Custom Buttons: Map the P1–P4 buttons to functions like Scan, Repeater Talkaround, or Emergency Alert. The "Repack" Advantage
When looking for an exclusive download repack, users are typically looking for a streamlined version of the software. A "repack" often includes:
Driver Bundles: Integrated USB-to-Serial drivers for modern Windows versions (Windows 10/11).
Wideband Support: Some repacks are modified to allow 25kHz wideband programming, which is restricted in certain official regional versions.
One-Click Install: Removal of unnecessary bloatware or archaic installation scripts from the original 90s-era installers. Hardware Requirements you avoid malware
Before downloading the software, ensure you have the necessary hardware to bridge the gap between your PC and the radio:
Programming Cable: The GM338 uses a standard RJ45-to-DB9 or RJ45-to-USB cable that plugs into the microphone port on the front of the radio.
PC Connection: If using a DB9 cable, you may need a high-quality USB-to-RS232 adapter (using the Prolific or FTDI chipset).
Power Supply: Always ensure the radio is connected to a stable 13.8V DC power source during programming. A power loss during the "Write" process can brick the radio. How to Install and Use the GM338 CPS 1. Download and Extract
Once you have secured your exclusive download repack, extract the ZIP or RAR folder to your desktop. Ensure you run the setup.exe as an Administrator. 2. Install Drivers
If your repack includes a "Drivers" folder, install these first. This ensures that when you plug in your USB programming cable, the PC assigns it a COM Port (e.g., COM3). You can verify this in the Windows Device Manager. 3. Read the Radio Connect the cable to the radio and the PC. Turn the radio on. Open the CPS software. Go to File > Read Device.
Tip: Always save a backup of the original codeplug (the radio’s data file) before making any changes. 4. Edit and Write
Modify your frequencies in the "Conventional Personality" section. Once finished, click the Write Device icon. Do not touch the cable or the power switch until the progress bar reaches 100% and the radio reboots. Troubleshooting Common Errors
"Couldn't open port": Check your COM port settings in the software (Setup > Communication). Ensure it matches the port assigned in Device Manager.
"Incompatible Radio Model": The GM338 software is region-specific (AZ for Asia, LA for Latin America, AA for North America). Ensure your repack supports your specific model suffix.
Communication Error: This is often caused by a low-quality "clone" cable. If the software fails to read, try a cable with a genuine FTDI chip.
Disclaimer: Programming two-way radios requires a valid radio license (such as an FCC license or local equivalent). Always ensure you are authorized to operate on the frequencies you program into your device. Use third-party software repacks at your own risk.
