SO1048 TUNING APPARATUS WITH BAND-SELECTION MEANS ABSTRACT OF THE DISCLOSURE Tuning apparatus of the type including at least first and second tuners, such as AM and FM tuners, operable to be tuned over respective broadcast frequency bands. The tuning apparatus includes a dial scale calibrated in at least two sets of gradations to represent the particular frequencies in the respective frequency bands to which the tuners are tuned and an indicator movable across the scale to indicate the frequency to which a respective tuner is tuned. The apparatus comprises at least one first settable element associated with a corresponding frequency band to be set to a desired location along the scale and at least one second settable element associated with a different frequency band to be set to a desired location along the scale. Sensors are coupled to and movable with the indicator to sense each of the first and second settable elements as the indicator is moved across the scale. A control signal generator generates a respective control signal when the indicator is positioned such that the sensors sense a corresponding one of the settable elements. An output is derived from a respective one of the tuners when a control signal is generated corresponding to the sensing of a particular one of the settable elements. -i-
