Could spell the doom for DAB radio. A bit of hash on FM could mean complete failure of the digital signal.

Even if these things sport a "CE" symbol*, I doubt many have been fully tested for compliance and as there is no control over the way they can be deployed and the wiring that they are plugged into, spurious emissions are a certainty.


*The CE symbol means the product has been rigorously tested for its possibility of interfering with other equipment and also its immunity from incoming interference. Applying a CE mark to non-complying equipment is an offence as is selling non-compliant equipment. Part of the work I do is the testing electronic equipment for compliance and writing up the reports, it's very onerous, detailed and expensive to do and requires much technical equipment and a special shielded room.
