Norway is shutting off FM radio transmissions by 2017?
I never believe the “official” reason for anything like this. There is much more to the story than you’re being told.
Officially, the powers that be would have you believe FM is being done away with because digital is much cheaper to operate, and offers more options. Technically, this might be true, however the real reason FM is being shut off is much deeper than meets the eye.
Norway isn’t just “shutting off” FM becasue Digital radio is “better”. Norway is freeing up FM bands for OTHER uses coming soon, for sure the FM band won’t stay silent very long!
FM falls within the VHF (Very High Frequency) band. Norway is the location of EISCAT , the European VHF version of HAARP.
Worthy to note, as of January 2015, Norway is moving ahead with EISCAT 3D. To be completed by 2017. They are building FIVE DIFFERENT versions of a HAARP type array to work together with each other in conjuction using the VHF band!
Quote the literature on the EISCAT 3D project:

Thus it appears 233.0FM is going to be broadcasting LOUD AND CLEAR come 2017.
I can hear it now
“HOTT 233.0FM EISCAT – Burning up the airwaves with your favorite top 40 ionospheric “hits”!

In order to understand how close these frequencies overlap, FM Radio working in the 100MHz band… EISCAT working in 200MHz band, see the charts below which break down the RF (radio frequency) spectrum.
If you thought HAARP in Alaska was big, just wait until these EISCAT arrays are online.
Norway is building FIVE DIFFERENT arrays , 10,000 dipole elements per array!
Obviously this VHF European “HAARP” will be more like a rock band, than a single “HAARP” plucking its strings. Being able to cross waves to induce scalar energy at a distance is one of the obvious goals of this program.
262488154-EISCAT-3D-VHF-Antenna-prototype-DeliverableThis array will be able to cover the entire VHF spectrum. This means everyone else currently using VHF (FM) would be getting interference from the Tromsø Norway and Finland locations of these antenna arrays.
Thus they will shut off FM in 2017 when they start bringing these VHF arrays on line.

Article circulating in the news:
In 2017, Norway will be first country to shut down FM radio
http://www.theverge.com/2015/4/19/8453165/norway-end-fm-radio-2017
“Norway will shut down FM radio in the country beginning in 2017, Radio.no reports. The Norwegian Ministry of Culture finalized a shift date this week, making it the first country to do away with FM radio entirely. The country plans to transition to Digital Audio Broadcasting (DAB) as a national standard.
A statement released this week by the Ministry of Culture confirms a switch-off date that was proposed by the Norwegian government back in 2011. The government has concluded that the country is capable of meeting all the requirements necessary for a smooth transition to digital.
“Listeners will have access to more diverse and pluralistic radio-content, and enjoy better sound quality and new functionality,” Minister of Culture Thorhild Widvey said in a statement. “Digitization will also greatly improve the emergency preparedness system, facilitate increased competition and offer new opportunities for innovation and development.”
DAB currently offers 22 national channels as opposed to FM’s five, and has the capacity to host almost 20 more. The cost of transmitting radio channels through FM is also eight times higher than the cost of DAB transmission, the ministry reports.
DAB has been available in Norway since 1995. DAB+, an updated form of DAB, was made available in 2007. According to the Ministry of Culture, it will be up to radio broadcasters to choose between DAB and DAB+ transmissions, although it is likely that by 2017, most broadcasting in the country will be in DAB+.
Several other countries in Europe and Southeast Asia are also considering a national move to DAB, but no other country has confirmed a timeline, Radio.no reports.
Norway’s FM shutdown will begin on January 11th, 2017.

- Beam-formed data stored in ring buffer of relatively long duration (hours to days) in a manner which allows for users to access and copy selected intervals
- At least one set of time-integrated correlated data from each set of beamformed data calculated, and permanently stored in a Grid/Web accessible master archive
- At least one, and possibly several, analysed data sets permanently stored corresponding to each set of correlated data. These should be usable for quick-look applications and statistical studies
- Use of primary data products to derive routine value-added parameters (such as velocities, conductivities, currents, and heating rates) to be available together with the analysed data sets
- Additional data products also available from some (but not necessarily all) experiments usingtheEISCAT 3D radars
- Data on the properties of measured spectra (both ion-line and plasma line) comprising spectral power, numbers and locations of spectral peaks, asymmetries, spectral moments, and so on
- Data produced by interferometry applications (cross-phase, coherence and reconstructed visibility functions) stored in a ring buffer of sufficient duration
- Standard data products from the 3D system at each of the following levels
- EISCAT_3D Data Storage, Access and Visualisation Baseline
- Data Storage
- File-based and relational storage philosophies for data storage
- Storage systems to provide secure access for users and automated, secure remote backup, be Grid-compatible, and allow easy association between data and metadata
- Data Access
- Standard access applies to the majority of users, who wish to access the archived correlated and analysed data sets that EISCAT will store permanently, together with the appropriate metadata – accessible via the Web and ultimately via the Grid
- High-volume data access designed for interferometry data, beam-formed data and correlated data stored in medium term “ring buffer” storage at the pulse-to-pulse time resolution level
Access to data may be regulated according to “rules of the road” similar to those presently applied by the EISCAT Scientific Association.
- Data Visualisation
-
- Sample-level data
“Level meters” and similar utilities implemented; enabling the operator to probe the data flow rates the various antenna elements, to verify that the array is operating correctly - Beam-formed data
An approach similar to that used for the sample-level data implemented to enable scientists and operators to assess whether a particular beam-former is operating correctly and whether all of the input data streams from the antenna array are present - Correlated data
A capability provided to display data from multiple beams simultaneously, and to show detailed data from particular beams on request. The software will have the capacity to display data in the frequency domain (both ion line and plasma lines) and to show time histories of raw data - System Status Information
A user-friendly interface to provide operators and science users with various kinds of system information (transmitter power, system temperature, measurements of signal phase etc.) together with other “status” information required to establish that the various elements of system hardware are working correctly together.
A fault-diagnostic and corrective capability built into the interface. - Analysed data
A set of tools displaying the results of the initial analysis of each correlated data set, in a format suitable for verifying the correct operation of the system. Links between the visualisation utilities for correlated data, the analysed data, and system monitoring data to enable the presence of a fault in any one part of the system to be easily recognised elsewhere and its causes and consequences determined
