In the Superstar Magazine from July 1998, on Ku-band side of the chart it lists SBS4 for NBC feeds (though it was one of the inclined Ku birds at the time) from 1-10 it lists NBC/Occasional Video
B4-2: NBC (Occasional)
B4-6: NBC (Occasional)
and it also lists NBC Newsfeeds on GSTAR3
R3-3: NBC Newsfeeds
R3-4: NBC Newsfeeds
R3-6: NBC Newsfeeds
R3-7: NBC Newsfeeds
R3-9: NBC Newsfeeds
R3-11: NBC Newsfeeds
Though Ku-band was more of an occasional video bird, the rest of Ku mostly consists of Conus, sports and news feeds. Satcom K2 isn't in the Superstar Ku chart since it was one of the more inclined Ku birds at the time (along with SBS4).
