    Hello,

    The ringed part is a coil with a copper core for tuning.

    The transmitter will not be that stable as it looks like a free running oscillator using ceramic capacitors.

    Everything will cause that thing to drift; battery voltage changing, temperature changing, hand-capacitance, phase of the moon, etc. It is a toy...
