[Elecraft] K3 Delta-f Indicator not working
All, I have a relatively new K3, firmware version 4.39. When setting split around 10.110 MHz CW, I noticed the amber delta-f indicator not lighting when entering split mode. The unit clearly showed split mode on LCD display with the TX pointing to the secondary frequency, with TX frequency a few kHz up the band. I had been trying to dig an extremely weak signal out of the noise, and had disabled the subreceiver briefly to try to pick up a little extra gain. I don¹t remember if the light had actually ever lit. As a test, I enabled RIT and XIT. The indicators around that encoder worked, but still not delta-f below the power button. I was able to restore functionality to the delta-f indicator when power cycling the K3. Having been a former Kenwood user, I¹m used to having the display frequency change on transmit in split mode, so not sure really split is working or not when this indicator does not work. Sometimes I forget to disable split when done with it and embarrass myself, so I need all the help I can get! Any ideas? (No running PC attached to K3 at the time, so HRD or other logging S/W not an issue this time around. I do have P3 with latest F/W attached.)

ANTHONY JAPHA wrote: I'd like to add a similar suggestion, this one about the APF in the K3. I accept that it works as intended, but it is not useful. I've used APFs for many years and they can be very useful. The need to severely narrow the bandwith to avoid ringing and the poor peak in the audio when the APF is peaked limit the current filter. What I'd like to see is an APF that does not depend on a narrow bandwidth and that has a pronounced (tunable) peak at the desired frequency. It does not need to be extremely sharp, but it could be if that is dictated by design considerations. And, to keep it simple, there also does not need to be a choice of bandwidth through the menu, I'd like to hear others' ideas. I'm confused about what you wrote. Are you in *APF* or *nor* in CONFIG: DUAL PB? If you don't like APF then try the normal DUAL PB function. I'm not sure which APF you've used for many years but the K3's APF emulates what is generally accepted to be the best APF ever implemented (FT-1000D's original design, not the later update): http://lists.contesting.com/archives//html/Topband/2000-03/msg00025.html I very rarely use APF unless the situation demands it. It makes no sense to use when signals are Q5. What is does very well is to extract weak signals from the noise floor. However it requires *extremely* careful tuning (either using the 5 Hz SHIFT steps or VFO FINE 1 Hz steps). When H40KJ was recently on 160m, he was very weak here in the South (propagation seemed to be favoring stations in W2 and W3). I used APF every time he was on and was able to copy him most days but he had no RX antenna so he couldn't hear me in the poor propagation. Finally he was able to hear me with difficulty on the last day of his operation. I believe there were only 2 stations South of Virginia to work him and I was one of them thanks to APF. Difficulty of receiving shows case of Bill W4ZV, his signal was relatively strong with no QSB, but to make me sure about his call sign took me seven minutes!!! Only thing I was sure from begening was W4, rest of the call, just two letters was ureadable, ZM, ZF, MF could copy this in many ways. So W4ZV is an easy call so what you say about WB6RSE?? http://lists.contesting.com/archives//html/Topband/2011-11/msg00020.html 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/NB-and-NR-algorhythm-tp6990987p6995998.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] Buzz
Thanks Jim for the battery suggestion. I have tried several means of supply voltage. Straight from a battery, battery with PWRgate, linear power supply that can vary votage from 13.3 to 14.9, switching power supply at 13.8 to 14.x. The buzz varies from fairly slow at the lower voltage, increasing as voltage is increased until 13.9 where it pulses at about two or three per second. When voltage is increased, it speeds up and then stops completely at 14.1 volts. Receiving audio varies in volume, low to high and distorts as it is increased to maximum. I suspect all of this problem is in the audio circuits somewhere. I'm not sure if there is an individual audio board in the radio or not that could be replaced. I suspect it will need test equipment to find the problem as it is probably unique to my K-3. I am waiting for the support folks to respond with suggestions but I really think it will have to go on the bench at Elecraft. 73, GriffN5AG __ 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] SDR-IF and I/Q questions
Dick, if some programs work, then your levels may be low. PowerSDR/IF and NaP3 use an algorithm developed by Flex Radio called WBIR (Wide Band Image Rejection). It does a phenomenal job of eliminating images (80dB) but is sensitive to levels, requiring a minimum amount of total signal power in the display to work. Since you say that other programs work, your issue may be levels. Most SDR users have no trouble with this, but there are stubborn cases like yours that pop up. They are usually related to sound card drivers or other system settings... or even bad cables. I had one customer who sent me his whole setup, and I found that his new cables from Radio Shack had about 10 ohms resistance between center pin and shield. There are tens of thousands of SDR users out there who are successfully using them, so these things can be solved. Pete and I have been talking about an indicator for NaP3 that would graphically display the overall balance of the sound card channels as a way to verify that the channels are matched within the range necessary for WBIR to work, but this would take some thought... and work. It would be worthwhile, though, for the percentage of users with stubborn image issues. One very simple program, that provides all the features of the P3 except fixed tune mode, is TRX-Pan. It is extremely well integrated with the K3, and has a very simple manual image rejection adjustment (sliders for gain and phase). You set it once and forget it. There is no automatic learning needed and it will not change with levels or time. The tradeoff is that image rejection across the display will vary from about 60-80dB. Only the very strongest signal (S9+30dB or more) would produce an image, and it would be 60-80dB weaker than the signal. Since the adjustment is manual, you can easily tell if your sound card has a problem, and make external adjustments while watching the image for changes. TRX-Pan requires LP-Bridge or TRX-Manager as the link between the rig and software. It is very easy to set up, especially with LP-Bridge. Everything you need can be found here... http://www.telepostinc.com/TRXP.html 73, Larry N8LP On 11/15/2011 3:53 AM, elecraft-requ...@mailman.qth.net wrote: Date: Mon, 14 Nov 2011 12:42:41 -0600 From: Richard Fjeldrpfj...@embarqmail.com Subject: [Elecraft] SDR-IF and I/Q questions To: elecraft postingelecraft@mailman.qth.net Message-ID:20779EE975F7478494FA31FC637B8D30@BIOSTAR Content-Type: text/plain; charset=Windows-1252 Well Dave, maybe I am missing something here, but this thread has been about the anticipated KX3 and having a Pan-Adapter to use with it. As I understand it, the I/Q leads are being brought out, but not the IF. So other SDR receivers, or adapters, are not needed. Therefore, we are down to finding acceptable software, soundcards, and computers to make it work on a par with a P3. The programs I tried that are not producing mirrored images are lacking good control between radio and software. No 'search and pounce' capability, and time consuming to adjust as the frequency was changed beyond the display width. Not hardly on a par with a P3. Perhaps there is something out there that I am not aware of. I'll concede that, but if it is a commercial product, I want to exercise 'buyer beware'. I find PSDR-IF would be a very good match if it wasn't for the mirrored images that fills a crowded screen.

[Elecraft] KPA500 audio muffled?
I have gotten a few reports of sounding like my audio is muffled as compared to running the K3 alone. It is true that with several listeners in different states, there is not a consensus of opinion on that. Some of the guys think it sounds just fine, and some say they can hear a slight muffled sound with the KPA turned on. The point of comparing it to K3 only and K3 with KPA500 is that the mic is not in the equation. The report is clearly that the amp sounds muffled. Not unreadable, just slightly muffled. I have a bias current of 0.4A...about the only thing I can think of to check. I think there was some discussion of setting the bias current here, but I can't find it again. What is the range of bias current for best linearity? I don't see any help in the manual. - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-audio-muffled-tp6996649p6996649.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] OT: Wind Loading on Antennas - insight from da Vinci
This is 'way off topic except for Elecrafters who home-brew antennas. I apologize for using the bandwidth. While antenna home brewers are primarily concerned with electrical performance of various antenna designs, we also must take into consideration the physical strength of the antenna, particularly with respect to wind loading. For example, just how beefy do we need to make the boom on a long Yagi? And what taper schedule optimizes for strength vs. weight? There's an interesting article posted online about tree growth, at http://www.wired.com/wiredscience/2011/11/branching-tree-physics/?utm_source=feedburnerutm_medium=feedutm_campaign=Feed%3A+wired%2Findex+%28Wired%3A+Index+3+%28Top+Stories+2%29%29utm_content=Google+Feedfetcher which tangentially touches upon this question. The article goes back to an observation by Leonardo da Vinci that tree limbs grow to a certain diameter -- roughly speaking, when a trunk splits into multiple branches, the sum of the diameters of the limbs equals the diameter of the trunk. Nobody ever figured out why trees grow like this, until now. A French mathematician has demonstrated that this is due to wind loading on the leaves. He modeled a tree as cantilevered beams assembled to form a fractal network. Antennas can be considered similarly, I hypothesize. It would take someone with more math capability than I have (as a former English major) to apply this thinking to antenna design, but I suspect that such analysis would suggest the most efficient taper schedules, for example, in building a Yagi. OK you engineering types, have at it!

Re: [Elecraft] K3 Noise Blanker and Noise Reduction
While I've never met a Noise Reduction implementation that I've liked on SSB, I'll confess to not had broad exposure to a lot of different ones. However, I'll join you in your finding on the Noise Blankers. I've only found the trade-off between Noise Blanking and distortion introduced to be occasionally satisfactory and then typically only at low level settings. One sign of hope is that the hardware blanker is on a separate plug-in board, though I don't recall every having seen any mention of design changes to that. As well, I find the Notch Filters less than satisfactory. The Manual Notch is not sharp.the bottom is flat and wide. The Auto-Notch often imparts Barrel-like acoustics which I find annoying. An email query about possible improvements to the Noise Blankers and Notch Filters sent to a member of the design team received no reply. In a rig designed to set the bar when it comes to 'the numbers,' it's a shame that the performance of these basic features of Noise Blanking and Notch Filtering is lacking. Is there yet hope? 73, Dick - KA5KKT --- Am I the only one who find it difficult to use the Noise Blanker and Noise Reduction controls on the K3? Maybe it can't be improved but it sure doesn't work as well as the Ft5000.

[Elecraft] Noise with KX1 and Powerwerx PS
Good Day Everyone, After reading some of the discussions regarding power supplies, I've recently bought a Powerwerx 30 amp switching power supply. I knew that this was way more than I needed for present needs, but I didn't want to under-buy and have to buy up later. Anyway, the unit supplies 4-5 watts indicated by the ATU, and I have an SWR of 1.0 to about 1.9 using the Elecraft rescommended antennas (This my only rig, and I use it from my desk). Here's the problem: Independent of band or frequency selected, I get a noise that sounds something like a small jet taking off or the whoosh that the dishwasher makes on wash cycle--WWWUUUSSSHh (Well, sort of like that.) The sound starts low and finishes high and then goes away briefly and then recurs fairly regularly. The noise isn't there when I use battery mode. Am I doing something wrong here, or is this the nature of this type of power supply?

Re: [Elecraft] KPA500 makes birdies on 6 meters
Hi Ed, Dale from our customer support group will be contacting you today to see if he can help you determine what is going on. I believe Bob Wolbert, our KPA500 engineering product manager, has also emailed you for more info. We do not see this noise on any of our KPA500s tested in production. Since we use a linear supply in the KPA500, there is nothing inside that should generate 140 kHz harmionics. This sounds suspiciously like a swithcing power supply, router wall wart etc. in the shack that is feeding into the rx system via a leaky coax or a coax with an open shield at one end. I've also run into this when the dummy load was coupling to the source of the noise. (Many dummy loads are not as well shielded as you may expect.) Try moving the dummy load (and coax cables) while watching the noise. If it varies, its an external source. You might also try swapping out the coax between the amp and dummy load, and between the K3 and the amp. Also, try disconnecting the coax from the amp output and see if the noise changes. (Lastly, if you are using a switching power supply, try substituting a linear supply or battery. Feel free to email dale and Bob any results you get from the above tests.

Re: [Elecraft] KPA500 audio muffled?
Thanks Eric on the voltage being normal. I thought I'd change things to possibly get some more data on what it is not, and at least keep the pilot lights on the 120vac strip from blinking slightly. There was also a comment on my email (but hasn't appeared here) that I should look into RF getting into my mic input. I am doing that and I know that I have some RF floating around here having gotten into the pc monitor, etc. I like that as a possibility although these critics I mentioned are very good at recognizing RF in the audio. But maybe just a tad can produce the results they seem to have noticed. And the correlation with higher power is obvious.

Can CW be sent via CAT or do I need a special cable/circuit to accomplish this? The default port is 3F8 btw. 73, Casey, TI2/NA7U - Costa Rica Blog -- View this message in context: http://elecraft.365791.n2.nabble.com/How-do-you-get-N1MM-to-send-CW-to-the-K2-tp6997489p6997489.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] KPA500 audio muffled?
Chuck I agree with Joe's diagnosis. Try an experiment:- Run 100w from the K3 alone and get a report. Then turn back the power so that K3 plus amplifier is producing 100w. See if the report is now OK, or muffled. If the report is OK, it could be RF feedback which only occurs at high power. If the report is muffled you might have an amplifier problem.

Chuck, I had muffled audio reports while using a Tokyo Hi Power 1.2Kfx amp. It has coming from RF getting into the amp. THP wrote it off, saying nothing they could (would) do about it because I was on the second floor. But... I now have a KPA-500 and have no problems on any band at any power level. Just a thought! Joe N9VX I have gotten a few reports of sounding like my audio is muffled as compared to running the K3 alone. It is true that with several listeners in different states, there is not a consensus of opinion on that. Some of the guys think it sounds just fine, and some say they can hear a slight muffled sound with the KPA turned on. The point of comparing it to K3 only and K3 with KPA500 is that the mic is not in the equation. The report is clearly that the amp sounds muffled. Not unreadable, just slightly muffled. I have a bias current of 0.4A...about the only thing I can think of to check. I think there was some discussion of setting the bias current here, but I can't find it again. What is the range of bias current for best linearity?

[Elecraft] K3 deaf on 10 meters
Hello list, My K3, serial number 3953, hears only the strongest signals on 10 meters. I observe that the noise floor displayed on the P3 is around -140 db. Switching the antenna in and out does not change this reading. On the lower bands I see a noise floor change. It's like the antenna isn't being attached. The transmitter works on 10 meters with an 1:1 swr. The pre amp moves the noise floor as I expected. Any suggestions?

[Elecraft] used K2 Alignment
Hello; While I am generally thrilled with my new K2 (not built by me) I feel she is in need of an alignment touch-up. The rig used to have all the bells and whistles but now is CW only with no tuner, SSB, etc. It is pretty much on with alignment but not exactly. The one thing that definately bothers me is one filter width - 700hz - causes the received signal to change in pitch. The other settings leave it unchanged. Also, I'm never on a cardinal freq when I work people - and I'm sure some of them are on whole frequencies - like 7.030.0 or 14.050.5. I'd like to get this thing closer. How best to proceed? I'm looking in the manual but I'm now a little afraid. I have ordered the 2 required probe kits for alignment but do not have the serial interface. Any ideas on how long this process will take and whether or not a neophyte should worry about rendering the rig useless? 73; Jacob K4JQV __ 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] SDR-IF and I/Q questions
Larry, Thank you for the suggestion. That could be possible. I'd hate to remove the Z10,000 Buffer/Amp to change out a SMD component, but that may be what I will have to do. My Z10,000 is set for 0 dB gain at present. I just e-mailed the Google PSDR-IF group a question about an observation I have made. It may be totally in the wrong pew, but you may want to look for it. And, it may reveal something I am doing wrong. Thanks, Dick, n0ce _ Dick, if some programs work, then your levels may be low. PowerSDR/IF and NaP3 use an algorithm developed by Flex Radio called WBIR (Wide Band Image Rejection). It does a phenomenal job of eliminating images (80dB) but is sensitive to levels, requiring a minimum amount of total signal power in the display to work. Since you say that other programs work, your issue may be levels. _- __ 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] used K2 Alignment
Jacob, You can do the alignment just fine. If it is mostly dial calibration and filter alignment that concern you, take a look at the K2 Dial Calibration article on my website www.w3fpr.com - that article also covers the filter alignment. If you do not have Spectrogram or some other audio spectrum analyzer, download it and use it to give you the easiest method of determining your actual filter width, shape and its positioning in the IF passband. If the pitch shift continues after the filter alignment, then there may be something stuck in the EEPROM - clearing it may require a Master Reset - but before you do that, download the A to B upgrade instructions from the Elecraft website because it contains a nice set of labeled blanks where you can record your menu settings. Record ALL the menu settings before doing the Master Reset and restore them afterward. The reset puts your filters and everything else back to the defaults. If you want to do a complete alignment of that K2, you may want to download the extract of the K2 manual that I have on my website too - it is the Rev E manual with the assembly steps removed leaving the alignment information intact. Note that the manual instructions will give you workable filters, but they are not optimized - use the instructions in the Dial Calibration article to optimize the filters. 73, Don W3FPR On 11/15/2011 2:13 PM, jacob chambers wrote: Hello; While I am generally thrilled with my new K2 (not built by me) I feel she is in need of an alignment touch-up.

Re: [Elecraft] used K2 Alignment
Jacob The high bands may be difficult to pre-align without a signal generator. I speak from experience from building SN 7105. I thought I had something wrong with my soldering when I discovered the rig deaf and dumb on 10 and 12 meters when all it was was a poor job of alignment using atmospheric noise. A friend who had a signal generator helped me discover that the soldering was fine, I just had not peaked the bandpass filters on alignment. He had a signal generator to help me do a first pass alignment. I obtained an XG3 and realigned the entire bandpass filter section and also aligned the S-meter for S9 at 50 microvolts. It can be done with sensitive ears but it is iffy. Others can voice their opinion but I found the XG3 to be a worthwhile tool to have.

I have a K3 with a SoftRock Lite II IF receiver , and I have to use SDR-1000 in the setup. When I do the Image Rejection Calibration, I notice the software tunes my radio to WWV at 10 MHz, and then changes it to 9.982 MHz. It looks like it is trying to calibrate for the SDR-1000, but the SoftRock has a 24 KHz offset. Could this be the problem, or not? I set things up according to the best info I could find at the time.

[Elecraft] SDR-IF and I/Q questions
Dave, I can see your point. One of my earlier posts referred to the problem of finding an acceptable arrangement to have a pan-adapter for a KX3 using the I/Q leads, as the IF isn't brought out. I apologize for not making that distinction in the subject line. That may have thrown others off as well. However, I am using a SoftRock receiver with a K3, so I have many of the same problems as we would have with the KX3, only it would not need the SoftRock. I don't like to express my likes and dis-likes, but since you asked, I will give you my personal opinion about the following programs. Others may dis-agree. Please don't sent me hate mail. You asked about NaP3. Yes, I tried it, and yes I like it, however I have the same mirrored image problem as I do with PSDR-IF as they are similar. YMMV. I think I have tried everything I could find that would be an acceptable matchup, thinking of it for a KX3. I was trying to find something similar to having a P3 in quality. You mentioned TRX-Pan. Yes, I tried it. I should maybe give it another try, but I was not impressed with how it looked. Perhaps I could get used to it. As I remember, it had a big spike in the center which seemed larger than that of WinRad. WinRad and HDSDR, are very sensitive on receive, and have no images. If WinRad provides control, I did not have info on how to use it. HDSDR does, using OmniRig, but control quit working after awhile. Perhaps I did not have time to learn how to set it up properly. One thing I did not like is that it seems to only look upward in spectrum from where the radio is tuned to. But it has other pluses. Both programs show the phase angle, and they record as well. The ZAP feature is nice for cw. Rocky works, but I find it to be more of a tool. It displays the signal strength of the L and R signals (I/Q). That is useful. Rocky can be used, but still not like a P3. I tried SDR-Radio also. I think it may be new in the offering, and more developments may coming. Like HRD, it has many add-ons. It wasn't what I was looking for, but a consideration. All during this time, I have been preparing to give a presentation on SDR to our local club, so could not devote a lot of time to each one, and it would be nice if that was not necessary. Unlike plug and play. I agree with your intended use. I know that SDR offers advantages, but if you have a K3, you will be satisfied with it's performance. Some of the comments I received seemed to be polarized with my appreciation of the P3. The main beef seems to be the screen size. It sure has been adequate for these old eyes. It is plug and play, and fast to use. I have it programmed up for quick button selections for the way I operate, and I like it. If the screen was larger, it would not match the radio. Yes, the addition of a monitor will be nice. I hope we don't lose the ability of looking at the P3 screen when a monitor is used, but we can't expect to have everything. Time will tell. SDR is fun to play around with as a learning tool, and will be rewarding to achieve a beautiful pan-adapter. When I said I was giving up on SDR, I should have said 'for now', as I spoke of the need to correct the problem of mirrored images.It is not just me, as many are having that problem. I was trying to find a pattern among those users who were either successful, or unsuccessful. I didn't get the info I requested. 73, Dick, n0ce The thread title didn't say anything about being restricted to the KX3, and your comment simply stated that you were giving up on SDR in general ... hence my comment. Whatever rig you've been having your problems with (I assume a K3), it certainly wasn't a KX3. I'm curious which programs you have tried that didn't have good rig control. Do you include TRX-Pan and NaP3 in that group? I'm interested because those are the programs I intend to try with my K3. By the way, my intended use would be for spectrum display and point/click QSY. I'm perfectly happy to rely on the rig for actual reception, filtering, demodulation, gain control, etc. Your needs may be different than mine.

Re: [Elecraft] K2 No power on 12m
Robert, Is this a newly built K2 or has it worked before? If newly built, it may just be the adjustment of the bandpass filter trimmers. If it worked before, does 10 meters work and produce full power output? If so, it may be an adjustment problem (or soldering problem) on C44 and C46, but if 10 meters does not also work normally, there is a problem with either the 10/12m bandpass filter or the 10/12m Low Pass Filter. Is this a failure with a dummy load connected? or with an antenna - it could be antenna problems, try into a dummy load. What measurement equipment do you have? If you have the RF Probe (or an oscilloscope with a 10X probe), you can do some signal tracing to determine the failure point. Do you have an external wattmeter that you can put between the K2 and the dummy load? 73, Don W3FPR On 11/15/2011 4:58 PM, Robert Clutson wrote: My K2 shows no bargraph deflection on 12m transmit.

[Elecraft] Split-mode problem
I have a weird one here. Intermittently, when I put my K3 into split mode, with the VFO A in SSB, the VFO B will turn up in CW or FM mode. In all cases I remember, VFO B was last in SSB mode, so the mode change happens when the Split is executed. Usually, I set the split within MacLoggerDX, my logging program. It is quite intermittent, so I have not used the front panel controls to set split. My K3 is only in CW when I am tuning a remote tuner, and only in FM on the rare occasion there is DX in the upper 10M band. Both occasions would be using VFO A. I do NOT have a second RX installed. I sent a console log the the logging software developer, and he was at a loss to explain the problem from an application perspective. I assume it is in the K3 somewhere, maybe an config setting that I messed up by accident. I am not a heavy K3 user, so I may have overlooked something simple. I would estimate the problem happens 20% of the time I go to Split mode. I have decreased the Comm port speed, to no avail.

Re: [Elecraft] Split-mode problem
Randy, I think that is normal operation if you simply turn on SPLIT without doing anything additional. If VFO B is not in the same mode as VFO A, you will transmit with whatever mode VFO B had been set for. Yes, VFO A and VFO B can be in different modes. The normal complete procedure for entering SPLIT (unless you know you have the VFO B mode, frequency, etc set up beforehand) is to tap AB twice (once only copies the frequency, twice also copies mode, etc.) and then move VFO B to the split frequency, then finally tap SPLIT. I don't know what the details of your MacLogger macros that you are using actually accomplish, but they can likely be created to do all the above actions in one macro. The information about how to set them up should be in the MacLogger help file for its end and the K3 Programmer's reference for the K3 part of it (which commands to enter and in what order). 73, Don W3FPR On 11/15/2011 6:10 PM, Randy Cook wrote: I have a weird one here.

[Elecraft] KAT500
I believe the K3/KAT500 will be similar to the K2/KAT100-1. Surely the KAT500 will have a retractable bale similar to the KAT100-1. This will mean the K Line components will not line up at the same height. I believe Wayne means for the tuner to be placed UNDER the K3 or KPA500. I would not place the KAT500 on top of the KPA500 restricting air flow to the amp, nor would I place it on top of the K3 restricting the sound from the K3 speaker (if the internal speaker is used). Does the KAT500 have a bale? Roy Morris W4WFB The KAT500 matches the K3/KPA500 footprint, but it's very thin (1.5 -- same height as the W2 wattmeter). You'll be able to place the KAT500 on top of either the K3 or KPA500. 73, Wayne N6KR __ 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] How do you get N1MM to send CW to the K2?
You will have to use a different com port on the computer which goes to a level converter circuit. That in turn will need to go to the K2's key jack. There is no way with a K2 to use RTS or DTR for PTT and CW keying as on the K3. DTR and RTS are not recognized on the K2, with those pins in the DB9 jack used for proprietary purposes, including the K2's internal bus. There are also issues with direct keying from a PC, usually irregular spacing or what some call jumpy CW. This is caused by a PC's multitasking. A lot of us, including myself, have gotten around all of this by using a Winkey box, or a utility box that embeds the Winkey chip. Microham devices embed the Winkey chip. N1MM can be told to look for a winkey device on the end of a com port, and will properly drive it.

Re: [Elecraft] How do you get N1MM to send CW to the K2?
What I did with my K2 was disconnect the ALC input line to the DB9 and use that for DTR, since even if I did operate SSB I would not use ALC! I connected this pin through a 1k resistor to a the base of an NPN transistor, grounded the emitter and connected the collector to a pair of diodes which go to the dit and dah lines of the K2's key input. Then I turned the autodetect feature ON in the K2, and set N1MM for DTR keying. The radio works normally with either a paddle or a straight key as well as the computer, and no extra wires or keying interfaces to the computer are required. It was very easy to hook up, and it was possible to route DTR through the same connectors from the KIO2 to the Control board and onto the RF board.

[Elecraft] K3 and Icom IC-2KL linear
Has anyone used the K3 with an Icom IC-2KL linear? I am curious as to whether you connected the ALC from the linear to the K3 or used the K3 without the ALC connected. __ 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] How do you get N1MM to send CW to the K2?
I would like to point out that Vic's solution will require an extra wire in the special cable that is constructed for the K2 to com port. The normal cable carries only the RXD and TXD signals (plus signal ground) - there is no wire for DTR (or alternately RTS). While Vic's solution can work (and work as well as any DTR keying from a computer), it is not something to be attempted by those unfamiliar with the internal K2 signals present at the DB-9 connector nor those unfamiliar with RS-232 signal lines and the one transistor keying interface. If you understood and followed all of that, yes, you can do it too - but if you did not understand those skimpy instructions, be aware that you can damage you K2 if you do not understand the signals involved. This is not a modification that can be installed willy-nilly, it must be done with care to divorce the normal K2 signals to the DB-9 connector and add the keying circuit. 73, Don W3FPR On 11/15/2011 11:01 PM, Vic K2VCO wrote: What I did with my K2 was disconnect the ALC input line to the DB9 and use that for DTR, since even if I did operate SSB I would not use ALC!

Re: [Elecraft] How do you get N1MM to send CW to the K2?
It's not that bad! The ALC line coming from the DB9 connects to nothing until it gets to the control board. There is one trace to cut there, and then the four additional components can be placed against the board. You can connect to the key inputs right there. It is very neat, all on the control board. All you give up is the ALC input. You don't mess with any of the other lines. Yes, you need to use a cable with an additional wire. And yes, it might be bad if you don't cut the trace (or if you cut the wrong one!) I deliberately gave sketchy instructions, but if I can find the photos I took of the board, I'll write it up and put it on my website.

Re: [Elecraft] NR algorhythm
I had suggested that the VFO-A knob might be put to use while NR ADJ was selected. It could step through the NR settings in the following sequence: 1-1, 2-1, 3-1, etc. This would neatly complement the action of the VFO-B knob which has this sequence: 1-1, 1-2, 1-3, etc. As it is now the VFO-A knob has no function while NR ADJ is on. Also, I suppose the keypad might be used to enter two-digit NR settings directly while NR ADJ is on; random access, as it were. 73, Drew AF2Z On Tue, 15 Nov 2011 13:33:45 -0500 (EST), George wrote: I too would like to have a better way to adjust the NR settings.
