KZDC broadcasts at 25,000 watts by day using a non-directional antenna. But to avoid interfering with other stations on 1250 AM, it drastically reduces power at night to 920 watts and uses a directional antenna. The daytime transmitter site is just off U.S. Route 281 near Interstate 410, in the Mission del Lago district of San Antonio.[2] The station uses a separate nighttime site which is co-located with sister station KTSA 550, along Eisenhauer Road in Northeast San Antonio, across the street from the studios.

KZDC is also heard in San Antonio and adjacent communities on FM translator 94.5 K233DB.[3]

History

The station was assigned the call sign KHBL on March 1, 1994. On November 14, 1994, the station changed its call letters to KZEP. Then on April 1, 1995 to the current KZDC.[4]
