Project Overview

GNU Radio is a free software development toolkit that provides the signal processing runtime and processing blocks to implement software radios using readily-available, low-cost external RF hardware and commodity processors. It is widely used in hobbyist, academic and commercial environments to support wireless communications research as well as to implement real-world radio systems.

Release 3.7.3 and the WSR Hackfest

In case you missed the announcement, we've released version 3.7.3 of GNU Radio!

We're really pretty excited about this release. If you look at the news announcement or our changelog, you can see that we had many contributors to this release. It's also about a month overdue from our normal (though unspecified) timeline. But the result is something that we are really happy with.

One thing that strikes me with all of the contributions on this one is the amount people are really using GNU Radio for interesting stuff. They are testing all sorts of use cases, corner cases, and types of cases we don't yet have names for. Hard to find all of those issues without that kind of testing and use. So I feel good about the state of where we are with this version.

And then came the Workshop on Software Radio (WSR) in Karlsruhe. I presented two papers. The first was from Tim O'Shea and myself on our work on gr-benchmark and, and the second was on using our polyphase filterbank blocks in GNU Radio.

Following WSR, however, was our first European GNU Radio Hackfest. It was two and a half days and went brilliantly. Lots of fun, lots of good discussion, and lots of code written (and rewritten). There were a number of issues posted and pull requests made for new features or minor issues. In a way, it's a shame that some of these didn't make it into our 3.7.3 release, but we can't just keep waiting, so these will all make it into 3.7.4. I think we're just seeing a lot of interest and energy with the project and so we have to mark some time to get the releases out when we can.

We've logged our work from the hackfest as we always do. And I believe I have taken care of all issues and pull requests, so you'll find all the new (working and available stuff) already in the GNU Radio master branch.

Specifically, it was important to wrap up the loose ends of that hackfest as quickly as possible because we're heading right into our next hackfest at Ettus Research next week in California! So I expect more great stuff to come soon.
