- Hope you can help: In trying to resolve several different interfering sources, I am wondering about how to best identify powerline noise vs other types. I always believed Powerline noise to be be ver

- I hope Mike will respond, but in the meantime.. Real "powerline" noise is broadband, but that isn't necessarily to say that noise with significant 60/120 Hz components can't be narrow-band. As an ane

- Greg, one only needs to drive down the street while listening to a low frequency power line noise to find the answer to your question on bandwidth. The power lines are the unmatched antennas for radi

- Greg, I think "narrowband" sources that have lots of 60Hz and harmonics in them might be things like light dimmers and switching power supplies that operate at a higher carrier frequency. Let's say

- OK, here's a picture of what happens on 160m when a 10kHz square wave source is modulated with a 60Hz filtered square wave (Don't worry about the filtering, I thought it was necessary, the picture i

- TNX to everyone for the detailed replies ! An excellent source of knowledge on this group. I has certainly given me much to chew on and helps me understand the complicated possibilities of RFI.. TNX
