Originally a station in the Corpus Christi area, the station moved in 2021 as part of a facilities shuffle that moved a third EMF signal into San Antonio (alongside existing K-Love outlet KZLV and rimshot Air1 outlet KZAR). The former 103.7 facilities and KXAI call sign were moved to another license, leaving Air1 programming seamlessly available to Corpus Christi-area listeners.
