Similarly, the Regional Programme broadcast much more light and dance music than its successor, the Home Service.
Each of these main stations was broadcast at approximately 1 kilowatt (kW): Each of these relay stations were broadcast at approximately 120 watts (W): On 21 August 1927, the BBC opened a high-power medium wave transmitter 5GB at its Daventry site to replace the existing local stations in the English Midlands, that allowed the experimental longwave transmitter 5XX to provide a service – which eventually came to be called the BBC National Programme from London and available to the majority of the population.
By combining the resources of the local stations into one regional station in each area with a basic sustaining service from London, the BBC hoped to increase programme quality whilst also centralising the management of the radio service known as the "regional scheme".
As the regional network expanded these transmissions were fully synchronised with those from Brookmans Park and several other frequencies initially: A relay station for Brookmans Park on 1402 kHz was due to open at Acle near Norwich in 1940, but construction was postponed by the outbreak of World War II.
Listeners were required to retune to a low-powered single-frequency network on 1474 kHz which did not offer any meaningful directional information to aircraft.
