Following the merger of the English-language service of Radio Luxembourg I with the new English-language service of Radio Luxembourg II on 208 metres medium wave, the station came to be known as Radio Luxembourg.
A British company, Radio Luxembourg (London) Ltd, controlled the programme content and sold the advertising time.

The station sign-on time at dusk varied between summer and winter to allow maximum benefit to be gained from a skywave propagation at night that covered the British Isles, although reception was strongest in northern England.
By restricting the service to night-time, the sales representatives were able to sell most of the available airtime both for spot commercials and for sponsored programmes.
One spot commercial that became burned into the minds of every Radio Luxembourg listener was for Horace Batchelor's "Infra-Draw Method" of winning money on football pools, turning the previously obscure Somerset town of "Keynsham, spelt K-E-Y-N-S-H-A-M" into a household name throughout the country.

Some programmes were live disc-jockey presentations by the team of "resident announcers" from the studios in Luxembourg City, while others were pre-recorded in the company's British studios at 38 Hertford Street, London W1.
This was never made clear to listeners, who were allowed to form the incorrect impression that all the presenters were broadcasting from the Grand Duchy or, alternatively, assume that all the programmes were recorded in London.

A conspiracy of silence operated throughout this period between sworn enemies Radio Luxembourg and the BBC, each of which never mentioned the existence of the other, although many famous names appeared on both, often almost simultaneously.
