BBC1 Scotland News Headlines, Weather, Scottish News & Closedown - 1983 

They should have made it clearer.

6:25 would have been the correct time, most episodes of the original Doctor Who run were 25 minutes.

Not in most of the UK.

Nope, Bob Logan, who was head of presentation at the time. He was also the husband of my 3rd year English teacher.

Yeah, that's the Independent Broadcasting Authority maintaining one of the transmitter aerials for ITV or Channel 4 (the IBA were the Government regulator over commercial TV and radio in the UK until 1990). The ITV (Grampian TV) 405-line TV service ended early from Rumster Forest in April 1983, so they were probably removing the redundant 405-line aerials at the time of this closedown, or the IBA were installing the Channel Four transmitting aerials prior to the transmitters themselves being installed, as Rumster Forest would begin transmitting C4 from February 1984. They might even have been doing both 405-line aerial removal and Channel Four aerial installation at the same time in one go.

BBC NI didn’t use the Northern Irish anthem either.
