Licensed to Springhill, Louisiana, United States, it serves areas such as Texarkana, Magnolia, Haynesville, Cotton Valley, and Plain Dealing.
The station was bought in December 2008 by Leon Hunt (owner of KJVC in Mansfield, Louisiana) and continued to broadcast country music.
1460 was the granted the KTKC calls, dropping the long held KBSF, requiring this facility to add the -FM suffix.
Houston Christian Broadcasters acquired KTKC-FM and sister station KTKC from Leon Hunt effective May 31, 2018, at a purchase price of $200,000.
The new owners changed the station's call sign to KSPH that same day, and began simulcasting programming from the primary KHCB-FM in the Houston, Texas area as a part of the KHCB Radio Network.
