Most users of professional radio intercom equipment 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. Most of the frequency report settings are 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 confidentiality is better, the frequency stability is also higher, and it 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.
