Abstract

PURPOSE: To enable to obtain the reception information even outside of car, by radiating the reception output signal as weak electromagnetic waves through the use of transmission circuit.
CONSTITUTION: When the operator departs the car with the switch 15 turned on, the oscillation and modulation section 2 of the transceiver 11 is operated with the low frequency amplifying section 1 and oscillation is made with the different frequency from the transmission. Modulation is made with the reception output signal via the conversion circuit 12 and the modulated output is radiated via the multiplying output control circuit 13 and the antenna for weak electromagnetic waves. Accordingly, the operator receives weak electromagnetic waves with the portable receiver, being allowed to confirm the information from the opposing station
