I would be shocked if TNT was in the clear in Syracuse. In Rome on QAM I get the Syracuse NBC, ABC, CBS, PBS, Fox, My43, ion, and CW stations, plus WGN for whatever reason. I get a couple of the subchannels as well, but not all of them -- for instance no CoolTV. I get the Utica locals in analog, but no digital versions. All I have is the $8/month super-basic plan. I've considered getting rid of that since I can get all Syracuse and Utica channels OTA with just rabbit ears, but for now I'm willing to pay a few bucks for YNN, TBS, CKWS, and TWCS. I just wish I could get them in HD. (To answer your other question, I would guess it would take one more physical channel to carry those 4 chans on QAM)
As for WKTV, I set my dad up with an antenna this afternoon. The "news" was on at the time, and of course they were going on about TWC. I asked him if it was really worth the effort just to have to listen to that every newscast.
The WKTV issue is really getting old and WKTV is getting desperate. Just this morning I heard an ad for Dish Network (sourced from WKTV) chock full of misleading statements and outright lies. Advertisers are leaving WKTV and they need those cable numbers backs. I feel sorry for those who take their word and get duped into a two year contract without knowing the facts. The funny thing would be if Dish has a contract dispute with WKTV and then pull the channel from them later!
