Re: [Elecraft] KAT500 antenna selection
630m is a 7-KHz wide band. Probably not requiring an auto-tuner. Most on 630m will be running a very short antenna in terms of wavelength which usually incorporates a large loading coil in series. My 630m antenna is an Inverted-L 43 by 122 feet and I have a base coil to ground which tunes out reactance with a movable tap. Matching to 50-ohms is done a couple turns up from the cold end. 2:1 SWR is 5-KHz wide. Efficiency is 4%. Radiation resistance is 0.8 ohms. EIRP = 4.15w. My K3 drives a 100w surplus NDB transmitter at 0.1 mw. I QRV on 600m in 2012 as WD2XSH/45 (experimental license) 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: 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

[Elecraft] Elecraft CW Net Announcement
Good Evening, March has come in like a soggy walrus. The snow is coming down in long slushy streaks like a less lethal version of threads raining down on Pern. Nonetheless if you get hit by one you're soaked. It is a good time to stay inside by a warm fire reading. Currently "Space Vikings" by H. Beam Piper There is a real, if tiny, sunspot breaking the month long streak of spotless days. Solar activity is low so I expect slow QSB with steady noise on 20 and faster QSB on 40 meters. The sun angle is changing rapidly so 40 meters may reach even farther than it did last week. We shall see.

Re: [Elecraft] KAT500 antenna selection
I'll submit that the KAT500 was designed long before 630 meters was generally open and the values needed to present a low SWR are far larger than needed elsewhere. Anything below 160M is a 'specialty' band that far fewer will attempt. However you COULD go through the values that the KAT500 offers manually and see if something could work. You could use an antenna analyzer in SWR mode (fixed freq not sweep) to tune the antenna at almost any frequency (at flea power, all legally).

[Elecraft] My K3 just wasn't working right today
I've had the K3 and P3 for a while. Bought them used from a SK estate. I've always felt that it hasn't quite worked 100%. I've followed the manual and Fred Cady's book about adjusting audio, gain, etc. Today for the DX contest, I just couldn't make consistent contacts, but I made some. Whenever I couldn't get a contact that I felt I should, I switched over to my Kenwood TS-590S on the same antenna, and made the contact. I'm not sure where to start troubleshooting this other than dropping off to Elecraft to have them check it. Any suggestions?

Re: [Elecraft] Where is Elecraft Support ?
You can always emulate the US Department of Defense if you'd like ... it's called a "Lifetime Buy." When the airplane builder's contract finally ends and he no longer is required to stock parts, the engineers and logistics folks decide on the further lifetime of the airplane fleet and buy enough parts to keep it flying until it will be retired to Arizona which might be in 20 more years. A lot of folk believe that science and engineering are the same thing. They're not. Engineering is science coupled with economics, logistics, mathematics, fabrication, maintenance, supply chain management, and a host of other trade-off's, sometimes including labor relations and law. Bell Labs "invented" the transistor. Companies like TI, Fairchild Semiconductor, Intel, Motorola, and AMD put them in the marketplace and they get to stop making them when something better comes along. See if you can find a Moto 68000 replacement for your old Mac. [:=) My K3 is S/N 642, and has been upgraded multiple times. I think it's about 10 years old and I think Elecraft has done a very good job compared to what the other guys do.

Re: [Elecraft] KAT500 antenna selection
"I didn’t say “set the operating frequency.” I said “tuning it.” I have complete manual control over L, C, and C side without transmitting. I can, therefore, set a tuning solution for any frequency bin within the KAT500 frequency range without transmitting. I can also recall a stored tuning solution for any frequency without transmitting. I think both would qualify as "tuning it". What would be true is that AutoTune cannot be performed without transmitting. What I actually wanted to do this morning was listen to WWV on 5 MHz and I wanted to use my 40 m dipole. That antenna was not selectable. I later found it could be selected if I changed the 60 m enabled antennas to include the 40 m dipole. 73, Andy, k3wyc __ 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 called support and they called me back and they admonished me (I've told this story many times) for not emailing them back. My email was in their spam folder. I can't think of a way around having spam filters, so you really do have to call them if you're not hearing back. __ 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

There was a rather odd piece of glue logic that I needed to implement the design. I called up TI and they assured me there were no plans to discontinue the part. You guessed it. Just as we were ready to go into production the part was discontinued. I had to scramble to figure out some other means to perform the function (which meant a PC board turn).

Re: [Elecraft] KAT500 antenna selection
Andy - You bring up some good points, and I will be watching for the input from the assembled brain trust. One issue I have with the KAT500 is that it only goes down to 160 meters. My previous tuner would handle much lower frequencies, allowing me to work 630 meters. No such luck with the KAT500. If there is a workaround, I'd like to hear what it is. Also keep in mind that tuning it on "off band" frequencies requires that you transmit a signal of at least a minimal value ... which is technically not legal. 73 Lyn, WØLEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Andy Durbin Sent: Saturday, March 07, 2020 11:10 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KAT500 antenna selection The KAT500 has continuous frequency coverage for saving and selecting tuning solutions and is not constrained to amateur band limits.
