bluesboy,
I'd say 'preferably not', and if you must, only under the same conditions that you're allowed the use of a computer. And only then if it has a CE marking. (If it hasn't, and
was obtained after Jan 1st 1996, its use is illegal in the EU anyway). The fact that it is a receiver doesn't prevent it radiating signals; the limits on those signals can be so minimal as to be laughable, depending on what the manufacturer decides in these days of self certification.
