Radio Astronomy & Technology Group

The recently formed Radio Astronomy and Technology Group aims to document and collate our technical journeys through various projects that are associated with Astronomy and Earth Sciences.

Many of our members have made or played with technology in order to achieve outcomes and we wish to pass on what we have done so that others can learn from our experiences.

The group's website is in 2 sections.

Radio Astronomy

Radio Astronomy only differs from traditional optical astronomy in that telescopes operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on natural radio emitting sources.

Although optical astronomers sometimes build their own telescope, it is not typical. However, the reverse can be said for the amateur Radio Astronomer as most, if not all the fun and challenge is in building custom equipment or modifying other equipment to do the job.

By using a number of radio receiving techniques, an astronomer has the opportunity for added mystery by making what is invisible to optical telescopes visible while listening to high energy interactions from distant celestial objects such as Pulsars or closer natural interactions within our earth's magnetic field, solar flares and other interesting noises from radio storms on Jupiter.

Since radio waves penetrate dust, some radio astronomers can study regions of the sky that are not visible to conventional optical telescopes, such as the dust-shrouded regions where stars and planets are born, and the centre of our own Galaxy the Milky Way.

The aims and objectives of the Radio Astronomy group are:

  • To facilitate and encourage the sharing of skills, ideas, techniques and knowledge resources to assist ASSA members in receiving radio emissions from space based sources.
  • To encourage an active forum for people who use receiver/scanner devices be they commercial ham radios, crystal sets or software defined radio and other types of digital signal processing equipment.
  • To provide support to the beginner and the more experienced in radio reception techniques and in using their own antennas, receivers, signal processing hardware and software.
  • To maintain a group whose activities are suitable for ASSA submissions/purposes and as a source of capable individuals to assist with other ASSA projects/initiatives.



Astronomy in general covers a lot of things, the internet and technology plays a big part in this, from finding out what the weather is going to be tonight, to remotely controlling your telescope or taking images, there is lots of technology involved as part of our 'hobby'

Many of our members make things for their telescopes and observatories, we document how and what we have done, but don't have a place to put that information, now we have a place! 

Some of our members monitor the environment, we take measurements of sky brightness, seeing and weather conditions at our observing sites. Some members have earthquake monitoring equipment in their observatories that is part of an Australia wide seismic network. 

Here you will find information on some of those projects consisting of Electronic, Mechanical and Software elements that are semi related to Astronomy or Earth Sciences

Information about technology members have played with that we think is interesting enough to document (and brag) about.

  • Be it a dew heater for optics, accurate timing for data recording, a 3D printed clip to tidy the cable clutter on scopes or some interesting software we've found ,hopefully, you'll eventually find it here.

The aims and objectives of the Technology group are:

  • To get Members to write up their projects with enough detail so that duplication by others is possible.
  • Create a repository for those documented projects.
  • Provide a place for technical information 
  • A place to put useful links.
