Radio amateurs know that sunspots affect VHF as well as HF propagation, and the solar cycle has a direct bearing on the prevalence of radio auroras, although the extent of this mode of propagation is not widely known. Radio Auroras sets out to explain this phenomenon in an easy to understand and useful way.

Radio Auroras tells the fascinating story of the radio amateurs who discovered this mode of propagation and how they made use of it. It includes details of how auroras are caused, how they can be forecast, and how best to use them to work DX. While auroras are often thought to be a VHF effect, this book also describes radio auroras at 28MHz as well as outlining the effects of auroras on the other HF bands. If you are interested in radio propagation or work DX on VHF, this is a must-have book.

Includes:

• How an aurora begins - the sun's part
  
• The magnetic fields of earth and sun
  
• How does an aurora come about?
  
• The problems of 'field-aligned propagation'
• Auroras on bands other than 2m
  
• Radio Auroras 2000-2012
