No, I can't scan anything in right now either, although my receiver has 5 or 6 transponders pre-programmed in that show good signal.
Yes, the Griz telecast usually powers up about 10-15 minutes before game time just like UND games, so just do blind scan a little before or after kickoff and it should come up. You might just get a black screen until the broadcast actually starts because in the past few years, you wouldn't see any commercials during Griz games on the KU feed, just a black screen. Montana State games power up just before game time as well, although I haven't seen the coordinates released yet for their games this year.
