REPORT: Motorola GP88s Programming Software and Cable Requirements

  • Official Software Name: Motorola GP88s Customer Programming Software (CPS).
  • Common Filename: GP88s.exe (often found in archived packages named GP88s_RSS).
  • Operating System Compatibility:
    • Amateur radio forums (e.g., RadioReference, RepeaterBuilder) – search “GP88S CPS R01.00.08”
    • Archive.org – occasionally has user-uploaded copies
    • eBay CD sellers – but risk malware
    • “Communication failed” → check cable, COM port, radio powered ON.
    • “Codeplug too new” → your CPS is older than radio’s firmware – find newer CPS version.
    • “Model mismatch” → you have wrong radio (e.g., GP68, GP328).

    Step 4: Driver Installation (For USB Cables)

    If using a USB cable, install the driver before plugging in the cable. Use the driver CD provided or download the appropriate PL2303/FTDI driver. Reboot after driver installation. motorola gp88s programming software
