I think you have 2 different stations mashed together here. KHSE, licensed to Wylie (DFW area) features a South Asian format, with a directional signal shooting out towards the west, northwest, and northeast, giving it a clear daytime signal in the Metroplex, Sherman/Denison, Paris, Texas/Hugo, Oklahoma, and most of the Red River/Texoma area. You can even catch this one, with a fairly healthy daytime signal, up to the outskirts of OKC. It has a deep null towards the southeast, which is why I struggle to pull it in, here in Tyler. Likely the one you logged near Chicago, as they once in awhile forget to switch off the 1.5kW at night.
KSEV Tomball (Houston), on the other hand, is owned and operated by our lieutenant governor, Dan Patrick, and features a hard right conservative talk format. Much bigger daytime signal at 15kW, but sends a ton of that over the open waters of the Gulf. I've been on a cruise, with a portable receiver in years past, and heard it coming in clear down to the Yucatan. I've never heard it "forget to power down" and its night time signal barely covers even Houston. Not a whiff of it anywhere around this area of northeast Texas, day or night.
