This is probably K299BV, licensed to Houston, but current info on the FCC and Radio-Locator sites has the transmitter way out on I-10 just northwest of the Brazos River bridge. Supposedly only 10 watts on a 7 meter tower.
I heard the station with a choppy overall signal along Beltway 8 north of 290 during my morning and evening commutes today. At some places the signal was actually quite good, with fine audio quality. Seems to be running more power (or height) than claimed. I am over 30 miles from the purported transmitter site, and 10 watts on a 23 foot tower would not go that far with that kind of signal.
It is probably safe to assume that this is the same operation that was previously on 107.1, running the same sort of music. For several weeks after Christmas I had heard nothing but dead air being transmitted on 107.1 (although it was Stereo dead air) and now that signal has disappeared. The info for 107.1 also is gone from the FCC database.
Have yet to hear any kind of announcement on 107.7, although I didn't listen for very long.
This signal may cause problems for co-channel KLOT in Cat Spring, which went on the air several weeks ago.
