ABSTRACT:
A continuously variable UHF tuner arrangement is provided wherein a single channel selector shaft is provided with a detent position for each of the seventy UHF television stations and a highly accurate detent mechanism is employed to return the channel selector shaft to any one of said detent positions with extreme accuracy. As a result, the tuning elements of the UHF tuner may be accurately aligned to different UHF stations corresponding to said detent positions and a nonambiguous digital dial arrangement is employed to indicate to the operator exactly which UHF station is being received. A masking member concentric with the selector shaft is provided with a viewing area in which only one member from cooperating tens and units dial members is simultaneously visible.
