One of the weird noises(sounds like a howling wind starting right down in the noise and building till it peeks and then fades back into the noise) I get on HF especially on 40m metres although I have heard it on the other frequencies as well, many a theory has been banded around the radio club including ground radar from Manchester Airport as I am only +/- 2miles from the start of Runway 2 and they have a Mahoosive radar dish at the start of the Taxi way.
I see similar signals in various places, and I've always assumed that it's local noise from some dodgy power adapter or something similar. I did a test recently where I turned off all the power to house and pretty much all of this type of noise vanished (I posted the results here somewhere). That said, even then there was still noise from the laptop and even internal noise from the rtlsdr dongle I was using!
