Sometimes you can "get a feeling", where they are located by watching the timing... Do they drift in the morning, and after sunset, if so, the SMPS might be outside, on in a non temperature controlled area, if not it might be inside... Do they happen at set intervals? Time to do the power off test to your home and see if they go away... If you are lucky they will... If they do, bring the house up one breaker at a time, looking for the RFI to start... If not, then set up S-Meter Lite, look for patterns, then after a week or so of recording what is happening, take out a loop and start looking for it... -- 73's, and thanks, Dave (NK7Z) For software/hardware reviews see: http://www.nk7z.net ______________________________________________________________ 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
