Consider a common mode choke formed by winding turns of the cable carrying the noise through a #31 or #43 ferrite core. Use only #31 below 5 MHz. Both work well above 5 MHz, #43 is slightly better above 20 MHz. See my RFI tutorial for more detailed advice. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
