Dear Pete & Topbanders,
For a high-pass filter with three nulls within the AM broadcast band, a good
construction article is in the 1985 ARRL Handbook, pages 30-32, I do not
have the chapter number. It is probably from an original article in QST in
1978. It uses Amidon iron power cores and common value silver mica
capacitors.
Ahah! It's still there, at least in the 2000 Handbook, page
16-36. Thanks, George!
