A cam follower interconnects one of the cams and the tuning shaft, and serves to rotate the tuning shaft in response to the rotation of one of the cams by the fine tuning shaft. An indicator dial provides a numerical dis- play of the precise UHF channel selected at each position of the detented selector shaft.
