Austin is pretty far inland too. I'd imagine a Houston station would overpower radiation from THAT far away.

If you do take a road trip over here to Florida you can drive down U.S. 1 (also known as Useless-One) along The Florida Keys. Once you get down to the Lower Keys (approaching Key West) it may be possible to pick-up your favourite Austin Texas FM station ! There's lots of skipping going on across that great pond known as the Gulf Of Mexico, and stations all along the Gulf Coast from southeast Texas to the Florida Panhandle pop in and out when atmospheric conditions allow.

A few stations I've gotten in the keys include WOAI, WFLA, XEEW, XEFD, KODA, KTBZ, and others that escape me. None of them are consistant though. I usually get them for a couple minutes.
