Hello everyone, I'm trying to chase this bad noise that I receive from 
my shack.

I have a fairly sized yagi on 144 and I can hear this noise coming from 
a certain direction.

So I left an RTL-SDR on for some hours and I found that the noise is 
higher during day (high temperature? low humidity?) and almost 
disappears during night.

Here it is some spectrum:


And also an hourly plot:


Before going around with my car, can you recognize this kind of noise 
and give me some hints?
