PURPOSE:To attain multistage relaying with carriers of the same frequency, by providing a recording and reproducing means for a relay station and transmitting signals by giving a time difference between a relay stations of each stage, in the relaying of multistage. CONSTITUTION:In a transmission station 1, a transmission signal (signal from a microphone 11) is superimposed on a selection signal P1 and transmitted 4a from a transmitter 14. In a relay station 2a, a recorder 24 is made to the recording state through the reception of a selection signal P1 for the recording of the reception signals. When the transmission of a transmission station 1 is finished and the selection signal P1 is lost, the recorder 24 stops recording, rewinds tapes automatically and reproduces the content of recording from the position of start of recording. While the recorder is under reproduction, a transmitter 26 of the relay station 2a is started and transmits 4b the content of reproduction of the recorder 24. |
