ABSTRACT:
An electronic tuner, particularly suited for a VHF/UHF television receiver using voltage tuned circuits. A two digit decimal channel selector has a binary coded output. The output representing the channel selected is connected with both a VHF decoder and a UHF decoder which includes a memory programmed for a plurality of UHF channels. A memory scanner and a comparator choose the selected UHF channel from the memory and actuate the tuning means for the selected UHF channel. A UHF programmer directs storage of channel indicia at a selected address in the memory.
