By day, WTRU transmits with 50,000 watts, the maximum for AM stations in the U.S., but 830 AM is a clear channel frequency reserved for Class AWCCO in Minneapolis, so WTRU must reduce power at night to 10,000 watts. Programming is heard on three FM translator stations in the region. (See below.)
New towers were built outside Walkertown, North Carolina to improve coverage of the entire Greensboro-High Point-Winston-Salem market. In 1997, Hearst-Argyle Television, owner of area NBC affiliate WXII-TV, bought the station and changed callsigns to WXII, and a news radio format was used that included audio from some WXII-TV news broadcasts.[4][5] Truth Broadcasting bought the station in June 2000 and, after a few weeks of silence, returned it to the air with the current format and call letters.[6] From 1956 until 1992 the WTRU calls were assigned to the now silenced AM 1600 in Muskegon Heights, Michigan.
Translators
In addition to the main station on 830 AM, WTRU is relayed by three FM translators.
