Charleston City PD and FD are using their assigned P25 talkgroups today. The city system appears to be down-no CC is being broadcast. The only talkgroups that are active are City PD 1 &3, and City FD 1. City Parking Services is using SCTAC-1. I'm not sure if this is a transition to P25 or if this is temporary until the city system is back online.
