It might also make sense to increase the turns to 14, which would give a
coupling factor of 23 dB, and much more safety margin.

Larry,
Thanks! 200W is probably a bit on the high side for my needs (safety
margin), so this looks pretty good.

A quick check shows that no small size cores will work for -43 material
with 10T at 1.8 MHz and 200W. However, FT50B cores come close, and are
fine at 3.5 MHz. FT50B is twice the thickness of the FT50A, and would
fit on the board because the thickness would only add height.

Larry,
If you have the time, I'd certainly appreciate it if you'd run it
through your spreadsheet for me.
Thanks! -Michael
