"No station shall retransmit programs or signals emanating from any type of radio station other than an amateur station, except propagation and weather forecast information intended for use by the general public and originated from United States Government stations and communications, including incidental music, originating on United States Government frequencies between a space shuttle and its associated Earth stations.   Prior approval for shuttle retransmissions must be obtained from the National Aeronautics and Space Administration.  Such retransmissions must be for the exclusive use of amateur operators.  Propagation, weather forecasts, and shuttle retransmissions may not be conducted on a regular basis, but only occasionally, as an incident of normal amateur radio communications."
