Going out on a hot day is not easy! not easy! On the road, listening to the radio is also a good choice. Hey, don’t say it, some radio DJs have a very magnetic voice. Listening to the humorous stories from the host on the radio, you can also learn about real-time road conditions. , why not do it. However, there are times when this car radio is not worry-free. Sometimes the signal is extremely poor and cannot receive 2 stations. . . Some car owners will say: "There is no interference in underground parking lots, tunnels, etc., why can't you receive the signal?
1. The radio receives the broadcast signal through the antenna, and the reception quality of the signal is affected by various environmental factors, such as mountainous areas, tunnels, under the overpass and other areas with weak signals, making it difficult for the radio to receive signals.
2. In cloudy, rainy, foggy, snowy and other bad weather conditions, the radio signal is relatively weak.
3. When the vehicle is equipped with some equipment that has not passed the relevant electromagnetic compatibility test (such as some driving recorders, car mobile phone chargers, etc.), the circuits inside these equipment will radiate large interference signals to the outside, which will affect the to the radio to receive the station normally.
As long as there is no environmental interference, the radio can be normally received, indicating that there is no problem with the radio. In some areas where the signal is weak, you can manually adjust the frequency band to receive the sound, but it may be accompanied by noise at this time.
