Cross County Sheriff's Office
Public calls for service ring at the county PSAP located at the Sheriff’s Office in Wynne. The lone dispatcher at this PSAP is simultaneously handling multiple agencies [¹] on multiple systems.
Radio traffic includes a mixture of 10 codes and plain English. The Arkansas State Police phonetic alphabet is used.
The communications center answers to either “dispatch,” “S.O.,” or “county.” Cross County Sheriff’s deputies use 200 series callsigns.
The Cross County Sheriff’s Office and Wynne Police Department share a talkgroup. Requests for services are dispatched to the appropriate agency, depending on the location of the request, by making a general call to either “city” or “county.” A Wynne PD officer or CCSO deputy will then answer, and the details of the call are given.
The Cross County Sheriff’s Office is dispatching on the county’s MOTOTRBO DMR system, operating under FCC callsign WRNZ321. The antenna is 120 feet above the ground on a free-standing tower on Baptist Youth Camp Road.
Because this is a DMR system that uses TDMA, it has the built-in capability to support two talkgroups. I’m surprised the second talkgroup isn’t regularly being used for something.
1. The agencies this single dispatcher is fielding calls for include the Cross County Sheriff’s Office, Wynne Police, Wynne Fire, Cherry Valley Police, Cherry Valley Fire, Vanndale Fire, and Hickory Ridge Fire.
