Wait a second...you say the distance was 25ft between yours and their coil.
Did a fluorescent light bulb (or tube), or any other object, light up at
that distance as well? Or JUST the *TUNED* coil?

I know you believe that you understand what
you think I said, but, I am not sure that you realize
that what you heard is not what I meant.
