Knocked this up, It's a push-pull Hartley, had no joy with the Royer setups.
It's running at 82KHz, radiation on 2nd harmonic about 6mtrs on my Sony, 5th harmonic 2m, 10th <1m. I will compare it with a 500W PC supply tomorow.
I attach a pic of it running a 6V 3Watt bulb across 15mm of wood. the frequency of the Rx coil has not been optimized for resonance.
