PURPOSE:To eliminate the need to operate a transmitter and a receiver simultaneously by storing received communication information in a storage part temporaily and by sending the stored information from the transmitter on reception. CONSTITUTION:If a transmitter-receiver 31 receives a radio wave having continuation time equivalent to a frequency f1 at which it is expected to operate as a repeating device at, the received signal is led to a storage part 32, wherein it is stored while the transmitter-receiver receives the radio wave of the f1. The start and stop of reception can be known by a reception part squelch signal, so a control part 33 starts and stops the operation of the storage part 32 with the squelch signal. Simultaneously with the stop of the operation of the storage part, the received signal stored in the storage part 32 is added to a transmitter-receiver demodulation input 32 by being read from its beginning. Simultaneously, the control part 33 controls the transmission control terminal of the transmitter-receiver to place in the transmitter-receiver 31 in a transmission state. |
