Districts 4, and 5...
42.1200, and 42.1600 for dispatch.
42.1800, and 42.3000 for mobiles.
45.3200 for the district repeater.
158.9700, and 154.9350 for the mobile repeaters.
You most likely will ony hear the dispatches unless your close to the units.
The good news is that within a few years if all works well, MS will have a statewide TRS..... Most likely an ASTRO-25 one,... unknown yet if they will lean more towards 800, UHF, or VHF yet.
