VRC-411/E system is a direct sequence spread spectrum radio designed and manufactured for establishing communication in the UHF1 frequency band. Due to the method used in this radio i.e. expanding the frequency spectrum in a wider bandwidth and decreasing power level of transmitter and as a result hiding radio signal under the noise level, the signal is prevented from monitoring by enemy for eavesdropping and jamming. A keypad included handset is designed for the radio to set the system parameters and establishing voice communication. In addition, parameters of the system can be set via the GUI software.
