Benefiting from the latest technologies, HRC-610/E a multi-band Software Defined Radio (SDR) is designed and manufactured for establishing radio communication in frequency range of 30~512 MHz. Different communication capabilities, supporting various modulation types, and wide frequency range lead to establishment of communication with various types of available radios in this frequency range. Due to frequency hopping capability and internal encryption unit with very complicated local ciphering algorithm, this radio provides a secure and reliable communication for the operator in the battlefield. Jamming the radio is very difficult because of its frequency hopping capability in a wide frequency range (30~512 MHz) as the main feature
