Ofcom is extending the nine month small scale DAB trials for a further two years.
Multiplexes are on-air in a number of areas: Bristol, Manchester, Portsmouth, London, Cambridge, Aldershot, Brighton & Hove, Norfolk, Glasgow and Birmingham.
Around 60 stations are part of the tests, which could possibly have faced being switched off if the nine-month trial was allowed to end.
The UK’s first experimental small scale DAB multiplex was set up in 2012. Ofcom engineer Rashid Mustapha was granted a test licence and installed a low power digital radio transmitter on a Brighton roof-top.
The test successfully delivered a reliable, high quality digital radio broadcast. The test transmission was an audio track of squawking seagulls.
The Department for Culture, Media and Sport is funding Ofcom’s work on how small stations could access DAB digital radio and the equipment available for these trials.
