TV set interference issues, in BBC land...
 

Here's a BBC story regarding TV-set-generated interference taking revenge on the new wireless upstart.

You can swing that two ways:

-Older electronics are electrically less clean than modern electronics when it comes to (presumably) forcing noise back upstream on the AC line or EMI shielding.

-Modern electronics (and supposedly telecommunication equipment) are so cost reduced that they cannot handle abnormal line or environmental conditions.

I tend to disagree with the first statement from all the noisy switch mode supplies in modern gear.... but then again "old TV" in the vernacular these days includes switch mode supply sets 70s and newer.

This story was incomplete. The whole village is served by DSL, which is much more susceptible to interference than a broadband coax cable system.

That still isn't "the rest of the story." It's a crap explanation to say that DSL is more susceptible to interference. That mere fact alone doesn't mean anything.

For starters we need to understand if it was conducted or radiated noise. Also, for all we know there might be some other intermediate object that was indirectly responsible for a perceived cause-and-effect relationship.

As an aside, Ars Technica is as good of a source for accurate technical information as People Magazine is for hard-hitting investigative journalism.
