[RFI] Visualizing Line Noise

[Jim Brown]

Pete,

My tutorial on identifying RFI shows that a spectrum scope with a 
waterfall display is probably the most effective tool for that. If you 
haven't taken the time to study it, I suggest that you do. SDRs can be 
bought for as little as $150, and the software is free.
