SIX POSITION MEMORY TYPE UHF TUNER

The rotor shaft of a UHF tuner is spring biased by means of a torsion wire which extends longitudinally along the axis of the rotor shaft so that as the rotor shaft is rotated the wire is twisted. A rotatable memory turret is interconnected with the UHF tuner rotor shaft to provide UHF channel selection in any one of six positions of a main selector shaft. Indicator lights are selectively energized by means of a switching arrangement connected to the main selector shaft and a sensitive dial pointer arrangement is provided so that the operator may correlate a particular position of the main selector shaft with the particular UHF station which is being received. An AFC defeat switch is actuated each time the main selector shaft is moved to a different UHF channel position and is closed at all times when the main selector shaft is moved rearwardly for adjustment of the UHF rotor shaft to a new memory position.
