From NW San Antonio:
Day: Nothing
Night: When propagation is favorable, most commonly in fall/winter, I'll hear a weak but sometimes readable CHHA in Toronto. Also when conditions are good, aiming NW I'll hear a TIS, "K-YAK," in Indianola Beach Park, which is about halfway between Corpus Christi and Houston. It broadcasts info about wildlife in the area and the history of Indianola, as well as fishing tips.
On rare occasions when propagation is exceptionally good, I'll hear WPEZ840, a TIS in Buchanan Dam, NW of Austin, which relays an Austin NOAA weather station.
DX/Retro: Every now and then I used to catch XEUACH, Radio Chapingo, before it moved to 1130 a couple of years ago; it seemed to have limited broadcast hours. Also, on my very sensitive radios I regularly heard a weak Caribbean Beacon in Anguilla before it went off the air.
In addition, at sunrise I used to hear a TIS to my NW/SE that I was never able to identify because the signal was faint and noisy. There were some highway references, but those roads covered a fair distance in Texas.
