RECEIVING-TRANSMITTING STATION OF TELEPHONE COMMUNICATION OF DIVERS WITH TRACKING VESSEL Russian patent published in 2020 - IPC B63C11/00 H04B13/02 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to underwater communication equipment, in particular to means of communication of divers, and can be used for communication of divers when working with accompanying vessel or shore station. Receiving and transmitting station for hydroacoustic telephony of divers comprises a microphone amplifier, a voice dialing unit, an encoder, a modulator, a power amplifier, a series-connected preamplifier, a demodulator, a decoder, a speech synthesizer, a flexible hose and a reversible hydroacoustic transducer. Station additionally comprises two ultra-shortwave radio stations, the first of which operates only in reception mode at frequency ƒ₁, and second is only in transmission mode on frequency ƒ₂, interfacing units, sealed detachable connector, second flexible hose and second reversible hydroacoustic transducer. All elements of receiving-transmitting station, with the exception of flexible cables with reversible hydroacoustic transducers, are placed in buoy, having sealed housing of radiotransparent material.

EFFECT: longer range of communication of divers with tracking boat.
