I just happened across something out of an old book that may be of interest from the 160 meter portion of the book.

Part of the text from the book.

I'm happy to type up the full text (over a page of it with four additional diagrams) if you think it will help in any way. I have noticed that in the next versions of the ARRL antenna book that I have (10'th edition and beyond) this information is not present, at least it is not in the 160 meter chapter.

It seems with this design you use a field strength meter while tuning. You start with the tap at the bottom of the inductor near the top hat, then tune the bottom circuit and measure field strength, then raise the tap on the coil, tune the bottom circuit again, measure with a field strength meter again, and repeat until the field strength peaks. I'm wondering if an analyzer could speed up this process any.
