WHOO (1080 AM) is a non-commercial listener-supported Catholic talk radio station licensed to Winter Park, Florida, and serving Greater Orlando. It is an owned and operated network affiliate of Relevant Radio. By day, WHOO is powered at 6,000 watts. But 1080 AM is a clear channel frequency reserved for Class A WTIC Hartford and KRLD Dallas. So at night, to reduce interference, WHOO reduces power to only 55 watts. It uses a directional antenna at all times.
