Germanium Diode Crystal Radio at Beth Kimball blog

Germanium Diode Crystal Radio. The 1.5” diameter coil and variable. The construction of crystal radio is simple with just four components includes antenna, earth connection, germanium diode, and a. The diode resistance rd of germanium diodes is most times rather low, and only useable in crystal receivers with a low q (low sensitivity and low. These days the envelope detector is a point contact diode such as a 1n34 germanium. The test setup uses an accurate rf synthesizer, a homemade am pin diode modulator driven by an audio generator, a. Early crystal radios used a natural galena crystal instead of a germanium diode to detect the audio modulation. A crystal radio is basically a high q resonator tied to an antenna and an envelope detector. Over the past few weeks i’ve had time to examine many dozens of diodes, mostly germanium, in my crystal radio diode collection.
