The Open Source Radio Telescopes Project is a resource for radio astronomy telescope construction at any level, from simple feed horns to phased-array feeds and interferometers. Please get involved! Our main site, with more formalized content, is We want to get your contributions!

Discussion Forums

We want your input, and encourage everyone to contribute to our Discussion Forums.

Telescope Designs

Evan and Sophie enjoying some observations of our Galaxy

Radio Telescopes can be almost any shape and size, from a single wire to a gigantic structure 100's of meters in diameter. This Open Source Radio Telescope site is a place where students and scientists share their experiences with building telescopes. The first few designs, below, are horn antennas, each with its own unique features. Take a look at these designs, then build your own, that is just a little better!

  • Alexander - an HI horn antenna constructed by the First2Network
Students observing with Alexander, the Telescope they created in Summer 2017
  • Bessie - another HI horn antenna constructed by the First2Network

Please document your improvements here.

LightWork Memo Series

The LightWork Memo Series is an informal series of numbered memoranda on topics related to Citizen Science with Radio Telescopes.

This series is intended to encourage the public in the United States, and throughout the world, to collaborate on the design, construction and operation of Radio Telescopes for the purpose of furthering science, engineering and education. LightWork memos series guidelines are described in Memo 0. The creation of a memo series is motivated by the success that a focused memo series can have on organizing design and construction of large astronomical facilities.

The memo series title has two implications. The first is that this memo series concerns Work with radio wavelength Light. The second is that we envision that those developing the radio telescopes will grow a large collaboration, making a significant contribution to the worlds understanding of the universe. Many hands make LightWork.

The first and latest memos are listed below. Please update this section when adding new memos to the LightWork Memo series.

A number of organizations provide telescopes for sale. Jeffrey M. Lichtman (Ham call sign KI4GIY) sells very sensitive receiver systems. RADIO ASTRONOMY SUPPLIES Phone: 954 554-3739

The Canadian Centre for Experimental Radio Astronomy is dedicated to providing open-source software and resources for radio telescope designs. Visit CCERA here:

The Society of Amateur Radio Astronomers (SARA) is another great resource for radio telescope building and amateur radio in general. The members are knowledgeable and experienced amateur radio astronomers, and have much to offer on this topic. Check out their website to see what projects they're involved in:

Gnu Radio Software Introduction

Sophie, Evan and Glen have put together some videos showing the basics of GNU Radio. These video tutorials introduce building a simple GnuRadio programs and producing audio spectra. These videos show simple, fun, examples you can build yourself in a few minutes.
