This Media Network is concerned with closedowns rather than sign-ons as we delve back into the archives for a special documentary on offshore radio. Jonathan Marks, Diana Janssen, plus a host of other stars will be tracing one of the most important stages in the development of European Radio.

We now present, “30 years in 30 minutes”. That’s the voice of the late Paul Kaye, who 30 years ago today made the very last announcement on Radio London, or Big L. Radio London was the most successful of the radio stations which operated from ships and old army forts off the British coast between 1964 and 1967, and which had a major influence on the development of broadcasting in this part of Europe. A company called East Anglian Productions obtained a so-called Restricted Service Licence, which allowed them to operate the station for one month on mediumwave 1134kHz, using very low power - officially just one watt. Back in the 60’s, the original station operated with much higher power and covering a large part of the UK as well as the Benelux countries. To explain how it came to be on the air, we need to go back to Easter 1964.
