Thanks, Jim! OK, so far, so good. How lossy will this be? As lossy as, say, a long string of ferrite beads? If not, is that because of the increased inductive impedance? If it's as lossy as a string

As I was perusing type 31 material the Fair-Rite web site, I ran across a a material characteristic that is new to me: "Loss Factor @ Frequency." For type 31 material, the units are in 10e-06 MHz, th

Ah! My mistake! Apologies all the way round! Then, aside from the fact that the big cores can handle more power (via dissipation if nothing else), we can fit on more turns! Got it. Kim N5OP "People t
