SC Highway Patrol/Department of Public Safety (SC)
From The RadioReference Wiki
The South Carolina Highway Patrol is a division of the SC Department of Public Safety that is responsible for investigating traffic accidents and enforcing traffic laws across the entire state. SCHP is divided into seven troops that each serve several counties. The primary radio system used by SCHP is the Palmetto 800 system. SCHP has the capability of using several other radio systems as well, especially during special events.
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:
- Selecting appropriate tower sites
- Selecting appropriate talkgroups
- Programming your scanner
Selecting Tower Sites
- This map is pretty good for finding county names and interstate routes. Determine your county of interest or the counties you'll pass through on your trip. Create a written or typed list of these counties.
- SC Interstate Routes This lists counties that one passes through while travelling on any of several popular interstate routes, along with Palmetto 800 site numbers for each county.
- Next, look at this current coverage map for Palmetto 800 and determine which tower sites cover your area(s) of interest. Also consult this Google Map of Palmetto 800 and Palmetto P25 tower sites.
- Lastly, consult the site list on the Palmetto 800 database page to determine frequencies for the sites you have selected. Add the site numbers, names and frequencies to your county list. These will be the frequencies you'll program in your scanner.
- Using your county list, look below at the list of SCHP Troops. Determine which Troops you are interested in listening to.
- Again consult the Palmetto 800 database page, this time scrolling down to the Talkgroups section. The first set of talkgroups is for SCHP, and they are sorted by channel number, but are grouped by Troop, starting with Troop 1 channels.
- Each Troop has several dispatch channels (used by one or a group of counties), 2 TAC channels (used for talk-around), and 1 channel each for SC Transport Police, SC DPS (Traffic Management and SCDOT Emergency Responders) and Special Ops.
- Select the talkgroups that you are interested in and jot those down on your list.
- Special Note: Some SCHP dispatch talkgroups are regularly "patched" to each other to allow a single dispatcher to handle multiple channels as a single channel. Different scanners handle this situation differently, but you may find that your favorite SCHP dispatch channel goes quiet for long periods of time. Program all the dispatch channels for the Troop and unlock them when your favorite channel seems to go quiet.
Programming your scanner
It's beyond the scope of this article to provide details on programming every different model of scanner. How you choose to organize your scanner is up to you. But this process should give you the data you need to program the SCHP Talkgroups of the Palmetto 800 system into your radio.
HP unit numbers consist of a letter and a number. The letter indicates the troop/special unit and the number indicates the rank. The lower the number, the higher the rank.
