摘要： A method of configuring a tuner includes scanning at least one range of radio frequencies, measuring a signal quality metric for each of a plurality of the frequencies, and selecting a set of operational frequencies for the tuner. The selecting step is dependent upon the measuring step.

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.
