ABSTRACT OF THE DISCLOSURE A channel programming apparatus for a signal receiver is disclosed in which there are provided a tuner device having a variable reactance device, the frequency of the signal received by the tuner device being determined by a voltage supplied to the variable reactance device, a tuner control apparatus for generating the voltage supplied to the variable reactance device, the tuner control apparatus generating a predetermined voltage when a power switch for the signal receiver is turned on, a timing circuit for generating a time code representing the present time and including a reference signal generator and a frequency divider for dividing the frequency of the reference signal, a first input key member for generating a time code representing the time at which the power switch is turned on, first memory for memorizing the time code from the first input key member, a coincidence detector for detecting the coincidence of the outputs of the timing circuit and the first memory and generating a coin- cidence output when the outputs of the timing circuit and the first memory coincide with each other, a circuit controlled by the coincidence output and for turning on the power switch, a second input key member for generating a programed channel code, a second memory for memorizing the programed channel code from the second input key circuit, a detecting circuit for detecting the presence of the programed code in the second memory, an AND gate supplied with the coincidence output and the output of the detecting circuit, and a circuit controlled by the output of the AND gate and for supplying the programed channel code of the second memory to the tuner control apparatus. -2-
