Tuning apparatus which is tunable to different broadcast frequencies and including a scale provided with indicia corresponding to such broadcast frequencies and a pointer movable across the scale to indicate the particular broadcast frequency to which the tuning apparatus is tuned. The pointer is supported by a movable support which is guided by a guide shaft. A plurality of markers are slidably guided along at least one guide rail and are individually settable to desired locations adjacent the scale, thereby representing particular broadcast frequencies to which the tuning apparatus is tunable. A key also is slidable along the guide shaft with the movable support, the key being selectively operative to engage a desired one of the markers to move the engaged marker therewith as the support is moved, whereby the marker is set to a desired position by reason of its engagement with the key. Tuning circuitry having a controllable oscillator for generating an oscillating signal whose frequency is variable and determinative of the broadcast frequency to which the tuning apparatus is tuned is enabled to produce an output representing received information when the movable support is moved to an aligned position with a respective one of the markers. Thus, the tuning apparatus can be rapidly tuned to any preset broadcast frequency as represented by the particular marker with which the pointer is aligned.
