Professional Digital Mobile Radio

Professional Digital Mobile Radio

With superb performance, high reliability, and strong expandability, the DMR mobile radio family enriches your communications.


Product Features

·User-centered Design

The large-size color display allows good visibility even under extremely strong light. And the seven programmable keys facilitate your communication in various conditions.

·Reliable Quality

MD78X/78XG is strictly compliant with MIL-STD-810 C/D/E/F/G and IP54 standards, ensuring outstanding performance even under harsh environments.

·Superior Voice

With the combined application of narrowband codec and digital errorcorrection technologies, MD78X/78XG is capable of ensuring you superior voice under noisy environments or at the edge of the coverage area. In addition, the adoption of the AGC technology also optimizes your voice. With a built-in 4W speaker, MD78X/78XG ensures clear and crisp voice communication.

·Higher Spectrum Efficiency, Higher Channel Capacity

Benefiting from the TDMA technology, MD78X/78XG allows twice the channels based on the same spectrum resource. This is a big help to relieve the stress of increasing shortage in spectrum resource.

·Dual-slot Pseudo Trunk

With this feature, the free slot can be allocated to a member that needs to communicate, effectively enhancing frequency efficiency and allowing you to communicate timely under emergency situations.

·Secure Communication

Besides the intrinsic encryption of the digital technology, MD78X/78XG provides enhanced encryption capability (such as 256-bit encryption algorithm) and the Scrambler feature (selectable).

·Versatile Services

In addition to conventional communication services, MD78X/78XG features rich data services and selectable functions such as Text Message, Scan, Emergency, Channel Steering, Auto Registration and Lone Worker.

·Further Development Port

The reserved front and rear port in MD78X/78XG allows users or any third party partner to further develop other helpful applications to extend the radio functionalities!

·Option Board Interface

MD78X/78XG supports option board interfaces to radio, allowing third party partner to develop various applications to interconnect with radios to control the radio to expand its functionalities! Among the supported features are voice recording, encryption etc. Please refer to the API Partner Programmed for more information!

 Main Functions

·Dual Modes (Analog+Digital) 

MD78X/78XG can operate in either analog or digital mode. It is compatible with the prevalent analog system, ensuring a smooth analog-to-digital transition.

·Versatile Voice Calls

Intelligent signaling of MD78X/78XG supports various voice call types, including Private Call, Group Call , All Call and Emergency Call.


MD78XG supports viewing of GPS positioning information and sending of GPS text message.

·Data Services

MD78X/78XG supports data capabilities of sending Private, Group text message. It also supports Third Party to control the radio via Third party API (GPS, Radio Registration Services, Radio and Call Control, Telemetry, Data Transfer), via Telemetry control to radio.

·Accessory Expansion

MD78X/78XG supports third party to develop accessories expansion via front and rear port of the mobile. (Check out that features as channel steering, emergency footswitch has been supported via the back port!)

·Various Analog Signaling Types

MD78X/78XG supports various analog signaling types (HDC1200, DTMF, 2-Tone and 5-Tone), various squelch control types (CTCSS/CDCSS), thus providing higher function expansion capacity to the analog world.

·Supplementary Services

MD78X/78XG supports supplementary services of Radio Check, Remote Monitor, Call Alert, Radio Enable and Radio Disable.

·Multiple Languages

MD78X*/78X*G supports 13 languages, including English, Simplified Chinese, Traditional Chinese, German, Spanish, French, Italian, Polish, Russian, Turkish, Greece, Portuguese and Korean, allowing users to select it per their needs.

·One Touch

MD78X/78XG supports One Touch features that comprise of Text Message, Voice Calls and Supplementary Services.


MD78X/78XG supports scanning of pure Analog voice and signaling, pure Digital voice and data, and also mix mode scan that comprise of Analog and Digital activities. 


MD78X*/78X*G supports automatic roaming of all sites in a IP Multi-Site Connect systems.

·Privacy of Voice and Data

MD78X/78XG supports Analog scrambling, and digital encryption using Advanced Encryption Standard (AES) and ARCFOUR (ARC4) encryption methodology to both voice and data.

·Analog/Digital Telephone Interconnect (via DTMF signaling)

MD78X/78XG supports simplex voice communications between radio and telephone users. It allows a radio user to make a telephone call; or a telephone user to make either a Group or Private call to radio users. This feature utilizes the Commercial Off The Shelf (COTS) Analog Phone Patch boxes and a Plain Old Telephone Service (POTS) line to connect the radio users to the Corporate Office Phone System (PBX) or Public Switched Telephone Network (PSTN).

·Software Upgradable

 With this capability, you can enjoy firmware upgrade without purchasing a new piece of radio hardware!
