ABSTRACT:
A radio receiver includes a phase-locked loop which is locked with the tuned frequency of a broadcast radio wave applied thereto, so that the output of the phase-locked loop is displayed by a display unit to display the tuned frequency. The displayed frequency is free from possible deviation of a local oscillation frequency from the tuned frequency.
