If you want to upgrade, you need to send it back for debugging.FM /AM Band: When hiking, camping, or climbing in remote areas or mountainous areas, mobile phone signals may be unstable. FM radio, with its portability and no need for a network, can receive weather forecasts, emergency notifications, or music programs.

MW Band: Medium wave signal coverage is usually tens to hundreds of kilometers (depending on the transmission power and terrain), suitable for receiving local radio programs, especially in rural or remote areas, where medium wave is the main broadcasting method.

LW Band: Radio enthusiasts and collectors/those seeking emergency communications. Due to its technical characteristics and historical background, the LW Band holds particular appeal for radio enthusiasts. They may be interested in exploring long-distance signals and listening to historical long-wave stations. Long-wave signals have strong penetrating power and long ground wave propagation distances (up to hundreds of kilometers), potentially providing reliable emergency communications or broadcasting services when natural disasters (such as earthquakes and floods) disrupt other communications.

SW Band ：radios are suitable for those who need to communicate across regions, obtain emergency information, listen to international content, or explore radio, especially in outdoor environments without network coverage, during disasters, or during international travel. Their core advantages lie in long-range coverage and disaster resilience, but choosing the right device based on actual needs and usage scenarios requires mastering basic operating techniques.

VHF/UHF Bands: These radios are suitable for those who need short- to medium-range communications, emergency information, outdoor activities, or professional research. They offer advantages such as strong interference resistance and coverage of specific critical frequency bands (such as weather alerts). However, considerations should be given to legality and device compatibility.

CB Band: Many amateur radio enthusiasts use CB as an entry-level radio device for learning communications skills or casual conversation. CB can be used as a backup communication tool during activities such as hiking, camping, and mountaineering (especially in remote areas with limited mobile phone coverage). In rally racing, off-road racing, and car tuning events, CB is used for real-time communication between drivers or between teams and command centers.

WB Band: The application population covers a wide range of groups from professional technicians (such as engineers and researchers) to ordinary users. Its core advantages lie in higher bandwidth, lower latency, and clearer signal quality. It is suitable for scenarios requiring high data transmission rate, high resolution or high fidelity.

AIR Band: Used by a wide range of users, from pilots to researchers, and applied in key areas such as aviation safety, drone technology, satellite communications, and emergency response. The choice of specific frequency band depends on transmission distance, data rate, interference environment, and regulatory restrictions.
