Click the icon on the toolbar, or select Device > Write .
Configure systems to enable PTT ID, which displays your radio's unique ID on the dispatcher's console when you transmit.
Do not disconnect the cable or power down the radio during this process. Doing so can corrupt the firmware, resulting in a "bricked" radio.
The Motorola GM339 programming software is a tool used to configure and customize the settings of the Motorola GM339 two-way radio. The software allows users to modify various parameters such as frequencies, tones, and channels, as well as set up advanced features like scanning and priority channels.
Legacy CPS was designed for Windows XP, Windows 7, and Windows 8. Running it on Windows 10 or Windows 11 often requires Compatibility Mode (set to Windows 7) and administrator privileges. Required Hardware for Programming
Older serial cables require an external RIB (like the Motorola RLN4008) to handle voltage translation. Modern USB programming cables have the RIB circuitry built into the USB housing (RIB-less), which is highly recommended for convenience.
The Motorola GM339 is a versatile analog mobile radio, but getting it programmed requires a specific combination of "vintage" hardware and precise software. Because these radios are part of the legacy Professional Series (Waris), the process is a bit more involved than modern plug-and-play devices. The Software: Customer Programming Software (CPS) To configure a GM339, you need the Motorola Professional Series CPS
Note: Always read and back up the existing data from the radio before making any modifications. Step 1: Physical Setup Turn off the Motorola GM339 radio.
The GM339 is a powerful radio, and mastering its programming opens up a world of customization, from setting up your favorite HAM frequencies and power levels to designing a complex commercial fleet communication network. With the right tools and a methodical approach, you can unlock the full potential of your Motorola GM339 and integrate it seamlessly into your setup.
The Motorola GM339 belongs to the Professional Radio series (often referred to as the Waris platform). Unlike newer digital radios that use standard micro-USB cables, the GM339 relies on legacy analog programming protocols and specific software versions. Software Compatibility
In the software menu, navigate to > Setup > Comm Port , and select the matching COM port number. Step 3: Reading the Radio (Backing Up)
This is usually a COM port mismatch. Go to File > Setup in the CPS and ensure the COM port matches the one assigned to your USB cable in the Windows Device Manager.
This comprehensive guide covers everything you need to know about the Motorola GM339 programming software, from hardware requirements to step-by-step configuration. Understanding the Software: Motorola CPS
Once you have your cable, you must install the correct driver so your computer can communicate with it.
Program frequencies across VHF (136–174 MHz) or UHF (403–470 MHz / 450–527 MHz) bands.
