KSTB (101.5 FM) was a radio station broadcasting a country music format.
After Hurricane Ike, Cumulus had filed for permission for the station to cease operations and stated that it had no specific plans on whether it will attempt to rebuild the station given the scope of the disaster and the poor economic conditions, according to the FCC filing.
Before KSTB broadcast on the 101.5 frequency, its dial position was 104.9 FM with the call sign KRTX, and was licensed to Galveston.
The satellite content would continue through the change to KSTB, which began broadcasting in the summer of 1995.
In August 2010, KSTB briefly returned to the airwaves as "Energy", playing music from the 1990s.
