FIELD: radio engineering, in particular, railroad communication equipment. SUBSTANCE: device has double-frequency active retransmitter, two channels, which operate at different frequencies and include stationary station and mobile station, each of which has receiver-transmitter and power supply, carrier frequency filter of another channel, amplifier for generation of ON pulse, and gate. This results in possibility of automatic turn-off of power supply of mobile stations of one channel, when mobile stations of another channel are engaged in communication. EFFECT: halved power consumption of mobile stations. 1 dwg
