2BE Belfast

2BE was the call sign of the first official radio station to broadcast in Northern Ireland. Operated by the British Broadcasting Company (later the British Broadcasting Corporation), it started transmissions from Belfast on 15 September 1924 using a wavelength of 435 m.

In 1936 the station was subsumed into the Northern Ireland Regional Programme, later to become the Northern Ireland Home Service, and then BBC Radio 4 Northern Ireland. 2BE's successor station today is BBC Radio Ulster.
