Channel 53, which had been a Spanish TV station being run from Oklahoma, has been off the air for months (though the signal, albeit black, was still on until recently), and they, along with sister station channel 49 (which had been running Retro Jams) are completely off the air. 49 has been off the air for about three weeks or more. Given that the owners of these stations didn't really give a damn about them, I would be surprised if they came back on the air.
