Abstract

PURPOSE:To make it possible to utilize a radio receiver for a rally car, etc., by providing an automatic channel-selecting circuit PLL circuit with an additional stopwatch function while using a crystal oscillator and display unit in common. CONSTITUTION:Local oscillator 12 connected to receiving circuit 11, frequency divider 13, LPF19 and phase comparator 16 constitute PLL circuit 11A and the output of crystal oscillator 17 is supplied to comparator 16 via divider 18 and also divided by stopwatch frequency divider 22 before being inputted to decoder 20 via counter 23. Additionally, a dividing-ratio signal sent out from controller 15 is decoded and displayed on display unit 21. Then, the output signal of divider 18 is divided by counter 23 and reference pulses of a stopwatch are counted to generate stopwatch data. When counting is started with push-button switch 23a, counter 23 is reset and data from counter 23 are displayed on display unit 21 through the decoding of decoder 20.
