Abstract :
The problem of polluting our skies extends beyond man´s senses; our ether is becoming ensnarled with electromagnetic emanations. The situation has become critical and, if our technology is not to mire in a morass of radio signals, something will have to be done to quiet the confusion. Some systems by nature of their operation must pick their inputs from the airwaves. But there are a host of others that can do just as well¿if not better ¿ linked directly to a transmitter. Thus, many receivers now operating, and envisaged for future operation, will be phased to cable operation.
