Introduction
The Cleartone CM5000 is a rugged mobile radio primarily designed for professional use in industries such as public safety, security, and emergency services. Its durability and advanced features make it well-suited for demanding environments.
There is a DMO repeater mode License available for this model!
Frequency Range from factory:
380 – 430 MHz
Expanded Frequency Range: 380-440MHz
Adaptation for Ham Radio Use
While initially designed for professional applications, the Cleartone CM5000 can be repurposed for Ham radio use with appropriate programming and settings adjustments.
However, it’s important to note that due to the limitations of CPS features and settings, modifications or expansions may not be straightforward.
If repeater mode is activated on the device and it undergoes an upgrade, this function is lost and reactivation with a PIN code is required.
If the PIN code is known, there’s no issue, but if it’s not, it could pose a serious problem as the device is no longer supported and obtaining the code is nearly impossible.
Moreover, the device cannot handle high power in continuous DMO-repeater mode, risking damage to the RF final. Additionally, opening the radio lid triggers a safety switch, resulting in a K-code error, necessitating re-flashing with factory firmware.
Programming
To program the Cleartone CM5000, you’ll need a compatible programming cable. Cleartone usually uses proprietary cables, but for this model, crafting your own programming cable is straightforward by following the pinout on the radio’s back accessory connector.
Programming cable:
The radio can be programmed through its accessory connector using a 3V3 FTDI module. This connection utilizes a four-wire serial connection: RxD, TxD, CTS, and DTR, along with a ground connection. With this setup, the radio can be easily read and programmed.
Programming the CM5000 for Ham radio use involves configuring the device to operate within amateur radio frequency bands and setting up desired channels and features according to Ham radio standards and preferences. You will need:
– CM5000 Native ProgThis is Cleartone programming software specifically designed for the Cleartone CM5000 radio models. This software would be used for configuring and programming the radio’s settings, channels, frequencies, and other parameters directly from a computer.
– Cleartone Application Writer CM5000
This is a program designed for creating and customizing applications for the Cleartone CM5000 radio model.
Depending on the radio firmware version, you might need to update the device firmware or locate the appropriate version of the CM5000 Native Prog software in order to program the radio effectively.
Antenna Considerations
For the CM5000 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
Device Pinout
Understanding the device pinout of the CleartoneCm50000 is essential for ensuring proper connectivity and interfacing with external devices. This includes identifying ports for programming, audio accessories, and other peripherals. Additionally, this understanding aids in the creation of custom-made programming cables to suit specific requirements.

Interfacing with Ham Radio Networks
The Cleartone CM5000 can interface with Ham radio networks using programmed channels and frequencies allocated for amateur radio use. It operates successfully in Direct Mode Operation (DMO), Trunked Mode Operation (TMO), and DMO Repeater mode.
Compatibility with other radio manufacturers
The Cleartone CM5000 integrates effectively into various HamTETRA environments, performing reliably in Direct Mode Operation (DMO), Trunked Mode Operation (TMO), and DMO Repeater mode.
Maintenance and Troubleshooting
Regular maintenance, including battery checks, firmware updates, and cleaning, helps ensure optimal performance and longevity of the Cleartone CM50000. In case of issues or malfunctions, troubleshooting procedures provided by Cleartone or Ham radio communities can help diagnose and resolve problems effectively.
Please note that the Cleartone CM5000, released in 2007, has reached its end-of-life (EOL) status.
In the HamTetra radio community, there’s a notable understanding that radios utilized in DMO Repeater Mode or those modified to increase power often experience failure rates surpassing 55%. The limited availability of replacement parts or accurate documentation poses significant challenges to their repairability.
