The WLW studios are located in Sycamore Township (with a Cincinnati address). The transmitter is a uniquely constructed diamond-shaped Blaw-Knox tower in nearby Mason. Besides its main analog transmission, WLW simulcasts on 99 watt FM translator W233BG at 94.5 MHz and on an HD digital subchannel of co-owned 107.1 WKFS. The station is authorized to transmit an in-band on-channel digital signal, although it is not currently doing so. The station is a primary entry point station in the Emergency Alert System for Southwest Ohio, Kentucky and Eastern Indiana.
