Kenwood NXR1700 NXR1800 Repeater

Kenwood NXR1700 NXR1800 Repeater

MULTI-MODE, SINGLE-MINDED, SPACE-SAVING SOLUTION

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.

The CAI (Common Air Interface) 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 analogue.

A large OLED display featured on the front panel is capable of displaying the following information: MAC/IP Address, RSSI/TX Power Setting Icon, Channel Number/Name, and RF Frequency as well as Firmware/ESN/License/Error information and other statuses.

The NXR-1000 Series repeaters require only a quarter of the rack space compared to the NXR-710/810 or TKR-D710/D810 Series models.

In addition, the NXR-1000 Series repeaters take up only half the rack space of other 1U repeaters that are 19-inch wide.
