You can get the 10 codes at your local sheriff dept all you got to do is go ask for it and they will give you it
now the siginals they will not give out to you all you got to do is listen and put two and two together and trust me if they are dumb like our department is they will blirt it out somtimes lol !!! the only one i see in the data base is for HWY PATROLL
There are 10 codes listed in the Aiken county RR database along with most of the signals used. These are mostly common codes used all over the state with probably the larger cities excepted. The HP codes are geared more toward traffic violations and road conditions, rarely domestic disputes. Edgefield and Saluda counties use the same 10 codes as Aiken, some of the signals and status codes are different but not all. I do believe that 10-400 is universally used among the rural counties as code for narcotics/trafficking. Check out the SC rural counties in the RRDB. A lot have the codes listed. Have fun listening!
