skeptical inquiry

Frank’s Spirit Box: A device created by Frank Sumption that generates white noise manipulated to coincided randomly with the voltage tuning of an AM radio receiver. This generates a moment of sound in the AM broadcast range of 535 - 1605 kHz, which is then acoustically enhanced. Sumption believed spirits could communicate via the modulated radio waves. The spirit box is largely dismissed as quackery, along with other random sound generating instruments such as digital dowsing rods and the Ovilus.
