Without the heavy 50Ohm load and a simulation speed of about 1us/s its working fine, tank 3.3uH and 30nF caps. But this circuit seems to be still under construction and changed a lot ;)

Yes, I should have waited before posting it ;-) I finally got it working, and changed the parameters with the components I actually intend to use, it works in the simulation but not in real...

Yes, cuz 100nF with 320nH is a bit optimistic combination. I would at least go up x10 in inductivity and for the cap go down. This is because of impedance, you have now is around 2.4Ohm. Ten or 100 times higher should work much better. Keep it up!
