By day, WTWB is powered at 5,000 watts. But 1570 AM is a Mexican clear-channel frequency in which XERF is the dominant Class A station. So to avoid interference, WTWB greatly reduces power at night to 13 watts.[3] Programming is also heard on two FM translator stations: W224CF at 92.7 MHz and W238CV at 95.5 MHz, both in Auburndale.
