FIELD: radio communications. SUBSTANCE: multiband radio station is, essentially, multiple-access station using code division of channels that operates at many frequencies for transmission or reception. Transmission path functions using division of intermediate-frequency transmission channel and mixing of intermediate frequency with two different transmission frequencies by means of frequency synthesizer. Receiving path has two high-frequency receiving channels whose high frequency is mixed up with synthesizer- generated frequencies and summed up in one intermediate-frequency amplifier. Proposed radio station enables easy relinquish of watch between frequencies that is establishing communications with next base station before ceasing communications with first station at the same time communicating with more than two stations simultaneously. EFFECT: enlarged functional capabilities. 12 cl, 3 dwg
