Is MDOT-J only in the Jackson area?? If it is, then most of the traffic for MDOT-J is going to be on the sites in the Jackson area.. If not, then the traffic you are looking for will be on the site (or sites) that have affiliated with the radio (or radios) on the talkgroup you want to monitor. I assume you want to listen to 22005 (Rail Inspectors). This could be on any site in the state. Remember, a talkgroup can be heard on any site that it is affiliated with. So, what site to use would depend on where the rail inspectors are.
