- Cats-whisker_detector caption "A "Perikon" detector, 1914. Instead of a wire-to-crystal contact, this had a crystal-to-crystal contact. The bornite crystal ' on the adjustable arm was moved forward until it touched one of the zincite crystals on the carousel '. Multiple zincite crystals were provided because the zincite was vulnerable to damage from atmospheric electricity.".
- Cats-whisker_detector caption "Carborundum detector. This used a metal clamp contact instead of a delicate cat's whisker, so carborundum detectors were used in military and shipboard stations where vibration could be expected.".

- Cats-whisker_detector footer "Cartridge carborundum detector from 1925. Crystal detectors were also used to a limited extent in vacuum tube radios because they were more sensitive than vacuum tube detectors. The carborundum detector was used, since it did not require adjustment and so was made in the form of cartridges".
- Cats-whisker_detector footer "The carborundum detector required a DC bias of several volts, provided by a battery and potentiometer.".

- Cats-whisker_detector comment "A cat's-whisker detector (sometimes called a crystal detector) is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral (usually galena) to make a crude point-contact rectifier. Developed around 1904 by early radio researchers Henry H. C. Dunwoody, G. W. Pickard and others, this device was used as the detector in early crystal radios, from the early twentieth century through World War II, and gave this type of radio receiver its name.".
