➦In 1922...WOAI San Antonio signed on the air. At first, it broadcast on 1190 kilocycles with only 500 watts. Over the next several years WOAI was issued permits by the Federal Radio Commission to move the transmitter site and increase its power from 500 to 1,000 watts; then to 2,000 watts, and then 5,000; and finally to 50,000 watts in 1930.Meaning of call letters: World Of Agriculture Information.
During The Golden Age of Radio, WOAI was an NBC Red Network affiliate, airing its schedule of dramas, comedies, news, sports, soap operas, game shows, children's shows and big band broadcasts. For more than four decades, WOAI was owned by Southland Industries, Inc.
Because it went on the air in the earliest days of broadcasting, the station's call sign begins with a "W." Stations in Texas were in the W territory before 1923, when the dividing line became the Mississippi River. From that point, nearly all stations in Texas received "K" call letters. But WOAI has been grandfathered with its unusual call sign.
Today, WOAI is currently the westernmost station to have "W" call signs. There are still about two dozen W stations in states west of the Mississippi River.
In 1941, WOAI was moved to clear channel frequency 1200 kHz.
➦In 1933...The Tom Mix Radio Show was heard for the first time on NBC. The show ran until June 1950.
Thomas Edwin Mix was born Thomas Hezikiah Mix on January 6, 1880 and died October 12, 1940. He was an American film actor and the star of many early Western movies between 1909 and 1935. Mix appeared in 291 films, all but nine of which were silent movies. He was Hollywood's first Western star and helped define the genre as it emerged in the early days of the cinema.
Mix himself never appeared on these broadcasts (his voice, damaged by a bullet to the throat and repeated broken noses, was not fit for radio) and was instead played by radio actors: Artells Dickson (early 1930s), Jack Holden (from 1937), Russell Thorsen (early 1940s) and Joe "Curley" Bradley (from 1944). Others in the supporting cast included George Gobel, Harold Peary and Willard Waterman.
