- Fixed Condenser, Used in the Hammond Radio Research Laboratory, circa 1911 - John Hays Hammond, Jr., was largely responsible for launching the field of radio control. In 1926, he built a medieval-inspired castle in Gloucester, Massachusetts. This site served as his home and research laboratory. With over 400 patents to his name, Hammond developed ideas for radio control, autopilot function, and targeted missile detonation. This device was used in Hammond's laboratory.

- Radio Goniometer Used at Ford Airport, circa 1927 - The radio beacon may be Henry Ford's most important contribution to aviation. Early pilots depended on landmarks, preventing reliable navigation in bad weather. Ford's engineers developed a radio beacon that simultaneously transmitted the Morse code letter "A" (dot-dash) in one direction and the letter "N" (dash-dot) in another. The pilot steered until the separate signals merged into a steady hum.

- Sparton Radio Model 558-B, 1937 - This 1937 Sparton radio was designed by Walter Dorwin Teague, a designer renowned for his use of streamlined forms. A study in contrasts -- the blue mirrored finish and curved sled-like base suggest speed while the five jutting parallel panels appear almost architectural -- this expensive and glamorous radio had a limited market during the Great Depression.

- Heathkit Portable AM Transistor Radio, Model XR-2P, circa 1962 - The Heath Company was founded in the 1920s as a "do-it-yourself" electronics kit provider. "Heathkits" provided simple, accessible instructions understandable to amateurs and experts alike. As hobbyists built radios, televisions, and computers from scratch, they gained electronics skills. These kits were not novelties, but emphasized access to affordable, advanced, high-performance technology. Parallels can easily be seen within present-day "Maker" culture.

- Zenith "My Radio" Pendant Transistor Radio, circa 1970 - The size of radios shrank following the advent of transistor technology. Even the smallest vacuum tubes were bulky, and their power consumption ensured the need for large batteries. Transistor radios made of lightweight plastics were cheap and truly portable. With the addition of an earphone a radio such as this allowed the listener to enjoy a completely personal listening experience.

- Dr. Vladimir Zworykin Showing a Vidicon Television Camera Tube, Dearborn, Michigan, 1958 - Vladimir Zworykin was an early pioneer of television development, employed by Westinghouse and the Radio Corporation of America. Here he presents a Vidicon camera tube, to be donated to the museum. Vidicon tubes allowed bulky, expensive broadcast television cameras to become smaller and cheaper beginning in the 1950s. Zworykin's iconoscope and kinescope picture tubes were breakthroughs in television history.

- Finch Facsimile Transmitter, 1938-1940 - From 1938-1940, the <EM>Detroit News</EM> experimented with a domestic radio-facsimile subscription service. This transmitter converted images and text into electrical impulses, sent over the radio waves--reassembled by receivers in the homes of customers. The idea was revolutionary, however, the process was slow and signal reception was unreliable beyond a mile or two of the transmission tower.
