Programming the Motorola GM950 mobile radio requires specific legacy software and hardware configurations due to its age. Modern versions of Motorola CPS generally do not support this model; instead, it utilizes dedicated Radio Service Software (RSS) originally designed for DOS or early Windows environments. Required Software & Setup
Software Version: The standard software for this series is RSS R02.00.00 or R03.01.08.
Operating System Requirements: The original RSS is a DOS-based application.
Legacy Systems: Ideally run on a true DOS machine or Windows 3.1/95/98 for maximum stability.
Modern Systems (Windows 10/11): Use DOSBox to emulate a slower CPU environment. You must set the DOSBox configuration to a fixed low cycle (around 2500) and map your serial port to COM1 to prevent "too fast" CPU errors that can corrupt the radio's codeplug.
Alternative Tools: Some sources mention a version called wgm950 which may offer better compatibility with later Windows versions like XP. Hardware & Connection Motorola GM950 - software RSS R02.00.00 unpack
The Motorola GM950 is a legacy analog mobile radio that requires specialized hardware and older computing environments for programming. Required Programming Software The official software for this radio is the Motorola Radio Service Software (RSS)
. Because the GM950 is an older model, the software is designed for MS-DOS or early versions of Windows. Software Name: Motorola RSS for GM950 (often found under filenames like or within ARIANE software packs). Operating System: It is highly recommended to use an older PC running Windows 95/98 or a native environment for stable communication. Modern Workaround: On Windows 10/11, you can use with specific CPU cycle adjustments (e.g., cycles=fixed 2500
) to prevent the software from running too fast for the radio's hardware. RADIOSOFTWARE.ONLINE Essential Hardware Programming Cable:
A standard Motorola mobile programming cable that connects to the radio's microphone port (RJ45). RIB (Radio Interface Box):
Unlike modern USB-to-Radio cables, the GM950 typically requires a Motorola RIB
or a RIB-less equivalent to translate the computer's serial signals into a format the radio understands. Serial Port:
A physical RS232 COM port is preferred. If using a USB-to-Serial adapter, ensure it uses a high-quality chipset (like FTDI) to avoid data corruption during the "write" process. Programming Process Preparation:
Connect the radio to a stable 13.8V power supply and attach the programming cable. Reading the Radio: Open the RSS and select the option to "Read Radio"
(often F3 then F2). This saves a backup of your current configuration. Frequency Input:
Enter the desired Receive (RX) and Transmit (TX) frequencies, along with any PL/DPL (CTCSS/DCS) tones for squelch control. Writing to Radio: Once changes are made, select the "Write Radio"
Do not disconnect power or the cable during this process, as it can "brick" the radio. RADIOSOFTWARE.ONLINE Note on Availability:

Motorola GM950 remains a staple in the world of vintage analog mobile radio, prized for its ruggedness and reliability in both commercial and amateur radio (HAM) circles. However, as a legacy device from the "Radius" family, programming it requires a specific set of tools and a deep dive into the technical nuances of late-20th-century computing. The Software: Motorola Radio Service Software (RSS) Unlike modern Motorola units that use the Windows-based Customer Programming Software (CPS) , the GM950 primarily relies on DOS-based Radio Service Software (RSS) Atlantic Radio Communications Corp. Version Specificity:
You must use the RSS specifically designed for the GM950/GM950i series (often designated as or similar). Software for newer models like the CP200 or CM series will not work. The OS Hurdle:
Because it is a 16-bit DOS application, it typically fails on modern 64-bit Windows systems. For the best results, it is recommended to use a "true" DOS environment (MS-DOS 6.22) on an older computer with a physical serial port. While DOSBox can work, it often introduces timing errors that can "brick" the radio. Radiotronics USA Hardware Requirements
To bridge the gap between your computer and the GM950, you need two critical hardware components: Programming Cable: RJ45 mic jack
for programming. You need a cable that terminates in a DB9 (serial) connector. RIB (Radio Interface Box):
This is the most crucial part. Most legacy Motorola radios require a RIB (RLN4008)
to translate the RS-232 levels from the PC to the TTL levels required by the radio. While "RIB-less" USB cables exist, they can be unstable with the GM950's sensitive timing requirements. Motorola Solutions Support Key Programming Features motorola gm950 programming software top
The GM950 software allows for extensive customization of the radio's operation: Frequency Management:
You can program both VHF and UHF frequencies (depending on your specific model) into various "modes" or channels. Signaling: The software supports Select 5 (5-tone)
signaling, which was common in Europe and Australia for selective calling and identification. Power Levels:
You can adjust the high/low transmit power settings to ensure the radio stays within legal limits or extends the life of the PA module. Scan Lists:
Users can define which channels the radio should monitor when the scan function is activated. Technical Challenges & "Bricking" Risks
Programming a GM950 is not without risk. The serial communication protocol used by this era of Motorola hardware is highly sensitive to CPU speed. If you attempt to program the radio using a computer that is "too fast" (e.g., anything above a Pentium II), the RSS may fail to communicate or, worse, corrupt the radio's
. A corrupted codeplug can render the radio useless unless you have a backup file to "force-load" back into the EEPROM. Conclusion
