Many countries in Europe make the manufacturer responsible to fix a device
that is experiencing RFI. Among others my old country Sweden. I wonder whats
the reason they never made the manufacturers responsible on this continent?
Probably money? These days the general idea on this side of the pond is to
blame somebody else. Nobody takes responsibility for their own actions
anymore. That's probably why we have the highest number of lawyers per
capita in the world. That's my 2 cents!
Merry Christmas and Happy New Year!

Subject: Re: [RFI] Low voltage lighting solid state "transformers"
The point is that it is NOT illegal to sell a device that meets the emission
standards. It is only illegal to operate it in a way that causes
interference. There's a big difference. The burden is on the USER to
resolve the issue, not the manufacturer. The FCC won't fine the seller for
the device, but could fine the user of the device. In my case, since I am
the one that owned the device and it only interfered with me then the FCC
won't do anything to make the manufacturer fix it. If the device were owned
by my neighbor, the FCC could make the user stop using the device but they
won't tell the manufacturer to stop selling it since it meets the emission
standards.
Likewise, TV manufacturers are not required to fix TVI problems. The user
gets the shaft. That's the biggest problem with Part 15 rules:
the manufacturers have no responsibility to fix or replace equipment unless
is it violates emission standards. That means that the typical ham neighbor
gets the shaft. What is my neighbor supposed to do when his TV picks up TVI
from my LEGALLY OPERATING station? Call the TV manufacturer? Yeah, right.
Name one television manufacturer that has ever replaced or fixed a device
that was experiencing TVI?
