However, some moron claimed in QST that steel wool was just as good as
ferrite for making choke baluns, but I've forgotten who the lunkhead
at the League was who believed him, and allowed stupid idea to be
published.

I complained to the League editors, who unbelieveably said 'Prove It'.
So I bought some steel wool and made two back to back baluns with it
and made measurements of common mode currents. The measurements proved
that the steel wool had absolutely no choking effect.

I reported the results of the measurements to the editors at the
League, but I can't remember whether they did anything about refuting
the original incorrect material. Perhaps your memory is better than
mine on this issue.

The results of your measurements were published in "Hints & Kinks" in
September 1993 QST. According to the editorial comment accompanying it,
you were prompted to make the measurements by Tom Rauch, W8JI, who had
done some measurements which indicated that the steel wool balun was
ineffective. The Hints & Kinks editor at the time, who had accepted both
the original contribution by Curt Wilson, W0KKQ and yours, was Dave
Newkirk, WJ1Z. Anyone interested in learning more about it should read
the Hints & Kinks submissions and note Dave's added editiorial comments.
