When travelling outdoors，the purchase of walkie-talkies is very important. As we all know, the frequency of walkie-talkies is generally divided into U/V（ultra high frequency/very high frequency)range. Due to different frequencies, the former has strong penetrating power and is suitable for use in mountains, forests and cities, while the latter has a long transmission distance and is suitable ...
In the outdoors, walkie-talkies are in some cases more useful than mobile phones, as they do not require external base station support and can communicate freely with teammates in most harsh environments. In times of disaster, a GPS-enabled walkie-talkie can be used to send SOS signal. The theoretical frequency band of Frs walkie-talkies is in the range of 144-146 and 430-440MHz. In fact, the cent...
Amateur radio frequencies are allocated by the national telecommunication authorities. Each frequency differs in each location in every country depending on its bandlength. Frequencies in each city differ but some frequencies can reach multiple locations if it is strong enough. However, the International Telecommunication Union is the primary authority that manages the radio spectrum. This include...
How far can dual band radios communicate, 30 km? This is one of the most common questions asked by newcomers, but they often do not get a satisfactory answer. This is a complex question that requires a number of factors to be considered. Obstacles are a very important factor in communication distance. In the city, two handheld radios may only be able to talk for 1-2 km, whereas in open areas, they...
Dual standby: Dual band radios generally display two lines up and down, which are generally called the main channel and the secondary channel. When there is no signal coming, the main channel and the secondary channel are in standby mode. When there is a signal coming in, the walkie-talkie will choose the signal that comes first. When there is already a signal coming in, another signal cannot come...
Walkie-talkies are commonly used in underground parking lots in residential areas, shopping malls, and hotels. However, communication signals can be weak due to the underground location, which affects communication. How can we enhance the signal when using a walkie-talkie in an underground parking lot? In general, the reinforced concrete walls in the basement of residential buildings are quite thi...
DMR（Digital Mobile Radio）is a digital radio communication standard developed specifically for professional and commercial applications. On the other hand, analog radio refers to traditional radio systems that use analog signals for communication. So, can DMR radios communicate with analog radios? The short answer is no. DMR radios cannot directly communicate with analog radios because they u...
In today's modern society, having efficient and reliable communication tools is crucial for individuals and teams in various industries. Whether it's outdoor adventures, construction sites, or commercial operations, having a device that provides stable communication support is essential. The D2000Plus digital two-way radio, with its powerful features and reliable performance, successfully meets th...
