How to receive France Inter even after the stop of its diffusion in long waves?

This decision of Radio France was made in agreement with the Government.

The CSA is attentive with the concerns of the listeners who anticipate problems of reception. If you did not have the occasion yet of it, we invite you to consult My Radio FM or the tool placed at the disposal by Radio France to identify the frequencies which you are likely to receive. If you test the frequencies indicated by these tools, do not forget to deploy the antenna of your FM receiver and to test several orientations of this antenna, or to use your FM antenna of roof if it exists.

In addition, you are perhaps able to receive France Inter by other networks that FM: France Inter can be listened live on Internet and figure often in the television offers by satellite, cable or in the multiservices offers (offers known as “triples play”) Internet access providers. The listening of a service of radio by these networks necessarily does not answer the whole of the uses generally observed in France (listening at the house, of mobility, on the workplace…).

For any complementary question about this subject, you can consult the website of Radio France (, which also set up a specific call number, 01 56 40 40 50, that you can call of the Monday to Friday of 8:30 to 19:30.

Why isn't there in France of radio diffused on the DVB?

You wonder about the absence of radios on the DVB. Here some brief replies:


  • the standards used for the DVB and the regulation framework allow indeed the diffusion of radios (in digital mode) on the DVB.


  • For as much, no radio is actually diffused in DVB and SCUMS did not launch appeals for the candidatures so that radios are diffused on the DVB:
  1. - the law of September 30th, 1986 relating to the freedom of communication, that the CSA implements, provides that the CSA allots a significant share of the frequency band 174-225 MHz to the diffusion in digital mode by terrestrial hertzian way of the radios. Since the passage to the digital whole of television, this waveband is not used any more for the diffusion of television services in France. SCUMS thus privilege the waveband 174-225 MHz for the diffusion of radios in digital mode compared to that currently used by the DVB and launched 3 appeals for the candidatures which related to the zones of Paris, Marseilles, Nice, Lille, Lyon, Strasbourg, Rouen and Nantes. The diffusion is already effective in Paris, Marseilles and Nice.


  1. - The waveband used for the diffusion of television is the object of a reduction (transfer of band 700 MHz to the mobile operators of electronic communications) and the induced operations of refitting must be completed in June 2019. This reduction of approximately a constrained third of the waveband mechanically more strongly the spectrum in a context of maintenance amongst televisual services and of the quality of the diffusion. The CSA thus chose until now to maintain the attribution of these bands to the services of television, the radio operator profiting mainly from two other frequency bands, the above mentioned band 174-225 MHz and the band FM.


  1. - This choice of SCUMS not to put radios in DVB rests not only on legal but such economic and technical considerations. Taking into consideration European country other, the French televisual landscape until 2005 was more restricted whereas the French radiophonic landscape was on average developed more. The French radiophonic landscape consists of radios with national vocation and local radios. The DVB could meet only partially the needs for certain radios (the radios with national vocation) but cannot meet the needs for the local radios. In addition, the technical choices of the DVB currently in force do not allow a good reception of mobility but the reception of the radio mobility is a prerequisite for the radio: the reception of mobility corresponds to approximately 30% of the volume of the listening of the radio according to Médiamétrie. Radios are diffused by satellite or are included in the offers known as triples play (Internet access, fixed telephony and television) of the Internet access providers. For as much, the listening of the radio thanks to these modes of diffusion remains a marginal use. Lastly, no radio appeared near SCUMS to be diffused on the DVB.

Where to get to me a list of the radios diffused in my area?

You can online consult the list of the radio frequencies put on this site which will give you, by department, by station or frequency, the list of the radios, their zone of diffusion and their frequency. 

In addition, the CSA gives you in his directory of the operators the contact of the principal stations of radio.

Why certain radios aren't they diffused everywhere in France?

There exists in France, on the one hand, of the public radios and, on the other hand, several categories of private radios, some with local or regional vocation, others with national vocation. The question of their diffusion about the whole of the territory thus arises only for the seconds.
The radios are diffused starting from transmitters installed in zones of territory. The Radio France company, public company, have a priority right for obtaining of frequencies on the unit of the zones of the territory. It distributes these frequencies with its liking between its various stations (France Inter, France Info, Mouv', France Musique, France Culture, etc). The private radios, as for them, must, to be present in a zone, to obtain from the CSA an authorization of diffusion.
To obtain an authorization of diffusion, the radio must stand as candidate at the time when are launched, by the CSA, of the calls to candidatures. Those are decided when frequencies are vacant or that new frequencies are identified on one or more zones. The radios can then, if they wish to emit in the zone (S) concerned (S), submit a file to the CSA which will examine it according to various criteria, among which:
 - warranty of the pluralist character of the expression of the currents of thought and opinion, the honesty of information and its independence with regard to the economic interests of the shareholders,
 - the experience gained by the candidate in activities of communication,
 - financing and prospects for exploitation of the radio,
 - interest of the project for the public, taking into consideration pluralism of the sociocultural currents of expression,
 - the contribution of the radio to the production of programs carried out locally,
 - the diversity of the operators and need for avoiding the dominant position abuses as well as the practices blocking the free exercise of competition.
 Once the selected radios, it will be necessary for them to sign a convention with the CSA to obtain an authorization of diffusion. 

If a radio is not present on all the French territory, that can thus hold with one or more factors:
 - this radio is a station local or regional and was not conceived to have a national diffusion;
 - this radio, although to national vocation, candidate did not go, for reasons who belong to him, at the time of the last calls to candidatures launched by the CSA in the zones where it is absent;
 - the radio stood as candidate well but was not selected at the time as of last calls for candidate within sight of one or several of the criteria given above.
Generally, it should be known that the number of frequencies FM is limited, which does not make it possible to the CSA to fully give satisfaction at the requests of each operator. Moreover, the occasions to deliver new authorizations are rare insofar as the existing frequencies are allotted for one five years renewable duration twice.
In addition, all the zones do not have the same number of frequencies, because of their geographical characteristics in particular: in the border areas, for example, the CSA must take care that no granted frequency can scramble the frequencies used by the close country. In a mountain region, the frequencies of less are carried that in the zones of plain, because of the relief which obstructs the wave propagation.

Why large radios like Europe 1 and RTL aren't diffused in FM everywhere in France?

Since the opening of the FM band to the private radios there is more than thirty years, the attribution of the frequencies to the operators was carried out zone by zone, as calls for candidate launched by the successive regulatory authorities. In this respect, it is advisable to recall that only present at the origin on the long waves with the national radio, the great historical stations such as RTL, RMC and Europe 1 did not express an immediate interest for the diffusion of their program in frequency modulation and obtained their first authorizations in 1986, this delay which could not have been caught up with thereafter.
In addition, the CSA was brought, just like the CNCL which had preceded it, to select the operators according to the number of frequencies available and while respecting, like invites there the law, a necessary balance between the various categories of stations (radios associative or commercial, local, regional, national, sets of themes or general practitioners, etc). It thus obviously, because of the very a large number of requests, could not allot a frequency to each radio candidate in a given zone.
Before launching the last appeals for candidatures, the CSA sought the best way of optimizing the resource available to allow the diffusion of the greatest possible number of stations per zone. However, even if a considerable profit of frequencies could be obtained, no station, so important is it, could not claim to be present on the totality of the territory.

Why the large radios have don't the same frequency in their various zones of diffusion?

The attribution of the frequencies FM to the operators was carried out zone by zone with the passing of years, within the framework of the successive appeals for candidatures launched by the CSA. Each zone has a particular number of frequencies, which varies according to its geographical characteristics and in particular relief, but also of the frequencies already used in the close zones. Thus, all the spectrum of the FM band is not possible to use in the whole of the zones.

Moreover, it is particularly difficult to use a single frequency for a radio on the whole of the territory, because the resumption of the same frequency on transmitters installed with too brought closer intervals generates important phenomena of jamming which do not make it possible to ensure a sufficient comfort of listening. To retain the principle of a single frequency would result thus in to decrease the number of transmitters possible to install and, consequently, the cover of the territory.

Today, some stations with national vocation lay out however, in a certain number of regions sufficiently distant from/to each other, of an identical frequency. Nevertheless, it is impossible to allot this one everywhere and in particular in many border zones because it is not rare that the aforementioned frequency is already in service in the adjoining countries.

Only one case of figure derogates from this essential rule of the planning of the frequencies: radios of motorways which lay out on the unit of the territory of frequency 107.7 MHz, but with synchronized transmitters (technology expensive and difficult to implement on very large surfaces) which, although neighbors from/to each other, but with a cover limited to a band along the layout of the motorways, do not scramble themselves between them.

When will the next call for candidate for the authorization of FM radios take place in my area?

It is the territorial committee of audio-visual (CTA) of which you depend who can give you information. Do not hesitate to contact it.

Consult the list of the territorial committees of the audio-visual one. 

Which is the procedure to be followed to diffuse radios in a public place, a trade for example?

The CSA does not have competence in this field. It would be necessary to address to you to the SACEM (Company of the authors, composers and editors of music).

Which are the frequencies of the principal radios in long waves?

 - France Inter - 162 Khz
 - Europe 1 - 183 Khz
 - RTL - 234 Khz
 - RMC - 216 Khz.
