This invention relates to an apparatus and method for receiving and automatically detecting the issuance of emergency, weather or other alert messages broadcast on a radio frequency, and recording that alert message into an alert receiver on solid state voice circuitry with a day and time stamp for later playback. This invention also teaches interface methods between the alert receiver and other communications systems whereby an alert message, or an alarm tone, is automatically relayed and repeated on the other communication system. A method and apparatus for automatically selecting the strongest received signal from a set of pre-selected channels, monitoring the selected channel for signal strength and the presence of modulated audio, and a sequence for automatically reinitiating the channel selection process, should certain preset minimum parameters for the received signal fail to be met, is also taught. A method and apparatus for selectively activating other communication systems for only those warnings of specific concern to certain users of the other communication system is also taught herein. A method and apparatus in which the alert receiver user can select the radio channel and the alert tone frequency and sequence to activate the alert receiver is also taught herein.
