Hi Harold,

Well, I'm curious about -61 too. Turns out I have some FT50-61's (or
so claimed by Baggy Bob...), and I have FT50-67, FT50-68, FT50-43,
T50-1, T50-2, T50-3 and T50-7 to try for comparison. Unfortunately,
we're out of T50-6, but maybe I can arrange a test on a different -6
against the same size -2, at least. Not sure if I'll get to the coil-
winding and testing today, though.

Cheers,
Tom

Well, if you're going to put it off, I can send you a few T50-6's. Probably
some -10 material too. BUT! I want your results when you get them! If you
have them in a filter, would need to know the operating Q as well, but if
just the toroid itself, wonderful to have.
