Abstract
For the narrowband analog signals transmission via the radio channels in areas with difficult terrain the short-wave range is widely used. The majority of radio stations use frequency modulation of the transmitter, without any message encryption. This gives the opportunity to detect and intercept messages that is transmitted. The article proposes the use of a digital voice transmission method using a broadband radio signal. The calculated signal/noise ratio, which is created by a broadband transmitter on the input of the radio signals monitoring receiver, in fifty times less than for existing narrowband means of the short-wave range.
