This event is part of NMIH’s “Don’t Touch That Dial: 100 Years of Radio” exhibit.  Radio employs the magic of sound by harnessing the electromagnetic radiation around us. The impact of radio is immeasurable. It has the power to elect political figures into office, it influences consumers to purchase certain products, it shapes new ideas and spreads news to mainstream America and it brings pleasure to audiences all over the world. “Don’t Touch That Dial: 100 Years of Radio” features over one hundred historic radios, components and ephemera. Visitors to this interactive exhibit can listen to early broadcasts, see an amateur radio operator’s station, test their knowledge of Morse Code, and experience modern day innovations in the industry.
