Studios for KTBB-AM-FM are co-located with KRWR in the Woodgate Centre office building at 1001 ESE Loop 323, at the intersection with New Copeland Road. The transmitter is off County Road 283 North in Whitehouse, Texas. By day, KTBB is powered at 5,000 watts. But at night, to protect other stations on 600 AM, KTBB reduces power to 2,500 watts. It uses a directional antenna at all times.[4]
