This forum is dedicated to discussions pertaining specifically to the Motorola ASTRO line of radios (those that use VSELP/IMBE/AMBE), including using digital modulation, digital programming, FlashPort upgrades, etc. If you have general questions please use the General or Programming forums.
Every authorized radio also has a unique 'shadow key' which, if lost, will keep the radio from being rekeyed until that shadow key is restored by manually reloading it from the KMC.
