Question 1: How to know the frequency of the walkie-talkie? There is a frequency meter. This thing is not expensive, costing a hundred yuan, or some home appliance repair masters have it, but this can only test the transmitting frequency, not the receiving frequency. , if the transmission and reception are on the same frequency, it is okay, but the transmission and reception are on different frequencies, or there is mute sound on the reception, then there is no other way. The only way is to read the machine frequency through the frequency writing software, and then modify it
Question 2: How to know the frequency of a walkie-talkie in two ways
1. Use a frequency meter. When a fixed-frequency walkie-talkie transmits, the frequency meter will display the frequency value.
2. If the frequency-adjustable walkie-talkie has a frequency scanning function, you can also find it by using the fixed-frequency machine's transmission signal. It is best to know the frequency range of the fixed frequency machine in advance.
Generally between 450-470 is a high-end machine. Generally between 400-470. And remove its battery, and you can find the frequency range on the back of the machine.
Question 3: How to know the frequency band of a fixed-frequency walkie-talkie in two ways
1. Use a frequency meter. When the fixed-frequency walkie-talkie transmits, the frequency meter will display the frequency value. Come.
2. If the frequency-adjustable walkie-talkie has a frequency scanning function, you can also find it by using the fixed-frequency machine's transmission signal. It is best to know the frequency range of the fixed frequency machine in advance.
The sea-like range between 450-470 is a high-end machine. Generally between 400-470. And remove its battery, and you can find the frequency range on the back of the machine.
Question 4: How to set the channel for the walkie-talkie? The two mobile stations can communicate with each other when they are tuned to the same frequency and are within signal coverage. The fact that the receiving and transmitting are not on the same frequency as you mentioned should be a case of connecting to a relay station. After the walkie-talkie is connected to the relay station, since the relay station uses a duplexer to connect to the transceiver, the frequency of the received signal and the transmitted signal are different. The frequency difference of the general amateur relay station is 5, and the reception is 438.000, then the transmission is 433.000. For the use of frequency reading software, your Shengsheng can jump to the frequency mode, and directly display the current frequency, whether to lower the frequency and subtone settings on the screen. Since Haoyitong's machine does not have a specific model, I don't know if it has a display and whether it supports frequency display. Another thing to note is that if two or more mobile stations are communicating in direct frequency mode and want to keep it secret and send and receive sub-tones, this approach is actually wrong. This method can only maintain the communication of several devices without being disturbed by others, but others can receive your signal on the same frequency, so there is no frequency confidentiality.
If you want to learn radio knowledge, you can join a local radio enthusiast group, or come to Harrow CQ, the largest radio enthusiast forum in mainland China.
Each interval is 000.005. Is this normal? This is normal, and the frequency hopping is adjustable, 005 is the minimum interval.
Question 5: How to search the frequency of nearby walkie-talkies? The settings of each model of walkie-talkies are different. Please refer to the manual for specific settings.
The following takes the TK208-308 frequency modulation method as an example:
1. Clear frequency: press and hold PTT+CSET+boot;
2. Write frequency: press MONI , the frequency number 150.00 displayed on the LCD panel flashes. At this time, call up the required frequency point. Press CSET to select the channel number (starting with the first frequency 01). Press CSET to store the receiving frequency point; p>
3. If the transmission is in different frequencies, press MONI again to call up the transmission frequency point, hold down the PTT button, and press CSET and REV twice to display +.-
4. Display CH status: press and hold the PTT key and REV key to turn on the phone;
5. Check the frequency: press and hold PTT+CTCSS to turn on the phone, and then press LOW to enter the maintenance mode.
Question 6: How to know the frequency of other people’s walkie-talkies. Generally, walkie-talkies that cannot be seen on the screen are industrial walkie-talkies. You can set the frequency band between 450-470, press the button to transmit and then search You should be able to find a walkie-talkie with a screen by searching 450-470
Question 7: How does a frequency meter measure the transmitting frequency of a walkie-talkie? I don’t know what kind of walkie-talkie you have and what frequency meter you have. We use a handheld frequency meter to measure the handheld walkie-talkie. , just turn on the power of the frequency meter and put the antenna close to the walkie-talkie antenna. When the walkie-talkie is transmitting, its transmitting frequency will be displayed on the frequency meter.
I hope my answer can help you.
Question 8: How to adjust the frequency of a wireless walkie-talkie? Handset (walkie-talkie)
Today, when mobile phones are very popular, why do people still choose to use walkie-talkies? This is because walkie-talkies have many unique features compared with mobile phones:
1. Walkie-talkies are not restricted by the network. In places not covered by the network, walkie-talkies allow users to communicate easily
2. The walkie-talkie provides one-to-one and one-to-many calling methods. Just press and speak. It is simple to operate and makes communication more free. Especially in the case of emergency dispatch and collective collaboration work, these features are very important. .
How far is the communication range of a walkie-talkie?
The talking distance of conventional walkie-talkies is generally 3-5 kilometers, but when there are obstacles such as tall buildings or mountains, the talking distance will be relatively shorter. When supported by the network, the call range of the walkie-talkie can reach dozens of kilometers.
Can mass consumers buy walkie-talkies?
Mass consumers can also buy walkie-talkies, but in the past, to purchase and use walkie-talkies, they had to apply to the local Radio Regulatory Commission ("WRC" for short), obtain a radio station license and pay frequency occupancy fees. Starting from December 6, 2001, my country has opened up the civilian walkie-talkie market. There is no need to go through any formalities when using 400MHz civilian walkie-talkies with a transmitting power of less than 0.5 watts.
Can the walkie-talkie make calls?
With network support, the walkie-talkie can be used to make calls. But if it is just a regular call between stand-alone phones, the function of making a phone call cannot be realized.
Is there a charge for using a walkie-talkie?
There is no charge for making calls using a regular walkie-talkie. No matter how frequently you use it, you only need to pay a few dozen yuan in frequency occupation fees for each walkie-talkie every year. If you use a public walkie-talkie, you do not need to pay any fees.
1.1 Use common sense
"Walkie" and "handheld radio" are both radio stations. What we usually call "walkie-talkie" is actually a radio station. In terms of names, there are usually many Misunderstand. For example, many people think that "walkie-talkies" are used in pairs, or that "radio stations" are such a profound thing. In fact, it is easy to understand - including the radio part of the audio system installed in your car and the radio of your Walkman, they are actually a large category of things. Translated into English, these are all called RADIO, but the radio stations we are talking about usually have both. Receiving and transmitting functions, a conventional communication tool that can be used to transmit radio signals to communicate with other people.
1.1.1 What is a radio station?
In fact, the broadcast we listen to every day is radio, but it is emitted by a "broadcast station". The power of the radio station is extremely high, the position of the transmitting antenna is extremely good, and the coverage area is extremely wide, so it covers a wide area. Any receiver (that is, a radio) can receive its signal and convert it into sound for broadcast.
Now imagine that you and your friend each have a radio (radio receiver) "micro-radio station" (radio tran***itter) in the car, which is the radio station (Radio tran***itter) that everyone is discussing. Tranciper). It has both transmitting and receiving functions and can talk to each other.
1.1.2 Frequency M frequency point M frequency band
Think about the 97.4MHz and 103MHz that everyone usually listens to, which are the frequencies. It may be right to say the frequency point, but it is a bit far-fetched to say the channel. , but they often say "channel 103.9, channel 97.4", which is really misleading.
97.4MHz is the frequency of the music station, 103MHz is the frequency of the traffic station, and 438.500MHz is the transmitting and receiving frequency that amateur radio enthusiasts in Beijing can legally use (the 400MHz frequency band, and other frequency bands are also available Legal frequency points of amateur HAM)
Obviously, our frequency modulation (FM) radio does not support reception of more than 430 MHz (it seems that the FM part is between 86-107MHZ), so if you want to use the 438.500MHZ frequency To transmit and receive signals online, you need professional equipment, which is what we usually call "a car station/handheld station/base station that supports amateur frequency bands" and so on.
If 438.500 is a frequency point, then it also belongs to the 430MHZ frequency band. We probably call 430.000-439.999 the amateur 400M frequency band, also called the amateur 70CM (centimeter) band (which is the term for wavelength). Because this frequency band is mainly allocated to amateur radio operators.
Primary HAMs may have more exposure to the often-called "2-meter band" or "140 MHz amateur band", which is between 144.000-145.999MHZ, which is also the frequency range that HAMs can use.

Question 9: How to know the frequency band of a fixed-frequency walkie-talkie in two ways
1. Use a frequency meter. When the fixed-frequency intercom transmits, the frequency meter will display the frequency value.
2. If the frequency-adjustable intercom has a frequency scanning function, use the fixed-frequency intercom. You can also find it by sending a signal. It is best to know the frequency range of the fixed frequency machine in advance.
Generally, it is between 400 and 470. Remove its battery and you can find the frequency range on the back of the machine.
Question 10: The frequency and channel mode of the walkie-talkie. The frequency mode can know the frequency anytime and anywhere, but the channel mode can only know the number of channels but not the number of channels. What is the frequency?,,
