clarification to avoid confusion here....
Rebanded and P25 upgrade are 2 entirely different things.
Rebanding is what all 800 systems did to move frequencies around at the FCC's manadate , and that is what Sedgwick County did 2-3 years ago when they dropped all their 859.xxxx frequencies for frequencies in the 854-855 range to get away from the Sprint/Nextel channels. What they are in the process of doing right now is migrating to a P25 digital system. Has nothing to do with rebanding.
