BYU is on 89? I don't see it referenced on Lyngsat or Sathint... is it new?
Nope, it's their BYU Global channel, which is mostly their religious stuff. It's not the BYU variety channel, like 91w c-band. I'm not sure how long it's been there. It's harder to get in, but I got it here (mid-michigan) a couple months ago when I still had the dual ku/c-band lnbf installed.

I watch the one on C-band on 91w, that's the "BYU Variety" one, which is what you want. It's the ONLY FTA version of that channel. They have a lot of good shows, and frequently air Disney movies. The old-school ones from the '60's a such. So, if you can't pick it up, you can stream from their website I believe.

The KU one is their "global" channel, and nothing worth watching IMO.
