A frequency-hopped spread-spectrum radio is of information that includes a pre-defined set of radios not considered adaptive because once programmed for and their relative positions. As an example, the radios a hop sequence, it is not changed.

DMR (Digital Modular Radio) A full SDR capable of interoperability with tactical systems such as HF, DAMA, HaveQuick, and SINCGARS, as well as data link coverage for Link 4A and Link 11. These systems are programmable and include software- defined cryptographic functions. The US Navy is committed to migrating DMR to SCA compliance to allow the use of JTRS JPO provided waveforms. The DMR may be reconfigured completely via on-site or remote programming over a dedicated LAN or wide area network (WAN). The four full-duplex programmable RF channels with coverage from 2.0 MHz to 2.0 GHz require no change in hardware to change waveforms or security. The system is controlled, either locally or across the network, by a Windows®-based HMI [23]. JTRS (Joint Tactical Radio System) A set of current radio procurements for fully SDRs. These radio systems are characterized by SCA compliance that specifies an operating environment that promotes waveform portability. The JTRS JPO is procuring more than 30 waveforms that will ultimately be executable on JTRS radio sets. System pa
