The same frequency is the premise that two walkie-talkie scan talk. If they are not on the same frequency, even walkie-talkies of the same brand and model cannot talk; if the frequency is the same, even walkie-talkies that are not of the same brand can talk. So it matters.
Generally speaking, there are two types of handheld radios: a professional walkie-talkie, and an amateur walkie-talkie, which are different methods of tuning the frequency.
The
amateur walkie-talkie can directly use the knob that comes with the body to tune the frequency, as long as the two walkie-talkies are tuned to the same frequency band, you can talk.
Professional walkie-talkies need to be connected to a computer to tune the frequency, just like connecting a mobile phone to a computer, to read and write the walkie-talkie frequency through data lines, drivers, and software.
When the two walkie-talkies have different frequencies, how to write the frequency to the walkie-talkie? It is mainly divided into the following four steps:
1. Install the programming software on the computer, and connect the walkie-talkie to the computer with a data cable;
2. Open the programming software, press the alt key to pop up a window, use the arrow keys to control the left and right, and press the Enter key to confirm;
3. Read the data, press the Enter key after the reading is completed, a series of frequency point data will appear;
4. Read the data you need from the machine and directly cover it to another machine, and the two walkie-talkies can talk.
Note that what we generally buy are frs walkie-talkie. The country has regulations on the frequency band of frs walkie-talkie. The open frequency band is 409-410MHz, which is divided into 20 channels, called "public channels".0.5 watts of power below the walkie-talkie can not be self-programmed to change the transmission frequency.
