Please come prepared to help us work out the remaining pieces to get to the 4.0.0 release.  We need help across block development, applications, examples, testing, documentation, and release readiness.

Also, the board wrote a statement last week about the importance of this community and stewardship of GR4 as the next evolution of the GNU Radio project.  So please take a look if you haven't already:

GSoC '26: Introduction and Project Kick-off

Hello everyone,

My name is Youssef, and I am very pleased to share that my project, "Graphical interoperability between CyberEther and GNU Radio", was accepted for GSoC26. I am incredibly excited about this opportunity.

I am relatively new to the RF and SDR world, but I have been learning a great deal over the past month. I have been meeting weekly with my mentors, Luigi and Håkon, during the community bonding period to discuss the project architecture and get up to speed.

I am very grateful to be a part of this community. Hopefully, by the end of the summer, I will have successfully integrated CyberEther's GPU-accelerated sinks into GNU Radio.

The official coding period starts today, and I will document my progress on a blog. I will set it up this week and share the link over at Matrix, would be very happy to receive any feedback from you all.

Best regards,
Youssef Mahmoud

Re: Difference between GR4 on fairacc vs gnuradio org

Hi Zaky,

We would recommend contributions including issues and PRs going to the gnuradio/gnuradio4 version.

Hi, just curious, what is the difference between these ? I see them getting synced, but let's say someone wants to create a new issue/PR, where should it be landed ?

volunteer opportunity -> IAC2026

Hi Everyone, I'm heading up OUTLYR Space - a non-profit foundation aiming to be a Global Space Agency. We're working on a space network concept (using GNU Radio), and our 2nd paper was accepted at iac2026.org this year. I'm looking for volunteer help (min 4 hr/week) to complete testing by early October; no pay but you'll be a co-author, and free trip/stay/registration at the conference in Turkey for up to three contributors :). Send me a note if you're interested,  thanks for reading! Ralph https://outlyr.space
