As far as I know they still have and use the VHF repeater network throughout South/Southeast MS. Only SEMAAD Air Ops had gone pure MSWIN last I knew. Have AAA gone full time on 60000?
Wait.... Why would AAA have anything to do with an transfer out of Brookhaven? That is KDH, and AMR/Rural Metro territory. I could see maybe out of McComb as that is AAA territory alongside AMR/Rural Metro
Kinda figured that lol. Probably an ground unit... have only see an SEMAAD aircraft up in Jackson once or twice ever. And with UMC having AirCARE with AMR its usually AirCARE everywhere for them lol.
