Decided on these radios and after testing I am very happy. I bought and used the long 18" antennas in order to increase the range and to conduct the range test. Ultimately I could get very good reception range of 3.5 miles with the power setting on 10 watts
was surprised at the quality, features and the functionality of the radios for the cost. So I guess you can say that they are good value and function pretty well.
These are pretty good quality for the price. One of my workers races trophy trucks and Class 1 buggies in Baja and he is familiar with these types of radios.
These radios are the real thing. A clean, 10-watt digital DMR signal
It's no Motorola but for the price it gets the job done just fine. I usually get about 3 miles of clear transmission with heavy interference from buildings or trees with just the base antennas.
These are amazing! Used at the lake and one person was at the cabin on top of a huge hill a mile long, and one was in the middle of the lake and they were clear as a bell.
Retevis is a great company to work with. These are good radios. Highly recommend Retevis. They are great !!!
they worked great. Occasionally these radios were used two days in a row without charging.
I use it for work and recreation. It works very well in the area where I live, three to four miles.
If you need a no frills brick of a radio, these will do. Can be programmed up to 10 watts transmitting power for a bit more penetration through the metal walls of a building
It's UHF both analog and digital and also great for basic GMRS usage between cars, on a Jeep trail or other. CPS is free from Retevis and a programming cable has came with every order.
this is one of the best general usage work radios Retevis puts out and hopefully they will continue to do so for a very long time.
