The same frequency is the premise that two walkie-talkie scan talk. If they are not on the same frequency, even walkie-talkies of the same brand and model cannot talk; if the frequency is the same, even walkie-talkies that are not of the same brand can talk. So it matters. Generally speaking, there are two types of handheld radios: a professional walkie-talkie, and an amateur walkie-talkie, which ...
There are many intercoms on the market that claim to be 10km intercoms, 50km intercoms, 100km, 500km or even 1000km intercoms, but when you actually use them you will find that the data may have to be cut in half.As we all know, high power walkie talkies can make the communication distance longer, which can reach 5-15 KM or even further in the suburbs. So,what is the reason for the shortening of t...
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 impression of many people, the walkie-talkie is generally the image of "stupid, black and rough", and our requirements for it are often reliable and durable. It seems that such products have nothing to do with technology.However, with the rapid spread of intelligent digital communication technology, walkie-talkies are becoming more and more technological, such as POC radios we are talking a...
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...

GMRS is easy to use and doesn't require programming, making it the perfect radio service for anyone. First of all you need to know what GMRS is. General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around...
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...
