An electronic circuit having reverse scan tuning comprises an IC radio
having the forward scan function, in which a VCO capacitor is connected
in parallel to a series connected resistor and switch, and a second
switch is connects an input to an IF limiter amplifier to either circuit
ground or a voltage supply. The invention makes it convenient for a user
to search for a radio station by not having to start a search for a lower
band station at the lowest end of the frequency band. The user does not
need to push reset button to return to the lowest frequency when the user
wants to receive a station whose frequency is lower than the current
station.
