Amateur radio - version 2008

In this monthly feature Hans van de Groenendaal ZS6AKV, executive chairman of the South African Amateur Radio Development Trust (SAARDT)
looks at various technologies and activities that drive amateur radio. SAARDT is dedicated to the development of amateur radio in South Africa
with a special interest in the youth. The organisation is funded from donations and supports the South African Radio League and SA AMSAT.

puts forward amateur radio version 2008.
