Abstract: The present invention provides for an audio message broadcasting system which includes a source of pre-recorded audio messages such as a tape player for producing an audio signal of approximately one thousand cycles. The signal is delivered to a microwave transmitting station via available cable for transmission over microwave channels to a microwave receiving station. The microwave receiving station is connected to an earth based transmitting station for transmitting the signal on a 6 GHz frequency carrier to an earth orbiting spin stabilized geostationary satelite for receiving the signal. The satelite carries a wideband receiver which translates the 6 GHz carrier to a 4 GHz carrier for downward transmission of the signal. An additional earth based receiving station is located remote from the earth based transmitting station, such as across the continental United States.
