Satellite TV Week had some programs listed on a "Recurring Feeds" section. I have the 9/21/86 edition right next to me, and a few programs listed were:
Donahue on W5-15, 9a/10a ET weekdays
Merv Griffin at 8p weeknights, T301-9 (Wold Communications)
PM Magazine at 9:10a weekdays, W5-18 (This was the Group W feed channel)
This Week in Baseball on T301-23, Thursday morning 1a ET and another feed at 8:15p ET. T301-23 was one of a few Wold Communications feed channels, another was T301-9.
PBS had three national feeds in 1986, Westar 4-15, 17 and 21. The schedules varied by time zone.
