“The Retevis RT52 may look quite familiar on the outside, it has the same dimensions and look as the Retevis’ RT3S dual band HT. In fact, just about every appearance between the RT3S and RT52 are identical. But the differences are apparent as soon as you turn on the radio radio. First off, you are greeted with a high contrast light colored text on a black screen. The second big difference of the RT 52 is the addition of dual Push to Talk operation.”
