Which se band covered vy receiver ? It seems starting from 264MHz to over 2GHz, are you sure about the value 1nH?

Sorry the inductor value is supposed to be 100 turns of magnet wire

To calculate Henry of windings you need more parameters, like thikness of wire and diameter of inductor. Otherwise, knowing the minimum frequency to be reveived, at resonance reactance are equal one each other so 2*pigreek*f=1/rootof (L*C) where f is your minimum frequency, C is your cap in farad. Inverting formula, you can determine your L inductor in Henry.

If you receive in MW (medium wave) your L coud be around 300microH

If you search in the store for some app coils calculator, you can calculate your inductor
