Abstract
An all-channel two mode television tuning system includes a counter for generating channel numbers to adjust tuning. An 82 .times. 1 bit read/write memory is addressed in a program mode by the generated channel numbers to provide locations for storage of signals for tuning to preselected channels. Counting speed selection means control the counter to provide both fast and slow speeds in the program mode permitting convenient generation of any channel numbers. In the operate mode channel numbers are again generated, logic circuitry accesses the memory locations to determine if generated channel numbers correspond to preselected channel numbers, and channel number generation is automatically stopped when correspondence with a preselected channel number is determined.
