Abstract
Methods, systems, and apparatuses for selecting alternate channels for broadcast radio channels, and for tracking alternate channel selections, are provided. Some radio systems provide alternate frequencies for tuned radio frequencies to use when the tuned radio frequency signal is no longer receivable. In aspects of the present invention, historical information is generated from alternate channel switching attempts. In further aspects, the generated historical information is used to aid in making a subsequent switch to an alternate channel.
