The Society of Amateur Radio Astronomers (SARA) is an international non-profit organization. The society provides a collaborative environment for radio astronomers at all levels.
The members have developed radio telescopes and have detected galactic hydrogen, masers, pulsars and even fast radio bursts.
The society holds two online meetings a month. One discusses everything technical about building and maintaining radio telescopes. The second shows practical observations and techniques to observe with various radio telescopes.
The society holds two world-wide conferences per year where members brief the latest in radio astronomy design and builds.
The society, also publishes the journal Radio Astronomy, with an issue every 2 months.
