[RFI] EMI/RFI AC line filter design info?

[Ray, W4BYG]

Thanks to all who replied to my question.  I got some good responses.  I
appreciate those of you who took the time to respond.

The Corcom info was interesting but at $55 apiece totaled more than I want
to spend.  I need a couple.   Thus, I prefer save the money and build/test
them myself.  

Jim, K9YC's comprehensive reply and .pdf (which I previously had read), was
very helpful also.

I had looked in my recent ARRL Handbooks and didn't find anything.  I didn't
think to look in my older 1956 ARRL copy.  I should have.  

I already had a LIST network made up for testing.  Now to my parts bins and
workbench.
