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.

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