Expanded dial arrangement for 56 channel UHF tuner

摘要

The channel selector shaft of a 70 channel mechanically detented UHF tuner is provided with mechanical stops which prevent the shaft from moving above UHF channel No. 69 so that the upper twenty-four UHF channels are unused. Also, a dial driving arrangement is provided for driving an expanded UHF dial having only 56 channel indicia so that the 56 channel indicia cover substantially the same area on the dial as the 70 channel indicia of prior art arrangements.
