You're right! Little of this stuff gets tested and the "self
certifications" are a joke. Here is one of many articles about XM and
Sirius converters that put their signals on 88.1-88.9 MHz so you can pick it
up on your car radio. Three quarters of the units tested violated FCC Part
15 regulations with one of the units testing at over 200 times the legal
signal level!

The problem caused many people who were listening to classical music or news
on NPR/non-commercial stations in their cars to suddenly find themselves
listening to Howard Stern being transmitted from a nearby car!

Subject: Re: [TenTec] OT: RFI from Plasma TV?
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.
