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.


During last week ICASA issued licence renewals for the 2023/24 licence year. Unfortunately, the notification to renew was sent out prematurely. At the time, the increase in fees had not been populated in the ICASA system and any invoice issued would have reflected an incorrect fee. The Authority therefore closed the renewal process. Any renewals paid on these notifications will be honoured by ICASA.

Licensees will receive another notification at the beginning of February in order for the renewal process to proceed. That annual increase is 6.9% and will be as follows: The fee for a one-year licence increases from R 166.00 to R 177.00; a two-year licence increases from R 317.00 to R 338.00; a three-year licence increases from R 455.00 to R 485.00; a four-year licence increases from R 579.00 to R 618.00 and a five-year licence increases from R 692.00 to R 738.00.

It is important to note that renewals need to be paid before Saturday 1 April 2023 as unpaid licences will expire after this date.

CW Operators - 21 May 2023 


This activity takes place between Saturday 27 May and Saturday 3 June 2023. There is no specific start or ending time. Your task is to order parts and build just one Radio, parts can come from different Amateurs, but it could happen that other amateurs do not have the items you are looking for. Also note that band conditions, the weather, QSB, QRM or an Eskom black-out could be a challenge.

Therefore, your aim is to have all the parts in one place within seven days, giving you time to accommodate the unforeseen anomalies just indicated. Parts ordered from other amateurs, must be shown in the comments section of the community logger. To be added to the logger you need a password, please e-mail Eddie, ZS6BNE at for that. E-mail Mike, ZS6MSW at for the parts list you will need. Happy shopping via CW.


Hierdie aktiwiteit vind plaas tussen Saterdag 27 Mei en Saterdag 3 Junie 2023. Daar is geen spesifieke begin- of eindtyd nie. Jou taak is om onderdele te bestel en net een radio te bou, onderdele kan van verskillende amateurs kom, maar dit kan gebeur dat ander amateurs nie die items het waarna jy soek nie. Let ook daarop dat band-toestande, die weer, QSB, QRM of 'n Eskom-kragonderbrekings 'n uitdaging kan wees.

Daarom is jou doel om al die onderdele binne sewe dae op een plek te hê, wat jou tyd gee om die onvoorsiene afwykings wat so pas aangedui is, te akkommodeer. Onderdele wat by ander amateurs bestel word, moet in die kommentaar afdeling van die gemeenskap-logboek gewys word. Om by die logboek gevoeg te word, benodig jy 'n wagwoord, e-pos asseblief vir Eddie, ZS6BNE by daarvoor. E-pos Mike, ZS6MSW by vir die onderdele lys wat jy benodig. Lekker inkopies via GG.

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.
