To receive the radio

Your zone is theoretically covered, however you collect the radio badly

To solve the most frequent problems related to your installation

The reception of radio programs can often be improved by simple measurements, without one needing necessarily to resort to a top-of-the-range receiver. It is advisable to draw aside the most frequent causes of disturbances.

To regulate the station

On the radio operator receivers, there exist 4 types of antennas. According to your situation, and in particular if you live near or far from the transmitter to your radio, various actions on your antenna can enable you to improve the reception

  • Telegraphic antennas

Sometimes contrary to the generally accepted ideas, and in particular on the assumption that you live in the vicinity immediate of FM transmitters, it is advisable not to use the telegraphic antenna. If this one is delivered separately, it is advised in this case not to connect it. If it is fixed at the receiver, one will avoid - always in this case, to unroll it by folding up it as much as possible.

Conversely, when you live in edge of cover, far from the transmitter, it is necessary to use the antenna.

  • Telescopic aerials

When you live close to FM transmitters, it can be necessary not to deploy it, to even fold up it as much as possible. Conversely, if you are in limit of zone, it is necessary to deploy it to the maximum and to test several positions.

  • Individual or collective rooftop antennae

When a catch of mural FM, individual or collective antenna, is available in the housing or the place of listening, it is sometimes preferable to be connected to it.

On the assumption of a reception of the radio near FM transmitters, there exist attenuators, to place on the level of this catch antenna for the radio to optimize the reception of the FM signal.

  • Complementary antennas

They are antennas specific to the FM reception and bought separately. These antennas are particularly adapted when one is far from a site of emission.

To place its radio operator station at the good place

Beyond the advices above, when one lives close to FM transmitters, one will be able to improve the reception of the programs while seeking to move away the receivers from the windows, or by searching the place best adapted to the reception, which will be in particular function of the orientation of the place of listening.

The positioning of the radio within the place of listening even exerts an influence on the quality of reception, which can appreciably vary from one part to another, from one place to another of the part.

Moreover, proximity of the station with metal surfaces or electronic devices (computer, radiator, refrigerator, mobile phone…) is often disadvised when one seeks to improve an already delicate reception.

To pass from the stereo mode in mono mode

Since the receiver presents a ordering of the mono/stereo mode, this tip makes it possible in certain cases to improve comfort of listening.

 

Other causes to be considered

Jammings and electrical installations

The claims gone up on the level of the services of the Council relate to primarily jammings coming from other transmitters or the installations of reception not respecting the standards (case of FM). The other disturbances are caused by the electrical installations used in industrial environments or servants (case of AM).

With preventive measure, the Council intervenes within the framework as of qualified organizations of standardisation (International union of telecommunications, International conference of the administrations of the postal and telecommunications services, international electrotechnical Commission, special International committee of the radioelectric disturbances, European Institute of the standards of telecommunications), so that the disturbing effect of electrical equipment and electronic is limited, at the time of their design, with the values necessary to ensure a correct reception of the radio programs.

A breakdown of transmitter

To check near the neighbors if they are in the same case as you. Perhaps in the affirmative, that comes owing to the fact that the transmitter of which you depend is broken down, or temporarily stopped for a maintenance. You inform near the radio, by calling its national number:

Consult the directory of the operators

If the problems persist

If the disturbances persist despite everything these measurements, and if you receive the radio before, the Council can, thanks to its network of audio-visual technical attaches (ATA), established in area, to control the conditions of emission of the radios and to identify the sources of the problem.
