最近、初心者の趣味人の間では digital radios when they choose two way radios . Of course, they do not even know what digital radios are. They will say that digital radio is dual-purpose, and is better than analogue radios. Digital radios have long been popular, and enthusiasts often argue about which two way radio to choose. If you are a new Ham, you must have considered your choice, and this article can help you. Analog radio and digital radio Analog radio is traditional. It has been around for decades and made great contributions to human society. It entered commercial use in 1933, and of course it had been used in national defense for more than two decades before that. At that time, radio greatly improved the efficiency of information transmission, communications equipment business processes were rapidly evolving trends, radio was the most superior mode of communication, all fields depended on it. After decades of development in analog radio, it had already reached a point where the trend was reaching its peak, so experts created and invented more advanced digital radio systems. Analogue radio is no longer scalable. digital radio is completely different. It uses better encoders, improves sound quality at a certain level, and transmits data while talking, so it is relatively expensive. The emergence of digital radio makes the wireless communication field have a development trend of leaps and bounds compared with simulation, there are mainly the following kinds: 1, larger coverage area; 2, video and voice communication quality improvement; 3, a variety of colorful background management functions. But analogue radio also has some distinct benefits. Analog radio has been the primary and only method of communication networks for a long time. Although the current digital technology is becoming more and more popular, most amateur radio enthusiasts still use analogue radio technology to communicate. However, with the continuous development trend of digital technology, more and more technical professional radios have already begun to transform into digital radios. Digital radios provide many new functions for business service customers. Data encryption, one-to-one communication. Originally, mobile phones used analogue radio, but as more and more people began to use mobile phones, communications operators were forced to move to data, which offered greater capacity and new uses. What you can get depends on how much you can pay, which means you can buy a well-known brand and model specifications of wireless walkie-talkies . For example, DMR digital radios have at least 30 percent better battery life than analogue radios, which is very useful. The standard analogue radios, when you get close to the edge of the data signal, will start to abate, and at this point you can hear a lot of noise, even intermittent data signals, whereas the digital radios, no matter how far you get away as long as the data signal coverage area, the quality of the digital signal is almost the s...
