Hytera MD785G Duplex

DMR mobile radio that supports the digital trunked radio according to ETSI standard.

    Product description

    The MD785G duplex from Hytera offers ergonomic design in combination with functions according to DMR Tier III, the DMR radio standard for digital trunked radio. With the MD785G duplex, duplex calls can be made without having to press the PTT button. A handset with a complete keypad are required for communication.



    Intuitive interface and key guidance

    The high-resolution LCD screen offers a clear display, even under difficult light conditions. The large keyboard and ergonomic programmable keys enable efficient and productive communication.

    Reliability and quality

    The MD785G Duplex meets the US military standard MIL-STD-810 C/D/E/F/G and offers protection against dust and moisture in accordance with IP54. This enables this mobile radio to provide reliable service even un harsh environments.

    Excellent voice quality

    By use of narrow band codecs and digital error correction, the MD785G duplex offers you an outstanding audio quality even in loud environments and in boundary regions of the radio coverage. Moreover, the technology employed optimizes the transmitted language. The built-in 4-watt loudspeaker completes the clear transmission of the radio communication.

    Improved utilization of the frequency spectrum

    Thanks to the TDMA process, the MD785G duplex enables you to assign the available bandwidth with double number of channels. This has a clear mitigating effect on increasing spectrum scarcity.

    Versatile functionality

    Besides the classic communication functions, the MD785G Duplex features numerous digital and optional functions, including text messages, GPS location determination and a one-person function.

    Interface for hardware expansion

    The hardware of the MD785G duplex can be expanded using the Option Board interface. Therefore, third-party suppliers are able to develop additional functions.

    Duplex communication

    The TDMA procedure enables simultaneous two-way voice communication, while requiring no PTT button just like a telephone call. With the implemented digital technology, DMR trunked radio systems from Hytera achieve the same quality as conventional PSTN telephone calls.

    Versatile voice communication

    Thanks to digital signal transmission, the MD785G Duplex provides you with different call types: Individual call, group call, emergency call, include call, broadcast call, PSTN/PABX call, semi-duplex call and full-duplex call.


    The MD785G duplex supports GPS location determination and sending GPS location data as text message.

    Data services

    The MD785G offers you data services, such as sending text and group messages. Moreover, the MD785G duplex can be used in radio solutions with additional application software, such as AVL or Radio Call Control.

    Different menu languages

    MD785G duplex supports various menu languages, including German, English, Spanish, French, Italian, Polish and Portuguese. Other languages can be added on request
