50,000-Watt AM stations

This list includes AM stations in the United States and Canada that broadcast with a power of 50,000 Watts day and night. Some of these stations are what was once known as the "clear channel" stations; others are not. The fourth column shows the station's antenna pattern:

U4 Directional

Most of the original "clear channel" stations are nondirectional 24 hours. Some stations, such as WBZ, could operate as nondirectional, but instead use a directional pattern to avoid sending large amounts of signal into the ocean. The formats and call letters on this list are probably not 100% up-to-date, so send any updates to wowradio@wowradioonline.net.
