RE-BROADCAST SYSTEM FOR OUTDOOR LOUDSPEAKING RECEIVER

PURPOSE:To improve the transmission reliability and maintenance by recording a broadcast from a master station once, calling a receiver in a radio wave after the end of broadcast, reproducing the broadcast sound and delivering the information in a time difference system. CONSTITUTION:This system receives a radio wave from a master station and the signal is broadcast from a speaker 5 via a signal processing section 3. In this case, the receiver is provided with a changeover device 7, a transmission section 8, a signal transmission section 19, a recording transmission control section 10, and a recording and reproducing section 11. Then the broadcast from the master station is controlled by the recording/transmission control section 10 so that the signal is recorded by the recording and reproduction section 11 from the speaker 5 and when the broadcast from the master station is finished, the signal transmission section 9 is started under the control of the recording transmission control section 10 and a call signal required to bring an opposite outdoor loudspeaking receiver into the reception state is sent and the reproduction sound from the recording reproduction section 11 is sent similarly to the case of the transmission of the call signal and the broadcast of the master station is delivered from the speaker of the opposite station in a time difference system.
