ABSTRACT:
A multi-band receiver for receiving broadcast signals divided by frequencies into an FM group and a TV group, the TV group including at least two different frequency ranges separated by a substantial frequency gap. The receiver includes a band selector for selecting a desired frequency group from the two group, a tuning controller for selecting a desired broadcast frequency within the desired group from a predetermined tuning band, an oscillator for separating signals of the desired frequency from the received broadcast signals and converting the separated signals into audio signals and a frequency adjuster responsive to the band selector and the tuning controller for automatically adjusting the oscillation frequency of the oscillator when the TV group has been selected for substantially removing the frequency gap from the predetermined tuning band.
