Hytera RD985S Repeater


The RD985 and RD985S DMR repeaters from Hytera are at the heart of analogue and digital radio networks and were developed in line with the open ETSI standard for DMR. Both repeaters are characterized by their reliability and outstanding functionality.

RD985S is an advanced version of RD985 DMR repeater. The RD985s adopts a more flexible platform, offering 3 operational modes by software upgrade.


The heart of professional radio systems – All the repeaters from Hytera can be connected in digital mode via IP connection to a comprehensive radio network. In analogue mode, the repeaters can be connected together back-to-back. Both in conventional analogue and DMR modes (DMR Tier II), the RD985 and RD985S repeaters can be used with the RD625 and RD965 repeaters in a radio system.

Upgradeable for greater challenges (RD985S) – The RD985S repeater supports not only conventional analogue and digital modes but also other modes that can be unlocked with a chargeable licence. It can be upgraded
into a base station for DMR simulcast, DMR trunked radio (Tier III) or Hytera XPT radio systems. This means that RD985S is a secure investment for growing radio projects.

Improved utilization of the frequency spectrum – Thanks to the TDMA technology, twice as many users can use the same channel. Due to restricted frequency resources, this represents an important relief and reduces expense for system terminals and licences.

Dual-mode and automatic change – Both repeaters can switch independently between the digital and analogue modes, depending on the type of the receiver signal.

Secure communication – To protect your radio communications, the RD985 and RD985S repeaters over advanced digital encryption functions, according to the DMRA specification. Depending on the variant, both repeaters support encryption with 40, 128 or 256 bit.

Hytera XPT – With the RD985s, take advantage of Hytera’s Extended Pseudo Trunk (XPT) technology to significantly increase the capacity of your communication system.
