ID-51 PLUS2 description :

The ICOM ID-51A PLUS2 (ICOM ID-51E PLUS2) is a VHF/UHF dual bander and has digital/FM dual mode functions. Please note that "PLUS2" adds Terminal and Access Point modes to the original ID-51 PLUS device. The handheld makes not only conventional FM local calls, but also D-STAR calls through a repeater network connected worldwide, or calls over an Internet gateway. With this ICOM you can call a friend in another city, or even internationally through a D-STAR repeater, with digital clear audio. In addition the transceiver can send digital voice with data: text messages, GPS position information, pictures. The DR (D-STAR Repeater) function makes communication simple. By only selecting a destination call-sign in "To", and a nearby repeater in "From", you can talk with other D-STAR users. The call is automatically routed to the repeater destination the called user last accessed. Call-sign routing enables you to call a selected person wherever they are. In addition, using the reflector function, you can talk through several repeaters at once.
