From 2006 to 2008, this station simulcasted XEPRS-AM as XX (pronounced Double X) Sports Radio. It aired San Diego Padres games and the entire talk show lineup from the AM station. Before that, it had various musical formats. When XX Sports Radio aired on FM, it helped spread the XEPRS signal to eastern parts of San Diego County. On April 15, 2008, the station broke away from the simulcast, and flipped to oldies/classic hits, branded as "105.7 the Walrus."
In May 2014, while promoting their "105 Walrus Days Of Summer", 105.7 began playing fewer songs from the late 1960s and early 1970s while adding more 1980s hits and de-emphasizing the "Walrus" name. Morning co-host John Nolan left the station in July, leaving Kim Morrison to do the show solo. Afternoon host Rich "Brother" Robbin left in August. On August 18, 2014, XHPRS became "Max FM," playing classic hits from the mid-1970s through the early 1990s. Jack Diamond became the new morning show co-host. Prior to a 23-year run at WRQX in Washington DC, Diamond had done mornings at country KSON. After 1 week of doing mornings, Diamond left the station and returned to Washington. Christina Martinez, formerly at KRTO in Guadalupe, California, is now doing afternoons.
