Edwin Howard Armstrong (December 18, 1890 [2] – February 1, 1954 [3]) was an American electrical engineer and inventor who developed FM (frequency modulation) radio and the superheterodyne receiver system.
The film focused primarily [5] on the three pioneers [6] of radio in America: Lee de Forest, Edwin Howard Armstrong, and David Sarnoff. [7] The program interspersed audio and musical highlights of "old time" radio with the stories, achievements, failures, scams and bitter feuds between each of the main protagonists. [8]

Edwin Howard Armstrong invented the superheterodyne receiver in 1918. [1] Armstrong and RCA (under David Sarnoff) had a business and technical relationship, that would last into the 1940s. Funded by RCA, Armstrong designed a radio that can receive stations easily without complex tuning or interference from other stations.
When Marion met Edwin Howard Armstrong, she was the secretary of David Sarnoff, then an executive at RCA. [ 2 ] [ 3 ] Armstrong was then both an inventor and Professor of Electrical Engineering at Columbia University .
Edwin Armstrong and David Sarnoff tested and perfected the regenerative circuit at the Belmar site, on the night of 31 January/1 February 1914. Albert Hoyt Taylor, who later made important contributions toward the development of radar, was Communication Superintendent at the station during World War I. The station was closed in 1924, after ...
KE2XCC, first authorized in 1945 with the call sign W2XEA, was an experimental FM radio station located in Alpine, New Jersey and operated by inventor Edwin Howard Armstrong. It was located at the same site as Armstrong's original FM station, W2XMN, which dated to the late 1930s and primarily transmitted on the original FM "low band" frequencies.
Wide band Frequency modulation radio originated in the United States during the 1930s; the system was developed by the American electrical engineer Edwin Howard Armstrong. However, FM broadcasting did not become widespread, even in North America, until the 1960s. Frequency-modulated radio waves can be generated at any frequency.
