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.
