NXR-1700 / 1800
NXR-1700 / 1800 (DMR / Analogue / NXDN) DMR Repeater
This compact, multi-mode conventional repeater – key digital communications equipment that is a KENWOOD specialty – supports the features and performance to make it a worthy successor to the existing DMR and NXDN repeaters such as the TKR-D710/D810 and NXR-710/810. The digital protocol is chosen when ordering to set up individual units for either DMR or NXDN, with the option of keeping the factory default setting of FM analog.

The Kenwood DMR range of digital Base Station / Repeaters offer the capability to accommodate more channels or user groups and operate across a longer range or wider area in a cost effective communications infrastructure for single-site/local area applications. They share benefits of digital radio communications in providing increased range, improved sound quality and advanced security capabilities.
SOLID REPEATER PERFORMANCE
Capable of outputting up to 50 W in the 136–174 MHz frequency range, and up to 40 W in the 400–MHz range, the NXR-1700 / 1800 repeater is compatible with the DMR Tier II air interface operating in both digital conventional and FM analogue conventional modes.
CONVENTIONAL IP NETWORK
To further expand coverage, you can employ IP connectivity to link multiple conventional repeaters installed in different sites. Each repeater is equipped with a KTI-5 Network Interface Unit to provide the required Ethernet capability.
MIXED-MODE
Kenwood DMR repeaters can be configured to operate in Mixed-Mode which allows the repeater to switch automatically between analogue and digital, depending on what signal has been received. If an analogue radio transmits, the repeater switches automatically to analogue mode to repeat the analogue call, if a digital radio transmits, then the repeater switches automatically to digital mode to repeat the digital call. The repeater only repeats the calls that are qualified by CTCSS/DCS (QT/DQT) in analogue or Colour Code in digital mode. While the repeater repeats one analogue call at a time, it can repeat 2 digital calls at a time, one on each logical channel.
DIGITAL & ANALOGUE OPERATION
Operates in DMR Digital and FM Analogue modes, even on the same channel. Auto-senses Received Mode (Digital or Analogue).
