RADIO listeners in the Crediton area could find it difficult to listen to their favourite radio stations in the future.

The government plans to enforce a switchover from FM to DAB digital radio for the majority of radio stations in the UK and if it goes ahead, Crediton residents and those across Mid Devon could find themselves unable to hear many radio stations on their existing receivers.

Local stations such as 107.3FM Radio Exe, which covers Crediton and Honiton, could come under threat.

Radio Exe has now joined a coalition of radio groups to protest about the proposed switchover.

Under the 2010 Digital Economy Act, the government is required to consider whether to set a radio switchover date by December 31, 2013.

Shortfalls in digital listening and DAB coverage mean that government criteria for setting a date will not be achieved this year.

Nevertheless, it is understood that the government is currently considering whether to confirm its intention to switch off the FM and AM signals of large local and national BBC and commercial stations.

Communications Minister Ed Vaizey MP is expected to provide an update on the government's digital radio plans at a speech arranged by Digital Radio UK on December 16.

Paul Nero, chief executive of Radio Exe, says: "Switching off FM would force a station like Radio Exe to divert money away from producing programmes and into the cost of transmitting the signal.

"Listeners in the region would be compelled to spend tens of thousands of pounds on new radios. And the cost of advertising would be forced up too.

"So all-in-all, it is a costly enterprise for a platform in which listeners have showed only modest interest over the past decade."

The groups speaking out about the risks of digital radio switchover are Anglian Radio, Celador Radio, CN Radio, Media Sound, Q Radio Network, Quidem, UKRD and UTV, as well as independent stations, including Radio Exe, Brighton's Juice 107.2, Radio Jackie and SIBC.

They collectively operate more than 80 commercial radio stations in the UK, covering locations ranging from Shetland to Cornwall and from Brighton to Derry and with a combined weekly audience of more than six million.

Fourteen years after the consumer launch of DAB, just 15 per cent of local radio listeners are currently using DAB digital radio – even though 90 per cent of the population listen to radio in some form every week (RAJAR Q3 2013).

In the latest RAJAR figures, the number of listeners to Radio Exe increased by almost 10 per cent, showing that tht FM as a platform is "alive and kicking".

Mr Nero says the enforced switchover poses a serious risk of listeners losing access to radio unless they buy new digital receivers.

He explained that Ofcom recently stated that there are 101 to 117 million radio sets in the UK market, of which 83 per cent are used at least weekly, but only 15 to 19 per cent are digital (Ofcom, Digital Radio Progress Report, September 2013).

"That means a large number of radios will be redundant if enforced switchover goes ahead," he added.

He explained that as many as 100 local commercial radio stations would either be left stranded on FM at switchover (possibly Radio Exe), or would be forced to reduce their local programming and take on higher transmission costs in moving to the DAB digital radio platform.

In Exeter, the cost of transmitting the service would at least double, potentially affecting the viability of a station like Radio Exe.

He added that agreement has not been reached between government and broadcasters on public funding for expanding local DAB coverage and even if this work goes ahead, it will benefit larger, local and regional services, rather than smaller local commercial stations, whilst placing an additional cost burden on licence fee payers.

The station while joining the campaign by 13 other commercial radio operators in the UK to protest about switchover, says it remains committed to technological progress for radio through increased quality, coverage and choice that will benefit listeners and the radio industry as a whole.

The group wishes to see platforms such as DAB continue to prosper, however the station and its colleagues in the coalition believe that consumers, not government, should determine whether and when there is a future switchover, with broadcasters retaining control in which platforms they invest.

Furthermore, the group say new policies should be devised to support valued local commercial radio stations.
