        In today's world, communication technology has evolved tremendously. There is an overwhelming range of two-way radios available in the market, each with different features and specifications. Among these features, one critical aspect that is gaining popularity is the waterproof and dustproof feature. This feature ensures that the two-way radio can resist water and dust.     However, not all two-way radios have this feature. Thus, it is essential to know whether the two-way radio you plan to purchase is waterproof and can withstand dust. In this article, we will be discussing the two-way radio's waterproof standard and the dustproof and waterproof level that a two-way radio needs to meet. Waterproof Rating Standard for Two-Way Radios     When it comes to a waterproof rating, we generally refer to the International Protection Rating System or Ingress Protection (IP) rating. The IP rating is a standard that categorizes the degree of protection against the entry of foreign objects, such as dust and water. The rating system consists of two digits, where the first digit denotes the level of protection against solid objects and the other digit signifies the level of protection against water. Dustproof and Waterproof Level for Two-Way Radios     A two-way radio with an IP rating of IPX7 or IPX8 is considered waterproof. This means that it can survive submersion in water for up to 30 minutes or more, depending on the rating. An IPX7-rated two-way radio is designed to resist water immersion for up to 30 minutes at a depth of one meter. An IPX8-rated two-way radio can withstand being submerged in more than one meter of water.     On the other hand, a two-way radio with an IP rating of IP5X or IP6X is considered dustproof. This means that it has a high level of protection against entry of dust and other small particles. IP5X can resist larger particles like sand, while IP6X can resist the entry of fine dust particles. Why Waterproof and Dustproof Two-Way Radios Are Essential?     The waterproof and dustproof feature is essential in various scenarios, such as emergency communication during a natural disaster or outdoors activities. These features ensure that the two-way radio can operate reliably in harsh conditions. It is crucial to note that a non-waterproof or non-dustproof two-way radio can malfunction if exposed to water or dust, leading to communication failure. Conclusion     In conclusion, the waterproof and dustproof feature in two-way radios is crucial, especially in harsh environments. It is essential to consider the IP rating of a two-way radio before purchasing it to ensure it meets the waterproof and dustproof level for your intended purpose. If you are planning to use a two-way radio near water or dust, it is advisable to purchase one that meets the IPX7 or IPX8 rating for waterproofing and IP5X or IP6X rating for dustproofing. Always remember that a waterproof and d...

  • How can walkie talkies increase call distance?
    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...

  • 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.

  • 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.

  • How far is the actual communication distance of two way radio?
    How far is the actual communication distance of two way radio? on May 5,2023.
        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 ...
