Resonant frequency of an LC resonator
L = LμH*10^6;
C = CpF*10^12;
ω = 1/sqrt(L*C);
f = ω/(2*pi);
fkHz = f/10^3;
print(fkHz);

f = ω/(2*pi);
fkHz = f/10^3;

| f | kHz |
Daiso’s 1.0 mm diameter aluminum adjustable wire,
18.8 m (110 yen including tax), has
an inductance of 515 μH and a resistance of 0.86 ohms.
It is insulated by the oxide layer on the aluminum surface,
so it can be used as a coil.
For receivers like germanium radios, the voltage rating is no problem!
828 kHz is the frequency of NHK Radio 2 in Osaka;
it resonates at 71.7 pF.
