Programming the Motorola GM339 mobile radio requires specific proprietary software, the correct hardware interface, and an understanding of the radio's version history. The GM339 is part of Motorola's "Professional Series" (Warisan), and managing it involves navigating the legacy Customer Programming Software (CPS) environment. 1. Required Software

The primary tool for configuring this radio is the Professional Radio CPS.

Software Version Compatibility: To read or write to the radio, you generally need a version of the Professional Radio CPS (often identified by part number PMVN4039) that is equal to or newer than the version last used to program the device.

Version Examples: Users have reported needing versions such as R03.11.00 or higher to successfully interface with certain GM339 units.

Common Software: While the GM338 and GM339 often share similar families, ensure you use the specific "GP329/339 & GM329/339" software package for full feature access. 2. Necessary Hardware

Unlike modern radios that may use standard USB-to-USB connections, the GM339 requires a specialized interface:

Programming Cable: You will need a cable with an 8-pin (RJ45) connector that plugs into the radio's microphone port.

USB to Serial Interface: Most modern setups use a "RIB-less" USB cable, which contains an internal FTDI serial converter chipset (like the FT232RL) to emulate the older Radio Interface Box (RIB) hardware.

Legacy Connections: If using an older DB9 (9-pin) serial cable, you will likely need a physical Motorola RIB and a power supply to bridge the computer and the radio. 3. Programming Process

Once you have the software and cable, the general workflow follows these steps:

Cable Setup: Connect the USB cable to your PC. Ensure the correct FTDI drivers are installed so the cable appears as a "USB Serial Port" in your Device Manager.

Software Configuration: Open the CPS and select the appropriate COM Port corresponding to your cable.

Reading the Radio: Click the "Read" or "Download" icon. This pulls the current "codeplug" (configuration file) from the radio. Always save a backup of this original file before making changes.

Editing: You can now modify frequencies (VHF or UHF depending on your model), PL/DPL tones, and assign functions to programmable buttons P1 through P4.

Writing to Radio: After editing, click "Write" to upload the new configuration. 4. Common Troubleshooting

Call to Action:

Here’s a draft for a blog post or forum-style guide on Motorola GM339 programming software. You can adjust the tone depending on your audience (ham radio operators, commercial radio techs, or hobbyists).

Title: Programming the Motorola GM339: Software, Cables, and Common Pitfalls

Intro
The Motorola GM339 is a rugged, no-frills analog mobile radio, popular in public safety, commercial fleets, and increasingly with amateur radio operators. But programming one isn’t as simple as plugging in a USB cable. If you’re looking for the right software and a smooth read/write process, here’s what you need to know.

Official Software (Motorola)
The GM339 is programmed using Motorola’s Radio Service Software (RSS) — specifically, the GM339 RSS version R03.00.00 or later.

Compatibility: Runs only in DOS (not natively in Windows 64-bit).
Where to find it: Motorola no longer sells or supports GM339 RSS. You’ll find it via radio forums, Yahoo groups, or used radio dealers.
License required: Officially, Motorola required a software license agreement, but for hobbyist use, most rely on archived copies.

⚠️ Important note: Do NOT confuse GM339 RSS with CPS (Customer Programming Software). CPS is for newer radios like the Mototrbo series. The GM339 uses old-school RSS.

Cable Requirements

Connector: RJ45 (modular) on the radio front panel.
Ribless box required? Unlike the GM300, the GM339 can use a simple Ribless USB programming cable (e.g., FTDI chip based). However, some older RSS versions expect a true RIB (Radio Interface Box) + serial cable.
Recommendation: A “RIBless” USB-to-RJ45 cable labeled for GM339/GM340/GM360 usually works, but if you get “Communication Failed” errors, you may need a genuine Motorola RIB with a serial port.

Step-by-Step (Using DOS RSS)

Set up DOS environment – Use a native DOS PC, DOSBox, or a bootable USB stick with FreeDOS (Windows 10/11’s DOSBox often has timing issues).
Connect the cable – Radio off. Plug into RJ45 port on the front.
Turn radio on – Start with volume at minimum.
Launch RSS – Run GM339.EXE.
Set COM port – In RSS, go to F4 – Setup and match your PC’s COM port (usually COM1 or COM2).
Read radio – F3 – Read → F2 (Radio → Computer). If it fails, check your cable, port settings, and that the radio is in RSS mode (it usually is by default).
Edit frequencies – Enter receive/transmit frequencies, PL tones, scan lists, etc.
Write back – F3 – Program → F2 (Computer → Radio).

Common Errors & Fixes

| Error | Likely Cause | Fix | |-------|--------------|-----| | “Communication with radio failed” | Wrong COM port, cable issue, or radio not powered | Verify cable, try slower baud rate (9600), or use a true RIB | | “Codeplug too new/old” | RSS version mismatch | Find exact RSS version that matches your radio’s firmware | | “Out of range” | Frequency outside radio’s band split (e.g., 146 MHz in a 150–174 MHz model) | Check your GM339’s model number for band limits | | “No response from radio” | Radio not in programming mode or bad connection | Try different USB port, restart DOSBox, or power cycle radio |

Where to get the software
Because Motorola RSS is copyrighted but abandonware, we can’t link directly here. Search for:

“Motorola GM339 RSS R03.00.00 download” on radioreference.com or groups.io
Repeater Builder (repeater-builder.com) – old Motorola software archives

Alternatives?
There are no aftermarket programs like CHIRP for the GM339. You must use Motorola RSS. Some people use DOSBox on a Raspberry Pi to program in the field.

Final Tip
If you’re just getting into programming older Motorolas, keep a dedicated old laptop with a real serial port and Windows 98 or DOS 6.22. It will save you hours of driver headaches.

Title: Finding software for Motorola GM339 (GM340 / GM360 family) To program the Motorola GM339 mobile radio, you

Post:

Hi all,

I’ve just picked up a GM339 and need to read/modify the programming. Before the usual “Google it” replies – I know this radio is from the Professional Series, similar to the GM340, GM360, and GM380.

I want to clarify the software situation because there’s a lot of outdated/bad info out there.

The correct software is: Motorola Professional Radio CPS (Customer Programming Software) – NOT the older RSS (Radio Service Software) that ran in DOS.

Common versions that work with GM339:

CPS R06.12.05 (often cited as the last stable version for this series)
Some earlier R05.x versions also work, but R06.12.05 is generally recommended for Windows XP or a 32-bit Windows 7 machine.

Important notes:

No native 64-bit support – You will need a 32-bit OS or a virtual machine (VMware/VirtualBox) running Windows XP/7 32-bit.
Cable: You need a standard Motorola ribless programming cable for the Professional series (DB9-to-2.5mm/3.5mm jacks). USB-to-serial adapters can work, but only with a good FTDI chip – Prolific clones cause constant errors.
Radio power: The radio must be powered on (12V DC) – the programming cable does not power the GM339.
Reading/Write errors: If you get “Communication with radio failed,” check your COM port settings (4800–19200 baud, 8-N-1 usually works) and ensure no other software is using the port.

Where to get it?

Motorola no longer sells this CPS – it’s end-of-life.
You’ll need to find an archive copy from a reputable radio forum (RepeaterBuilder, Communications.Support, etc.). Do not download random EXEs from sketchy file hosts – scan everything.
Expect to use a cracked/patch if you find a raw installer, as legit Motorola entitlement keys are no longer issued for this CPS.

One final warning: Do NOT try to use GM300 or Maxtrac software. That will not work and could corrupt the radio’s codeplug.

If anyone has a verified working CPS version number or a trick for USB-serial adapters on Win10/11, feel free to chime in.

Cheers

The Invisible Architect: Understanding Motorola GM339 Programming Software Motorola GM339

is more than just a piece of vintage hardware; it is a cornerstone of robust, professional analog communication.

Mastering the Motorola GM339 Programming Software: A Complete Guide

The Motorola GM339 is a workhorse in the world of professional mobile radio. Known for its versatility and ruggedness, it’s a staple for fleets, emergency services, and industrial operations. However, to unlock its full potential—including its 255-channel capacity and advanced signaling features—you need to master the Motorola GM339 programming software.

In this guide, we’ll break down everything you need to know about the software, the hardware requirements, and the step-by-step process to get your radio fleet-ready. What is Motorola GM339 Programming Software?

The GM339 belongs to the Motorola Professional Series (often referred to as the Waris platform). Unlike consumer radios, these units require a specific Computer Business Software (CPS) to configure frequencies, PL tones, button assignments, and signaling protocols like MDC1200 or Quick-Call II.

The software allows you to create a "codeplug"—a data file that acts as the radio's "brain," telling it exactly how to behave on every channel. Essential Requirements

Before you start clicking, you need the right toolkit. Attempting to program the radio with mismatched gear can lead to communication errors or, in worst-case scenarios, a "bricked" radio. 1. The Correct CPS Version

The GM339 typically uses the Professional Radio CPS (common versions include R06.12.05 or similar, depending on your region). Ensure your software version matches the firmware region of your radio (AA for North America, AZ for Asia/Pacific, LA for Latin America). 2. Programming Cable

The GM339 uses an RJ45 (8-pin) connector located on the front microphone port. You will need: An RS232 to RJ45 cable (if you have a native serial port).

A USB to RJ45 programming cable (most common today). Tip: If using USB, ensure the drivers for the Prolific or FTDI chip are correctly installed. 3. A Stable Power Supply

Never program a radio using a weak battery or an unstable power source. If the radio loses power during the "Write" process, it may become unrecoverable. Step-by-Step Programming Guide Step 1: Physical Setup

Connect your programming cable to the PC and the radio’s mic jack. Turn the radio on and ensure the volume is set to a normal level. Step 2: Reading the Radio

Open the CPS software. Always start by clicking "Read Device".

Why? This pulls the current configuration from the radio. It ensures you have a backup and that you are working with the correct frequency bands and settings for that specific hardware.

Save Immediately: Once the read is successful, save this file as "Original_Backup.cp" before making any changes. Step 3: Configuring Conventional Channels

Navigate to the Conventional Personality folder. Here you can: Assign Receive (RX) and Transmit (TX) frequencies.

Set TPL (Tone Private Line) or DPL codes to filter out interference. Adjust power levels (High/Low) for each channel. Step 4: Button and Accessory Configuration

The GM339 has several programmable buttons. Within the software, you can assign these to: Monitor: To open the squelch. Scan: To start/stop scanning lists. Emergency: To trigger a silent or audible alarm. Step 5: Writing to the Radio

Once you’ve input your data, click the "Write Device" icon. A progress bar will appear. Do not touch the cable or the radio until the software confirms the write was successful. The radio will typically reboot once the process is complete. Troubleshooting Common Issues

"Cannot Create Communication Bolt": 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.

"Regional Mismatch": You are trying to use software meant for one region (e.g., Europe) on a radio from another (e.g., Asia). You must use the software version that matches the radio's region.

"Codeplug Version Not Supported": This means your software is older than the firmware in the radio. You will need to source a newer version of the CPS. Conclusion

The Motorola GM339 remains a top-tier analog radio, but its performance is only as good as its programming. By using the correct Motorola GM339 programming software and following a "read-then-edit" workflow, you can ensure your communications remain clear, secure, and professional.

Disclaimer: Always ensure you have the legal right to program and operate on the frequencies you choose. Unauthorized use of restricted frequencies can lead to heavy fines.

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

. Depending on your region, the software version might vary (e.g., AZ for Asia-Pacific). This software allows you to define frequencies, PL/DPL tones, button assignments, and signaling features like MDC1200 or Select 5.

It is important to note that Motorola considers this software proprietary. While many hobbyists seek it out on radio forums or archive sites, it was originally sold through authorized dealers. The Connection: RIB vs. RIB-less

Unlike modern radios that use a simple USB-to-Serial chip, the GM339 originally required a Radio Interface Box (RIB)

. This hardware acts as a voltage level shifter between your computer and the radio. The Classic Way:

A computer serial port connected to a RIB, which then connects to the radio’s microphone jack via a specific cable. The Modern Way:

"RIB-less" USB cables are now common. These have the level-shifting electronics built into the USB connector, mimicking a COM port on your PC. Technical Challenges

Programming this era of Motorola gear often brings two main headaches: Operating System Compatibility:

The older CPS versions were designed for Windows XP or 7. Running them on Windows 10 or 11 often requires "Compatibility Mode" or a Virtual Machine. Baud Rates:

Modern computers are often "too fast" for the legacy handshake protocols of the GM339. Using a high-quality USB-to-Serial adapter (like those with a FTDI chip) is usually necessary to prevent "Communication Error" messages. Why Program a GM339 Today?

Despite being an older model, the GM339 remains a favorite for amateur radio (HAM) use and private commercial networks. Its rugged build and 255-channel capacity make it a workhorse for mobile setups, provided you have the patience to navigate the legacy programming environment. or a specific wiring diagram for the programming cable?

Error 3: "Unlicensed RSS" or "Requires Hardware Key"

Cause: You are using a very old RSS version (R05.xx) that required a hardware dongle in the LPT port.
Fix: Find RSS Version R06.00.00 or newer. These versions bypass the hardware key requirement.

9) Cloning between radios

Use CPS “Clone” or a cloning cable to copy entire configuration from one radio to another.
Verify hardware/firmware compatibility before cloning.

Step 2: Launch RSS

Navigate to your RSS folder (e.g., C:\MOTO\GM300).
Type RSS and press Enter.
You will see a blue Motorola copyright screen. Press any key.
