GSoC 2026: Coding stated
As of Monday, Google Summer of Code, 2026 edition, has been in its hot phase!
We’re proud to be able to mentor three students this year, which are, in alphabetical order,
GNU Radio 4: Community Stewardship and the Road to 4.0
Today, GNU Radio is reaffirming that GNU Radio 4 will continue as an officially community-maintained release line under the GNU Radio project’s established governance structure. Development will proceed from the current MIT-licensed core code base, and we encourage users and contributors to follow and participate through the official GNU Radio 4 repository.
First Release Candidate for GR4
GNU Radio 4.0 RC1: A New Foundation for High-Performance Signal Processing GNU Radio 4.0 has reached its first release candidate (RC1)—a major milestone that signals the transition from active development to near-production readiness. See the tag for all the details. At this stage, the core architecture is stable, the execution model is well-defined, and the API is no longer expected to undergo major breaking changes.
GNU Radio accepted for GSoC 2026
Hooray! GNU Radio has once again been accepted as a mentoring organization for Google Summer of Code 2026. This means that we will soon be accepting proposals from students/contributors who want to spend their summer hacking on GNU Radio. While we have updated our ideas list with projects ranging from GPU acceleration to GNU Radio 4 ports, we encourage you to propose your own project ideas!
SOURCE Magazine features GNU Radio
Enjoying Some Publicity You’ll find GNU Radio being featured in thousands of scientific publications, you can find it featured in books, university curricula, space, on railroad tracks and dedicated conferences on at least three continents. But frankly, I’ve been missing the time where I could venture out on the internet and just find someone just writing something about GNU Radio out of the sheer fun of bringing new concepts to people who would otherwise have missed a whole world of such things.
VOLK v3.3.0 release
Originally published on libvolk.org Hi everyone! This is the VOLK v3.3.0 release! We want to thank all contributors. This release wouldn’t have been possible without them. We received a lot of improvements to existing kernels, new kernels, and optimized support for a lot of existing kernels. Moreover, a lot more implementations make use of AVX512 now, as well as more optimizations for RISC-V, and more NEON implementations.
SigMF converter for MIDAS Blue recordings now part of sigmf-python
Bluefile Converter The SigMF leadership is excited to announce that the sigmf-python package Release v1.6.1 includes the addition of a converter for the MIDAS Blue and Platinum BLUE RF recording formats (commonly .cdif files). This allows you to seamlessly integrate BLUE file recordings into your SigMF workflows. The converter automatically detects BLUE file formats and can create standard SigMF file pairs, archives, or Non-Conforming Datasets (NCDs) that reference the original recording.
How GR4 Can Transform Your SDR Workflows
A New Chapter for GNU Radio Imagine a GNU Radio built for the future - a framework where your rapid prototypes seamlessly evolve into deployable, production-grade systems, and where AI-enabled SDR development feels effortless. It’s GNU Radio built to run in places once thought impossible. With GNU Radio 4 (GR4), that vision is becoming reality.
FOSDEM 2026 SDR/DSP Devroom – Call for Participation
Call for Participation: SDR/DSP Devroom at FOSDEM 2026 The Software Defined Radio / Digital Signal Processing (SDR/DSP) devroom is being organized for FOSDEM 2026, held in Brussels, Belgium, on Sunday, February 1, 2026. We are seeking contributions discussing free and open-source software (FOSS) for discrete-time digital signal processing and software-defined radio (SDR).
GRCon 2026 - Raleigh, NC, Sept 21-24
