I recently upgraded from a Whistler TRX-2 to the Unident SDS200. Definitely a little brain shift on how they differ in approaches in programming. I live in central MS around the Jackson area where MSWIN dominates for all local, county and state coms. Work has me living in Gulfport about 2 weeks a month so I'm back and forth a lot. Took my new SDS200 down to the coast and found out real quick MSWIN was not the main force down there. Seemed like Waveland / Bay St. Louis had some presence on MSWIN, Jackson County seemed to have their own thing and then Gulfport / Biloxi are all on Harrison County Public Safety system. EDACS ProVoice. I bit the bullet and did the ProVoice upgrade. I've also read that the Harrison County will be soon changing to Harris P25 Phase II, thus MSWIN. Any of the coastal locals have any current updates on this?
