This is another great magazine about early-day radio, and one not published by Gernsback. In the early 1920's the Citizen's Radio Service Bureau (508 South Dearborn St., Chicago IL) began publishing lists of radio stations, with location, frequency, power, and programming descriptions, and selling them to the same people who were already buying RADIO NEWS. Probably from the first, and certainly by 1926, each issue sold ad space, and contained both consumer-oriented and technical articles on radio and how to listen to it. They also published lists of amateur radio operators and their call signs. You can read more about this magazine in the CALL BOOK Profile pages.
