SARL sets up a Spectrum and Technology Workgroup. With the publication of various Spectrum Policies and the imminent publication by ICASA of the equipment type approval policy, the Council of the SARL has decided to establish a Spectrum and Technology Workgroup which will be known by the acronym SARL STW.

The STW will coordinate the various previous initiatives such as the Technology Workgroup. The first tasks of the STW will be to develop a document to highlight opportunities for Amateur Radio in the recent gazetted Spectrum Policy for Economic Development. The STW will also coordinate the SARL’s participation in the SABS TC3 and TC74 EMC and Telecommunications technical committees, the WRC27 National Preparatory Workgroup (NPWG) and the IARU Region 1 EMC and Noise Monitoring (NMC) committees. Another task of the Spectrum and Technology Workgroup will be to set up technology webinars.

The STW is inviting interested SARL and AMSAT SA members with an interest in the technology issues confronting amateur radio to join the STW.

Here is a real opportunity for the younger generation to contribute to Amateur Radio’s future and to gain valuable personal experience. Send an email with your contact details and your area of interest to sarlstw@amateurradio.org.za

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 http://www.sarl.org.za/public/licences/licences.asp. Please your copy your letter to the SARL at secretary@sarl.org.za and Chris, ZS6GM at chris@crturner.net and keep the SARL informed of progress of the complaint.
