Sarnoff also demonstrated the first use of radio on a railroad line, the Lackawanna Railroad Company's link between Binghamton, New York, and Scranton, Pennsylvania; and permitted and observed Edwin Armstrong's demonstration of his regenerative receiver at the Marconi station at Belmar, New Jersey.
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]
Although most early radio receivers used regeneration Armstrong approached RCA's David Sarnoff, whom he had known since giving a demonstration of his regeneration receiver in 1913, about the corporation offering superheterodynes as a superior offering to the general public. [28] (The ongoing patent dispute was not a hindrance, because extensive ...
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.

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 ...
In 1933, FM radio was patented by inventor Edwin H. Armstrong. [74] FM uses frequency modulation of the radio wave to reduce static and interference from electrical equipment and the atmosphere. In 1937, W1XOJ , the first experimental FM radio station after Armstrong's W2XMN in Alpine, New Jersey, was granted a construction permit by the US ...
