List of temporary broadcasting stations in the United States is a review of broadcasting stations which were not issued standard licenses, but instead were given temporary authorizations, to be used for special purposes and limited time periods. In a small number of cases these authorizations were followed by a standard license, or this represented a short-term revival of a previously licensed station. However, in most cases the stations expired immediately after their intended purpose was fulfilled.

Information about these stations is somewhat limited. For the AM band stations authorized through 1928, the monthly issues of the Radio Service Bulletin, and the annual station lists issued by the U.S. government, regularly reported the status of stations operating under standard licenses. However, in general these publications did not include information about temporary stations, although basic information about these grants was included in station card files maintained by the government.

Stations

Temporary stations Call Initialtemporaryauthorization Location Owner NotationNotes for individual stations placed on two sets of cards (by call letter and city) maintained by government regulators, and filed in the deleted stations sections. These card files were started by the Department of Commerce in 1921, and were replaced after 1928, when the government switched to a new card file organization. Some abbreviations include: "RI" and "SR" for regional "radio inspector" and that position's later title, "supervisor of radio"; "TG" for "telegram"; and "761" for a submitted "Form 761: Applicant's Description of Apparatus".
