[Elecraft] Sharing a KX3 to multiple application on Mac OS 10.10
Any one know of a way to do it? I would like to be able to share the serial port among at least the KX3 utility and RUMLog (Which after reading the manual I have a much better understanding of) More software might come along later, but those are the big two for now. 72, Joshua Gould K8WXA EM89pn KX3# 7465 __ 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] Adjusting reference frequency some time after tx compensation
David I did almost the same, I did the extended temperature calibration with the XG50 and then afterwards did the REFCAL calibration on the 5th harmonic of my Z3801 10MHz GPSDO. This was last year and today I rechecked on the same 50MHz signal and found it was within a Hz of where it was before. Then I thought I will check it on 10MHz and it was about 40 Hz off. So setting up REFCAL at the highest frequency does not seem the best way as I had previously imagined it would be. I have now calibrated at 20 MHz which is giving almost the same point at 10 MHz and wee bit difference at 30 MHz. Now of course 50 MHz is 40 Hz out, but I am not that fussed as I don't see me using the KX3 for anything at that frequency as I have another 50MHz rig with more power. As a sanity check I tried another GPSDO and a 10 MHz OCXO and they all agreed. As to your second question, I believe that you do not need to repeat the extended temperature frequency cal if you recalibrate the REFCAL. Summary, I find the same discrepancy between calibrating at 50MHz and 20 or 10 MHz. I also find that the KX3 does keep its frequency calibration setting very well over a long period of time. 73 David Anderson GM4JJJ On 15 Feb 2015, at 21:51, David Orman orma...@corenode.com wrote: Hi, A while ago (months) I did the extended temperature compensation procedure using the XG50, which seemed successful. I decided to tune up to 20MHz recently, and noticed when in CW mode, if I ran spot (manual) I was off, by a small margin (33Hz). I'm assuming this is normal as time goes on, is this a correct assumption? Second question: assuming it is normal, and I should periodically re-calibrate using the XG50 or a known signal like WWV, is it safe to go to ref cal in the menu, unlock it, and manually tune/zero beat to adjust the frequency - without losing the calibration gained from doing the extended temperature compensation procedure? I'd rather not have to repeat that process any more than necessary, so I'm hoping the look-up table that generates is for something like offset based on temperature and so remains constant, and only the main reference calibration needs changing? I did this to test, and the menu item is still 'REF*CAL'. Tapping CMP while in this menu option, I have verified it is set to 'CUSTOM'.

Re: [Elecraft] K3 Beta 5r10 and LINK
The CPU between my ears is what the L vs R phase difference processes in Diversity mode. I can get a somewhat similar affect using AFX (or the equivalent with a Heil headset that has a phase reversal switch) but significantly without the benefit of the phase difference of the received signal from two different antennas in Diversity RX.

Re: [Elecraft] K3 Beta 5r10 and LINK
Note that the SUB switch doesn't even have a labeled hold function on the panel. You can chalk this up to our indecisiveness on what, exactly, it would be. But in a future run of K3 front panels it is likely to become DIV (diversity), eliminating the ambiguity. And I thought there's no hold function label beneath the SUB button because there is no space for it. ;-) 73, Olli - DH8BQA __ 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] Clock chip
I use the clock on the K3 as I no longer have a wristwatch and prefer not to have to pick up the iPhone to get the time. Those that don't need the clock can simply tap DISP and it will go away. I also use***MAIN: Alarm, Yes* on occasion to remind me of a net. *MAIN: Alarm* will also turn your rig ON at a preset time. New feature request: *MAIN: Alarm, Tap 4* to toggle a slightly audible dit every ten minutes as a reminder to ID. The clock on my K3 has been consistently slow since new, about 5 seconds per 24 hours. My preference is that it be a little more accurate, perhaps something closer to a quartz watch. Nothing too elaborate, not perfect, but more accurate than what we have now.

Re: [Elecraft] Kx3 RxIQ
Thanks Barry, that explanation helps alot. So I'm assuming that the IF output of the K3 is a very traditional IF as in other radios, ie it's not Quadrature, etc. Would that be correct? If so, another approach would be to feed into an A/D, and then do the rest in software, ie gnuradio. I wouldn't be surprised to find out that gnuradio already supports similar configurations, including down converting (for certain), splitting and creating the quadrature output (unknown). Sounds like a fun project. Wish I had time to pursue it!! ;) If I'm reading the block diagram correctly, it looks like an 8.125 MHz IF. -Chris On Mon, Feb 16, 2015 at 11:03 AM, Barry LaZar k3...@comcast.net wrote: Chris, If you are going after the K3 IF output, it is a single audio signal at the IF frequency. You will need to downconvert it to baseband and split it into two streams, one of which will need to be shifted by 90 degrees. It is these signals that go to a good sound card for playing. It will be the only way it will work. The P3 does everything it needs for spectrum display. The KX3 already gives baseband audio streams that are separated by 90 degrees meaning all you need to do is feed the streams to your sound card and operate on it with software. 73, Barry K3NDM On 2/16/2015 9:34 AM, Chris Hallinan wrote: I'm quite interested in experimenting in this area.

Re: [Elecraft] K3 Beta 5r10 and LINK
Here's an example where LINK was helpful to me: In the early AM I was calling CQ in CQWW160 and heard what I knew was someone just the very least bit above the noise level come back to me. I was using a HI-Z Triangular for Rx with the main and the sloper/INV-L Hybrid for the sub. I went to just the main and couldn't copy the signal and then went to LINK and with that I could barely make out JH0BBE. I could absolutely not do so otherwise at that moment. I just received his QSL for that Q in the mail and his is on the way back to him. The difference at that time between Main/Diversity/LINK was incredibly little but selecting through them at that time provided me with a new multiplier. There is I believe an attenuation when using Diversity which normally is insignificant but in rare marginal cases, hearing both signals without any attenuation can make the difference. To me, the use of Diversity is almost always an improvement to readability but not 100% of the time. I would never give up the use of my Sub Rx, it is magnificent and invaluable to me. Sometimes LINK is useful. Flame suit on. 73, Gary KA1J While reading this email thread, I just realized that many people don't know how to operate their K3s! Eliminating the LINK function should not cripple the diversity function, let alone eliminate it. I'm yet to read an example that would convince me about the usefulness of the function. In my opinion, the LINK function is a feature that I still don't understand why someone at Aptos bothered to program in the K3. As Don pointed out, the only use of this feature would be if a DX station was moving its TX frequency while working SPLIT. In more than 20 years as a ham chasing DX, I have never ever seen a DX station do that (it's kind of silly to do that because it would put in disadvantage the majority the DX'ers using other transceivers). Sorry for my bluntness 73,Robert-KP4Y On Monday, February 16, 2015 5:22 AM, Guy Olinger K2AV k2av@gmail.com wrote: Link uses both VFO's, with VFO A controlling main RX and VFO B controlling sub RX. Diversity uses only VFO A on *both* main RX and sub RX. Link memorizes the difference between VFO A and VFO B and maintains VFO B at that difference while VFO A is being tuned. If you do AB before link, it will still be two synthesizers that are not locked, just have the same current input parameters. In my case when I do this I rarely hear the band noise spreading out into the band noise sound stage needed for digging out weak discreet CW signals. Diversity is a phase lock between the two RX using the same set of frequency generating sources for both RX. This always produces the band noise sound stage. Note that the sound stage is not something generated in the K3. That is done in our minds by the same mechanism that allows us to pick out a single voice in a crowded noisy cafeteria. The band noise is spread out around the audio horizon or sound stage in my mind's ear. A discrete signal is in one place on the sound stage. My mind easily picks the discrete sound out of the spread-around noise. This is very much the same thing as listening to a stereo recording of an orchestra that begins with audience buzz, which is all over the audio horizon in my mind's ear. When the music begins I hear the violins to the left, though spread out a bit. I hear the tuba at a specific spot on the right. Once a K3 diversity RX operator has learned to use sound stage diversity, it is easily an S unit advantage on RX for a station at or in the noise that you can't see on the S meter. For me diversity is always on 160 through 40. Anything that craps diversity, for me throws away an S unit. If you are not getting the sound stage trying to use diversity, you really are not getting the benefit, and have some fun ahead of you when you do. 73, Guy K2AV On Sun, Feb 15, 2015 at 9:15 PM, Tom Blahovici tom...@videotron.ca wrote: Hi Joe, I guess there is some confusion then as to the function of Link.

Re: [Elecraft] Kx3 RxIQ
Chris, If you are going after the K3 IF output, it is a single audio signal at the IF frequency. You will need to downconvert it to baseband and split it into two streams, one of which will need to be shifted by 90 degrees. It is these signals that go to a good sound card for playing. It will be the only way it will work. The P3 does everything it needs for spectrum display. The KX3 already gives baseband audio streams that are separated by 90 degrees meaning all you need to do is feed the streams to your sound card and operate on it with software. 73, Barry K3NDM On 2/16/2015 9:34 AM, Chris Hallinan wrote: I'm quite interested in experimenting in this area.

Re: [Elecraft] K3 Beta 5r10 and LINK
LINK was added as the initial hold function of SUB because, at the time, we hadn't realized how important diversity mode would become to K3 users. We later added SUB as a long hold, which overloaded this switch (now three functions). This has been a continual source of complaints since we added the KRX3 option. Many users have trouble making the selection, because of the need to time the switch hold. Providing LINK as a menu entry, instead, has been on my list since the Pleistocene, and I finally got around to it. I tested this change on a large group of field testers (30+), and the response was overwhelmingly positive. That is why the change is now in the beta release (regular hold of SUB selecting DIVersity mode). Note that the SUB switch doesn't even have a labeled hold function on the panel. You can chalk this up to our indecisiveness on what, exactly, it would be. But in a future run of K3 front panels it is likely to become DIV (diversity), eliminating the ambiguity. 73, Wayne N6KR On Feb 15, 2015, at 11:40 PM, Vic Rosenthal k2vco@gmail.com wrote: I never, ever use LINK.

Re: [Elecraft] Adjusting reference frequency some time after tx compensation
David I did almost the same, I did the extended temperature calibration with the XG50 and then afterwards did the REFCAL calibration on the 5th harmonic of my Z3801 10MHz GPSDO. This was last year and today I rechecked on the same 50MHz signal and found it was within a Hz of where it was before. Then I thought I will check it on 10MHz and it was about 40 Hz off. So setting up REFCAL at the highest frequency does not seem the best way as I had previously imagined it would be. I have now calibrated at 20 MHz which is giving almost the same point at 10 MHz and wee bit difference at 30 MHz. Now of course 50 MHz is 40 Hz out, but I am not that fussed as I don't see me using the KX3 for anything at that frequency as I have another 50MHz rig with more power. As a sanity check I tried another GPSDO and a 10 MHz OCXO and they all agreed. As to your second question, I believe that you do not need to repeat the extended temperature frequency cal if you recalibrate the REFCAL. Summary, I find the same discrepancy between calibrating at 50MHz and 20 or 10 MHz. I also find that the KX3 does keep its frequency calibration setting very well over a long period of time. 73 David Anderson GM4JJJ On 15 Feb 2015, at 21:51, David Orman orma...@corenode.com wrote: Hi, A while ago (months) I did the extended temperature compensation procedure using the XG50, which seemed successful.

I'd rather not have to repeat that process any more than necessary, so I'm hoping the look-up table that generates is for something like offset based on temperature and so remains constant, and only the main reference calibration needs changing?

Re: [Elecraft] Sharing a KX3 to multiple application on Mac OS 10.10
Josh, I am not aware of a way to do it natively on OS X. However, I have OS X 10.10 and run VMWare Fusion. Under Fusion I am running Windows 8.1 and my KX3 is connected there. I use a serial port manager (free) called LP Bridge (LPB2). With LPB2 in place, I simultaneously run NaP3 (Pan Display Program, also free) and my Windows Logging program - LOG4OM. (yes, that’s free, too!) Not ideal, but I’ve had a K3/P3 for quite some time and when I got the KX3, I really missed the pan display. The PX3 was only dreamware when I got my KX3, so having NaP3 was super! I still use it, as my OS X is running on a 27” iMac and having the pan display of the KX3 on a screen that large is amazing! I have my K3 connected to the OS X side of things, where my main logging program (MacLoggerDX) runs. I export via ADIF from LOG4OM my KX3 contacts and haul them into MacLoggerDX periodically, via Dropbox.

Re: [Elecraft] K3: best roofing filter on RTTY
If you take the 250 Hz marketing name of the filter too seriously and set it to switch in at a DSP bandwidth of 250 Hz, then yes, it is perhaps too narrow for comfortable use with RTTY. On the other hand, if you set the filter to switch in at 350 Hz, the combination of the 250 Hz filter with a 350 Hz DSP bandwidth seems to work quite well for RTTY when QRM is heavy. When QRM is not quite so bad, you may get better decoding results using wider bandwidths in both the roofing filter and the DSP. 73, Rich VE3KI W0EB wrote: The narrowest filter I have in both receivers is the 400 Hz one.

Re: [Elecraft] K3 Beta 5r10 and LINK
My experience with LINK is all bad. If I'm in LINK I most likely don't know what is going on. It gets turned on in those gray hours in a contest when my really thinking brain has gone somewhere in the warm Caribbean to take a long nap. All left manning the rig is a brute beast that functions on rote. If the solution isn't already a habit, it probably can't think its way out of a paper bag. Getting caught with LINK one time had me listening to what my foggy brain concluded was an attempt to take over my run frequency. In fact it was the occupant of a frequency about 40 kHz away. I of course tried to operate through him to make him go away, including losing some number of weakies I couldn't copy with that racket going on. It took five or ten minutes to realize that all the racket was in my right ear and the offending run station was not on my S-meter. Then, to get me back to diversity, I had to turn SUB off, and do the long hold on SUB, which I didn't get right the first two times, probably for the same reason I wound up in LINK the first time. And in the piddling trying to get diversity back on, I didn't transmit enough and DID lose the run frequency for real. At least I didn't send the up 40 fellow a flame email after the contest like I did one time, when I didn't figure it out until the next day after I'd had some sleep. I don't want to take LINK away from anyone who likes or uses it, but removing the ghastly SUB-LINK-DIVERSITY sequence of old, with two kinds of HOLD, is a godsend. Thank you Wayne, Others seem to really diss diversity. And their commentary convinces me that some have not been doing sound-stage diversity correctly if at all. Sound-stage diversity DOES require at minimum a separate antenna on the sub RX, even if on 160 this is listening to your 80 inverted vee on the sub RX (not all that bad, the first thing I tried). Sound stage diversity does require phase-locking the two RX. Often listening diversity on two separately oriented RX antennas will seem to improve the performance of BOTH receive antennas. If one's idea of diversity includes the notion that going into diversity knocks down the main RX level, you really don't have it set up, and have a pleasant surprise awaiting discovery. 73, Guy K2AV On Mon, Feb 16, 2015 at 12:40 PM, Oliver Dröse dro...@necg.de wrote: Note that the SUB switch doesn't even have a labeled hold function on the panel.

I can get a somewhat similar affect using AFX (or the equivalent with a Heil headset that has a phase reversal switch) but significantly without the benefit of the phase difference of the received signal from two different antennas in Diversity RX. You (and Heil) are using the word phase incorrectly when you talk about reversing it. What that switch is doing is reversing the POLARITY. Polarity has two values -- normal and inverted. Polarity is the same for all frequencies. Bob Heil, who claims to be the audio guru should know better -- the word polarity has been used in this manner in pro audio for nearly 40 years. Phase is a continuously variable function measured in degrees (or radians), has the range of +/- infinity. Phase has no meaning for signals of different frequencies. When phase differences are the result of time differences between two signals of the same frequency (for example, a direct signal and a reflected one), the phase difference is proportional to the time difference. These multiple arrivals cause what we hear as picket fencing at VHF and UHF, and long slow fades on the lower frequency bands (including 160M). The peaks occur when direct and reflected are more nearly in phase, the dips occur when direct and reflected are nearly equal in amplitude but close to 180 degrees out of phase. Another example -- when we use lengths of feedline to provide phase shift for antenna arrays, the amount of phase shift depends on the frequency. If we want two antennas to be driven precisely in phase over a broad frequency range (for example, wide bands like 160M, 80M, and 10M), we should use two lines of equal length. A half-wave (or multiple of half-waves) will provide the desired phase relationship at a single design frequency, but a different value away from that frequency. 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 Beta 5r10 and LINK
To my simple minded (physics) view of things, polarity is to do with the direction in which the loudspeaker cone moves for a given direction of audio frequency current (Fleming's left hand rule etc.). So if two speakers have the same polarity then they will both move forwards or backwards at the same time, irrespective of the frequency (assuming they are being fed with the same signal of course!). Phase differences can only have any meaning for a given frequency and can have maximum values of +/- 180 deg, +/- pi rads etc. It is easy to see how the confusion can exist. Interestingly, an old pair of AR speakers I own have a 'polarity' switch. 73, Stephen G4SJP On 16 February 2015 at 19:47, Clive Lorton cl...@thelortons.co.uk wrote: On 16/02/2015 19:27, Jim Brown wrote: You (and Heil) are using the word phase incorrectly when you talk about reversing it.

Re: [Elecraft] Sharing a KX3 to multiple application on Mac OS 10.10
Sharing is a challenge, but not impossible. Consider if you require both applications to be able to control the unit. If this is the case, then I would say no. If you only want one to monitor the frequency of the radio but not provide input, then it is doable. The 'simple' way is to have a Y cable where one connection is the master connection that has full control of the radio and the other just listens to the radio communication. Steppir does this already as an example.' This Y cable would connect to the radio and would connect to 1 physical serial report as the master. Then, with another single wire it would go to another physical serial port in an RX only mode. The above is the safest so there are no port conflictions or control issues. In the windows world, there are tools to do this. In the Flex world we use DDUTIL or for others, PSTRotator does a good job of communicating with many devices. In the future, it would great if all the communications got off RS232 and moved to TCP or UDP and we can get away from RS232. These things take time of course. I hope that helps some.

I have the 681 35 key serial keypad, but in addition to using it alone I also use my logger/rig control through the same port using VSPE software. Works well.

I have the model 684 serial 24 key keypad. It is connected to my KX3 through a Y connection to the serial port on the KX3 (ACC1 if I recall correctly). After programming, it has no connection to the computer. I ran the programmer program and programmed the keypad on a WIN 7 OS computer and had no problems other than learning the macro commands and the KX3 variants. There are no data conflicts as the keypad only sends and the other serial device on ACC1 only listens. As an example, if I want to change from PSK31 on 14.070.000 USB at 1.0 watts (to drive my HR-50 at 25 wts) to SSB on 40 meters at 10 watts and set the filter to 2.5kHz I push one button.

He later published the project particulars in an article in QST I believe. He and several others were very helpful with macro issues and building the serial cable with the KX3 plug on one end.

Re: [Elecraft] Kx3 RxIQ
Chris, The IF out on the K3 is straight IF as it is going to be used in the radio. That is correct. It is not useable as it is for DSP purposes without a little work. The absolute simplest is to order a LP-Pan for the K3. It takes the IF out and gives you baseband IQ analog streams to be used for your purposes. Let me get a little technical. You must have a way to discern not only amplitude but phase information. By obtaining this information you can describe all of the signal information present in the streams. Doing a A/D on two streams of analog data that has a known phase shift between them allows for this. Quadrature is the easiest, IMHO, so that is why that is what is used. You could use the IF out and split it into two analog streams, shift one 90 degrees, and then do an A/D on them. However, getting a good A/D converters that operates at least 2X the K3's IF frequency is going to be expensive, and you probably want to over sample at 3-4 times the IF frequency. Going to baseband allows you to do it all with a $50-%100 sound card, simple minded economics and engineering. And it turns out that sound cards can do a superior job. The real trick in making a good SDR is making sure you don't overload the A/D converter and while making sure you receiver has enough sensitivity to not be internally limited by noise. Good sound cards have 24 bit A/D converters that should allow over 100 db dynamic range and most have pretty good internal noise figures. So, if you are really careful about gain distribution in the analog portions of your radio, you can end up with quite a radio. Elecraft is a prime example of this in both the K3 and the KX3. Hopefully, I have given you enough to think about to figure out what you want to do. Of course, there are number of ways to go, Ask a room full of engineers for an answer and I'd be shocked if you didn't get a room full of answers. The reason is that there are lots of compromises and which ones you make are how you view things. Very best of luck in where you want to go. 73, Barry K3NDM On 2/16/2015 12:49 PM, Chris Hallinan wrote: Thanks Barry, that explanation helps alot. So I'm assuming that the IF output of the K3 is a very traditional IF as in other radios, ie it's not Quadrature, etc. Would that be correct? If so, another approach would be to feed into an A/D, and then do the rest in software, ie gnuradio. I wouldn't be surprised to find out that gnuradio already supports similar configurations, including down converting (for certain), splitting and creating the quadrature output (unknown). Sounds like a fun project. Wish I had time to pursue it!! ;) If I'm reading the block diagram correctly, it looks like an 8.125 MHz IF. -Chris On Mon, Feb 16, 2015 at 11:03 AM, Barry LaZar k3...@comcast.net wrote: Chris, If you are going after the K3 IF output, it is a single audio signal at the IF frequency. You will need to downconvert it to baseband and split it into two streams, one of which will need to be shifted by 90 degrees. It is these signals that go to a good sound card for playing. It will be the only way it will work. The P3 does everything it needs for spectrum display.

I would like to expand on this post (below): RS-232 is a point to point protocol and the hardware requires normally one driver on each signal line and one receiver. In special circumstances, more than one receiver can be on any one signal line. BUT, never more than one driver. In other words, you cannot use a Y cable to connect a KX3 (or any other) to more than one regular COM port. SteppIR has been mentioned, but their controller only listens to the communications - there is a setting in the SteppIR controller which disconnects the drivers if you are using it that way. It is only under this special condition that a Y cable can be used. In this instance, the StepIR controller does not ever control the RS-232 signalling, it just listens to the traffic. 73, Don W3FPR On 2/16/2015 2:18 PM, Michael Walker wrote: Sharing is a challenge, but not impossible.

Re: [Elecraft] Kx3 RxIQ
K3 IF output is simply the 1st IF=8.215 MHz which is simple RF covering a wide bandwidth. Simple way to generate IQ baseband audio is with any of the inexpensive SDR's. I use the LP-Pan which was specifically designed for the K3 IF. the LP-Pan has a input bandwidth of about 400-KHz. I use either a emu-0202 which can support 192-KHz or a Delta44 which supports 90-KHz audio. Elecraft responded to customer desires and included IQ baseband output for the KX3, so one only needs a decent audio interface to a soundcard. You can make one yourself. Its on my lengthy to-do list. 73, Ed - KL7UW To: Barry LaZar k3...@comcast.net Cc: elecraft@mailman.qth.net elecraft@mailman.qth.net Subject: Re: [Elecraft] Kx3 RxIQ Message-ID: came0jbtbguxzumn3ojm2xxuiubmo3__jci84s_hgtcdokiv...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 Thanks Barry, that explanation helps alot. So I'm assuming that the IF output of the K3 is a very traditional IF as in other radios, ie it's not Quadrature, etc. Would that be correct? If so, another approach would be to feed into an A/D, and then do the rest in software, ie gnuradio. I wouldn't be surprised to find out that gnuradio already supports similar configurations, including down converting (for certain), splitting and creating the quadrature output (unknown). Sounds like a fun project. Wish I had time to pursue it!! ;) If I'm reading the block diagram correctly, it looks like an 8.125 MHz IF. -Chris 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] Clock chip
I think this might have been touched upon, but I wonder if a sw app might be possible that would update the K3 clock from your computer (say once per day)? Of course one can manually accomplish that using the K3 utility. For those of us whose K3 mainly stay in the shack and can be connected to a computer full-time that would be a nice feature that would probably solve this time issue with the clock. Maybe that feature could be added to a future version of the K3 editor? Of course time accuracy would be that of your computer (which there are many utilities which will maintain NIST accuracy - I use Dimension-4). 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] Bad Assumptions
The fun thing about ham radio is all of the different activities you can participate in. For me chasing DX has always been my main focus. I also work the occasional contest and in both of these activities the modern computer assisted operating station (Elecraft K-line, SDR-IQ, Dell I7 computer) is the way I choose to go. It is a challenge to integrate the software/firmware/hardware, and after retiring from 45 years working (Bank of America Computer Systems) and teaching (local Community Collage) computer technology, it keeps my very old brain working hard. (These daze I can't remember if I brushed my teeth this morning.) I am not big on digital, yet, but who knows when i will get a itch to expand that operating mode. On the other hand, for me at least, I don't get as much kick out of using this setup for ragchewing or participating in nets. That's where the operating position on the other side the shack comes in...Drake Paradise (well at least for me.) I pined after these Drake rigs when I could not afford them in the 70's and now they provide me with dials and meters and knobs, and opportunities to rebuild and upgrade them, pulling their cases off and soldering and wiring like I never really did before. And that makes me smile. The Drake Yahoo Group is just as accommodating as the Elecraft reflector, with wisdom and camaraderie. There is no computer on the Drake side of the shack, so operating and logging is totally old school, paper and pen. Of course the schematics and manuals are available on the Dell computer across the room, but a three-ring binder holds all the paper manuals and pertinent data for the rigs I have. I count myself as very lucky to be enjoying old and new ham radio in my retirement years. Modern radios will continue to improve and computers will continue to find their way into a modern shack. That is not stoppable. But any ham can draw his/her line anywhere when it comes to technology. Or if they are lucky enough they can have both ham worlds to operate in. PS. I don't even own a smart phone...I keep my flip phone on me in case I need to call 911 in a hurry! And it has a good enough camera to capture images of my dis-assembling a Drake rig so I can put it back together again. That's one of the lines I have drawn! 73 ..mike AI6II -- View this message in context: http://elecraft.365791.n2.nabble.com/Bad-Assumptions-tp7598656p7598672.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] RX SHFT=8.0 I.F. Image (16 kHz) Nulling
Ok, I reviewed the procedure -- it's been a long time since I did it. I think there is an error in the procedure. What you should do is tune the KX3 to the *same* frequency as your signal source. You should be in CW normal mode, RIT off, and you should verify that the signal source is giving a strong signal S9 to S9+30dB. If it is not in this range, you should set the preamp/attenuator settings to bring it in range. *Now* you tune the KX3 VFO up 16 kHz, and set the RIT to -1.1. The signal you now hear should be the image, which you should try to null out.

Re: [Elecraft] Who said anything about removing diversity? That would *never* happen...
I think he was talking about removing the feature that locks both VFOs together rather than diversity. The writer said that he did not think it was good to lock both VFOs together, but I think is is required for proper diversity operation to have both locked. I have not used diversity much because I do not have a good receive antenna for 160, but I would not want the VFO tracking feature to go away and I do not see how one could use diversity well without tracking VFOs.

Re: [Elecraft] Who said anything about removing diversity? That would *never* happen...
Willis, When in Diversity mode, the VFO that is controlling the frequency is VFO A only. There is no need to lock the VFOs in diversity - they are already 'locked' because only one VFO (and synthesizer) is being used. That assures that both the main and sub RX have the same frequency and phase relationship. I think this is the factor that has confused many. The locking (linking) of the VFOs have nothing to do with diversity mode. LINK is an altogether different animal. 73, Don W3FPR On 2/16/2015 7:54 PM, WILLIS COOKE via Elecraft wrote: I think he was talking about removing the feature that locks both VFOs together rather than diversity.

[Elecraft] Bad Assumptions
There seems to be an almost universal assumption that, if you have a transceiver in the shack, it is connected to a computer full-time. That is certainly not the case. Plenty --perhaps most-- of hams operate their rigs in a standalone mode without computer, even while at home. This may come as a shock to some of you. Exceptions to this rule include while updating firmware. This bad assumption usually rears its head when someone asks, What's the best way to operate split? or, How do you use the CW memories? and someone immediately responds, Well I push this here button in my favorite software and everything works great. I'm always frustrated and even a little annoyed by responses like this. A response like this is not answering exactly what was asked. Or at least, it assumes far too much. I recommend that, unless computer control is explicitly mentioned by the original poster, we shouldn't automatically offer a solution that requires a computer to work. Original posters should be more clear about whether a computer can be part of the solution.

Re: [Elecraft] RX SHFT=8.0 I.F. Image (16 kHz) Nulling
I've figured it out. Two part solution: 1) You don't hear any signal once you've tuned 16kHz off, the manual seems to indicate you should. You won't. I think this might be a carry-over from the first RX shift 8 section. You hear the tune once you engage the -1.1 RIT. 2) When using the PX3 as the signal source, the signal for 160m and 80m when trying to run the 16kHz procedure has the proper settings lost in noise. That's why APF was failing on them. I manually tuned ignoring APF and was able to null properly.

Re: [Elecraft] K3 Beta 5r10 and LINK
It seems that the term Polarity could be applicable to a single device, such as a loudspeaker, without reference to any other device. Connect the plus terminal of a 1.5v battery to the (+) terminal of a loudspeaker, and presumably the cone will move outward. Reversing the polarity of either the battery or the loudspeaker (but not both), will cause the cone will move in the opposite direction. But the Phase of a single device/measurement is kind of a meaningless concept without reference to another device/measurement. So perhaps the proper terminology is dependent upon context. At least that distinction works for my simple mind. 73, Dale WA8SRA On Mon, Feb 16, 2015 at 2:09 PM, Stephen Prior eastbrantw...@gmail.com wrote: ... polarity is to do with the direction in which the loudspeaker cone moves for a given direction of audio frequency current (Fleming's left hand rule etc.). So if two speakers have the same polarity then they will both move forwards or backwards at the same time... === I realize this discussion is kinda pointless and not worth prolonging, but nonetheless... it seems that if both speakers go in and out at the same time, the resulting sound waves would be in phase; whereas if one speaker goes out when the other goes in, the sound waves would be considered to be out of phase (i.e. the compressions and the rarefactions would cancel). So at least in the case of a pair of speakers sitting side-by-side and fed with the same audio, switching the so-called polarity of one would indeed change its phase relative to the other by 180 deg.

Re: [Elecraft] Clock chip
I use the clock on the K3. Mostly to keep time as I no longer have a wristwatch and prefer not to have to pick up the iPhone to get the time. Those that don't need the clock can simply tap DISP and it will go away. I also use***MAIN: Alarm, Yes* on occasion to remind me of a net. *MAIN: Alarm* will also turn your rig ON at a preset time. New feature request: *MAIN: Alarm, Tap 4* to toggle a slightly audible dit every ten minutes as a reminder to ID. The clock on my K3 has been consistently slow since new, about 5 seconds per 24 hours. My preference is that it be a little more accurate, perhaps something closer to a quartz watch.

I also bought WriteLog, and needed the computer connection. At least one computer has been in my shack ever since. Eventually I started using Commander, the control software that goes with DXKeeper to read the rig frequency and mode and put it in the log. Then, when LOTW and eQSL came along, it became very easy to upload my entire post-2003 logs.

Re: [Elecraft] OT Bad Assumptions
I too like to use my radio, not the computer, for casual and other non-frantic QSO's. :-) Based on the number of posts/questions about HRD and other radio control software, I think that might be a valid if not universal assumption. I think it's safe to say all contesters do, although I ran the Locust QSO Party QRP with my K2, a #2, and a piece of paper recently. It's likely that virtually all RTTY/Digital ops use a computer too [so far, I can recognize my call and TU on RTTY by ear, if I've been doing it for the last 3 hours and in the same exchange]. Al, I agree with you that, with the proliferation of external devices and software, an awful lot of the discussions here apply to getting a Signalink or MicroHam thingy working rather than to Elecraft equipment. K1's, K2's, K3's, and KX3's behave as they were designed. If you're going to add extra external stuff, you will have to deal with the makers of the external stuff, it's not Elecraft's fault. This list is a good resource for that and, at some juncture, it may be good to take it off-line to resolution. I have my laptop interfaced to my K3/P3/KAT500/KPA500. I use that interface and N1MM/MMTTY in contests ... well most of them. I chase SOTA activators a lot using a homebrew logger that will create .csv files to upload to the SOTA database, but which does not control or read anything from the K3. I confess, I have a Pigknob, external device, it solves some orthopedic issues for me. I added OT to the subject because it is. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 2/16/2015 5:10 PM, Al Lorona wrote: There seems to be an almost universal assumption that, if you have a transceiver in the shack, it is connected to a computer full-time.

Krebs voice here) I am in front of a computer all my working day I don't intend to let work invade my hobby. I drag a laptop into the shack to upgrade my K3's firmware every few years. I also use it to log my FD contacts. Other than that the computer is not allowed in the shack. I purchased my K3 because it sounded like a good idea after using my K2 for so many years. I could blame Lisa for my purchase but she is far too nice to be used as an excuse :) 73, Kevin.

The last time I'd contested was 20 years before, with paper logs and dupe sheets. :) A few weeks later, I was back on the air at home. I logged on paper for a week or two, but I soon learned about DXKeeper, and an older Thinkpad that I'd replaced in my small business found a permanent home in the shack. I also bought WriteLog, and needed the computer connection. At least one computer has been in my shack ever since. Eventually I started using Commander, the control software that goes with DXKeeper to read the rig frequency and mode and put it in the log. Then, when LOTW and eQSL came along, it became very easy to upload my entire post-2003 logs. Most hams who are not contesters have computers hooked up to their rigs when they want to operate digital modes, but they may or may not use a serial port for rig control. DXers often use CW Skimmer, which needs rig control. 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 Message delivered to vk1zzg...@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 mooo1...@yahoo.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 kev...@coho.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 Beta 5r10 and LINK
Johnny, I had the 7800 for a while, the reason it can't do diversity is that since the main and sub use different IF frequencies there is always a small (Sub 1Hz frequency different between the 2 receivers due to DDS rounding error differences between the main ad sub synths Neither link or diversity are 'going away' see the release notes * EASIER DIVERSITY RECEIVE SELECTION: A regular hold of SUB now goes directly into diversity receive, without first having to go through LINK. This should benefit most users of the KRX3 sub receiver, since few use the VFO linking function. Those who do use VFO linking can still turn it on by setting CONFIG:VFO LNK to ON. This menu entry can be assigned to a programmable function switch for easy selection if desired, eliminating the need to bring up the menu. Note: Remote-control command LN is another way to accomplish VFO linking. On Mon, 2015-02-16 at 00:51 +, Johnny Siu wrote: Hello Arie, I agree with you 'LINK' should not be abandoned.

Diversity puts the main RX audio on the left ear of the headset, and the Sub on the right ear. That's the normal situation.

Re: [Elecraft] K3 Beta 5r10 and LINK
While reading this email thread, I just realized that many people don't know how to operate their K3s! Eliminating the LINK function should not cripple the diversity function, let alone eliminate it. I'm yet to read an example that would convince me about the usefulness of the function. In my opinion, the LINK function is a feature that I still don't understand why someone at Aptos bothered to program in the K3. As Don pointed out, the only use of this feature would be if a DX station was moving its TX frequency while working SPLIT. In more than 20 years as a ham chasing DX, I have never ever seen a DX station do that (it's kind of silly to do that because it would put in disadvantage the majority the DX'ers using other transceivers). Sorry for my bluntness 73,Robert-KP4Y On Monday, February 16, 2015 5:22 AM, Guy Olinger K2AV k2av@gmail.com wrote: Link uses both VFO's, with VFO A controlling main RX and VFO B controlling sub RX. Diversity uses only VFO A on *both* main RX and sub RX. Link memorizes the difference between VFO A and VFO B and maintains VFO B at that difference while VFO A is being tuned. If you do AB before link, it will still be two synthesizers that are not locked, just have the same current input parameters. In my case when I do this I rarely hear the band noise spreading out into the band noise sound stage needed for digging out weak discreet CW signals. Diversity is a phase lock between the two RX using the same set of frequency generating sources for both RX. This always produces the band noise sound stage. Note that the sound stage is not something generated in the K3. That is done in our minds by the same mechanism that allows us to pick out a single voice in a crowded noisy cafeteria. The band noise is spread out around the audio horizon or sound stage in my mind's ear. A discrete signal is in one place on the sound stage. My mind easily picks the discrete sound out of the spread-around noise. This is very much the same thing as listening to a stereo recording of an orchestra that begins with audience buzz, which is all over the audio horizon in my mind's ear. When the music begins I hear the violins to the left, though spread out a bit. I hear the tuba at a specific spot on the right. Once a K3 diversity RX operator has learned to use sound stage diversity, it is easily an S unit advantage on RX for a station at or in the noise that you can't see on the S meter. For me diversity is always on 160 through 40. Anything that craps diversity, for me throws away an S unit. If you are not getting the sound stage trying to use diversity, you really are not getting the benefit, and have some fun ahead of you when you do. 73, Guy K2AV On Sun, Feb 15, 2015 at 9:15 PM, Tom Blahovici tom...@videotron.ca wrote: Hi Joe, I guess there is some confusion then as to the function of Link.

Re: [Elecraft] K3 Beta 5r10 and LINK
Vic, When the K3 is in diversity, it is in diversity, meaning that Main RX is on left ear and Sub Rx on right ear. This cannot be changed. Often, it is convenient to switch to only one antenna and one audio instead of two. So if a signal is really good on the Sub RX, I switch to B-B, meaning both ears hear the Sub RX audio. After finishing the QSO I switch back to A-B, the normal diversity audio and go on in diversity. This trick cannot be done if the K3 is in diversity. So I have the K3 in LINK-mode so that both VFO's stay toghether on the same frequencies. If the audio switching would be available when the K3 is in diversity mode, I would not need LINK. Now it is my way of working around this. 73 Arie PA3A Vic Rosenthal schreef op 16-2-2015 om 9:22: I don't understand. The K3 directly supports dual diversity reception. The beta makes it possible to enter diversity mode with a normal hold of the SUB button instead of the previously required long hold. The LINK function makes the two VFOs tune together, and they can be on the same frequency. But it isn't needed for diversity and would be clumsy to use for that purpose for several reasons (extra button pushes to equalize frequencies, bandwidth, etc.; possible need to change audio mixing setting). LINK is not the same as diversity, and I have never figured out what it is good for.

Re: [Elecraft] Diversity and Link
Do you think the link function is being removed altogether (it is not), or is the issue losing the use of HOLD on the SUB button for LINK? My interesting string of off-reflector emails about this mostly involves people using LINK in very complex ways, combined with other things. Oddly enough, if I understand them correctly, their use of LINK does not involve the use of the SUB button at all. I don't think any of them are hurt at all by the button change, apparently mostly annoyed that their usage of LINK is not recognized, that others seem to think that LINK has no use. I'm sure Wayne has figured that out. Given what I've gotten in email as a totally perimeter player on all this, Wayne must have been buried in email about it. I have learned a new term, button board, a device to go next to the keyboard somewhere, where the stuff done by the buttons is complicated, and, it seems, quite specific to the individual ham.

Re: [Elecraft] K3: best roofing filter on RTTY
The narrowest filter I have in both receivers is the 400 Hz one. I borrowed a K3 that had a 250 Hz filter in it once and tried it on RTTY. It works, but it's right on the margin of being too narrow. If someone is using one of the older Packet TNC's that have RTTY mode in them (they used 200 Hz shift instead of 170 and there are still a lot of them out there) it's really hard to get them tuned in with a 250 Hz filter, especially in weak signal/selective QSB situations. The 400 Hz filter doesn't seem to have that limitation though it does let slightly more noise in (easily handled with the DSP filters anyway.

Re: [Elecraft] Kx3 RxIQ
Hi Chris, Wirelessly (wlan) through the pignology piglet for rig control. The piglet establishes a hotspot to which the iPad will connect. I used the Apple camera adapter (lightning port version for iPad Air) coupled to a Griffin iMic. The camera adapter is poorly named as it really just offers a USB port to the iPad. The KX3 RX I/O plugs into the stereo input connector of the iMic; must use a USB sound card with stereo input as many USB sound cards do not have stereo mic inputs. Also, the USB sound cards (small USB drive like devices) seldom have wide bandwidth ( 44.1khz). Another reason the PX3 is so nice as it has 200 khz bandwidth. Note: iSDR will actually recognize the piglet and use it for rig control when the piglet is wirelessly connected to the iPad. So, Hamlog and iSDR both use the piglet; a nice bonus when more than one app will use the hardware. There are lots of youtube videos of Hams who have this set-up if you are interested to learn more from actual tutorial-like experiences. That is how I learned. Have a look at Jerry Taylor's channel (KD0BIK) on youtube and specifically the KX3 videos. They helped me a lot. There are also videos from other hams on iSDR, Griffin iMic, iPad, and the KX3. regards, Brian VE3IBW On Mon, Feb 16, 2015 at 9:34 AM, Chris Hallinan challi...@gmail.com wrote: Brian, how did you connect your KX3 to the iPad? -- Life is like Linux - it never stands still. __ 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

I haven't used one on my K3 but I do use one on my KX3. I have a Genovation model 684 serial programmable keypad that has 24 keys. One of those is used as a shift key so I have access to 46 macros at the touch of a button. Each macro space will hold approx. 180 characters so there is plenty of room for elaborate macros. Programming is a snap with the graphical interface supplied as is a cable. Cost was about $90.00 as I recall. There is a model with 35 keys. Might be the answer to your needs.

Plus, flip flopping back and forth between iSDR and Hamlog wasn't helping me be productive. You can never have too many screens :-) Now I use the PX3 as my panadapter instead of iSDR and can still use another computer to control the KX3 (PX3 has a pass through ACC1 jack). On the horizon...I am excited about the Raspberry Pi 2 (on back order) as this platform can support a number of Ham oriented programs I like to use (FLDigi, WSJT-X). Current draw for field work is about an amp-hour and I can use my iPad to VNC into the R-Pi.

Re: [Elecraft] K3 Beta 5r10 and LINK
Johnny, We have not abandoned the LINK function. It is available in the menu, and can be assigned to a programmable function switch. There's also an LN remote-control command that remains unchanged. It can be used from a computer or embedded in K3 front panel switch macros. But we decided to remove it from the SUB switch, because so many operators have accidentally gotten into LINK when the intent was to simply turn on the sub receiver or put it into diversity mode. This has resulted in many phone calls to customer support. Many K3 users have commented that they appreciate the removal of LINK from the SUB switch. 73, Wayne N6KR On Feb 15, 2015, at 4:51 PM, Johnny Siu vr2...@yahoo.com.hk wrote: Hello Arie, I agree with you 'LINK' should not be abandoned.

So both receivers keep working on the same freq. What I often use i diversity listening so with two receivers and two antennas on the samen freq. Diversity puts the main RX audio on the left ear of the headset, and the Sub on the right ear. That's the normal situation. In my case, the F9-F12 buttons in N1MM contain commands to the K3 that switch the audio to my liking (that can also be done in the Config, but that takes too much time during QSO) This way I can switch listening from diversity (listen both MainRX and SubRX at same time) to only main RX (main RX audio on both ears) or only sub RX (Sub RX audio on both ears) depending on where the signal is best. The commands to do this are in the programmers manual of the K3. It's really fun to control some beautiful K3 features from the keyboard like this. 73 Arie PA3A N2TK, Tony schreef op 15-2-2015 om 16:38: Hi Arie, I am not sure I understand what LINK does to help when both receivers are on the same freq.

That S9+60dB signal will have a weaker response in your receiver *if* your receiver was the limiting factor. If the transmitter phase noise (splatter and other 'bad stuff' was the original problem, then you may or may not have any improvement for that example. In other words, you will notice an improvement if other signals on the band are relatively clean. The improvement when other signals on the band are not clean will not be as obvious. Actually if an S9+60dB signal 10 kHz away is going to give you problems, then that signal is coming from a 'dirty transmitter'. I think a better example would be -- If you can operate within 2 kHz of a strong signal with the current KSYN3, then the KSYN3A may be able to allow you to operate within 1.5 to 1.8 kHz of that same signal. In other words, you will be able to saddle up closer to any signal unless the transmitter is creating trash. Note: All numbers are for relative comparison only. I pulled those numbers out of my head for illustration purposes only and do not represent any test data.
