I think they are nuts. I don't see how FM can cover into fiords as it is - seems to me that each fiord would need at least a translator to cover people living it in. Then to switch to something as problematic as digital would be mighty foolish.
According to what I've read, Norway has a network of over 1,700 repeaters for their national networks — many of which only cover small isolated populations at the bottom of the fjords — and they are slowly coming to the end of their useful life. The cost to refresh and renew all those broadcasts is estimated to cost more than to finish the national DAB+ rollout, so they're going that route instead. DAB in Norway is in the VHF band around 200 MHz and allegedly has better coverage from fewer transmitters since the reflected signals can be handled by the DAB radio's processor, much in the way (in theory) HD eliminates picket fencing and reflection issues on our FM broadcasts.
FM broadcasting won't really come to an end in Norway, as there will still be some low powered services available as a fill-in, as well as community broadcasters and the like. But the national and regional services which are already on DAB will just cease to exist in analog.
I know that asking people to read the comments section of any website is kind of crazy, but the dyed in the wool radio people on this site would do well to read the comments on this subject as reported by tech site
Ars Technica. It's very much an eye-opening view into what the 'real world' of the technological elite think of broadcasting in the 21st Century. These people may not be the majority
now, but their kind is growing while our radio-friendly kind is shrinking.
Here's what I took away from the comments, representing a global audience with a US-heavy presence: DAB and DAB+ have their share of detractors and fans, while not a single person has said anything nice about HD radio. In fact, out of 130+ posts so far, only two people have acknowledged listening to FM radio of ANY kind, and then only for sports play-by-play. The overall take on American commercial radio is so overwhelmingly negative that it's shocking, IMHO. And while these people are not representative of the majority of US or global listeners, they will be one day as technology becomes more accessible and cheaper. Radio has done jack squat to lure these people back into the fold, and they are never coming back. And why should they, when "online" or their personal music collections offer them so much more.
