PURPOSE: To receive two selective calling codes or over through a single channel by identifying either code among two selective calling codes or over through the single channel and providing an output of a voice signal from a voice signal path only when the identified code is coincident with a set code. CONSTITUTION: An output signal of a mixer 3 in a reception section of the radio equipment is given to an intermediate frequency circuit 4, in which the signal is converted into an intermediate frequency signal, a demodulator 8 demodulates a voice signal and a selective calling code and an LPF 9 and an HPF 10 divide the demodulated signal into the voice signal and the selective calling code. The selective calling code from the LPF 9 is given to a plural selective calling code identification circuit 16 identifying two selective calling codes or over through a single channel, in which the codes are coincident with any code set as channel data 15 resulting from setting two selective calling codes or over through the single channel in advance. As the result of identification, a mute circuit 12 is operated only when they are coincident and the voice signal passing through the HPF 10 is outputted from a speaker 14 via a voice frequency amplifier 13 and received through the single channel. |
