Providing a Home for a Lightning Sensor

The SARL Secretary was contacted by AfricaWeather, they are the largest privately owned weather company in Africa and have more than 24 lightning sensors around the country.

They are looking for people willing to provide a home for a sensor, all it requires is power and it is not very much power, the company will install and supply the SIM card for the sensor. For now, they are looking for hosts in Kimberley, Hopetown, Colesberg, Strydenburg, Vosburg, Prieska, Britstown and De Aar. Later the focus will be on the North-West Province.

AfricaWeather will offer free access to a high-level weather alerting web page to the Radio Amateur that successfully hosts this sensor. The webpage provides real-time lightning; Weather Satellite visualisation and a 7-day forecast. If you can host a lightening sensor in one of the towns mentioned, please contact Colin Morris, ZS6CPM at with a copy to

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.

In addition, two of W6IZT's NexGenRiBs will be operated remotely by a team of young amateurs. QSL via M0OXO's OQRS.

The Northern California DX Foundation has announced its financial support for the DXpedition, as it "features two important NCDXF interests, youth in DXpeditions and the RIB, Radio in a Box concept."

The NCDXF board has funded the DXpedition's request and added additional support for the two young operators joining the team on the island. The mission of NCDXF ( is to provide necessary financial support for well-organized DXpeditions to desirable DXCC Entities and to support advances in DXpeditioning skills, technology, and infrastructure.

Testing for Jarvis. As the N5J DXpedition to Jarvis Island will be challenged by both the season (especially on the low bands) and antenna restrictions, a series of preliminary tests will be conducted between 25 June and 25 July. This will include testing new antennas and the extended remote operator network from two locations:
* on 25 June-2 July, FW7JV (Wallis and Futuna) will be test the low band antennas (160, 80 and 40m) and a new 40/20m antenna;

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.

The Wacky 1W Challenge

17 June is international QRP day and South African operators are invited to test their QRP skills during this weekend. The Wacky 1W challenge takes place between 13:00 and 16:00 UTC on Sunday 16 June and aims to test operators' knowledge of effective antennas and operating procedures by limiting power levels and using distance to calculate scores instead of the number of contacts you make. A 5 W category has been included for those whose radios cannot reach 1 W. Results are grouped per power category and mode which creates the ideal opportunity for you to benchmark yourself against similar stations. For more information or to download the log sheet, visit the Challenge website at
