Rankin is not on the MSWIN yet, only Pearl PD. Hinds has only Byram on the MSWIN. Jackson PD/FD, Clinton PD/FD and HCSO are still on the Hinds TRS. A lot of the counties that have MSWIN, also still use the VHF/UHF freqs. Some have gone pure MSWIN. Warren and Rankin will be transitioning over the next year or so as they convert their TRS's to MSWIN sites. DeSoto will also in the not to distant future. Hinds will most likely also convert to MSWIN as well over the next couple of years as Byram has moved over, and Clinton is joining them... City of Jackson I am curious as to what they will do really, as they upgraded the city's system to an Harris P25ip.... Thus far, only DPW, Water, and JATRAN are on it from my understanding. JPD and JFD are on the Hinds TRS still.
