Introduction
The Motorola MTH800 is a robust and reliable TETRA Radio communication device designed for professionals in public safety, emergency services, and other mission-critical sectors. With its rugged construction, advanced features, and seamless integration capabilities, the MTH800 ensures secure and efficient communication in demanding environments. Trusted by organizations worldwide, it offers clear audio, extended battery life, and intuitive operation, making it the go-to choice for those who require dependable communication tools in high-pressure situations.
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 MTH800 has garnered a reputation as one of the most popular choices among the HamTetra radio community, boasting a significant user base and a rich history stemming from its predecessor, the MTH500. While originally crafted for professional applications, its adaptability for ham radio use has been widely recognized.
With straightforward programming to accommodate amateur radio bands, enthusiasts can seamlessly integrate the MTH800 into their setups. Even though the device was discontinued long ago by Motorola, a large number of radios, accessories, and quite a few tricks for ham adaptations can still be found on the market.
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 MTH800, 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 Z19 or RPK. Motorola MTH800 firmware can be upgraded through Motorola Tetra CPS or Motorola Tetra CPS Depot software.
Please refer to the Radio Quick Start Guide or
Motorola Mth800 Upgrade from Legacy to CPS Plus (post FW6511) Version
Programming Cable
Programming the Motorola MTH800 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: PMKN4026A, AAKN4011A, Motorola P2k mobile phones series AAKN4015A can be adapted also.
Antenna Considerations
Motorola MTH800 uses combination GPS/Radio Antenna so when replacing the antenna, it’s important to take into account this factor.
