Unless you are talking about a different Gospel Music TV, it was on Sky Angel channel 9730 for many years until 6/2/05 (see http://ekb.dbstalk.com/247-5) This is when Hallmark Movie Channel took over. At the time, Sky Angel announced that some of the GMT programming would come to Angel 2 in the form of specials.
No, this is a diffrent channel. This is a fairly new channel. It's basically like MTV, but it's all different styles of Gospel music (rock,country,R&B, contemporary).
