The Motorola ASTRO 25 Mobile CPS software reads the radio's information (codeplug data) and allows you to make changes. This information includes the radio serial number, model number, ROM version number, information about the channels (freq, signl, etc.). Once you read a radio you could change the model number or serial number and reprogram the radio to add channels, signaling, etc. but Motorola has taken several precautions so this can not easily be done.
