REDHAWK SDR software

If you’re into SDR then you have probably heard of GNURadio, gqrx, SDR# and other software tools for controlling RF hardware. With the growing popularity of the HackRF platform and RTL-SDR dongle a new software tool has entered the scene: REDHAWK.

As explained by its developers, “REDHAWK is a software-defined radio (SDR) framework designed to support the development, deployment, and management of real-time software radio applications. To support the design and development of software applications, REDHAWK provides tools that allow development and testing of software modules called “Components” and composition of Components into “Waveform Applications” that can be seamlessly deployed on a single computer or multiple network-enabled computers.

The REDHAWK integrated development environment (IDE) provides tools to support development of REDHAWK software. The development and deployment of REDHAWK Applications are aided by graphical editors and drag-and-drop Waveform construction. The IDE allows users to interact with and control multiple running REDHAWK instances and applications.”

REDHAWK is a Linux program suite consisting of the Core Framework, the IDE, and the Basic Components. The Core Framework is the software back-end of REDHAWK. The IDE is a Graphical User Interface (GUI) for development and use of REDHAWK systems. The Basic Components are building blocks that developers can use to create radio algorithms.

So far we’ve heard reports of REDHAWK working with RTL-SDR and with HackRF.

  1. This is interesting. Linux/Unix only. This looks sort-of like GNURadio but with the added twist that functional parts can be “cloned” not only withing a single system but across multiple systems. The concept is like seen with the Software Communications Architecture (SCA). SCA governs the structure and operation of the U.S. military’s Joint Tactical Radio System (JTRS):

    I could see this being a strong contender for something like a multi-receiver SDR, maybe with FPGA hardware having multiple DSP slices (e.g., Spartan-6?). Another application might be centralized deployment of a mesh network of SDR nodes.

    The IDE appears to be implemented in Java.

    1. > The IDE appears to be implemented in Java.

      IDE is not just “implemented in Java”, it’s based on Eclipse, which means it’s even more bloated than GNU Radio.

      1. Do you mean it’s using SWT? If it’s written as an Eclipse plug-in, then it’s not going to run on an ARM based processors, at least not as yet, since Eclipse has funny crashes on ARM based devices, probably owing to a dependency on Haswell generated binaries.

        Flash Light, on which fldigi is based, doesn’t seem to have these dependencies. Even so, an Eclipse based framework is intriguing, being a Java developer, and Eclipse being reasonably pervasive.

    1. GSk: I found these components that appear to provide the “glue” between the RedHawk world and the HackRF device (using its I/Q inputs) –

      RTL-SDR support in the Linux Kernel here –
      (The HackRF device can be treated as an osmocom-type input – at least in GNU Radio. You can see HackRF listed by name as “supported” on osmocom’s website, here –

      Serve up the I/Q data using rtl_tcp from here –

      From RedHawk, then, you can use a socket-read/write capability to collect the I/Q samples as a complex data stream.

      I have read, but have not heard, that one other possibility to glue the HackRF to RedHawk might be to re-use the GnuRadio OsmoSDR (gr-osmosdr) block in RedHawk (via GnuHawkintegration-gnuhawk).

      1. Will have to check that out, did not think HackRF had the equivalent of rtl_tcp. Perhaps some means exists to use as your propose.
