The GP series of radios are locked to a specific region code by the CPS. Meaning you can’t program US radios with an Australian CPS, for example.
The lock is in the CPS, not the radio, and there’s a registry workaround:
- Install Motorola CPS
- Reboot machine
- Open Regedit
- Go to HKEY_LOCAL_MACHINE -> SOFTWARE -> Motorola -> ProRadio -> FSK
- Edit the string called “SerializedString“
- Replace data with
@%&MAHUS - Open CPS software
Now you can program it regardless of region.
