For different users and different industries, radios can generally be divided into professional radios and amateur radios.
On different occasions, these two walkie-talkies play their respective functions, so where are the differences?
Professional walkie talkie
Most users of professional radios are used in the professional business of group teams. Therefore, the professional radio walkie-talkie is characterized by simple and practical functions. In the design, there are a variety of communication interfaces for users to make secondary development. The frequency report setting is mostly through computer programming, the user can not change the frequency, the panel displays only the number of channels, does not directly display the frequency point, the frequency has good confidentiality, the frequency stability is also high, and the frequency is not easy to run.
In long-term work, its stability and reliability are high, and the operating temperature range is wide, generally ranging from -30 degrees to +60 degrees. The working frequency of the professional machine is a part of V high section (148-174MHZ) and V low section (136-160MHZ) in the VHF section. The other part is the whole section (136-174MHZ). However, in the UHF band, most of the U-segment (450-470MHZ) and U-segment (400-430MHZ), very few U-segment (400-470MHZ). The performance, reliability and stability of professional machines are higher than those of amateur machines. The price is naturally higher than that of amateur machines, and some are even higher.
A radio walkie-talkie designed and manufactured to meet the needs of radio enthusiasts. Such walkie-talkies can also be called “playing machines”, and fans who play walkie-talkies are called “HAM” or “ham”. Due to the limited frequency range of the radio, the environmental conditions and usage requirements of the radio are different from those of professional walkie-talkies. The main feature of the amateur machine is that it has a small size, complete functions, and frequency scanning. The frequency can be directly set on the panel, and the frequency point is displayed on the panel. Its technical indicators and equipment for this amateur personal radio service, each country has opened a dedicated frequency band allocated to amateur radio sports enthusiasts. The frequency bands opened in China are 144?146MHZ and 430~440MHZ, which are also commonly used in countries all over the world. In October 2001, the Radio Frequency Plan of the People’s Republic of China issued by the National Radio Administration of the Ministry of Information Industry specifically stated for amateur radio enthusiasts and amateur services. “Amateur service: self-training and mutual communication for amateur radio enthusiasts. Radiocommunication services for technical research. Amateur radio enthusiasts refer to those who are formally approved and interested in radio technology, whose interests are purely personal hobbies and do not involve profit.”
