From NW San Antonio:
Day: Just local 1100 KDRY's splatter.
Sunset: KVTT in Mineral Wells, TX, is heard if I aim the radio N-NE, which nulls the splatter a bit. KFAB eventually starts mixing in, as does XERED in Mexico City.
Night: It's a mix of KFAB and XERED with the splatter somewhat reduced. KFAB is the most dominant. Often I can hear KEJL "Eagle 100.5" in Humble, NM, with a weak signal before it signs off when I aim W-NW. XEWR in Ciudad Juárez can sometimes be heard with Spanish-language Catholic programming in that same direction.
Sunrise: When KVTT signs on for the day, it mixes in with KFAB and XERED and makes a mess. Aiming W-NW, I can hear a weak KEJL when it comes back on the air (as well as more KDRY splatter). Occasionally I'll hear XEWR and later KTEK "Relevant Radio" in Alvin, TX, when it signs on.
DX/Retro: I've heard KWVE in Pasadena just once, back when it was KRDC "Radio Disney Country." Other one-time loggings include KTTP in Pineville, LA, about nine years ago when it was still on one night, and the now-silent WTOF in Bay Minette, AL, at sunrise. Also, I heard XEOQ "Notigape" in Rio Bravo a few times at sunrise before it was retired. On rare occasions I'll hear a faint WBT at night and at sunrise.
