A weather radio adapted to automatically select a preferred channel of operation.
A receiver is coupled to a signal quality circuit that outputs signal quality parameters.
A controller is coupled to control the frequency of reception of the receiver and
is coupled to receive the signal quality parameters. A memory is used to store
several signal quality values, and is coupled to the controller. When the controller
receives a stimulus, it controls the receiver to sequentially receive all the weather
radio frequencies of reception and store a signal quality value for each. The controller
subsequently controls the receiver to receive one of the frequencies of operation
based upon a comparison of the stored values to select a preferred one of them.
The radio is therefore programmed to receive the preferred channel and monitor
NOAA Weather Radio transmissions for the local FIPS codes and other weather alert messages.
