The Antiques Roadshow (Series 32: 21 Leeds) from about 19 and a half minutes in, features some BBC equipment. Does anyone know what the units were? Nick Cutmore says "I think I read one as an MX/29/xx but we have no TI of that code. As such a code isn't an MXn/29/xx, it must be pretty early - early 1950s perhaps? When did the unit code sub classifications come in?"
The Antiques Roadshow (Series 32: 23 Hopetoun) features some papers from the BBC's first television broadcast in 1936. The engineering aspects are not mentioned except for the Baird/EMI tests, but the programme might interest visitors to this web site. The relevant part starts at 19 minutes and 17 seconds. It will be available throughout May. (My thanks to Nick Cutmore for telling me about this.)
