That little setup is resonant at 690 KHz. My secondary is not big but does have about 1000 turns on it. Its about 11 inches by 2 inches 30ga wire. I like making them like that to get a high...

Very Good! Now that you have some distance between the coils you can see how well they are really doing. When you have them close together you get capacitive and inductive couplings, not the true...

Hey, try hooking up your scope across the capacitor in you circuit. See how high of a voltage its getting as your adjusting things.

I prefer using AC for these small tests, you get twice the voltage on the primary that way. Even better is AC square wave, that will smack it real good and get an even greater voltage gain on the...

Looking good! Looks to me that your still not in tune though. These coils are very sensitive once you get them in tune, just putting your hand by them will knock them out of tune and you will see...

The wave forms look like your not in tune yet. They should be a pure sine wave that have a high voltage peak once in tune. The system will work much better one you get it in tune, I would hold off...

So your setup will resonate at around 688KHz without the coil B. That seems pretty low for how short of a coil you have. You added in a toroid or sphere for the topload capacitance? Im assuming...
