Perhaps its from a webfeed then, or is actually MSNBC which is on more consistantly on that satellite. Or even CNBC. OP Please let us know!
Just been a power cut in hotel. NBC channel now showing a PC desktop, so guessing it's a web feed.
Try to get a station ID when its back up and working properly
Maybe someone can find that stream 
The 15w NBC feeds are never constant they're either on, off or showing random stuff. Not very appropriate for an hotel.
