Unfortunately, shortwave transmitters, the Earth's surface, and the ionosphere are dull and fuzzy tools for focusing broadcasting signals to specific distant listening audiences. by Important technological advance has taken place in the civilian space area, however, and further specific advances are reasonably, confidently expected.

and their expected performance have been presented, along with their estimated costs for global, high-capacity, small individual surface coverage area operations. Such a space-redated system-service would provide a received signal reliability and quality easily the equal of today's popular, local, over-the-air AM and FM audio surface broadcasting stations.

The UHF conceptual system would provide approximately 1,OOO full-time audio channels on a global basis, and serve 99.9 percent + of the world's population residing throughout 30 million square miles (8O million square kilometers)

of truly low cost receiver models thereby assured, particularly in lesser developed countries. If the cost of acquiring, maintaining, and operating the space segments were to be borne by the broadcasting governments alone, the cost could be apportioned to each to reflect that fraction of the service's capability (i.e., the product of its capacity, quality, coverage area, and time)

And any net revenues generated by use of the system for domestic broadcasting could be used to lower the cost of the worldwide broadcasting service even further. Finally, the availability of a new DBS-A service such as that outlined here, one that provides the same service characteristics as today's local AM and FM audio broadcasting but on a wide-area, low-cost basis, could prompt private interests to reach listening audiences in this new way, thereby providing additional private revenues to the system-service.
