Frequencies Supported

Medium Frequency (MF): 300-3000 kHz

Because medium frequencies afford stable transmission of radio waves over long distances, they are used primarily for medium wave broadcasting (AM radio), ship communications, LORAN (radio navigation), and other applications.

DKK has built medium wave radio broadcasting stations not only in Japan, but in many locations around the world. From site studies to design, manufacturing, installation, and maintenance, DKK provides end-to-end services for the construction of these broadcasting stations.
