I believe you may have simply not been able to receive the text from your location, jras. KTFM has had the data display for a little while now. I never paid much attention to it, heck...I don't even pay much attention to the scrolling text from the Houston stations (not while I'm trying to drive, lol!), but it's been there. Only reason I know this to be true is because my brother in law's daughter is an avid listener of theirs. As you can imagine, I much prefer what's airing on the old KTFM. Sure wish Houston's dial would've gotten more of a chance with Jack, but I digress.
That's a story for another topic...
