History.
Urban AC and Classic Rock.
The station began broadcasting in 1976 with the call letters KAEZ. The call sign stood for "Eazy 107" and it played an urban adult contemporary format that included a wide-ranging playlist of R&B, soul, jazz and blues. The station played very little hip hop or rap music in the early 1980s. KAEZ remained on the air until November 23, 1985, when the station had a fire that silenced the station along with going bankrupt causing the station to be sold to Price Communications. 
On February 25, 1986, the station returned to air. The call sign was changed to KIMY ("My 107.7") and it switched to adult contemporary music. Then on August 7, 1987, it switched to classic rock as KRXO. The classic rock format stayed in place for 26 years.
Ownership changes.
On July 15, 2012, Tyler Media entered into an agreement with Renda Broadcasting to purchase that company's Oklahoma City radio stations. That cluster was made up of KMGL, KOMA, KRXO and KOKC, and the price tag was $40 million. 
In accordance to limits imposed by the Federal Communications Commission on the number of radio stations a single broadcasting entity can own in a single market, Tyler sold KTLR and KKNG to WPA Radio for $1.6 million. Tyler's purchase of KRXO and its sister stations was consummated on November 13, 2012.
Switch to Sports Radio.
On July 10, 2013, Tyler Media announced that the station would adopt an All-Sports format, and be known as "107.7 The Franchise" replacing the station's longtime Classic Rock format. That programming and format moved to KRXO-HD2, a digital subchannel which is also simulcast on translator K283BW at 104.5 MHz. Programming includes University of Oklahoma Sooners football and basketball, as well as NFL games on Sunday, Monday and Thursday nights. 
On September 16, 2015, Tyler Media filed to change the call sign to "KRXO-FM" and move the "KRXO" call sign to a co-owned sports station in Tulsa. The call sign change to KRXO-FM occurred on September 23, 2015. The Tulsa station shares some Oklahoma-based sports programming with KRXO-FM.
HD Radio.
KRXO-FM along with its sister FM stations in Oklahoma City including KOMA and KMGL transmit an HD Radio signal. That allows them to transmit the main programming on their first digital subchannels, while second and third subchannels carrying other programming for listeners with HD Radio-capable receivers.
In 2005, Tony Renda Jr., the general manager of Renda Broadcasting, said his company had signed a deal with iBiquity to start offering HD Radio on the company's 24 stations in Pennsylvania, Florida, and Oklahoma in 2006.
During the spring 2008 ratings period, previous KRXO owner Renda switched off their HD signals on all three of their stations in Oklahoma City including KOMA-FM, KMGL-FM, and KRXO-FM — because of coverage issues. "It's a temporary problem," Don Pollnow, Renda market manager said at the time. "Our engineer is working on it with the manufacturer."
University of Oklahoma sports fans with radios at the stadium had complained that the station's play-by-play was behind the actual game action. As a result, KRXO's HD Radio digital signal is often disabled during its University of Oklahoma football broadcasts.
