ABSTRACT A channel programming and indicating system for a television receiver, in which a programming of channel numbers is achieved by a plurality of receiving channel selecting switches. A random access memory is used to program channel numbers by the channel selecting switches in accordance with a selected position. In addition to the foregoing there is a device responsive to one of the switches for coupling a tuning voltage derived from an associated channel selector to the electronic tuner. A memory and an address signal generating device couples between the channel selectors and the address terminals. A data signal generator between the switches and the memory means together with a channel indicator coupled with the output of the memory and mode switches are further provided whereby the switches have in one mode the function of channel selection and in another mode the function of providing a programming path for the output of the memory, thereby yielding a given channel number for a given address of the memory. The channel selector comprises a pulse generator, a counter, a decoder, and a tuning voltage generator.
