The earpiece is an electrical to acoustic transduction device that traces its history back to 1924 when it was invented by German scientist Eugen Beyer. As an accessory for intercoms, it serves to make them easier to use. The advantage of using a walkie-talkie earpiece is that it can keep quiet and prevent information leakage. Usually, you need to hold the walkie-talkie in one hand to talk. With t...
Everyone knows the importance of UHF/VHF bands height to communication distance and effect. On the top of the mountain, it is possible to communicate with quite distant stations with only common handheld radio. However, we cannot stay on top of the mountain all the time. If there is a device that can help us transmit signals at a high place, then we can make full use of the advantage of heig...
DMR radio is one of the many types of walkie-talkies that have been recognized and favored by many users in recent years. What is the difference between DMR radio and analog walkie-talkie? Let's talk about this topic this time. What is DMR? DMR stands for Digital Mobile Radio and is an international standard that has been defined for two-way radios. The European Telecommunications Standards Instit...
1.What is scrambler？ The scrambling function of the analog walkie-talkie is to change or mix the sound of the broadcast and the information of the radio so that people can only receive and understand it through a specific frequency or channel. It is an important means to ensure that the transmission content of radio waves will not leak privacy and prevent eavesdropping. From a functional point of ...
Walkie-talkies are widely used in public utilities, emergency industries, transportation and other fields, and construction sites are also one of the places where walkie-talkies are most frequently used. So what kind of walkie-talkie should you choose on the construction site? Today let’s talk about this topic. For working environments with a lot of dust, it is required that the walkie-talkie shou...
With the development of the economy, the people's requirements for long range communication have increased, and DMR radios have gradually begun to be used in public fields such as taxi dispatching, security, property management services, construction sites, hotels and restaurants. So how many kilometers can the longest call distance of a DMR radio reach? In an ideal situation (without any obstruct...
The role of the repeater in two-way radios is to increase the communication distance of the radios. When the distance between two radios exceeds the range of the radio signal, the radio will not receive an effective signal, requiring the use of a repeater. The repeater, also known as a relay station or forwarding station, is an essential equipment in the field of specialized mobile communication. ...
DMR（Digital Mobile Radio）is a digital radio communication standard developed specifically for professional and commercial applications. On the other hand, analog radio refers to traditional radio systems that use analog signals for communication. So, can DMR radios communicate with analog radios? The short answer is no. DMR radios cannot directly communicate with analog radios because they u...
