Features

Improved utilization of the frequency spectrum

The PD685g can be operated in TDMA direct mode and pseudo trunking. This assignment of the available bandwidth with double the number of channels leads to a significant easing of the increasing shortage of frequencies in the operation of DMR mobile radio systems compared to analog mobile radio systems.

 

Expanded frequency range

The frequency range in UHF stretches from 400 MHz to 527 MHz.

 

Versatile

The PD685g possess both an analog mode and a digital mode and is compatible with analog radio systems; as a consequence it is very easy for you to change to the digital age. Along with conventional DMR (DMR Tier II, the PD685g also support DMR trunked radio. In addition, it can be used in Hytera XPT and simulcast systems.
