Have you studied Dave's material and mine? Two things we both recommend
are 1) buy or borrow an inexpensive SDR and install one of the many
freeware programs that lets your computer control it. 2) Set it to
provide a waterfall covering the frequency range(s) where you hear
noise, both to learn the character of the noise (electronic or power
line), and WHEN it's present. Does it go on and off at any regular
times? The slides for my talks list several inexpensive SDR receivers
that were available when I wrote it 3 years ago, and stuff like this has
only gotten cheaper and better.
