- 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.

- 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.

- Transmitter, 1917 - This quenched gap radio transmitter -- a type of spark gap transmitter -- would have transmitted radio waves used for Morse code signals in ship-to-shore communication. Spark gap transmitters, which used an electrical spark to generate radio waves, were the first means of practical radio transmission for the first thirty years of radio development.
