The communication distance of general walkie-talkies is within 2-3 kilometers, the communication distance of professional walkie-talkies is within 3-10 kilometers, the communication distance of commercial walkie-talkies is between 800 meters and 8 kilometers, and the distance of civilian walkie-talkies is shorter, with an open space of 3 kilometers.

In addition to its growing popularity, advances in DMR radio technology have also become a hot topic in industry news. Manufacturers and developers continue to innovate to enhance the capabilities of DMR radios, such as improving audio quality, extending battery life and extending range. These advancements not only improve the user experience, but also make DMR radios more adaptable to the evolving communications environment.

The phase-locked loop and voltage-controlled oscillator (VCO) generate the transmitted RF carrier signal.

​Walkie-talkies have long been a staple of communications technology, with their versatility and reliability making them an essential tool for a wide range of activities.

If there is no sound or low sound during use of the walkie-talkie, you should first check whether the battery voltage is sufficient.

​One of the biggest advantages of DMR radios is their ability to transmit digital audio signals. Unlike analog signals, digital audio signals are less likely to be distorted by background noise or interference from other radios.
