Not to mention that most system operators are not going to allow Cloned ID's to mess with thier system and quickly Stun/Kill the radios. Unlike mixed mode "legacy" type systems where one could set up cloned radios with TX inhibited, P-25 systems query all the radios on the net, and even if the radio is TX inhibited, it still affiliates automatically. (At least on Motorola ASTRO-25 systems, not sure how M/A-Com, and the new EFJ P-25, and IP25 systems do thiers.)
