Abstract

PURPOSE: To miniaturize and stabilize a unit by storing an electronic memory circuit with a tuning voltage equivalent to a station to be received selectively and then by providng only one variable voltage divider which divides a reference voltage to store each tuning voltage.
CONSTITUTION: Variable voltage divider 11 dividing a reference voltage from reference voltage source 9 is adjusted so as to receive desired channel (a). Main control circuit 16 stores the voltage-divided voltage of previously adjusted voltage divider 11 in the digital format at a memory address of memory circuit 12 corresponding to channel (a). Next, mode changeover switch 13 is switched to the other side and contact 7a is made in contact with a human body, etc., to transfer a signal to circuit 16. Circuit 16 operates circuit 12 and D/A converter circuit 15 to read the memory content of circuit 12 at the address corresponding to channel (a), and it is transmitted to circuit 15. The output of circuit 15 is applied to varactor diode 4 to receive desired channel (a). Channels (b)∼(n) are similarly channel-selected.
