[RFI] CASE HISTORY - Powerline - Multiple Sources (re-post w/o errata)

[Jim Brown]

Sorry, I must have missed that. There is an unfortunate assumption by 
far too many hams that power lines are the only source RF noise, 
ignoring all the electronic sources, which for any ham living in 
business or residential neighborhoods are often dominant.

That's why all of my advice on chasing noise is to first figure out what 
kind(s) of noise you have.

This can and does make it more difficult to locate the specific noise causing RFI to a ham radio station.
