KZDC (1250 AM, "ESPN 1250") is an all-sports-formatted radio station in San Antonio, Texas, owned by Alpha Media.[2] Most of the programming comes from ESPN Radio. Its studios and offices are located on Eisenhauer Road in Northeast San Antonio.
KZDC broadcasts at 25,000 watts by day using a non-directional antenna. 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.[3] 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.
