KTWO 2 Casper (ABC) was uplinked, free-to-air until around '09 when Equity Broadcasting folded (they owned a bunch of low power and low-budget small town stations, including KTWO).
WSEE Erie (CBS) was also uplinked. But it wasn't the main Erie ch 35 feed. It was a special feed for the Caribbean - all local ads were replaced with PSAs/direct-response, all newscasts were replaced with paid programs, and they had "One Caribbean Weather", which included Joey Stevens and his sidekick, Bob the Parrot.

It's mostly network feeds now if you want the big dishes (all digital obviously). Some station have remote feeds for news, or live sports, but you won't see a local station with all the network/syndicated programming that often. Reason? Revenue. If KCNC (CBS 4 Denver, for example) was uplinked in the clear, people in the rural Midwest would view the commercials, therefore losing viewership and advertising dollars.
Canada was practically all in the clear from what I have read. If you went through the Anik satellite, you probably remember CBC's North feed. It was a national feed directed for northern Canada (in other words, the tundra). News was in English and in Inuktitat languages.
