WebInstead, the resonator is part of an "electrically-short resonant antenna" configuration, where the 'EA' effective aperture is immensely enhanced by resonant coupling to incoming EM waves. In other words, disconnecting the LC resonator doesn't cause your crystal radio to receive all AM stations at once. Instead, it goes silent, because the ... WebFIGURE 3. Early crystal radios used a natural galena crystal instead of a germanium diode to detect the audio modulation. The 1.5” diameter coil and variable capacitor form a resonant circuit to select the frequency and a …
