FM

Francesco Zantedeschi, Joseph Henry, Michael Faraday, James Clerk Maxwell, David E. Hughes, Heinrich Rudolf Hertz, Nikola Tesla, Jagadish Chandra Bose, Thomas Alva Edison, Alexander Stepanovich Popov, Oliver Lodge, Guglielmo Marconi, Edouard Branly and many others gave us this: the radio. Since this is a very simple mono FM radio receiver, tune somewhere from 87.5 to 108.0 MHz and wait for Roger Waters - Radio K.A.O.S. (Who Needs Information)
