The station is currently owned by the Bible Broadcasting Network.

WDYN began as the campus station for the then-Tennessee Temple College in 1968.

In November 2010, Tennessee Temple sold the station's transmitters and frequency to Bible Broadcasting Network for $2.5 million as WYBK.

[2] The school retained the studio facilities, and continued to broadcast on the internet.

The school subsequently purchased WUUS (AM 980) from 3 Daughters Media for $175,000,[3] and began broadcasting its signal on that frequency on December 4, 2010.
