ABSTRACT:
An improved system for indicating a tuned broadcast band frequency in which a rotatable turret projects a beam of illumination along a predetermined path towards a dial scale with marking indicia indicating a selected band frequency. A carriage operative to move in a linear path tunes a predetermined band frequency as selected by an operator. The carriage engages a pivotable line on said turret so as to rotate the turret on its axis to project the light beam on the dial scale at a band frequency corresponding to the position of the carriage.
