Norway first to start switching off FM radio


Norway will next week become the first nation to start switching off its FM radio network in a risky and unpopular leap to digital technology that will be closely watched by other countries considering whether to follow suit.



Critics say the government is rushing the move and fear many people may miss emergency alxs that until now have been broadcast via FM radio. Of particular concern are the 2m cars on Norway’s roads that are not equipped with digital audio broadcasting (DAB) receivers they say.


Sixty-six per cent of Norwegians oppose switching off FM 17% are in favour and the rest are undecided according to an opinion poll published by the daily Dagbladet last month.


Nevertheless parliament has given the final go-ahead for the move swayed by the fact that digital networks can carry more channels.


Switzerland plans a similar move from 2020 and Britain and Denmark are among those also considering such a switch. A smooth transition to DAB which is already beamed across Norway could encourage these countries to move ahead.


The shutdown of the FM (frequency modulation) network introduced in the 1950s will begin in the northern city of Bodø on 11 January. By the end of the year all national FM broadcasts will cease.

The main reason the governments want to switch from analogue to digital is not because there will be more channels but because digital uses less bandwidth they can sell off the freed up FM spectrum. There are two aspects to digital quality - true there is no hiss but it needs to compress the audio to achieve the bandwidth savings and with increased compression comes worse quality less bandwidth and lower costs. Also while the quality of analogue falls gracefully as the signal gets worse digital keeps going up to a point and then fails catastrophically.

they can sell off the freed up FM spectrum


to whom and for what?


It's not suitable for phone services - too low frequency.


Mootpoint Jones  GrahamPTebby 14h ago

Exactly! Thank you.


RegLaCrisp  Bosp 14h ago

You've asked this question many times. As far as I can see nobody has bothered to reply.


I hope you're not holding your breath? Given that almost every comment on here is negative it seems odd to me that nobody is prepared to come forth and argue their case.


That DAB is shite would be a good argument (if it is shite - I neither know nor care as the only time I ever listen to the radio is on the internet) but then one wonders why any government would even consider this change let alone actually go through with it. Norway and Switzerland are not backward countries - they must have good reasons ... mustn't they?


The article says; "For the same cost digital radio allows for eight times as many stations as FM and is said to have clearer sound and less hiss. The current system of parallel FM and digital networks each of which costs about 250m crowns saps investment in programmes." Everybody turning off would sap such investment too!


Norway is dramatically less densely populated than the UK and also suffers far more from extreme weather so the availability in cars must be an issue. Yet still the government is going ahead. They must think the good things outweigh the bad but they should try a little harder to explain their thinking.

My radio works fine. I do not want the unnecessary expense of "upgrading". Many people who are poor will be disenfranchised from listening to the radio if it goes purely digital. FM sounds great with a decent tuner.


savingUK  mojoangel 14h ago

Except (in the UK at least) they deliberately distort most FM stations using a special technique to make them sound louder. Not the case for classical stations though which may be more common in Norway?


Fanastril  savingUK 14h ago

There is only one classical station in Norway P1. The rest are from the 80s.


(注: AM就是指调幅制广播,也就是指中波及短波广播。这种无线电波的载频幅度,是随着调制的音频信号而变,优点是接收机的构造简单,能接收远距离的短波段广播及国内普遍采用的中波广播,每个电台的带宽是9KHz(双边带,音频带宽是4500Hz)。但是由于干扰信号主要是对无线电波的幅度起作用,所以抗干扰能力差、由于带宽较窄,音质较差,适合语音广播。

I wasn't aware of this. I always learn at least one fact a day from the comments pages

At least Britain will be reverting back to AM now that we have freed ourselves from all this FM and digital nonsense imposed by the EU loons.

至少英国会重新回到am  我们已经把自己从欧盟那些无赖编造的谎言中脱离出来

Can I borrow your shoehorn? Oh now I see it's one of those ironic shoehorns!

It's the long wave goodbye. I'll get my coat.

Your coat is already outside.

Even if you can get a decent signal (the higher broadcast frequency of DAB doesnt penetrate walls and buildings as well as the lower FM band)the life of batteries running a DAB can be measured in hours. I replace batteries in some of my FM radios at yearly intervals sometimes. Even using rechargeables this has surely got to be part of the consideration ?



Imagine junking all our existing radios to get onto a permanent upgrade treadmill of the "next format". Insane progress for progress' sake driven exclusively by DAB makers and government wanting to sell frequency blocks.


PS.(Digital Audio Broadcasting 数字式广播)

Democracy in action once again I see. I sympathise entirely with the majority in Norway who do not want to switch to digital radio.


The switch from analogue to digital TV stations here in the UK was one of the biggest rip-offs ever perpetrated on the unsuspecting public. There'll be hundred of channels we were told. Well yes and 90% of them serve up a woeful choice of programming not to mention the synchronized ad breaks we all have to suffer. The Treasury made a fortune from the VAT levied on all the new/converted equipment we had to invest in in order to view the digital content.


No doubt HMG are expecting the same when we all have to shell out for digital radios which if run on batteries cost a fortune. Then as mentioned in the article above there's the not-so-small matter of  having to change all our car radios which all work perfectly well at the moment thank you. Another money spinner for the Treasury.

毫无疑问英国政府也是这样想的,当我们全都必须换成数字广播在电池大花一笔, 正如文章中所提及的,把我们汽车上的那些工作正常的收音机全部换掉,这并不是一个小问题。这也是另一个给财政部送钱的圈套。

No doubt they'll try to sell the product by stating as before that there will be a swathe of new radio channels at our fingertips. Oh joy.


Haven't they heard the old adage: it's quality not quantity?


Evidently not...



exasperus  epidavros 13h ago

we have much much better reception


Lucky you!


a load more channels


of utter shit!


Matthew Cameron 14h ago

DAB is an already obsolete technology that was developed in the 1980's and doesn't even match early MP3. It is massively compressed unstable and massively energy inefficient.


It only has one advantage and that is that it uses less bandwidth giving the greedy government the opportunity to sell-off the remaining bandwidth to telecoms companies. This decision has NOTHING to do with offering an improved service.


In conclusion it's bollocks.


Bosp  Matthew Cameron 14h ago

giving the greedy government the opportunity to sell-off the remaining bandwidth to telecoms companies.




It's entirely the wrong bit of spectrum for that


marcus_rm  Bosp 14h ago

It frees up the entire FM spectrum to be sold off at a fat profit. That's what Matthew was getting at.


Remember when we moved from Analogue TV to Digital TV? it freed up the entire spectrum that old Analogue TV broadcast on and was sold off to the telcos for mobile data coverage.
