  • Abstract
    The lower radio frequencies are used in worldwide communications to a greater extent than is generally realized. This article discusses the almost-forgotten radio world that exists on frequencies below the United States´ standard AM broadcast band. The information is based on personal observations in Huntsville, Ala., of stations in the low-frequency spectrum.
