The running order goes public.

The sheet on the transmitter-room wall is now on yours. Open the programme drawer and there's the whole week: every show, its hours in London time, and today's subjects — dated, the way a show sheet should be.

It stays honest by wire. The studio pushes every change straight to the site the moment it's made, and just past midnight the next day's sheet arrives — so the running order you're reading is always today's. A log doesn't guess.
