Just curious --- what kind of other mains-fed equipment is the noise

His sw radio receivers.

I don't that charging circuits can put noise on the lines, but I've
never noticed any effects from it & we have a lot of various DC
power supplies plugged in at the same time in our house.

But you don’t have a short waver radio receiver that you use much.
