The paper presents the functional circuit synthesizer modified FM signals and pi ± pi / 2 phase knockouts, develop appropriate structures of receivers for such signals, identify potential channel selectivity. Developed antenna-feeder devices for the case of the air link with the used of this type of signal, the criteria of the reliability of the system and the rules of verification work. The developed system can be used in all cases where the information transmitted by one reason or another should not be subject to the information lossy compression.
