1, download the frequency writing software. When downloading the frequency writing software, first look at the brand and model of the walkie-talkie you bought, and then download the required frequency writing software from the official or third-party website according to the model. The picture below shows official website of Kelixun intercom.
2. Some contract walkie-talkies don't have official website. If they can't download it, they will ask the dealer for it. However, some dealers may not provide us with frequency writing software for their own benefit. At this time, it depends on personal skills. After installing the frequency writing software, we can write the frequency. Open the frequency writing software, and the interface of the frequency writing software is shown in the figure below.
3. Reading frequency. Turn on the power switch of the target interphone, click Programming → Read data from interphone (R) in turn, open the dialog box for reading data from interphone, and click OK to start reading all data of interphone, as shown in the following figure.
4. After reading the data, get the information of each channel of the target intercom. Because this pair has 16 channels, the frequency writing software lists all the information of 16 channels, as shown in the following figure.
5. Click the "Save" command button on the common toolbar to save all the channel information of the target interphone with the file name of 9088.dat.
6. FM. Unplug the target walkie-talkie and connect it to FM. First, perform a frequency reading operation. If the frequency can be read normally, it means that the communication between the walkie-talkie and the computer is normal, otherwise it is necessary to check what the problem is.
7. Click Programming → Write Data to Intercom (W) in turn to open the Write Data to Intercom dialog box, click OK to start writing data to each channel of the target intercom, and when the data is finished, the Finish dialog box pops up, and click OK to close the current dialog box. Then the frequency modulation is completed.
The difference between a handheld phone and a walkie-talkie:
First of all, the definition is different:
1, handheld radio: people's abbreviation for handheld radio. Mobile phones are generally in FM band, and short wave band is rare (for example, GP328/338 of MOTO, MT 1000, etc.). ).
2. walkie-talkie: the English name of the walkie-talkie is two way radio, which is a two-way mobile communication tool. It can make calls without any network support, and there is no telephone charge, which is suitable for relatively fixed and frequent calls. There are three kinds of walkie-talkies: analog walkie-talkies, digital walkie-talkies and IP walkie-talkies.
Second, the frequency is different. According to the Regulations of People's Republic of China (PRC) on Radio Frequency Division 200 1, the legal frequency of mobile phones is:
1、 144.000- 145.800? Amateur service dedicated frequency band.
2, 430.000-435.000 amateur service as a secondary business and other business * * * frequency band.
3, 438.000-440.000 amateur service as a secondary business and other business * * * frequency band.
4. According to the standard wavelength of 0.025MHz stipulated by China, there are 73 "dedicated" available frequency points between144.000-145.800mhz; There are 282 available frequency points between 430.000-435.000 MHz and 438.000-440.000MHz.
