[RFI] Common-Mode CHoke

[Kimberly Elmore <cw_de_n5op@sbcglobal.net>]

I have a naive question: I've come into some FT-240 type 31 toroids. I'd like 
to make them into common mode chokes. I've read about the types that use 6-12 
large toriods with 4-5 turns of coax as common mode chokes. Would 10 bifilar 
turns of 16 ga magnet wire (twisted to a couple of turns per inch so as to keep 
the two wires together and simplify he winding) through a single FT-240 work 
about as well? If not, why not?
