为什么不能随意使用无线电台?和所有的汽车公用一条道路相似,所有的无线电台都公用同一个无线电频谱进行通信。如果没有科学管理,将会造成互相干扰,乃至发生重大事故。因此全世界都十分重视无线电波的管理和协调。第二次世界大战期间,世界性国际合作基本停顿,唯独世界无线电管理始终维持正常协调,可见无线电管理的重要性。 Why not use a radio station? Like all cars on a common road, all radios share the same radio spectrum for communication. Without scientific management, it will cause mutual interference and even major accidents. Therefore, the world attaches great importance to the management and coordination of radio waves. During the Second World War, the international cooperation in the world basically stopped. Only the radio management in the world maintained normal coordination at all times, showing the importance of radio management.
