Wait till we start getting stuff made in "Inja" as the Brits like to
call it.

The two largest offenders in this home are:
1) The new appliances - all contain Chinese switchers that came
through Customs as a 'component'. And....., FCC specifically
exempts home appliances from any regulations regarding RFI ! ! !
Must have a good lobby in Cangress?
2) My ISP, Jab Broadband, or what ever they are called these days
(localy Rise Broadband). I've aggressively loaded their line
from the dish to the radio room with massive amounts of ferrites
and done a responsible job of terminating the shielding on
the CAT 6 cable. Can't totally reduce them to the noise floor on
HF or low VHF (I play radio astronomy as well as amateur
radio).

Although you seem to be targeting imports from China, they come in from
all over the world with many as components. Currently because of taxes,
parts from Europe tend to cost more so the impetus is to purchase cheap
elsewhere.
Save 10 cents here and there in computer power supplies and with millions
sold, ea 10 cents saved can quickly add up to millions of dollars. TV
sets. computers, networks, and so on. I counted an easy 10 to 12 wall
warts here in the den depending on what I'm running. Modem (1), Router(1),
Telephone(1), servers (2), USB drives (2)(can be 4 or 5), assorted
accessories (2 to 4 more).
It seems like everything comes, powered by a wall wart. At least my
wireless headset is powered by USB from the computer.
"So far" with 5 computers, and 2 smart TVs on a CAT5 Gigabyte network
along with numerous laptops, tablets, and smartphones, on wifi I've had no
interference from "MY" stuff. I did have something running S9 that was
between 60 and 120 degrees that "appeared" to be at least a mile away. It
was just a strong white noise that fell off rapidly around 60 and 120
degrees. For frequency it fell off between 15 and 20 meters on one end and
above the 6-meter band on the other. I haven't heard it in a couple of
years. About the time the local hams got serious, it disappeared.
It hasn't been many decades since we complained about Japan, then Korea,
then China. Whose next as the noise floor continues to climb? Right now
(4:15 AM) the noise floor on 40 is between S1 and S2 on the FTDX5000 with 1
preamp. There's too much junk in front of the rig to adjust much of
anything. There will always be someone on the horizon who will build
cheaper and sell for less.
In many cases it's American companies buying and assembling cheap,
imported junk. We were the originators of planned obsolescence. I had a
car in the late 60s or early 70s that had the right front quarter panel
rust out before the car was a year old. The manufacturer offered to pay
half the cost of fixing and painting. I had a custom shop do it for less
than that and I trusted their work.
