MOTOTRBO is a Motorola digital radio product marketed primarily to business/industrial users, but has found its way into some public safety uses. The format is based on, and compatible with the European 2-slot DMR standard and uses Time Division Multiple Access (TDMA) to effectively accommodate two simultaneous users. A single 12.5 kHz channel is able to carry two simultaneous and independent conversations, or simultaneous and independent voice and data paths each with 6.25 kHz equivalency, however the bandwidth of DMR exceedes the maximum required for UHF 6.25 kHz channel centers. Operation of different talkgroups and talkpaths similar to trunking is possible, as is wide-area operation through IP connectivity. MOTOTRBO transceivers and repeater stations may be retrocompatible with analog FM using CTCSS or CDCSS.

No scanner can monitor this digital format by itself but it can be monitored with DSD.

Emission designators for MOTOTRBO: 7K60FXE (voice), 7K60FXD (data).

MOTOTRBO is based on the following ETSI standards.

The standard includes provisions for trunking - a feature not yet offered by Motorola's MOTOTRBO.

  • ETSI TS 102 361-4 Trunking

Additional information on DMR is available through the Digital Mobile Radio Association.
