I am reading your script and I wonder if you tested your resonant frequency
to determin compatibility befor you started your test. Your turns are nearly
the same, but are your turns per inch the same. I guess what I am asking is,
is the inductance/ frequency of each coil the same, If not you have added
another variable that is not accounted for in your test. Just my thoughts.
