The radio amateurs have known for a long time that PV installations (solar panels) could interfere. For more than 10 years, the VERON has been warning about the effects of equipment that emits unwanted RF emissions. That started with the Power Line Communication devices. This makes it easy to make an ethernet connection via the mains without having to install a UTP cable. Very popular with internet suppliers to connect a second television set at low costs. But it doesn’t stop there.There will also be PV installations (solar panels) whose converters and optimizers cause interference on our HF tires and even above that. All equipment is now equipped with switching power supplies up to our LED lighting. That has not gone unnoticed by the VERC’s EMC-EMF committee.
Agentschap Telecom comes with tips
Agentschap Telecom wants more insight into the causes and the prevention of interference by solar panels. That is why Agentschap Telecom has contacted various market parties. To come to solid solutions together. A number of tips can be found on the Telecom Agency website to prevent interference. Including the use of CE marketing approved PV installations, laying cables side by side, using ferrite etc. Read the full article on the website of Agentschap Telecom .
Interference due to solar panels in Amersfoort
Jaap PA3GYM had an unpleasant surprise in Amersfoort. Immediate neighbors placed solar panels on their roofs. The consequence; at Jaap, the signal strength meters of its receivers turned out to be full. He suffered a lot from interference . He asked the VERON EMC-EMF Commission for help . And a process from failure to solution was started. The VERON EMC-EMF Committee discussed these results with the AT during the frequent Amateur Consultation . The AT saw a good opportunity here to regard Jaap’s situation as a ” testing ground “. We save you all the details (which can be read via this link ). It’s about the result.And that was there (and can be admired via this link ). The interference was considerably reduced.
US Coast Guard warns about the use of LED lamps
On August 26, 2018, the VERON reports on the warning issued by the US Coast Guard about the use of LED lighting in shipping.The US Coast Guard says it has received reports from crew, ship owners, inspectors and other shipping related people. The messages concern poor reception on VHF radio, Digital Selective Calling (DSC) and Automatic Identification Systems (AIS).Problems with reception arise when this equipment is in the vicinity of LED lamps.
