For those ( RFI Engineers, etc ) that want to learn more about RF EMI at all
frequencies from these Solar Array and Inverters
look at this link, very interesting See link below

Well, this Solar Array was put up with a City Permit and I requested the Permit
& Info
to be able to identify the Company, Installer & Owner.
Will see if any of my RFI measurements, Waterfalls, and Times for On and Off
make any
sense.
The family that has the array has kids, work for an Aerospace Company, so I
think Grow Lights
are not the issue.
I think the Slow Data is a PLC Power Line Controller & Conditioner for the
8.048MHz and associated
Carriers, etc
I will reconfirm with AA6PX on his Mag Loop Findings and also look below the MW
Band as well
Only an AC Inverter could make this Racket tied to the AC mains that can be
heard 6 blocks away.
Once I find the Solar Company Name, Installer, I can find more about it's
features
Been working with the ARRL Technical Specialist here in Southern California and
those
within ARRL Headquarters.
My situation is very well documented with Times, Video's Google Maps, Bearing's
in Direction Finding studies,
etc ( 8 Band Spectral Plots with Water Fall Plots and more ( Mapping
Intensities at Power Poles within 6 blocks
of RFI source as well.).
Been careful not to jump to conclusions - since saying fire in a Movie House
when there is no smoke
can led to no one to listen to you later when there is actually a real fire !!!
My next step is with Solar Company, then Installer and then Property Owner
I knew walking into this mess would not be easy, may need ARRL Legal & FCC if
Solar Company does not
respond.

Been fighting an RFI problem since early Jan 2017
These New Solar Installations are destroying the
HF Bands Big Time here in California.
It’s Happens to be verified by an RFI Engineer who is also a ham
AA6PX that as working with Gary Lopes - WA6MEM
Watch this Video
https://www.youtube.com/watch?v=k7jXBDX19JQ
Noise come on at Night for 12 Hour On/ !@Hour Off Cycle
What should be my next step ?????
ARRL - FCC- AC Power Company
Help !!!

*************************************************
Interference to Licensed Radio Station by the
FCC Primary User Radio Station WB6DJI
finally located
*************************************************
Interference came on 1st week of Jan 2017 when this Solar
Array was installed to see back Power to SCE Southern
California Edison.
Never seen this much RFI in my 40 years on the HF Bands
Need FCC Help - ARRL Help - Edison Help
Distance of Maximum RFI is about 600 feet North from
this Location - WB6DJI
Can be heard for 2 blocks South along Anza Ave and
Marjorie Avenue along SCE street Light lines
Very Bad Interference ( RFI Carrier strongest at 8.048MHz )
with Carriers ( Slow Data Rate Modulation ) in Amateur
Radio Bands ( See Video's )
Interference started 1st week of Jan 2017 and continues
Interference Onto SCE AC Power Mains / telephone Lines and
Radiates through out RF HF Licensed Spectrum Band
Used Magnetic Loop Antenna and Bearings from two 45 degree
positions cross over New Solar Array on Neighbors Garage about
8 house's from my location. This was done by an RFI Engineer
in my Area.
The RFI get into AC Power and Telephone Lines.
Very strong and gets most of the HF Bands
Can hear 8.048MHz Signal 6 blocks away along street
light power lines in my area
Location of Solar Panel Installation finally located
21318 Anza Avenue, Torrance, California. 90503
Started on an 18Hour On / 6 Hour Off, then on 2-21-2017
Interference comes on at 11:04pm Nightly and
turns Off at 11:03am Daily as of 2-27-2017
Same Strong Carriers with Data in 8MHz Band from 8.084
from 8.1MHz thru 8.4MHz and 12MHz Band
Violates Part 15 FCC regulations for Interference
to a Primary FCC Licensed Station in this Frequency
Spectrum by a Consumer Electronics Device
