In Houston, 101.5 is pretty well blank. Only station near Houston is KSTB Crystal Beach, TX @ 6kW from a sand dune on the Bolivar Peninsula. Unfortunately, the station has been off the air since Hurricane Ike hit here in '08, only setting up a temporary antenna to run the station from Crystal Beach at a reduced power twice since the station was literally washed away. Interestingly enough, there is a movement by a local broadcasting company based in Galveston, partnering with G.I.S.D. to purchase the station from Cumulus and return it to the air for service to Galveston itself. Based on reports down here, if Galvcomm can't make this work, KSTB will be lost forever as Cumulus will turn in the license.
In Bellville, a weak to fair signal from Austin's KROX Buda, TX appears most days. 12.5kW at 782 ft, airing Alternative as "101X".
