- Radiola Broadcast Receiver, Type 1375, Used at Tuckerton Wireless Station, 1922-1923 - This radio equipment was used at the German-built Tuckerton Wireless Station in New Jersey. A powerful 820-foot antenna communicated with an identical station in Germany. National security concerns during WWI led to the seizure of Tuckerton by the U.S. government in 1917. It is cited to be the origin of information leaks leading to the RMS <em>Lusitania</em> disaster through U-boat attack.

- RCA Radiotron Vacuum Tube, Model WD-11, 1923-1924 - Vacuum tubes appear in older radios, televisions, amplifiers, computers, and other electronic devices. Their function: to amplify and strengthen weak electronic signals. Typical tubes are sealed glass bulbs evacuated of gas, allowing electron flow to be influenced by an interior cathode, plate and grid. Perfected in 1906 by Lee De Forest, the vacuum tube was the genesis of a communications revolution.

- RCA Radio Tuner, 1925-1930 - By the late 1920s, radio tuners, detectors, amplifiers, and loudspeakers began to condense into one unit, housed within an attractive wooden or metal cabinet. The standalone nature of this radio tuner puts it in an earlier era of radio -- as a field for amateur operators, commercial technicians, and military communications experts -- rather than the domain of "passive" home listeners.

- RCA 45 rpm Record Player, Model 6-JY-1C, 1949-1951 - The 45 rpm record format was developed at RCA in 1949 under the leadership of David Sarnoff. The 45 format typically held one song per side, requiring active forms of listening. This record changer allowed stacks of durable 45s to be set on the top spindle; as each record finished playing, a new record would drop down onto the turntable.

- Faradon Variable Mica Condenser, Model UC-1819, 1920-1925 - Early radios containing vacuum tubes needed both AC (alternating current) and DC (direct current) electrical power to operate. Condensers (also known as capacitors) allow alternating electrical currents to pass while blocking direct currents. Condensers can block, pass, filter and tune the various currents of the radio.
