Radio receiver operable in station search mode or station select mode

A radio receiver comprising:

• local oscillator means for producing a local frequency signal;
• mixer means for producing an intermediate frequency signal by mixing said local frequency signal from said local oscillator means with a broadcast signal received by said receiver;
• detector means coupled to said mixer means for demodulating said intermediate frequency signal;
• computing means connected to receive said local frequency signal for computing an algebraic sum of a number corresponding to the local frequency of said local oscillator means and a fixed number corresponding to the intermediate frequency, said algebraic sum representing tuned frequency information of said receiver;
• counter means for counting clock pulses within a range between numbers corresponding to upper and lower limits of a receiving frequency band of said receiver, a count of said counter means representing broadcast frequency information to be received by said receiver;
• comparing means for comparing the count of said counter means with output information from said computing means;
• means coupled to said comparing means for controlling the oscillating frequency of said local oscillator means in response to said comparing means by shifting the oscillating frequency of said local oscillator means when said tuned frequency information from said computing means is not coincident with said broadcast frequency information from said counter means, and fixing the oscillating frequency of said local oscillator means when said tuned frequency information from said computing means is coincident with said broadcast frequency information from said counter means;
• clock pulse generating means for supplying said clock pulses to said counter means so as to shift said broadcast frequency information from said counter means;
• tuning detecting means coupled with said detector means for detecting that said receiver is tuned to the broadcast signal;
• and
• means responsive to said tuning detecting means to disable said counter means from counting said clock pulses from said clock pulse generating means when said receiver is tuned to the broadcast signal.
