Operating the Motorola GP88s requires a valid radio frequency license in almost all jurisdictions (such as an FCC license in the United States). Programming your radio to transmit on unauthorized frequencies—such as emergency services, military bands, or commercial frequencies you do not own—is strictly illegal and subject to heavy fines. Always verify your local telecommunications regulations before writing new frequencies to your device. If you need help setting up your system, please tell me: What is your computer running?
