FWIW, I have greatly reduced RFI issues by using rs-232 serial cable connections. I went with them because I have found USB cables seem to be pipelines for computer hash to get into my rigs. I just got tired of experimenting with ferrites every time I changed computers or connection schemes. I build my own cables out of cat 5 or higher UTP cable. StarTech makes great one- and two-port high speed PCI and PCIe rs-232/422 boards that work well with desktop computers. No issues with N1MM, winkeyer serial and NAP3.
I also use WIFI exclusively in the shack (when operating) as I discovered my cable modem, located downstairs in the mud room "DMARC", propagates an unacceptable amount of hash into any rig when I connect shack computers to it via ethernet cabling. WIFI is a great way to reduce cable count too. $0.02 PS: all ideas above courtesy of K9YA's excellent RFI Cookbook. -- de AB1VL NAQCC #6799 ab1vl.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
