I am assuming you meant 'over 500 kHz' above. For a smaller coil, say
with a secondary coil 3.5" diam x 15" tall what would be a good
operating frequency? I have many different size toroids, so I could
probably tune it into many different freqs. The coil isn't working right
know (don't know what happened to it) so I am going to try to start
redesigning it better. I would like to know more about the effect of
different freqs and if it changes between small and large coils.
Could anyone help me out?
