    What communication tool is the most suitable for road trip? Dec 22, 2022
    What communication tool is the most suitable for road trip? There is no doubt that the walkie-talkie is the most convenient. More and more riders will choose to travel in groups for road trip. After all, traveling alone will inevitably lead to loneliness and fatigue.Taking care of each other when traveling together, the walkie-talkie has become an important part of the team's safety and is indispe...

    What is the " kill" function of the walkie-talkie used for? Dec 28, 2022
    Anyone who is familiar with walkie-talkie knows that it have a function - kill, but for green hands, they may not understand it very well. Today we will talk about the powerful and practical function. The "kill" function of radio can make the radio shut down or prohibit transmission by remote control. The ability to turn off the launch function individually is sometimes referred to as "stun". Afte...
  • How to distinguish single call, group call and all call of DMR?
    How to distinguish single call, group call and all call of DMR? Jan 05, 2023
    The DMR(Digital Mobile Radio) can set single call, group call and all call directly through contacts. So what is the difference between them? 1. Single call Literally we can understand that this is a one-to-one call. Each of us will register a DMR ID through the call sign, which is the same as our mobile phone number and is not repeated. If you want to call the other party, you can directly e...
  • Do you know the three scanning methods of walkie-talkie?
    Do you know the three scanning methods of walkie-talkie? Jan 11, 2023
    Scan is a very common and useful feature for amateur radio operators. When they are not sure which frequencies have a signal, they can turn on the scan function. To give an easy-to-understand example, suppose we have built 10 channels, but we are not sure which channel has a signal. At this time, if we turn on the scan function, the walkie-talkie will wait on these 10 channels. If there is no sign...

    How to prevent the radio out of power when going out? Feb 10, 2023
    Sometimes the walkie-talkie is used outdoors or when exercising, but what should I do if it shuts down halfway through the use due to insufficient power? Do the following to keep you prepared. 1. Check equipment in advance This one is the easiest to achieve, that is, we must remember to fully charge the walkie-talkie the night before going out. 2. Switch the appropriate transmit power It is enough...
  • Will rainy days affect radio communications?
    Will rainy days affect radio communications? Feb 16, 2023
    In fact, the attenuation of rain on EMW(electromagnetic waves) below 10 GHz is relatively slight, but for EMW above 10 GHz, the impact of rain attenuation is very obvious.  When EMW passes through the rainfall area, the rain not only absorbs the energy of the radio wave, but also scatters it. This absorption and scattering together form electromagnetic wave attenuation. Scattering can also ca...
  • How much does the gain antenna improve the signal of the walkie-talkie?
    How much does the gain antenna improve the signal of the walkie-talkie? Feb 23, 2023
    As we all know, walkie-talkies can make the signal stronger by adding gain antenna. Today we continue to talk about the topic of gain antennas. First of all, we need to understand the function of the gain antenna. Do you know how satellites receive communication signals? Logically speaking, satellites are far away from the earth. The higher the frequency, the greater the loss. So why do satellite ...

    Do you know the actual talking distance of DMR radio? Mar 02, 2023
    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...
