SARL/AMSAT SA display receives award at Science Forum South Africa 



The SARL– AMSAT SA display at the Science Forum South Africa 2023 was awarded a special mention award for the best display and audience interaction. The award was presented at the closing ceremony of the forum on Friday afternoon. Hans van de Groenendaal ZS6AKV and Brian Jacobs ZS6YZ, who were responsible for developing and executing the display, received the framed certificate from the Dr Phil Mjwara, Director-General of the department of Science and Technology and Innovation. The forum at the CSIR convention centre was attended by over 4000 delegates.

The joint display, with the theme Science in Amateur Rado, featured the AMSAT SA dual band yagi antenna, a proto type of the AfriCUBE satellite, the SARL RF Noise monitoring system and the SARL two metre Karoo beacon project.

The RF noise monitoring system output was displayed on a large screen showing in real time the RF noise level at the convention centre.  It was significate to see the drop in the RF noise level at night when all the LED lighting and computers were switched off.

Brian Jacobs manned the stand full time assisted at various times by Hans van de Groenendaal, Cameron Eales , Koos Fick and Ruben Jansen van Rensburg.

The event was a worthwhile experience and a great opportunity to show that Amateur Radio is just not another hobby but a true technology pastime.

Interference from solar installations- As the South African public are realising that they are on their own and facing the many challenges of loads heading, self-generating electricity by households and businesses have become the norm. 

Generally, Radio Amateurs should not experience interference on HF or VHF from properly installed solar power installations but unfortunately it does occur when unqualified people do not install the system properly and use poor quality inverters and solar maximisers.

Often fitting ferrite beads and basic filters will solve the inference problem.

By design solar installations are not expected to radiate radio frequencies (RF) and cause interference as the necessary circuits suppress any RF radiation should be included in the design. There however are suppliers that will install equipment of inferior quality.  Solar installers are expected to issue COC’s, certificate of compliance, but these certificates generally only cover the electrical installation.

If a neighbour installs a solar system and it kills HF, there are two approaches. Point out to him or her that the installation is causing radio interference and that he should insist that his installer sorts out the problem. If that fails it is necessary  to send a written complaint with details of the interference to the manager of the local ICASA office. ICASA is fully quipped to do the necessary test and advise the owner of the installation to have the problem seen to or switch off his system.

The addresses of the local ICASA managers can be found on Please your copy your letter to the SARL at and Chris, ZS6GM at and keep the SARL informed of progress of the complaint.

What is Amateur Radio ? 

Tell me more  about Amateur Radio

Radio Amateurs, or "Hams" use two-way radio communication to make contact with other radio amateurs all over the world. They are even able to use satellites and on occasion speak with astronauts. Radio Hams can do this from home or while mobile in cars, boats or on foot.

Radio Hams have a full range or communication modes at their disposal. These include plain voice, Morse code, numerous digital computer modes and even graphical modes like television. As a licensed amateur radio operator you will be able to join in experiments using all these modes.

mateur radio can be enjoyed by young and old, male and female, even the most severely disabled can make friends around the world from their own home. This hobby knows no boundaries.
