By day, WFJX is powered at 1,000 watts.[7] But to protect other stations on 910 AM from interference, at night WFJX reduces power to only 84 watts. Programming is also heard on 99-watt FM translatorW282CK at 104.3 MHz.[8]
The station signed on the air on April 1, 1957; 67 years ago (1957-04-01).[9] The original call sign was WRKE. It was a daytimer station, required to go off the air at night. The studios were in the American Theater Building.
The station later became WTOY with an R&B and Soul music format, aimed at Roanoke's African-American community. In the 2010, it switched its call sign to WFJX, airing a talk radio format, known as "Fox Radio 910."
