I live on the north side of town, near I-30. I even pass by the central office (it’s on Small St near US-80). A source who works for SWB confirmed that the CO has a 1A switch. It’s electronic (this is why it’s still around), but switches an analogue signal.
She a wee bit further north . . . around Avenue K & 360 off of it. Good ole Highway 80 . . . I remember use to getting caught in the train traffic near the Six Flags Mall and Southwest Pkwy! I still return to visit but live hundreds of miles away.
