G/VRC-140/E is a Software Defined Radio (SDR) in HF frequency band designed and manufactured according to the MIL-STD-141B standard. Modem of the radio meets the MIL-STD-188-110C for stability and increasing quality of voice/data transmission in HF frequency band. In addition, this radio is a frequency hopping radio to establish stable communication in EW situation. In order to keep away the operators from propagation center, the radio can be operated via a remote control unit as a panel. Output power of the radio is 150W. G/VRC-140/E is designed for installing inside a vehicle as well as stationary operation using the related power supply and various types of HF antennas. Using the ALE-3G capability, reliable/secure communication link can be established via the G/VRC- 140/E. Another capability of the system is frequency hopping for reaching reliability against Electronic Warfare.
