Equipment / Re: Noise around the house

I live in a small block of flats & over the years I have noticed more noise on the LF & HF bands. Some of the threats could be HDTVs, wi-fi routers & any unregulated electronics bought online. An example is from around 8500 kHz to 12000 kHz I can see a very high noise floor on my SDR which is there 24/7. When I go outside to the small garden outside my block of flats with my portables the noise is still there. I know they have changed some of the street lighting in the vicinity from the amber type to the white ones which I presume are supposed to be more economical, & around then I noticed more noise although whether that is the cause I don't know.
But it is not only on the lower bands I get noise, I have noticed more starting to appear on the FM band as well. Sometimes I see random noise spikes lasting a few minutes from 65 to around 95 MHz. Again, I can get the same noise outdoors with my portable radios. One suggestion for the cause are solar panels which I am seeing more of on top of buildings in my neighbourhood & further down the road. It seems analogue radio really is at threat from new technologies.
