FIELD: radio communications; communication systems of tactical units of management. SUBSTANCE: proposed equipment provides for simultaneous transmission of narrow-band analog signal and digital signal in the form of broadband phase-keyed signal whose expansion is effected within desired frequency band of narrow-band analog signal. Equipment has low-frequency amplifier, modulator, exciter, power amplifier, transmitting and receiving antennas, two frequency synthesizers, high-frequency amplifier, intermediate-frequency channel, broadband phase-keyed signal receiver, delay circuit, rejection unit, and also broadband phase-keyed signal shaper, demodulator, adder, and three switches. EFFECT: provision for hiding broadband analog and digital signal transmission; enhanced amount of data transmitted. 6 dwg
