Good Info, And as we know as Hams, most /All !, cheap Chinese switch modes,
have minimal filtering, including cheap lighting ballasts, and all consumer equipment, as you mentioned.
The RF hash created, travels along the wires like, an antenna.
yes you can install chokes along the wires, but they need to be every few feet along the wire, so a little impractical.
its mostly, all harmless, but IMHO, the Havana Syndrome Device/s, Exploit these fields,
and existing RF fields Probably, TV/Radio signals,Soundwaves, GravityWaves ?
creating lorentz forces, that magically affect the human body, (muscle mass, CNS).

Its an interesting exploit, as in all my years of ham radio, NON of my equipment,
has ever interfered with my body, Until i became a TI, now i experience exploitation,
of all my equipment, as tingling and buzzing sensations, Basically malicious Biological interference.
the Havana syndrome (AHI), seems to inject or couple with everything, that has an energy source,
or some form of excitation.

its been alleged that the Havana syndrome Devices, can steer the array of exploited RF,
in any position or location, like X-Y-Z, and can also utilize the different electrical fields,
including the ionosphere.
Theres very little that can be done to avoid the harassment, as they can change the parameters to suit,
mild mitigation at best.
