PURPOSE:To perform the message communication with high efficiency by securing such a constitution where the radio equipment of a called radio station stores signals to a memory and also sends back automatically a confirming signal consisting of a code of own station, a code of the station at the remote side and a state code. CONSTITUTION:The input selected by a changeover switch 23, i.e., the output obtained by amplifying the microphone output or the output of an MODEM24 is supplied to an FM modulator 25 and supplied to a transmission part 26 after FM modulation. The output of the part 26 is supplied to an antenna 28 via a changeover switch circuit 27 and transmitted. The radio wave received by the antenna 28 of another radio station is supplied to a reception part 29. The reception output is supplied to an FM demodulator 30 and demodulated. While a CPU35 supplies data to an encoder 47, the switch signal to the circuit 23, the mute indicating signal to a voice amplifier 31, the display data to display devices 48, 50, 51 and 52 respectively and the drive signal to a buzzer 48 via an output port 39 respectively. |
