Designed to receive telephone and telegraph messages with the use of digital RF signals processing in MF-HF radio communication channels in the range of 0.1 to 30 MHz

The receiver is intended for use as part of automated HF radio stations operating in simplex and duplex adaptive modes. The receiver can be used as a stand-alone unit.
