And 20, pulse shapers 21 and 22, synchronizer 23, programmer 24, first, second, and third input signal buses 25 - 27, fifth trigger 28, first OR element 29, third AND element 30, second OR element 31.

The radio station operates as follows.

After the radio station is turned on, the operator is convinced that at the output of Trigger 16, logic 0 synchronizes the program by transmitting the control action on the third bus 27, sets the Standby mode 45 to receive, for which it supplies the control action on the second bus 26 and puts the fifth trigger 28 into the Logical state 1. The logical signal 1 from the output of the fifth trigger 28 comes to the PRD 5, turns off the high voltage and prohibits radiation, through the first element OR 29 enters the input of the switch 11 and switches the control of the synthesizer 6 frequencies of PFP $$ I to the PFM frequency control control unit 1. At the same time, this signal is fed to the PFM frequency memory unit 10 and allows the receiver 1 to be switched according to the fixed frequency change program generated by the programmer 24. At the same time, the block 14 provides the frequency adjustment of the synthesizer 6 in the passband + JF of receiver 1 relative to the nominal frequency fixed by the unit 10. Thus, the standby reception mode is implemented, the radio station is prepared to switch to the initial communication establishment mode.

Switching frequencies PFP 1 in the standby mode is made at certain intervals of time equal to the time intervals of switching the radio during the initial communication.

If it is necessary to establish communication, the operator of one of the correspondents submits a control action through the second OR element 31 via the first bus 25 to the pulse shaper 21. The generated pulse transfers the second trigger 16 to the logical 1 state, and the fifth trigger 28 to the logical 0 state. The logical 1 signal from the output of the second trigger 16 goes to the input of the third switch 12, through the first element OR 29 to the input of the second switch 11 and switches the control synthesizers 6 and 9 frequencies PFP 1 and PFD 5 on blocks and 15 control frequency adjustment PFM 1 and PFD 5, respectively. At the same time, this signal is fed to blocks 10 and 13 of the frequency memory PFP 1 and PST and allows the receiver 1 and transmitter 5 to be switched according to the fixed frequency change programs PFP 1 and PST 5 formed by the programmer 24. The synchronization of the formation of switching programs of the receivers 1 and the transmitters 5 of correspondents is provided by the synchronizer 23 according to the signals coming from its outputs to blocks 14, and the programmer 24, while blocks 14 and 15 provide tuning of the frequencies of synthesizers 6 and 9 in the passband + 4F of receiver 1 and transmitter 5 with respect to Inalov fixed Rx and Tx frequencies 1 5, issued by blocks 10 and 13. Switching chastot'PRM TX 1 and 5 is performed at predetermined intervals, sufficient for radio tuning, frequency and selecting the optimal exchange commands about room optimum frequency of operation algorithm

158941 of block 14 and block 15. At each time interval specified using synchronizer 23, after switching frequencies PRI 1 and Tx 5 and selecting the optimal operating frequencies according to the signal from synchronizer 23, the pulse shaper-22 starts, from the output of which the generated pulse is supplied to the third and the fourth triggers ed 18 and 19 and sets them to logical O. The logical O signal from the third and fourth triggers goes to the first element. And 17. At the same time, a pulse through the third element I 20, to the second input of which logic 1 comes from the second trigger 16, is supplied to PKU 8, BVORCH 7 to request the optimal frequency and to the first trigger 3, 20 which switches the switch 4 to state of information transmission from PKU 8 to transmitter 5.

On the front of this pulse, BVORCH 7 issues the frequency number to the second switch 11 and FCU 8, and upon the fall of this pulse, FCU 8 encodes the frequency number and provides a codogram to the input of transmitter 5 through switch 4. After the control command is transmitted according to the algorithm 39 the operation of block 15 BUCH PRD in PKU 8, a signal is generated that arrives at the first trigger 3 and sets it to its initial state, and the fourth trigger 19 - in the state of logical 1.

The second correspondent has a standby reception mode, and receiver 1 switches over at program frequencies. If the next frequency is suitable for communication, then decoder 2 will highlight the control command transmitted by the first correspondent. It will go ⁶ to the input of the third element And 30, the second input of which receives a logical 1 from the fifth trigger 28. When these commands coincide with the third element And 30, the signal through the second element OR 31 is fed to the pulse shaper 21. The generated pulse arrives at the second and fifth triggers 16 and 28, puts the first into logical 1 and the second into logical 0. Thus, an automatic call occurs, the second correspondent, the radio stations are in initial communication mode.
