PURPOSE:To recognize which broadcast station is memorized quite obviously by connecting each memory circuit of broadcast stations to an output side of a frequency display data circuit and displaying the name of broadcast station by its output code. CONSTITUTION:A frequency display device 5 displaying the frequency during receiving and a broadcast station name display device 8 comprising a broadcast station name memory circuit 6 and a broadcast station name display device 7 are connected to theoutput side of a frequency display data circuit 4 assembled in an AM/FM radio receiving circuit 1 of the PLL synthesizer system. The circuit 6 takes a frequency of the broadcast station as an address and outputs the code of the broadcast station name to the display device 7. The display device 7 displays the broadcast station name by displaying the code in terms of characters. Thus, the possibility of forgotten storage of the broadcast station name is precluded. |
