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.
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).
Announcing GNU Radio Conference 2026 (GRCon26) - Raleigh, NC We’re excited to announce that GNU Radio Conference 2026 (GRCon26) will be held in person from September 21 – 24, 2026, in Raleigh, North Carolina!

Part of the value of our Block Doc pages is having an Example Flowgraph to show how that block can be used. In a recent review of our 555 current blocks, 214 of them do not have an Example Flowgraph! We’ve written a guide on How to Add an Example Flowgraph, and would appreciate if you could try it out!
We are excited to announce that GNU Radio Conference 2025 (GRCon25) will be run as an in-person event September 8-12 at the Edward Hansen Conference Center in Everett, WA (Greater Seattle Area). GRCon25 will celebrate and showcase the substantial and remarkable progress of GNU Radio and its usage in a diverse field of applications and industries.
Thank you, Jeff! It’s time for me to express my gratitude for Jeff Long (willcode4, if you find him online), who’s retiring from his role as the release manager and maintainer of GNU Radio. Jeff has been keeping the stable branches both stable and moving forward since March 2021 – a tiny bit of a Herculean task, considering that when he started to take care of GNU Radio’s releases, we we’re just hitting version 3.
New Textbook Featuring GNU Radio Published The GNU Radio community is excited to share the publication of a new textbook dedicated to GNU Radio and its applications! Communication Systems Engineering with GNU Radio: A Hands-on Approach explores a wide range of topics, including RADAR, GNSS reception, satellite communication, and digital communications.
Greetings GNU Radio Community! We wanted to take a moment to look back on all the awesome things that have gone on in this incredible community over the past year, some of which we may not have been so great at making everyone aware - there’s our first New Year’s Resolution!
Attention all GNU Radio enthusiasts, Software Defined Radio (SDR) developers, and radio frequency experts! Join ADI as we get ready for GRCon24, where we’ll dive into the world of SDR. The conference will be full of knowledge and innovation, featuring sessions and demos that will reshape how you think about SDR technology.
