An announcement from ofcom UK :
Ofcom has today announced trials of a new technology that could provide small radio stations across the UK with an affordable way to broadcast on DAB digital radio.
If the trials are successful, UK radio listeners could benefit from more local and community radio stations on DAB. Currently, the cost of broadcasting on DAB is beyond the reach of many small radio stations.
But a new approach, pioneered by Ofcom engineer Rashid Mustapha, means that small scale radio stations could start broadcasting on DAB radio for a fraction of current costs.
The new approach is cheaper than current systems because it uses software freely available from opendigitalradio.org, rather than relying on often expensive hardware equipment. Known as ‘small scale DAB’, it is best suited for broadcasting to small geographic areas, ideal for community and local radio stations.
