FIELD: radio engineering.
SUBSTANCE: method includes switching stereo-coder to mono mode and increasing level of output signal of coder, while depth of modulation of frequency modulated signal of carrying frequency increases, due to detecting of signals of increased level, mono-phonic receivers reproduce voice message about emergency situations.
EFFECT: higher quality of radio transmission, broader range of certain receiving of radio transceiver.
