SCHP Scanning Tips

SC Highway Patrol uses the Palmetto 800 State-wide trunked radio system as its primary communication system. The vast majority of SCHP communications are analog and not encrypted.
There are three basic steps for scanning SCHP:

  1. Selecting appropriate tower sites
  2. Selecting appropriate talkgroups
  3. Programming your scanner
