I built the circuit above, the most difficult is the construction of the 3 coils done by hand and checked with the LCR meter. With an input of 10.7 volts, 10 big leds of 3 volts connected in series on the avramenko plug light strongly following a precise adjustment of L1.
On a bandwidth span of 350 Mhz, this little beast is very very rich in harmonics, surprising how it being with this assembly I get 10.3 Mhz of central frequency. Very interesting experiment to do on coils behavior.

With a view on spectrum analyzer (TinySA), harmonics are very present all along the spectrum

You can see on the Spectrum Analyser a multitude of harmonics produced by spatial coherence at left starting a 0 hertz passing by 10.3Mhz under digit 1 and at right stop at 350Mhz. Resolution bandwith is automatic at 621Khz but i can change to have awider one.
Simply wonderful with lots of energy available.
It seems that this little beast is capable of taking even more. The following will be the addition of an additional load of 10 other LEDs in order to verify the consumption behavior (input power) of the circuit.
