The UK Radio Astronomy Association was established in 2008 as a registered charity (registration no 1123866) in the United Kingdom. UKRAA’s objectives are to promote the science of radio astronomy and all branches of radio astronomical research. Prior to UKRAA’s formation, British Astronomical Association’s Radio Astronomy Group (RAG) members had designed and built working protypes of a VLF Receiver and Magnetometer. UKRAA was set up to handle the manufacture and sale of these products and the production of technical manuals covering the use of the products and the background science.

Not For Profit

UKRAA is a not for profit business. Any surplus income funds the development of new products and our outreach activities. To keep our prices low UKRAA relies on the volunteers and Trustees giving their time. To date UKRAA has sold in excess of £46,000 of radio astronomy equipment.


Our primary activity is to supply equipment to amateur astronomers and other interested researchers. The design of new products and the manufacture of equipment for sale is all carried out by volunteers. To promote radio astronomy to amateur astronomers we give talks to local Astronomical Societies and amateur radio clubs and have provided support to schools and university departments on educational projects.


UKRAA needs new volunteers to help us develop new projects and to build and test our existing products. If you can contribute in these areas of expertise we would be delighted to hear from you:

  • Electronic assembly of through-hole and surface mount components. Experience with fault finding
    electronic circuits would be valuable
  • Expertise in the design of electronic circuits
  • Expertise in the design of electronic circuits
  • Software development in Python for the Raspberry Pi
  • Precision wood working to make up aerial kits and assembled aerials
  • Machining and mechanical assembly
