What makes you think there were many stations that must have been uplinking?

I think you may be laboring under the false assumption that affiliates were sharing packages with other affiliates. Its much too late now to tell but I'd bet that wasn't happening (unless the stations had joint ownership in which case they may have had their own methods of sharing packages). Microwave was/is a pretty popular alternative and it didn't/doesn't require renting satellite time.+harshness Sometimes, it will be but some certain news stories will be previewed on there before they go on the local affiliate's newscasts.
How often did that happen? Once a week? Once a month? Never?+harshness Whenever there's a news event or when news breaks there's often a need to uplink via satellite newstrucks.
Network feeds are downlinks. It is all about the direction that the feed is traveling. If there are 200 or so affiliate stations, maybe only one or two a day were uplinking stories to the mother ship for the national news. I would also point out that feeds were delivered on a schedule and not interactively.+harshness so what were the ABC news feeds being used for at the time?
I don't recall much in the way of regional news packages from 20 years ago but I'm in a geographically large DMA. In tightly clustered DMAs, I imagine that regional content was probably transported on video tape or via microwave.+harshness Well as for the stories being uplinked for the national news weren't there any affiliate or regional feeds?
I've always excepted the superstations. Two out of more than two hundred certainly doesn't rise to the rank of notable.+harshness well other than that, as mentioned earlier WSB Atlanta and flagship affiliate KABC Los Angeles were also being uplinked on Primestar (GE-2 Ku (W7)).
Those were the Canadian DBS services (ExpressVu and Starchoice), Anik E2 Ku (A2) could only be accessible in the Northern part of the United States, It was for Canadian programming and channels which were superior to American TV (CBC, CTV, Global, CityTV, YTV, History Television, TSN, Family Channel Canada, TreehouseTV, MuchMusic, Superchannel, Teletoon, The Movie Network, Bravo Canada, Showcase, CBC Newsworld etc...).DBS uplinks weren't accessible to viewers or the networks as they were the property of DIRECTV and Dish Network so I'm not sure how this qualifies as useful information.
Translators have rarely (if ever) employed satellite to get their signal out. Before using high speed data lines, they typically used terrestrial connections such as antennas on tall hills or microwave.Well I also forgot to point out that WMUR's newscasts were also being simulcast on W27BL/W16BC (WMUR-LP) in Berlin and Littleton, NH respectively, both of which were low-powered Fox stations.
Well for ABC and other networks, the news feeds from affiliates generally depended on the time of day, as I have mentioned earlier.I'm not sure how this supports your position that Ku band played a significant part in local TV thirty years ago.
