OARC - Online Amateur Radio Community

Contributor : OARC - Online Amateur Radio Community

The Online Amateur Radio Community (OARC) is a dynamic UK-based radio club that operates entirely online, bringing together hundreds of amateur radio operators, learners and technologists from across the globe onto a unified platform. Built around a vibrant Discord server, OARC fosters a uniquely inclusive and collaborative environment where radio enthusiasts from complete beginners to licensed experts can share knowledge, build technical skills and push the boundaries of modern amateur radio. 

OARC is also best known for running one of the largest online amateur radio training programs in the UK, offering structured courses via Zoom to help members progress from Foundation to Intermediate and Full licences. These training sessions are backed by an extensive community wiki, technical workshops and 24/7 peer support, enabling members to learn not only the theory but also the practical applications of radio operation. 

Beyond education, OARC has become a hub for cutting-edge community-driven radio infrastructure, including its ADS-B aggregation network - a system that collects real-time aircraft position data from contributors worldwide and its HFDL monitoring initiative, which captures long-distance aviation messages transmitted over high-frequency bands. 

By participating in this global infrastructure, I’ve been able to combine my interests in signal processing, RF engineering, and systems integration to contribute meaningfully to a shared ecosystem of open knowledge. OARC represents the best of amateur radio: community, collaboration and a shared passion for understanding the invisible signals that connect our world.

As part of this global network, I’m proud to be OARC’s sole contributor from India, hosting both my ADS-B and HFDL receiver node from my home station in Hyderabad. My setup fills a crucial data coverage gap across South Asia, feeding regional aircraft positions and HF telemetry into OARC’s live aggregation network. This contribution not only improves global aviation tracking accuracy but also supports radio science, data visualization and experimentation within the amateur radio community.
