The New Standard of Quality and Performance.

For In-Vehicle Communications, Desktop Dispatching, and Expanding Coverage Areas with Voice and Data Connectivity

The HM782 Mobile Radio is the next-generation in creative style and functionality that elevates the industry standard in professional digital two-way radios. The HM782 is the new state-of-the-art in mobile radios, providing a more efficient and reliable experience with loud and clear audio, an intuitive user interface, and gateway connectivity between radio and data networks.

Our state-of-the-art communication solutions can provide everything your business needs to grow. Learn more on how Cardinal Communications can develop a customized solution for your business needs! Contact Us!


Multi-System Flexibility

The HM782 can be deployed in Analog and Digital Conventional, MPT and XPT Trunking, DMR Tier II and Tier III Trunking, IP Multi-Site Connect, and DMR Simulcast Systems.

Greater Calling Flexibility

The HM782 supports Individual Calls (radio to radio, radio to dispatcher), Group Calls (one radio to many, dispatcher to many), All Call (broadcast call to all radios, transmit only), and Telephone Calls (with connectivity to PSTN, PABX or SIP networks).

Clear and Bright Display

The HM782 features a 2.4-inch, 240x300 HD TFTLCD display with an intuitive six-grid navigation interface with large type and icons. The display supports 262,000 colors, and is clearly visible in bright sunlight.

Enhanced Worker Safety

The HM782 radios are designed for worker safety with an easy access emergency button, emergency calling, and priority interrupt. Lone Worker prompts the user to press a key at preset intervals to indicate they are safe. Large tactile knobs and piano-style buttons provide easy access that keep eyes on the road.

Louder and Clearer Audio

Hytera provides industry-leading audio quality through an optimized forward-facing loudspeaker and AI-based voice enhancement with deep learning ability that can accurately extract voice from noise in real time and decreases unwanted background noises as loud as 30db.

Enhanced GPS Location Tracking

The HM782 reports current location information to other radios, the dispatcher, or a third-party applications in real time, enhancing the efficiency of visualized dispatch applications. GPS data is transmitted during voice calls for immediate location targeting, and GPS data can be compressed to increase channel capacity and reduce hardware cost.

Higher Security

The HM782 supports Digital End-to-End and Overthe- Air Encryption for voice and data. Hardware encryption is implemented through a built-in encryption card. Advanced software encryption uses the ARC4 and AES encryption algorithms.

Durable and Rugged

IP54 compliant for water and dust ingress, and MIL-STD- 810 G for shock and humidity.

Single Frequency Repeater

SFR mode on the HM782 enables repeater operation on a radio channel that transmits on one slot and receives on another slot using the same frequency. SFR mode extends coverage in field operations with long distances and variable terrain.


The HM782 can be deployed Back-to-Back to enable communication between analog and digital radios, or radios with different frequencies. Two HM782 radios can be deployed Back-to-Back, or one radio and a repeater can be used.

Wireless Link

In situations where a wired IP network is unavailable between two repeaters, two HM782 radios using different frequencies can provide a wireless link between the repeaters.

IP Mulit-Site Connect

Multiple HM782 mobile radios can be connected to an Ethernet/IP network to provide a reliable and cost-effective method to connect remote radio sites and extend coverage areas. IP Transit can connect radio sites with analog or digital radios, and radios with different frequencies.

Clarity Transmission

The Clarity Transmission feature provides a wireless data path between remote network devices and a central network management station. HM782 radios function as compact gateway devices and provide wireless channels that transparently transmit data without any modi
