Several changes were made based on his suggestions. The receiver was redesigned and reissued as the SCR-54 (Set, Complete, Radio). Since there was high demand, several companies produced these sets or components, including DeForest Radio Telephone and Telegraph, Liberty Electric, Wireless Specialty Apparatus, Marconi, and General Radio.

[3] [4] German physicist Heinrich Hertz built the first experimental spark-gap transmitters in 1887, with which he proved the ...

The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
Following the start of World War One in Europe, the United States declared its strict neutrality in the conflict. Due to concerns that radio stations could be covertly used to aid a belligerent, on August 5, 1914 President Woodrow Wilson issued an executive order imposing monitoring and censorship of their transmissions.
