Connect your cable to the radio's accessory port (usually on the back). Turn the radio on. You should hear a click from the speaker—this indicates the radio is ready.

Motorola holds copyright on all its CPS and RSS. Distribution without license is illegal. However, because the GM950 Plus is discontinued (since the mid-2000s), many hobbyists use archived copies under fair use for maintaining their own equipment. For commercial use, upgrading to a modern radio with legally obtainable software is the correct path.

Disconnect the computer, hook up an antenna (or a dummy load for testing), and press the PTT. You should see the TX light illuminate, and you should hear static on the other channels.

If you have a GM950 Plus and you aren't using the software, you are missing out on 90% of the radio's functionality. Here is what the CPS allows you to control: motorola gm950 plus programming software top

    The programming software for the GM950 Plus is often referred to by its original Motorola designation: Professional Radio CPS (Customer Programming Software).

    The specific version most commonly associated with the GM950 Plus is RVN4196. This software allows you to interface your PC with the radio's logic board to manipulate its "Codeplug." A codeplug is essentially the radio's brain—it contains all the channel data, signaling settings, and menu customizations.

    No software alone programs a GM950 Plus. You need a Motorola RIB (or a RIB-less programming cable with built-in level shifting) and a DB9 serial-to-radio cable. USB-to-serial adapters are notoriously unreliable with this radio; a native serial port is the “top” choice.
