Hi Mustefa,
The resonant frequency of L1 and 22pF capacitor is not connected with the oscillator frequency but is related to the phenomenon and is quite critical and perhaps depends on the country. In my country and in Switzerland also work well for L1 2 turns, but do not turn 1 and not working 47-68-82pF capacitors. Great work for your pcb and for this of Indiana Jones.
Best Regards
