[Amps] Swan Mark 1 on 160 meters

Don't forget that a toroid is a 'one-turn loop' that can couple to other things.

I clearly understand that, and I'm pointing out how you and other 
designers can figure out which materials are suitable for THOSE uses, 
which are inductive. You clearly did not read or study my post. I 
suggest that you carefully study it and use what you learn to study the 
Fair-Rite data.

Your post suggests that ALL magnetic materials in toroid form are all 
same, but, in fact, there are HUGE differences between magnetic 
materials made as toroids. We've used resistors with radial leads for a 
century, but all resistors are not the same. And so on.
