@ slayer007

I suggest you try this circuit (but I make no promises).

Is there actually a capacitor there are is this just representational?

There is no physical capacitor, but there is actual capacitance. It is between the wires in the coil. That and the capacitance between the metal plates creates the parallel capacitance that the inductor resonates with. About 1 pF total should make coil resonate at a few MHz.

@xee2,
I keep failing to find the information.
I can get close.
Maybe you can help.

How many coulombs or is it joules are in that 1pF that is resonating at 1Mhz?

thank you,

jeanna
