Respectfully, has everyone reporting RFI to the FCC done their homework? Please don't get the idea I am criticizing here, I am not, just adding a bit more information to the discussion.

Things added to your RFI log like everyone you have spoken too, what you said, what they said, their names, signal reports, any recordings, the exact process used to pin things down to the location etc., presented to the FCC in clean, clear written form. Anything less than that and the process slows...

I had a few issues with grow operations over the years, and the FCC has been johnny-on-the spot to send a letter(s) to the offender(s). In both cases, the issue resolved instantly after the letter.

I spent a lot of time in each case documenting every step, (around a year on one case), doing everything as if it were going to court, (which thankfully it did not), treating every step like I was at work, not doing my hobby... In short being as unemotional as possible, and as professional as possible.

The expectation is on us as Amateur Operators to document things in a way the FCC can use. Neither the FCC, or the ARRL is going to do this for us.

It may not be right, and it may not be how all of us want it, but it is the way it is... If you want action from the FCC you have to make it easy for the FCC to enforce.

Again, I am not criticizing anyone, or anything that has happened here, just offering some thoughts.

73s and thanks,
Dave

Well, it appears there is no authority.  These companies have the free run to do what ever 
they want and nobody is going to stop them except bad publicity and that is not easy unless 
it’s airbag failures in automobiles, even then it’s  going to take a long time 
for resolutions.

This is sort of like anything goes.  Nobody is in charge.

Good luck.

I have a S9 + noise level across the entire VHF band caused by a solaredge 
installation. I haven't looked at HF yet but I'm not sure I want to.

Part 15 seems really clear but that doesn't seem to make any difference to 
solar Edge.

If I am recalling correctly, the Fcc does not include any specifications for radiated 
emissions below 30 mhz and leave it to "well engineering practice."  But that 
is never defined.

Wondering what they are going to knock down from S9+40 to what, nothing or 
something less than?

Also wondering if the FCC is kept informed of this?

Your spectrum plots look just like SolarEdge RFI does.

I just met with a SolarEdge engineer.  His contact information is Tefford Reed 
<Tefford.Reed@solaredge.com <mailto:Tefford.Reed@solaredge.com>>.  They are 
working on several houses surrounding a ham in Poway, CA (who has S9 +40dB RFI from the new 
SolarEdge systems that just went in near him).  They plan to correct the SolarEdge 
installations near me in two weeks.  It is great to finally see some activity from them.  
Tefford told me to ask hams with SolarEdge RFI to contact him.

Randy:
In this case the solar panels could be covered with dark tarps to stop
their interference.  They can stay covered until SolarEdge comes out
and fixes that system. Randy KQ6RS

The tarp solution should work. My neighbors SolarEge system goes quiet at night 
when the panels are inactive. The attached screenshots show the difference 
between the daytime RFI noise level and the nighttime noise level.
