XHPRS-FM (105.7 MHz) is a commercial FM radio station transmitting from Tecate, Baja California, and serving the Tijuana-San Diego metropolitan area. It airs an English language classic hits radio format. Its studios are in San Diego's Sorrento Valley.
The concession history for XHPRS begins in Ensenada, Baja California, where the concession for XHBCE-FM was awarded to Gustavo Adolfo Paez y Vejar on November 16, 1988. In the early 2000s, under Roxana Alexanderson Torres, XHBCE began its move into the Tijuana area by soliciting a move to Cerro Grande to the east of Ensenada, coinciding with the station's change to 105.7 MHz, and then to Cerro Bola in Tecate. (XHHC-FM would later restore the 92.1 frequency to use in Ensenada.) By 2005, XHBCE was broadcasting a Spanish-language talk format known as La Pantera, embroiled in an interference dispute with KXRS in Hemet, California that threatened to cut off the station's access to programming delivered from the United States under FCC authorization.
From 2006 to 2008, this station simulcast 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 2010, it received authorization to change its callsign to XHPRS-FM, though it had been using the callsign for some time before.
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 one week at XHPRS, Diamond returned to Washington. Once again, Kim Morrison is doing the morning show solo. Christina Martinez, formerly at KRTO in Guadalupe, California, hosts afternoons.
