The Digital Modular Radio (DMR), AN/USC-61(C), is the first software-defined radio to have become a communications system standard for the U.S. Military. The compact, multi-channel DMR provides multiple waveforms and multi-level information security for voice and data communications from the core of the network to the tactical edge. This video will show how the DMR continues to expand the boundaries of HF radio performance with HF Virtual Channel Exploitation and HF Dynamic Routing.
