The FM broadcast wouldn't be affect on an FM radio since noise is "Amplitude" in nature. FM rcvrs won't pick them up (usually, although some rcvrs may). Most powerline noise sources, when you are in

Jim, This has drifted far off from where the original question was, which was how to make/use a loop on 40 mtrs to track noise. I was simply giving some "general" guidelines from my experience and th

That's why, as I mentioned previously, one of the guidelines in the RFI books and followed by good RI investigators is to track the noise at the highest freq at which the noise can be rcvd moving hig

Don, I think David was trying to imply that the telephone usage may've caused the crash. There is absolutely no evidence of this nor that it was shot down--nearest F16 was over 150 miles away. There

My apologies to David if I misread his statements. You're correct. It could've meant many things. It's just there's so many "theories" out there with no evidence to support them, and so much evidence

That bandwidth sounds a little large for typical Taiwan non-UL listed touch lamps, so maybe it's something else. I have found most lamps to be around 40-50Khz wide every 170-180Khz (oscillator freq).
