Both of those are very short-spaced. Also, the first one wouldn't even hypothetically put a city-data signal over Crystal Beach. I don't have time to run the map right now, but I doubt the second one would cover enough either.
I am surprised by the winning bid amount of this new station. But, I think, though, the way to think about it is that it is a "full-power" FM radio station that is technically in the Houston market. And it could be used, at least plausibly, to be the originating station for some non-fill-in translators that are owned by a different licensee.
