    How can walkie talkies increase call distance? on 2023-03-06
        Walkie talkies are versatile communication devices that are widely used in various fields. They are commonly used by hiking enthusiasts, construction workers, event organizers, and emergency responders, among others. These devices are advantageous due to their portability and wireless communication capabilities. One of the main concerns with walkie talkies is their call distance. However, many advancements in technology have been made to increase the call distance of these devices. This article explores some of the ways walkie talkies can increase call distance. 1. Power output     One of the most effective ways to increase the call distance of a walkie talkie is by increasing its power output. Power output is the strength of the signal that the walkie talkie transmits. The higher the power output, the stronger the signal is. Most walkie talkies usually have a power output of 1-5 watts. However, some models can be powered up to 10 watts, which significantly increases their call distance. 2. Use of repeaters     A repeater is a device that receives a weak signal from a walkie talkie and amplifies it, then transmits it to another walkie talkie. Repeaters are especially useful in areas where there are physical obstacles that impede the signal, such as mountains, hills, or tall buildings. When using a repeater, the call distance of a walkie talkie can be extended to hundreds of miles. 3. Antenna type     Walkie talkies usually come with a default antenna, which may not be ideal for long-range communication. However, replacing the default antenna with a high-gain antenna can increase the call distance of a walkie talkie significantly. A high-gain antenna has a narrower angle of transmission, which means that the signal is focused in a particular direction, thereby increasing its range. 4. Terrain     The terrain can significantly affect the call distance of a walkie talkie. For instance, if you are communicating in an area with a lot of trees or buildings, the signal may be weakened, and the call distance reduced. Additionally, the ground elevation can also affect the call distance. For instance, if you are standing on a hill, the signal can travel a longer distance than if you are in a valley. 5. Noise reduction technology     One of the most significant challenges of walkie talkies is that they are usually affected by external noise, which can interfere with the signal and reduce call distance. However, some walkie talkie models have noise reduction technology, which cancels out the background noise, thereby increasing the clarity of the signal and making it possible to communicate more effectively over longer distances.     In conclusion, walkie talkies are reliable communication devices that can be used in various fields. Their call distance can be extended through the use of repeaters, high-gain antennas, increased power output, noise reduction technology, and proper terrai...

  • Analog vs Digital Radios: Which One Is Best?
    Analog vs Digital Radios: Which One Is Best? on May 18,2023.
    When it comes to radios, there are two main types available on the market today: analog and digital. While both have their advantages and disadvantages, it can be difficult to determine which is best for your individual needs. In this article, we will explore the differences between analog and digital radios and the pros and cons of each. Analog Radios Analog radios have been around for several decades and are still widely used today. They use a continuous wave signal to transmit information and have a simple design that is easy to use. They are also reliable and have a long battery life, which makes them perfect for long-term use. One of the biggest advantages of analog radios is that they are less expensive compared to their digital counterparts. They are also better for use in areas that have poor cell coverage or weak internet connectivity as they can work without the need for a network. However, the technology used in analog radios has some major limitations. They have a relatively short range and are susceptible to interference from other signals. This can result in poor reception and a lot of background noise. Digital Radios Digital radios, on the other hand, are relatively new to the market and use digital signals to transmit information. They are gaining in popularity because of their superior sound quality and greater range compared to analog radios. They also have many advanced features such as GPS tracking, text messaging, and long battery life. Digital radios also have better security as their signals are encrypted, which means they are harder to hack or listen in on. They are ideal for use in noisy environments, where analog radios can be difficult to hear due to background noise. However, the downside of digital radios is that they are more expensive to purchase and maintain compared to analog radios. They also require a network or internet connection to work properly, which can be a challenge in remote areas. Which One Is Best? In the end, the choice between analog and digital radios comes down to your individual needs. If you are using the radio for simple communication in an area with poor network coverage, then an analog radio would be the best choice. If you need a radio that serves multiple purposes, has advanced features and better security, then a digital radio is the way to go. In summary, both analog and digital radios have their advantages and disadvantages and it is important to consider your individual needs when choosing which one is best for you. While digital radios may be more expensive and require a network, they offer greater range and superior sound quality. Analog radios, on the other hand, are less expensive and can work in areas with poor connectivity. Whatever your choice, both analog, and digital radios provide effective communication solutions.

  • Why are two way radios still used in an age when cell phones are widely used?
    Why are two way radios still used in an age when cell phones are widely used? on 2023-05-13
        Two way radio was a widely respected communication tool before the mobile phone came out. Before the invention of two way radio, people could only communicate with others face to face, which also brought great inconvenience to people's work and life. Therefore, two way radio changed people's way of communication to some extent in that era.     Later, mobile phones were also invented by people. Compared with two way radios, mobile phones are more in line with the needs of people's daily life. In this era, mobile phones have become necessities in people's lives and contain more and more rich functions. So if cell phones are so good, why do people still use two way radios today?     First of all, although the mobile phone is very convenient, but it also has a disadvantage, that is, the mobile phone only in the place of sufficient signal to normal communication with others, so if you go to some relatively remote places, it will inevitably encounter the mobile phone can not receive the signal, so that we have no way to call others, mobile phone traffic is no way to normal use.     While two way radios do not exist in this aspect of trouble, even to the remote mountains, we can also use the two way radio communication smoothly. So many experienced explorers pack their bags with sturdy two way radios for themselves and their companions, so they can stay in touch even if they get lost in the woods.     Secondly, two way radio is very convenient to use. It does not need to dial like a mobile phone. You can contact others as long as you press the button. You can only talk to one person on a cell phone, which can make communication between teams difficult, since you may need to make several calls to notify the whole team.     But as long as there are enough two way radios, people can communicate through them at the same time, so that everyone can hear one person speaking. We also know that mobile phone calls need to pay, after all, communication operators also need to obtain profits, and only when the purchase of two way radio need to spend some money, after the use of the process is not any communication costs, so the use of radio calls can also save a lot of money.     Finally, it is inevitable that nobody will answer the phone when we call others. In this case, we have no way to communicate with others. This is not the case with a two way radio. As long as you speak through the two way radio, the person on the other side can hear you. So many police or security guards will carry two way radios in their daily work, so that their work efficiency can be improved.

    Precautions for using two way radio on May 11,2023.
    1. When the intercom is being launched, keep the intercom in the vertical position, and keep the distance between the microphone and the mouth 3-5 cm. The two way radio should be at least 2.5 cm from the head or body at launch. If a handheld radio is carried on the body, the antenna should be at least 2.5 cm away from the body when it is launched. 2, in the process of use do not turn on and off the action for many times, at the same time to adjust the volume to suit your hearing volume. 3. Do not change the parameters of the intercom. Otherwise, the frequency meter function may be confused, which may cause the intercom cannot be used normally and cause unnecessary trouble to maintenance engineers. 4. Only the antennas configured or approved by the original factory can be used. Without the approved antennas, the antennas modified or added with accessories may damage the two way radio or violate the regulations of the Radio Administration Bureau of the Ministry of Information Industry; And may make the communication effect worse. 5, in use, do not use the hand to hold the antenna, do not hold the antenna to swing the machine around here and threre. 6. In use, the antenna of the two way radio can not be screwed off, otherwise it is easy to damage the internal components when transmitting. 7. Do not use damaged antennas. Minor burns may occur if the damaged antenna comes into contact with skin during launch. 8. The radio antenna is compatible with the frequency of the host. Do not use the antenna that does not match the frequency band of the host, which will damage the two way radio and deteriorate the communication effect. 9, two way radio speaker external magnetism is very weak, avoid in the computer, MP3, PDA, U disk and other electronic equipment accessories for a long time emission, wireless electromagnetic wave may have a certain impact on the use of these equipment; Do not use high power close to the human body for a long time.

  • The structure of two way radio
    The structure of two way radio on May 9,2023.
    Antenna There are many kinds of antennas, such as two way radio rubber antenna, hand-held radio pull rod antenna, vehicle mounted sucker antenna, FRP omnidirectional antenna, Yagi directional antenna, and suction top antenna. Now many two way radios are full frequency segment, 136-174M, 400-470M, although some small manufacturers known as the antenna is full segment, but it is best to distinguish the antenna high and low segment, for the full segment of the machine, frequency above 450M with 400 high antenna, frequency below 420M, Antenna with lower than 400 is much better, especially when the user on the call distance requirements, more attention should be paid to these. The effect of ordinary tie rod antenna is not big, the length of rubber antenna is a great deal of attention, not the longer the better, if the effect is significant, MOTOROLA and other international brands why not do it? The gap between the car suction cup antenna is very big, good to hundreds of pieces or even more than one thousand yuan, the most cheap one is just 40 yuan, it is recommended that we sell more than one hundred antenna, quality assurance, sensitivity is also higher, the distance of the sales of the platform also has a greater help, or that sentence, a good horse with a good saddle. Channel value Some two way radios have displays and some do not. Two way radios without displays generally have 16 channels such as Senhaix 1430, 15 regular channels and one scan channel. Two way radios with display screens generally have 99 or 128 channels such as SenhaiX 8800 and SenhaiX 8600. Moreover, two way radios store 99 or 128 channels, maritime two way radios are generally 128 channels. Status indicator The status indicator of the two way radio refers to the two status indicators of transmitting and receiving. Under normal circumstances, the indicator is out when the two way radio does not work, the indicator is red when transmitting, the indicator is green when receiving, and the signal is not good when the two way radio receives, the green indicator is not always on, but irregular "jitter". If the two way radio battery is low and it is in standby state, the red indicator blinks, indicating that the battery is low. You need to replace the battery. If you do not replace the battery in time, a beep will beep when you press the launch button of the two way radio. Horn Horns of two way radio have several calibers, the sound quality of the speaker and the size of the sound cavity has a large system, the sound quality of the big two way radio is better than the sound quality of the small one. Battery Batteries are an important part of a two way radio. A good battery for a two way radio is like a good  saddle for a good horse. Walkie-talkie batteries can be divided into nickel cadmium battery, nickel metal hydride battery, lithium ion battery. Each of the above batteries is equipped with explosion-proof battery, ordinary battery can not be used in flammable and explosive gas ...

  • How far is the actual communication distance of two way radio?
    How far is the actual communication distance of two way radio? on 2023-05-05
    Radio as a wireless communication tools, and mobile phone contrast has its own advantages: in the set of one-to-one, one-to-many communications, especially the characteristics of the one-to-many is ordinary mobile phone can't compare. With the continuous improvement of the basic functions and the expansion of the main uses of two way radios, two way radios are also widely used in the military, public security organs, security, rescue, public utilities and other government departments. In addition to its application in professional fields, two way radios are also gradually entering People's Daily life. They can also be found in civil occasions such as dispatching, security, property management, construction sites and hotels in daily life.Many customers who have just contacted the two way radio often ask, how far can the radio call?There is a problem about the communication distance of the two way radio, in fact, mainly depends on the communication distance, push power, two key factors, today we will talk about how to know how far the communication distance of the two way radio is? 1. Communication spacing Usually communication spacing within 2-3 kilometers can be regarded as short distance communication, relative to individual users, can buy civil radios. Compared with enterprise customers, they can purchase low-power radios by applying for them. If they want to ensure the actual effect of communication, they can choose professional common radios. If you need to communicate within the city and the communication distance is within 3-10km, you can consider buying a professional walkie-talkie. The Senhaix GT-10 is a good choice. If it is further away, it is best to use the base station power and handheld radio communication, or the vehicle-mounted platform and vehicle-mounted platform communication base platform. We can use the relatively large power of the vehicle-mounted radio. If customers need longer distance or better communication quality, they can use cluster interphones if they do not have their own professional digital trunking . Professional digital trunkings are supported by the wireless communication Internet, so the communication distance is relatively far. Because the two way radios need the support of the Internet, if the two way radios are taken off the Internet, just like the mobile phones are taken off the Internet, even if the calls are face to face, they cannot be made. 2. Sending power Compared with the wireless communication machine equipment, the size of the sending power is particularly important. The same wireless devices, the high sending power products and low sending power products are different from price. At the same time, the difference of sending power also directly affects the stability of wireless network data transmission.Therefore, pay attention to the size of the selected machine and device sending power, is also an important part of the whole process of selecting wireless devices. At present, some of the push pow...

  • What are the problems of two way radios in programming
    What are the problems of two way radios in programming on 2023-05-03
    First, What is the meaning of two way radio programming The traditional analog radio the machine at the same frequency is generally interworking, but if there is a frequency phenomenon after the need to modify to adjust the frequency and CTCSS, this is the need to programming line to link into the radio. When programming the machine, the role of the programming line is to convert the level, and the popular tap is to convert the information sent by the computer into the information that can be read by the two way radio, just like translation Second,problems of two way radios in the programming 1. The two way radio installation file cannot be programmed An error caused by packaging naming may have prevented users from using the installation file. When packaging software, do not use Chinese names or full-angle symbols, use English half-angle characters. 2. When there are errors in the old software, the new software can not be used normally. May be the old software error data programmed into the machine, at this time with the new version of the software to read the machine data will cause errors, encounter this kind of situation, reset the machine or on the existing error of the two way radio first perform a programming operation, (before editing do not read the existing error into the two way radio, but can read the original software has not programmed) 3. After the upgrade software is replaced, the saved data file cannot be opened If the new version of the software does not support data saved by the Japanese version of the software. You can obtain saved data in the following ways:. Use the old software to read the data and program it into the two way radio (the two way radio that has been programmed can ignore this step)· Read the data from the two way radio. Attention: It may cause some unexpected errors, we recommend that it should not be used in this way. The way to do that is to program a new piece of data. 4. After the software is replaced or upgraded, data is read out, causing an error in the programming software. After initializing the two way radio, read data or directly edit data to program (program once first) 5. After the software is replaced or upgraded, files cannot be saved or an error occurs after reading the two way radio. Read data after initializing the two way radio or directly edit data to be programmed (program once first). 6. An error occurs during the installation process, and the message "Error occurred while trying to replace an existing file: DeleteFile failed: Code 5 denies access Open" Task Manager ", "Process", find all the running software programs of this programming and stop it. And then reinstall 7. After the intercom is powered off, an error occurs in the read frequency  or programming and the message Cannot open the communication port is displayed. Check whether the serial port ID is correct on the serial port setting screen. Plug and unplug the programming line (PC). 8. How to check the update of the same ve...

  • Why do we need an explosion-proof radio?
    Why do we need an explosion-proof radio? on 2023-05-02
    Literally,the general people rarely contact explosion-proof radio, can only merely understand the use is explosion-proof function, can be applied to the explosion-proof area, as for what principle, explosion-proof radio specific what characteristics are not known. Explosion-proof radios refer to two way radios used in different flammable, explosive, dust and other environments according to different explosion-proof certification levels. Explosion-proof radios are attached with Ex explosion-proof certification mark, indicating that the product has passed the national explosion-proof testing agency certification, can be used in specific explosive gas environment. The principle of explosion-proof radio: Explosion often brings great loss of life and property. Preventing the release of combustible materials, which is often the cause of explosive conditions, and preventing the creation of effective ignition sources are widely used methods to reduce the risk of explosion. And the use of correct equipment can be more effective prevention. An effective source of ignition may be one or a combination of: lightning, open flames, excessive surface temperatures, electric arcs or sparks in electronic equipment, sparks caused by different potentials, mechanical sparks (friction or collision), electrostatic discharges, radio-frequency radiation, and associated radiation (lasers). Why do you need an explosion-proof radio? From the above we can see that the use of explosion-proof radio in special occasions is a necessary communication equipment, then explosion-proof radio, is a function of explosion-proof radio, and use is more practical than the general two way radio.        Ordinary mobile phone calls can only be one-to-one, while two way radio supports one-to-many call mode, which can highlight its advantages in the work scene of personnel scheduling, and well solve the problem of division of labor and decision. Explosion-proof radios can talk without any network support, and no call charges are generated. They are suitable for relatively fixed and frequent calls. In some special working background environment, such as very noisy production workshop, pharmaceutical workshop, the voice of the walkie-talkie is clear, convenient communication, and the two way radio can achieve a hundred calls, very practical! The difference between explosion-proof radios and ordinary radios Let's start by understanding what an explosion-proof radio is. This type of two way radio mainly refers to the ability to work in the environment of explosive gas, rather than itself can resist explosion. At present, it is mainly used in harsh environment and dangerous combustible gas or dust environment, such as petrochemical, coal, chemical, thermal power, food processing and other industries. Our commonly used analog and digital two way radios mainly rely on electromagnetic wave to transmit signals, and electromagnetic wave transmission mainly uses the continuous conversio...
