I think before we describe what operational artifacts, roofing filters impact - someone needs to define what a ROOFING FILTER is? Is it different from the filters one buys for his IC-706? Why is it called a ROOFING FILTER? What job is a ROOFING FILTER supposed to do? What does ROOFING have to do with anything? Does it have some magical frequency response curve - I would see via my CAD program? Is it a elemental RLC type circuit - passive?
In other words - before one discusses the great uses of a positraction rear end in my chevy - for what reason was the positraction rear end designed for and what are its characteristics, in the first place? Why do I need a roofing filter - I guess that is what is bothering me ............... :) Fred, N3CSY __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
