Oddly enough, I too would love to find that feed for Channel One. I remember that from 7-8 years ago. We did "live" news announcements on the tv system every morning right after the Channel One box finished running the taped feed. That thing was a HUGE silver box about the size of a small console tv. Had a VCR built-in, with a SAT IN and a MAIN TRUNK feed that connected out to the school. There was a externel feed switch on the side where would connect in our editing/camera equipment to do our "news" in the morning. I only remember this so vividly because even 10 years ago in high school I was considered a nerd and was always on the "news" camera crew. : )
On the back of the school we had what I remember was a Channel Master 1.2m KU and we also had a C Band which the tech department used for the old NASA analog feed which they would turn on for the launches. Very cool.
I am about to get my Primestar hooked up today to the new pole I just put in the yard (pictures coming) and I am certainly going to be looking for that feed if it is clear. OP, please keep us updated if you find it first, and if it is I.T.C on Lyngsat. Thanks for jogging my memory! : )
