ABSTRACT:
An RF radio and a method of monitoring warning alert data is provided. The RF radio includes a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting radio wave signal channels within AM and FM radio bands and radio wave signal channels within a weather band. The weather band is adapted to provide warning alert data. The radio also includes a controller for controlling the tuner to select a radio wave signal channel within the AM or FM radio band. The controller controls the tuner to periodically switch to the weather band to simultaneously monitor a plurality of weather band channels during an alternate frequency update, and determines presence of warning alert data. The controller further initiates receipt of the warning alert data when such warning alert data is determined to be present.
