 From there, the broadcasting facilities were moved to a main studio at 402 Fayette Street, Fayette and Hohman Avenue, which today sits the former home of Bank Calumet (Calumet National Bank Building).It remained at that address until the station was sold to O.E.Richardson, Fred L. Adair, and Robert C. Adair, and the callsign was changed to the present WJOB on October 7, 1940.
