Re: [Elecraft] Mysterious K3 Symptoms - RFI?
I recommend running fiber, but my old day job was in wired networking at a big chip manufacturer. I think fiber parts are getting a lot cheaper lately.

Initially, I was seeing a fair amount of noise from it, and was able to quench it by winding a couple of turns around a small clamp-on choke. That doesn't seem to affect the network performance, so I can reliably run it at 400MBit/second, and it seems to clean up whatever other noise it's picking up from nearby homes (most are on small lots of about 1/5 acre) and the condominium complex next door. I still have some strange noise from other sources coming in from the antenna, and the HVAC's air handler is very noisy, particularly on 30m through 15m, but I know it's not the twisted-pair Ethernet line. My CAT5E cable plugs into a small AC-powered router, and feeds my Mac, the K4D, as well as a laptop occasionally.

I have bought a shielded replacement but have not yet installed it. After reading some of the recent commentary about so-called "shielded" cables, I'm wondering if this is worth doing. Any suggestions, either K-3-specific or more general, would be much appreciated. __ 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 k2vco@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 ht...@twofifty.com -- Hisashi T Fujinaka - ht...@twofifty.com BSEE + BSChem + BAEnglish + MSCS + $2.50 = coffee __ 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
