This can be done with an AM radio dial on the first station. What this means is that you need to check every single electrical device in your car and see if anything emits a signal. What if you’re dealing with interference?Įlectrical interference is fairly easy to spot because most of the time you will hear a buzzing noise coming from your unit.Īnd, as we explained earlier, anything that uses electricity can cause electrical interference. If something is obstructing the signal, there’s not much you can do, unless you plan to change your location. If we were to simplify what is written in the section above, we come to the conclusion that there are 3 potential problems that you could be dealing with. Now you could either try to repair it or get a new one. If the problem persists, chances are your head unit has a problem. There doesn’t seem to be any sign of interference either, so what’s the issue? So you’re not surrounded by tall buildings or trees, the weather is great and your antenna is working as it’s supposed to. Rightly, many of the signal problems are caused by the antenna in one way or another.įortunately, most of these problems can be easily solved. The antenna is said to be the most important component of a radio system. RFI is another type of interference, but – unlike in the case of electrical interference – you might be able to hear much more than just buzzing noises, such as people talking or music. This kind of interference can be characterized by an unpleasant sound, like a buzz, or a hum, or anything else that makes it impossible to listen to the current radio station. Interference can be caused by any device that uses electricity. Usually, most interference problems can be solved, but not if the cause is the sun itself. They affect our lives in many ways, but did you know that they also cause interference? Why? Because there are many obstacles between the receiver (your radio) and the source of the radio waves which you are trying to receive.Īnother cause we can’t do much about is solar flares. The Causes Behind Your Radio’s Weak Signalįirst of all, we need to understand that there are many cases where a weak signal is caused by something that is beyond our power.įor example, your radio will not be able to receive radio waves perfectly if you are in an area with many tall buildings.
