All: Anyone have experience with Speed Queens 2018 front-load washers? Any RFI? Tony -K2MO _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.
Mike: Thanks for the link. It looks like both the top loader and front loader use variable speed motors so that could be problematic. Tony Sent from my iPad __________________________________________
All: I was wondering how the FCC measures the level of RFI emanating from a distant device to determine whether it's above or below FCC limitations? The reason I ask is that the RFI emanating from th
All: Solar Edge sent one of their engineers to inspect my neighbors solar panel installation that's been causing RFI since August of 2016. They tweaked the RFI suppression that was installed in July
Randy: They may have missed something so we're hoping they'll get it right the next time they come out. Should be in the next week or two. Thanks, Tony -K2MO On 9/3/2018 9:35 PM, Randy Standke wrote:

All. Solar Edge shut down my neighbors solar panel system this week which did have some effect. Because it didn't disappear completely, they now think the noise is being generated by another system i

This was a test Dave. I asked the engineers if they would do the entire system when they were here in October, but this is the route they chose. Will keep you posted. Tony -K2MO 73s and thanks, Dave

Jamie: If it's a SolarEdge system, you can expect to see a combination of close-spaced noise every 15 to 18 kHz with spikes every 200 kHz. The number of spikes increase as you get closer to the sourc
