At the just-concluded meetings, NAB Chief Technology Officer Kevin Gage presented a major engineering study about the policy options available to AM for dealing with issues such as increasing interference. The association is looking at everything, with the help of in-house NAB talent and outside consulting firm Hammett & Edison. Last year the NAB Radio Board authorized a special committee to study the problems of AM. Power lines, electrical devices and computers are all adding to the level of RF noise. The new NAB Labs operation will be focusing on AM, among other issues broadcasters care about. Some have proposed moving AM stations to recently-turned-in VHF spectrum, or expanding the FM band.
