Moduladores de FM (para LAD) em causa

Os adaptadores dos leitores de audio digital que utilizam o FM para se ouvirem nos carros estão em causa por uma denuncia da NPR que os acusa de prejudicar as suas emissões:

«The drama surrounding short-range, device-based FM transmitters is entering a new chapter, thanks to a recent complaint from National Public Radio. Bigger, commercialized radio stations are often higher on the dial, while public radio stations usually grab lower frequencies. That is the same range tapped by device-based transmitters, which broadcast across lower, unused frequencies. The technology is found within satellite radio receivers and other devices, and companies like Griffin Technology manufacture iPod add-ons that accomplish the same task. Now, the question is whether the transmitters are interfering with NPR broadcasts, and if so, what should be done about it. The public radio consortium has argued that a problem exists, and recently urged the Federal Communications Commission (FCC) to re-examine the matter. Earlier, the FCC subjected both XM Satellite Radio and Sirius Satellite Radio to a rigorous compliance process, resulting in numerous manufacturing holdups. According to National Public Radio chief executive Ken Stern, that process has not solved the issue of over-powered transmissions, and an "unchecked, growing problem" remains. Meanwhile, users of the technology can easily become frustrated by heavy interference, especially in more crowded urban areas.»
