摘要： A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

摘要： A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency during the pause. Fieldstrength, multipath, adjacent channel energy, frequency offset and FM modulation for the second frequency are measured. Tuning is switched from the second frequency to the first frequency. Tuning is switched from the first frequency to the second frequency dependent upon the measuring step.

摘要： A method of validating a signal received by a radio from a radio station includes determining a strength of the signal as received by the radio, ascertaining a frequency of the signal, and calculating a first distance between the radio and the radio station dependent upon the strength of the signal as received by the radio. A location and a broadcast range of the radio station are found in a database based on the frequency of the signal, A second distance between the radio and the radio station is computed based on a known location of the radio and the location of the radio station as found in the database. The radio station is validated only if the first distance and the second distance are within a margin of error and if the second distance is within the broadcast range of the radio station.

摘要： A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level.
