RF radio and method for monitoring multiple channels to acquire warning alert data
First Claim
1. An RF radio having a radio band configured to receive warning alert data, said radio comprising:
- a radio receiver for receiving broadcast radio wave signals;
a tuner adjustable for selecting radio wave signal channels within first radio band and radio wave signal channels within a second radio band, wherein the second radio band comprises a plurality of channels adapted to provide warning alert data; and
a controller for controlling the tuner to select a radio wave signal channel within the first radio band, wherein the controller controls the tuner to periodically switch to the second radio band to simultaneously monitor the plurality of channels in the second radio band and determine presence of warning alert data on one or more of the plurality of channels in the second radio band, and wherein the controller initiates receipt of the warning alert data when the warning alert data is determined to be present.

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.
