I've noticed that as well, last year I could only listen around Ingram Rd and as soon I drove down 410 towards Lackland the signal would become faint, and the farther you went it would disappear. I can hear it just fine by Lackland and can drive all the way to the Medical Center without any problems, but if I'm around 1-10 the signal picks up oldies. I've also driven down to the Southside by Pleasanton Rd and as soon as I get there the station flipped to some oldies. The signal seems like it's gotten stronger.
