[3] WEDC began operations during a chaotic period when most government regulation had been suspended, with new stations free to be set up with few restrictions, including choosing their own transmitting frequencies.
[4] Following the establishment of the Federal Radio Commission (FRC), stations were initially issued a series of temporary authorizations starting on May 3, 1927.
[5] In addition, they were informed that if they wanted to continue operating, they needed to file a formal license application by January 15, 1928, as the first step in determining whether they met the new "public interest, convenience, or necessity" standard.
[6] On May 25, 1928, the FRC issued General Order 32, which notified 164 stations, including WEDC, that "From an examination of your application for future license it does not find that public interest, convenience, or necessity would be served by granting it.
[1] WEDC's original studios were located on Ogden Avenue at the car dealership known as Emil Denemark Cadillac, the owner of the station.
Soon after Pucinski's purchase of the station, WEDC's studios and transmitter were moved to the Jefferson Park neighborhood on Milwaukee Avenue on Chicago's northwest side.

At midnight on June 13, 1997, WSBC took over WEDC's hours, putting an end to the last of the original time-sharing arrangements in the United States.
