Here's an applications note I wrote for NCJ. Part One ran in the last 
issue, Part Two runs in the next.

Comments appreciated -- additions, critical, etc.

Dave, I STRONGLY recommend that you study your noise in an RF spectrum 
plot (as opposed to audio spectrum). The RF spectrum often yields far 
more clues. One of the first things you must do is determine whether you 
have impulse noise or electronically generated noise. If it's 
electronically generated, we must chase it at the frequencies where we 
hear it. If it's impulse noise, we can apply classic power line 
techniques to finding it.
