[RFI] Bad noise on 2m band, only during day

The hourly plot looks like the output of a solar array.

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?


Thanks,
