PURPOSE:To realize an application of a low voltage accumulator which is charged by a solar battery to a power source, by specially providing a high-frequency amplifying circuit to the circuit of a wireless originator and at the same time adding a means for duplex modulation by means of a duplex modulated wave generating circuit. CONSTITUTION:A duplex modulated wave generating cirucit 3 using a low-voltage accumulator that is charged by a solar battery as a power source is used along with a high-frequency generating circuit 1 and a high-frequency amplifying circuit 2. At the same time, a lighting display circuit for display of the night position can also be aded. For instance, a low-voltage accumulator B3 which is charged by a solar battery 5 and through a diode D0 drives the circuits 3 and 1 with application of an operation switch SW, and the modulated high-frequency signal is amplified by the circuit 2 to be radiated through an antenna AN. The circuit 3 is connected to an optional dividing output terminal On and scan output terminal Sn to obtain the frequency signal. |
