Re: [Elecraft] P3 Failure, and question
My P3 does the same thing. If i keep cycling power it eventually comes on and works. I suspect there is a bad capacitor in the LCD backlight power. I have not actually looking into it yet. -- "If you are not the lead dog, the scenary never changes" Rick Stanback N4WCQ On Mon, 2021-04-12 at 04:41 -0700, Dave Cole wrote: > A bit more data: > > 1.

Re: [Elecraft] KPA500
My new KPA500 has started acting up again. It was coming up with Invalid in the display and no high voltage. I checked the aux cables and re-seated them and that seems to have cured the invalid error but I still get no high voltage. It was doing this after I first built the kit and then it just seemed to get over it and was working fine for about a week. Any ideas on what to check the manual does not really give you much to go on. __ 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] Noise Power Ratio and the K3 with new synthesizer?
I just completed the build of my KAT500 and KPA500 and I had the following issues. The KAT500: the software was very flaky trying to connect to the KAT. I run Fedora 21 so it might be the bleeding edge Linux. I did finally get the connect and hit the optimize for KPA500 button. I am still not able to hit the tune button on the KAT500 and get the K3 to xmit and tune. If I hit the button and then hit the tune button manually on the K3 it tunes? KPA500: When I first powered up the display would say KPA500 for a bit then Invalid?? Then if I put the amp to oper it would immediately get the 270v fault. I took it apart and inspected all the connections including the ribbon cables and although I did not find anything out of place or not seated when I put it back together it seems to just work? I have made a few contacts and everything seems to be OK. The amp follows the K3 band with no problems. -- Rick Stanback (N4WCQ) Chance only favors the prepared mind.

Here is a NPR tutorial from another source, for those interested and technically proficient enough to investigate further. 73, Scott, N9AA On 3/12/15 10:53 AM, Chip Stratton wrote: Adam Farson VA7OJ has an article in the current March/April 2015 QEX discussing the use of Noise Power Ratio (NPR) to help define a receiver's performance in a crowded band in a way that might be more illuminating than the simpler two tone tests. Its an interesting discussion which makes some sense, but then I'm not anywhere close to an expert in that field. In any event, he has figures from a number of transceivers, including a couple of K3s which no doubt do not have the new synthesizer. The K3s still performed very well relative the the rest of the field in these tests, though they were slightly behind the IC-7700, IC-7800, and TS-590S. Which of course makes me wonder how the K3 with new synthesizer would perform in this arena? From a guy with a mild metrology addiction...

Re: [Elecraft] linux K3 utility
It would sure be nice to have the sources so we could build the binaries for 64bit.
