I find it hard to believe that you can sell an electronic product that has that poor a behavior (it's emitting that much RF noise); this is the sort of hardware that really ought to be clamped down on, hard. RF Spectra is a shared resource, and a rather limited one, and it only takes one careless neighbor with poor electronic equipment to wreak havoc on other devices. If this lawnmower is getting used in the U.S. I would really like to see the FCC pay this manufacturer a visit.
