The fact that there are still so many Unlicensed stations shows that government legislation, is still way behind modern day broadcasting requirements. Historically since 1969 people have been broadcasting music that they want to hear, from land based secret locations. Its about time in 2008 that OFCOM woke up and started offering affordable licences for small organisations that want to provide a service for their target audience, the current schemes for Analogue and Digital radio, only allow organisations with deep pockets to play at radio.
Local Radio Stations, that cover small areas often become automated or are run by volunteers, to remain on air due the expense of staff and licenses and lack of advertising revenue.
As long as it cost thousands ( sometimes millions) of pounds a year to bid in auctions for local radio licences.. pirates will remain, regardless of OFCOM or police action.
With Dab slowly loosing its broadcasters. Populating the bad with birdsong and various dross automated broadcasting. Local radio still is not available for those who want to broadcast but only have a minimal budget.
Chaining transmitters to railings on high buildings isnt working for local radio.. what will it take for the authorities to realise.. a more open system is needed.
