Introduction
The Motorola MTM5200 is a robust TETRA mobile radio that sits between the MTM800e and the MTM5400 in Motorola’s lineup. Compared to the MTM800e, the MTM5200 offers enhanced audio quality, better coverage, TEDS Ready hardware, USB 2.0 PEI, and advanced encryption. While it lacks some high-end features of the MTM5400, such as higher power output and extensive connectivity, the MTM5200 provides a balanced mix of advanced functionalities and performance, ideal for various professional applications.
The Motorola MTM5200 shares the same hardware as the MTM5400, making it a rare but 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. Although the unit comes from the factory with 3W RF power and without DMO repeater/gateway activation, it can be software-modified with the proper knowledge.
Additionally, there are step-by-step instructions available on how to upgrade it to MTM5400 specifications HERE
Note that Motorola MTM5200 does have a factory default “COR” pinout on the rear accessory connector!
Motorola MTM5200 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 MTTM5200 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!!
