I measured yesterday the resonance frequencies of my secondary. It is a
4.3" diameter PVC tube, winded for a length of 19.7" with AWG 26 wire.
I got the following results:

324 KHz
813 KHz
1475 KHz
1766 KHz
2053 KHz

These without any top toroid or sphere. I used a function generator (sine wave)
and oscilloscope.

I was waiting to measure the fundamental and all odd harmonics (x3, x5, etc.)
but can anybody explain to me how I have got the above readings?
