Re: [Elecraft] KX3 interal battery charger
Hi Erik, I do not have enough personal experience with these to provide a suggested guideline based on my own empirical results. Other readers of this thread may have that knowledge or know of references. I suspect that if one does not abuse their cells, and if the cells are all in good shape to begin with, that removing the cells every few months should suffice. When I install my KXBC3 I will test and charge a set of AA cells so I have a baseline set of stats on the cells. Then I will check them after a few cycles of use and test/charge to see how well they stayed balanced. If badly out of balance at that point, then frequent balancing (or selection of a few different cells for better matching) may be needed. I suspect they will work very well, however, with balancing needed only every few months - subject to how often they are charged and discharged. Sorry that I could not be of more help on this. Possibly others can weigh in for us.

Re: [Elecraft] K3 - P3 or LP-PAN comparison
NaP3 is not the only software required with LP-Pan. Most installations require LP-Bridge or some other software port sharing package to allow both NaP3 and a logging program to "share" control of the K3. Several logging packages fail to work properly with LP-Bridge to the point that their developers refuse to accept bug reports if LPB is running. The resource load of LP-Pan must include both NaP3 and LPB as well as the interference they cause to logging software. There is no such problem with the P3. 73, ...

Re: [Elecraft] K3 - panadapter or subreceiver
Phil and all, Yes, for diversity receive, the filters should be matched. In theory, the 8 pole filters should have zero offset, but in practice, they may have a small bit of an offset. The answer is to "compromise" - if you hear a WOW-WOW sound while listening to diversity, you should change the filter offsets a bit. until you eliminate the WOW-WOW. If you are using the SubRX only for RX of the DX in a split situation, there is no need to have matched filters - that operation is quite different than diversity operation. 73, Don W3FPR On 7/2/2012 10:50 PM, Phillip Shepard wrote: > My understanding is that diversity receive works best with matched receiver > topologies.

Re: [Elecraft] KX3 internal battery charger
Hi Ed, Terminology can be a tricky thing! So can the specifics of different battery types and how to charge them. You raise a number of excellent questions. In order to assist other readers who may not be as familiar with the topic, and to assure I am being clear, I will go in to some detail. -- Balance and Equalize I think we are using these two terms synonymously. Balancing chargers have access to each cell and during the charge cycle will send different amounts of energy to each cell so that each cell is properly "topped off" on its own. If a multi-cell pack is rapid charged, there is the risk of undercharging some cells (an inconvenience) and overcharging other cells (causing damage, and in some cases causing catastrophic failure). I suspect this is exactly the same as equalizing. I purchased my LiFePO4 packs and iCHarger 106B+ balancing charger from a vendor (EP Buddy) in the radio control model hobby, so that is why I picked up the "balance" term. One must/should use a balancing/equalizing charger when rapid charging a battery pack, especially when using extremely high charge rates. When slow charging, the balancing/equalizing function, though beneficial, is not required. -- Charging LiFePO4 Batteries When talking about charging batteries using this specific chemistry, one must clearly state if they are talking about charging a pack that has no internal electronics (for charge control and safety) or a pack that is set up with cells and a control board inside. The latter style is often configured as a drop in replacement for a traditional sealed lead acid (SLA) battery. I did not make that distinction in my earlier post in this thread, thus introducing the possibility of confusion. Some LiFePO4 batteries are the exact same size and shape as SLA batteries and are advertised as drop in replacements. These units have an internal charge controller that handles the actual charging of the cells, often (but not always) with balancing/equalizing capability included. Externally, the battery is connected to whatever was charging the original SLA in the application. Thus, an uninterruptible power supply, any application using a standard SLA charger, or a solar power application may gain the benefits of the LiFePO4 chemistry and still provide charging current/profile as if the battery is an SLA. The controller inside the battery does the "translation" to manage the actual LiFePO4 cells. In these types of applications, a "standard" solar charge controller (which is designed for lead acid batteries) may be used as is because the battery mimics an SLA. Some LifePO4 battery packs are just made up of cells only, have no control board, and must be charged by a system that is designed for this specific chemistry. Just as with any other type of battery, slow charging may be performed without balancing/equalizing and rapid charging does require balancing/equalizing. This is the type of pack I am using. They are supplied by EP Buddy, BuddiPople, and many others. Note that a LiFePO4 pack of the same nominal capacity as an SLA battery will have significantly more actual usable capacity within a single charge. SLA batteries have dramatically reduced life if discharged more than 50% of capacity and have significant voltage drop even at that point. LiFePO4 batteries on the other hand may be safely discharged much more (80% or more?) without damage or diminished life, while retaining almost full voltage until discharged about 80% or so. LiFePO4 also seem to have a significantly longer "shelf life" and "service life" than SLA batteries. Those who have experience with overall life of these types of batteries may wish to comment with their findings. -- Solar Charge Controllers There is nothing magic about solar charge controllers. They are like any other charger, except that they are designed to handle the wide voltage and current range presented by a solar panel or array. Just as with any type of charger, they must know the type of chemistry utilized by the battery so that the proper charge profile is used. It is commonly known that lead acid, NiMh, and Li-ion all use different charge profiles, so the proper type of charger (or solar charge controller) must be used with each. Just as with "standard" battery chargers, solar charge controllers are not all alike. Choose the proper type for your battery chemistry or battery pack profile. This isn't always made obvious to the prospective purchaser since, historically, most general purpose consumer solar applications involve SLA batteries. -- For the KX3 I plan to use the following portable power options and charging equipment/methods: Internal lithium primary cells (8 AA size Energizer L92 Ultimate Lithium) - Non-rechargeable - used only as emergency spares (Alkaline make very poor spares in this application, although due to their common availability are the ultimate spares of last resort.) Internal NiMh low self discharge (LSD) cells (8 AA size Eneloop XX nominal

Hi, I have for sale a "Jumbo 240DX" HF amplifier with Rx RF amp stage. It is in its original box. I just tested it on 10m (45watts out)through 160m (80w output) with 4.5watts drive. It says that it will do 240w PEP output at max drive. I am also including a filter board from a TS 440S. This has dc switched filters for all the ham bands and an SWR coupler on board. Easy to mount and daisy chain with the amplifier. I did not check the amp at high power but assume it is fine. It is about the same size and layout as an RF Concepts VHF 100w amplifier. Takes standard 13.5vDC input. Asking $250 plus shipping. Ok in QRZ.com Accept Pay Pal. It is a pretty amp in great condition that will add a lot of zing to your QRP signal when you need it.

Re: [Elecraft] K1 with a strange XFIL problem...
Bruce, There is nothing overtly associated with the selection of FL3 that *should* cause a lockup. The way the bandwidth is controlled is to vary the voltage of the XFIL/TONE signal from the D/A converter - front panel U2 and apply it to the varactors connected to the filter crystals. I suspect that you have a corrupt bit(s) in EEPROM. You will have to do all the VFO, SIG and other menu calibration steps, but you can try a Reset to Firmware Defaults - see page 57 of the K1 manual. But then I see that you have tried that - so perhaps a new firmware IC is in order - that is just a guess, but the best firmware troubleshooting tool is substitution. You could also try replacing Front Panel U2 and U3 along with U1. 73, Don W3FPR On 7/2/2012 5:36 PM, Bruce Beford wrote: > OK, folks. > Time to put on your thinking caps... > I just purchased a used K1.

Re: [Elecraft] K3 - panadapter or subreceiver
Hi Brian, Use of a sub RX does not require a second antenna. I've been using a sub RX to chase split DX since 1991 with one antenna. The only time a second antenna is necessary is if you want to use diversity reception or possibly for some cross band activity. Conversely, a sub RX is not required to utilize a second antenna. You can use a second antenna with the main RX with the addition of the optional KXV3A board. 73, Mike K2MK Brian Maynard wrote > > I thought this through and chose the P3.

Re: [Elecraft] K3 - panadapter or subreceiver
Robert, I have both the subRX and the panadapter, and I love and use both a lot. But if I had to choose between one or the other, I would definitely recommend the P3. I use the P3 all the time -- it is a revolutionary new way to interface with the radio. I just used it a moment ago to break a huge pile up trying to work 1A0C on 20M RTTY. I also use the panadaptor to view band openings and gage the general acitivity on the bands. When tunring the K3, I hardly ever look at the frequency readout anymore. I instead look at the P3 and move from one signal to another much faster. I do use the subRX, especially when I have to go split in a big pileup. But I don't use it nearly as much as the P3. I orginally bought my K3 without the subRX and was very comfortable going split with two VFOs. When I added the subRX, I quickly learned how to use it to listen and tune through a pile to find the station being worked or a gap in the pileup as a whole. But once I got the panadaptor, I don't have to listen on the sub RX nearly as much. The panadaptor allows me to see the pileup and move my VFO B frequency visually and much more quickly. So if I had to choose, I would vote for the P3. But the real answer is the two in combination are lights out! One final thought: if you are going to order your K3 factory built, it might make more sense to buy the subRX. It is a bit involved adding the subRX after the fact. It is super easy to add the P3 at any time. If you already have a K3, then it is a lot easier to add the P3. Eventually, you will want to have both. Dave, N4QS - Original Message - From: "Robert G.

Re: [Elecraft] K3 - panadapter or subreceiver
I'm a certified (or certifiable?) O.T. who has been haunting the Ham bands for over half a century, content to listen intently for signals while slowly cranking the main tuning knob. Panadapters have been around a long time, but I always thought "Huh! Who needs that sort of gadget?" Then came the P3. I'm addicted. It's worse than TV way back in the days when we'd sit around for hours watching the test pattern, but infinitely more useful! If I had to choose today, it'd be the P3 over the subrx without hesitation. BTW, like Craig I find it very useful for chasing RFI. 73, Ron AC7AC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - P3 or LP-PAN comparison
Robert, The Perseus SDR, which uses a computer for display and control purposes, performs very well as a panadapter, also as a multi mode receiver which covers 10 kHz to 40 MHz The maximum span which can be displayed is 1600 kHz, and the minimum span is 800 Hz. The resolution bandwidth is stated to be 1 (one) Hz when the span is set for 800 Hz, which allows one to see clearly a weak CW signal separated by 10 - 11 Hz from a very much stronger CW signal ( 50 - 60 db stronger) at the narrower scan settings. I have never run out of markers when attempting to deduce (using my Perseus) the listening pattern of a DX station in a pileup, if he/she is following some sort of listening pattern. The dimensions of this SDR are 4.25 x 1.5 x 7.5 inches, and it weighs 380 grams (sorry for mixing Imperial with Metric!). I have no financial interests related to this SDR. 73, Geoff LX2AO On July 02, 2012 at 8:01 PM, Robert G. Strickland wrote: > In another post I ask about sub-receiver versus panadapter.

Re: [Elecraft] K3 - panadapter or subreceiver
I have both with my K3. If I could have only one, it would definitely be the P3. The sub RX is great for diversity receive which helps a lot in CW contesting. But the P3, as other have pointed out, lets you quickly find where to place your signal when trying to find a good run frequency. For DXing, I think it is pretty much a tossup. But one aspect of the P3 that no one has recently mentioned is that it makes a SUPERB piece of test equipment when used with the K3. I don't have a dedicated spectrum analyzer but found that the P3 meets many of these needs. I use it when designing and characterizing filters. The ability to easily download and print out plots in full high resolution color is amazing. I often use it with the Elecraft noise source as an input signal. Of course I have the general coverage bandpass filters K3 option, which I highly recommend. And the K3's functionality as a calibrated tunable RF voltmeter is awesome as well. The P3 is also invaluable as a tool for tracking down EMI. You can see the type of signal and how it is moving in frequency vs. time. I use it for this both with the K3 and also as a portable battery powered standalone EMI receiver by setting the programmable IF frequency to the range of interest and using a small hand-held loop antenna. For anyone with an interest in home brewing and circuit design, I can't recommend the K3/P3 combo highly enough. 73 Craig AC0DS __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - panadapter or subreceiver
I'd agree. I never had either in the past and now I'm constantly looking at the P3 and I do use the sub-receiver but don't turn it on every time I'm on. The panadapter tells me when the band is dead, when my antenna is tuned properly (I have a magnetic loop that needs to be tuned all the time), when other stations are on, and also if the *%&# power line arcing is active on the pole outside my house (it's scheduled to be fixed, but it's been going on for months). I'm sure I could go back to doing things the old way, but it's like turning off DX spotting: why would I want to?

Re: [Elecraft] K3 - panadapter or subreceiver
I thought this through and chose the P3. The subRX requires a second antenna - which I did not have - and the matching filters, so it is not just the receiver alone. The P3 does everything the others have mentioned, and as one responder said - you will end up using it all the time if you work DX split. - Brian, op K1NW -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-panadapter-or-subreceiver-tp7558492p7558517.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - panadapter or subreceiver
Hi Robert, I have the sub RX and the P3 and I would not want to be without either, however, if I were trying to save money on an initial purchase I would buy the P3. The P3 is easy to use and is useful at all times under all conditions. The large screen SVGA option which I also have is nice but certainly not mandatory. The P3 in combination with the existing tools on the K3 will make working split very rewarding. The sub RX is wonderful but I can go weeks without every turning it on. But when needed it is a superb tool. However, working a split DX station where there are thousands of callers is still tedious. The sub RX in combination with the P3 is terrific. I would also say that a P3 is much more useful in a contest than a sub RX. I've operated many CW contests where I never turn on the sub RX but use the P3 extensively. However, if you have the opportunity to add a low noise receive antenna for the low bands then the sub RX can also be used for diversity reception. This is where you can listen to your transmit antenna in one ear and your receive antenna in the other ear.

Re: [Elecraft] 4.48 vs 4.51 CW Decode (my test)
Hi all, I know that this topic has more or less gone its way, but I just got a chance to try this out during the past weekend. I hadn't had much luck with decoding CW on the K3--usually a bunch of asterisks and "E"s and nothing else. However, I got new 700Hz filters a week ago or so and wanted to try them out and also was curious about what I had been reading. I do pretty good copying CW but when they start send 30wpm or so in contests I often have a lot of trouble copying DX callsigns from scratch. I originally tried copying from 4.48 but had no luck and could never get it to work, in spite of what I read in the posts. What a surprise I got from version 4.51!! It would read any strong signal without any trouble, even when there are other signals nearby. When I used tighter (700 or 400) filters or APF it was even better--just as Wayne and others had mentioned. No, it wouldn't copy EVERY character here at my very noisy location, but I found that it did help me verify what I "thought" I was hearing on the, for me, ultra-fast CW in this weekend's contests. I also downloaded and installed the latest version of MacLoggerDX, which now sports a CW reader for use with the K3, and it was excellent, recording the same characters that passed on the K3 screen with the addition of the ability to see at least 5 lines of code and at least some scroll-back. [not an ad for MacLoggerDX but think it is worthwhile noting] So, the new version gets my un-expert vote for a great improvement in this area. Keep up the good work, Elecraft! 73, Scott XE1/AA0AA; AA0AA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K1 with a strange XFIL problem...
OK, folks. Time to put on your thinking caps... I just purchased a used K1. Has NB, ATU and 4 band board, set for 7/10.1/14/21 MHz. All appears to be operating normally, except... When cycling through the crystal filter bandwidths from FL1-FL3, once FL3 is reached, all buttons become unresponsive. The VFO readout still works, but the MCU will not respond to any key presses. The filter does actually switch to the narrowest setting, based on the audio response. Cycling the power returns the rig to normal operation (on FL1), and all works fine again until trying to use FL3. About the only other anomaly I notice is what seems to be a louder pop in the speaker when switching in RIT or XIT than I remember from my last K1. I have not yet begun any troubleshooting (except for a full reset). Just thought I would poll the collective wisdom here before digging in. Actually, I'll be getting ready for Lobstercon over the next couple of days, so I don't know how much time I'll be able to commit until after the weekend. I'd appreciate any thoughts or ideas on this one.

Re: [Elecraft] KX3 Questions
I also had a situation where I was getting a string of dahs in the middle of transmission. At first I thought it may have been a sticky KXPD3 set too tight, but then the same thing happened using an external Begali paddle. The adhoc antenna feedline situation I was using was, let's just say, not ideal, and I was running a full 10W when the problem happened, so I then suspected RF was getting back into the radio. I replaced that jury-rigged antenna setup with some proper feedline and a balun, and have not had any problem since. 73, Matt VK2ACL On Jul 2, 2012 11:14 PM, "Sid Leben" wrote: > I received my KX3 a few days ago & we are getting acquainted.

Re: [Elecraft] K3 - panadapter or subreceiver
Standby for incoming, Robert.:-) My suggestion: Your K3 has two VFO's and will run them split. That's what you need for DX. Without the subRx, you have to press and hold the REV button to listen on your TX freq on VFO B in SPLIT. It reverts to VFO A when you let go. With the subRx, you can hear both frequencies, one in each ear if you have all the stereo stuff set up right. With the P3, you don't really need to listen to your TX frequency at all, you can see it at the VFO B cursor in SPLIT. If you're in the middle of the biggest part of the pile, it is obvious instantly, so move. DX Chasing With a P3 and No SubRX: Find the DX. If you can't hear him, find someone else. If you can copy him, tap A>B. Then hold it for SPLIT. On the P3, the VFO A cursor ["color A"] is on the DX. VFO B cursor ["color B"] is on top of it. Rotate the "Little Knob" and put VFO B somewhere in the pile, anywhere is OK, it really doesn't matter. Pile calls DX, DX finally calls someone. One [if you're fortunate] signal will pop up. Put VFO B on that signal. When DX sends TU, call him. It's almost too easy, takes longer to describe it than to get in the DX station's log. :-) The subRx has a number of uses, diversity reception being one, and there are others. However, your K3 will already "do DX" just fine, and a P3 will change your operating habits [and coefficient of fun] dramatically. I bought mine pretty much as a toy. It's all I watch now. When S&P in a contest, I no longer tune with the Big Knob, I use the SELECT knob on the P3, put MRKR A on each signal and tap the knob. The various markers and cursors on the P3 are different colors, I don't have any color vision so I don't know what colors they are, but I don't have any problem at all operating with the P3.

Once you have worked the easy ones, you'll find that just about every new one you'll need will be operating split. It is so much easier to snag the guy when you can listen on two frequencies at once. With 2 receivers, you can put the main on the DX and the sub, set to a wider passband (I use 2 Khz), on the pile. You hear the DX in your left ear, the calling stations in your right. Then with luck you can find the guy who's currently working the DX, get your signal on or near his frequency, and make your call. This same routine is even slicker if you have both the 2nd receiver and a panadapter. However, the panadapter by itself will not find the guy who's working the DX, because the pile never stops calling even during a QSO, so you'll see a bunch of spikes and you won't know which one is the station that the DX is listening to. Whatever you decide, good luck and good DX.

I do exactly what you do with MMTTY, WSJT, JT65-HF, RSK2K, and I've tried out several other programs. All work just fine. What CAN help with ANY digital mode is a better sound interface than the generic one that comes with your computer. The $30 Numark and $70 Tascam USB boxes both produce about twice as many WSJT decodes as the sound cards built into my Thinkpads, and they're fairly good as laptop sound cards go. The advantage of the Tascam is that it handles a wider range of levels than the Numark, so it's easier to interface with more radios, but they decode equally well. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

I'm mainly a contester, but I work some DX, digital modes on 160M, and all modes on 6M. I use the P3 a LOT more than I use the second RX. For DX, you get the overview of the pileup, can often see who he's answering, and can think about where you want to put your signal. For contesting, it helps fit yourself into a crowded band, see when someone is splattering or putting out garbage. For any operation, it's easy to quickly go to a band and check up to 200kHz of it for any signals. It's REALLY useful on bands like 10M and 6M, where signals appear for a few minutes and are gone due to E-skip. I keep the P3 full width (200 kHz) to look at 50.080 - 50.280. I've worked a lot of guys who were there for only a few minutes and gone, very common with 2-hop E-skip. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - P3 or LP-PAN comparison
N8LP on his website has a very comprehensive and IMHO honest comparison of P3 and LP-PAN. In snapshot, if you are strained on cash, good in computers, and occasional software problems are not an issue, use LP-PAN. If reliability and ability to change parameters fast via buttons are more important, P3 is good. I used SDR-IQ but eventually bought P3.

Re: [Elecraft] KX3 Questions
Had the same experiences with the keyer paddle KXPD3 ... a bit too much tension ( which is not adjustable except by surgery ) and the spacing is kinda tricky ( wound up having it wider than I like ). I also like a slightly wider paddle footprint ( someone suggested gluing/sticking something on them ). For FD, I didn't care for the way I sounded with it, so I reverted to the shack paddle, with great relief. I'm not exactly thrilled with it, considering the price, but I intend to hang onto it: for ultra portable, I can slow down. And for FD, it worked very well; contacts from all over, both coasts forgot it was a "QRP rig" ... plays "bigger". And I guess I'll have to take my IC7000 on my western trip ( yeah, and the manual too ... three years and I don't rememmer nuttin' ... can do a K3 or KX3 blindfolded ).

Re: [Elecraft] K3 sub receiver no signals
Hi Mike; I had the same problem a number of months ago and it was so frustrating I finally removed the sub rcvr and sent it off to Aptos. The guys there were very helpful as always but it came back with a perfectly clean bill of health as they could find nothing wrong with it. This was after I had checked and rechecked all of the cabling, configured all the antenna settings about a million times and pulled every last hair out of my head. Oh, yes, all the filter settings were fine from the get-go. When I reinstalled it after coming back from Elecraft the problem was still there; the sub was still virtually dead as far as the signals were (the audio level was always fine, just sounded like someone had switched in a -20db attenuator everytime I went with the SUB on. I believe what finally fixed it was a total reloading of the firmware and a recalibration of the VCO (IIRC). I also set every band's antenna selection regardless of whether or not the band was IN or OUT to MAIN (making sure that it stayed set on MAIN every time I checked the settings). Finally, just when I was about to throw in the towel, the SUB came back to life! While I'm not 100% sure I do believe it was one of the calibrations I performed (VCO calibtration or DSP utility) that did the trick in the nick of time. I have been a very happy camper ever since (despite not really knowing what caused the snafu in the first place; it suddenly went deaf while I was operating split and chasing a DX pileup...and oops!) and now I appreciate this little rig more than ever. I'm still scratching my head over it all but unless it happens again I may never really know the hows and whys... Reminds me of the old saying, "You never miss your signals until your sub-receiver dies!" Hope you get it going again right away and I suggest redoing ALL the calibrations required when the sub is first installed---that may very well bring it back to life. Best of luck to you (and I know just how you feel). 73, Jeff NH7RO -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-sub-receiver-no-signals-tp7558455p7558488.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX3 Questions
I have the same issues with my KXPD3. With maybe 100-125 CW qsos logged using the KX3 and KXPD3 I have now accepted the fact that I must compromise and use a more coarse paddle adjustment. I have also had issues with random dropping of the first "dah", which is further complicated when a "dah" is supposed to break up a string of "dits" as it does in iambic keying. I initially thought I had it fixed after cleaning the KXPD3 contacts with Deoxit and further adjustments, but the problem still surfaces occasionally. My sending becomes a bit embarrasing at times as a result. (not to imply that I have a "great" fist, which I do not) BUT, in my mind, the advantages of having the KXPD3 conveniently attached to the rig far outweigh these minor inconveniences. I bought my KX3 for portable operation, and am willing to accept the many compromises associated with that. Another minor KXPD3 issue The way the paddles themselves are machined there are sharp right angle margins adjacent to all of the finger and thumb contact areas. If those edges were rounded and smoothed moderately they would be much more comfortable to use .. In my hands at least.

Re: [Elecraft] KX3 Questions
If you read the KX3 Errata sheet (should have been supplied with the radio) on the web site, you'll note that several functions described in the manual are not availble as yet. And "NR" is among those. And, I agree with you on the paddles. Neat, but I can't get them adjusted like I would normally adjust my HEXKEY, tight. It also seems that they have more travel now then a week or so ago when I last adjusted them. I have resisted the temptation to disassemble and make the spring tighter or find a way to replace it with magnets. Until I see inside, I can't really make the decision, but I'm really leaning toward using magnets to provide the 'feel'. I've done this with others including a "AZQRP Scorpion". ...bill nr4c On Mon, 2 Jul 2012 07:51:49 -0700, Sid Leben wrote: > I received my KX3 a few days ago & we are getting acquainted. > Similar to my K3, but not the same.. > I downloaded the newest Beta, 1.06. > As I understand it, there is some form of DSP installed.

The radio is entirely based on digital signal processing (DSP). I understand that many people mean "automotaic filtering of some sort" when they use the term DSP. Those features -- noise reduction and automatic notch -- are actively being worked on as I write this. > The AGC left at the default Threshold of 7, is not sufficient.

With a high AGC threshold, this means a strong signal will overload the audio chain. If the gain is set so that a very strong signal doe snot overload, then a high AGC setting may be appropriate. It all depends on the ambient acoustic environment, the "band noise" at the moment, the efficiency of the audio transducer (internal speaker, headphones, external amplified speaker(s), etc) and your hearing comfort level. In general, you want the AGC to cut in above the band noise -- how much above depends on a lot of things and is usually dominated by your personal preferences. I usually have the AGC Threshold in my KX3 set to 5. > I am trying to use the APF mode. A little complex, but it tends to ring when > peaked in mode II. The APF will ring a bit by design. It is mostly used for helping to copy weak (that is, near the noise level, might be S6!) CW signals at slow to moderate keying speeds. It is not the appropriate filter for fast CW, or for signals with reasonable S/N. The regular filtering (accessed by turning the PBT control) is appropriate for the latter cases. I see you've had good comments on the KXPD3. Enjoy your new radio, and thank you for your observations! 73, Lyle KK7P __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX3 Questions
Yes, there is extensive DSP in this radio. However, the NR is not yet implemented. Check the user manual errata (KX3 Owner's Manual Errata Rev B4-1 - June 1, 2012) on the Elecraft web site for details on firmware enhancements still to come. For example, the NB, though implemented can only be set on or off right now - levels will be provided later - and some other features are also on the "to do" list. When planning to use APF, be sure to first turn on CWT, then tune the signal as close to the center of the indicator as is reasonably possible (it doesn't have to be exact, however), then SPOT the signal, then set a fairly narrow bandwidth, then turn on APF. Experiment with it! It is pretty cool! 72/73 de JP WF4Z On Mon, Jul 2, 2012 at 10:51 AM, Sid Leben wrote: > I received my KX3 a few days ago & we are getting acquainted.

[Elecraft] K3 sub receiver no signals solved!
There was a config error in the Sub filter setup. I have a 2.7 filter in slot 2 and 400 in slot 4. Those were setup correctly. The Sub also thought I had a 2.7 in FL1. Changed that and the receiver came to life. Obviously the other issue was that I had decided, for reasons still unknown to me today, to install the input using the AUX BNC. Thanks for the suggestions and hints! We are fortunate to have some very smart helpful folks on the reflector!

Re: [Elecraft] KX3 internal battery charger
I went ahead and ordered the internal charger so that I have the clock and so that I can keep a set of Eneloop XX batteries healthy inside the radio for ultralight operations. I, too, am interested in solar charging of my LiFePO4 packs. If one feeds raw solar panel power to a battery, then things get "exciting" to a degree, depending on what kind of battery is involved. I will defer to those who have actual field experience as to when that is or is not advisable. BuddiPole now offers a solar charge controller for LiFePO4 battery packs. It is $45.00 and charges the entire pack but is not a balancing charger. It is small and compact for field use. One will want to periodically test and balance their packs with a balancing charger. http://www.buddipole.com/sobaco.html An untested idea of mine (though I'm certainly not the first person to think of it) is to feed a standard balancing charger with power from a solar panel - as long as there is sufficient current and the voltage ranges are compatible - or using a DC-to-DC device between the panel and charger to maintain a steady voltage into the balancing charger. This is certainly more moving parts and more weight. Again, I will defer to those with actual field experience. Is this efficient? Is it practical? Has anyone done this already and can report findings? I suspect that for both the internal NiMh cells and the external 4SxP LiFePO4 packs, a simple charger for field use and a smart charger for bench use, will provide the best of both worlds. Food for thought... and experimentation! 72/73 de JP WF4Z On Mon, Jul 2, 2012 at 3:38 AM, Holger Schurig wrote: > I also wondered about the NiMH stuff, now that LiFePO4 is affordable. > Currently I'd like to go with an external LiFePO4 pack as well.

Re: [Elecraft] KX3 Questions
Sid, Regarding your KXPD3, I have had similar experiences. I, too, prefer small gap spacing and also had the same experiences that you did regarding a string of dits or dahs. I may be imagining this, but I think it may have to do with thermal expansion / contraction of the metal components. I think I can correlate paddle performance at tight gap spacing with temperature changes. My shack tends to cool off overnight when my equipment is off and the HVAC gets ahead of the heat load. Then during the day it heats up. I should probably get out my feeler gauges and prove or disprove my theory. But, I now have a gap setting that works 24/7. It is a bit wider than I'd like, but I have adapted easily and I really like the KXPD3. When you're outdoors this afternoon, maybe you can detect the same thermal effects that I experienced. Good luck and stay cool! 73, BILL GERTH, W4RK Jefferson City, MO First Licensed 1954 CWOPS #459 KX3 (S/N 112) On Jul 2, 2012, at 9:51 AM, Sid Leben wrote: > I received my KX3 a few days ago & we are getting acquainted. > Similar to my K3, but not the same.. > I downloaded the newest Beta, 1.06. > As I understand it, there is some form of DSP installed.

[Elecraft] KX1 ATU low power
Just finished the ATU module for the KX1. Relays all work and swr into the DL1 is r 1.0 on all bands. Power output though is limited to about 2 watts per the display. Minus the the ATU, the W1 says I am getting 3 watts into the DL1 on all bands except 80M where it is 4 watts. Regulated bench power supply set at 12 volts. I guess that I would expect better concurrence between the W1 and the ATU. So not sure which one is off. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX1-ATU-low-power-tp7558478.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 Macro query
Hi Mike, I now have my macro working, but I don't know why. The only difference is that instead of assigning to M1H SET, I followed your example and assigned it to M1T SET. It would appear that there is some conflict between a function key Hold and a function that uses Hold. Assigning to Tap makes it work. Very strange...

[Elecraft] KX3 Questions
I received my KX3 a few days ago & we are getting acquainted. Similar to my K3, but not the same.. I downloaded the newest Beta, 1.06. As I understand it, there is some form of DSP installed. When I invoke "NR" the screen reads "tbd" I assume that more is to come, as there are no levels to adjust as in the K3. The AGC left at the default Threshold of 7, is not sufficient. I will try lower levels to stop the overload from strong stations. I am trying to use the APF mode. A little complex, but it tends to ring when peaked in mode II. XPD3 paddle. Mechanically a very nice match to the rig. I prefer a tight (little movement ) paddle. I adjusted the paddles until constant contact & then backed off, then tightened. Still more movement then I like, but I can acclimate. Sometimes in the middle of a transmission, I would get a string of dits or dahs, generally happens when settings too tight. I have opened the settings more, inducing more travel, & I still get the "stuck" condition. I am wondering if this is a mechanical problem with the key, or a software pblm with the encoder circuit I will take it portable this afternoon & give it a workout. I would appreciate comments.

Re: [Elecraft] K2 NB LEVEL question
Stan, The Noise Blanker is only effective on fast rise time noise pulses - like automotive ignition noise. It will do nothing to reduce noises like atmospheric noise or powerline noise. If you want to test it, remove the antenna, turn on the preamp and tap a screwdriver on Q22. You will have to differentiate between the bursts of atmospheric noise (the screwdriver is acting as a short antenna) and the "clicks". The NB should kill the clicks, but will not change the atmospheric noise. 73, Don W3FPR On 7/2/2012 1:11 AM, ae7...@gmail.com wrote: > Don thanks so much for the quick reply. > The 4 different "modes" seem to be the same with NB1 or NB2. > Also if I have the NB OFF. > > Thanks again. > Stan AE7UT > > -- > View this message in context: > http://elecraft.365791.n2.nabble.com/K2-NB-LEVEL-question-tp7558461p7558465.html > Sent from the Elecraft mailing list archive at Nabble.com. > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 sub receiver no signals
Hi Mike, Is it dead-dead or do you get audio noise when turning the audio/rf gain. If it is dead-dead it might be the l-mix-r setting to a-a or something other than a-b. Also, if you have SPKRS=2 and are listening with the internal speaker you get the main audio only. Hope you find it.

[Elecraft] K3 Macro query
The following macro runs OK from the K3 Utility program, but not when assigned to a function key - why ?

Re: [Elecraft] K3 sub receiver no signals
Hi Mike, This question comes up quite often on the reflector and it is usually incorrect antenna selection as others have commented. But there are also several other things that could be amiss. You could have the RF gain for the sub turned down. It's the outer ring on the RF gain knob. Assuming that you are using headphones you should also check to see how you have the audio gain knobs set up. They can be configured so that the outer AF knob is a sub volume control or configured so that it is a left/right balance control. Another thought is that you have the sub RX filters configured incorrectly. You could also have the sub set up in diversity mode. In diversity you'll be listening to VFO A in both ears regardless of what is displayed in VFO B. The tip off is a blinking decimal point (the right decimal point) in the VFO A display. 73, Mike K2MK w0mu wrote > > I installed this 2nd receiver quite some time ago.
