UKRAA promotes the science of radio astronomy and all branches of radio astronomical research by designing, manufacturing and selling radio astronomy equipment for amateur astronomers.

Both are available to down load below.

The UKRAA Magnetometer

Introduction to Radio Astronomy

The first article covers the use of the UKRAA Magnetometer and
encourages amateur astronomers to have a go and observe the earths
magnetism. John Cook (Director BAA Radio Astronomy Section) and Andrew
Thomas (UKRAA Trustee) describe the operation of the magnetometer 
sensor and consider the practicalities of making observations. This
article was first published in Radio Astronomy the Journal of the
Society of Amateur Radio Astronomers (SARA) Journal, Nov-Dec 2020, pp.

The second article is an introduction to radio astronomy for a general
readership. It was published in the February edition Radio User Magazine
and aims to interest the reader in radio astronomy and give guidance to
some introductory projects.

The editors of both magazines are keen to receive articles for
publication and can be contacted through their websites
