The R&S®M3TR software defined radio family is a new generation of high-performance digital radios. It represents a revolutionary change, both technically and economically, in the tactical communications sector. The heart of the new integrated communications system is the lightweight R&S®MR300xH/U manpack transceiver (1.5 MHz to 108 MHz or 25 MHz to 512 MHz), which offers solutions for all aspects of tactical communications as well as uniform and reduced interservice logistics. A lightweight handheld version (R&S®MR3000P) complements the radio family. Like the manpack radios, the R&S®MR3000P supports both open and secure communications modes.
