[RFI] HF range solar panel RFI

[Dave Cole]

Ed,
A big thank you to you, and to the entire ARRL staff associated with 
helping reduce the RFI levels around the country!  You guys are an 
invaluable resource!

73s and thanks,

It also gives us the opportunity to take good work such as that done by Tony and get it into print, but also get it before industry.  Individual reports, including model numbers, are key to some of what we need to get done.

I wear my ARRL hat as the department manager of the ARRL Lab, but also serve on a number of IEEE and other industry committees, in a position of leadership. I serve on the ANSI accredited C63 EMC committee as the Chair of the subcommittee dealing with EMC immunity as well as serve the IEEE EMC Society Board of Directors as the EMC Society Vice President of Standards.  This liaison between the interests of Amateur Radio and professional industry opens doors for Amateur Radio that can result in resolution of problems.

I have a couple of screenshots that show how the noise is generated during the day, when the solar panels are illuminated by the sun and another that shows how the noise disappears after sundown when the panels are no longer energized.

No action was taken until February, 2017 (7 months later) when they attempted to fix the problem by changing out the Optimizers which actually made things worse.
