Michael Leapman’s ‘ Treachery? The Power Struggle at TV-am’ is an excellent account of the formation of TV-am and the troubles it faced in the first year.
Before breakfast TV came along, the ITV and C4 transmitters used to appear at about 8:30am, so there was obviously no Oracle teletext until then.
The BBC were often up from about 06:15 with OU progs starting at 06:40, so Ceefax was available.
I don't recall it was big deal either way ?
It's a long time ago but I can vaguely remember that teletext worked whilst the testcard was shown and (shortly?) after the closedown in the years before TV-AM.
Oracle local news pages during the time while TV-AM was broadcast were for London. Outside of the London ITV region you had to wait until the regional ITV company started up before the local news pages for your area were available.

Oracle will have worked all the time either your local ITV company or Tv-am were connected to the transmitters. When there was the IBA ETP1 test card, that was generated at the transmitters, so no Oracle. On C4 there were two ETP1s, one at Charlotte St, that had horizontal bars above and below the ident, and the version that had no bars, that was at the tx sites. Again Oracle only available during the former

Yes, teletext required a channel to be on air. I've got a Radio Times from 1982 where someone writes in to say that they were renting a teletext TV and had enjoyed being able to read the news on Ceefax at around 7am before they left the house, but it had now stopped. And the reason was because the Open University was on its break (as it was between October and January) and hence there were nothing on air to allow Ceefax to be broadcast.
