[Elecraft] [KX3] running KX3 macros from PX3 function buttons
One of the limitations of the KX3 is that there are only two programable PF keys. The PX3 has more function keys available, and I'm wondering if anyone has thought of the possibility of firing off macros on the KX3 by pressing the function keys of the PX3. 73, Matt VK2RQ __ 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] Coiled Coax Choke
You say a 1:1 balun.What type is it and should it not be preventing common mode currents? If not Id consider one that will rather than adding a choke. I bought a commercial 1:1 Balun opened it up and found it to be just a length of RG8X looped once inside the casing with half a dozen ferrites around it. What I have done is have ground rods at the base of the pole. I am using a 10-80 +warc fan dipole that looks a little like a flattened spider web supported with guyed camouflage tent poles to about 40 ft I have 6 ferrites on the coax at the feed the ones I got out of the commercial balun. Then at the base I have several 5 ft copper pipes driven into the ground around the pole about 5 ft apart all bonded together with 6 gauge bare copper that is also burred a few inched below the surface safe from the lawn mower.

Re: [Elecraft] setting up Fldigi
...and I would like to add that downloading and installing Flrig will help quite a bit with controlling the radio. Flrig connects via XML to Fldigi and gives greater control than RigCAT or Hamlib. Flrig will give you CAT control of the K3 via serial port (or USB-to-serial). On another note, depending on your OS, there are two Yahoo groups pertaining to Fldigi - Win-Fldigi (I think) pertains to Fldigi on Windows; Linuxham pertains to Fldigi on Linux and the Mac OS.

Kit-build went smoothly, except for a brain fart on my part. This is a real cute little box, and will be even nicer when all the firmware is done. One very important thing missing is Fixed Tune Mode. 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] PX3
I noticed that in the FAQ, Jim. I sure hope it can be implemented since that's the only way I use my P3 and am holding off on the PX3 for that reason. I'm concerned that the FAQ has an if in it re this mode: If this feature is added at a future date, it may have somewhat different performance than in the P3, in terms of displayed bandwidth and allowed offset from the currently-tuned frequency. 73, Phil W7OX On 10/21/14, 6:33 PM, Jim Brown wrote: Kit-build went smoothly, except for a brain fart on my part.

[Elecraft] Coiled coax choke
Thanks to all who replied to my coiled-coax choke question. Good ideas, all; and I am off to study what K9YC has written on the subject . . . 73, Ted KN1CBR -- Message: 6 Date: Mon, 20 Oct 2014 19:48:29 -0700 From: Walter Underwood wun...@wunderwood.org To: elecraft@mailman.qth.net elecraft@mailman.qth.net Subject: Re: [Elecraft] Coiled Coax Choke Message-ID: b64c9b34-e2d9-489e-8b49-8962f7203...@wunderwood.org Content-Type: text/plain; charset=windows-1252 A choke in the middle of the transmission line could help, but the usual configuration is a current balun at the antenna to reject common-mode signals at the source, plus an optional choke at the entrance to the shack to reject noise picked up by the outside of the coax shield. A coiled-coax choke works OK, but you get the best rejection from a toroid-based choke or balun. I?ve had good results with the ones from Balun Designs (http://www.balundesigns.com). Putting a Balun Designs balun at my dipole dropped the noise by 6dB. I highly recommend K9YC?s super-detailed explanation of fighting noise in your antenna and elsewhere in your shack. http://audiosystemsgroup.com/RFI-Ham.pdf wunder K6WRU -- Message: 8 Date: Mon, 20 Oct 2014 20:31:35 -0700 From: Jim Brown j...@audiosystemsgroup.com To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Coiled Coax Choke Message-ID: 5445d397.9040...@audiosystemsgroup.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 10/20/2014 7:28 PM, Dauer, Edward wrote: I am thinking of adding a coiled coax common-mode choke to my system.

If not Id consider one that will rather than adding a choke. I bought a commercial 1:1 Balun opened it up and found it to be just a length of RG8X looped once inside the casing with half a dozen ferrites around it. What I have done is have ground rods at the base of the pole. I am using a 10-80 +warc fan dipole that looks a little like a flattened spider web supported with guyed camouflage tent poles to about 40 ft I have 6 ferrites on the coax at the feed the ones I got out of the commercial balun. Then at the base I have several 5 ft copper pipes driven into the ground around the pole about 5 ft apart all bonded together with 6 gauge bare copper that is also burred a few inched below the surface safe from the lawn mower. I have a barrel connector at the base that lets me connect the shield to this groundI have no common mode issues. at least I have not experienced any. __ 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] setting up Fldigi
I use it just fine it has said beta for a long time and I have not had issues. If using windows, to run multiple programs that control the K3 you can use a Virtual Serial Port Emulator VSPE. http://www.eterlogic.com/ it will let you run multiple programs that can control the K3 I run FLdigi with logger32 and both communicate at the same time just fine even K3 utility will run with it and K3-EZ all concurrently.32 bit version is free 64 bit you have to pay for since they have to pay some licence fee to Microsoft for components used in the 64bit version.

Thanks, Phil. I too use my P3s (three of them) ONLY in Fixed Tune Mode. It's next to useless if it is continually tracking the VFO frequency. If that function doesn't get added in a reasonable time, my PX3 will be for sale in a New York minute. :) 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 on 40 meters
Hi All, If there is a downside to the K3's size, the problem described in this thread demonstrates that. The rig is small, and so is the display. So, some of the displayed info gets overlooked easily. Still, there is a lot of info shown on the display, but much of it is in fine print! Which antenna you are using is one of those small print items. Or, maybe it's just that the info as to the antenna in use gets lost amid all the other info being displayed!!! Since my eyesight is slowly but surely going south on me, I tend to suffer from the small print issue--at least on occasion. In any event, I've committed the same sin as Fred did, and more than once. Most recently was when I was hearing about all sorts of activity on 6 meters, but I was hearing none. That went on for days until I realized I was listening on no antenna! Ask me how dumb I felt when I finally realized my error! I think Elecraft did a pretty good job arranging the K3's display of info, but surely it could have been a lot better. After all, nobody is perfect! Actually I strongly suspect that designing a proper display (regardless of how big or little it is) is more than just good organization. It's an art as well as a science! Probably there is some very esoteric psychological set of issues that would suggest that certain things be displayed a certain way, or with bigger font size, or whatever else you can do to make each piece of info stand out as necessary. Maybe if enough people are overlooking a key indicator on the display it could be enhanced by making it blink? I don't know what the solution really is. This may be a poor metaphor, but Fred's post made me think about all the times I went to a seminar, and the presenter had flip charts covered from corner to corner with all sorts of info listed in a very mundane way. In essence, the visual aids were so busy that not much of it sunk in. Compare that to someone who approaches making charts like this with a more modest amount of info on each page, or at least does a much better job of highlighting key info. Color coding helps, as does varying the size of key items. Underlining works too! Elecraft does employ a lot of techniques, but I can't say that they have done it as effectively as it could be. The point is that communication tools, such as displays, do present some significant opportunities to EFFECTIVELY convey various pieces of info. It probably takes a real expert to do it right. I don't know if we have any of those in the ham radio business! At least I can't think of a radio that had a display that struck me as being really efficient.
