Hello William,

Get a copy of Amidon's catalog which gives detailed suggestions for
powdered iron and ferrite materials, based on many years of experience.

Absolutely. I literally wore one of those catalogs to the point where you
could see through several pages.

Then there are the ARRL Handbook and their Antenna Book. Both well worth
every penny.

Regards, Joerg
