Many people ask us how long the communication range of Retevis Walkie Talkies, so we decide to take a communication range test about some digital radio of Retevis.

Last week, we take some models (RT3,RT8,RT81.RT82) of Retevis Digital Walkie Talkies to do sea level and mountaintop communication range test. Also we get the test location from RT8 Gps Version.

Sea level Test, we begin from a Seaside town called “ YangMeiK” in shenzhen to “Shuangyuewan” which located in another city HuiZhou, around 35km.  RT23 and RT3 can reach to 13.6km,but RT8 can get clear call to 19km, where RT81 and RT82 also can reach accompanied by some noise. See below report：

Mountaintop test. We tested this 5 radios on different mounts in shenzhen city.

Wutong Mount altitude：943m ,  Geographical coordinates ： 114°11′55″~114°14′45″E、22°33′30″~22°34′48″N

Qiniang Mount altitude:869m  Geographical coordinates：114°26′00′′~114°37′20′′E，22°27′00”~22°36′20′N
