Online SDR Training Now Live!

Hello SDR Fans!

It’s been a long-time goal of ours to put our SDR training online in an on-demand format, so that people around the world could learn SDR at any time. That’s finally started happening! Our first class is online, and we’re working on the second right now. After that, are more to come.

We broke up our content into chunks roughly one day in length, though they will likely run a bit longer than that. Our first course, for example, has over 7 hours of video. Given the time it will take you to work through the projects, this will be more than a day for nearly everyone.

While the on-demand format is new, the material is very similar to what we’ve been teaching for years to private customers and at conferences such as Black Hat and the Wild West Hackin’ Fest. The main difference is that a few of the hardware projects required some changes so you can complete them in a virtual setting. We’ll do these projects in a simulation mode, but we’ll demonstrate all of the things you’ll need to do to make them work in the real world. We’ve also simplified the process of getting GNU Radio running on your system by providing you with a virtual machine containing all of the software and project files you’ll need.

We will also be offering a new in-person class consisting almost entirely of hardware projects, as a companion to these online classes. The companion class will provide hand-on training with SDR hardware and live signals, while the online classes will allow you to do most of your training at your own pace. Stay tuned for details on that.

We hope the chance to learn SDR in a more flexible (and distanced) way is useful to you. If so, please check us out!

SDR Training in Seattle

Hello readers! Until now, our schedule has only allowed time for SDR training at customer sites or at conferences such as Black Hat and the Wild West Hackinfest. After many requests, we’re finally able to offer an open class, where individual students can sign up and learn the ins and outs of Software Defined Radio.

As always, these are small class sizes full of intensive, hands-on learning. They’ll be held in the greater Seattle area (the suburb of Kirkland to be specific) from the 5th to the 8th of November. First will be our Intro to SDR class, then our Intermediate Digital class. If there’s enough demand, we’ll add on our Reverse Engineering and Python+gnuradio classes (email us if you’re interested).

You can register here, and if you sign up on or before the 3rd of October, you’ll get a discounted rate.

If you have any questions about the classes, please contact me at paul<at>

See you there!

New SDR Courses!

After learning to build analog and digital radios, a number of our customers had the perfectly reasonable question: “What next?” Over the last year, we’ve developed two additional SDR courses that provide an answer.

The first course focuses on reverse engineering RF devices with SDR, with a host of practical exercises and real hardware to attack.

The second shows you how to build SDR-based radio applications, focusing on the especially tricky part of programmatically extracting data from gnuradio flowgraph objects. Getting data out of flowgraphs is a problem that stymies a number of folks, but I’ll save you a ton of time by showing you powerful methods to get this done cleanly.

As with our previous courses, we first taught them to carefully chosen lead customers. Now, after numerous improvements and tweaks, they’re ready for primetime.

You can contact us at if you’d like to arrange a private training for your organization. We are also planning on two public training sessions this year: one in the greater DC area and a second in Seattle.
