I guess WRNO has been here for a while, but I never caught it in Houston, and it seemed accidental tonight. I thought it was long defunct, but I'm glad to hear them.
I tuned in very briefly after seeing your post. It was some kind of religious program. Good, strong signal. It's possible I have tuned right past them previously, thinking it was WRMI or WWCR, as religious programming fills many of their time slots.
