Over here, I guess the problem is quite simple. TakeUp. Our DAB system broadcasts using 2 distinct bands. From memory, I think that the main audio frequencies are around 170MHZ, whilst the text-based services are broadcast up in EHF somewhere.
There is no doubt whatsoever that DAB is older technology than DAB+. Possibly the authorities over here might start to actually roll out those trial licenses sooner rather than later. In terms of community radio, the problem is quite simply one of cost. It’s often beyond the means of community organisations wishing to broadcast using terrestrial networks. Even good old-fashioned FM is incredibly expensive. It’s high time radio over here was opened up to the masses, as it is in other countries, possibly, including Australia. It’s also high time, in my opinion, that stations such as BBC national stations desisted from simulcasting. AM is hardly used any more for anything other than talk radio and oldies stations. Many of them wouldn’t be missed if they closed down the AM transmitters. Even FM is becoming less popular amongst listeners over here because, quite honestly, the cost of digital equipment has fallen through the floor. That has to be a good thing. As I understand it, the plan for the longer term over here is to remove all BBC and commercial stations from FM. FM will then be opened up to community stations, who can apply for much cheaper licenses than is currently the case. As an after-thought, it’s interesting to note that in the larger cities, London, Birmingham, Manchester and Liverpool, for example, there are still a number of one-man pirate stations on the air. So long as they cause no interference to commercial and government/BBC transmissions, they are usually tolerated because it’s just too expensive to go after them all. If one knows where to look, there are perfectly legal outlets where you can buy high quality transmitters, ranging from about 5MW to 1KW. Although it’s necessary to prove legality before the outlets are permitted to sell one of the higher powered transmitters. But I know of one person who has bought a 10Watt transmitter, which can use any frequency between 88 and 108 MHz. He says he’s been transmitting at the top of the broadcast band for some time now. Although I suspect he won’t be allowed to continue much longer as commercial stations are now utilising that part of the band as the band in larger cities in particular become more and more congested.
