During a period after the AM/FM pair was sold, 1230 (now KQUE) was used to continue the MOR standards format previously on their 102.9 counterpart during the ownership days of SFX Broadcasting Corporation which took over ABC Radio affiliate KNUZ "K-News" News/Opinion.
After the longtime Standards and Big Band format was folded in May 2001, KQUE became part of a quadcast with Rhythmic oldies-formatted KTJM until July 2001, along with 880 AM, and 103.3 FM.
Under Liberman's control, the station began as a simulcast partner of KTJM, as "La Raza", with a Regional Mexican format.
Liberman Broadcasting filed an application to sell KCOH to Pueblo de Galilea, LLC in April 2016.
On Friday October 15, 2016 Pueblo de Galilea completed the move of translator K223CW from George West, Texas to a tower located in north Houston.
KCOH officially relaunched as "1230 The Source" on April 15, 2019, bringing back many of the familiar shows and voices from the station's illustrious past.
