From NW San Antonio...
Day: Amidst slop from local 1130 KTMR, it's a weak-to-fair KTXW, 85 miles to the NE, with Christian talk.
Sunset: KTXW's signal improves, and KMOX starts to mix in. Sometimes daytimer KETU "La Diferente" in Catoosa will mix in. Aiming NW, I sometimes hear KCRN in Limon, CO, with Catholic programming before it signs off.
Night: KMOX dominates with a fairly good signal. KTMR signs off but hands over its splatter to 1130 KWKH in Shreveport. After dropping to night power, KTXW is only heard under KMOX on rare occasions. XEPOP "Cinco Radio" in Puebla is often heard under KMOX and can take over briefly during fades.
Sunrise: KTXW is back mixing with KMOX when it goes to day power, and so is KETU when it signs on. Occasionally I'll hear a weak KCRN at sign-on when aiming NW.
DX/Retro: I've heard WTWZ in Clinton, MS, once; it was during sunset a couple of years ago when the station had a bluegrass music format. Another one-time catch was XETQE in Tenosique, TB. It was around the same time period but at night and in the KMOX NW/SE null.
