Motorola MTM5400

Introduction

   The Motorola MTM5400 is a cutting-edge TETRA mobile radio supporting TETRA Enhanced Data Service (TEDS) capability, offering faster data connectivity. Known for its superior RF sensitivity and 10 W transmit power, the MTM5400 excels in TETRA RF performance.

  It supports multiple operational modes for reliable communication in weak coverage areas and features a Type 1A compliant DMO Repeater for efficient spectrum usage. The integrated gateway connects Direct Mode users with control rooms and trunked network colleagues, supporting various call types.

  Advanced Remote Terminal Management allows live programming and software upgrades, reducing downtime. Flexible installation options, including full DIN-A compatibility, make the MTM5400 ideal for diverse applications, from desk setups to motorcycle installations.

The Motorola MTM5400 is highly desired model in the ham radio community. Its hardware is particularly favored for setting up multimode gateways like DMR2TETRA, TETRA2PoC, SVXLink gateways, or for use in DMO repeater mode.

 Note that Motorola MTM5400  does have a factory default “COR” pinout on the rear accessory connector!

Motorola MTM5400 Sales Model Nomenclature

 

   This nomenclature includes information about the product’s features, specifications, and intended use, and helps both the manufacturer and customers to distinguish between different versions or configurations of the product.

  Motorola TETRA radios are available with various firmware versions, each featuring one of the following standard AIE TETRA Encryption Algorithms (TEAs):

– CLEAR NonE2 (No Encryption) This is the only one for HamRadio use!
– TEA1 is for commercial use and is primarily used by critical infrastructure around the world. But it’s also used by some police and military agencies outside of Europe.
– TEA2 (restricted to use by Schengen / EU countries). Possession of TEA2 radios is in many countries
prohibited by law!
– TEA3 Essentially the export version of TEA2 which is for use outside of Europe by the same kinds of entities that use radios with TEA2.
– TEA4 For commercial use but is hardly used.

In 2022 ETSI introduced additional algorithms, TEA 5, TEA 6 and TEA7, in order to future-proof the technology against quantum attacks. The entire set of these original and additional algorithms will be made available in the public domain as well as TAA1 (the original authentication and key management specification) and TAA2 (the new authentication and key management specification).

Each TEA version builds upon the previous one, incorporating enhancements to meet evolving user needs and address emerging challenges in communication security and efficiency.

Adaptation for Ham Radio Use

 The Motorola MTTM5400 it is most desired and used in HamTetra and adapted for gateway builds like SVXLink or to be used  in DMO Repeater Mode

Attention! Due to the nature of the radio market, some units may originate from governmental working environments, still in use, stolen, lost, or intended for destruction but salvaged by individuals. If you notice any signs such as radio logos, initial messages, back labels, or additional markings indicating that the radio might be a “tea 2” or not a “clean radio,” do not purchase it. Instead, return the radio to the seller or report it to the nearest police station.
Only Clear radio firmware can be used for HamTetra use!!

Programming

To program the Motorola MTM5400 you will need a compatible programming cable and Motorola Tetra CPS or Motorola Tetra CPS Depot software. Additionally, for firmware upgrades, depend of existing radio firmware you need the right RPK file. Motorola MTM5400 firmware can be upgraded through Motorola Tetra CPS or Motorola Tetra CPS Depot software.

Warning!

The following software versions are limited to the specific radio types:
• MR10.6.3 is limited to MTM5200, MTM5400, MTM800FuG
• MR10.6.5 is limited to MTM5500, MTM800FuG ET
Do not mix the radios above with their dedicated software versions.
Such action will require radiosto be returned to Motorola Repair Centre   for recovery.

——————————-

Do not connect MTM5200, MTM5400 and MTM800FuG Control Heads to the Enhanced (Ethernet)
MTM5500, MTM800 Fug ET radio (and the other way around). Even though mechanically possible,
it is incorrect and will effect in hardware malfunction (broken transceiver).

Please refer to the Radio Quick Start Guide

Programming Cable

Programming the Motorola MTM5200 is a straightforward process thanks to the availability of dedicated programming cable.This cable facilitate seamless communication between the radio and programming software, allowing users to customize settings, configure channels, and update firmware with ease.

Programming Cable for use:

Motorola PMKN4105A Serial Programming Cable (RIBless)
Motorola HKN6184 USB Control Head Programming Cable (GCAI)
Motorola PMKN4110A MTM5200 MTM5400 MTM5500 Rear Programming Cable

Detailed information to build your own compatible MotorolaMTM5400 USB/SERIAL Data Cable was also published on the website.

Antenna Considerations

For the Motorola MTM5400 radio, two types of antennas are applicable: mobile and base station antennas. When selecting an antenna, it’s important to match it to the radio’s operating frequency
