PURPOSE:To prevent the head omission of a transitting signal by providing a means to delay a demodulated signal so that the demodulated signal is supplied to a transmitter after the point of time of the start of the transmitter is completely over. CONSTITUTION:A radio wave is received by a receiving antenna 1 or 6, and its high frequency signal is inputted to a receiver 2 or 4, and is demodulated. When the level of the demodulated signal S1 or (S1) exceeds a squelch level, a squelch signal S2 or (S2) is outputted to the transmitter 5 or 3, and simultaneously, the demodulated signal S1 or (S1) is inputted to a delay circuit 7 or 8. The circuit 7 or 8 delays the demodulated signal so that the demodulated signal S1 or (S1) is supplied to the transmitter after the point of time of the start of the transmitter 5 or 3 is completely over. Thus, by outputting the demodulated signal based on a repeated and demodulated sound signal or data to the transmitter after waiting the complete start of the transmitter, the head omission of the repeating transmitting signal is prevented. |
