Motorola GM338 is a legacy analog mobile radio that requires specific Customer Programming Software (CPS) to configure its 128 channels and features. www.motorolasolutions.com Software Options

While the GM338 is officially discontinued, the software can still be obtained through official and community channels: Motorola Solutions Customer Hub

: The official way to get CPS is through a registered business account on the Motorola Customer Hub Motorola CPS (Customer Programming Software) : This is

. Motorola has made some legacy CPS available for free, but you generally need to register and "purchase" it for $0 to access the download link. Third-Party Repositories : Sites like RadioSoftware.Online

host large collections of legacy Motorola software, including GM series CPS, though these are not official sources. Dealer Support

: Local authorized dealers often provide the necessary software for older units like the GM338 as part of a service package or at a nominal administration fee. Hardware Requirements

To program the GM338, you need more than just software; a compatible interface is essential: Software - Motorola Solutions Support

Is CPS free? CPS Software for MOTOTRBO & ASTRO is free, and can be accessed through the Software Downloads pages linked above. Motorola Solutions Support Motorola CPS is now Free I'm Told! : r/MotorolaSolutions

To program a Motorola GM338 mobile radio, you need the Professional Radio Customer Programming Software (CPS). The GM338 is part of the Waris series, and while newer digital models use MOTOTRBO CPS 2.0, the GM338 relies on an older version of the CPS specific to its firmware. Essential Software & Hardware

To configure the radio effectively, you will need the following components:

Software: The Motorola Professional Radio CPS (frequently version R06.12.05 or similar). This software allows you to adjust a wide array of settings, including channels, zone settings, and scan functions.

Programming Cable: A specific 2-way radio programming cable (typically an RS232 or USB-to-RJ45 connector) is required to link the radio's microphone port to your computer.

Operating System: Most older Motorola CPS versions are designed for Windows (older versions like Windows XP or 7 are often more stable for this legacy software). Key Programming Features

Using the software, you can customize the radio's functionality beyond its default settings:

Channel Configuration: Add, delete, or modify up to 128 channels.

Zone Settings: Group channels into zones for faster switching between frequency groups.

Advanced Safety: Enable the Lone Worker function, which alerts emergency services if the radio is inactive for a set period.

The quest for the best free Motorola GM338 programming software

is a common journey for radio enthusiasts, though it often leads to a complex reality of licensing and regional restrictions. The Best "Free" Software Options and safest way to program a Motorola GM338 is through the GP328/GM338 Customer Programming Software (CPS)

. While historically a paid product, there are legitimate ways to access it: Motorola Solutions Customer Hub

: In some regions, like North America, Motorola has moved toward offering certain CPS versions as a free download . To access this, you must: Motorola Solutions Business Account Motorola Support Portal

Once approved, search for the software (often categorized under "Business Radio CPS" or "Professional Series"). In some cases, the software may be listed at in the shop, allowing you to "purchase" it for free. Version Compatibility : The most frequently used version for the GM338 is the Professional Radio CPS (e.g., version or similar). Ensure you are getting the GP328/GM338

version specifically, as software for newer digital radios (like MOTOTRBO) is not compatible with the analog GM338. Essential Setup Requirements

Even with free software, you will need specific hardware to make it work: Programming Cable : You need a USB-to-RJ45 (8-pin)

programming cable. These are widely available from retailers like Unicom Radio or through AliExpress Operating System : Motorola CPS is strictly Windows-based

. Older versions may require Windows XP or 7 compatibility modes. Hardware Interface

: Modern cables often include a built-in internal converter, so a separate Radio Interface Box (RIB) is typically not required Common Pitfalls Motorola Software Fix Installer Vulnerability

2. Motorola GM338 RSS for DOS (Version 3.0)

If you have a very early model GM338 (firmware before 1999), the Windows CPS might refuse to read it. You need the DOS RSS.

Why it is great: It is almost impossible to brick your radio using DOS RSS. It is tiny (under 1MB) and runs on any old laptop.
How to get it free: Abandonware sites like WinWorldPC often host the Motorola RSS for the GM300 series (which is cross-compatible with early GM338).
The downside: You need a genuine RIB (Radio Interface Box) and a DB9 serial port. USB-to-serial adapters rarely work in pure DOS.

Option B: CHIRP (Open Source – Not Recommended for GM338)

Source: chirp.danplanet.com
Cost: Free (GPL License).
Pros: Excellent for Baofeng/Kenwood; truly free.
Cons: Does NOT support Motorola GM338. CHIRP explicitly lacks the DSP algorithms to decode Motorola’s proprietary codeplug structure. Attempting to force-write will brick the radio.

7. Final Recommendation

4. Hardware Requirements (Critical)

Free software is useless without the correct cable. The GM338 requires a RIB-less USB programming cable (connects to the mic jack). Note the following:

Prolific PL2303 HXA chipset works best with old CPS.
FTDI chipset works with Windows 10/11.
Do not use Windows 11 auto-driver update – it disables fake Prolific chips.

Where to find it (Safely)

Avoid shady "download now" buttons that install malware. The safest sources are user-submitted file sections on trusted forums. Search for "Motorola CPS R06.12.00 download" on reputable ham radio forums. Look for ZIP files containing an installer (Setup.exe) or a folder with a .msi file.

Warning: Always scan any downloaded file with Windows Defender or Malwarebytes. These files are often old and can trigger false positives, but it is better to be safe.
