KSBJ Educational Foundation was granted a license to cover for the facility on August 17, 2005. It was originally licensed as a Class C2 facility with its broadcast tower in the city limits of Bay City, but downgraded to the current C3 classification, with 13 kilowatts ERP, and moved further southwest in Matagorda County in order to accommodate the move of parent station KSBJ into the Houston city limits.[4]
On August 20, 2021, KZBJ's callsign was changed to KVUD. On September 16, 2021, Hope Media Group announced that NGEN Radio would be moved exclusively to digital distribution on its website and app on November 8, at which point a new, undisclosed format would launch on KHVU, KVUD, and KVUJ.[5] On August 31, 2021, Hope Media Group registered the trademark Vida Unida, presumably the new format for these stations.[6] On November 10, the stations flipped to SpanishChristianadult contemporary "Vida Unida".
