bad noise on radios on 2 meters

https://apps.dtic.mil/sti/pdfs/ADA580765.pdf (Table 5)
These guys checked the length of the wind turbine blade, then calculated it's resonant frequency and multiples it may emit or reflect RF at. Might be revealing to use an RTL-SDR and SDR# free software on a laptop and point a portable yagi at these things. If you're an optimist, there may be frequencies in the spectrum halfway between multiples of the resonant frequency they don't emit or reflect RF at.

Might be relevant if the blades were conductive metal, but they are usually carbon fibre and any relationship to a 1/2 wavelength of RF is nonexistent.
 
I feel your pain brother.

Been dealing with S8 to S9 noise during daylight hours from a shitt* installation of solar panels. As soon as it gets dark noise is gone. Been going on for 13 months now. This past Summer I did speak to the home owner, and he just said OK, but never did anything about it.

I do know for a fact cable companies amplifiers can obliterate 11 meter AM too, and the noise is constant day and night. Went round and round with the cable company to fix it.

The malfunctioning cable amplifier was about one block from my house. I finally got the problem fixed when I told them it was leaking RF on the aircraft channels. Airplanes go across my house all the time to the airport that is about 1.5 miles from me as the crow flies. While riding around in his van, the cable tech used a leak detector to find all the leaks. He even stopped by the house, and fixed a small leak on the line running to my house.

It seems to never end.

I'm thinking carbon fibers come in varying levels of electrical conductivity depending on how they're made. Certainly not a great antenna material. I've heard of guys having antenna issues when using carbon fiber as masts but have no experience first hand. For all I know there's a ground wire or wire mesh inside the thing they forgot to deal with or something. Part of the grift may be to purchase any of the many system parts from China and not GE so who knows for sure. Maybe a rough neck forgot to set a ground connection somewhere.
The guys who build these things would certainly be a better source of information than some corporate moron in an office.

its not the blades,they been operating almost a year now but im thinking its got something to do with the controller electronics
 
That's my thought too.....something with the inverters they use to convert the DC into AC.
yes the blade pitch,headhouse turn,brake is all on command from1 centrally located tower and if a few wires are loose bad connectiion, noise be bad because these are 300 feet up to the headhouse.at that height noise can travel far i think

Looks like blades made of fiberglass over a balsa wood frame are pretty common.
1 of those blades on a tower near me is coming apart. last saturday on our drive to grocery store wife said whats that white piece flying? watched it fall,turned in n examined it. a layer of frp about 3 ft square. looks to be about the same composition of sides in frp semi trailers.
 
@Rwb you made a comment at one time not too long ago about the Eagles that had nests in your area - are these towers piled in to the fields - are these towers more crowded together now?

How have the Eagles and the wildlife fared this winter - er, what are they doing now?

they stay about a mile away from them. my pair that lights in my yard was there 1 day never to return. i miss seeing them.both would set in the dead tree in my yard n watch us walk around never disturbing us or them. noise must run them away
 
captain killowatt,you won this 1. last week a local am broadcast statioin came out and drove around. next day they called n said if it persists call them.
the very next day a pickup was driving around. it had a small antenna on top looked kinda like small tv antenna.
the suspected wind tower been shut off ever since that pickup did the tour.
today they had a big thing hanging off the tower. had lots of wires on it. my pictures dont show them like my bosch and lomb does. pictures are taken from about 3/8 mile away

So has your noise problem been reduced any since that turbine has been shutdown?
