摘要
An Emergency Stereo FM Receiver designed to be part of a Homeland Security Emergency Radio System I envision. A receiver that would remain silent 24 hours a day, day after day, month after month, until an emergency transmission is broadcast by the Department of Homeland Security. A receiver that would take advantage of both the Left and Right channels of the stereo FM signal being transmitted. When turned ON and switched to the Left Stereo channel, the receiver would remain totally silent until the Department of Homeland Security transmits a Warning or Alert. When such a Warning is received, you could then switch to the right channel where you would receive more detailed local information from local authorities as to what is happening and instructions as to what you should do. I also envision additional circuits to improve reliability, as well as additional functions, such as lights to determine the current Alert Condition as well as digital modem capability, etc.
