It’s 100 years since public service broadcasting got under way with the BBC’s transmissions from 2LO in London. Prof. Tom Stevenson tells the story of early radio with its powerful transmitters sending signals for reception on crystal sets with cat’s whiskers and early thermionic valve wireless sets.

He highlights examples of early radios which can be seen on display at the Orkney Wireless Museum in Kirkwall and the Museum of Communication in Burntisland, Fife.

This event will also be livestreamed.
