Dan -

This test and several others are easily found in my Tesla Coil Construction
Guide.  This book is over 10 years old and I have been wondering why it is
still selling. I now realize it is because it does have some advantages over
the archives. The book is available from me or Lindsay (815 935 5353) or
Twenty First Century Books (970 453 9293).

First, here is a classic example of how I couldn't find what i needed in the
archives yet i *know* this topic was discussed in detail only a few months
earlier.

Anyways, I want to measure the resonant frequency  of my secondary / toroid
assembly.

>From my recollection, you would inject a signal into the base of the
secondary, and then measure the output using some sort of antenna near the
top of the toroid connected to a spectrum analyzer???

Would someone be able to briefly describe the set-up, i think there was a
series resistor in their somewhere as well.

Thanks again.
