Hytera is the second largest manufacturer of two way radios in the world, and they seemed to have upped the game with their new OBR series of onsite business radios. There are two models currently available, the TC-310 OBR and the TC-518 OBR. These radios are compatible with the Motorola CLP, CLS, RDX and RM series radios, as well as the Kenwood ProTalk Series.
This unboxing video featuring Danny Feemster is a quick overview at the TC-310 OBR and some of its basic characteristics. It is available from Buy Two Way Radios.
