What percentage of electronics sent to this country is tested by someone
here? Or are we
taking the word of the Chinese testers or the company with the contract
to build there?
Seems that the tip of the iceberg has melted on toys, food and other
imports that come
from China as to quality etc. And also what is actually being inspected
here by our own
inspectors, what few there are.
Almost every piece of electronic gear I have bought made in China in the
past few years
has caused interference of some type, either to my ham radio or even to
the TV itself.
Having worked with the Chinese since the late 80's and even lived
there, I can tell you
for a fact its much worse than what you can imagine. So dont expect
everything coming
from there to be compliant with any US standard, the only way is if the
American
contractor is standing there overlooking all processes. And some do..
most dont.

My 2000 model Sony multi-system TV was the predecessor of my HD set. I
was being driven crazy by noise on various ham bands. Then I noticed
one day while coming up the drive and listening to an AM broadcast
station, that the noise was coming from my own house. I sniffed around
and deterimed that the noise source was the switching supply in the Sony
set. Winding *all* of the AC line cord on a ferrite toroid eliminated
the noise.
Since then, I've found that manufacturers are cranking out gobs of
interference generators. One of the biggest sources encountered is the
switching supply which comes with those under counter halogen lights.
