The world calling Africa

  Once a year radio amateurs from all over the world turn their attention to Africa to participate in the Africa All Mode International DX Contest. The objective of this all mode contest is to focus the world on African radio amateurs. Contesting is one of the many facets of  radio amateurs and challenges their operating […]

Help build a knowledge economy by supporting science projects

  The Minister of Science and Technology, Naledi Pandor, often speaks about the importance of building a knowledge economy for South Africa and that public-private partnerships are required to achieve this. There are many opportunities for companies to direct a small percentage of their social responsibility or marketing budgets to help build the foundation of […]

The WRC15 agrees on 5 MHz amateur allocation

  At the World Radiocommunication Conference 2015 (WRC15) radio amateurs were allocated a small segment in the 5 MHz band from 5351,5 to 5366,5 kHz on a secondary basis after years of preparation, trials and discussions. The conference modified the table of allocations based in Article 5 of the ITU Radio Regulation by introducing a […]

Man-made pollution of radio spectrum is a growing problem

Man-made pollution of the radio spectrum is a growing problem for everyone, with radio amateurs being the first to notice its effects. The main reason is that radio amateurs work mostly with low power transmissions and weak signals which are particularly susceptible to man-made noise. In a recent editorial, Dave Sumner, CEO of the American […]

SA AMSAT CubeSat project on track

  SA AMSAT has successfully completed the first prototype of the various elements of its CubeSat project, named Kletskous. The CubeSat is being designed and built by radio amateurs and will ultimately include a 20 kHz linear transponder, extensive telemetry and command systems and selected school science projects. Kletskous measures 10 x 10x 10 cm […]

With industry support amateur radio can make engineering cool

  It is unlikely to be a coincidence that worldwide, the countries that have large electronics industries also have the largest number of  amateur radio “hams”; for example the USA, Korea and Japan. Amateur radio is the oldest scientific hobby in the world. It started with the invention of, as it was called in the […]

Bloemfontein 5 MHz beacon enhances the SARL propagation research project

  The South African Radio League (SARL) propagation research project is based on a number of automated beacons using a program called “Weak Signal Propagation Reporter” (WSPR). During July 2015 the scope of the project was greatly enhanced when a beacon was installed in Bloemfontein. For the past few months the focus was on short […]

ISS astronaut answers questions from SA learners

  It was a day they will long remember!  Learners from the Sol Plaatje primary school in Mmbatho linked up with the Italian astronaut Samantha Cristoforetti  on the International Space Station (ISS) via a link established  by an radio amateur ground station on Saturday 2 May 2015. Commander Cristoforetti is spending almost six months on […]

SARL to launch 160 m propagation research project

  For many years radio amateurs have shown interest in the propagation properties of the various frequency bands available to them. One of them is the 160 m band where some interesting propagation properties have been observed. It has recently come back into focus as the sunspot cycle is on its downward slope to a […]
