Channel 4 pre-1993 regional opt outs

Probably a slip of the keyboard, but it was Graham Rodgers not Roberts - spot of inter-company confusion there! BTW, the Yorkshire Post used to print schedules for TTT, GRA and BOR, while the West Yorkshire-centric Evening Post had the first two only.

I also managed to get a very clear TVS signal on the night of the 1990 Telethon, which I also received on an overnight (with Graham Roberts announcing -- "Late Night Late" was it? -- and I seem to recall him mentioning that people across England were picking the signal up). Again there were no repeats of that.

Belmont and Emley Moor had separate ITV feeds, split ad spots, 7 minutes of Belmont Calendar and in the '70s the " Belmont Weather Forcast " .... all the way from the Agricultural Hall in Naaridge.

Did C4 ('80s) have split spots between Emley and Belmont? I doubt it, although Belmont was fed by GPO/BT microwave via Farley (**) one assumes that there was only ever one C4 output from YTV Kirkstall Road.

(**) How sure am I about this? Only 50% ITV was always microwave into Belmont, originally ITA RBL via Massingam and Winceby, but then BT from Leeds/Tinshill via an intermediate point to Farley nr Ollerton and then into Belmont. BBC was RBR Emley, but ISTR that changed at some point to give Belmont a cleaner feed free of co-channel interference. Always assumed that C4 was always fed to Belmont via GPO/BT microwave along the same route as ITV, but of-course it may have been RBR Emley?

A while back I posed a question as to how ITV's TCF (derived from Emley) got to Belmont. Someone who knows about these things pointed out that ITV was dual fed out of Leeds, to Emley Moor, where the Belmont feed returned to Tinshill and hence on to Belmont. Perhaps the same was true of C4?

The question about TCF is interesting, I assumed that would have originated at Belmont itself, albeit controlled from Emley ROC.

I don't think Belmont had a fully equipped control room (with its own slide scanner ?) It did have a control room though, an ex boss of mine was the duty engineer there the evening Emley collapsed. He was told to grab all the staff, and hot-foot it out of there, as a precaution.

It was (as you said) a manned station originally. There was a test card, "D" with "ITA Belmont Ch 7" on B7. When E25 opened, it was "IBA Anglia Television", presumably this came from the colour control room at Mendlesham, microwave (BT or IBA?) to Tacolneston (**), then off-air and RBL to Belmont. There was an announcement (or a slide, I can't remember) that said something to the effect that all the frequency gratings on B7 were nonsense because they were broadcasting a converted TCF.

During the times when the local ITV companies sold C4 airtime, did any of them insert trailers for their own local programmes, on their own channels? I'm not aware of STV ever putting a trailer for Scotsport on C4, so perhaps it didn't happen on a UK basis. Or did it happen elsewhere?

Beyond the opt out local pres announcements that Thames and LWT did, discussed up thread, I don't think so ?

but you generally only had at most one programme trailer either side of a commercial break back then (on ITV and C4) so additional ones may have been seen as overkill.

By the 1990s multiple promos either side of a break were becoming common on a lot of ITV stations. TT (which I assume you're basing your observation on) were an outlier in continuing to only put out a single promo and padding out with long IVC/menu pieces from the announcer.
