How to tune the radio

 The relationship between walkie-talkie and walkie-talkie frequency is just like you have to buy a new phone number (a number), you have to combine the two to talk to someone else's phone. So be sure to remember your frequency point, tell your frequency point to each other, communication with each other will become more convenient and simple. Because the brand, signal and frequency band of intercom are different, it is necessary to make two or more intercom through frequency modulation. Walkie-talkies are divided into professional walkie-talkies, amateur walkie-talkies and civilian walkie-talkies. The frequency modulation methods of these three walkie-talkies are different.

How do amateur walkie-talkies tune?

Amateur intercom body can directly use the knob of the body to adjust frequency, generally there is a fixed stage, as long as the two intercom to the same frequency band can talk.

How to adjust frequency of civil intercom?

The country has regulations on the frequency band of civil walkie-talkies. The open frequency band is 409-410mhz, which is divided into 20 channels, called "public channels". Walkie-talkies with less than 0.5 watt power cannot be programmed to change the transmission frequency.

How to FM professional walkie-talkie?

The frequency modulation method of amateur walkie-talkie and civil walkie-talkie is very simple. The focus of this article is to introduce the frequency modulation method of professional walkie-talkie. Professional intercom must be to want to write through the computer, read out and modify frequency, this must use to write frequency line and software among them, this is the same as the USB line that computer and mobile phone photograph connect, after inserting, must have drive, this software is quite then drive. Once the equipment is ready, the frequency of the intercom can be read and written. Professional intercom frequency modulation only need 6 steps: read frequency point -- frequency input -- parameter setting -- save data -- load data -- exit software

1, read the frequency point: first install the intercom corresponding write frequency software on the computer, connect the computer and the intercom with the data line, use the write frequency software to read programming data.

2. Frequency input: After reading good frequency or new documents in the interface directly with number keys input frequency, input the appropriate frequency in the corresponding frequency range, the frequency of receiving in the first column, such as 414.225, upload, and press enter to launch the default frequency of receiving the same, if the frequency of the emission and receiving of the same direct press the return key, if different input again, losing the press the return key, Let's go to the third column.

3, parameter Settings: the main set emission limit time (to avoid long time machine fault set a protection, launch, the default value of 180, the general is adjustable to 60), noise levels (a little higher sensitivity and values larger sensitivity is lower), boot prompt (Yes is a boot prompt, No is not prompt boot. Enable means that the battery power saving function is enabled. Disable means that the battery power saving function is disabled. The default value is Enable power saving, broadband/narrowband (the default value is Wide broadband). You are advised to use Wide bandwidth because narrow band is prone to failure.) End and exit after modifying the above parameters. You must write frequency before saving the data to the intercom.

4, save data: after the intercom reading frequency reading or frequency setting, the data can be saved, so that the next machine needs to write frequency without input frequency and related parameters, reduce the time to improve efficiency, but also reduce the probability of error.

5, loading data: for the computer has saved the frequency data, loading data can be directly used to write frequency to the intercom, eliminating the trouble of frequency, but also reduce errors, improve efficiency. After the loading is completed, the frequency parameters previously set are displayed in the interface, and then you can write frequency operation.

6, exit software: write frequency end can exit.

Instant X6 intercom memory channel 16, if you need to add or modify the frequency and you have not learned the above tutorial, you can let customer service help you write frequency. 3W power frequency range of 400~470mHz, suitable for hotels, KTV, property, construction sites, restaurants and other occasions.

Gothic clothing

  The black of goth dress forever or it is the dress of dark color series [a few are red], color collocation is red black commonly, complete black or black and white, wearing a lot of conspicuous religious decorations, but change belief almost every day, never wear gold jewelry, it is not good communication actually on disposition. The style mainly reflects the feeling of acute Angle such as spiky shape and serrated edge at the lower end of garment front. Gothic dress   is always black or dark series of clothes, wearing a lot of conspicuous religious decorations, but almost every day to change their beliefs, never wear gold jewelry, personality is actually not sociable. Punk criticizes everything; Goth sees through everything. Punk thinks day is night; The Goth only likes the dark. Punk likes black; Goth likes black and white. Punk body strong for beauty; Gothic was beautiful in curves. The clothes of The Goths are generally in loose bright colors, such as purple, dark blue an...

What are the different types of neon lights?

  Technically, there is only one type of neon, and it takes about five years of practice to bend the glass to a high enough quality to make a real neon sign. We can make it in-house for you. If you are interested in the differences between "different" types, we hope to answer your question about what different types of neon are here. This page is still a work in progress. We'll add the video in due course, but for now we've explained it below. Neon lights (made of glass only) How are neon lights made? Neon lights   are made from straight pieces of glass that are precoated with phosphors. The glass is heated by hand over a flame until it softens, a bit like spaghetti. Once the glass has softened, it is removed from the flame and bent into a paper pattern by hand, while air is also blown into the tube to maintain its shape and diameter, either through a mouthpiece or directly into the end of the tube depending on how it is bent. After each bending outside the flame, the...

Does UV sterilizer really effective?

UV sterilizer - what is it? The UV sterilizer is a device designed to sterilize primarily air and various flat surfaces. It complements the disinfection and sterilization processes of tools in an autoclave   sterilization , carried out in places such as treatment rooms, operating theatres in hospitals and other healthcare facilities. It occurs mainly in the form of mercury lamps, which job is to sterilize the air. In the era of a pandemic, it is also used in public transport, for example in buses in China, where it is used to minimize the risk of droplet coronavirus infection.   This type of sterilizer uses UV radiation, specifically UV-C. It is short-wave radiation and the wavelength ranges from 210 to 328 nm. It works by creating thymine dimers, changing the structure of nucleic acids, and consequently damaging the microbial DNA. Such lamps, however, do not completely remove all viruses and bacteria - they do not eliminate their spore forms, which can also be a threat. There...
