There was an experimental B.C. radio station working in Eberswalde from 1909 until 1938. This radio station was built and run by the enterprise C. Lorenz limited company. It was situated on the Finow chanel about one mile east from the center of Eberswalde. Main purposes of the research station were tests on the wireless transmission of voice and music. The emissions of chamber concerts taking place in 1923 and 1924 were very famous and had radio listeners in several European countries.
