[Elecraft] P3 visualizing local noise

[Al Lorona]

I'm sure we could all go on for years listing all of the possible RF noise 
polluters that can produce such a distinctive pattern on the screen of the P3, 
but while searching your house for a source of RFI do not overlook those stylish 
fluorescent undercounter lights in your kitchen (or any other room) that your 
wife just had to have, which can really pollute surprisingly badly.
