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 70 UHF television stations and a highly accurate detent mechanism is employed to return the channel selector shaft to any one of the detent positions with extreme accuracy. As a result, the tuning elements of the tuner may be accurately aligned to different UHF stations corresponding to said detent positions and a nonambiguous digital dial arrangement may be employed to indicate to the operator exactly which UHF station is being received. Electronic fine tuning is provided to permit the UHF tuner to be fine tuned independently of the position of the selector shaft.
