There is a definite sub audible tone triggering the repeaters on the P25. I haven't had time to check into it with sigview or my spec a. but the front end of the radios are sometimes triggered before the encryption can change out if its freewheel state. causing dispatch or other systems to drop out.

Etech you are right some pros are working all angles of this. I haven't seen a Stingray II vehicle yet but it would be off grounds and likely at the college parking lot.
