But:

the rotating prop can reflect RF, i.e. act as a radar reflector. Esp. props of aircraft are known for this. Back when I was styding in Rotterdam, I had a small B&W tv that used a whip antenna. I could detect a plane about one minute before I could hear the sound of the engine, by the interference pattern on the tv :-) I considered it my own little private radar set...

It might be an issue with windturbines, but since usually the blades are made out of wood or composite materials, unlike many a/c props of aluminium, I wouldn't worry about it.

We had a ham nextdoors who of course always got the blame when there was RF interference; even when he was on holiday. when I got into electronics & RF, whenever there was some interference on the telly, I'd know about it from my old folks. Usually when they yelled 'stop messing with our tv picture' I had to walk away from my desk, study book still in hand, wondering what was going on :-). And when the lights of our neighbours houses flickered, my dad usually got the blame because he was probably welding again... I was going to make a remark on human ignorance, but since I'm in the christmas mood, I won't pass judgement :-)

I have not noticed it on medium wave, it is due to the rectifier commutation. It should not affect neighbours as it only seems to travel a few yards. It is not too difficult to remove with a ferrite cored choke and a couple of capacitors if you happen to be in a part of the world that uses long wave radio.

If you don't use a metal prop there should be no other trouble.
