As a ham radio operator, this sort of thing is extremely common. Most cheap Chinese power supplies tend to broadcast a lot of noise.
Nowadays, it's mostly impossible to operate the short wave bands in a city due to all the static on the air. The regulation agencies have pretty much given up, save for the most egregious cases, due to how prolific the problem is.
It's pretty sad.

But no. The noise is omnipresent, and there's no way to escape it. https://apps.fcc.gov/edocs_public/attachmatch/DA-16-676A1_Rcd.pdf https://apps.fcc.gov/edocs_public/attachmatch/DA-16-676A1_Rc...
