ABSTRACT:
A station-signal frequency indicating system for a radio receiver, in which the content in a counter counting an output of a local oscillator in the receiver is temporarily retained by a latching circuit and in turn is displayed by an indicator, and in which a control circuit inhibits the retained content in the latching circuit from being changed, immediately after the receiver is tuned exactly to a station signal until the receiver is detuned from this station signal.
