Hytera HM785LG BT 136-174 MHz, low power, GPS, BT

The HM785 DMR mobile radio is the next generation of professional digital mobile radio providing greater flexibility and scalability.
This mobile radio with DMR technology supports a single control head as standard with options for remote control head mounting
and dual control head to suit different environments (such as vehicles, motorcycles and fixed control rooms) ensuring efficient
communication. The new UI interface facilitates faster operations and the AI-based noise cancellation technology guarantees clearer
voice even in the noisiest environments. It is also the first ever DMR radio that can support the IP Transit Solution feature. It comes
with a rich digital mobile feature set including a broad range and ability to integrate into existing services, which provides greater efficiency.
