It's airing independently, Kev. All music, with two IDs, one at 5 before the hour and one two minutes after the hour. This was at a 10pm check. It simply IDs "Usted está escuchando Radio Aleluya, KMIC Houston 1590, escuche Radio Aleluya!"
Sounds like what you'd expect from a Windows media player feeding a transmitter. It plays a song, long pause, then on to another song. Pretty basic, I'm sure they're just testing out the rig.
It is what it is.
