Why Car Radio Is Essential to Keep
The Role of Car Radio in Extreme Weather
Car radios play a crucial role when facing extreme weather conditions like typhoons and floods. In such situations, communication equipment often fails, and mobile phones may lose network connectivity. Repairing these systems amidst storms can be challenging, making car radio indispensable.
Car Radio: AM and FM Explained
AM/FM modes divide the car radio's functionalities. AM, or amplitude modulation, operates on 500-1600kHz medium wave frequencies, enabling car radio waves to travel hundreds of kilometers. This extensive range makes AM car radio a reliable source for emergency broadcasts during severe weather.
Benefits of AM Car Radio
The longer wavelength of AM ensures car radios can bypass obstacles effectively, maintaining communication over great distances. As recent legislation reflects, AM car radio is prioritized for emergency information dissemination in challenging conditions.
Limitations of FM Frequency in Car Radios
FM frequency modulation, although offering better sound quality for car radio, has a limited transmission range of tens of kilometers. Hence, when urgent warnings are needed, AM car radio is more suitable. The recent US House bill emphasizes retaining AM for reliable car radio communication during extreme events.
Conclusion: Why Car Radio Matters
In regions like the United States, prone to frequent typhoons and high car ownership rates, the car radio remains a vital tool for receiving external information. Maintaining AM car radios ensures citizens are informed and safe during severe weather conditions.
