the Rev A3 (8-15-2014) instructions are out of order. On page 3, the 5th bullet has the user edit the BND MAP to enable 144. The problem is that 144 does not show up until the transverter is enabled on bullets 8 - 13. The 5th bullet needs to be moved after transverter settings, and after a power cycle. Bullet 6 is a duplicate of bullet 4 and needs deleting. Several other users had problems, reporting that it worked after several attempts, which makes sense since the transverter would have been enabled on the second attempt to edit the band map.

There's a half dozen or more analog modes, most of what I decoded was one of the Scottie's [there are several].? I suspect that, to be attractive, your software would need to decode the digital burst at the beginning and auto-select the mode like MixW does.

Should you encounter this, just holding the "kHz" button a moment reverted VFOB to 144.xxxxxxx MHz, and VFO A remained the wrong frequency. Using the B>A switch properly loaded 144 MHz into VFO A, and operation was now corrected. Those of you who have the menu item PA ON for use with the KXPA100 when testing the new setup without the KXPA100 connected will not have use of your KX3AT tuner if installed until you turn it off. Now to find out why nobody seems to use the repeaters around here any more; Cell phones appear to be winning out! 73, Gene N9SW Sent previously: I just completed the straightforward install of my new KX3-2M 2-meter module in my KX3 s/n 335 with ATU, encountering no issues. (firmware level at 2.12). The simple configuration setup procedure also went smoothly. After powering off and on as instructed, however, instead of a new 144 MHz band, I have now added a band which VFOA says is 22.0 MHz, and VFOB is showing 44.0 MHz instead of 144.0. Restored the various settings as they were before the install, powered off and on again, then redid the 2 meter settings, with the same results. Has anybody else experienced this, or have suggestions? 73, Gene N9SW From dave at nk7z.net Sun Aug 17 12:56:26 2014 From: dave at nk7z.net (David Cole) Date: Sun, 17 Aug 2014 09:56:26 -0700 Subject: [Elecraft] Slow-scan TV (SSTV) display on the P3 and PX3?

There is a big difference between CW, RTTY and PSK31 decode when one can transmit paddle CW/RTTY/PSK and SSTV decode when there is no matching SSTV generation capability. There are a lot more UI and control improvements (separate VOX for SSB and digital, separate default bandwidth for DATA A and AFSK A/FSK D, ability to set a default "Norm" bandwidth for each mode other than the roofing filter bandwidth, etc.) as well as improvements to the notch (place manual notch outside the AGC loop) and noise blanker. 73, ...

I have now resolved the fault that was causing the +270v T/R bias line to be shorted and the "270v ERR" hard fault to show. As several others have discovered with the same fault, the problem was C2, a faulty 0.01uF, 500v, 1206 SMD capacitor; part of the T/R circuitry on the PA board, which was going short circuit when the 270v was applied. The capacitor tested OK without volts applied, but on inspection with a magnifier had a hairline crack at one end and fell apart when I removed it. C2 is easy to get at once the PA assembly is removed for inspection and repair, but of course much of the KPA-500 has to be disassembled to do so. Anyway, I have now replaced the faulty capacitor with a good one and all is working correctly. I assume that R17 has been reduced in value from 10K to 1K on later versions of the KPA-500 and that value is correct. Apparently, from comments received from several other folks, this is not an unusual fault and Elecraft are well aware of the problem. Luckily, I was able to fix the fault here in my workshop. Others have not been so lucky and have had to return the PA assembly to Elecraft for repair. Now to test the newly built KPA-500 with my K3 and do the final adjustments. I'm keeping fingers crossed there are no more nasty surprises. Thanks everyone for their comments and help with this particular KPA-500 fault.

I work a lot of JT65 on 6M, and there are several strong signals (not of overload magnitude) near me. The NB DOES create artifacts that result in multiple decodes, and corresponding stuff that is quite visible in the P3 display, and that is not visible when the K3 NB is off. 73, Jim K9YC On Fri,8/15/2014 2:35 PM, Joe Subich, W4TV wrote: > >> I often study the screen of my P3, which DOES show reduction of noise >> when the wider NB is active. 2-4 dB is typical for the types of noise >> for which it is effective. > > 2 - 4 dB may be due to upsetting the impedance at the IF feed but given > the circuit topology it is not possible for the NB to provide effective > blanking to the P3 with the noise gate *after* the IF pick-off point. > > 73, > > ...

I also connected a dummy load directly to the KX3, same problem. Using the tune button and by-passing the ATU get SWR readings of 99.9 with dummy load on freqs below 5 Mhz? So it probably is not the ATU. When installing the 2 meter module I had to move the inductors, the 2 mtr antenna connector was touching one inductor, fit was very tight. I have rechecked 2 meter module install nothing obvious.

The module seems to work fine but now the ATU in the KX3 will not tune up on 80 or 160. Best SWR KX3 shows is about 10-1 on freqs I have used many times before where ATU used to get near 1.1. I used same cables, antenna, with different tuner and HF rig, two different antennas, tune up fine as before.

I tend to run 20 kHz on phone and 7 to 10 kHz on CW as I'm mostly interested in the signal I'm receiving and the adjaceant signals. I typically do not change the spans when I change bands, only when changing modes. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

References: Message-ID: Measure the amps you are charging them with, and charge them at C/10, where C is the capacity of them. Say you have 1200mA NiMh batteries, charge them at 120mA overnight. You can charge up to C/1, but be careful not to overheat the cells. You should be able to hold them in your hand. Then put some sort of a load on the batteries, and measure the voltage on each individual cell. As they discharge, the weakest cell will drop in voltage faster than the rest.

DATA is not a single mode - it is only a "folder name" for a collection of different data sub-modes. Many of those sub-modes require quite different settings for the transceiver bandwidth and center frequency; and that is equally true about the optimum bandwidths for a visual display. At present the K3 has... let's call it an "oversight"... in the way that it memorizes data sub-modes. It correctly memorizes the last-used data sub-mode on each band, but not the bandwidth setting appropriate to that sub-mode. Instead, the bandwidth settings for *all* data sub-modes on *all* bands are overwritten by the settings for whichever sub-mode was most recently used on *any* band. This is often quite inappropriate, and inconvenient for anyone whose interests cover a range of data sub-modes. That problem needs to be fixed in the K3/KX3 firmware before moving on to upgrade to automate the display settings of the P3 and the PX3. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Joe >Subich, W4TV >Sent: 18 August 2014 13:17 >To: Wayne Burdick >Cc: elecraft at mailman.qth.net >Subject: Re: [Elecraft] Slow-scan TV (SSTV) display on the P3 and PX3? > > >On 2014-08-18 1:10 AM, Wayne Burdick wrote: > > We're considering per-mode as well, > >I agree that per mode is more valuable than per band.

Agreed - and one of those user interface issues to which I referred earlier in this thread. DATA A and AFSK A/FSK D need separate default bandwidth (2.8 or 4 KHz for DATA A, 500 Hz for AFSK A/FSK D) and the last used BW/FC values need to be stored per sub-mode/band. 73, ...

The KNB3 *is* downstream of the pick-off point for the P3. But in the presence of very strong signals and with the KNB3 set to a long gate time, some of the gating artifacts could in theory back-propagate to the pick-off point, affecting the P3. Normally this effect would be highly suppressed because of the low impedance of the driving stage (the mixer post-amp).

With a short passive whip, the KX3 is far behind the Grundig, because even strong station is barely heard from KX3. However, an active antenna makes the KX3 much better, but still not significantly better than the little Grundig. In fact, this comparison is not a fair game for both rigs. The Grundig has a built in amplifier to work with the telescopic antenna, while the KX3 is not designed for that purpose. A safe conclusion would be that the KX3 is a little deaf using short whips, and the Grundig is a descent shortwave receiver too. 73, AC9FU, Chris 2014-08-19 0:54 GMT+08:00 George Fritkin : > Wouldn't the fact that the bandwidth is much more narrow in the KX3 than > your typical SW RX.

Data guys want mo? data stuff and changes to existing features. Moon bounce weak signal guys want something else. Something doesn?t work right for one mode used by a few. CW guys will want something else. A few don?t like the size of the cabinet. And then there?s the location of the notch. Etc. Everyone seems to have a personal want list depending on their personal interest and real or perceived faults in the radio. Bill (if your name is Bill, don?t take it personally, please) wants something done one way, Joe wants it done some other way, and John doesn?t like either one. No matter what is done, someone will be unhappy or find yet one more ?inexcusable? design choice or engineering ?error? and find a few other people on the list who agree with him, as we split into armed camps over some issue or other that will prevent the apparently unforgivable requirement to actually turn a knob or make a conscious decision to change a parameter. Why would SSTV decode on the P3 be ?off track?? It would be an interesting feature, in any case. If someone suggests something, 20 people chime in with ?that?s nonsense?, followed immediately with their own ?essentials? or gripe list which likely at least in part is just as much nonsense to others. Design by committee doesn?t always yield a very good design. One more curmudgeonly opinion, from someone who is simply happy that the whole thing works and is blessed with appendages expressly designed to manipulate buttons and knobs ? ;) Grant NQ5T On Aug 18, 2014, at 12:34 PM, david Moes wrote: > add me into the per mode group. and auto reference level would be cool > From jim at audiosystemsgroup.com Mon Aug 18 14:20:17 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 18 Aug 2014 11:20:17 -0700 Subject: [Elecraft] No thanks to SSTV on P3, let's get back on track.

I also put a scope on pin one and pin 4 of U1, the Receiver Mixer. The relative voltage was 3x higher on pin 1 than on pin 4. I would at least have expected gain instead. Any comments appreciated. 73 Les KE7SLX From w3fpr at embarqmail.com Mon Aug 18 18:00:19 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Mon, 18 Aug 2014 18:00:19 -0400 Subject: [Elecraft] K1 Receiver Sensitivity Issue. In-Reply-To: References: Message-ID: <53F27773.2000707@embarqmail.com> Les, Yes, the NE612 should show plenty of gain. When it does not, the usual reason is little or no oscillator signal to pin 6. The Pre-mixer Bandpass filter must be aligned before you will get much of a signal at U1 pin 6. Since you have a 'scope (hopefully with a 10X probe), I will give you an alternate method of tuning the Pre-Mixer Bandpass filter. Since you have the 4 band board, you must follow the proper band order - adjust 15 (or 17) meters before adjusting 20 meters, and likewise adjust 30 meters before 40 meters. Make a check before starting - align all the slots in the trimmer capacitors parallel with the long edge of the band board. Then check the activity of the crystal for each band - put your probe on band board P1 pin 4 and not the amplitude of the signal as you switch through the bands - you should have greater than 200 mV peak to peak. The position of the trimmer slots when tuned should be no more than 30 degrees from the center position if your toroids are correct. Then switch to 15 (or 17) meters, and with your probe on P1 pin 6, adjust the Pre-Mixer trimmer caps for 15 meters for the maximum amplitude. Switch to 30 meters and do the same for that bands trimmers. Do the same for 20 meters and 40 meters. You should be able to get 200 mV peak to peak there on all bands. Remember that your 'scope probe will load the Pre-Mix filter a bit, so the trimmers to the right of the filter will not be at their optimum setting, but it will be enough for receive - you will set the optimum position when you adjust for transmit. You should check to see that the Pre-Mix signal is getting to U1 pin 6 - if it is not, suspect the coax link on the bottom of the board between J9 and J10. Once you have a good signal at U1 pin 6, you should see that the output at pin 4 is much greater than the input at pin 1. 73, Don W3FPR On 8/18/2014 5:20 PM, Les Garwood wrote: > Dear Fellows, > > I Bought a K1 kit at a ham fest several years ago (SN 02197) and recently > finished the receiver section.

Both units have had the temp calibration done to them. When using CW, there is a noticeable drift in the received CW side tone. It has an unsable warble back and forth slowly +/- ~10 HZ or so. Is this the natural drift of the 2M unit I'm seeing here?

I mostly followed your advice--I say mostly because I got diverted when I found a clue. I would still be searching without your insights and expertise, however. I was getting about 150 mv out of pin 4 of u7. I traced it to pins 1and 2 of J6, which was still hot on the scope through the secondary winding of T1 ON THE FILTER BOARD but was dead upon arrival at pin 6 on the return leg. This sent me on a merry chase of testing all the relay solenoids for continuity, and their contact leads. They all checked good so then I leapt at the conclusion that the controller IC was at fault. I tried resetting it to factory default but no apparent change resulted. So, I went back to the scope and finally found the exact dead end: C15 was wrongly mounted. Somehow, I misread the silkscreen hole indicator, I'm embarrassed to say. Anyway, I resoldered it in the right holes and, instantly, robust CW screamed at me. I'm thrilled and humbled.

That is nonsense. There are plenty of tools to easily track issues and feature requests in a way that is no burden on your time.

It will change that. Products live and die by the feedback customers give to the company. With no public issue tracking service offered by Elecraft of course it is going to look like a black box when in reality the lack of transparency for change requests is hurting the product. People are making their own 3rd party products for Elecraft (for the KX3 for example) because "crystal-ball-gazing, head-counting, arm-wrestling-over-a-beer, and a healthy dose of what-we-have-time-for" doesn't scale.

I think I bought mine it was in a sale and was even less expensive too. It has a waterproof cover too, though I have never used it. http://www.7dayshop.com/products/7dayshop-canvas-photo-messenger-shoulder-bag-DS-014 Being into photography as well as amateur radio, I have a collection of very expensive camera bags as I try to find the ideal one for various cameras and lenses, but I must say I think the 7dayshop one is as well thought out and protective as those much more expensive bags. 73 David Anderson GM4JJJ > On 19 Aug 2014, at 02:51, Phil Wheeler wrote: > > I use a LowePro Nova 170 AW.

Elecraft would still control software updates including open source contributions. The Internet is built on open source protocols and software and ham radio manufacturers would be wise to follow suit. This is a low risk, high gain move with nearly zero switching cost.

I have excellent hearing and I have K3 #5102 and while it's a rig with outstanding capabilities, the fan noise has always bothered me. My K3 has the Utec fans and even on low speed, there's something about the quality of the fan noise that's bothersome, quite apart from the volume, which I find distracting even through over-ear headphones. Early on, I wondered if I had faulty fans from a bad batch. I replaced them with a new pair from Elecraft, but they were as noisy as the originals. Well, today the problem is fixed. Inspired by Harry's posts on the topic, I swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes. The difference took me by surprise. They are very, very quiet even in a silent room and I can't hear them through the headphones at all. The quality of the sound is softer somehow - just like moving air and without mechanical overtones! I worked CW for an hour tonight to get the rig warm and these fans have transformed the experience. I'm very pleased.

With regard to Elecraft "open-sourcing" their firmware.... don't count on it. Especially if you like to have the current level of support. Let's see how Ten Tec fares with their open source rig. As far as I can see, Elecraft is quite responsive to feature requests and bug fixes. People often point to a -lack- of response from other manufacturers... including fixing -known- issues. They just continue to make the same broken products. In the end, things have been working quite well for Elecraft from a business perspective. I doubt there would be any desire to change anything that "isn't broken" from their perspective, and from the perspective of most customers. 73 de Ray K2ULR KX3 #211 On Aug 19, 2014, at 3:33 AM, Andrew White wrote: >> >> >> >> to quote Wayne from 7/10/2014 7:55 PM >> >> >> Hi all, >> >> Our firmware task lists are sorted by priority.

Once upon a time, this was the argument behind all open source projects -- everyone is looking at the code, therefore every security hole will be seen as part of this massively parallel but highly informal code review. If you want to see the truth, look at all of the websites out there that have been hacked because they're running some kind of open source framework. Those sites usually used someone's open source upload component, but no one did a code-review for security issues before adopting the component(s) in question. That's because people do not read code for pleasure, nor do they find great joy in smashing bugs. They just use what they need, and do enough to get what they want. Closed-source isn't the solution, but neither is open-source. 73 -- Lynn From elecraft at mailman.qth.net Tue Aug 19 12:18:41 2014 From: elecraft at mailman.qth.net (Harry Yingst via Elecraft) Date: Tue, 19 Aug 2014 09:18:41 -0700 Subject: [Elecraft] [K3] Fan Replacement In-Reply-To: <4516871C-F1F0-465F-9B36-ACC31C5A8543@netspace.net.au> References: <4516871C-F1F0-465F-9B36-ACC31C5A8543@netspace.net.au> Message-ID: <1408465121.60473.YahooMailNeo@web125901.mail.ne1.yahoo.com> Thank you That is the same I found I hear the air move but not the fans For me it really improved my listening pleasure ________________________________ From: Dr John H Farmer To: "elecraft at mailman.qth.net" Sent: Tuesday, August 19, 2014 7:02 AM Subject: Re: [Elecraft] [K3] Fan Replacement Hello Group, I just want to share my experience in case it's of interest to others. I have excellent hearing and I have K3 #5102 and while it's a rig with outstanding capabilities, the fan noise has always bothered me. My K3 has the Utec fans and even on low speed, there's something about the quality of the fan noise that's bothersome, quite apart from the volume, which I find distracting even through over-ear headphones. Early on, I wondered if I had faulty fans from a bad batch. I replaced them with a new pair from Elecraft, but they were as noisy as the originals. Well, today the problem is fixed. Inspired by Harry's posts on the topic, I swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes.? The difference took me by surprise.? They are very, very quiet even in a silent room and I can't hear them through the headphones at all.

I am a user, not a programmer, so I have a different perspective. The "support" is through forums, and if you are not sufficiently skilled in "geek speak", there is danger that you will be flamed for asking a question, or you may receive an answer that is so thoroughly steeped in "geek speak" that it is useless for you. Been there done that. Besides you have to constantly monitor the forum to see if anyone has provided an answer to your question. If a user has a problem with an Elecraft product and contacts Elecraft support, you can expect to discuss your situation with someone who is both responsive and knowledgeable and will work with you to resolve the issue or present it to engineering. I highly suspect that would not be the case if the firmware were open-source. Open-source is 'nice' for programmers who want to implement their pet additions, but for the majority of users, open-source is not the way to go IMHO. 73, Don W3FPR > And yet open-source software has been shown to be very successful.

Not to mention, of course, the possibility of somebody burying a small chunk of malicious code. I don't think your proposal represents low risk at all, particularly to Elecraft, but also to that portion of the user base who even stumble over officially released firmware upgrades and would now have to sort out multiple options competing for the same limited number of bytes of code, and in ways that may not be compatible. Elecraft's brand image hangs on EVERYTHING associated with their products ... not just the things they create themselves. If somebody contributes a modification that adds a feature but harms something else, the rig bears the brunt of the loss in reputation.

You should very carefully make sure that the actual peak power and the steady CW power are the same. Make sure that all the manual's calibrations have been run. In order to run right, the firmware needs to know a small pile of things about your particular K3 to make performance standard. "Recently" does not give me warm fuzzies about being adjusted to spec. I have found that sometimes doing a firmware update will unglue some of the stored data in the K3, both calibration and others, despite Elecraft's protestations that shouldn't happen. Doesn't hurt to rerun the ENTIRE set of calibration exercises every couple of years. Not with every firmware update for sure, but whenever an update is followed by some previously unnoticed quirkiness I'll run them. That way I'm on the clean side of things if I report a quirk to be related to an update. If the quirk was cleaned up by a calibration, one can be assured that Big E will never be able to duplicate it and figure out what was going on if I reported it without recalibration. I really don't want to waste any of their time. They're more interesting when they're working on their projects. 73, Guy K2AV On Tue, Aug 19, 2014 at 3:33 PM, Fred Townsend wrote: > > Mark I have not seen your problem so I tend to discount your explanation.

Elecraft provides programming info for those who want to write programs for their products (Software). If someone wants to write programs for Elecraft equipment and make it Open Source, it is permitted. On the other hand, I don't know of many manufacturers that provide Open Source FIRMWARE. While some manufacturers provide Firmware upgrades (like Elecraft), I'm not aware of any that publish source code for their firmware. Bigger computer vendors do provide firmware updates to their hardware but I've never seen one provide Source Code (Open Source). I come from a Unix background and much Open Source Software is available (and for Linux variants). But not at the hardware level. No major corporation would implement software that they can't support and there are too many variables to use Open Source for every application.

I had a look, but couldn't find a Noctua fan with the same specs as the stock Sunon which came with my KPA500. I did find that the fan noise on the KPA500 was reduced by mounting it on a silicone gasket and I'm happy with the improvement it made, so will leave it at that. Besides, there's much greater airflow through the KPA500 and I never expected it to be quiet, I just wanted to reduce the mechanical element to the noise. The gasket approach didn't help at all with the K3 fan noise, FWIW. If anyone explores the KPA500 fan situation further, I'd love to hear.

I moved the internal antenna cable and KX3 is working fine now. This time I was very careful when putting the case back on. I think the case moved the antenna cable out of position as shown on page 27, figure 21 of 2 mtr module instructions. Once antenna cable was not touching or over the toroidal inductor no problems with SWR. Thanks Jeff for the tip and all others who responded. 73 Emory WM3M -----Original Message----- From: Jeff Herr Sent: Monday, August 18, 2014 8:22 AM To: ejkkjh at gmail.com Subject: RE: [Elecraft] Fw: KX3 2 mtr ATU problem I saw your post but I thought someone better qualified would respond. I had a similar problem. I went back into the unit to find the antenna cable had shifted and was right over the top of one of the atu toroids. see fig 23 in the assy manual. i set it back to pointing direct to the card edge, closed it up re-tested and was back in business.

So, it would be difficult to upgrade the firmware on the K2DSP. Also, the firmware for the user interface is not open source, which limits the scope of adding features. These days, if you want to experiment with DSP algorithms, it is probably more convenient to do prototyping on a general-purpose PC with sound card. 73, Matt VK2RQ > On 20 Aug 2014, at 4:12 am, Hisashi T Fujinaka wrote: > >> On Tue, 19 Aug 2014, Wayne Burdick wrote: >> >> Lyle (KK7P) reminded me that we did do one experiment in community-sourced firmware: the KDSP2 DSP option for the K2.

Does it have the rated capacity the original has? It is rated to operate at "low" speed without heating up or some other malady? Is the construction such that the lifetime is more than a few months? Is the current draw similar to the original? Assuming the voltage is such that it will not catch fire if it gets into high speed mode of course.

I have excellent hearing and I have K3 #5102 and while it's a rig with outstanding capabilities, the fan noise has always bothered me. My K3 has the Utec fans and even on low speed, there's something about the quality of the fan noise that's bothersome, quite apart from the volume, which I find distracting even through over-ear headphones. Early on, I wondered if I had faulty fans from a bad batch. I replaced them with a new pair from Elecraft, but they were as noisy as the originals. Well, today the problem is fixed. Inspired by Harry's posts on the topic, I swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes.? The difference took me by surprise.? They are very, very quiet even in a silent room and I can't hear them through the headphones at all. The quality of the sound is softer somehow - just like moving air and without mechanical overtones! I worked CW for an hour tonight to get the rig warm and these fans have transformed the experience.? I'm very pleased. Thanks Harry. 73, John VK7JB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 hlyingst at yahoo.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 jimmiller at stl-online.net From k5oai.sam at gmail.com Tue Aug 19 23:24:20 2014 From: k5oai.sam at gmail.com (Sam Morgan) Date: Tue, 19 Aug 2014 22:24:20 -0500 Subject: [Elecraft] FW: [K3] Fan Replacement - fan rating In-Reply-To: <002b01cfbc23$b042f890$10c8e9b0$@STL-OnLine.Net> References: <002b01cfbc23$b042f890$10c8e9b0$@STL-OnLine.Net> Message-ID: <53F414E4.3060308@gmail.com> as previously stated: New Fan: Noctua NF-A6x25 FLX Airflow: 17CFM (29.2 m3h converted to cfm) Noise: 19.3db Speed: 3000 RPM (at 12 v) Static Pressure: 2.18 mm Cutent: 120 mA (.12 A) Original Fan: UTEC AT6015L-12L2B-ND2 Airflow: 15.4 cmf at 24.8db Noise: 24.8 Speed: 3000 RPM (at 12v) Static Pressure: 2.21mm Current: 100 mA reference: http://www.mail-archive.com/elecraft at mailman.qth.net/msg172610.html On 8/19/2014 10:06 PM, Jim Miller wrote: > Did anyone bother to verify the rating of this fan vs. the factory one? > > Does it have the rated capacity the original has? > It is rated to operate at "low" speed without heating up or some other > malady? > Is the construction such that the lifetime is more than a few months? > Is the current draw similar to the original? > Assuming the voltage is such that it will not catch fire if it gets into > high speed mode of course. > > My fan is fine with me but maybe I should be happy that my hearing is 10db > down from 0-1500 and then after 1700 I am virtually deaf at 50db down. > > Makes a fairly good wife filter. > > 73, Jim KG0KP > -- GB & 73 K5OAI Sam Morgan From zendoc at netspace.net.au Wed Aug 20 00:51:13 2014 From: zendoc at netspace.net.au (Dr John Farmer) Date: Wed, 20 Aug 2014 14:51:13 +1000 Subject: [Elecraft] [K3] Fan Replacement In-Reply-To: <1408465190.54341.YahooMailNeo@web125905.mail.ne1.yahoo.com> References: <88EF983C-F01B-4686-BFE9-AE1D6C6F418E@netspace.net.au> <1408374287.38843.YahooMailNeo@web125906.mail.ne1.yahoo.com> <14290821-F822-4B68-84C1-E9BBF89A8F91@netspace.net.au> <1408407391.74916.YahooMailNeo@web125905.mail.ne1.yahoo.com> <000001cfbb53$3ea84ad0$bbf8e070$@netspace.net.au> <1408465190.54341.YahooMailNeo@web125905.mail.ne1.yahoo.com> Message-ID: Yes Jim, the published specs of the Noctua and Utec fans have been presented in this thread.

Your usb-serial adaptor probably will be recogniced as /dev/ttyUSB0, while your Windows-Software running under wine only can handle COMx. So you need to tell wine what device it should use for serial communications. You can do this by linking the linux-device to the windows device. Open a console and type: ls /dev/ttyUSB* You should see a reply like this: /dev/ttyUSBx where x is probably 0 (zero). Now, assuming the x was 0 (zero), type (case-sensitive!) or simply copy and paste: ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 If you type correct, this will put a file named com1 in /home/yourusername/.wine/dosdevices where /.wine is a hidden directory. Check if the file is there by typing ls ~/.wine/dosdevices Amongst a number of drive-letters, you should find a file named com1 (This step might or might not be neccessary: (Then log out and back in. If you don't know how to log out/in, simply (reboot. Now run your application under wine. Advise it to use com1. I expect this to work, but if it doesn't , you probably need to set some permissions.

I'm having troubles with transmitting PSK31. Normal setup which worked perfectly for several years. Setup: K3/100, HRD/DM780, separate sound card line-in/line-out to K3 line-out/line-in. PTT control by HRD, K3 VOX ON and K3 MIC SELECT on LINE-IN. For several day I can't make a QSO. I receive perfectly but when I call, no answer. Also calling CQ on 15m with the band wide open, no answer. The K3 is putting out about 30 watts, antenna (yagi) and SWR are perfect. I also hear the normal sound of transmitting from K3's monitor. It look like I'm receiving and transmitting on different frequencies. In HRD the offset is zero (0). Using USB or DATA A makes no difference. Another thing I noticed; when HRD is finishing a CQ macro, K3's transmitting output drops to zero but PTT stays active. Pressing the XMIT button twice will release PTT and K3 go on receive again. K3 VOX DELAY is zero. Are there any config settings I might messed up? Or hardware issues? I reinstalled HRD/DM780. No effect.

I think Elecraft is wise to keep sw development "in house". So a suggestion that would be a compromise would be a small programmer pool (vetted experts) that could summit sw solutions to many of the "wants". That might save the staff some time or provide a wider variety of code to chose from. But sw (firmware) should stay under the Elecraft control and approval. I, like Don, am a sw user. I am not interested in "doing sw". I have other interests that I want to focus on. Any9one remember the sw chaos in the early days of packet? Finally a standard was developed.

Been there done that. Besides you have to constantly monitor the forum to see if anyone has provided an answer to your question. If a user has a problem with an Elecraft product and contacts Elecraft support, you can expect to discuss your situation with someone who is both responsive and knowledgeable and will work with you to resolve the issue or present it to engineering. I highly suspect that would not be the case if the firmware were open-source.

The users that weren't affected were those heavy-duty software companies who developed their own in-house security layers, and kept the code to themselves. Many software developers have found that it is to their economic advantage to make at least part of their code open-source, and many others have found it to their advantage to make their code proprietary. The choice depends on the developer's marketing plan, the target audience, and the other surrounding economic conditions. In Elecraft's case, making any code open-source makes zero sense, economic or otherwise. The quality of any code is determined by the skill of those working on it, not by whether you can find it on Github.

I think you will see even more heating in transmit. That's why an oscillator with a low temperature coefficient is important. 73 Fred, AE6QL -----Original Message----- >From: on4iq >Sent: Aug 20, 2014 11:50 AM >To: elecraft at mailman.qth.net >Subject: [Elecraft] KX3 oscillator temperature > >I recently started extensive temperature testing on the KX3 to get more data >on dissipation and stability. >For starters stability in RX.

Kudos to Elecraft for doing this way out of warranty free replacement (ser# 82) in the first place, but also to USPS for delivering regular mail in 2 days. The USPS, often unfairly maligned, is really an excellent service. It installed easily after I was first stumped by the fact that the 5/64" Allen key was missing from my inch set, but fortunately the 2mm one from the metric set did the job. 5/64" = 1.98mm. Now to hunt for the missing Allen key. First move: Ask the XYL where it might be. She's a real super finder. I had a close look at the removed knob and methinks that it would not eventually fall apart as the concentric knobs tended to do when they cracked. I still have spares for these after Elecraft sent me a complete set of replacements for all 4 many years ago (free of charge of course). ab2tc - Knut Dave Wank wrote > I received a new VFO B knob within 2 days after asking for it.That's great > service from Elecraft----Thank you Lisa Jones and anyone else who is > involved in shipping the knob to me that fast!-----Dave NK8A > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto: > Elecraft at .qth > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to > lists+1215531472858-365791 at .nabble -- View this message in context: http://elecraft.365791.n2.nabble.com/VFO-B-knob-tp7592397p7592412.html Sent from the Elecraft mailing list archive at Nabble.com.

Most everyone solves the problem by putting an 100 ohm resistor across the fan thermal switch, which causes the fan to run all the time, but still noisy at full power. I didn't want mine running all the time, checked out the specs of the Sunon fan, it sells for $2.55 at Digikey, and is rated for 12 volts. My power supply is running at 13.9, almost two volts high for the fan. I inserted a 20 ohm resistor in series out of the thermal switch, fan runs at about 12 volts and is much quieter. I may replace it with one of the Noctua fans and see if that works better. The Noctua 80mm fan is also rated at 12 volts so I plan to leave the resistor in place for now. More to come.

However I'm not surprised that there were no takers. Assembly languages coding for DSPs is well outside the main open source community (although there probably is a sub-community for it). Most people would be into C for desktops or assembly for PICs. The other problem, at least in the UK, is that sourcing DSP chips in small quantities is likely to be difficult, and I suspect the programmers (hardware) are expensive, especially compared with those for low volume programming of the PIC. In practice I've not found a strong enough need to justify adding audio filtering, anyway. -- David Woolley Owner K2 06123 On 19/08/14 19:00, Wayne Burdick wrote: > Lyle (KK7P) reminded me that we did do one experiment in community-sourced firmware: the KDSP2 DSP option for the K2.

Think of a car's engine: it uses less fuel at idle than at high RPMs. So more power being used in the synthesizer is going to make it hotter, since any electronic component is not 100% efficient and unused energy is spent as heat. 73 de Ray K2ULR On Aug 20, 2014, at 7:32 PM, Wayne Burdick wrote: > The synthesizer I.C.'s current drain, and thus its operating > temperature, vary in direct proportion to operating frequency. > > 73, > Wayne > N6KR > > On Aug 20, 2014, at 11:50 AM, on4iq wrote: > >> I recently started extensive temperature testing on the KX3 to get >> more data >> on dissipation and stability. >> For starters stability in RX.

(I used a Meanwell NET-35B). It outputs a 10MHz sine wave (which plugs into the K3EXREF) as well as 1pps logic signal. Trimble also makes/made an active antenna, which I also found on E-Bay, which is a small square about 2 in/5 cm square and has an internal preamp powered by +5V supplied on the Thunderbolt's antenna jack. I've been running one for about a year now, and it maintains the 10MHz to within about 30 parts per trillion, depending on how many satellites are regularly visible - I usually "see" 8 or 9 in south Florida and 5-6 in the mountains of western North Carolina.

It was cured using the suggestion from the list here. After an hour of tuning around and sporadically trying to get the local repeater to come up, a problem started. Unit seemed to transmit OK on all bands and all modes. PROBLEM: The HI CUR warning started to come on 3 - 5 minutes after the rig has been turned on and is RECEIVING fine then the rig beeps 3 times and turns itself off. PLEASE NOTE: This only happens in RECEIVE - all bands and modes including 2M. The rig will tune and transmit. Observations: Volume is set at about 5 Current is at 0.212 at V0 goes to about 0.230 A with the volume at 12 or so. Voltage is at 13.7 and rock solid PA.I reads 27C OSC reads 32C The heatsink area at back of the frame is cool to lukewarm. The SUB indicator was flashing, but turning off the SUB does not change the self shutdown behavior. What is it that is done during the KX3-2M installation that could have triggered this? Is it something I could have accidentally tweaked in the settings or is this going to trigger a visit to back to Elecraft?

Several people responded here and were very helpful but it was Martin DM4IM who sent me this which was easy to read, understand and accomplish: Hello Bill, try this: Linux handles serial devices different from windows. Your usb-serial adaptor probably will be recogniced as /dev/ttyUSB0, while your Windows-Software running under wine only can handle COMx. So you need to tell wine what device it should use for serial communications. You can do this by linking the linux-device to the windows device. Open a console and type: ls /dev/ttyUSB* You should see a reply like this: /dev/ttyUSBx where x is probably 0 (zero). Now, assuming the x was 0 (zero), type (case-sensitive!) or simply copy and paste: ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 If you type correct, this will put a file named com1 in /home/yourusername/.wine/dosdevices where /.wine is a hidden directory. Check if the file is there by typing ls ~/.wine/dosdevices Amongst a number of drive-letters, you should find a file named com1 (This step might or might not be neccessary: (Then log out and back in. If you don't know how to log out/in, simply (reboot. Now run your application under wine. Advise it to use com1. I expect this to work, but if it doesn't , you probably need to set some permissions.

Lost reception when transmitter stage completed. Message-ID: Dear Fellows, I just finished construction of my K1. The receiver stage worked perfectly until I finished the transmitter stage. I still get audio hiss and volume but no signal on any band, AGC on or off, attenuator on or off. All the voltages and resistances check out except the anode of D9, according to the manual, is supposed to be > 100k. I'm sure this is an error, however, since the DC path to ground from that point goes through three resistors and a choke totalling only about a couple K, which is what I measure. I still get rf out of the VFO, and can trace it through the filter board, J6, at pins 1,2 and 6, with my scope. However, there is no trace of signal rf from the antenna on pins 1 or 8 of J7. I have no rf at the attenuator relay either, at pin 3, or any other. I can't quite figure out yet how the TR switch circuit works (or doesn't perhaps) so it's hard to troubleshoot if it is the problem or not. Needing the filter board in place makes trouble shooting all the harder too. I wish I had a layout view showing the bottom of the rf board to help. As always, any comments welcome and appreciated. 73 Les KE7SLX From w3fpr at embarqmail.com Fri Aug 22 14:04:36 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Fri, 22 Aug 2014 14:04:36 -0400 Subject: [Elecraft] K1 Issue.

If so, is that signal large enough to register on what you are using to determine signal or no signal ('scope with 10X probe or RF Probe)? Do you have the jumper installed in J2 of the band board? Turn the signal generator off, then on while observing the level at band board J8 pin 8 - you should see a rise in the RF being measured. If not, the signal level is too low to register on your measurement device. The Signal Tracing section starting on page 5 of the K1 manual appendix gives you an orderly sequence for troubleshooting. Where does the signal level drop below the expected level? That point is just past the point of failure. 73, Don W3FPR On 8/22/2014 1:03 PM, Les Garwood wrote: > Dear Fellows, > > I just finished construction of my K1.

The manual calls for this to be greater than *100* ohms, not *100,000* ohms. A kit sold for 14 years is unlikely to have incorrect test point standards. :-) >I wish I had a layout view showing the bottom of the rf board to help. I have wished (for 14 years) for such PCB trace layouts. They are very appropriate for *ALL* kits. For some reason that has never been coherently explained, Elecraft has never supplied them.

You really need 1.4 volts (or whatever is specified in the procedure) of RF input. I suggest you build the simple oscillator shown in the Signal Tracing appendix of the manual. It has good output for that purpose. The crystal should be at a frequency within your tuning range. 73, Don W3FPR On 8/22/2014 3:07 PM, Les Garwood wrote: > Thanks again, Don. > I've been using Elecraft's signal injector; you may know it puts out 50 > micro volts on the high setting. > I'll try your suggestions but I think I did part of them already. > BTW, I'm using my Android phone so it's tough to write a lot of detail. > > Les > On Aug 22, 2014 11:05 AM, "Don Wilhelm" wrote: > >> Les, >> >> You did not mention your test gear nor any information about your setup, >> so I have to make some guesses and ask some groundwork questions. >> >> Are you injecting RF from a signal generator to the BNC jack?

Your usb-serial adaptor probably will be recognised as /dev/ttyUSB0, while your Windows-Software running under wine only can handle COMx. So you need to tell wine what device it should use for serial communications. You can do this by linking the linux-device to the windows device. Plug in your serial<>usb adapter, open a terminal and type: ls /dev/ttyUSB* You should see a reply like this: /dev/ttyUSBx where x is a number, probably 0 (zero). Type (case-sensitive!) or simply copy and paste: ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 ln is lima november, not one (1) november This will put a file named com1 in /home/yourusername/.wine/dosdevices where /.wine is a hidden directory. Check if the file is there by typing ls ~/.wine/dosdevices Amongst a number of drive-letters, you should find a file named com1 Now run your application under wine. Advise it to use com1. I expect this to work, but if it doesn't , you probably need to logout and log back in (or simply reboot). If it still doesn't work you probably need to set some permissions. Feel free to ask. This works for me with FTDI as well as with Prolific adapters.

A good DOCXO, double ovenized crystal oscillator, is more than adequate, some even claiming accuracies of 10 parts to the -11th . I have purchased several, through Internet advertisers, for well under $50, including shipping from Chinese surplus dealers. These are usually American or Russian surplus units, that are being resold through these sources. I've had repeatedly good and fast service from them. Some of these advertise on E-Bay. I also have Thunderbird and HP GPS stabilized units, as well as Rubidium standards, that could be used. I find that their bulk, complexity and extra wiring is cumbersome and unnecessary, for even up to and including my 10 GHz operations. On my K3/10, which I use for a lot of my V/U/ uW xvrtr needs, as an IF xcvr, I even mount an OCXO, dead bug style to the inside of the 'blank' rear panel of the K3/10 (with "Goop" adhesive), and run it's output to an SMA feed through connector. I can then either use a SMA jumper cable to connect to the EXREF input, or to a power splitter, to also to be used as a 10MHz reference for my xvrtr(s). This certainly makes a very simple and compact solution.

I say "would" because I haven't done it and won't ever put an Li-Poly-anything *inside* a radio. I had one that I got at the local RC Model shop catch fire while I was in the Spartan Sprint, discharging it. I was able to pull the power plug by the pigtail and fling it over the deck rail onto our gravel driveway.

Message-ID: <4641A5E8-AD0B-4B10-B5E3-049FB7C19964@mac.com> OK, I am not sure if I can describe this simply but I will try but first let me describe the symptoms of the result. I am waiting for a CW Traffic net to get started on 80 meters tonight. Just to make sure everything is hunky dory I give my paddle a two-dit hit so as to make sure SWR is OK and my meter reads the right power level. But, this time, nothing. While I am sitting there pondering what happened then there are two brief dits transmitted. Big delay. About 3 seconds I guess (did not have my watch ready so a guess). So, I did this again, one dot, just one single dot. Nothing. In fact, nothing at all, I waited about 10 seconds. Then, I tried again and one dot comes out after about 2 seconds. So, the symptoms are a delay in the keyer responding to my paddle. I powered down the K3 and started it up again. And this time, all functions work perfectly. Paddle and Keyer are happy with each other. Possible cause... Just before I started this sequence described above, I started the K3 utility and mainly because I wanted to watch how the code translate does with the net participants. I noticed that the K3 utility did not auto-start as usual and when I tried the comms port test it just timed out. Yes, it was the correct port. But, I ignored the K3 utility and then focused on the net which was starting and this is when all the trouble with the delay in the keyer happened. After the net, I stopped the K3 Utility and restarted it and could not reproduce the problem. This time, it came on up just fine without any issues. I am figuring some weird initialization process that got out of sync for the utility but I am not sure what happened to the K3 as this has never happened before. And, I have no idea how to reproduce it but I am curious if anyone else has seen a similar problem where something my cause the firmware to maybe get into some state where the keyer is not getting any cpu time or not responding to interrupts or something resulting in a timing delay and thus the behavior I saw. Curiosity only as everything works fine now. System details: K3 is up to date on all released firmware updates. K3 utility is the latest version. Computer is iMac running OS X (Mavericks version with all latest updates). 73, phil, K7PEH From LA3ZA at nrrl.no Sat Aug 23 03:26:08 2014 From: LA3ZA at nrrl.no (Sverre Holm (LA3ZA)) Date: Sat, 23 Aug 2014 00:26:08 -0700 (PDT) Subject: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters In-Reply-To: <20140822143557.A7B7A42E@sj1-dm103.mta.everyone.net> References: <20140822143557.A7B7A42E@sj1-dm103.mta.everyone.net> Message-ID: <1408778768606-7592461.post@n2.nabble.com> A question regarding the DOCXO, double ovenized crystal oscillator to Chuck, W7CS.

There's no Noctua 30mmx10mm fan. The Evercool fan in the KPA100 runs at 8000rpm. I suspect these smaller fans are inherently noisier. The timbre of the sound they emit in full flight sounds harmonic rich and higher pitched, so it's more noticeable if you have well preserved high frequency auditory acuity :). I use my K2/100 for QRP only, because if I work CW at 20W or more, the fan runs pretty much continuously on Tx. 73, John VK7JB From david at g4dmp.fsnet.co.uk Sat Aug 23 08:08:05 2014 From: david at g4dmp.fsnet.co.uk (David G4DMP) Date: Sat, 23 Aug 2014 13:08:05 +0100 Subject: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters In-Reply-To: <1408778768606-7592461.post@n2.nabble.com> References: <20140822143557.A7B7A42E@sj1-dm103.mta.everyone.net> <1408778768606-7592461.post@n2.nabble.com> Message-ID: Have a look at this, Sverre, it will tell you all you want to know. http://www.ve2azx.net/technical/MV89A-1.pdf 73 de David G4DMP In a recent message, "Sverre Holm (LA3ZA)" writes >A question regarding the DOCXO, double ovenized crystal oscillator to Chuck, >W7CS.

Maybe a large, quiet, external muffin fan lying on top would add enough cooling to prevent it from running? 73 de dave ab9ca/4 On 8/23/14 6:31 AM, John Farmer wrote: > Hi Sverre, > > > > I did have a look at this but discovered that the options for alternative > 30mm fans are limited compared with larger sized case fans.

You might want to check a couple things. First, connect an external wattmeter and monitor the actual output - set the power control at 50 watts and see how much power you actually have on CW keydown. If it is much higher (greater than 100 watts), you have a problem with the KPA100 wattmeter. Continued operation with that condition present will cause your base K2 PA transistors to be stressed and will fail sometime soon. Even if you operate with the power knob set below 11 watts, the base K2 PA will still be stressed because the base PA is putting out the maximum power that it can develop - often exceeding 18 watts. Secondly, check the menu setting for CAL TPA - turn power off and wait at least 1/2 hour to allow things to cool to ambient. Then power on and check the setting of CAL TPA - adjust to the ambient temperature in degC if necessary. If you are doing CW (or data modes) with a high transmit to receive ratio, such as during a hot and heavy contest, you can set the fan to LO-HI so it will run at low speed all the time and keep things cooler - that means the times it switches to high speed will be reduced. In normal mode, the fan does not run until the CAL TPA temperature (and the heatsink if CAL TPA is properly calibrated) reaches 40 degC and will turn off when the temperature drops to 36 degC. 73, Don W3FPR On 8/23/2014 7:31 AM, John Farmer wrote: > it's more noticeable if you have well preserved high frequency auditory > acuity :).

That results in a displayed SPACE frequency. Wayne/Lyle, you probably want to offset MARK by Shift when in AFSK REV (and maybe FSK REV).

I believe what is happening is the following (this is the same as what Joe stated, just in different words and using a different PITCH setting): In normal AFSK A, if the PITCH setting is 1445 Hz, the two audio tones are at 1445 Hz Mark and 1615 Hz Space. In AFSK A - REV, the K3's dial still displays a frequency 1445 Hz different from the suppressed carrier frequency (1445 Hz higher in USB vs. 1445 Hz lower in LSB). However, in REV mode the tone that is 1445 Hz away from the suppressed carrier is the Space frequency, not the Mark frequency (i.e. it is the lower of the two frequencies, not the higher). This difference results in a 170 Hz discrepancy between the dial frequency and the actual Mark frequency (the higher of the two frequencies at RF). To put it another way, the K3's dial is reporting the Space (lower) frequency in AFSK A - REV instead of the amateur standard Mark (higher) frequency. If the two tones in normal AFSK A are 1445 Hz Mark and 1615 Hz Space, then in AFSK A - REV the two tones should be 1615 Hz Mark and 1445 Hz Space, and the displayed dial frequency should be 1615 Hz above the suppressed carrier, not 1445 Hz higher. 73, Rich VE3KI VP8NO wrote: Not so sure.

If your 'scope is capable of seeing a 50 MHz signal of 100 mV peak to peak amplitude, yes you should see a good 50 MHz signal from the oscillator Z2. If you have no oscillator there, and you measure 2.7 volts in Z2 pin 4, you may have a bad oscillator - no oscillator, the DDS will not work. If you put a short antenna on the oscillator (Z2 pin 3) you should be able to hear it in a receiver with its "antenna" located a short distance from the added antenna wire. If you indeed do not have an oscillator signal, it is likely a warranty repair and you should contact support at elecraft.com to request an RSA. But make sure the leads of the components mounted in the vicinity do not have solder bridges that is shorting something to ground or another signal line. Such builder errors are not warranty repairs. There is nothing in the "KXB3080 'shortcut' instructions that would interfere with the DDS signal. If you doubt the capability of your scope, use an RF probe to look for the oscillator and/or DDS signal. Measured on an RF Probe you should have at least 70 mV signal at U2 pin 19. Check for a signal at pin 20 too - if you have a signal at pin 20, check your work for solder bridges and other errors - like wrong value components at L4, L5, C39, C51, and C52 - check especially C52 to be sure it is 22pF (220) and not the 220pF (221) capacitor, those marking are difficult to see. 73, Don W3FPR On 8/23/2014 6:50 PM, wa7bme at citlink.net wrote: > Hello All: > My first time to post to this list. > I am building KX1 S/N 2825 and have progressed to page 43 Alignment and Test Part 2 with no problems.

Usually, such a 'scope is useful for determining if there is a signal (assuming the 'scope has adequate vertical sensitivity), but should not be used to measure signal voltage with accuracy above about 10 MHz. 73, Don W3FPR On 8/23/2014 7:47 PM, Fred Townsend wrote: > Ron I have no comments about the KX1.

I know what I'm doing. Pondering the problem further I now believe that AFSK A and AFSK A Rev are similar in operation to CW and CW Rev. Theoretically the decode will (should) stay correctly tuned as the "suppressed carrier" is shifted to suit. The handbook offers no clarification on this. Important note: I run MMTTY in Logger32 which doesn't present the MMTTY UI quite the same as native MMTTY. What I attribute to MMTTY is likely a consequence of the way Logger32 talks to MMTTY. The situation, which actually is of no consequence, is that MMTTY or whatever doesn't understand the frequency manipulations that the K3 performs with respect to VFO display vs mode. The K3 reported frequency via the IF; command is interpreted as the suppressed carrier frequency, which it isn't. ALT is responded to as a sideband change, which it isn't in conventional terms eg switching sidebands in SSB because of additional frequency manipulation in the K3. The consequences are that the RTTY frequency MMTTY displays is incorrect and hence any logging info produced would also be incorrect. This could also be an issue with other data applications. I don't run any others so that is for others to determine. Now in my circumstance as I have said it is of no consequence. Logger32 correctly logs the displayed frequency from the K3 as reported by IF;. I simply ignore any frequency displays that this implementation of MMTTY presents. The reason for trying to get a detailed handle on what was happening was to see if it was possible to somehow, through a radio profile or other means, to bring everything into line without too much effort.

More than likely it is not MMTTY that is doing the display frequency manipulating but the Logger32 Digital interface code. The native MMTTY interface will correct for USB operation. In USB one selects REV in the display and MMTTY will correctly use MARK + Shift for internal frequency calculations. Last time I checked the Logger32 "Display frequency from Radio" option in the Sound Card Data Window as dumb - it did not understand that the K3 and most Yaesu radios could report "Mark" frequency in AFSK - and simply added (AFSK) or subtracted (AFSK-R) MMTTY's MARK frequency from the reported radio frequency. This results in incorrect display for two reasons - 1) with the K3 it is applying an offset that is already applied in the reported frequency, 2) the offset is applied in the wrong direction since Logger32 always assumes AFSK (audio) is USB. Logger32 has had the same brain dead interface for the Sound Card Data Window for perhaps 10 years. It did not work correctly with the Yaesu FT-1000D/MP/MKV and still does not work correctly with the K3. None of this absolves the K3/and P3 of one mistake. The P3 frequency cursor (and K3 frequency display) appear to show the SPACE frequency in AFSK R (and FSK R) - perhaps they are really "reverse" as opposed to "opposite sideband" . 73, ...

I could use a little help tracking down the cause of a weak receiver on my newly built K2/10. All of the test and alignment procedures were satisfactory at each stage of the build. But unfortunately, when I got on the air, the receiver actually seems rather deaf. I do hear a few signals, but rarely do they move the S-meter. After going through the trouble shooting section of the manual with no luck, I decided to use the N0SS, Tom Hammond (SK) ?Cheap ?N Dirty ? signal tracing method to inject a signal at the suggested test points. I found the headphone volume drops off slightly when injecting a signal at the junction of D2 & D3, and almost totally disappears at the junction of D3 &D4. That got me checking the voltages in the T-R switch. I found that I was only getting about 50mV at the junction of D2 and D3 (anodes). I?m also getting 0 volts at the cathode ends of D1 and D2. Backtracking from the anodes of D2 and D3, I get the same 50mV at RFC2. But on the other end of RFC2, I have the full, supplied 8 volts (receive). So I?m thinking that RFC2 is defective, and is the cause of the low switching voltage for the diodes. Does it sound like I?m on the right track?

I used the N-generator for a signal source, and that made it very easy to find out where the problem was originating. A great resource troubleshooting problems!

It is a 200 mA constant charger no smarts other than knowing if the battery voltage too low or too close to the supply voltage. At 200 mA it is difficult to over charge. If the batteries are fully charged and you ask the charger to start a new charge, you can get the error because the difference between the bat voltage and the supply voltage is too small.

If you are subscribed to receive individual emails, make a folder under your inbox named 'Elecraft' or something else you choose. Then create a filter to automatically put all email having [Elecraft] in the subject line into that folder. As far as posting, "reply" goes only to the originator of the post, 'Reply All' goes to the list and the originator. If your email client has a "Reply to List", that will go only to the list. If you do not have that feature and wish to reply only to the list, use "Reply All" and delete the original poster's email from the TO: list in your reply. If I suspect that the poster receives only the digest format, I will always do a "Reply All" if the matter is such that a quick answer is needed. Yes, the N0SS signal tracing method is a good tool to have at your disposal. I use that technique often even though I have several other means of chasing down a problem, including an HP8640B signal generator that is capable of "forcing a strong signal 'down the throat'" of the most obstinate problem situation so I can view the progress through the various stages with my 'scope. One adapts his techniques to the tools available - better tools only mean that one can isolate the problem more quickly, lesser tools can also get to the root of the problem, but it takes more care and time. 73, Don W3FPR On 8/24/2014 3:09 PM, David Doar wrote: > Don, thanks so much for the help!

Logger32 does not properly update the "frequency bar" above the Spectrum/Waterfall if the transceiver reports "Mark" frequency in AFSK or FSK. The "radio frequency" will be 'off' by the value of the MARK. This is a failing of Logger32 ... The K3/P3 does not change the MARK tone/cursor when switching between AFSK/AFSK R or between FSK/FSK R. There is some debate whether the "reverse" modes are meant to represent shift in the opposite direction from normal (in other words, shift *UP* in "reverse") or the "reverse" modes are the opposite sideband although amateur practice is to reverse the mark/space tones when shifting sidebands so the shift is correct in either sideband. 73, ...

The voltages Fred lists are correct for a float charger where you are charging at a rate of less than 0.05Cma for an indefinite period of time. The KXBC3 isn?t really designed to be used as a float charger, so it uses a somewhat higher rate of 0.1Cma (200ma) and is designed for 2000mah or larger cells. That 0.1Cma is an industry standard constant current rate, and it is meant to be used for a limited amount of time, about 16hr. is what the manufacturers recommend The datasheets available from most manufacturers don?t always list the voltages you can expect to see when using a 0.1Cma constant current charger, but Ansmann is the exception. Datasheets for both their 2100mah and 2500mah cells show a sharp voltage increase when reaching the fully charged condition increasing from about 1.35v at hour 10 (assuming you start with a discharged cell), up to about 1.45v at hour 11 where the voltage levels off. Their charge voltage curves continue nearly level (1.45v) from hour 11 out to hour 16. That flat curve represents a fully charged cell that cannot accept any more energy for chemical conversion. The 1.45v is 11.6v for 8 cells. As Fred mentioned, heat is the biggest enemy of any battery, so it would be best to stop charging once the voltage reaches about 11.5v, or even 0.3 or 0.4 volts sooner to avoid adding too much heat to the cells. Hopefully, my cells will last quite a while that way, but I will not hesitate to properly dispose of them and buy new ones if they give me any trouble. They can become very unreliable (read that as ?frustrating?) once they start to deteriorate. The KXBC3 should protect your cells in most cases, but it is probably best to avoid being too aggressive. Remember that it limits cell temperature to 40 deg. C which is their specification upper limit, but like most electronic components, they will last longer if the temperature is kept down a bit. Before retirement, I worked with several battery manufacturers on NiMH technology (and lithium technology as well), and their recommendations were quite similar to the above. Please heed Fred?s warning, these numbers do NOT have any relation to lead acid (SLA these days) batteries, or lithium cells for that matter!

Having a family get-together here, so haven't have a lot of time, but I sneaked away for a few minutes to see what mine read since I noted anomalies when I received my XG3 a couple of months ago. Here is what I found today with my KX3: Initially, with a -73dbm signal from my XG3, my KX3 read one segment (5db) over S9 (40m). Not too bad. Then I increased the XG3 output to -33 dbm, and the S-meter read 25db over S9. Returning the XG3 to -73 dbm gave an S-meter reading of S7 instead of the previous 5 over S9. I have seen this behavior in the past, but? I turned the radio and XG3 off for an hour and went back to it and checked the -73 dbm setting again and now I get S7 consistently. That surprised me, as I expected it to match the 5 over S9 I got the very first time I tried it. I cannot explain why I got 5db over S9 initially. I just tried the same thing on 80m and could not duplicate it there. No matter what I did there, I always got S9 with a -73dbm input. I will probably play with this some more when I get some time, but it is just a curiosity for me since I don?t use the s-meter all that often, and then only for relative readings to get a feel for what the band is doing, or for tuning signals. I don?t often care what the actual number is. Mark KE6BB So many variables between the transmitter and the S-meter, so little time.

Although probably not what you need, I stumbled across some cases in an unexpected place. RC enthusiasts have the need to carry around their transmitters too, so cases show up in their catalogs. These tend to be around 5 or 6 inches deep so probably a bit small for the K line but might be just the ticket for a KX3 plus accessories. They come in aluminum and plastic for as little as $28. I have not seen these personally but given that transmitters cost up to $3000 and get drug out in the field these cases might be sturdy enough. Just another idea.

They might as well just say "Steal me first". I always went for a crappy looking canvas camera bag and built what I needed inside to protect the gear. I feel the same way about radio cases. If it looks like it is protecting something expensive, it is probably worth stealing. Some of these cases are expensive enough to steal even empty!

The UTEC fans that came with my most recent KPA3 (September 2013) were very annoying to me since I have a quiet radio room with no amplifier. The problem was not so much one of volume as sound quality. The fan noise was buzzy, for lack of a better description, probably from a combination of undamped mounting and poor bearing design. For those who want to replace their fans with the Noctua NF-A6x25 I have a method to make the installation neater. Obtain two Molex two-terminal 0.1" connectors (WMLX-101 from Fry's Electronics or equivalent) before your new fans arrive. Follow Harry's instructions to use the Noctua silicon rubber anti-vibration mounts to attach the fans to the Elecraft fan panel and to attach the Elecraft fan screens with the Noctua-supplied screws. Some care is required when pulling the mounts through the fan mounting holes so you don't bend the aluminum fan panel at the thin points. Measure the two different lead lengths on the old fans and cut the respective new fan leads to the same lengths plus a little extra to crimp the new Molex connectors on. Cut the black sleeve back to expose enough wire length to crimp on the Molex terminals and attach the housing. Strip the red and black wires on each lead and crimp and solder on the new connector terminals. Remember the red fan leads go to the left when viewed from the rear of the K3. Planning the orientation of the wires is important for the neatest end result. Fold the yellow wire back into the sleeve and snap the terminals into the connector block in the correct orientation on each lead (so that the red wire is on the left when installed). Plug the two connector blocks onto the KPA3 fan pins and attach the fan panel per the original KPA3 instructions. You will now have minimal interference from the fan leads in the space between the panel and KPA3 heat sink. Using this technique is most important when you have coaxial cables from other accessories occupying the same area, as I do. Enjoy the quiet fans - I am! 73 Gary, N7IR John Farmer wrote: > I'll do the same. Trimming the contact plug down will be > simpler than cutting it off and wiring on a 2 pin.

Another trick for cutting open cell foam, especially when trying to cut a non-linear profile, is to wet it, freeze it and cut it while frozen with a knife blade, or a finer toothed straight set blade, in a jig saw. 73 de Dennis KD7CAC Scottsdale, AZ On Aug 25, 2014, at 4:57 PM, Phil Wheeler wrote: > Very nice.

Editor? I am having some trouble getting the K3 Frequency Memory Editor to write, and read, from the KX3. I installed a 2m module and so far that all seems to be working fine (have the latest firmware) and now I am looking to program the memories via the computer. The utility connects to the rig on port 3 and 9600bps but the smaller window that comes up when sending or receiving from the KX3 locks up when writing, or reading, channel 00. Any ideas?

This of course means that when the "last bug" is fixed that firmware will self-morph under cover of darkness to produce another bug to fill the vacated space. If you have been keeping careful records on these issues you will recognize the pattern. For some the trick is to ship when the new bug has some semblance of a feature, a process mastered by Microsoft in the 20th century. This led to the interesting procedure of using "maintenance" (a snooty word for "fixit") software to introduce new features, still widely practiced in the industry to this day. Firmware self-morph can sometimes be defeated by running high wattage grow lights 24/7 in program development areas. The usual resulting increase in developer insomnia is handled by company-issued sunglasses not to be taken out of the development area. 73, Guy On Mon, Aug 25, 2014 at 9:09 PM, Wayne Burdick wrote: > Hi John, > > We're just now cleaning up "the last bug," which was a bit challenging. > Trust me, we're just as anxious to ship as everyone else is to receive. > > The manual was blessed today and should be posted soon. > > Wayne > > On Aug 25, 2014, at 6:05 PM, John_N1JM wrote: > > > Anyone received notice of shipment outside of Field Testers? > > > > John N1JM > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 k2av.guy at gmail.com > From zendoc at netspace.net.au Tue Aug 26 04:47:24 2014 From: zendoc at netspace.net.au (Dr John H Farmer) Date: Tue, 26 Aug 2014 18:47:24 +1000 Subject: [Elecraft] [K3] Fan Replacement Message-ID: Hi Gary, I had thought about re-wiring the fans with 2 pin Molex connectors ( I have a packet of them here) but took Harry's lead and trimmed down the 3 pin instead. It was easy and the result very neat - the plastic is soft and easily cut with a hobby knife. I cable tied the excess lead lengths and tucked them out of the way behind the fans. I was worried about whether the excess would get in the way of other things inside the cabinet, but so far so good. I do think your way is tidier though. May re wire my fans soon...

I've used the Amateur Contest Log software, by N3FJP, for several years. I can't honestly say it is "the best", but it certainly is very good software--and very well enhanced! Since Scott, N3FJP, started devoting nearly full time to his software (it was something of a sideline previously, but still good stuff!), he has made numerous enhancements to both his logging software, and to his various contest logging programs as well. It all just keeps getting better, and with lots of extra conveniences. The software isn't free, but it certainly isn't very expensive either. There is a relatively modest additional fee to get his entire package, which includes a plethora of contest specific logging programs, and it is all a lifetime deal. For you contesters and DX hounds, Scott has incorporated a very "seamless" process for interfacing with LOTW--something that could drive you nuts otherwise!!! Once you have linked the logging software to LOTW, which isn't all that difficult, all it takes is a couple of keystrokes to update and/or download LOTW stuff. But this is just an example. Here, for example, is what I just received as to info on the latest update: Amateur Contact Log 4.8 includes the following enhancements: - Ability to set DX spots filtering. - Ability to display a DX spots band map (press Ctrl E from the main form to display). - Printing of multiple QSL strips on one label. Note that many of the other enhancements listed in the contesting software below were already added in AC Log 4.7 and Field Day Contest Log 4.3. Amateur Contact log 4.8 has actually already been on the website a little over a week. This is the first opportunity I've had to send out the announcement because of other scheduling commitments. Anyway, I'm not "hawking" this software so much as I am reporting that it works, and works well. I do know a lot of folks who have gone to this software recently, and they all seem to be pleased with it. The main thing, perhaps, is that the creator of the software is pretty much devoting full time to the software's development, and that should be a big plus. Also, they are very receptive to suggestions for enhancements. If you want to take a look, go to www.n3fjp.com.

In-Reply-To: References: Message-ID: <325063577.6847735.1409082171524.JavaMail.root@comcast.net> Hello Elecrafters, I was having problem with my laptop computer shutting down while playing video clips. First the LCD display would go black, then the audio would stop, then the puter would shut off. After waiting a bit, I could restart and would get a message saying this was happening due to "thermal overload"..... air vents on bottom of laptop being blocked when actually on my lap. Found this "lap chill mat" in local BJ's and it solved the problem. Check this link : http://targus.com/US/lap-chill-mat-awe55us It has two fans, plugs in to usb port, very quiet, can't hear them at all.....haven't yet checked for RFI. I haven't been closely following the "air flow" issue, but I thought maybe this "lap chill mat" might work with radio gear as well as laptops. The link to the Targus web site shows the price as $39.99......but a google search finds them much cheaper at various vendors.....$ 17.09 at Walmart. Hope this helps someone.

Several other users complained about the same thing, and hardly any serious contester has used his stuff for years. There are still more powerful logging programs (for both DXing and contesting) out there that are free and well supported as well, but N3FJP's software always had a nice feel to it so hopefully things have indeed changed for those who may be looking for a middle ground. 73, Dave AB7E On 8/26/2014 4:49 AM, w7aqk at cox.net wrote: > Good Morning All, > > Every so often someone asks about good logging software.

I took some time to really dig in an concluded that I didn?t have the right tools to do even basic experimentation. I applaud that you?ve made it public and I?d encourage Elecraft to continue in this spirit where it isn?t commercially to your disadvantage. I would also encourage using something like github as a great way to share the code that permits maximum utility for people trying to work with the code. This form of version control is radically different (and in most ways superior) to everything that has come before it. [ IF you aren?t using it in-house - it might be worth investigating if it is time to migrate from whatever you are using, to git.] I?ve helped a few major software development organisations move to git and the end results can be quite excellent. I certainly wouldn?t consider any other form of code control these days. ] Wayne ; Best wishes and I?m always willing to chat about this technology and how to use it within organisations.

My only complaint was the color of the fans, I would have like them in black. My shack is very quiet and I even have very quiet fans in my PC. (The loudest thing in the shack is the air vent from the Central air) I'm glad others have found this to be a worthwhile mod. ? ________________________________ From: Gary Hembree To: Elecraft List Server Sent: Monday, August 25, 2014 6:58 PM Subject: Re: [Elecraft] [K3] Fan Replacement Thanks to Harry and John for the excellent advice on the replacement fan. The UTEC fans that came with my most recent KPA3 (September 2013) were very annoying to me since I have a quiet radio room with no amplifier.? The problem was not so much one of volume as sound quality.? The fan noise was buzzy, for lack of a better description, probably from a combination of undamped mounting and poor bearing design. For those who want to replace their fans with the Noctua NF-A6x25 I have a method to make the installation neater.? Obtain two Molex two-terminal 0.1" connectors (WMLX-101 from Fry's Electronics or equivalent) before your new fans arrive.? Follow Harry's instructions to use the Noctua silicon rubber anti-vibration mounts to attach the fans to the Elecraft fan panel and to attach the Elecraft fan screens with the Noctua-supplied screws.? Some care is required when pulling the mounts through the fan mounting holes so you don't bend the aluminum fan panel at the thin points. Measure the two different lead lengths on the old fans and cut the respective new fan leads to the same lengths plus a little extra to crimp the new Molex connectors on.? Cut the black sleeve back to expose enough wire length to crimp on the Molex terminals and attach the housing.? Strip the red and black wires on each lead and crimp and solder on the new connector terminals.? Remember the red fan leads go to the left when viewed from the rear of the K3.? Planning the orientation of the wires is important for the neatest end result.? Fold the yellow wire back into the sleeve and snap the terminals into the connector block in the correct orientation on each lead (so that the red wire is on the left when installed).? Plug the two connector blocks onto the KPA3 fan pins and attach the fan panel per the original KPA3 instructions. You will now have minimal interference from the fan leads in the space between the panel and KPA3 heat sink.? Using this technique is most important when you have coaxial cables from other accessories occupying the same area, as I do. Enjoy the quiet fans - I am! 73 Gary, N7IR John Farmer wrote: > I'll do the same.? Trimming the contact plug down will be > simpler than cutting it off and wiring on a 2 pin.

Also, I think previously Scott was more restricted on how much time he could devote to revisions. However, now that he is more or less doing this full time, I think he spends a lot more time evaluating suggestions when making changes. After all, it is user feedback that reveals a lot of shortcomings not anticipated previously. In any event, I have seen him reply positively to various queries about features, or the lack thereof. I rather doubt that all the enhancements he has provided so far had their Genesis only from just Scott's own contemplation. Also, this is not a "one size fits all" software. I'm sure some folks will find it lacking in some way with respect to their hot buttons. I, for one, have little comprehension of the complexities of making various changes. For all I know some requests may necessitate substantial revision, which may well not be practical. You just have to see if it fits.

Several different sizes of Optimus & Radio Shack branded speakers were produced over the years that all sound great. Specifically the two sized metal cased units I have are 6? X 4 X 4 and 7 X 4? X 4?. These both at two way speakers having a small tweeter. The older wooden cased one doesn't have a tweeter but is similar in size. I'm not sure if they're still in production though. 73, Charlie k3ICH ----- Original Message ----- From: "Gerry leary" To: "Charlie T, K3ICH" Cc: Sent: Wednesday, August 27, 2014 8:12 AM Subject: Re: [Elecraft] [K3] A speaker for the K3 Are you talking about the speakers that are about 4 inches wide about 7 inches long and about 45 inches deep and I have the screw on bracket?

I've used one for years as a utility monitor and would really like to find a half dozen of them for use with various rigs including both K3s. I've been using "bookshelf" speakers as suggested by Wayne many years ago - mine are Sony B1000 (10 1/4" x 6 3/4" x 7 1/4") - $68/pair on Amazon. Similar speakers are available from many places at similar prices - for example, Best Buy (Insignia 5 1/4" 2-Way Bookshelf Speakers" - $60/pair). I've recently found 3" bookshelf speakers (3.6" H x 3.6" W x x 4.6" D) rated for 90 Hz - 18 KHz for $19/pair on Amazon that I'm preparing to test an alternative to the old XTS-25. See: Amazon also show a pair of 4" bookshelf speakers (4.8" x 4.8" x 5.2") for $28/pair that looks like a good match to the K3 (and a whole lot less less than $300/pair ). 73, ...

See release notes below, which cover all significant changes since the current production release (2.12). If you're interested in testing this release right away, please email me directly and I'll send you a copy. We'd like to go to beta with this release soon. 73, Wayne N6KR * * * MCU 2.18 / DSP 1.30, 8-21-2014 New Features: * 2-M DIRECT FREQUENCY ENTRY FROM OTHER BANDS: Range is 120-168 MHz. Note: Sensitivity falls off as you move out of the 144-148 MHz range. * 2-M TRANSMIT LIMITS: Normally, 2-meter transmit is limited to 144-148 MHz. This can be increased to 141-151 MHz for MARS use. The range can also be limited to 144-146 MHz for KX3 owners outside the U.S. (see separate instruction sheet). * 2M/4M ANT. JACK PROVIDES OPTIONAL +5VDC DURING TRANSMIT: Many high-band transverters and other gear can use a DC voltage of 3-12 V on the center conductor of the antenna coax to provide T/R switching or other functions. The KX3-2M/-4M module can now place +5VDC (+/- 0.3 V) on the antenna jack if desired. To turn this feature on/off, locate the 2M/4M menu entry and tap ?2? (ATTN switch). The parameter will be either TXant 5V- (off) or TXant 5V+ (on). ?ant? is displayed as a small antenna symbol. * KX3-2M ADAPTER SUPPORT (non-ATU): The KX3-2M-ADAPT module provides the physical and electrical interface to the KX3 when there is no ATU installed. If the adapter is installed, make sure the ATU MD menu entry is set to NOT INST. Bug fixes: * CW TIMING BUG FROM REV 1.95 CORRECTED: Element lengths with the internal keyer were slightly too short due to a calculation error. * PL TONE FM DEVIATION ERROR: The PL tone deviation displayed in the menu was about 40% lower than the actual deviation value in effect. Because of this, repeater users should re-check their PL deviation setting. To do this, locate the FM DEV menu entry, then tap ?1? to switch to PL DEV. Set the value to 0.35 (kHz)?the new default?unless some other value is applicable. * CW-IN-SSB IMPROVEMENT: The operator?s specified CW QSK delay is now used during CW-in-SSB, even with external CW keying. (This was already working with the internal keyer.) * KXPA100 AUTO POWER-ON WITH PX3: If a PX3 and KXPA100 are both in the system, KXPA100 automatic power-on will now work even if the PX3 is turned on first. (Note that at present there is no way to do automatic power-on of the PX3 itself.) * INCREASE IN ALLOWED TX CURRENT: Allows full-power output on some bands where previously a drop to 5 watts had been observed (with an external 12-14 V supply). * KX3-2M BAND-CHANGE FIX: With SLEEP enabled, a band change from 2 meters to any other band was causing the 2-m module to be left powered up.

It does say that the K3 will transmit RF. I presume the intent is to allow you to tune a manual antenna tuner. If you need to tune a linear amp, I guess that behavior would be cumbersome, but you can always reduce the power and do a keydown to tune the amp. I don't use TUNE myself. 73, Don W3FPR On 8/27/2014 3:42 PM, Andrew Lenton (Home) wrote: > I have noticed that when I hit tune the K3 goes to TX, however, it does not > key the linear, key line, so the linear stays in standby how do I get around > this > From dave at nk7z.net Wed Aug 27 17:12:26 2014 From: dave at nk7z.net (David Cole) Date: Wed, 27 Aug 2014 14:12:26 -0700 Subject: [Elecraft] www.kl7uw.com - Hacked In-Reply-To: <53FE4099.9070706@triconet.org> References: <201408271618.s7RGI87P065361@huffman.acsalaska.net> <1409158396.7085.190.camel@nostromo.NK7Z> <53FE4099.9070706@triconet.org> Message-ID: <1409173946.7163.9.camel@nostromo.NK7Z> I understood it completely...

Andrew, The manual does not say anything about activating KEYOUT for a TUNE. It does say that the K3 will transmit RF. I presume the intent is to allow you to tune a manual antenna tuner. If you need to tune a linear amp, I guess that behavior would be cumbersome, but you can always reduce the power and do a keydown to tune the amp. I don't use TUNE myself. 73, Don W3FPR On 8/27/2014 3:42 PM, Andrew Lenton (Home) wrote: > I have noticed that when I hit tune the K3 goes to TX, however, it does not > key the linear, key line, so the linear stays in standby how do I get around > this > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 mteberle at mchsi.com From kd7gc at q.com Thu Aug 28 00:22:00 2014 From: kd7gc at q.com (kd7gc) Date: Wed, 27 Aug 2014 21:22:00 -0700 (PDT) Subject: [Elecraft] Tuning your radio and amplifier to your amtenna In-Reply-To: <00b001cfc265$b1e4a1b0$15ade510$@STL-OnLine.Net> References: <00b001cfc265$b1e4a1b0$15ade510$@STL-OnLine.Net> Message-ID: <000001cfc277$8eaa3590$abfea0b0$@com> Hello Jim, In major part I agree with your suggested method for tuning up and amp, but I would never begin my tuning with an output from my transceiver of 4 watts. I have never heard of anyone suggesting that tuning should begin with anything close to 4 watts. I generally go thru 3 or 4 steps, but I start with my transceiver set to about 25 or 30 watts output. I bring my drive up in say 3 or 4 increments until I reach my desired amp output, usually in the range of about 60 or 70 watts of drive, at least for smaller amps. However, when I tune up my Henry 5K I don't exceed about 45 watts of drive because I would already be over 1500 watts out. At 70 watts of drive I would be running over 3KW, or 3.5 KW on 40 or 75 meters. HTH Alan R.

I have tune settings for each amp for each band on a yellow sticky next to the amp, so I set those, then hit it with about 25W, tweak, run drive to see close to 1500, and retune for maximum smoke as indicated by the SWR/power meter. I tune with dits, so the duty cycle is 50%, less stress than full power carrier, but gives me correct tuning for full power. On the other hand, if you're tuning an auto tuner like the KAT500, you want to tune it with drive power only, the amp off. 73, Jim K9YC From jim at audiosystemsgroup.com Thu Aug 28 02:02:57 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 27 Aug 2014 23:02:57 -0700 Subject: [Elecraft] [K3] A speaker for the K3 In-Reply-To: <2159751FF3AD4A48B42F3B6F12368537@pinnacle05df05> References: <53FCDAAC.9000505@phonemaspeakers.com> <000f01cfc18a$78fe8ef0$6afbacd0$@verizon.net><53FD243A.7050608@subich.com> <004e01cfc1dd$3df4f2b0$b9ded810$@com> <2159751FF3AD4A48B42F3B6F12368537@pinnacle05df05> Message-ID: <53FEC611.9040907@audiosystemsgroup.com> On Wed,8/27/2014 4:53 AM, Charlie T, K3ICH wrote: > little metal cased, Radio Shack "Optimus" I agree with the recommendation.

You can certainly loose the base frequencies in a voice without impacting understandability. Raising the distortion on the other hand will have bad effects almost immediately, and they will get worse as the distortion rises. One of the reasons I've been able to get through the W1AW/n pileups is the low distortion of the K3 and KX3, and the use of your (K9YC's) non-flat response recommendations to get maximum intelligibility for my 100 watts. 73 Bill AE6JV ------------------------------------------------------------------------- Bill Frantz | When it comes to the world | Periwinkle (408)356-8506 | around us, is there any choice | 16345 Englewood Ave www.pwpconsult.com | but to explore? - Lisa Randall | Los Gatos, CA 95032 From elecraft at mailman.qth.net Thu Aug 28 02:32:47 2014 From: elecraft at mailman.qth.net (Harry Yingst via Elecraft) Date: Wed, 27 Aug 2014 23:32:47 -0700 Subject: [Elecraft] [K3] A speaker for the K3 In-Reply-To: <53FEC611.9040907@audiosystemsgroup.com> References: <53FCDAAC.9000505@phonemaspeakers.com> <000f01cfc18a$78fe8ef0$6afbacd0$@verizon.net><53FD243A.7050608@subich.com> <004e01cfc1dd$3df4f2b0$b9ded810$@com> <2159751FF3AD4A48B42F3B6F12368537@pinnacle05df05> <53FEC611.9040907@audiosystemsgroup.com> Message-ID: <1409207567.23064.YahooMailNeo@web125904.mail.ne1.yahoo.com> RCA also made one that is pretty much the same thing (I bought mine at radio shack about 10 years ago) ________________________________ From: Jim Brown To: elecraft at mailman.qth.net Sent: Thursday, August 28, 2014 2:02 AM Subject: Re: [Elecraft] [K3] A speaker for the K3 On Wed,8/27/2014 4:53 AM, Charlie T, K3ICH wrote: > little metal cased, Radio Shack "Optimus" I agree with the recommendation.

Note that I said flat response in the voice range. That's 200 - 4,000 Hz. Cheap speakers have bumpy response in the midrange, which produces phase distortion, which reduces speech intelligibility. My recommended low cut on TX gets rid of stuff in the <400 Hz range before it wastes TX power. I generally recommend response flat down to 100 Hz on the RX end, except with KX3, whose speaker output stage is current limited, to about 300 Hz to increase headroom (that means it can be louder in your headphones or speaker before it gets distorted). 73, Jim K9YC From nf4l at nf4l.com Thu Aug 28 05:27:18 2014 From: nf4l at nf4l.com (Mike Reublin) Date: Thu, 28 Aug 2014 05:27:18 -0400 Subject: [Elecraft] K3 Tune button, does not key a linear In-Reply-To: References: Message-ID: CONFIG:TUN PWR to set the level. 73, Mike NF4L > The manual does not say anything about activating KEYOUT for a TUNE.

Yes, you can do this if your amp is close by ? and you remember to do it when necessary. I use a couple of different amps and autotuners: The KPA500/KAT500 and an ALS-600/MFJ-998. I leave all autotuners in MANUAL mode and memorize settings. When I change bands, I like to press TUNE to check SWR before operating even though the memories have been set ? just in case something has changed ? and it would be nice if I just put out a 20W carrier (I leave my K3 TUNE set to 20 watts as suggested for best KAT500 tuning). So when I press TUNE, I get almost full power out of the KPA500, and 200-300 watts out of the ALS-600. The KAT500 follows band changes via the accessory cable so if nothing has changed in the antenna system, there is no amp fault. With the ALS-600/MFJ998, the MFJ-998 requires some RF before it can determine the band. Often you have a momentary high SWR that trips out the amp when changing bands. Not that big a deal. But for my set-ups, I wish the K3 amp-enable output was programmable so it could be set OFF on TUNE. But I understand this is hard-wired and so can?t be done. Phil ?

First off, putting a carrier on the air to tune/test/analyze a antenna is probably not the correct thing to do.? The reason is simple, if it is a new antenna you have no idea what the R and X numbers are for where the j0 point is, correct?? Then with all of the antenna analyzers out there, take a look at the antenna wideband........? That's right, wideband.? Why spend endless amounts of time trying to "Tune Match" the antenna and cause unnecessary signals on the air if you don't have to?????? Second, use the modern tools available.? And not just a ATU.? The whole idea of putting up a antenna is to understand what it is and how best to put RF power into it.? Sure the ATU can match an antenna that is a MegaHertz high in frequency and at your target frequency it is 200 ohms.? Why not use a 4:1 balun and make the ATU not absorb the loss of matching????? OK, My method is not new, but I think it serves repeating.?? New amplifier.? Not automatic, one that requires band and tuning settings.? DO it into a dummy load, write down the numbers.? Take the analyzer and find out where the antenna is resonant.? Yes, it will be more efficient if it is resonant where you want to operate. Of course if it is a weird configuration, then at least write down the R and X numbers for the frequencies of interest.? Then take the steps necessary to limit the loss in the system.? Baluns if necessary, tuners of your choice.? But use the analyzer to "tune and match" the antenna, record the numbers. Then hook up the radio, amplifier, tuner, etc and if necessary fine tune the final settings and record them for future use. Next time you decide to switch bands just use the presets you recorded.? Less interference on the bands, and less stress for the equipment.? OK, There is my 2 cents worth, like someone else said, back into my hole.?

If I understand the original post, this discussion is not about a new antenna, it's about tuning an amplifier when changing bands. It's something I would do several times during a contest, and before doing it, I listen to find a clear frequency. If I can't get the amp tuned in 10 seconds or so starting from settings I've written down, something's wrong. 73, Jim K9YC From w2blc at nycap.rr.com Thu Aug 28 15:20:30 2014 From: w2blc at nycap.rr.com (W2BLC) Date: Thu, 28 Aug 2014 15:20:30 -0400 Subject: [Elecraft] [K3] A speaker for the K3 In-Reply-To: <53FF4855.4050606@socal.rr.com> References: <53FF4855.4050606@socal.rr.com> Message-ID: <53FF80FE.4030903@nycap.rr.com> Not worried about the size of speakers, I use a pair of Behringer MS40 amplified speakers. They are two channel input (left and right each) with an on-board amplifier. There appears to be no sensitivity to RF. You can plug earphones directly into the speakers - and there are controls for bass/treble and separate volume (gain) for each input. Size wise, they are a little large for portable operation, but just fine for the home station. I used to think they were over-kill, but after seeing the projected delivered cost of a single non-powered speaker given in another post - I have decided the Behringers are quite cost effective at $150 from Amazon.com (may be less at other outlets). I run the K3 into one input and my computer into the other input.

See release notes below. You'll need revision 1.13.8.24 or later of our KX3 Utility program to download and install firmware. For full instructions on loading beta releases, refer to our KX3 software page: http://www.elecraft.com/KX3/KX3_software.htm 73, Wayne N6KR * * * MCU 2.18 / DSP 1.30, 8-21-2014 New Features: * 2-M DIRECT FREQUENCY ENTRY FROM OTHER BANDS: Range is 120-168 MHz. Note: Sensitivity falls off as you move out of the 144-148 MHz range. * 2-M TRANSMIT LIMITS: Normally, 2-meter transmit is limited to 144-148 MHz. This can be increased to 141-151 MHz for MARS use. The range can also be limited to 144-146 MHz for KX3 owners outside the U.S. (see separate instruction sheet). * 2M/4M ANT. JACK PROVIDES OPTIONAL +5VDC DURING TRANSMIT: Many high-band transverters and other gear can use a DC voltage of 3-12 V on the center conductor of the antenna coax to provide T/R switching or other functions. The KX3-2M/-4M module can now place +5VDC (+/- 0.3 V) on the antenna jack if desired. To turn this feature on/off, locate the 2M/4M menu entry and tap ?2? (ATTN switch). The parameter will be either TXant 5V- (off) or TXant 5V+ (on). ?ant? is displayed as a small antenna symbol. * KX3-2M ADAPTER SUPPORT (non-ATU): The KX3-2M-ADAPT module provides the physical and electrical interface to the KX3 when there is no ATU installed. If the adapter is installed, make sure the ATU MD menu entry is set to NOT INST. Bug fixes: * CW TIMING BUG FROM REV 1.95 CORRECTED: Element lengths with the internal keyer were slightly too short due to a calculation error. * PL TONE FM DEVIATION ERROR: The PL tone deviation displayed in the menu was about 40% lower than the actual deviation value in effect. Because of this, repeater users should re-check their PL deviation setting. To do this, locate the FM DEV menu entry, then tap ?1? to switch to PL DEV. Set the value to 0.35 (kHz)?the new default?unless some other value is applicable. * CW-IN-SSB IMPROVEMENT: The operator?s specified CW QSK delay is now used during CW-in-SSB, even with external CW keying. (This was already working with the internal keyer.) * KXPA100 AUTO POWER-ON WITH PX3: If a PX3 and KXPA100 are both in the system, KXPA100 automatic power-on will now work even if the PX3 is turned on first.

I will leave it to others to judge whether they achieved that goal, but somebody must like them because they're still in production over 50 years later. I have one but not being a "bug" guy I've found I prefer a more conventional single-lever like the Kent SP-1 or the AME Bushwhacker. Again, no actual bug experience here, but the old Nye Viking SSK-1-K has a "manual" mode which sets the left paddle to key for however long it is pressed while the right paddle will still send dits at the keyer's set speed. If they can accomplish that it with '70s era CMOS technology it would seem like it would be "do-able" in today's technology. But, there may be some subtle points that I'm missing here, I've been known to achieve that before HI HI!!

Pg 51, the very last step, is the install of C167 (.001 uF, "102"). Appendix A shows a "more or less" photo of this capacitor. I can't locate this capacitor, but then, I may have it and it may not look like the one in the photo. There are some smaller capacitors remaining that are yellow (as opposed to red in the photo) marked "102" on one side, and "K1J" on the other side. The other oddity is that they don't look "monolithic" as described in the appendix (they are small), nor do they match the outline on the board (but then, the step does say to bend the leads). But this one would require an extreme amount of bending because the holes are quite far apart in C167. Or should it be about the same size as the 103's and 104's?

Yes, you will have to bend the leads straight out and then form them again at a right angle to fit the hole spacing.

Message-ID: <54024FA1.5020802@rogers.com> Hi folks, I'm working on my XV432 kit this weekend. I ordered the high accuracy crystal and the crystal oven options as well. I'm on page 31 of the XV432 manual, where it is asking me to locate L4 and L19 for installation. I see that L19 appears to get replaced when installing the high accuracy crystal option. The manual says: L4 has an orange body with four turns. (It looks red to me and it has 3.5 turns, close enough I guess) L19 has a yellow body with four turns. (I count 4.5 turns, _definitely_ one more turn than L4. At least it's yellow) The installation instructions that come with the high accuracy crystal option say to remove L19 from the circuit board. Since I'm just about to install it this seems like a good time to make the substitution. EXCEPT, it says that L19 has a RED plastic coil form, not yellow like the XV432 manual says. I do note that the substitute coil that comes in the high accuracy crystal option is yellow and has exactly the same 4.5 turns as the yellow bodied coil called L19 in the XV432 assembly manual. I assume the error is in the instruction sheet for the high accuracy crystal option, and that they meant to say that L19 is yellow and not red. However, I'd feel safer if someone who has built one before could kindly confirm this. The second thing that bothers me is why does one 4-turn inductor have one more turn than the other 4-turn inductor? Any assistance will be gratefully accepted.

Look at the markings on the crystal that came with the XV432, and compare it with the crystal shipped with the High Accuracy Kit - if it is the same, you can put either crystal in and Check L19 as well, they should be the same. In other words, the High Accuracy Kit is a retrofit for older XV432 transverters, and is not necessary for new ones. 73, Don W3FPR On 8/30/2014 6:26 PM, Ken Alexander wrote: > Hi folks, > > I'm working on my XV432 kit this weekend.

Not much overall but the forest smells much better. There is a spicy scent in the air, I imagine it is from all the cedar in the ground. After a warm to hot week these cooler days feel nice but presage autumn. So I will be out cutting firewood soon which takes its toll on my hands. You will all notice I am sure. The sun has been more active all week as have the summer storms. The mixture of the two modify signals with QRN and QSB. Working into Alaska has been interesting. Depending on the day and time the auroral oval is right overhead for that state. Reciprocal signals go out the window under these conditions. One day the noise is extreme to me while on the next day it is on the other end. The quiet of the forest is soothing after those contacts.

The internal one (K144XV) has one drawback: no adequate cooling! Cooling is done only passively using the left side of the enclosure. As JT65 on EME is a key-down mode you will see that power drops soon and dramatically, i.e. starting with 10 watts it will drop down to 5-6 watts after 2-3 overs already due to missing heat dissipation. So you will want to do some external cooling to lessen that effect (but you will not completely get rid of it from my experience). Besides this the K144XV is very sensitive, whenever I use mine I switch off the external pre-amp which is needed for all other transceivers overhere. :-) And don't forget to order the K144RFLK to keep the frequency stable. What you should also consider is which amplifier you want to use. So the XV144 might be the better solution if you need more drive power. If you want to think outside the box you can also check other manufacturers. For serious contesting and EME I'm using the HA1YA transverter ME2HT-PRO with +30 dBm mixer (http://www.ha1ya.hu/htmkepek/me2t_protransverterspec.htm) and 60 watts (including adequate cooling) to drive a GS35 amp.

The orders have finally slowed down a bit and since finally obtaining a decent bench-top "mill/drill" I've been able to get a few ahead and now have some of the Vibroplex "round pendulum" versions in stock for immediate shipment. I also have prepared "blanks" in stock for the McElroy and Metric round pendulum types that use a larger diameter rod so all that's necessary is for the proper sized hole to be drilled and chamfered to send these as well. The "flat pendulum" types still have to be made as ordered because I'm still waiting on the right sized cutting bit (back ordered) to allow me to cut the slot on the mill. Right now I have to rough it out on the jigsaw and file to size. Thanks again to all those that have ordered and are now using them. Any inquiries should be direct email to me rather than on the reflector to keep the off topic clutter to a minimum.

It adds a characteristic ?hollow? sound to all signals. NR turns noise reduction on. It doesn?t apply to DATA or FM modes, or with AGC turned off. Hold ADJ to display the NR setting, which is saved per-mode. Use the VFO B knob to tailor NR for the present band conditions. In general, the higher the number, the more aggressive the noise reduction. Settings F1-1 through F4-4 are recommended. F5-1 through F8-4 use a different algorithm, where the -x part of the setting indicates the degree of mix between the DSP-processed and unprocessed signals (-1 is about 50% processed, -4 is 100%). A small M appears to remind you that a Mixed setting is in effect, e.g. NRM F5-1. also from: http://www.elecraft.com/K3/K3FAQ.htm How does the Noise Reduction work? NR depends on correlation of the present input with previous input. The system does not actually provide Noise Reduction; it provides Signal Selection. In other words, its default is to pass nothing at all. It has to believe there is a signal present, and then it builds a filter, or set of filters, around the spectral components of the signal it thinks is there. Random noise has no correlation, voice has moderate but not perfect (unless you whistle a pure tone) and CW has excellent correlation. As a result, noise is heavily suppressed (no filter is built to pass it), voice is partially suppressed (hence it needs some additional gain to compensate for this effect so the same AF level will produce about the same audio level with a moderate S/N speech signal) and CW is hardly suppressed at all (hence it does not need any gain boost). NR is not recommended in Data Mode. Data is already getting a matched filter in the demodulator. You might lose a few symbols as the NR settles around the signal, and it might suppress a very weak signal that you could otherwise copy. NR in the end is intended for modes you listen to. lastly I saved this gem of a post from Jack WA9FVP ==== Re: [Elecraft] [K3]Noise Filter (NF) ADJ wa9fvp Thu, 27 Dec 2012 16:19:36 -0800 There's no documentation but as far as I can tell-- F1-x through F4-x defines the amount of noise reduction or how aggressive the filter attacks the I.F. noise. F5-X through F8-X defines the amount of reduction and the level that's mixed with the filtered and non-filtered I.F. Note that "m" which means "mix" will appear after F5-X and above. X defines the delay. Delay is the amount of time it takes for the filter to converge on a non-sinusoidal signal or the noise. The higher the number, the longer it takes for the noise to reduce to a low level. I hope this helps. Jack WA9FVP F1-x through F4-x are for CW F5-x through F8-x are for SSB ==== -- GB & 73 K5OAI Sam Morgan From k5oai.sam at gmail.com Sun Aug 31 17:48:38 2014 From: k5oai.sam at gmail.com (Sam Morgan) Date: Sun, 31 Aug 2014 16:48:38 -0500 Subject: [Elecraft] K3 FAQ webpage broken?

I've not done EME (too many tall trees in the way), but I do own an XV144, and recently set it up with a vintage Mirage 2W in to 150W out brick amp of pre-MFJ vintage. Some thoughts based on my experience. The internal transverter is rated for about 10W, the external unit for 20W. Both should be carefully cooled and derated for keydown modes, which is one reasonI sought out that particular Mirage. The other reason is that minimizing temperature rise in either transverter improves frequency stability. To minimize heat in the XV144, it should be driven from the K3 so that 1 mW generates full rated power. Running the transverter at reduced output also helps. Since I need only 2W drive, I've set up my XV144 so that 1 mW in yields 10 W out. For whatever reason, both my XV144, as well as my XV220 that has been on long term loan to neighbor K6EU, both have some degree of instability, to the extent that both behave differently with top cover on and off. One thing I suspect as a cause is poor EMC practice. The antenna connector is bonded to the chassis, but BNC connectors for interface to the transceiver are insulated from the chassis. My XVs are fairly old -- I bought them used in 2005 already built, so perhaps current production is better in this regard. And the XV144 did get a glowing review in QST. 73, Jim K9YC On Sun,8/31/2014 8:25 AM, Oliver Dr?se wrote: > Hi Rich, > > don't know the external one (XV144) myself so cannot comment.

They are good at power and frequency stability. Do some search in this elecraft email listing, you will find some discussion in the past about XV144. 73 Johnny VR2XMC ________________________________ ???? Oliver Dr?se ???? elecraft at mailman.qth.net ????? 2014?08?31? (??) 11:25 PM ??? Re: [Elecraft] EME Radio - 144mhz Transverter or 2m Module Hi Rich, don't know the external one (XV144) myself so cannot comment. The internal one (K144XV) has one drawback: no adequate cooling! Cooling is done only passively using the left side of the enclosure. As JT65 on EME is a key-down mode you will see that power drops soon and dramatically, i.e. starting with 10 watts it will drop down to 5-6 watts after 2-3 overs already due to missing heat dissipation. So you will want to do some external cooling to lessen that effect (but you will not completely get rid of it from my experience). Besides this the K144XV is very sensitive, whenever I use mine I switch off the external pre-amp which is needed for all other transceivers overhere. :-) And don't forget to order the K144RFLK to keep the frequency stable. What you should also consider is which amplifier you want to use. So the XV144 might be the better solution if you need more drive power. If you want to think outside the box you can also check other manufacturers. For serious contesting and EME I'm using the HA1YA transverter ME2HT-PRO with +30 dBm mixer (http://www.ha1ya.hu/htmkepek/me2t_protransverterspec.htm) and 60 watts (including adequate cooling) to drive a GS35 amp. HTH - hope that helps! 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 30.08.2014 14:26, schrieb Richard Thorne: > I'm starting to get the bug to try something different and EME has > grabbed my attention. > > I already have a couple K3's and would like to put one to use for > EME.

I'd like to provide a couple of technical details, and to give credit where it is due. To achieve the excellent results shown in your paper for the K3, we used a combination of four techniques: 1. A hybrid PLL/DDS synthesizer with a very high C/L ratio VCO: Many of the radios shown in your plots use unfiltered DDS for their VFO, or in the case of PLL designs, VCOs with a much higher C/L ratio than the K3. Both of these design decisions can increase phase noise and dynamic artifacts. To preserve a consistently high C/L ratio, we use up to 128 different C/L combinations as the VCO is band-switched. (This is in contrast to the usual 1, 2, or 3 VCO C/L ranges used in other rigs.) We also used very narrow-band crystal filtering of the DDS output to completely remove any of the usual spurs due to quantization, etc. John Grebenkemper assisted greatly with the synthesizer design. 2. Transmit ALC with long time-constant, pre-calculated power calibration, and virtually no dynamic artifacts: The K3's transmit ALC is, in effect, open-loop in relation to keying waveform rise/fall timing. In other words, we do not apply power corrections over short periods, since this can distort the keying envelope. This is especially noticeable in CW mode but applies to T/R switching in other modes as well. 3. Conversion to a low I.F., with both RX and TX signals running through a narrow crystal filter: This band-limits I.F. noise from early stages (DSP and D-to-A converter) and helps establish a very low transmit noise floor ahead of the main mixer. Even in speech modes, all fast ALC is applied ahead of the crystal filter, which I believe is unique to the K3. 4. Sigmoidal keying waveform applied at the DSP: Our DSP engineer (Lyle Johnson, KK7P) studied the sidebands resulting from various sigmoidal and raise-cosine modulation envelopes. He selected the one that provided the smallest keying bandwidth consistent with rise and fall times of approximately 4 ms. One clarification. The reason we created the K3's "QRQ mode" was to provide faster full break-in at very high code speeds (up to 100 WPM). The keying dynamics and phase noise are the same with QRQ mode either on or off; they are not "soft" with QRQ mode on. The KPA500 amplifier also switches very fast, so it is fully compatible with either mode. 73, Wayne N6KR On Aug 31, 2014, at 3:40 PM, Jim Brown wrote: > On Sat,11/20/2010 12:48 PM, John, KI6WX wrote: >> The ARRL is aware of this issue.

Thanks Wayne. I was aware of some of this, but didn't want to show any more of your cards than you chose. Your comments will make a fine sidebar. 73, Jim K9YC From jim at audiosystemsgroup.com Sun Aug 31 23:23:10 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 31 Aug 2014 20:23:10 -0700 Subject: [Elecraft] FTDX5000 Design Flaw In-Reply-To: <5403E549.2070004@triconet.org> References: <34ABD50DDE994556A5C11CABC280631C@JohnCore2><4CE7F2F1.3090305@subich.com> <3FDB4AB2908A46E09A8B790CCDD23BC9@JohnCore2> <5403A455.1080206@audiosystemsgroup.com> <5403E549.2070004@triconet.org> Message-ID: <5403E69E.8010300@audiosystemsgroup.com> On Sun,8/31/2014 8:17 PM, Wes (N7WS) wrote: > This is why that on more than one occasion over the years I've said > (only semi-facetiously) that the two-tone testing of the receiver > portion of a transceiver should be performed using two other like > transceiver transmitters, running rated output power, as the two test > tones.

The crystal oven option helps stability.? Allow 30-minute warmup. 2.? Max power for JT65 is 10 watts, but cooling is inadequate.? I use a small muffin fan attached to the desktop that blows air under the XV144 and works perfectly.? The extra noise is imperceptible over the hurricane created by 4 fans that keep the 3CX800 amp from blowing up.? Again. 3.? My K3 has the high-stability oscillator, but no external reference.? This works fine. 4.? As I recall, the internal 2m module is not as stable as the XV144.? The output for continuous duty is much lower.? You will have more amp flexibility with the external XV144.? And it's fun to build. 5.? As Jim suggested, use the milliwatt output from the K3 for less heat inside the XV144. 6.? On one rare night I blew up both my external pre-amp and the backup--I could still hear the louder stations.? The NF of the XV144 is good, but an external pre-amp will help a lot.? My short 7/8" Heliax run helps, too.? 7.? For many EME'ers, initials are as important as new grids.? This means that even a lowly W6 will be in demand when you first get on the air.? You WILL have fun. 73 Eric WD6DBM Sent from Yahoo Mail on Android
