![]() You’d have to get your radio closer to a microwave oven for example, and observe whether or not the buzzing sound increases as you get closer to it. Since this piece is focused on how to improve AM radio reception at home, we’ve narrowed down the list of domestic appliances known to produce radio signals that may interfere with radio reception.Ĭonfirming that one or more of these appliances is the cause of interference is much easier if you have a portable radio. Sorting this out would mean switching the appliance off, moving it, or moving the radio further away from the source of interference. ![]() This is most likely to be an appliance that’s not too far from where the radio sits. Last but not least we have the buzzing sound, which is normally a sign of electrical interference. Fortunately, dealing with it requires a very simple fix.Īll you’d need to do is purchase an attenuator, and have it plugged between the aerial and the aerial socket. It is as a result of the radio signal being overloaded. This type of interference normally occurs when your home or workplace is in very close proximity to the transmitter. This antenna will only pick up direct signals from the transmitter, and avoid any reflected signals that may be bouncing off nearby landscape features. If this sounds like your ailment, you might want to consider installing a rooftop antenna. This is usually the result of the cross-interference between signals getting reflected off tall buildings or hills, and direct signals. This is characterized by ‘s’ and ‘z’ sounds being distorted to ‘shhhh’, and comes about when the signal being transmitted to the listeners receiver uses more than one path. To deal with this accordingly, you might have to invest in an outdoor antenna, or place your radio closer to the window. This may be the result of being too far from a transmitter, or having large structures between your radio and the signal path. If your radio tends to produce a hissing sound, this could probably be because of a weak signal. The most common interferences are: Hissing ![]() Sounds associated with AM radio interferenceīefore we address the issue of how to improve AM radio reception at home, we’ll first try to identify the type of interference that’s affecting your listening pleasure most. If this dilemma sounds all too familiar, then Radio Fidelity has the perfect blend of tips and tricks you can use to improve your AM radio reception, and boost the AM radio signal. In the worst case scenario, you can’t even tune your radio after fully extending its aerial and moving from room to room. It’ll have you leaping out of your seat and trying to place the aerial at different angles, though this isn’t always guaranteed to work. FM tuner sensitivity: Sensitivity is how well a radio tuner can receive radio signals of varying strength.We all know that hiss, crackling or buzzing noise radios make when the reception is less than perfect.Shared antenna: If you have more than one radio connected to the same antenna via a splitter, the signal will lose strength.On the other hand, if you have a multi-directional antenna, interference is more likely. Antenna type: If you have a directional antenna, it may not receive signals from multiple transmitter locations.Multipath interference: If you live in a valley or an urban area with tall buildings, signals can bounce about and reach the antenna at different times, resulting in noise distortion.Interference can also occur when station frequencies are too close together. Moving or intermittent obstacles: Interference from certain types of electrical equipment, cell towers, and airplanes can affect FM radio reception.Since FM radio transmissions require line-of-sight reception, the curvature of the Earth can also block reception at very long distances. Some home construction materials, such as stucco, concrete, aluminum siding, metal roofs, foil-lined ducts, and solar panels limit the effectiveness of indoor antennas. Stationary obstacles: Radio signals can be affected by physical obstacles such as hills, buildings, and trees.If you're too close to a transmitter, the signal may overpower your radio. Distance: You may be too far from a station transmitter to receive a good signal.
