FOSDEM 2027: Amateur Radio DevRoom

The Amateur Radio devroom at FOSDEM 2027brings together the people who write, use and take apart free and open-source radio software and hardware: SDR developers, radio amateurs and satellite experimenters. If you have built, measured or reverse engineered something that involves radio waves, we want to hear about it.

Amateur Radio (ham radio) is a radio service defined in international regulations, and a worldwide community that has been experimenting in the open for over a century. It combines electronics, software, propagation and human contact, and it remains one of the few frameworks in which individuals can design, build and operate their own transmitters.

Satellite links are no longer the preserve of agencies and operators. With commodity SDR hardware and free software, anyone can capture, dissect and understand what LEO constellations and geostationary payloads are transmitting, and put those signals to uses their designers never had in mind. We want talks that open the black box: how the waveform works, how you figured it out, and what you built with it.

Topics:

  • New developments in amateur radio modes
  • Software tooling for amateur radio operators
  • Free and open radio hardware
  • Satellite communication systems: open-source modems, waveforms and protocol stacks, ground station software and networks
  • LEO constellations seen from the ground: signal capture, analysis and reverse engineering of downlinks
  • Signals of opportunity: using satellite signals for things they were never designed for (positioning and timing, passive radar, reflectometry, ionospheric and propagation sensing)
  • Creative reuse of space and ground infrastructure: amateur transponders, repurposed consumer terminals and dishes, low-cost receive chains
  • VLF systems, radio astronomy, propagation monitoring
  • Entertaining wireless hacks

How to submit ?

Submit your proposal at https://​pretalx​.fosdem​.org/fosdem-2027​/cfp: choose “Submit a proposal” and select the Amateur-Radiotrack.

  • Submission deadline: 23/11/2026
  • Notification of acceptance:01/12/2026 – Schedule published one week later
  • Devroom date:Sunday 31/01/2027 morning, Brussels
  • Short talk:25 minutes slot, including 5 minutes of Q&A

What we are looking for:

This is a technical community conference. We want to see how your project works, what was hard and what you learned. Live demos and prototypes are very welcome alongside slides. Marketing-style presentations will not be accepted, and talks must relate to free and open-source software or open hardware.

All talks are recorded and streamed live. By submitting, you agree to your talk being published under the same licence as all FOSDEM content (CC BY).

The final schedule will be published on the FOSDEM website. All times are Brussels local time (CET, UTC+1).

IARU Region 1 Clarification Regarding Recent Legal Proceedings in Belarus

Following reports regarding the prosecution of radio operators in Belarus, IARU Region 1 issues the following statement to clarify the distinction between amateur radio activities and individual legal compliance :

1. The Scope of Amateur RadioAmateur radio is a technical, educational, and service-oriented hobby defined internationally by the ITU and governed by national regulations. Its purpose is the self-training, intercommunication, and technical investigation carried out by amateurs — that is, duly authorised persons interested in radio technique solely with a personal aim and without pecuniary interest.

2. Accountability and the LawWhile the individuals involved in this case hold amateur radio licenses, our investigation indicates that the actions leading to their prosecution fall entirely outside the scope of the amateur radio service. An amateur radio license grants the privilege to experiment with technology and communicate within specific parameters; it does not grant immunity from national laws, nor does it authorise the use of radio equipment for activities that contravene the legal framework of a sovereign state.

3. Distinguishing the Hobby from the ActionWe believe the public narrative surrounding this case has been somewhat misplaced. The core issue is not the practice of amateur radio itself, but rather a failure to comply with specific national laws. It is vital to distinguish between the legitimate use of amateur frequencies and actions that are unrelated to the technical and social goals of our community.

4. Our PositionIARU Region 1 does not condone or support any actions by licensed operators that bypass legal requirements or violate the terms of their amateur license. We advocate for the protection of our spectrum and the rights of our members, but this advocacy is predicated on the “Amateur Code” — which dictates that an operator must be balanced, loyal, and law-abiding.

The amateur radio community is built on a foundation of international cooperation and respect for regulation. We urge our members to remember that the integrity of our hobby depends on our collective commitment to operating within the legal boundaries of our respective countries.

We will continue to monitor the situation, but we reiterate that the legal consequences faced by individuals for actions outside the scope of their license are a matter for the relevant judicial systems.

Dave Court EI3IO SK

It is with great sadness that the International Amateur Radio Union (IARU) marks the passing of David Court, EI3IO, in July 2025.

David was a leading figure in international spectrum management on behalf of the amateur service, bringing decades of technical and regulatory experience to his volunteer work at the highest levels of global telecommunications governance.

David served on the IARU Region 1 Executive Committee and was a key contributor to IARU’s presence in the International Telecommunication Union (ITU) and regional telecommunication organizations (RTOs) such as CEPT. His working experience spanned multiple ITU World Radiocommunication Conference (WRC) cycles, where ultimately he represented the amateur and amateur-satellite services with clarity, rigour, and strategic foresight.

A meticulous and highly informed delegate, David played a central role in the preparation and coordination of IARU positions for ITU Study Groups, Working Parties, Conference Preparatory Meetings, and WRCs. His leadership was particularly critical in advancing amateur access to the 50 MHz band,culminating in the successful outcome at WRC-19, where a 6‑meter allocation was approved on a secondary basis in many countries.

David’s professional background in telecommunications policy and regulation provided a solid foundation for his effectiveness in international forums. He was widely respected by administrations and fellow delegates alike for his command of detail, his diplomatic approach to technical discussions, and his unwavering commitment to the amateur services.

Among his many contributions:

  • 50 MHz (6 m): David was instrumental in IARU’s engagement in the lead-up to WRC-19 Agenda Item 1.1, helping to secure a Region 1 allocation that aligned with existing usage in Regions 2 and 3. His technical input and regulatory diplomacy were crucial to building consensus among CEPT members.
  • Spectrum defence: He consistently advocated for the protection of amateur HF bands against proposed sharing or reallocation, providing clear and evidence-based input on interference risk, propagation, and service characteristics.
  • RTO engagement: David built strong relationships within CEPT and ITU‑R, ensuring that the amateur perspective was effectively voiced in preparatory and working groups.

Beyond his formal roles, David was a mentor and advisor to many within the IARU structure. He brought continuity, institutional memory, and a practical understanding of how to navigate the complexities of multilateral decision-making — always with the objective of preserving and advancing the interests of the amateur community.

In recognition of his exceptional service, David was awarded the IARU Region 1 Medal in 2020. This honour reflects his leadership and dedication during the critical period of the WRC‑19 process and his broader contributions to the Region’s spectrum advocacy.

David Court, EI3IO, leaves a legacy defined by deep technical insight, regulatory acumen, and an enduring belief in the value of amateur radio as a scientific, educational, and public service resource. His contributions will resonate through future generations of spectrum advocates and radio amateurs.

The IARU offers its sincere condolences to David’s family and friends. He will be greatly missed — both professionally and personally — by the global amateur radio and regulatory community.
