@profoundlynerdy@mastodon.technology Thats an exageration and ignorant of the situation.
For starters it isnt the panels that cause the interference, its the inverters, and yes some have been known to be a problem. That's largely because people use cheap chinese imports that havent passed FCC testing, and they tend to be noisy.
That said its not all setups, not even most setups, but it does happen. When it happens hams can and often do report it and hopefully the FCC will step in and force the person to use a properly certified inverter.
Needless to say the idea that it will make shortwave unusable is complete nonsense. I know many operators who have large solar panel installations who have never experienced any issues.
@freemo @profoundlynerdy recently purchased a German inverter ( avoid Chinese inverters). To get very low interference you need to have your radio within 2m of the inverter.
