B.W. Cooke was also the publisher of Automotive News in the 1930s. He was the director of the Chicago Motor Training Corporation in 1925. Coincidentally both of those were located in Chicago. An L.L. Cooke ran an electrical school with a similar M.O. just a few blocks away. I cant' prove it, but I suspect a family connection.
In April of 1925, H.C. Lewis purchased 1200 WTAY-AM from Oakleaves broadcasting. The station ran at a puny 15 watts. It's original calls were WJOC-AM but had to change them to avoid confusion with WJAZ-AM. It had only signed on in October of 1923. The call sign was changed about a year later to WGES-AM and increased it's power to 500 watts. Their own literature claims that it was a full time station but in fact it was a share-time with WMBB-AM. The station caused enough interference in downtown Chicago that besides losing money, it also obstructed the reception of many other stations. Lewis tried to sell it, then practically gave the station to Joseph Gunyon in 1929. Lewis was later wrote "I see absolutely no value in a school operating a radio station..." For more on that read Educations Own Stations by S.E. Frost. Their radio program continued even without the radio station. In 1960s, the Coyne Electrical School merged with the American Institute of Engineering and Technology.
