NK7Z's website has waterfall and spectrum plots of a wide variety of 
KNOWN noise sources. It would be a good starting point. His website and 
mine both include lots of detailed advice on identifying the type of 
source, and for chasing and killing it. On my website is a piece that 
ran in two parts in NCJ several years ago, as well as slides for talks 
that I've done at ham conventions and clubs. k9yc.com/publish.htm
