Description: In the given article the universal technological scheme of processing of speech messages with the help of technological means of systems and complexes of aviation analog radio communication in the range of VHF (namely, from 100 to 140 MHz) is proposed and justified, in the conditions of necessity to increase the level of security of the information component of speech messages. The practical component of the technical implementation of this scheme allows to carry out the modernization of existing means of on-board aviation VHF radio communication, without introducing constructive changes in existing means of onboard analogue radio communication equipment. The direct involvement of new devices such as: vocoders, crypto-encryption, frequency-phase manipulators, is proposed to be constructively executed as an independent separate unit, and ensure that it is placed in the chain with remote control panels between the microphone and the modulator in the cascades of the transmission path, and between the output of the demodulator and the entrance of the telephone in the cascades of the receiving tract. When implementing such an approach to minimize the structural changes of existing analog equipment, only the switch of work on open and closed communication channels will be added to the remote control.


Keywords: aeronautical analog radiocommunication equipment, noise immunity, noise immunity, electronic warfare, cryptoscope
