And thanks for what you do, too, Dave. At some point, I think we need to try
to bring ARRL's RFI web pages and yours into closer agreement. Our cooperative
program with FCC may not be perfect, especially with some of our complainants
who tend to thrash about and keep getting everyone working at cross purposes,
or get so inflamed that they burn the house down, but it makes a difference and
we use it to build more and more collaboration, with FCC and the industry.
And the reason that ARRL has the resources to devote full time engineering
staff to do this is that 160,000 of you all chipped in! Remember that always.
(With thanks to all who offer their support for this work.) Heck, I am still
doing this work for free now, just a bit less of it, and NONE of the
administrivia! LOL!

Subject: Re: [RFI] LED Street lights - Locations of Noisy Systems?
Hi Ed,
I worked with the city engineer here a decade ago, and found almost
nothing from the LED lights they were testing. They were testing
various models of lights, and gave me the locations and pole numbers of
each type. I sat under each one at light startup...
Sitting under any of them, with an SDR, at start time, yielded almost no
RFI, 3-30 MHz.
Thankfully the city uses metal poles, and does grounding on the pole,
and the electrical system. I am very lucky-- the city, the electric
company, and the cable company, all run tight ships here.
On another note, the ARRL, sent a letter to a grower I located via the
SDR setup, and the RFI problem ended within a month. That was about 6
months ago, and the RFI has not returned. All I can say is THANK YOU!
I have 80-20 meters back! That saved me the FCC work involved, and was
a wonderful solution.
I have now probably now doomed myself, and the RFI will begin again this
evening!
In any case, THANK YOU and the ARRL for all you do for RFI!
73, and thanks,
Dave (NK7Z)

I am not quite geared up yet to make mobile measurements, but do have the
equipment and can go out into the field and make some calibrated measurements.
I haven't followed every post of every topic on this list (gasp!), so does
anyone know of a noisy LED street-light system within a couple hundred miles of
central Connecticut? I will go there and report back what I find.
