Topband: Two 2:1 transformers to choose from!!

[Mike Waters]

P. 7-69 of Low Band Dxing (5th ed.) by ON4UN says a maximum of 4 turns on
the low-Z primary for binocular cores. It might work, but there are other
turns ratios you might try.

Here is a list of turns ratios for those cores I made:

it to you.
