128-channel radio receiver
It is a multichannel digital HF device with digital outputting of the received signals and remote control by means of the Ethernet interface (1000 BASE-T).
It is meant for being applied as a part of the automated assembles and radio communication centers. It provides the possibility of operating as a part of the digital phased arrays, and has a construction version for building in the 19-inch stand.
