This is a 24-hour commercial-free station that mostly airs on PBS affiliates and public access channels. A public-access college station airs it where I live, and I really enjoy having it on as background noise. They show all kinds of videos, mostly classical music, ballet, snippets from old movies, interviews with various artists, etc.
It is funded by the estate of a man who made his fortune from Adolph’s Meat Tenderizer.
If I’m up late ill watch but those bastards at KCET (the former PBS station in LA) have cut its hours. Its great background music.
This is my favorite CAS video.
p.s. Right now, I can’t get it at all, probably because we had a storm and it’s gone off before under those circumstances.
Thanks for reminding me of this. Eleven years ago I broke my ankle and after surgery I spent about two weeks staying with my then-bf’s mother at her independent living facility. We watched this channel most nights and loved it. I was 59, and she was about 90, but both of us had a good background in classical music, ballet, opera, etc., and this gave us a way of spending the evening together and having plenty to talk about. I didn’t know it was an actual TV station. I thought it was some closed-circuit recording provided by the Home. I just looked it up and it is broadcast by the local community college. Just tried to pick it up on my tv OTA (I have a Roku but no cable), but no luck. It’s a wonderful channel.
I used to watch it when I had C-Band satellite television.
I used to watch it, but Dish has cut it out of its lineup. I miss it.
I used to stream it on my Roku, until Nowhere Man’s Nowhere TV channel was removed.
Before that, I watched it on MCAT (Missoula Community Access Television) when it was on late at night.
I suppose I’ll try streaming it on my Odroid-XU4 using Kodi this evening.
The website itself also streams it.
And it’s back! 
A woman who used to go to a meetup I attend had wondered why that college had such big satellite dishes on the ceiling of their arts building; she knew there was a radio station out of there (they mostly play jazz) but not this TV station. She had worked for a while in the communications room of a cruise ship, so she knew a little about this kind of thing.
