RADIO STATION

FIELD: radio communication for shipboard and ground radio centers. SUBSTANCE: radio station designed for operation in very long-, medium-, and short-frequency bands has receiving unit incorporating first and second receivers and signal processing and control unit, as well as transmitting unit with transmitter and set of final devices; data outputs of receivers are connected to respective first and second inputs of signal processing and control unit whose third data input and data output are connected, respectively, to data output and input of set of final devices; in addition, first and second receivers as well as set of final devices are connected through separate control lines to signal processing and control unit. Newly introduced in radio station are series-connected radio traffic monitoring unit, timer, and serviceability check unit, as well as OR gate and receiver/exciter whose data input, first, second, and third outputs are connected, respectively, to data output and input of final devices, data input of transmitter, and in parallel with data check inputs of first and second receivers; receiver/exciter is also connected through separate control lines to set of final devices and to transmitter; additional output of set of final devices informing about absence of communication request signal is connected in parallel with first inputs of radio traffic monitoring unit and OR gate whose second inputs are connected in parallel with additional output warning about radio traffic failure and that of signal processing and control unit which is also connected via control line to data check-up unit; output of OR gate is connected to CLEAR input of timer; set of final devices has external output for connecting additional set of final devices. EFFECT: improved reliability and traffic-carrying capacity of radio channel, facilitated operation and maintenance, simplified design of radio station. 2 dwg
