The Disruptive Technologies that Changed the Course of RCA’s ‘Radio Central’

By John Schneider W9FGH

     It was the world’s largest radio station. It was said in 1922 that RCA’s “Radio Central” at Rocky Point, Long Island, New York, was the only station that could be heard anywhere in the world at any time—day or night. For a long time, it ruled the airwaves. But as John points out, every technology has a shelf-life. The colossus at Rocky Point would not be an exception.


The Neutrodyne Patent and the Freed-Eisemann NR-5

By Rich Post KB8TAD

     In the early days of radio, nearly everything about a radio was either patented, infringed upon, or in litigation. Rich tells the story the Freed-Eisemann NR-5, that featured a circuit that greatly improved sensitivity in Tuned Radio Frequency receivers. It wouldn’t be long before the startup that built the Freed-Eisemann receiver that used the circuit would be involved in a real-life radio courtroom drama.


US Route 66 and Los Angeles Radio History

By Richard Fisher KI6SN

     Southern California is known worldwide for its tangled freeways, sunny beaches, and hot cars. One hundred years ago, they all came together in a Hollywood-like stroke of serendipity. SoCal’s first viable commercial AM radio station launched in 1922, just four years before the opening of US Route 66, which “winds from Chicago to LA,” as Bobby Troub wrote in his tribute the fabled highway. Acting like a beacon, SoCal’s radio stations drew cars to LA for the next 100 years.


WSM: The Air Castle of the South

By Mark Haverstock K8MSH

     Nashville’s Grand Ole Opry would never have existed if it wasn’t for WSM AM radio. In 1925 the National Life and Accident Insurance Company needed to promote its insurance business and decided to launch a radio station to advertise their service. The key was the programming: old-time fiddling, traditional American folk music, a big dose of country humor along with more high-brow classical music and opera. It wasn’t long before the opera faded, and the Opry took centerstage.


Graynella Packer: Wireless Trailblazer (Part 1)

By Scott A. Caldwell

     Wireless telegraphy, whether land or sea-based, peaked the imagination of many young people in the early years of the 20th Century. But it was a man’s world, until a few intrepid women intervened. Graynella Packer became the first, but by no means the last, woman to pound the key in the wireless cabin at sea. Scott tells the story of their hard-fought battle to ride the airwave and the ocean waves.
