I'll give it a shot;
Texas A&M football and Basketball is heard on KFNC-FM 97.5 (and sometimes, allegedly, on 92.5). For the past several years, KLAT-AM carried their Spanish play by play,. But that seems to have ended this year. I'm not sure if the sale to LMN put a stop to that or if the local boosters just gave up (their Spanish broadcast can still be heard on a translator in College Station TX)
Texas Longhorn Football and Basketball is on KBME 790 AM. Their Spanish play by play has never been heard in Houston (or anywhere outside of Austin). I find it weird that the most liberal university put less effort than Texas A&M, a conservative university, into reaching Hispanic listeners across the state. At one point, Texas A&M Spanish broadcasts were heard in Houston, Dallas, San Antonio, RGV, and El Paso,
Cougar High Football and Basketball is on KPRC-AM 950.
LSU can sometimes be heard on one of iHeart's AM stations if there are no conflicting broadcasts (Astros take priority on 740, Rockets get 790/740, Longhorns on 790, and Coog High on 950).
Texas Tech has historically been in and out of the market. I could have sworn I heard one of their games on 610 earlier this season, but that could have been a Westwood One game. Back in the 2000s, they used to be on Univisions's KRTX-AM 980. Then after a while they found their way to KCOH-AM 1230 AM. Then they were on KKHT-FM. I don't think they have a full time affiliate this year.
Baylor Football is on KKHT-AM 1070.
Rice used to be on SportsMap 94.1. They were also heard, allegedly, on the 92.5 translator on some occasions. Unfortunately it seems that their radio broadcasts are limited to KTRU-LP 96.1 and to online only this season.
That's about everyone who has, or has had a radio presence in this market. TCU was briefly affiliated with Salem, but that went nowhere.
