Just one favorite channel? Such a tough choice.
While I really enjoy a lot of channels (especially RTN, Russia Today, WRN English, UWTV, KEXP, and all the PBS feeds), I guess what I value most is that bits arriving from space are "cooler" than terrestrial bits. They have cool Faraday rotation gyration action and even when the picture is exactly the same, it's better from satellite.
Eh, by number of hours listened I think the service I'd miss is WRN English, so I guess that's my favorite. Even though it's "only" radio, it's about the broadest single source of news I have found anywhere. And you can do other things while listening to radio that a picture would distract you from, so for a sheer "hours" point of view, I'd rather keep my radio:TV ratio above 2:1.
