Why This Matters

This open-source 240-antenna array revolutionizes space communication by making Earth-Moon-Earth (EME) signal bouncing accessible to more enthusiasts and researchers. It lowers the barriers of cost and complexity, fostering innovation and experimentation in the tech and amateur radio communities. This development could accelerate advancements in satellite and deep-space communication technologies.

Key Takeaways

Open-source phased array simplifies space communication for amateurs.
Reduces costs and technical barriers associated with traditional large antennas.
Encourages innovation and experimentation in space and radio tech.

A New Frontier for Ham Radio

Bouncing signals off the Moon—known as Earth-Moon-Earth (EME) communication—has long been the ultimate challenge for radio amateurs. It required large antennas, expensive equipment, and accurate manual pointing and tracking. We try to bring this down to Earth, providing all the tools needed to experience the thrill of space communication, with an open source software-defined phased array.
