Introduction
The Motorola MTM800 Enhanced is an upgraded version of the MTM800, featuring a larger color display for better readability, superior audio quality with improved noise reduction, and enhanced connectivity options including better GPS and advanced data services. It also offers increased memory and processing power, more robust security features, and supports more advanced software applications, making it a more powerful and versatile communication tool for critical operations.
The Motorola MTM800E is extensively utilized in the ham radio community as a base station or mobile unit. It is particularly favored for setting up multimode gateways such as DMR2TETRA, TETRA2PoC or with some small modifications for SVXLink gateways, thanks to its robust performance, reliable connectivity, and flexibility in various communication setups. This makes it a preferred choice among amateur radio operators for advanced communication systems.
Motorola MTM800 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 MTM800E is the most used Tetra radios adapted for Ham radio use. It can be adapted for gateway builds like SVXLink with some modifications.
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 MTM800E, 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. MotorolaMTM800E firmware can be upgraded through Motorola Tetra CPS or Motorola Tetra CPS Depot software.
The programming Active Data Cable, “GMKN1022”, is only compatible when an Expansion Head is not fitted as part of a remote mount configuration. In this configuration access to the Tetra PEI for IP Packet Data and SDS services is available on the Expansion head and the Active Data Cable GMKN1022 is not required.
Please refer to the Radio Quick Start Guide
Programming Cable
Programming the Motorola MTM800E 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 GMKN4067/GMKN4067B: Serial Programming Cable (RIBless)
Motorola HKN6184: USB Control Head Programming Cable (GCAI)
Following the radio pinout, it’s also possible to build a homemade cable. More info HERE
Antenna Considerations
For the Motorola MTM800E 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
