In a single-voice-signal-per-carrier communications system, means are provided for limiting the intermodulation distortion in a common amplifier of a plurality of talkspurt voice signals. Separate carrier waves and voice signals are applied to respective modulators. The voice-operated-switch signals associated with respective voice signals are applied through a limiter circuit to the respective modulators. The limiter circuit limits the number of modulators generating talkspurt signals at any instant to a number which avoids intermodulation distortion.
