From NW San Antonio:
Day: Semi-local Spanish-language Christian KTMR. City of license is Converse, to my NE, but the transmitter is actually about 40 miles SE near Stockdale.
Sunset: KWKH in Shreveport starts to appear. If I aim NE, KTMR is partially nulled and KWKH has a fairly good signal.
Night: KTMR doesn't usually sign off until 8 p.m. CT, and KWKH is heard not only in the partial null but underneath KTMR when I aim NW. Once KTMR is gone, KWKH is fairly strong. Sometimes there's a strange het that sounds like a train whistle that must have something to do with KWKH. I've heard it from various locations around town and only when KWKH is there. When aiming NW, I get a partial (and sometimes full) null of KWKH and occasionally hear brief weak signals from XECHAP in Chapingo and, more rarely, CKWX in Vancouver or KSDO in San Diego.
Sunrise: KTMR signs on a good ways before local sunrise. KWKH can still be heard weakly in its partial null but strengthens again and mixes in for a while when it goes to day pattern.
DX: One-time loggings include daytimers WLBA in Gainesville, GA, and WQFX in Gulfport, MS, both one night about a year ago when they were still on the air. Also, I logged KLEY in Wellington, KS, for the first time ever this past Sunday night. It had a decent signal at times in the NW partial null of KWKH, so it must've been on day power. I heard it again briefly last night, but it was very weak and surely back to night power.
Retro: Before they were retired, I heard XEYZ "La Poderosa" in Aguascalientes and XETOL "La Comadre" in Ixtlahuaca a few times each at night.
