This report summarizes the development of various types of Alert receivers, operating in the standard broadcast band of 540 to 1600 kc. Ground rules for methods of operating a radioalert system were established in conjunction with OCD representatives. Four types of operation were selected. Three models each of these four receiver types were fabricated and tested. The total of 12 laboratory models were delivered to OCD. Test equipment suitable for demonstrating the two most promising receiver types was also assembled, and delivered to OCD. A preliminary analysis of the cost of mass producing the four types of Alert receivers was made. Accurate cost estimates cannot be provided until after a complete product design has been made. However, present indications are that three of the four types explored, if completely productdesigned for high-quality production, would cost under 10.00. Author
