Because the station broadcast an analog signal on channel 6, its audio could be received at 87.75 MHzFM. Originally carrying a Spanish format, the station's audio programming changed to sports with ESPN Deportes Radio on July 7, 2010, with English-language local programming on July 27, 2010.[3][4] The English language programming was soon moved to KDSP 102.3.
The station received its license for digital operation on July 12, 2021, changing its call sign to KXDP-LD, at which point the analog radio signal went silent.
On July 18, 2021, KXDP-LD received special temporary authority from the Federal Communications Commission (FCC) to air its audio signal on 87.75 MHz FM again. On July 20, 2023, an FCC "Report and Order" included this station as one of 13 "FM6" stations allowed to continue to operate an FM radio broadcast, as a "ancillary or supplementary" service.[5]
