KJSR (103.3 FM, branded as "103.3 The Eagle") operates as a classic rock station licensed to Tulsa, Oklahoma. It is owned by Cox Media Group, with its broadcasting studios located in South Tulsa and its transmission tower positioned in western Wagoner County near Coweta, Oklahoma.
History
The station began operations in 1966 under the call sign KORU, a religious broadcaster owned by Tulsa televangelist Oral Roberts. Its studios and transmitter were situated within the Prayer Tower on the ORU campus. In 1972, ownership transferred to Central Broadcast Company, which changed the format to urban contemporary and rebranded the station as KKUL "K-Cool," also relocating the transmitter. In 1977, William H. "Bill" Payne purchased KKUL, and by 1978, the station shifted to a Top 40 format under the call letters KTFX, known as "The Superfox 103."
November 1979 marked a transition when KTFX adopted a country music format branded as "The Country Fox," becoming Tulsa’s inaugural full-time FM country outlet. This programming continued until 1995, when Cox Radio acquired KTFX and transformed it into classic hits under the new call sign KJSR with the branding "Star 103.3." Over time, this evolved into a classic rock format. Meanwhile, the KTFX calls and country programming were moved to 102.3 FM (currently News/Talk KRMG-FM).
On October 9, 2012, KJSR underwent a rebranding to "Rock 103," incorporating the Billy Madison Show and emphasizing harder rock tracks from the 1980s and 1990s. However, by April 10, 2014, the station rebranded again as "103.3 The Eagle," discontinued the morning show, and reverted to a softer classic rock playlist.
Additionally, KJSR is simulcast on Cox Communications digital cable channel 1981 in Tulsa. Traffic and weather updates are provided by KOKI.
