Open Source Radio Telescopes Electronics Kits

Build a neutral hydrogen radio telescope! Make your own map of the Milky Way! Detect sudden ionospheric disturbances by monitoring submarine communication signals!

If you would like to receive one of the following kits, send a one-page email to Richard Prestage (richard.prestage _at_ explaining why you are interested in it.

The Open Source Radio Telescopes is a new educational program which aims to inspire students (learners) of all ages and backgrounds to pursue their STEM (science, technology, engineering and mathematics) interests by providing them hands-on opportunities to construct and observe with simple radio telescopes. OSRT makes open source software, instructions, and curricula available online (see ).

At the GNU Radio Conference 2018 GNU Radio Educators Breakout Session, we will be giving away free HI Horn Antenna Electronics Kits. These are a $300 value, but more importantly includes the most sensitive (we think) room temperature Low Noise Amplifier available, which you cannot get anywhere else. The kit will have full instructions, and is everything you need to make a complete radio telescope, apart from the general hardware (available from any hardware store) and a computer to run the GNU Radio software.

In addition, we will have ten Small Loop Antenna kits available. These are even simpler to build, and you can use them to detect Sudden Ionospheric Disturbances by monitoring their impact on ELF submarine communication signals.

The horn antenna kits are generously made available by the West Virginia University Center for Gravitational Waves and Cosmology and the West Virginia University Digital Signal Processing in Radio Astronomy programs.

The small loop antenna kits are generously made available by the Green Bank Observatory.
