I was listening to KSHN today as I was driving home (even though I'm way out of its coverage area in Houston, my vehicle receives it fairly decently most of the time). As I was driving up Holcombe, for about half a mile, some Tejano station overrode the signal. It had an announcer, so I don't think it was a pirate or a Part 15, but I wasn't able to catch an ID. I'm just curious about where this might have come from.
