David Thorpe from Baldock Radio Station gave us an informative and engaging insight into the varied history of the Baldock Radio Station. Starting with the construction of the site from open farmland in 1929, we learned about the station's role in receiving early international telephone calls in the 1930s; radio tracking in World War II; ship-to-shore radio; TV detector vans and the essential monitoring of radio interference that can jeopardise important safety-of-life services.
