For anyone who's interested, here's a post with a short video showing how Small Scale DAB works using open source software and software defined radio. It's intended to be suitable for anyone, but includes some detail for fellow geeks!

It is a pity the old DRDB did not see a potential of hanging on to the L-Band frequencies because L-Band propagation characteristics were perhaps more suitable for community radio coverage! The caretaker of these small coverage multiplexes could have been local authorities. That was then, this is now, I suppose.
Thanks for the video demonstration...

It's all about money Willie. Those L band frequencies are going to be auctioned for mobile data. In the German auction they are currently rocketing in value - €119million and counting. http://www.telecompaper.com/news/german-auction-yield-at-eur-24-bln-after-1st-week--1085675

L Band's already been auctioned off. Qualcomm paid Ofcom £8.3m for it in 2008.

Of course Matt - why did I forget that?! I wouldn't be surprised if QC flogged it off soon though - would make most sense for O2 in UK who are spectrum-poor compared to their rivals after a terrible mauling in the 4G auctions.

I hear, incidentally, that we can expect announcements this week in terms of who gets those trial DAB licences.

Well it seems in Germany the L band 1500MHz frequencies went for €320million or so. I can't see any regulator spurning that amount of money to let DAB radio use it.

Given that there isn't a single country using L-band for DAB any more (as far as I am aware), and that most DAB sets don't actually receive it, I think it is a foregone conclusion that broadcast radio has lost this spectrum.
