Re: [Elecraft] KX3 Battery Life
Matt, Excellent hint.

Re: [Elecraft] K3: Any SSB user comments regarding the new synth?
Fred I bought a nifty up converter that converts everything from DC to 500 kHz up to 10 MHz and can listen to the low freqs on my K3 there. It is made by Jackson Harbor Press and has some mods made by Clifton Labs. There is a lot of info on the Clifton Labs website about using this kit. It was really cheap in comparison to even a single Synthesizer board and there is no sensitivity roll off. I think I paid $14 and had to add a diecast box enclosure and a DC feedthru connector with two BNC jacks. NAA is very strong as are a myriad of navigation beacons and a few low band broadcast stations from Europe and Africa. The big problem is man made noise from all sorts of consumer products. I use my 160 M beverages to receive. You could also make up or buy an active antenna and maybe get more isolation from man made noise. It would have to be matched as the normal input is low impedance. I think the low freq converter is a great amount of fun to play with. $14 is about what you pay for a good hamburger these days!!

Re: [Elecraft] K2 Filter settings
Gareth, Since you are using DM780, yes you can see the 100 Hz subcarrier. I usually use the Spectrogram 'scope display and that subcarrier is there but it is a low amplitude and becomes lost in low frequency 'trash' like any 60 Hz noise in the computer soundcard and the zero frequency spur. 73, Don W3FPR On 3/3/2015 2:29 AM, M5KVK - Gareth wrote: Thanks Don Since sending that email, I'd come across Wayne's article on the mechanics of CAL FIL. That opened my eyes to something I'd read, but clearly not absorbed: i.e. when a modified BFO is saved, the K2 re-calculates the value of VCO needed to obtain the same AF tone as before. Although the audio moves moves when the BFO is adjusted, once the BFO is saved, the tone goes back to where it was (or within 20Hz anyway). One thing though. Unless it's just my KSB2 filter, you can still see WWV's 100Hz sub-carrier on DM780 when the filter skirts are set as you suggest. It's very low, but DM780 has a high dynamic range and the carrier is just visible. Gareth, M5KVK Sent from my iPad On 3 Mar 2015, at 02:11, Don Wilhelm w3...@embarqmail.com wrote: Gareth, That is NOT correct. You must do things in order and all will work out properly. First, the 100 Hz WWV subcarrier should be outside the passband of the SSB filters, so it will have a very low amplitude. It is better to use the alternating 500 and 600 Hz as well as the 'on the minute' tone at 1000Hz to determine the correct tuning of WWV. The tone at 2 minutes after the hour is 440Hz. If your SSB OP1 (or FL1 if no KSB2) filter passbands are not properly aligned, do an initial alignment of the LSB and USB filters so the filter passband low frequency slope -5dB point is at 300 Hz (use Spectrogram to observe the passband position). Once the SSB FL1 filter is adjusted, then receive WWV and use the Spectrogram (or other audio spectrum analyzer) to properly tune the WWV transmitted tones. Once tuned properly, lock the VFO to prevent moving the VFO knob. With WWV properly tuned, set to CAL FCTR and alternate the internal counter probe between TP2 and TP1 while adjusting Control Board C22. Since all WWV transmissions are on '000.000 kHz boundaries, all you need to do is observe the 4 low order digits in the CAL FCTR display and you do not have to do the subtraction in every case. Once C22 is properly adjusted, put the counter probe in TP1 and run CAL PLL. When CAL PLL finishes, then go to CAL FIL. Even though the FL1 passband has been previously set, you must still change the BFO settings. Move them up one DAC count and back down to where they were before. Then adjust the BFOs for SSB FL2 thru FL4. I set the low frequency slope of FL2 at 350Hz, FL3 at 400Hz, and FL4 at 500Hz. Adjust the BFOs for the CW filters (and RTTY filters if you have them enabled) to properly position the filter passbands. If they were set correctly before, move them by one DAC step and back again - this is to force the BFO frequencies to be recorded into EEPROM with the current 4MHz reference frequency. After those steps, re-check the WWV tuning. It should be correct within 20 Hz. The BFO DAC steps are approximately 20 Hz wide, so you may see a shift in the tuning by that amount. If it is greater than 20 Hz, re-do the entire procedure from the beginning. I do this procedure more than 3 times a week on K2 repairs, and it always works. 73, Don W3FPR On 3/2/2015 11:11 AM, Gareth - M5KVK wrote: I realise this is close to becoming an obsession, but I really want to understand what's going on. Once I'd gone through my modified version of Wayne's process for adjusting the VCO (i.e. adjusting the VFO to have the WWV 100Hz sub-carrier on 100Hz), I realised that this applied only to LSB FIL1. As soon as I switched to FIL2, the sub-carrier moved and I needed to use CAL FIL to adjust it back. Also, if you want to move the position of the filter in the audio spectrum (e.g. to change where the skirts are), and thus change the BFO; you need to run Wayne's process again.

Re: [Elecraft] How can I get more Programmable Macros? (feature request?)
I don't know who first came up with this clever idea but here is the concept and an example: The concept is this: * Program a macro, say MACRO 7, and assign it to a function key, say PF2, to perform the first of sequence of commands. End the macro definition by assigning PF2 to the next macro command sequence, say MACRO 8. * Program MACRO 8 to do the second sequence of commands and end it by assigning PF2 to perform MACRO 7. Here is how it would work to use PF2 to enter the Split mode using the dual-watch receiver with the first hold, and then to exit Split mode with the second hold of PF2. * Using the Utility, assign MACRO 7 to: SWT25;SWT25;FT0;SB1;UP7;MN110;SWT33;SWH26;MN255; The first five enter dual-watch and QSY VFO A up 5. The other commands assign MACRO 8 to PF2: MN110; Enter the MACRO x menu (equivalent to holding MENU and rotating VFO B to MACRO x). SWT33; Tap the 8 switch. SWH26; Hold PF2. (This assigns PF2 to the commands in MACRO 8.) MN255; Exit menu mode. Now, * Assign MACRO 8 to: SWT25;SWT25;FT0;SB0;MN110;SWT32;SWH26;MN255; SWT32; Tap the 7 switch. SWH26; Hold PF2. (This assigns PF2 to the commands stored in MACRO 7.) Send the macros to the K3 using the K3 utility and then enter the MACRO 7 menu and hold PF2 to assign it to enter Split mode. The next PF2 hold will take us out of Split. Subsequent holds toggle back and forth. Neato, eh?

Re: [Elecraft] Synthesizer Issue
Wayne, This IS a big improvement for us Diversity users, particularly when using diversity to keep track of a pile of callers in a contest pileup. With the Old synths since the phase relationship between the 2 vfos would shift after TX the positioning of callers in the Image would alter after each transmit operation, with the new Synths this no longer happens. The already very good Diversity mode has gotten much better with this upgrade. I'd also suggest that folks who didn't take to diversity before might wish to give it a second try. For Diversity reception the RX antenna needs to be different than the TX antenna (E.g a vertical and a beam, or a doublet ) you don't need a dedicated RX antenna, it just needs to have different characteristics than the main antenna. Physical separation /or polarity differences will also help. For me, the price of the upgrade was worth it for the Diversity improvements alone 73 Brendan EI6IZ On Mon, 2015-03-02 at 18:21 -0800, Wayne Burdick wrote: Some users of the new synthesizer have also reported an improvement in the way diversity mode sounds. This is due to a change in the way the receivers are driven by the synths. In diversity mode, as long as the main and sub crystal filter offsets are matched, both receivers are driven by the main synth (the sub synth is not used in this case). So, when the VFO is moved, the local oscillator phase relationship remains stable between the main and sub receivers. With the original synths, moving the VFO even a small amount causes both the main and sub synths to be updated. Since they use separate LC oscillators, the phase relationship will change. The two will remain phase-locked to the reference, but the absolute value of the phase between the two synths will be some value between 0 and 180 degrees. We'll add this to the FAQ. 73, Wayne N6KR On Mar 2, 2015, at 6:10 PM, Walter Underwood wun...@wunderwood.org wrote: Start with the FAQ here: http://www.elecraft.com/manual/KSYN3A%20FAQ-ver-C-2.pdf The original announcement on this list described it like this: The KSYN3A synthesizer module is a completely new design that improves on the original KSYN3 in several ways: ULTRA-LOW PHASE NOISE The KSYN3A significantly improves the K3's already excellent RX and TX phase noise at close carrier spacings.

(feature request?) I don't know who first came up with this clever idea but here is the concept and an example: The concept is this: * Program a macro, say MACRO 7, and assign it to a function key, say PF2, to perform the first of sequence of commands. End the macro definition by assigning PF2 to the next macro command sequence, say MACRO 8. * Program MACRO 8 to do the second sequence of commands and end it by assigning PF2 to perform MACRO 7. Here is how it would work to use PF2 to enter the Split mode using the dual-watch receiver with the first hold, and then to exit Split mode with the second hold of PF2. * Using the Utility, assign MACRO 7 to: SWT25;SWT25;FT0;SB1;UP7;MN110;SWT33;SWH26;MN255; The first five enter dual-watch and QSY VFO A up 5. The other commands assign MACRO 8 to PF2: MN110; Enter the MACRO x menu (equivalent to holding MENU and rotating VFO B to MACRO x). SWT33; Tap the 8 switch. SWH26; Hold PF2. (This assigns PF2 to the commands in MACRO 8.) MN255; Exit menu mode. Now, * Assign MACRO 8 to: SWT25;SWT25;FT0;SB0;MN110;SWT32;SWH26;MN255; SWT32; Tap the 7 switch. SWH26; Hold PF2. (This assigns PF2 to the commands stored in MACRO 7.) Send the macros to the K3 using the K3 utility and then enter the MACRO 7 menu and hold PF2 to assign it to enter Split mode. The next PF2 hold will take us out of Split. Subsequent holds toggle back and forth. Neato, eh?

(feature request?) Wayne, *Q1*: Did you just say that macros can be self-modifying! I haven't found the Write commands to do that yet. Can you or any other really smart guys elaborate? For example, Let's say I'd like to create a toggle with a single macro. I would like it to do this without having an external application controlling things. So, internal to the K3, a macro would perform one or more functions, then before exiting, would rewrite itself to unset what was just done. Using the sample macro from Table 2 in the Programmers Reference for AMP ON and let's just assign it to say, Macro 1 In pseudo-code, I'd like it to run: MN019;MP001;MN255;PC065;DB65;DB77;DB80;DB32;DB79;DB78 and then, before the macro finishes, I would like it to rewrite itself to: MN019;MP000;MN255;PC100;DB65;DB77;DB80;DB32;DB79;DB70;DB70 Each time Macro 1 is executed, it toggles the Logic 1 output and alters the power output and displays AMP ON (or AMP OFF). One button thus becomes a toggle. Press a button, the external amp is enabled, and the drive is lowered for it. Press it again, and the amp is disabled and drive is raised back. Seems like all I need is a macro command that allows a new macro string to be written, especially to the one running at the time :) You could also have one macro change other macros in this way. In effect, you would only be limited by your imagination and what you can get stored in 120 character pieces. Hopefully we aren't limited in how many FLASH Write operations can be performed to the EEPROM. (1 million or more maybe? ) Since the K3 Utility obviously has the ability to write to the macro storage locations, would it be possible for macros to eat their own dog food too? If the macro language supports basic branching, I guess it could be done inline to the macro and not have to rewrite itself so... *Q2*: Is there a way to do IIF (or IF/ELSE) branching in a single macro? (strictly a wishlist item) In other words: IF (value) THEN (macro string) ELSE (another macro string) All this comes from my experience in making SCOM 7K controllers self modify it's macros to make wonderful things happen.

Re: [Elecraft] How can I get more Programmable Macros? (feature request?)
Seeing the request for self modifying macros, I thought I'd re-post these how-to documents that I posted on this reflector a number of years ago. Hopefully they will help you understand how to create your own macros which can be used to rotate between a series of parameter changes via a single PF1 or PF2 key press. Have fun playing with them, without as many headaches that I had in learning how to get them to work. 73, Rich - K1HTV For those of you who want to play more with macros, here are four that I use to set up my K3 for USB, CW, DATA-A and RTTY. Parameters that are set up include mode, receiver bandwidth, audio input connector (Front Panel for microphone, rear Line-In jack for DATA-A modes), Mic Gain and Compression level for SSB, CW Speed, VFO lock for DATA-A modes like PSK31, JT65 and WSPR. You can add or change other parameters in the macros for the various modes as you see fit. Macros are created using the K3 Utility program on a computer connected to the K3 via one of its COM ports. 16 Macros can be save in the K3 Utility but only the first 8 macros can be uploaded to the K3. The macros can be tested using the K3 Utlity in real time. Once they have been uploaded to the eight K3 internal macro memory locations, they can be assigned to various keys. Each can be assigned to any of the M1-4 (Tap) keys, or M1-4 (Hold), or the PF1 or PF2 (Hold) keys. ***NOTE*** In the case below, 7 macros are created using the K3 Utility program. The first 4 macros (associated with 4 different modes) are loaded into MACRO memory positions 1,2,3 4 and programmed into the PF1 key. The last 3 macros (associated with setting 3 different power levels) are loaded into MACRO memory positions 5, 6 7. After they are loaded, when you HOLD the PF1 key the K3 will toggle between the USB, CW, DATA-A and RTTY modes. The 7 character mnemonic assigned to that mode wil flash briefly on the LCD screen. Wait for it to flash before HOLDing the PF1 button to toggle to the next mode. In a similar manner, when you HOLD the PF2 key, the power K3 level will switch to one of three different power settings.

Re: [Elecraft] Why Upgrade (Was: Re: New K3 Syn)
Dave: I believe we're pretty much in agreement on this... On Mar 3, 2015, at 1:51 AM, David Gilbert xda...@cis-broadband.com wrote: You need to research the concept of the time value of money. As I said before, if the benefit is useful to you now, by all means buy the upgrade now. If it isn't, it simply becomes a race between inflation and potential increases in cost whether or not it makes any sense to do so. Inflation and potential cost increases are indeed components of time value of money as well as what is the expected value of the radio in the future? I did not use that phrase, but the concept of time value of money includes expected inflation/cost increases as well as the projected price for an item. I also made the initial presumption that the widget would be purchased in any event in the next couple of years and installed in the radio; I wasn't suggesting that the decision to purchase in of itself is the proper one to make. Please keep in mind that Time Value of Money basically states that a dollar today is worth more than a dollar tomorrow. The longer the horizon, the less valuable future money is worth in today's environment; that is why future earnings are discounted when estimating the value of the same dollar amount after taking into account any potential future income stream from interest or other revenue generator using those same funds. In today's world where current interest rates are almost non-existent and there is the potential for future price increases, and assuming that the purchase decision has been definitely made (I'm going to buy this either today or next year) the time value of money concept suggests that if you have the funds, buy it now rather than later because of the likelihood that your dollar will buy you less in the future than today. Everything else you said is simply a rationalization. EXACTLY! Everyone implicitly or explicitly makes purchasing decisions based upon a variety of factors and considerations and we all attempt to organize (rationalize) potentially disparate information in a way that makes sense to us. These may include: 1. Emotion. I gotta have one of those! or The joy that I get from this is worth the price. 2. Utility. The benefit in terms of how I use my radio will be enhanced by this widget by x%. 3. Cost/Benefit Analysis. The cost of the widget is less than the perceived value of using this widget. 4. Future Value. My equipment will be worth more to someone else if this widget is included. 5. Future Return. When I sell my radio, the incremental revenue gained by including the widget will be greater than the cost of the widget or When I sell my radio, the incremental revenue by including the widget PLUS the value of the benefit of using the widget while I owned it is greater than the cost of the widget. 6. Liquidity. Can I afford to buy it now given other purchasing needs that may have a higher priority? 7. Alternative Choices. I have only $xxx to spend on my amateur radio hobby. Is this the best way to use my dollars, or are there other products that will fill more important needs than this one? This last consideration notes the need to prioritize purchasing decisions. One definition of economics is roughly how allocation of scarce resources is done in a world of unlimited wants. Our pocketbooks are not deep enough to cover all wants; everyone has to prioritize which wants are met based upon their own criteria. Against these rationalizations is whether future reality meets our expectations. Since no one can predict the future, we all make financial estimations based upon past experience, observing current conditions, making assumptions about the future, and perhaps hope. We're always taking bets that our ability to predict future outcomes will produce a better result than a different decision. So everyone will come to their own conclusions and there is no universal right answer. My response below was simply meant to highlight one possible approach to the question you originally asked (Please explain the advantage of spending all that money now instead of potentially spending it several years from now when you might ... might ... want to sell the rig), taking into account both the cost of money as well as how we might view depreciation and relative value of a widget to the purchaser today and the future buyer in a couple of years. I also noted that selling a rig has its own considerations and that Elecraft's process of product improvement may well allow the current owner to benefit from those enhancements and not sell the rig in order to gain the latest benefits in a different product. In other words, generally speaking it is usually better to pay for incremental improvements in a rig that is already paid for than to sell it used (at a discount) and purchas e a replacement (new at full retail price) unless the new technology is such a game changer

Re: [Elecraft] K3: Any SSB user comments regarding the new synth?
Dave, I guess if you only want to receive that is a good choice. The new SYNTH enables both Tx and Rx at below 490-KHz (current synth will work down to 490). For those interested in operating on 472-478 MHz the K3+(new)SYNTH makes this possible (with the addition of an experimental license from the FCC). I will get the new synth when I have the funds (cost is x2 as I have the KRX3). Early on air reports look good for general use and extension to the new 630 meter band is a real plus! 73, Ed - KL7UW Re: TEST mode - I stand corrected by Eric (NO3M).

It is made by Jackson Harbor Press and has some mods made by Clifton Labs. There is a lot of info on the Clifton Labs website about using this kit. It was really cheap in comparison to even a single Synthesizer board and there is no sensitivity roll off. I think I paid $14 and had to add a diecast box enclosure and a DC feedthru connector with two BNC jacks. NAA is very strong as are a myriad of navigation beacons and a few low band broadcast stations from Europe and Africa. The big problem is man made noise from all sorts of consumer products. I use my 160 M beverages to receive. You could also make up or buy an active antenna and maybe get more isolation from man made noise. It would have to be matched as the normal input is low impedance. I think the low freq converter is a great amount of fun to play with. $14 is about what you pay for a good hamburger these days!!

Re: [Elecraft] Synthesizer Issue
Wayne, For folks that were using the two receivers for VHF EME polarity diversity reception over a wide bandwidth with MAP65 software, where they would have gain and phase matched preamps this must be an improvement for them. I think it was not generally understood that the absolute value of the phase relationship of the receivers would change as the VFO was moved. The only person I know that is currently using his K3 for doing this is Ed KL7UW, so he may be interested in this. 73 David Anderson GM4JJJ On 3 Mar 2015, at 02:21, Wayne Burdick n...@elecraft.com wrote: Some users of the new synthesizer have also reported an improvement in the way diversity mode sounds. This is due to a change in the way the receivers are driven by the synths. In diversity mode, as long as the main and sub crystal filter offsets are matched, both receivers are driven by the main synth (the sub synth is not used in this case). So, when the VFO is moved, the local oscillator phase relationship remains stable between the main and sub receivers. With the original synths, moving the VFO even a small amount causes both the main and sub synths to be updated. Since they use separate LC oscillators, the phase relationship will change. The two will remain phase-locked to the reference, but the absolute value of the phase between the two synths will be some value between 0 and 180 degrees. We'll add this to the FAQ. 73, Wayne N6KR On Mar 2, 2015, at 6:10 PM, Walter Underwood wun...@wunderwood.org wrote: Start with the FAQ here: http://www.elecraft.com/manual/KSYN3A%20FAQ-ver-C-2.pdf The original announcement on this list described it like this: The KSYN3A synthesizer module is a completely new design that improves on the original KSYN3 in several ways: ULTRA-LOW PHASE NOISE The KSYN3A significantly improves the K3's already excellent RX and TX phase noise at close carrier spacings. This in turn noticeably improves the K3's top performing close spaced Rx dynamic range, yielding even better weak signal detection in the presence of strong signals.

This K3 has all options except 2M module. Have not restored my saved configuration file. 3) Done a transmit gain calibration, can send the results if you think I should. 4) Observed the following with the K3 in CW mode and the power output set to 100W: When I key the K3 (for a short time, say less than 5 seconds) on a band (say 10M) with a continuous key down, the SWR and RF output bar graphs will go blank after briefly showing normally. The power output at that time as measured on the W2 will be low, around 70 watts or so (varies with each band). When I again key the K3, I generally (not always) get the same result. After two, maybe three more keyings, the power output slowly rises. After another one or two keyings the output will be at 100 or more and the bar graphs will persist. After another keying, the power output stays as it was the previous time, but the bar graphs once again go blank. 5) When I change to another band, all this happens again, pretty much in the same order. After coming back to a band where this behavior has been previously noted, it happens again from the start. 6) I have never noticed this behavior before installing the new synthesizers, but I never used the K3 barefoot at 100W either (always used the KPA500). 7) There does seems to be a spike issue on 10M that initially faults the KPA500, but can be mitigated by reducing the K3 output power but that results in low drive to the KPA500 so that its output is in the 400 watt range. If you want, I can revert to the old synthesizers if you think it would be worth while to do so, but I would only install the main unit and disable the sub receiver by not installing its synthesizer. I don’t know if this is a hardware or software issue, but the blanking of the graphs seems odd for a hardware problem.

I/Q is a natural fallout of the complex Fourier transform, but that does not make it intuitive. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) On Mar 3, 2015, at 4:18 PM, Al Lorona alor...@sbcglobal.net wrote: Hi, Richard, These are very good questions.

Re: [Elecraft] I/Q
Richard, The I and Q signals contain baseband (audio frequency range) signals which vary in both frequency and amplitude. The magic is that the I and Q channels are 90 degrees out of phase with each other. Each channel is what could be referred to as a normal audio signal. The 90 degree fixed relationship between the 2 signals no matter what the frequency or amplitude does the deed - each channel carries the same information, but the phase relationship 'does the magic'. With the 90 degrees out of phase information one can create (or decode) any form of modulation wanted - I did that way back when in my EE classes using pure math - it is a bunch of sines and cosines with a lot of other things thrown it. When you think of it that way, remember that the sine and cosine functions are 90 degrees apart. My studies were back in the pure analog days and the math was a bear, but today with ADCs available, those signals can be digitized and the math manipulated by a computer before sending the result to a digital to analog converter (DAC). A full understanding may require in-depth study into modulation forms and techniques as well as skills in manipulating math equations involving sines and cosines. De-modulation is similar, but the opposite of modulation. Sometimes it is helpful to keep the pure math relationships in mind to fully understand what is going on. For a simplified view, a spectum display can be created by using Fast Fourier Transforms (FFT) and also by other techniques which will transform from the time domain to the frequency domain. That is what is being done to present the display on the PX3. In the time domain, you see a signal like you would observe on an oscilloscope - amplitude vs. time. In the frequency domain, you see the amplitude vs. frequency at any one instance of time. The 90 degree out of phase signals are necessary to convert from the time domain to the frequency domain (or vice-versa). If you want to dig into the math behind modulation techniques, then be my guest. The nice thing about DSP is that the math can be done perfectly within the range of the resolution of the ADC and DAC devices used. How good the DSP is depends on how faithfully it can represent the analog signal, and that depends on the number of bits of resolution that are needed for the task at hand. Hopefully this information is helpful. You are asking a complex question, and several others have given you guides to more detailed info. You can either accept my simplified answer, or dig into it deeper and come out with the full details. 73, Don W3FPR On 3/3/2015 4:59 PM, Rstafford12 wrote: I am having trouble with I/Q modulation. 1) Do the I and Q components have a frequency, or are they just amplitudes.

Re: [Elecraft] I/Q
not going to repeat what everyone has already posted: One begins with an RF signal which has modulation (easiest to consider the modulation SSB and even easier if you take the example of a two-tone test signal for SSB). The first step in producing IQ output is to spit the RF into two parallel mixers that use the same frequency LO, but one is shifted 90-degrees in phase. The LO is the same frequency as the RF so one gets audio as an output (same thing one does in an SSB demodulator). The two resulting audio outputs are 90-degree out of phase with each other. In the typical SDR the next step it convert to digital using a analog to digital converter (ADC)(hams are using their soundcard as a ADC). The resulting two digital signals are out of phase with each other and can be processed by a computer (called an DSP = digital signal processor). Due to the unique mathematical properties of the two digital signals one can recover CW/DSB/SSB/AM/FM/PSK modulation types (and I may have left out others). This is a very rudimentary (non-mathematical) description. The true beauty of using IQ is its versatility. No longer does the receiver have to have a product detector, discriminator, envelope detector, etc. The DSP does it all in digital form and re-converts the demodulated signal back to audio (or displays the signal on a screen). http://www.kl7uw.com/MAP65.htm the diagram may help understanding. 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Synthesizer Issue
Dave, Wayne, others: Improved synthesizer phase noise will improve eme similarly to any weak-signal reception in presence of strong adjacent frequency interference. Dual polarity diversity reception for eme requires software to recover the polarity information. Two programs that I am aware of do this: SM5BSZ's Linrad (Leif Asbrink) and MAP65 (Joe Tayor). The software require two phase-locked receivers tuned to the same frequency to produce two IQ outputs which are in-phase with each other. Then the amplitude difference will produce polarity information which can be displayed and the software can digitally maximize SNR for best sensitivity (digitally aligns the output to the polarity of the signal). This does require both preamps, downconverters, receivers, and SDR's to have a constant phase relationship. Both sw have calibration routines to compensate the fixed phase difference in signal paths. Gains need to be balanced, as well. This is virtually impossible to achieve perfectly so the sw designers added a utiltity to test the difference and add digital compensation to remove this. My preamps are within less than a dB difference in gain and the downconverter uses an identical ckt as does the K3/KRX3. I use two LP-Pan for the SDR running on the 1st IF's of the K3/KRX3 with them using a common LO. Finding a test signal to perform the calibration is the hard part. Some eme signals are close to 45-degree polarity that is needed for this procedure. I will eventually upgrade my K3 with the new synth boards. 73, Ed - KL7UW Date: Tue, 3 Mar 2015 22:21:13 + From: David Anderson gm4...@yahoo.co.uk To: Wayne Burdick n...@elecraft.com Cc: elecraft elecraft@mailman.qth.net Subject: Re: [Elecraft] Synthesizer Issue Message-ID: e456211e-dc8b-4ea5-9fb2-c5c4debf0...@yahoo.co.uk Content-Type: text/plain; charset=utf-8 Wayne, For folks that were using the two receivers for VHF EME polarity diversity reception over a wide bandwidth with MAP65 software, where they would have gain and phase matched preamps this must be an improvement for them.

This is due to a change in the way the receivers are driven by the synths. In diversity mode, as long as the main and sub crystal filter offsets are matched, both receivers are driven by the main synth (the sub synth is not used in this case). So, when the VFO is moved, the local oscillator phase relationship remains stable between the main and sub receivers. With the original synths, moving the VFO even a small amount causes both the main and sub synths to be updated. Since they use separate LC oscillators, the phase relationship will change. The two will remain phase-locked to the reference, but the absolute value of the phase between the two synths will be some value between 0 and 180 degrees.

[Elecraft] My K3 SYN boards finally arrived
Christmas has arrived at my QTH. I just popped in the new SYN boards and have played around with my K3 for a few hours. I could almost cry because this was the one thing I was looking for that the K3 was slightly deficient in.good smooth CW above 36-38 WPM with RIT or SPLIT on. I am thrilled to hear how nice it now sends CW without being jumpy. I'm not a real QRQ guy but when I'm in a contest down in the Caribbean I need to CQ at ~42 wpm and the K3 just wasn't able to handle it previously. It now sounds as smooth as butter. I've also never before been a QSK guy (even though my delay is usually set at only 12ms) but the huge improvement in QSK is an added benefit and may make a QSK guy out of me yet. I even tried QSK using SPLIT/SUB just now and it was perfect. If the RX dynamics are anywhere near the improvement I've seen so far I'll have hit the lottery. I only have a wire in the attic here at the house so I can't really test the benefits of the better RX specs until I get the boards installed on my contest K3s (out in the country with good antennas) but even if nothing else changes, I'm just thrilled with this new upgrade.

Re: [Elecraft] [Bulk] A way to show both SPLIT and NON-SPLIT warnings
On Feb 18, 2015, at 11:03 AM, Wayne Burdick n...@elecraft.com wrote: Joe, Just because there are three indicators for SPLIT already doesn't mean that the problem has been solved. Even crack operators have admitted during the past few days that they occasionally forget their split state, with embarrassing consequences. This is proof that the indications can and should be improved, if possible. See my previous posting. OK, I’ll tell you what often messes me up. One of the aggravating things about the K3 is that you cannot move freely between modes if split is engaged. You can change from CW to SSB or vice versa, but if you are in Data mode, or if you are trying to switch to Data mode, it won’t go until you turn off split. I generally tune in a station with VFO A, then hit AB (twice) and move B to the correct DX receive frequency. If split is on, everything is good. If, for some reason, I had split on, but then turned it off so I could change modes, I sometimes forget to turn it back on. I hate this. I wish I could just select whatever mode in VFO A I want, regardless of split — the firmware should prevent me from transmitting in unsupported configurations, of course, with an appropriate message in the VFO B display. If this could be fixed, it would help prevent me from making this mistake. (Yeah, I know, can I not see the bright yellow delta-F light? You’d think so….)

Re: [Elecraft] CW listening pitch
Like W4BQF, I can carry on a QSO at 100+ WPM. Personally, I like the tone bout 500 Hz. Don't forget that a square wave is made up of a sine wave + its odd harmonics. The higher the fundamental freq, the higher those first few, and most important, odd harmonics are. This can cause the waveform to lose its sharp edges and sound mushy when there is attenuation of those higher freqs due to hearing loss. Re musical ability, I played clarinet in jr high school and early high school, but gave it up because they required performing in marching band at the weekend football games - this interfered with contesting!

I'm primarily a CW op, but lately I have been playing with RTTY and PSK. One thing that I've noticed is that I don't seem to be able to activate VOX when in Data Mode on 20 meters. This works fine on every band, but on 20 meters it displays an N/A when I try to activate it. I'm sure there is something obvious that I'm missing here. Anyone have any ideas?
