DRM will be part of a big anniversary on a small island in the Atlantic Ocean. On 28th of August at 1155 GMT Babcock International will ensure a special BBC digital transmission on 21715 kHz from the BBC Atlantic Relay station, marking the fiftieth anniversary of the BBC’s first short-wave radio broadcast from Ascension Island.

Since 1966, the Atlantic Relay station has broadcast BBC World Service programmes to Africa and South America, and to this day, continues to broadcast over 250 programme hours every week to East and West Africa in English, French, Hausa and Somali.

The two hour-transmission on 21715 kHz will start with the old, special sound of Bow Church Bell in east London, the sound of which, even if in DRM this time,  will remind older listeners of the BBC broadcasts of many decades ago. The 21-hour transmission will be the regular BBC programmes for West and South Africa and will end at 1400.

DRM – Digital Radio Mondiale, is an international digital radio standard designed by broadcasters, for broadcasters, in co-operation with transmitter and receiver manufacturers. DRM is a high quality digital replacement for analogue radio broadcasting in the AM and FM bands.

This special transmission will be sent with greetings from Ascension Island’s BBC and Babcock International staff and visitors, who will be celebrating half a century of sterling broadcasting on August 28th.
