In the mid-1970s, KWEN's effective radiated power was boosted to 100,000 watts, though the tower was still only 300 feet in height above average terrain.

It was also during the 1980s that KWEN got a boost in its antenna height, broadcasting from a tower more than 1,300 feet tall, with a signal stretching from the border of Kansas to the suburbs of Oklahoma City.

[9] KWEN aired a Contemporary Christian music format on its HD2 subchannel, branded as "Spirit 105.7", which was also simulcast on FM translator K289CC (105.7 MHz).

On March 16, 2023 radio news outlet RadioInsight reported that Screen Door Broadcasting had quietly flipped K289CC/95.5-HD2 to Oldies as “Groovy 105.7” earlier in the month.

The new station is focused on music from the 1960s and 1970s, bringing the format back to the Tulsa market for the first time since iHeartMedia had flipped K228BR to Classic Rock in 2018.
